Answer:

The rate is $3.50 per muffin

Step-by-step explanation:

We have 2 points so we can find the slope (3, 10.5) (6,21)

m = (y2-y1)/(x2-x1)

= (21 - 10.5) /(6-3)

= (10.5)/3

3.5

The rate is $3.50 per muffin

Firlakuza [10]

Answer:

Option C $=8.4672\times10^{13}$

Step-by-step explanation:

Given : Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approximately 5,880,000,000,000 miles.

Suppose a star is 14.4 light years from earth.

To find : How many miles away a star is from earth?

Solution :

In 1 light-year the distance a light can travel is = 5,880,000,000,000 miles.

or = $5.88\times 10^{12}$ miles

In 14.4 lights year the distance is $=14.4\times (5.88\times10^{12})$

$=84.672\times10^{12}$

or $=8.4672\times10^{13}$

Therefore, Option C is correct - $=8.4672\times10^{13}$

Solve the following equation: 8x^2 = 2x

Rzqust [24]

Answer:

x = 0, x = $\frac{1}{4}$

Step-by-step explanation:

Given

8x² = 2x ( subtract 2x from both sides )

8x² - 2x = 0 ( factor out 2x from each term )

2x(4x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0

4x - 1 = 0 ⇒ 4x = 1 ⇒ x = $\frac{1}{4}$

Use the diagram and cosine function to find the value of x.

77julia77 [94]

x=9.4cos(58°)

because the cosine function uses the ratio of the adjacent side to that of the hypotenuse.

9.4 is the hypotenus the ration is 58 degrees I believe

Find the area of this figure

kherson [118]

Step-by-step explanation:

well, I see one large rectangle (20×6), and 2 small triangles with their horizontal sides being (20-8-6)/2 = 3 m. and their vertical joined side being 10-6 = 4 m.

the total area is simply the sum of the rectangle and the 2 triangles.

the rectangle is

20×6 = 120 m²

each triangle is

4×3/2 = 2×3 = 6 m²

we have 2 of them, so their combined area is 2×6 = 12 m².

the total area is

120 + 12 = 132 m²
