What is the area of this figure?
Dima020 [189]

Answer:

220.5 \:  {yd}^{2}

Step-by-step explanation:

Area of the figure = Area of the arc with radius 10 yd and central angle 90° + Area of rectangle with dimensions (10 + 5 - 3 = 12) 12 yd and (7 + 6 - 4 = 9) 9 yd + Area of square with dimension 4yd + Area of rectangle with dimensions 3 yd by 2 yd + Area of triangle with base 3 yd and height (5 + 3 = 8) 8 yd.

=  \frac{90 \degree}{360 \degree}  \times 3.14 {(10)}^{2}  + 12 \times 9 +  {4}^{2} \\ + 3 \times 2 +  \frac{1}{2}  \times 3 \times 8 \\  \\  =  \frac{1}{4}  \times 314 + 108 + 16 + 6 + 12 \\  \\  = 78.5 + 142 \\  \\  = 220.5 \:  {yd}^{2}

Answer:

it's 1/7^2

Step-by-step explanation:

When multiply bases with exponents, as long as they are the like bases, you add the exponents. 7^3 x 7^-5 = 7^-2.

When you have a negative exponent, you can get rid of it by moving it to a fraction. put a 1 over the base and exponent and drop the negative, so 1/7^2

Suppose PR = 54, solve for QR
kenny6666 [7]

We will use the segment addition postulate.

PQ + QR = PR

4x - 1 + 3x - 1 = 54

7x - 2 = 54

7x = 56

x = 8

So QR is 3(8) - 1 or 24 - 1 which is 23.
