Solve 64x2 - 121 = 0 using square roots.
Using the square root property to solve this 64x² - 121 = 0, the value of x is - 11 / 8 and 11 / 8.
How to solve quadratic equation using square root property?64x² - 121 = 0
add 121 to both sides of the equation
64x² - 121 + 121 = 0 + 121
64x² = 121
divide each term by 64 and simplify
64x² / 64 = 121 / 64
x² = 121 / 64
Take the square root of both sides of the equation to eliminate the exponent on the left side
√x² = ±√ 121 / 64
Simplify the right side of the equation.
x = ± 11 / 8
Therefore,
x = 11 / 8, - 11 / 8

Step-by-step explanation:
You use a "centroid." There is a ratio. As provided, MW is 9. The ratio is 1:2, and CW is smaller. The answer is 3.
"The centroid is also known as the geometric center of the object. The centroid of a triangle is the point of intersection of all the three medians of a triangle. The medians are divided into a 2:1 ratio by the centroid." -cuemath .com > geometry > centroid-of-a-triangle
Each railroad car in a train set is 6 inches in length.the railroad track is 5 feet long .how many railroad cars can fit on the track
Answer: 10 cars
Step-by-step explanation:
We know that:
A railroad car is 6 inches long and the railroad track is 5 feet long
Start by converting feet to inches. You can do that by multplying the amount of feet by 12.
5 feet x 12 = 60 inches
Now we can divide the length of the railroad track by the length of the railroad cars to see how many we can fit.
60 ÷ 6 = 10

Sonnie deposited $2,500 into an account that earns simple interest. After 5 years, she earned $375 in interest. What was the interest rate of the account?
Answer:
3%
Step-by-step explanation:
The interest on the account is given by the simple interest formula:
I = Prt
where I is the interest, P is the principal invested, r is the annual rate, and t is the number of years
375 = 2500r(5) . . . . . . using the given values in the formula
375/12500 = r = 0.03 . . . . . divide by the coefficient of r
Sonnie's account had a 3% interest rate.

Y is
inversely proportional to the square of x.
The Given that y = 10 for a particular value of X,
find the value of y
when this value of x
is halved.
Answer:
y = 40
Step-by-step explanation:
y = k/x²
Let a = the x-value corresponding to y = 10
For x = a, y = 10
10 = k/a²
k = 10a²
The function is:
y = 10a²/x²
Now we halve the x-value a:
Let x = a/2.
y = 10a²/x²
y = 10a²/(a/2)²
y = 10a²/(a²/4)
y = 40

Solve for Y. Will mark branliest please help!
Answer:
y = 2 v2, 2 square root 2
Step-by-step explanation:
since it's a right triangle with a 45°, that means the other angle is also 45°
which makes both sides the same
Pythagoras
4^2 = y^2 + y^2
16 = 2 y^2
16/2 = y^2
8 = y ^2
v8 = y
2 v2 = y

Answer:
[tex]2\sqrt{2[/tex]
Step-by-step explanation:
The ratios of a 45 - 45 - 90 triangle is [tex]1:1:\sqrt{2}[/tex]
To get 4 for the hypotenuse, you need to mulitpy [tex]\sqrt{2}[/tex] by [tex]\sqrt{8}[/tex].
[tex]\sqrt{2}[/tex] x [tex]\sqrt{8}[/tex] = [tex]\sqrt{16}[/tex]
Simplify.
[tex]\sqrt{16} = 4[/tex]
If you simplify the [tex]\sqrt{8}[/tex], it equals [tex]2\sqrt{2}[/tex].
Since the ratio is [tex]1:1:\sqrt{2}[/tex]
The sides will be [tex]2\sqrt{2}:2\sqrt{2}:4[/tex]
