The unit rate is the cost for 1 pound of grapes.

3 pounds of grapes cost $7.47

1 pound of grape will be: $7.47 / 3 = $2.49

The unit rate is : $2.49 /pound

Answer:

$A_{total} = 25\ ft^2$

Step-by-step explanation:

<u>Step 1: Determine the area of the square</u>

$A = s^2$

$A = (3\ ft)^2$

$A = 9\ ft^2$

<u>Step 2: Split the top figure into a square and triangle</u>

Determine the area of the rectangle

$A = l * w$

$A = (7\ ft - 3\ ft) * (5\ ft - 2\ ft)$

$A = (4\ ft) * (3\ ft)$

$A = 12\ ft^2$

Determine the area of the triangle

$A = \frac{b * h}{2}$

$A = \frac{\frac{7\ ft - 3\ ft}{2} * (5\ ft - 3\ ft)}{2}$

$A=\frac{2\ ft * 2\ ft}{2}$

$A = \frac{4\ ft^2}{2}$

$A = 2\ ft^2$

Since there are two right triangles in the triangle that we have we multiply the area that we got by 2 to get the total area.

$A_{triangle} = 2\ ft^2*2$

$A_{triangle} = 4\ ft^2$

<u>Step 3: Determine the total area</u>

$A_{total} = 9\ ft^2 + 12\ ft^2 + 4\ ft^2$

$A_{total} = 25\ ft^2$

Answer: $A_{total} = 25\ ft^2$

Question mark 1: Match the triangle to correct function and answer

postnew [5]

Answer:

Triangle 1 - $m\angle A = 58^{\circ}$ , hypotenuse = 16

$x \approx 8.479$

Triangle 2 - $m \angle A = 44^{\circ}$ , adjacent leg = 18

$x \approx 17.382$

Triangle 3 - $m\angle A = 49^{\circ}$ , opposite leg = 12

$x \approx 15.900$

Step-by-step explanation:

Each triangle is solved by means of trigonometric relations:

Triangle 1 - $m\angle A = 58^{\circ}$ , hypotenuse = 16

$\cos 58^{\circ} = \frac{x}{16}$

$x = 16\cdot \cos 58^{\circ}$

$x \approx 8.479$

Triangle 2 - $m \angle A = 44^{\circ}$ , adjacent leg = 18

$\tan 44^{\circ} = \frac{x}{18}$

$x = 18\cdot \tan 44^{\circ}$

$x \approx 17.382$

Triangle 3 - $m\angle A = 49^{\circ}$ , opposite leg = 12

$\sin 49^{\circ} = \frac{12}{x}$

$x = \frac{12}{\sin 49^{\circ}}$

$x \approx 15.900$

pogonyaev

Answer:

6/16 or 3/8 (simplified) is your answer.

Step-by-step explanation:

10 children <em>has</em> learned how to juggle 4 balls at a time. There are 16 in all. You are solving for the amount of children that <em>has not learned</em>.

Subtract: 16 - 10 = 6

Set the amount gotten over the total: 6/16

6/16 or 3/8 (simplified) is your answer.
