Answer:
294
Step-by-step explanation:
To find the surface area of a cube, first we need to realize that a cube, on its surface, is made up of 6 squares forming a box. That means that all we need to do is find the surface area of one of those squares, and multiply it by 6. So what we do is take side length 7, and square it, giving us 49. Then, we multiply that by 6 giving us 294. The formula for this, in short, is y=6a^2, y being the total surface area and a being a side length, in this case 7.

Answer:
the answer is 9.4
Step-by-step explanation:
9 4/10= 9+1/10
we know that 4/10 is the same as 4÷10.
therefor:
9 4/10=9+(4÷10)
then using long division for 4 divided by 10 we have:
=9+0.4=9.4

A pebble falls off of a cliff at a height of
2,304 ft. If the equation for height as a
function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the pebble
to hit the ground?
Answer:12
Step-by-step explanation: just did the assignment
The pebble will hit the ground after 12 seconds when the equation for height as a function of time is h(t) = -16t2 + initial height .
To find the time it takes for the pebble to hit the ground, we need to set the height function h(t) equal to zero and solve for t.
h(t) = -16t² + initial height
initial height = 2,304 ft
Setting h(t) to zero:
0 = -16t² + 2,304
Now, we can solve this quadratic equation for t.
-16t² + 2,304 = 0
Dividing both sides by -16:
t² - 144 = 0
Adding 144 to both sides:
t² = 144
Taking the square root of both sides:
t = ±12
Since time cannot be negative in this context, we discard the negative solution.
Therefore, the pebble will hit the ground after 12 seconds.

Give three ratios equivalent to 9:5
The proportions equal to the ratio 9 : 5 is given by the equation A = 18 : 10 , 27 : 15 and 36 : 20
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the equation will be
A = 9 : 5
Now , the proportion equivalent to the proportion A is given by
A = 9/5 be equation (1)
Multiplying the numerator and denominator by 2 , we get
A = 18/10
So , the value of A = 18 : 10
Now , Multiplying the numerator and denominator by 3 , we get
A = 27/15
So , the value of A = 27 : 15
Now , Multiplying the numerator and denominator by 4 , we get
A = 36/20
So , the value of A = 36 : 20
Hence , the proportion is 9 : 5
