Answer:

15 muffins

Step-by-step explanation:

We can use proportion to solve this.

Let x be the number of muffins that can be made with 5 cups of flour

4 cups = 12 muffins

5 cups = x

cross-multiply

4×x = 12 × 5

4x = 60

Divide both-side of the equation by 4

$\frac{4x}{4}$ = $\frac{60}{4}$

(On the left-hand side of the equation, 4 on the numerator will cancel-out 4 on the denominator, while on the right-hand side of the equation 60 will be divided by 4)

x = 15 muffins

15 muffins can be made with 5 cups of flour.

A pyramid shaped building is 311 feet tall and has a square base with sides of 619 ft. The sides of the building are made from r

zmey [24]

Answer:

Surface area of the reflective glass is 543234.4 square feet.

Step-by-step explanation:

Given that: height = 311 feet, sides of square base = 619 feet.

To determine the slant height, we have;

$l^{2}$ = $311^{2}$ + $309.5^{2}$

= 96721 + 95790.25

= 192511.25

⇒ l = $\sqrt{192511.25}$

= 438.761

The slant height, l is 438.8 feet.

Considering one reflecting surface of the pyramid, its area = $\frac{1}{2}$ × base × height

area = $\frac{1}{2}$ × 619 × 438.8

= 135808.6

= 135808.6 square feet

Since the pyramid has four reflective surfaces,

surface area of the reflective glass = 4 × 135808.6

= 543234.4 square feet

For two functions, m(x) and p(x), a statement is made that m(x) = p(x) at x = 7. What is definitely true about x = 7? (2 points)

Virty [35]

A)Both m(x) and p(x) cross the x-axis at 7.
B)Both m(x) and p(x) cross the y-axis at 7.
C)Both m(x) and p(x) have the same output value at x = 7.
D)Both m(x) and p(x) have a maximum or minimum value at x = 7.

m(x) = p(x) at x = 7

True statement about x = 7.
C)Both m(x) and p(x) have the same output value at x = 7.
