Answer: 15(30 +33) = 945

Step-by-step explanation:

First, you have to distribute the 63 and make it smaller to become 30 + 33. So, the equation would be 15(30 + 33) = 450 + 495 = 945

Sav [38]

Answer:

x=y

Step-by-step explanation:

let x be the number of tennis balls and y the number of rackets.

-We divide the number of balls by the number of rackets to find out their ratio of proportionality:

$\frac{x}{y}=\frac{5}{5}=\frac{1}{1}=1$

-Hence, for each one ball there is one racket, so;

$x=y$

-This relationship is linear in nature, a direct variation, and can be graphed as attached below:

Answer:

126 square units

Step-by-step explanation:

Area of section 1 is 8 square units which is triangle and,

Area of triangle is = $\frac{1}{2}\times b\times h$

b= 2 units and height =8 units

So,

Area of section 1 = $\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}$

Same Area is of section 2 which is also a triangle and has same base and height.

So,

Area of Section 2 = $\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}$

Now the Area of section 3 which is square with side of 10 units

So,

Area of section 3 = $a^{2} =10\times10=100\quad \text{square units}$

Total Area of Trapezoid = $8+8+100=126 \quad \text{square units}$
