x^2/3=12
Plz I need help with this ASAP, it’s solving quadratic functions by square roots by the way
Answers
Answer:
this is easy. all you have to do is multiply the denominator (3) by the outside number (12) to get 36. this leaves the equation being x^2 = 36. now you just find the square route of 36 (which is 6).
Step-by-step explanation:
x^2/3 = 12
12 x 3 = 36
x^2 = 36
/36 = 6
x = 6

Volume of a cylinder = area of base x height:
50.24 x 3 = 150.72 ft^3
Answer:
150 ft³
Step-by-step explanation:
base = circle..................base area = area of the circle = πr².
to get the radius of the circle, we substitute from the formula.
let π be 3.142
3.142 × r² = 50.24.............................. 3.142r² = 50.24
divide both sides by 3.142 to get r² = 15.99....................find the square root of 15.99 to get r = 3.999.
VOLUME = πr²h
= 3.142 × 3.999 ×3.999 × 3 = 150.72 ft³

Solve. 1/2(4x + 2/5) = 4/5
Answers
Answer:
[tex]\frac{1}{2}(4x + \frac{2}{5} ) = \frac{4}{5}\\2x + \frac{1}{5} = \frac{4}{5}\\\frac{10x + 1}{5} = \frac{4}{5}\\10x + 1= 4\\10x = 3\\x = \frac{3}{10}[/tex]
Answer:
x = 3/10
Step-by-step explanation:
Given equation,
→ 1/2(4x + 2/5) = 4/5
Let's solve the problem,
→ 1/2(4x + 2/5) = 4/5
→ 2x + (1/5) = 4/5
→ 2x = (4/5) - (1/5)
→ x = (3/5) × (1/2)
→ [ x = 3/10 ]
Thus, the value is 3/10.
Find the value of two numbers if their sum is 19 and and their difference is 5
Answers
Answer:
7 and 12
Step-by-step explanation:
x - y = 5
y = (5+x)
x+ (5+x) = 19
2x +5 = 19
2x = 14
x = 7
19-7 = 12
12 +7 = 19
12-7 = 5
if a + b =19
then, a - b =5
so, a= b + 5
if, a = b + 5
then, b + b + 5= 19
(2b) + 5 =1 9
19- a(5)= 14
b= 7
a+7=19
a= 12

The width of the TV will be equal to 16.49 inches.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.
Given that a certain television is advertised as a 21-inch TV (the diagonal length). If the height of the TV is 13 inches.
The width of the TV will be calculated as,
W = √ ( 21² - 13² )
W = √ ( 441 - 169 )
W = √272
W = 16.49 inches
Therefore, the width of the TV will be equal to 16.49 inches.

It is recommended that one fire extinguisher be available for every 4,520 square feet in a building. Write and solve an equation to determine x, the number of fire extinguishers needed for a building that has 88,140 square feet.
Answers
Answer:
There are 19.5 extinguishers needed.
Step-by-step explanation:
Given that,
One fire extinguisher be available for every 4,520 square feet in a building.
We need to find the value of x if the number of fire extinguishers needed for a building that has 88,140 square feet.
x = (Area of building)/(Area of one fire extinguisher)
So,
[tex]x=\dfrac{88140}{4520}\\\\x=19.5[/tex]
So, there are 19.5 extinguishers needed.

Nate is buying a new car. He will pay $2000 today and then $500 a month for x months.
Write an equation that can be used to find y, the total cost of the new car.
Answers
Answer:
y = 2000 + 500x
Step-by-step explanation:
2000 is the constant, because no matter how many months it takes for him to pay off the car, he has to pay the $2000 today.
And after he pays the 2000, every month he has to pay $500 until he pays the full price, so 500x stand for the months after he pays the initial $2000.
answer 2000 + 500 x M =y
