Answer:
t = 1/2 ÷ 1/4
t = 2 hours
Step-by-step explanation:
Time spent watching movies = 1/2 of an hour
This accounts for 1/4 of the total time thei spend at mount rushmore.
1/2 = 1/4t
Where t = total time they spent at mount rushmore (hours)
1/2 = 1/4t
Determine the equation to find t
t = 1/2 ÷ 1/4
= 1/2 × 4/1
= 4 / 2
= 2
t = 2 hours
Just find the surface area. 5*7=35, but 35*2=7<span>0</span>, because the top and bottom. Then do 7*3*2=42, for 2 parallel sides, and then 3*5*2=30. Now add 70+30+42=142 square inches. There's your answer.
Answer:
a = 6
Step-by-Step Explanation:
9 + 8a = 57
8a = 57 - 9 (subtract 9 from both sides)
8a = 48 (then divide 8 from both sides to get "a" alone)
a = 48/8
a = 6
The sector of a circle with a measure of 36° and radius of 12 cm has an arc length of about 7.5 cm
A circle is the locus of a point such that the distance from the fixed point is constant.
The perimeter of a sector is given by:
Perimeter = (θ/360) * 2πr
Where θ is the central angle, r is the radius of the circle
Given a radius of 12 cm and angle of 36°:
The arc length = (36/360) * 2π(12) = 7.5 cm
Hence the sector of a circle with a measure of 36° and radius of 12 cm has an arc length of about 7.5 cm

The probability that 2 will land face down is 1/4 (one 2/4 possibilities)
So to find out not a 2 you would take 1 - 1/4 = 3/4 B
