Answer:

396 formula 72/50 x 275 please give brainliest

Step-by-step explanation:

Answer:

396 tacos

Step-by-step explanation:

for 50 people 72 tacos were sold

for 275 people a tacos were sold

50 people = 72 tacos

275 people= a tacos

cross multiplying

50 × a = 72 × 275

50a = 19800

diving both sides by 50

50a ÷ 50= 19800÷50

a=396 tacos

therefore if 275 people came,396 tacos will be sold

To evaluate the expression 7 - (-7), we can simplify it step by step:

Step 1: Simplify the expression inside the parentheses.

-(-7) = 7

Step 2: Substitute the simplified expression back into the original expression.

7 - (-7) = 7 - 7

Now, let's analyze the given statements:

The expression equals 0.

False. The expression 7 - 7 does not equal 0. It equals 0 when multiplied by (-7), but in this case, the multiplication is not part of the expression.

The expression equals 14.

False. The expression 7 - 7 equals 0, not 14.

The expression is equal to the absolute value of 7.

False. The absolute value of 7 is 7, but the expression 7 - 7 is 0, not 7.

The expression is equal to the opposite of 7.

False. The opposite of 7 is -7, but the expression 7 - 7 is 0, not -7.

Therefore, none of the given statements are true about the expression 7 - (-7).

Answer:

f(x)=−(x+1)2+2g(x)=1/2

Answer:

D. x > dy + c.

Step-by-step explanation:

To solve the inequality x - c/d > y, we'll isolate the variable x.

First, let's multiply both sides of the inequality by d:

d(x - c/d) > dy

Expanding the left side:

dx - c > dy

Next, let's rearrange the terms to isolate x:

dx > dy + c

Finally, divide both sides of the inequality by d:

x > dy/d + c/d

Therefore, the solution to the inequality x - c/d > y, for d > 0, is:

x > dy/d + c/d

7^10 is the answer

Step-by-step explanation:

you just subtract exponents

Answer: The answer is 7^10

Step-by-step explanation:

7^15/7^5 evaluated is 282475249

After evaluating 7^15/7^5 we could then use the process of elimination

- 7^3 = 343

- 7^10 = 282475249

- 7^20 = 1341068619663960000000

and 7^75 = 2.41186503 * 20^63

So, the answer is 7^10

Answer:

Box A's volume is 384.75 cm^3 and Box B's volume is 295.75 cm^3. Box A's volume is greater than Box B's volume.

Step-by-step explanation:

This is a rectangular prism given that the box has different lengths.

Stated dimensions for each box,

Box A:

Length = 13 1/2 (13.5) cm

Width = 3 cm

Height = 9 1/2 (9.5) cm

Box B:

Length = 14 cm

Width = 3 1/4 (3.25) cm

Height = 6 1/2 (6.5) cm

All we have to do, is find the volume of each box, compare them to each other, and determine which volume in which box is the greatest.

Now, in order to find the volume of a rectangular prism, use the formula:

V = L · W · H

Where "L" represents length, "W" stands for width, and "H" represents height.

Given all of these values from the box's dimensions, we only have to plug it in this formula to find the volume.

Let's find Box A's volume:

V = L · W · H

Substitute values:

V = 13.5 · 3 · 9.5

V = 40.5 · 9.5

V = 384.75

Let's find Box B's volume:

V = L · W · H

V = 14 · 3.25 · 6.5

V = 45.5 · 6.5

V = 295.75

Compare the two values to see which is the greatest:

384.75 __ 295.75

384.75 > 295.75, Box A's volume is greater.

Now we know that Box A's volume is 384.75 cm^3 and Box B's volume is 295.75 cm^3. Box A's volume is greater than Box B's volume.

Answer:

First, we need to convert the lengths of the run and rise to inches. 6 ft 8 in. is equal to 72 + 8 = 80 in. and 2 ft 9 in. is equal to 24 + 9 = 33 in.

The guidelines state that the ramp should have a maximum of 1 in. of rise for every 12 in. of run. So, if the ramp has a run of 80 in., the maximum rise should be 80/12 = 6.67 in.

The ramp at the left has a rise of 33 in., which is greater than the maximum of 6.67 in. Therefore, the ramp does not meet the guidelines.

Answer:

(C) x = 56

Step-by-step explanation:

To find the value of x, we first need to find the measure of its supplement, or the angle which, when added to x°, results in 180°, or a straight line.

We can find the measure of its supplement by using the fact that the measures of the interior angles of a triangle add to 180°.

Hence, we can form the following equation to solve for the measure of the supplement.

37° + 19° + s° = 180°

s° = 124°

Now, we can subtract the measure of the supplement from 180° to get x°.

x° = 180° - 124°

x° = 56°

We can cancel the degrees on both sides of this equation to solve for x.

(C) x = 56

The 4th option, (-2)(-2)(-2)

Step-by-step explanation:

Answer:

The team that has the largest overall size hat for their players is the Seahawks; they have a larger mean value of about 23 inches. The correct option is C.

Step-by-step explanation:

What is the mean and median?

The two most frequently used measures of center are mean and median. When we compare the mean numbers for the Falcons and Seahawks, we can see that the Falcons have a mean of roughly 22 inches and the Seahawks have a mean of roughly 23 inches.

Nevertheless, when the data is skewed or contains outliers, the mean may not be the best approximation of the center because the mean can be altered by extreme values or outliers. Thus, we also need to compare the median values. The median is the midway value in the ordered set of data.

Thus, the correct option is C, Seahawks; they have a larger mean value of about 23 inches.

Answer: 21 more miles

Step-by-step explanation:

Gabriel ran  [tex]1\frac{1}{5}[/tex]

Logan ran   [tex]2\frac{1}{4}[/tex]

now we change to an improper fraction

Gabriel  [tex]\frac{6}{5}[/tex]

Logan  [tex]\frac{9}{4}[/tex]

now we find their LCM

LCM of 5 and 4 is 20

we convert the fraction into a number in order to know the miles taken by the two boys

Gabriel

[tex]\frac{6}{5}[/tex]×20 = 5÷20

        =4

   6×4=24miles

Logan

[tex]\frac{9}{4}[/tex]×20=4÷20

       =5

    9×5=45miles

how long Logan took more than Gabriel

45-24=21miles more

Adrian's car travels 15.3 miles less on one gallon of gas than Caroline's car.

A proportional relationship is a type of relationship between two quantities in which they maintain a constant ratio to each other.

The equation that defines the proportional relationship is given as follows:

y = kx.

In which k is the constant of proportionality, representing the increase in the output variable y when the constant variable x is increased by one.

Caroline's equation is given as follows:

y = 44x.

Hence her car travels 44 miles on a gallon of gas.

Adrian's constant is given as follows:

k = 143.5/5 = 287/10 = 28.7.

Hence his car travels 28.7 miles on a gallon of gas.

Hence the difference is given as follows:

44 - 28.7 = 15.3 miles.
