Answer:
The asnwers for your two question problem are
1. $625
2. 90 building blocks
Step-by-step explanation:
First problem
The fabric Josef is using comes in 100 square-inch pieces that cost $6.25 each. What will his fabric cost?
* The fabric has 100 pieces
* Each piece costs $6.25
Total amount for the fabric = $6.25*100 = $625
Second problem
A student made a toy chest for his baby sister's square building blocks. Six layers of blocks can fit in the box, and each layer has 15 blocks. How many building blocks can the toy chest hold?
* 6 layers of blocks fit in the box
* Each layer has 15 blocks
Total amount of blocks = 6*15 blocks = 90 blocks
Answer:
18 inches
Step-by-step explanation:
Applying,
Pythagoras theorem,
a²= b²+c²
Where a = hypotenus, b = base of the triangle, c = height.
make c the subject of the equation
c = √(a²-b²)................. Equation 2
From the diagram attached,
Given: a = 36 in, b = (36/2) in = 18 in
Substitute these values into equation 2
c = √(36²-18²)
c = √(1296-324)
c = √(972)
c = √(972)
c = √(324×3)
c = 18 inches
Answer:
36.2 is the answer
Step-by-step explanation: 10% of 136 is 13.6 times 2.5
Answer:
p(4 successes) ≈ 7.7%
Step-by-step explanation:
p(k successes in n trials) = C(n,k)·p^k·(1-p)^(n-k)
You have n=5, k=4, p=0.4, so the probability is ...
p(4 successes) = C(5,4)·(0.4)^4·(1 -0.4)^1 = 5·0.4^4·0.6 = 0.0768
p(4 successes) ≈ 7.7%
Answer:-7/31
