Step-by-step explanation:
1)X represents the time he spent in cardio.
Y represents the time he spent in weighted.
2)If you could put the options on the second one it would be better.
3)4x+y=210
3x+2y=195
y=210-4x
3x+2(210-4x)=195
3x+420-8x=195
5x=420-195
5x=225
x=45
y=30
Total time of one cardi and weighted = 75min= 5/4 h.
4)2x+4y=
90+120=210 total time of week three.
Answer:
62.8 square inches
Step-by-step explanation:
we know that
To find out how many square inches of space the rolling pin comes in contact with after one complete roll, determine the lateral area of the rolling pin
The lateral area of a cylinder is given by the formula
we have
substitute
Answer:
8
24
3
yes
Step-by-step explanation:
the original area of the figure is 4 · 2 which equals 8.
Since the dilation that is needing to be done is by a scale factor of 3 then all we need to do is multiply the original area by 3, which gives us the new area 24.
So because the only transformation was a dilation that didn't significantly change the figure then we can say that both figures are similar.
Answer: 3.7 percent is the answer
Step-by-step explanation:
The answer is A.
I used the formula for finding the vertex of a parabola and I got the first answer choice. So A is correct. :)
