The answers are 5 and -2. This is because 5 times -2 equals -10 and 5 plus -2 equals 3.

Correct answer = BRAINLIEST PLZZZZZ HELPPPP

dybincka [34]

Answer:

A) 3 cups

B) $40.50

Step-by-step explanation:

Part A

Step 1 - divide the target number of pralines by the number the recipe makes:

108 ÷ 18 = 6

Step 2 - multiply this number by the amount of light cream in the recipe for one batch:

$\frac{1}{2} * 6 = 3$

This means that 3 cups are needed.

Part B

Step 1 - Divide the total pralines by 4:

108 ÷ 4 = 27

Step 2 - Multiply this number by the price Kia is going to sell them:

1.50 * 27 = 40.5

So she will make $40.50 for the school.

Hope this helps!

As John walks 16 ft towards a chimney, the angle of elevation from his eye to the top of the chimney changes from 30° to 45°. Id

levacccp [35]

ANSWER

The height is $22ft$

EXPLANATION

Let the height of the chimney be x.

$\tan(45 \degree) = \frac{x}{y}$

$1 = \frac{x}{y}$

$x = y$

$\tan(30 \degree) = \frac{x}{16+ y}$

$\frac{ \sqrt{3} }{3} = \frac{x}{16 + y}$

Cross multiply

$\sqrt{3} (16 + y) = 3x$

$16 \sqrt{3} + y \sqrt{3} = 3x$

Put

$y = x$

into the equation;

$16 \sqrt{3} + x \sqrt{3} = 3x$

Group similar terms:

$16 \sqrt{3}= 3x - x \sqrt{3}$

$16 \sqrt{3}= (3 - \sqrt{3})x$

$\frac{16 \sqrt{3} }{3 - \sqrt{3} } = x$

$x=21.856$

The height of the chimney to the nearest feet is 22
