8 groups of 4 boys and add 7 girls to the groups
Answer:
62.83 cm squared
Step-by-step explanation:
A = 2πrh+2πr^2
A = 2π(2)(3)+2π(2)^2
A = 2π(6)+2π4
A = 12π+8π
A = 20π
A = 20(3.14)
A = 62.83 cm squared
Answer: Very Easy 3/5 x 7 = 4.2. The decimal 4.3 can be written as the mixed fraction 4 3/10 or as the improper fraction 43/10.
Answer:
10 feet
Step-by-step explanation:
Given that the distance to be reached is 8 feet above ground and she she placed a ladder so that it reached the bottom of the window, the base of the ladder was 6 feet from the house, the length of the ladder considered with the other lengths forms a right angled triangle.
The length of the ladder represents the hypotenuse side hence using pythagoras theorem
F^2 = 8^2 + 6^2
where F is the length of the ladder in feet
F^2 = 64 + 36
= 100
find the root of both sides
F = 10 feet
The ladder is 10 feet long

Answer: Choice C</h3>
============================================================
Explanation:
Let's solve the first inequality for p
4p+1 > -7
4p > -7-1
4p > -8
p > -8/4
p > -2
And we'll do the same for the second inequality as well
6p+3 < 33
6p < 33-3
6p < 30
p < 30/6
p < 5
----------------------
We've found that p > -2 and p < 5
This must mean -2 < p < 5
The graph of which consists of open holes at -2 and 5 on the number line, then we shade in between those open holes. The open holes are to indicate "do not include the endpoint as part of the shaded solution set".
We can say that p is between -2 and 5, excluding both endpoints.
So that's why graph C is the final answer.
