The perimeter of a rectangle is less than or equal to 50 inches. The length of the rectangle is 10 inches. What inequality repre

kupik [55]

Answer:

w ≤ 15

Step-by-step explanation:

A rectangle is shape with 4 sides where 2 pairs of sides are equal and form 4 perpendicular angles. 1 pair of sides is the width and is distance w. 1 pair of sides is the length and is 10 inches. The total distance around the shape is the perimeter. We know the perimeter is 50 inches or less. Add each side together and let it be less than or equal to 50. Then solve for w.

P ≥ l + l + w + w

50 ≥ 10 + 10 + w + w

50 ≥ 20 + 2w

30 ≥ 2w

15 ≥ w

Find the area of the shaded region. Round your answer to the nearest hundredth.

Lerok [7]

Answer:

1.44 units²

Step-by-step explanation:

The angle for the big triangle is 60°, so the smaller triangle is 30°

so to find the base of the small triangle you can do tan 30 = X/2 $\sqrt{3}$

so x is 2, which means that the base of the big triangle is 4.

The area of the big triangle is 1/2bh = 1/2(4)(2 $\sqrt{3}$ ) = 4 $\sqrt{3}$ = 6.93

Find hypotenuse (radius) using Pythagorean Theorem r = 4

The area of the piece of pie is $\pi r^{2} *60/360$ = 8.37

8.37 - 6.93 = 1.44
