Answer:

Step-by-step explanation:

Formula

The area of a Trapezoid is given as

A = (b1 + b2)*h/2

Givens

b1 = 8

b2 = 4

h = 4

Solution

Area = (8 + 4)*4/2

Area = 12*4/2

Area = 24

vredina [299]

Answer:

$5\ batches\ of\ cookies$

Step-by-step explanation:

we know that

Karl makes 7 1/2 batches of cookies using 1 1/2 dozen eggs

so using proportion

Find out how many batches of cookies could he make with a dozen eggs

step 1

Convert mixed numbers to an improper fraction

$7\frac{1}{2}=\frac{7*2+1}{2}=\frac{15}{2}$

$1\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}$

step 2

Applying proportion

Let

x ----> the amount of batches of cookies

$\frac{(15/2)}{(3/2)}\frac{batches}{dozen\ eggs}=\frac{x}{1}\frac{batches}{dozen\ eggs}\\\\x=\frac{15}{3}\\\\x=5\ batches\ of\ cookies$

Evaluate the function at the given value and simplify.

Licemer1 [7]

Answer:

The correct option is b.

Step-by-step explanation:

The given function is

$f(x)=-5x+1$

We need to find the value of f(-2). It means we have to find the value of given function at x=-2.

Substitute x=-2 in the given function to find the value of f(-2).

$f(-2)=-5(-2)+1$

On simplification we get

$f(-2)=10+1$

$f(-2)=11$

The value of f(-2) is 11. Therefore the correct option is b.
