X2<br>2<br>ab<br>ab to<br>b<br>The diagian<br>K<br>n shows<br>rectangle. The shade<br>Find x.<br>​
Norma-Jean [14]

Answer:

x = 28 cm

Step-by-step explanation:

Given:

Area of link shaded regions = 84 cm²

Required:

The value of x (diameter of the semicircle/length of the rectangle)

Solution:

Diameter of the semicircle = 2r = x

Length of rectangle (L) = 2r = x

Radius of semicircle (r) = ½x

Width of rectangle (W) = radius of semicircle = ½x

Use 3.14 as π

Area of the link shaded regions = area of rectangle - area of semicircle

Thus:

Area of the link shaded regions = (L*W) - (½*πr²)

Plug in the values

84 = (x*½x) - (½*3.14*(½x)²)

84 = x²/2 - (1.57*x²/4)

84 = x²(½ - 1.57/4)

84 = x²(0.5 - 0.3925)

84 = x²(0.1075)

Divide both sides by 0.1075

84/0.1075 = x²

781.4 = x²

√781.4 = x

27.9535329 = x

x = 28 cm

Help me pls and pls explain
Luda [366]

Answer:

5.1 mph

Step-by-step explanation:

she ran 3 2/5 miles in 2/3 hours.

that is the essential information to solve the problem. everything else is just there to give you "atmosphere" and Shao to confuse you.

the question is simply : what was her speed in mph ?

that means we need to bring the ratio of

3 2/5 miles / 2/3 hours

to 1 hour in the denominator (instead of 2/3 hours).

because we need that to express miles per (one) hour.

so, what do we need to multiply 2/3 with to get 1 (=3/3) ?

2/3 × x = 1

2x = 3

x = 3/2

so, to get 1 hour, we need to multiply the denominator by 3/2.

and to keep the original value of the ratio, we need to multiply also the numerator by the same 3/2.

speed = (3 2/5 miles × 3/2) / (2/3 hours × 3/2) =

= (17/5 miles × 3/2) / (1 hour) = 51/10 miles / 1 hour =

= 5.1 miles / 1 hour = 5.1 mph
