Answer:
Yes, he will have enough 3 over 8 ft pieces for his class.
Step-by-step explanation:
Given:
Number of wood required = 22
Length of each wood,
Total length of the board,
Therefore, the number of woods that can be made using the given board is given as:
So, he can make 24 woods of length using the 9 ft board. But he has to make only 22 pieces.
Therefore, he has enough of the wood to make the required number of pieces.
Answer:
#1 x<-14 #2 x> 1/2 (hope you get a good grade)
Step-by-step explanation:
Answer:
8 Liters
Step-by-step explanation:
Percentage of Alcohol in water= 2L X 0 =0
Percentage of Alcohol to be added = xL X 0.9 =0.9x
- New Volume =(x+2) Liters
- Desired Concentration = 0.72%
Therefore:
0+0.9x=0.72(x+2)
0.9x=0.72x+1.44
Collect like terms
0.9x-0.72x=1.44
0.18x=1.44
Divide both sides by 1.44
x=8 Liters
Therefore, Shanice must add 8 Liters of 90% alcohol solution to create the desired mixture
Answer:
8 39/40
Step-by-step explanation:
7/8+8 1/10
35/40 + 8 4/10
8 39/40
The option that best describes the graphed function is: D. inverse variation; k = 4
<h3>What is an Inverse Variation?</h3>
Given two variables x and y has an inverse variation, the equation that models the relationship of the inverse variation is: y = k/x, where k = xy.
This means that as x increases, y decreases. This is the same for the graph given. So, it is an inverse variation.
When x = 2, y = 2. Therefore:
k = (2)(2)
k = 4
