The answer to this question based on limits is -4/3

What is limits?

Limits are very interesting concepts in mathematics which are veryuseful when we are dealing with numbers like infinity or numbers where some functions are not defined

Concepts of limits give us brief understanding that why these things are not defined

Solution;

We are asked to calculate a limit

By limits laws we can apply limit to both numerator and denominator respectively

Numerator = lim x--->2 2x-2

= just put 2 in place of x we will get 4 - 2 = 2 ans

Denominator = 2f(3x) - x

put limit as x = 2 in this we get

2 f(6) - 2

we need values of f(6) we can take from graph that f(6) = -3/2

hence answer to our question is 2 divided by -3/2

which in turn our answer for this limit problen is -4/3

Find the values of x and y.

Answers

Answer:

x = 90 , y = 43

Step-by-step explanation:

Since AB and AC are congruent , then Δ ABC is isosceles with base angles congruent , that is

∠ ABD = ∠ ACD = 47°

AD is the perpendicular bisector of BC , so

∠ ADB = x = 90

the sum of the 3 angles in Δ ABD = 180° , then

y = 180° - (90 + 47) = 180 - 137 = 43

Need help:
given that M∠QRT=105, find M∠QRS and M∠SRT​

Answers

Answer:

m∠QRS = 30°

m∠SRT = 75°

Step-by-step explanation:

Given;m∠QRT = 105°m∠QRS = (6x)°m∠SRT = (14x + 5)°To Find;m∠QRS and m∠SRT

Now,

The sum of m∠QRS and m∠SRT is equal to m∠QRT which is 105°

So,

m∠QRS + m∠SRT = m∠QRT

(6x)° + (14x + 5)° = (105)°

6x + 14x + 5 = 105

20x + 105 - 5

20x = 100

x = 100/20

x = 5

Thus, The value of x is 5°

Now,

m∠QRS = (6x)° = 6 × 5 = 30°

m∠SRT = (14x + 5)° = 14(5) + 5 = 70 + 5 = 75°

A toy company is building dollhouse furniture. A rectangular door of a dollhouse has a height of 7 centimeters and a width of 5 centimeters. What is the perimeter of the door on a scale drawing that uses the scale 3:4?

32 cm
24 cm
18 cm
14 cm

Answers

Answer:

Step-by-step explanation:

You need to find the perimeter of the door in the scale drawing.

Not the perimeter of the door on the dollhouse.

If the dollhouse door is 7 cm by 5 cm use the scale factor of 3/4 to

find the dimensions on the scale drawing.

7 times 3/4 = 5.25

5 times 3/4 = 3.75

P = 2(length) + 2 (width)

P = 2 (5.25) + 2 (3.75)

P = 10.5 + 7.5

P = 18 cm

The ratio of Oats to Maple syrup for 36 cookies is 192 grams: 816 grams. So the answer is Option C. 192 grams: 816 grams.

What is Ratio:

Comparing two amounts of the same units and determining the ratio tells how much of one quantity is in the other.

when evaluating the relationship between two quantities or numbers. In general, x: y, which can be interpreted as "x is to y," is used to denote a ratio between two quantities.

Here we have

15 Cookies need 80g Oats

=> Amount of Oats for 1 cookie = 80g/15 gms

So the amount Oats for 36 Cookies = 80g/5 × 36 = 192 grams

15 Cookies need 340 grams of Maple syrup

=> Amount of Maple syrup for 1 cookie = 340/15 gram

So the amount of Maple syrup for 36 cookies = (340/15)×36 = 816 grams

By the above calculations,

For 36 Cookies we need 192 grams of Oats and 816 grams of Maple syrup

The Ratio of Oats to Maple syrup = 192 gram: 816 gram

Therefore,

The ratio of Oats to Maple syrup for 36 cookies is 192 grams: 816 grams. So the answer is Option C. 192 grams: 816 grams.

The amount of time a certain brand of light bulb lasts is normally distribued with a
mean of 1900 hours and a standard deviation of 45 hours. Out of 670 freshly installed
light bulbs in a new large building, how many would be expected to last more than
1890 hours, to the nearest whole number?

Answers

To find the number of light bulbs that are expected to last more than 1890 hours, we need to calculate the area under the normal distribution curve between 1890 and 1900 hours. This represents the probability that a randomly selected light bulb will last more than 1890 hours. We can then multiply this probability by the total number of light bulbs, 670, to find the number of light bulbs that are expected to last more than 1890 hours.

To calculate the area under the normal distribution curve, we first need to standardize the value 1890 hours. This means we need to convert it to a z-score, which represents the number of standard deviations above or below the mean a value is. To standardize a value, we use the following formula:

z = (x - mean) / standard deviation

In this case, we have x = 1890, mean = 1900, and standard deviation = 45, so the z-score is:

z = (1890 - 1900) / 45 = -0.22

We can now use this z-score to look up the corresponding area under the normal distribution curve using a table of the standard normal distribution. This table gives the area under the curve between the mean and a given z-score. Since our z-score is negative, we need to look up the area to the left of the mean. In this case, the area is 0.4162.

We can now multiply this probability by the total number of light bulbs, 670, to find the number of light bulbs that are expected to last more than 1890 hours. This is:

0.4162 * 670 = 278.29

Rounded to the nearest whole number, this is 278 light bulbs. So we would expect about 278 out of 670 freshly installed light bulbs in the new large building to last more than 1890 hours.

The answer is 278 light bulbs.

Triangle ABC is a right triangle, with right angle B. Side AC has a
length of 13. Side AB has a length of 5. Find the length of side
CB.

Answers

The length of side BC is approximately 10.928.

What is the right triangle?

In a right triangle, the side opposite the right angle is called the hypotenuse. In triangle ABC, side AC is the hypotenuse, and sides AB and BC are the other two sides.

To find the length of side BC, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

We can use the given information to write the Pythagorean theorem in the form:

AC^2 = AB^2 + BC^2

Substituting the given lengths, we get:

13² = 5² + BC²

Solving for BC, we get:

BC = √(13² - 5²)

= √(144 - 25)

= √(119)

= approximately 10.928

Therefore, the length of side BC is approximately 10.928.

Answers

The correct values for A, B and C are given as follows:

A = 9.B = 26.C = 104.

How to obtain the correct values for A, B and C?

The table shows the ratios of black to white keys on pianos of various sizes, and these ratios are constant, meaning that the following proportional relationship is established:

A/13 = 18/B = 45/65 = 72/C

Then the value of A can be obtained as follows:

A/13 = 45/65

Applying cross multiplication, we have that:

65A = 13 x 45

A = 13 x 45/65

A = 9.

The value of B can be obtained as follows:

18/B = 45/65

Applying cross multiplication, we have that:

45B = 18 x 65

B = 18 x 65/45

B = 26.

You deposit $600 in a savings account. After 18
months, you check your statement and see that
you have earned $31.50 in interest. What is the
interest rate for your account?

Answers

Answer:

To calculate the interest rate for your account, you will need to use the formula for simple interest:

Interest = Principal x Rate x Time

In this case, the principal is the amount of money you deposited, or $600. The time is the number of months the money was in the account, or 18 months. And the interest is the amount of money you earned, or $31.50.

Plugging these values into the formula, we get:

$31.50 = $600 x Rate x 18

To solve for the rate, we can divide both sides of the equation by $600 and 18:

Rate = $31.50 / ($600 x 18)

Simplifying this expression gives us:

Rate = 0.01625

So, the interest rate for your account is approximately 1.625%.

Answers

A class is planning a trip to the local City Museum of Art. The class needs 3 trucks and 1 car to transport all 22 people on the trip.

What is the system of equations?

Generally, To solve this problem, we can set up a system of equations using the information given. Let C be the number of cars needed and T be the number of trucks needed.

The first equation will represent the number of people that can be transported in the cars: 4C + 6T = 22

The second equation will represent the number of drivers: C + T = 4

Now we can solve this system of equations using elimination or substitution.

Using elimination, we can multiply the first equation by 2 and the second equation by 4 to get: 8C + 12T = 44 4C + 4T = 16

Then we can subtract the second equation from the first equation to get: 4C + 8T = 28

Then we can divide both sides by 4 to get: C + 2T = 7

Then we can substitute this value for C in the second equation to get: 7 - 2T = 4 T = 1.5

Since T represents the number of trucks, which must be a whole number, this solution is not possible.

Using substitution, we can solve for C in the second equation and substitute it into the first equation: C = 4 - T 4(4 - T) + 6T = 22 16 - 4T + 6T = 22 2T = 6 T = 3

Substituting this value for T into the second equation, we get: C = 4 - 3 C = 1
