Step-by-step explanation:

Julia must sell 21 tacos to meet the requirement .

Given: Price of each taco = $ 3.75

Price of each burrito = $ 6

Total amount of money she needs to earn = $ 330

Also the number of burritos sold= 42.

So the total amount earned on selling these burritos= 42× 6 = $ 252

And as it is given that total money she needs to earn is $ 330 .

so required money= $ 330- $ 252

=$ 78

Thus the total number of tacos she needs to sell = 78/ price of 1 taco

= 78/ 3.75

= 20.8 ≈ 21

Thus Julia must sell 21 tacos to meet the requirement .

Answer:

is there a picture because this can't be solved without a picture

Answer:

m∠TQS = 137°

m∠RQS = 43°

Step-by-step explanation:

It is given that ∠RQT is a straight angle
That means that this angle is 180° and RQT is a straight line

Therefore m∠TQS + m∠RQS = m∠RQT = 180°

Given
m∠TQS = (6x + 20)° and m∠RQS = (2x + 40)°

adding the two angles together will imply
(6x + 20)° +  (2x + 40)° = 180°

=> 6x + 20 + 2x + 4 = 180
=> 6x + 2x + 20 + 4 = 180

=> 8x + 24 = 180

=> 8x = 180 - 24= 156

=> x = 156/8 = 19.5

Substitute for x in  the angle expressions
m∠TQS = 6x + 20 = 6(19.5) + 20 = 117 + 20 = 137°

m∠RQS  2x + 4 = 2(19.5) + 4  = 39 + 4 = 43°
(or we could subtract m∠TQS from 180 to get 180 - 137 = 43°)

Check if they add up to 180°
137° + 43° is indeed 180°

Answer: -8°

A model of a famous statue is  [tex]3\frac{1}{2}[/tex]inches tall. The actual statue is  [tex]5\frac{1}{4}[/tex] feet tall, the ratio of the height of the model to the height of the actual statue in simplest​ form is  [tex]3\frac{1}{2}[/tex]:63

A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of the lemons to oranges is 6:8 (or 3:4). (or 4:7).

A ratio can have any number of quantities, such as counts of people or things or measurements of the length, weight, time, etc. Both the numbers must be positive in most situations.

You can specify a ratio by either writing out both of the integers that make it up, "a to b" or "a:b", or by giving just the value of their quotient a/b. Equal quotients correspond to the equal ratios.

A ratio can therefore be thought of as an ordered pair of integers, a fraction with first number in the numerator and the second in the denominator, or as the value represented by this fraction. Ratios of the counts that are expressed in terms of (non-zero) natural numbers are rational numbers and occasionally natural numbers as well. The ratio of the two numbers is a dimensionless number when they are measured using the same unit, which happens frequently. A rate is product of two quantities that are divided by their respective units of measurement.

Given,

A model of a famous statue is [tex]3\frac{1}{2}[/tex] inches tall.

The actual statue is [tex]5\frac{1}{4}[/tex] feet tall

1 feet = 12 inches

21/4 ft = 12*21/4 inches = 63 inches

Therefore the ratio is

The solution of the inequality is k > 8.82

The expression is in words so we have to convert it to an inequality to be able to solve for k.

An inequality is an expression that has the following symbols: <, >, ≤ and ≥.

Therefore, the inequality can be solved as follows:

k / - 1.8 < - 4.9

Therefore, let's solve for the variable k.

k / - 1.8 < - 4.9

multiply both sides of the inequality by - 1.8

Hence,

k / - 1.8 (-1.8) < - 4.9 (-1.8)

k / 1 > 8.82

Note the sign had to change after we multiply both side of the inequality with a negative number.

Therefore,

k > 8.82

We know that the equation of a line is given by

y = mx + b, where m and b are numbers:

m is the slope of the line and b is the y intercept.

In this case we have the equation:

6 - 2y = - 6

We clear y so we can identify m and b

6 - 2y = -6​

6 = -6​ + 2y

6 + 6​ = 2y

12 = 2y

12/2 = y

6 = y

In this case

y = 6

Then m=0 and b = 6

Here, we are given;

P(A)=0.6

P(B)=0.42

P(B/A)=0.63

We have to find;

Now,

This is the formula for finding conditional probability.

From here,we can see that we have values of P(B/A) and P(A) and we can easily find P(Aand B) from here.

Since P(A)>0 so we can use this formula.

Therefore,

The average rate of change over the interval is 10 and it tells us about the slope

The definition of the function is given as

f(x) = 2.5xsquared + 3

Rewrite the function properly

So, we have the following equation

f(x) = 2.5x² + 3

The interval to calculate the average rate of change is given a

0 ≤ x ≤ 4

This can be represented as

[0, 4]

Further, rewrite as

[a, b] = [0, 4]

Where a = 0 and b = 4

Calculate f(a) and f(b)

So, we have

f(0) = 2.5(0)² + 3 = 3

f(4) = 2.5(4)² + 3 = 43

The average rate of change is then calculated as

Average rate = [f(b) - f(a)]/[b - a]

Substitute the known values in the above equation

So, we have

Average rate = [43 - 3]/[4 - 0]

Evaluate

Average rate = 10

The average rate is the slope of the function

This means that it represents the amount of change in the function with respect to the change in the input variables

The quadratic function has an equation of f(x) = 2x²+ x - 4

From the question, the ordered pairs are given as

(-1, -3), (0, -4), (2, 6)

A quadratic function is represented as

f(x) = ax²+ bx + c

Using the point (0, -4), we have

a(0)²+ b(0) + c = -4

So, we have

c = -4

This gives

f(x) = ax²+ bx - 4

Using the point (-1, -3), we have

a(-1)²+ b(-1) - 4 = -3

So, we have

a - b = 1

Using the point (2, 6), we have

a(2)²+ b(2) - 4 = 6

So, we have

4a+ 2b  = 10

So, we have

a - b = 1

This gives

a = b + 1

Substitute a= b + 1 in 4a+ 2b  = 10

4(b + 1) + 2b  = 10

This gives

4b + 4 + 2b  = 10

Evaluate

6b = 6

Divide

b = 1

So, we have

a = 1 + 1

a = 2

So, we have

f(x) = 2x²+ x - 4

Hence, the equation is f(x) = 2x²+ x - 4

The greatest number of identical packages that Shaquira can make is 2.

Given data:

Shaquira has made 86 chocolate chip cookies and 42 sugar cookies.

Shaquira wants to create identical packages of cookies to sell, and she must use all of the cookies.

To find:

The greatest number of identical packages that Shaquira can make

In order to find the greatest number of packages, we find the HCF of 86 and 42.

Write down this part from the attached image.

Here, 86 = 1 × 2 × 43, 42 = 1 × 2 × 21

Thus HCF = 1 × 2 = 2

So, Shaquira can make 2 identical packages the most.

Each package will have

(86 ÷ 2) = 43 chocolate chips and

(42 ÷ 2) = 21 sugar cookies.

For questions like these you would need to find out the Least Common Multiple, or L.C.M

If Camryn plays the trumpet and the flute today, and they both are in intervals of 11 and 3 days, you would need to find the LCM for 11 and 3.

LCM:

11 = 11, 1

3 = 3, 1

As they both have no common factors, and are prime numbers, multiply 11 x 3 = 33.

So, the least amount of days required for the trumpet and the flute to be played together is 33 days. And the interval between practising them both on the same day is 33 days.

Hence, the number of days until Camryn practices the trumpet and the flute on the same day is 33 days.

Answer:

The answer is most definitely A. It is the only answer that reaches the correct value of 190, which is what 5 * 38 equals. However, to put it into perspective...

Step-by-step explanation:

When we use the distributive property we are breaking down something sometimes, and in this case, very simple into a more extended form.

5 * 38 is the same as saying 5(40 - 2). We also know that if we subtract the sum of 5 * 2 from 5 * 40, it will end up the same as 5 * 38 because you are multiplying 5 two times less.

5 * 40 = 200

5 * 2 = 10

200 - 10 = 190

The answer is A

The word "Houston" can have a maximum of 2520 permutations using all it's letters.

As per the question statement, we are provided with a word: HOUSTON.

And we are required to calculate the total number of permutations that can be formed using all the letters of it.

To solve this question, first we will need to determine the number of letters in our concerned word, which in this case is 7, and then number of repeated letters, which is 2, since the letter "O" is repeated once.

Therefore, the total number of permutations that can be formed using all the letters of the word HOUSTON = [(7!)/(2!)]

                                                         = (7 * 6 * 5 * 4 * 3)
