Answer:
x=70
Step-by-step explanation:
x/10=7
First you need to get the x by itself, so you should do the opposite of what is happening to the x.
In this case the x is being divided so you would need to multiply.
So multiply the x by 10 and this gets it by itself.
But you have to do to one side what you do to the other.
So multiply the other side by 10 as well!
This equals x=70
To show work on both sides, show the multiplication of both sides by 10
Answer:
The height of the rocket at 3 seconds is 270 feet
Step-by-step explanation:
To calculate the height of the rocket at 3 seconds,
First, we will determine the height the rocket has traveled in 3 seconds
The height traveled by the rocket is given by
Height (h) = Velocity (v) × Time (t)
From the question,
The rocket travels 85 feet per second, that is the velocity of the rocket is 85 feet per second,
Now,
v = 85 feet / second
t = 3 seconds
Hence,
Height (h) = 85 feet /second × 3 seconds
Height = 255 feet
∴ the rocket would have traveled 255 feet in 3 seconds,
But, the rocket starts on a launch pad 15 feet of the ground,
Then, the height of the rocket at 3 seconds is
255 feet + 15 feet = 270 feet.
Hence, the height of the rocket at 3 seconds is 270 feet

Answer:
Step-by-step explanation:
First, you gotta work out the hypotenuse of ABC, which is AC.
To do that, you need to figure out the scale factor between the two right-angled triangles. You can do that for this question because this is a similar shapes question.
12.5/5 = 2.5
The scale factor length between the two triangles is 2.5.
You can use 2.5 now to work out AC, so AC would be 13 x 2.5, which gives 32.5.
Now that you've got the hypotenuse and BC of ABC, you can use Pythagoras's theorem to work out the length of AB
Pythagoras's theorem = 
a = BC = 12.5
b = AB = we need to work this out
c = AC (the hypotenuse we just worked out) = 32.5
Let's both simplify and rearrange this at the same time so that we have our b on one side.
= 1056.25 - 156.25
b = 
b = 
b = AB = 30 We've found b or AB, now we can work out the perimeter of ABC.
Perimeter of ABC = AB + BC + AC
= 30 + 12.5 + 32.5
= 75 Here's the perimeter for ABC.
