Answer:
31/4
Step-by-step explanation:
Leave the 7 alone for now.
0.75 is equal to 75/100
so now simplfy 75/100=3/4
now add the 7 back in
its
7 and 3/4
That can be your final answer or you can make it improper by multiplying 4 * 7 + 3
that gives you 31 and add the 4 back which is 31/4
3 × 3 = 9
4 × 4 = 16
5 × 5 = 25
So, the perfect squares between 6 and 31 is :
{9, 16, 25}
Answer:
For 13: 13/30
Step-by-step explanation:
First simplify!
9x - 25 + 21x - 35 + 12 = 0
then simplify some more
9x + 21x = 30x
(-25) + (-35) + 21 + 12 = -13
30x - 13 = 0
now add 13 to both sides, 13 and -13 cancel each other out and it becomes
30x = 13
then you divide by 30 to get x by itself. 30 cancels itself out and you are left with 13/30 which doesn't simplify so that shod be your answer! I couldn't figure out 14 but I hope this helps!!!
Answer:
a
Step-by-step explanation:
A is the answer, since when you graph it, you are able to visualize y crossing -2 and x crossing 3.
Answer:
16.2 m
Step-by-step explanation:
First, we can draw a picture. The cable goes from the top of the pole to the ground (with the pole on the right in my drawing), and the point on the ground is 10 m away from the base of the pole. This forms a right triangle, with the right angle being between the 10 m distance and the pole itself. We can then apply the Pythagorean Theorem, so
a²+b²=c², with c being the side opposite the right angle (the cable), getting us
10²+(length of pole)² = 19²
19²-10²=(length of pole)²
= 261
square root both sides to isolate the length of the pole
length of pole ≈ 16.2 m
