Answer:
A
Step-by-step explanation:
i think it is A because he should have solved it like this:
-2/3 * 5 1/6
-2/3 * 31/6 (convert mixed number into improper fraction)
-1/3 * 31/3 (cross reduction)
-31/9 (multiply fractions)
-3 4/9 (final reduction)
To find how many milliliters of iodine are in 1,000 mL of solution,we multiply the total volume by the percentage of iodine included:
1000×5%
=1000×0.05
=50mL
Thus the answer is 50mL.
Hope it helps!
Hello,
f(x)-2x-7
g(x)=-4x+3
(fog)(x)=f(g(x))=f(-4x+3)=-2(-4x+3)-7=8x-6-7=8x-13
(fog)(-5)=8*(-5)-13=-53
Answer:
Do not forgot to label axis.
Step-by-step explanation:
Attached below is a graph.
The length of the shorter piece of pipe is 47 inches.
<h3>How to find the length of the shorter piece?</h3>
A 235-inch pipe is cut into two pieces. One piece is four times the length of the other.
The length of the shorter piece can be found as follows:
let the length of the shorter piece be x.
Therefore,
length of the longer piece = 4x
Hence,
4x + x = 235
5x = 235
divide both sides of the equation by 5
5x / 5 = 235 / 5
x = 235 / 5
x = 47
Therefore,
length of the shorter piece = 47 inches.
