Since the value inside of the square roo should be absolute value as negative numbers make the function complex.
a = h/b, solve the formula for b
a = h/b
x b, both sides
ab = h
÷a
b = h/a
B = h/a
Hope this helps!
Answer: b = h/a
Step-by-step explanation: What you need to do is to get b by itself and to do that you have to move b to the other side because it's being divided by b. To do that you multiply by b on both sides.
1) ab = h
Now, isolate b by dividing a into both sides.
2) b = h/a
Now, you have b alone you know what b is equal to.

Answer: 124.3%
Step-by-step explanation:

1.24296875*100=124.296875
124.296875=124.3%
Since 318.2 is greater than 256, the percent is going to be greater than 100, because the number 318.2 is more than 100 of 256 which basically translates to 318.2 being greater than 256.

Answer:
(- 2, 3 )
Step-by-step explanation:
6x + 2y = - 6 → (1)
3x - 4y = - 18 → (2)
multiplying (1) by 2 and adding to (2) will eliminate y
12x + 4y = - 12 → (3)
add (2) and (3( term by term to eliminate y
15x + 0 = - 30
15x = - 30 ( divide both sides by 15 )
x = - 2
substitute x = - 2 into either of the 2 equations and solve for y
substituting into (1)
6(- 2) + 2y = - 6
- 12 + 2y = - 6 ( add 12 to both sides )
2y = 6 ( divide both sides by 2 )

.A rancher divided his land into square sections. One large section has an area of 112 square
miles. To the nearest tenth of a mile, what is the length of one side of this tract of land?
To the nearest tenth of a mile, the length of one side of this tract of land is 0.64 miles
This problem can be solved by using the concept of scale factor. Scale factor is useful in finding proportional measurements.
Proportion implies having the same ratio.
Scale factor can be defined as the ratio of the measurement of the model to the measurement of the actual form in the simplest form. In other words, the ratio of any two corresponding lengths in two similar geometric figures is called a scale factor.
If the scale factor is more than 1, that is, scale factor > 1,
then it is an enlargement,
If the scale factor is less than 1, that is, scale factor < 1,
then it is a reduction.

Gordon invests $2,500 for 20 months at a simple interest rate of 12.4%. the amount of interest received is found by i=prt since r= 0.124. i=0.124 x p x t. what are p and t?
The p and t represent Principal and time and interest is 517.7
We are given the formula to find the interest. So, the formula is -
I = (PRT) ÷ 100
In this formula, I refers to interest, P refers to Principal, R refers to rate of interest and T refers to time. Time will be in years and division by 100 is done for rate of interest.
Keep the values in formula to calculate the interest -
As per the known fact, 12 months = 1 year
So, 20 months = (1 ÷ 12) × 20
20 months = 1.67 years
Interest = (2500 × 12.4 × 1.67) ÷ 100
Performing multiplication in numerator
Interest = 51,770 ÷ 100
Performing division to find the interest
Interest = 517.7
Hence, p refers to principal and t refers to time. The interest that Gordon will receive will be 517.7.

A guardrail's acceptable height range is 99cm to 113cm and the definite absolute value inequality is as follows | h - 106cm | ≤ 7cm,
How to define an inequality? A statement stating that one quantity is less than or (greater than) another.An inequality solution is a number that, when replaced for the variable, makes the inequality true.We understand that the height must be 106cm with a maximum absolute deviation of 7cm.
As a result, the maximum height is:
106cm plus 7cm = 113cm
The bare minimum is:
99cm = 106cm -7cm

2x+4=3x-2 solve for x
Answer:
x = 6
Step-by-step explanation:
2x + 4 = 3x - 2
2x - 3x = -2 - 4
-x = -6
x = 6
Answer:
x = 6
Step-by-step explanation:
We are given this equation:
2x + 4 = 3x - 2
And we want to evaluate the equation for x.
To do this, we need to isolate the variable (x) on one side of the equation.
We can start by putting the numbers on one side.
We can subtract 4 from both sides of the equation to start. Remember that when solving equations, whatever we do on one side of the equation, we need to do it on the other side as well.
2x + 4 = 3x - 2
-4 -4
___________________
2x = 3x - 6
Now, let's put the variables on the other side.
Subtract 3x from both sides.
2x = 3x - 6
-3x -3x
______________
-x = -6
Now, the numbers and variables are on different sides, however we are not done yet, as we need to take care of the negatives, as x shouldn't be negative in this case.
-x is the same as -1x, or -1 * x.
So, in order to get rid of the negatives, we can either multiply or divide both sides by -1.
Let's multiply both sides by -1.
-1(-x) = -1(-6)
x = 6
The value of x is 6.
