Answer:
7
Step-by-step explanation:
Total number of surfaces of cube are 6.
Each surface is square.
And area of square is (side)^2
That means, total surface area will be 6 * (side)^2
From question,
294 = 6 * (side)^2 ( Surface area given)
=> 294 ÷ 6 = ( side) ^2
=> 49 = side^2
=> √49 = side
=> 7 = side
So, length of edge of cube is 7
Step-by-step explanation:
In 1 second Fran cycles 5.3 m.
So we need to work out how many seconds is in 5 minutes.
1 minute = 60 seconds
5 minutes = 60*5 = 300 seconds
So Fran cycles at a speed of 5.3 m/s in 300 seconds.
1 second = 5.3m
300 seconds = 5.3*300 = 1590m
Hope this helps!
Answer:
h(-4) = -4
Step-by-step explanation:
Since x is given (x = -4). Then, all you need to do is log in -4 for each value of x
h(-4) =
−
(
−
4
)
2
-3(-4)
h(-4) = -(16) + 12 = -4
Twice a number (2x) decreased by 7 (- 7).
2x - 7
Two times a specfic number (x) subtracted by 7.
The answer is 19.4
Most of the time when you try to find a missing length of a right triangle you use Pythagorean theorem. Pythagorean theorem is A squared plus B squared equals C squared. C squared is always going to be the longest length/diagonal line otherwise known as your hypotenuse. In this case the ladder is the hypotenuse. So instead of adding five squared +20 squared you’re going to square 20 and then subtract five squared to get the missing length which would be B squared and then you have to find the square root of B squared. So 20 squared is 4000. 5squared is 25 400-25 = 375 square root of 375 is about 19.4.
