Mari makes bows for floral arrangements she uses 1/8 yard of ribbon for each bow .how many bows can she make from 24 yards of ribbon

Answers

Answer 1

First, you need to find out how much ribbon she has total. Because there are two spools, you multiply 24 x 2. The answer for that is 48. Then you have to figure out how many bows she can make. Each bow uses 1/8 of a piece of yard of ribbon, so you can divide 48 by 8. Your answer would then be 6 bows.

Here are the equations.

[tex]24\times2 = \text{X}[/tex]

[tex]\dfrac{\text{X}}{8} =\text{B}[/tex]

Where X represents the yards of ribbon available and B represents the number of bows that Mari can make.

Complete Question:

Mari makes bows for floral arrangements. She uses 1/8 of a yard ribbon for each bow. How many bows can she make from 2 spools that each has 24 yards ribbon?

Cheese costs $4.40 per pound. Find the cost per kilogram. (1 kg ≈ 2.2 lb)

Answers

The cost per kilogram of cheese is found by dividing the cost per pound by the conversion factor 0.45359237 kilograms per pound. The result is $9.68 per kilogram.

Start with the given cost of cheese per pound: $4.40.

To convert from pounds to kilograms, we need to divide by the conversion factor 2.2 (since 1 kilogram is approximately equal to 2.2 pounds). So, we have

1 pound / 2.2 = 0.45359237 kilograms / 1 pound

Note that we can write this as a conversion factor with the pound unit cancelling out, leaving us with kilograms as the desired unit.

Now, we can multiply the cost per pound by the conversion factor to get the cost per kilogram

Cost per kilogram = Cost per pound * (1 pound / 0.45359237 kilograms)

= $4.40 * (1 / 0.45359237)

Evaluating this expression using a calculator gives us

Cost per kilogram = $9.68

So the cost of cheese per kilogram is approximately $9.68.

What is exponential function?

A mathematical function called an exponential function is employed frequently in everyday life. It is mostly used to compute investments, model populations, determine exponential decline or exponential growth, and so forth.

If the base is larger than 1, it will be an exponential growth.

For example, [tex]3^2=9[/tex]

If the base is smaller than 1, it will be an exponential decay.

For example, [tex]0.5^2=0.25[/tex]

if at least one child in a family with 2 children is a boy, what is the probability that both children are boys?

Answers

Answer:

The probability of both children being boys in a family with 2 children is

There are 3 possible outcomes for the gender of each child: boy, girl, or unknown. There are 2 children, so there are 3

=9 possible combinations of genders for the 2 children.

Of these 9 combinations, 3 of them have both children being boys: BB, BG, and GB. So the probability of both children being boys is

However, this is only the probability if we don't know the gender of the first child. If we know that the first child is a boy, then the probability of both children being boys is

. This is because there are only 2 possible outcomes for the gender of the second child: boy or girl. If the first child is a boy, then the second child must be a boy in order for both children to be boys. So the probability is

Step-by-step explanation:

Let's use the following notation for the children:

B: Boy G: Girl

There are 4 possible combinations for a family with 2 children:

1. BB (Both children are boys)

2. BG (First child is a boy, second child is a girl)

3. GB (First child is a girl, second child is a boy)

4. GG (Both children are girls)

Since we know that at least one child is a boy, we can eliminate the 4th combination (GG) as it doesn't meet the condition. Now we have 3 possible combinations left:

1. BB

2. BG

3. GB

Now, to find the probability that both children are boys (BB) from the remaining combinations, we can calculate it as follows:

Probability = (Number of favorable outcomes) / (Total possible outcomes)

Probability = 1 (BB) / 3 (BB, BG, GB)

Probability = 1/3

So, the probability that both children are boys is 1/3.

Find a formula that represents the number of red roses left t hours before the store opens. b. Find a formula that represents the number of box chocolates left t hours after the store opens. c. At what time will the number of roses be equal to the number of boxes of chocolates. d. How many boxes of chocolate are left at 12:30 in the afternoon? Round your answer to make sense in this context of the problem. e. Suppose you want to buy that special someone 36 red roses at the store. What is the latest you can arrive to successfully make your purchase?

Answers

Answer:

Step-by-step explanation:

a. The number of red roses left t hours before the store opens can be represented by the formula:

N(t) = 400 * (1/2)^(t/2)

Here, we're dividing the number of available roses by 2 every 2 hours, so the exponent t/2 represents the number of 2-hour intervals that have passed since the store opened.

b. The number of box chocolates left t hours after the store opens can be represented by the formula:

M(t) = 200 * (0.85)^t

Here, we're multiplying the number of available boxes by 0.85 every hour, so the exponent t represents the number of hours that have passed since the store opened.

c. We need to find the time t when the number of roses is equal to the number of boxes of chocolates:

400 * (1/2)^(t/2) = 200 * (0.85)^t

Dividing both sides by 200:

2 * (1/2)^(t/2) = 0.85^t

Taking the logarithm of both sides:

log(2) - (t/2) * log(2) = t * log(0.85)

Simplifying:

t * (log(0.85) + (log(2)/2)) = log(2)

t = log(2) / (log(0.85) + (log(2)/2))

Using a calculator, we get:

t ≈ 11.9 hours

Therefore, the number of roses will be equal to the number of boxes of chocolates approximately 11.9 hours before the store opens, or around 9 p.m. on the day before Valentine's Day.

d. To find the number of boxes of chocolate left at 12:30 p.m. (3.5 hours after the store opens), we can use the formula:

M(3.5) = 200 * (0.85)^3.5

M(3.5) ≈ 97.4

Therefore, there are approximately 97 boxes of chocolate left at 12:30 p.m.

e. To buy 36 red roses, we need to find the latest time we can arrive before the store runs out of roses. We can set N(t) equal to 36 and solve for t:

400 * (1/2)^(t/2) = 36

Dividing both sides by 400:

(1/2)^(t/2) = 0.09

Taking the logarithm of both sides:

t/2 * log(1/2) = log(0.09)

Simplifying:

t ≈ 5.2 hours

Therefore, the latest time we can arrive to successfully buy 36 red roses is approximately 5.2 hours before the store opens, or around 3:50 a.m. on the day before Valentine's Day.

Question 1: The side length c of the triangle is equal to: c 2 =a 2 +b 2 −2abcosC where a and b are the other two side lengths of the triangle, and C is the angle opposite side c. To solve for c, you can plug in the values of a, b, and C into the formula and solve for c. For example, if a=3, b=4, and C=60 ∘ , then you would plug in these values into the formula and solve for c as follows: c 2 =3 2 +4 2 −2⋅3⋅4cos60 ∘ c 2 =25 c= 25 =5 Therefore, the side length c of the triangle is equal to 5. Question 2: The angle C of the triangle is equal to: cosC= 2ab a 2 +b 2 −c 2 where a, b, and c are the other two side lengths of the triangle. To solve for C, you can plug in the values of a, b, and c into the formula and solve for C. For example, if a=3, b=4, and c=5, then you would plug these values into the formula and solve for C as follows: cosC= 2⋅3⋅4 3 2 +4 2 −5 2 =− 4 1 C=cos −1 (− 4 1 )≈109.47 ∘ Therefore, the angle C of the triangle is approximately 109.47 degrees. Question 3: The area of the triangle is equal to A= 2 1 absinC where a and b are the other two side lengths of the triangle, and C is the angle opposite side c. To solve for A, you can plug in the values of a, b, and C into the formula and solve for A. For example, if a=3, b=4, and C=60 ∘ , then you would plug in these values into the formula and solve for A as follows: A= 2 1 ⋅3⋅4sin60 ∘ =6 3 Therefore, the area of the triangle is equal to 6 3 . Question 4: The perimeter of the triangle is equal to: P=a+b+c where a, b, and c are the three side lengths of the triangle. To solve for P, you can simply add up the values of a, b, and c. For example, if a=3, b=4, and c=5, then you would add up these values to get P=12. Therefore, the perimeter of the triangle is equal to 12. Question 5: The centroid of the triangle is located at a point that is: One-third of the way from each vertex to the opposite side. Equidistant from all three vertices. On the medians of the triangle. To find the centroid of the triangle, you can use the following formula: G=( 3 a+b+c , 3 a+b+c , 3 a+b+c ) where (a,b,c) are the coordinates of the three vertices of the triangle.

In other words, the P-value is the probability of obtaining a sample proportion of 0.15 or less (which corresponds to 10 black cars out of 70 total) if the true proportion of black cars that receive moving violations is actually 0.19.

Since the P-value is relatively high (larger than the significance level of 0.05), we fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim that black cars are less likely to receive tickets for moving violations.

So, the correct answer is C).

Answers

Answer:

WX = 34 units

---------------------

WX and YX are tangents drawn from point X to circle Z.

Tangent segments drawn to the same circle from the same point are equal:

WX = YX

Substitute values for side lengths and solve for x:

7x - 29 = 2x + 167x - 2x = 16 + 295x = 45x = 9

Substitute 9 for x and find the length of tangent WX:

WX = 7*9 - 29 = 63 - 29 = 34

The equation of line perpendicular to the tangent is found to be -

y = -2x + 7.

Give an explanation of the slope-intercept form:

The equation for a line should be written in the slope-intercept form so that the y-intercept (where its line crosses a vertical y-axis) and slope (steepness) are immediately visible. The y = mx + b form is a common name for this form.

Given condition of digression line:

Comparing with the standard form: y = 1/2 x + 7 y = mx + c

m is the slant and c is the y block:

m = 1/2

Let the incline of the line opposite to the digression be M.

Then, at that point, connection between the inclines of opposite lines:

m. M = -1 equation of line perpendicular to the tangent.

y - 3 = M(x - 2)

y - 3 = -2(x - 2)

y = -2x + 4 + 3

y = -2x + 7

Thus, the equation of line perpendicular to the tangent is found to be -

y = -2x + 7.

The interest earned on rs15000 in 3 years at simple interest is rs5400 find the rate of interest per anunm

Answers

Answer:

12%

Step-by-step explanation:

Let the rate of interest be R%
r = R% as decimal =R/100

Simple interest earned for 3 years at rate r on ₹15,000 = ₹5,400

The formula for interest earned is given by
I = Prt
where P is the principal amount (15,000)

r = annual interest rate as a decimal (to be determined)

t = number of years

Plugging in known values we get

5400 = 15000 x r x 3

= 45000 x r

r = 5400/45000

r = 0.12

Rate of interest as a percentage = r x 100 = 0.12 x 100 = 12%

The length of the two unknown sides of the triangle are: 12√2

How to find the missing lengths of the triangle?

There are different methods of finding the missing sides of triangles such as:

Pythagoras Theorem

Law of sines or sine rule

Law of cosines or cosine rule

Now, we are given an Isosceles triangle with a base length and two equal base angles.

Thus, the two unknown sides will have equal side lengths.

∠D = 90°

Thus, using sine rule:

12/sin 90 = QR/sin 45

QR = 12 * 1/√2

Rationalizing the denominator gives:

QR = 12√2

Since the two unknown sides of the triangle are equal, then we say that:

Felix is purchasing a brownstone townhouse for $2,500,000. To obtain the mortgage, Felix is required to make a 18% down payment. Felix obtains a 30-year mortgage with an interest rate of 6.5%.

a) Determine the amount of the required down payment.
b) Determine the amount of the mortgage.
c) Determine the monthly payment for principal and interest.
quiz

Answers

a) The down payment required would be 18% of the purchase price of the townhouse, which is $2,500,000. Therefore, the down payment required would be:

Down payment = 0.18 x $2,500,000 = $450,000

b) The amount of the mortgage would be the difference between the purchase price of the townhouse and the down payment. Therefore, the amount of the mortgage would be:

Mortgage = $2,500,000 - $450,000 = $2,050,000

c) The monthly payment for principal and interest can be calculated using the loan amount, interest rate and loan term. For a 30-year loan with an interest rate of 6.5%, the monthly payment formula is:

Monthly payment = (P x (r/12)) / (1 - (1 + r/12)^(-n*12))

Where P is the loan amount, r is the interest rate (as a decimal), and n is the number of years. Plugging in the values, we get:

Monthly payment = ($2,050,000 x (0.065/12)) / (1 - (1 + (0.065/12))^(-30*12))
= $12,973.47

Therefore, the monthly payment for principal and interest would be $12,973.47.
