Answer:

Perimeter b = circumference b = 10π; Area b = 50π

Perimeter c = circumference c = 10.5π; Area b = 27π

Step-by-step explanation:

b. Circumference = perimeter

Circumference of semicircle= πr=10π =Perimeter

Area of semi circle=πr^2/2=10^2π/2=50π

c. Circumference = 7/4πr=1.75*6π=10.5π=Perimeter

Area of the diagram = 3/4πr^2=0.75π*6^2=0.75π*36=27π

why do whole numbers raised to an exponent get greater while fractions raised to an exponent get smaller?

ehidna [41]

Any number above 1 gets greater, below 1 smaller (when above 0), while 1 itself remains the same. Negative numbers are more unpredictable.

Pinto is planning to paint the walls of a bedroom that is 20 feet long, 15 feet wide, and 8 feet high. Is he too has 1 gallon of

eimsori [14]

Answer:

0.4 gallons

Step-by-step explanation:

Length of a bedroom= 20 feet

Breadth of a bedroom= 15 feet

Height of a bedroom= 8 feet

Area of walls of a bedroom= 2(l+b)×h

Area of walls of a bedroom=2(20+15)×8 $ft^{2}$

Area of walls of a bedroom= 2× 35×8 $ft^{2}$

Area of walls of a bedroom=560 $ft^{2}$

Amount of paint in 1 gallon = 400 $ft^{2}$

Number of gallons required= $\frac{560}{400}$

Number of gallons required= 1.4 gallons

Hence, 0.4 extra gallons required

Solve by graphing.

const2013 [10]

Answer:

(4,4)

Step-by-step explanation:

y = 2x - 4 -------eqn 1

4y = x + 12 ------eqn 2

From eqn 1 y = 2x - 4; insert in eqn 2

4 (2x-4) = x + 12 (open the bracket)

8x - 16 = x + 12 (taking like figures to the same side, sign changes)

8x - x = 12 + 16

7x = 28

x = 28/7

x = 4

From eqn 1

y = 2x - 4

y = 2(4) - 4

y = 8 - 4

y = 4

(x,y) = (4,4)
