Answer:
We have 16 ounces of 3% H2O2
How many ounces of 30% H2O2 do we add to make a 10% H2O2 solution?
let x = amount of ounces of 30% H2O2 to add
.03 * 16 + .30x = .10 * (16 + x)
.48 + .30x = 1.6 + .1x
.2x = 1.12
x = 5.6 ounces

Answer: 64
Step-by-step explanation:
256 is thesame thing as 2 raise to power of 8.
We then multiply 2 raise to power 8 by the power of 3/4. We will then be left with 2 raise to power 6.
2 raise to power 6 equals:
= 2 × 2 × 2 × 2 × 2 × 2
= 64

Answer:
36 ft²
Step-by-step explanation:
Scale factor means the side length are multiplied by some value. Here, Jack takes 4 feet and multiplies it by a value of 1 1/2.
The side length he wants is one and a half times the length of his neighbor's.
The 'one' means the side length you started with, and the 'one half' means add half to the original length.
one and a half of four is six. (4 plus half of 4, which is 2, so 4 plus 2)
The box is square, so each side is 6 ft, so the area of the box is 6x6 = 36 ft²
Answer:
I think it's false.
In mathematics, a function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set.
6 has a relation to 5 and 10.
Answer:
Step-by-step explanation:
mean µ = 500
standard deviation σ = 100
Required P ( X < µ + σ )
= P ( X < 500 + 100 )
= P ( X < 600 )
= P [Z < (X - µ) / σ ]
= P [Z < (600 - 500) / 100 ]
= P [Z < + 1 ]
= .8413
In terms of percent the probability is 84.13 % .
