make x subject of formula √x+a=b
Answer:
After making x the subject of the formula, the formula is:
[tex]x = (b-a)^2[/tex]
Step-by-step explanation:
Given formula is:
[tex]\sqrt{x} +a = b[/tex]
Making a variable subject of a formula or equation means that the variable has to be isolated in the equation to write it in terms of other variables and constants.
So,
In the given formula,
Subtracting a from both sides
[tex]\sqrt{x} +a-a = b-a\\\sqrt{x} = b-a[/tex]
The subject of the formula should not be in radical form.
Taking square on both sides
[tex](\sqrt{x})^2 = (b-a)^2\\x = (b-a)^2[/tex]
After making x the subject of the formula, the formula is:
[tex]x = (b-a)^2[/tex]

Jack paid off his loan in 10 years. If the amount paid off was $172,598 and annual interest rate was 3.25% compounded monthly. what was the original amount borrowed. Round to whole dollar
Answer:
$228,692
Step-by-step explanation:
10 years so 3.25% was added 10 times
3.25(10) = 32.5
32.5 + 100 = 132.5
So Jack paid 132.5% of his loan.
x/172,598 = 132.5/100
172598(132.5) = 22,869,235
22,869,235/100 = 228,692.35
Round it to the nearest dollar and you get 228,692
Determine the commission earned on $62,000 at a commission rate of 5%.
A commission of $3100 was earned on $62,000 at a commission rate of 5%.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Given that $62,000 is earned at a commission rate of 5%, hence:
Commission = 5% of 62000 = 0.05 * 62000 = $3100
A commission of $3100 was earned on $62,000 at a commission rate of 5%.

the value of a boat varies inversely with age. If a boat is worth $7000 when it is 3 years old, how much will it be worth when it is 7 years old
Step-by-step explanation:
let worth be y and age be x
y = k/x, where k is a constant, k ≠ 0
7000 = k/3
21000 = k
y = 21000/7
y = 3000
$3000

Then,
(2x+6)+(3x-25)+y= 180°
2x+3x+y=180-6+25

A football team carried out a report to see the impact of stretching on preventing injury. Of the 50 footballers in the squad 32 stretch regularly. Of those who stretch, 4 got injured last year. There was a total of 19 injured players last year.
The results can be presented in a frequency tree. What fraction of players who don't stretch get injured?
Using proportions, it is found that the fraction of players who don't stretch that get injured is: [tex]\frac{5}{6}[/tex]
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
From the data given, there are 50 - 32 = 18 footballers who do not stretch regularly, and of those 19 - 4 = 15 stretched, hence the fraction of players who don't stretch that get injured is:
[tex]f = \frac{15}{18} = \frac{5}{6}[/tex]

8 3/4 cups of flour
Step-by-step explanation:
So, we know that you need 5 pies and that each pie takes 1 3/4 cup. So basically all you have to do is come up with an equation, mine looks like
5 x 1 3/4 or 5 x 1.75 if you don't like fractions.
5 x 1 3/4 = 8 3/4

If two sides of a triangle measure 19cm and 34cm, check all possible values for the third side: HELPPPP ASAP!!!!
Answer: 13, 15, 21, 38, 52
because The total length of two sides of a triangle is always greater than the length of the third side => 34 + 19 > x
⇔ x < 53
=> x ∈ {13; 15; 21; 38; 52}
Step-by-step explanation:
All possible third sides of a triangle are;
⇒ x = 13, 15, 21, 38, 52
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Two sides of a triangle are 19 cm and 34 cm.
Now,
Since, The sum of two sides of a triangle is greater than the third side.
Let the third side = x
So, We can formulate;
x < 19 + 34
x < 53
Thus, All possible values of third sides are;
⇒ x = 13, 15, 21, 38, 52
