Answer: 39.5 ft^2

Step-by-step explanation:

1. Find the area of the rectangle using the formula length * width

  • 8 ft * 4 ft = 32 ft

2. Find the area of one of the triangles (the top one) using the formula 1/2(b*h)

  • 2 ft * 3 ft * 0.5 = 3 ft

3. Find the area of the other triangle (the bottom one) using the formula 1/2(b*h)

  • 3 ft * 3 ft * 0.5 = 4.5 ft

4. Add 'em all up to get the total area

  • 32 ft + 3 ft + 4.5 ft = 39.5 ft ^2

A circle with circumference 6 has an arc with a 20 central angle,<br> What is the length of the arc?
nirvana33 [79]

Answer:

0.3 units

Step-by-step explanation:

The ratio of the length of the arc to the circumference of the circle is proportional to the ratio of the central angle to the sum of angle in a circle.

\frac{l}{6}=\frac{20}{360}

This implies that:

l=\frac{20}{360}*6

This simplifies to: l=\frac{20}{60}

l=\frac{1}{3}=0.3 units

Two equations are given below: m + 4n = 8 m = n - 2 What is the Solution ?
Sophie [7]
M+4n=8
m=n-2
we see that m=n-2
so we can subsitute 'n-2' for m in the first equation
(n-2)+4n=8
n-2+4n=8
5n-2=8
add 2 to both sides
5n=10
divide by 5
n=2
subsitute
n=2
m=n-2
m=2-2
m=0

m=0
n=2

the answer is c. 0,2
