Hello!! I need help with square root please help me!!!

Answers

Ok so what you need to do is you need to get all the numbers and see which one is the right number so...

A. y = 11.2 that is wrong

B. y = 25 is wrong

C. y = 5 is right

D. y = 15 is wrong.

C is right because it would be 5 times 5 times 5. SO 5 times 5 is 25, and then u times it by 5 and you get 125!

C is correct

Hope this helps!!

Answer:

This is actually a cube root, since you need a cube root to cancel out the cube.

C, y = 5

Step-by-step explanation:

125 = 5 × 5 × 5 = 5^3

5 × 5 × 5 = 25 × 5 = 125.

Therefore the cube root of 125 = 5.

It REALLY helps when you break these into factors.

[tex] \sqrt[3]{125} = 5 , \: as \: {5}^{3} \: = 125 [/tex]

This is essentially asking what multiplied by itself three times is equal to 125.

Process of elimination can be used for any number cubed that is ≠ 125

i.e : 11.2^3 ≠ 125

11.2^3 = 11.2 × 11.2 × 11.2 = (11.2-1.2)(11.2+1.2)(11.2) = (11.2)((10)(12.4) + 1.2^2) = 124 + 1.44 = (125.44)(11.2) = 125.44(10+1+(2/10)) = 1254.4 + 125.44 + 25.088 = 1404.928 ≠ 125, y ≠ 11.2

I.e : 25^3 = 25 × 25 × 25 = 625 × 25 = (600+25)(25) = 625 + 6(25)(100) = 15000 + 625 = 15625 ≠ 125, y ≠ 25.

And i.e: 15^3 = 15 × 15 × 15 = 225 × 15 = (225)(10+5) = 225(10) + 225(10/2) = 2250 + 2250/2 = 2250 + 1125 = 3375 ≠ 125, y ≠ 15.

Step-by-step explanation:

That red line is on the negative side of the x-axis and since all the numbers are 7 I'm just gonna assume that its a negative 7. Good luck sugar plum ;)

Answer: Not lying cause what's the point of lying to someone asking for help. The answer is x = -7

Step-by-step explanation:  X= -7 because if you look at a graph with negative and positive on it along with the Y and the X on it. Then you'll see that the middle of the plus is zero the left of the middle (going down the X axis) is negative. And the right side of the X axis is positive and the line is on the negative side of the X axis. That's why instead of it being Y= -7 ( which is NOT the answer) is wrong because the line is over the X axis instead of the Y axis.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Point S is between points R and T on RT.

RS = 2x - 8

ST = 3x - 10

RT = 17

From the above information:

RT = RS + ST

17 = 2x - 8 + 3x - 10

17 = 5x - 18

35 = 5x

x = 35/5

x = 7

RS = 2x - 8 = 2(7) - 8 = 6 units

ST = 3x - 10 = 3(7) - 10 = 11 units

RT = 17 units

Thus, the value of x is 7 and the measure of the line segment RS is 6 units, ST = 11 units, and RT = 11 units.

Answer:

Hey!

Your answer is 11cm!

Step-by-step explanation:

So to get the radius from the Circumference we need both the Circumference and the value of pi...3.14

Radius = [tex]\frac{C}{2\pi }[/tex] ... (that's the formula)

WE SUBSTITUTE IN:

Radius = 69.1/2 x 3.14

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Jacinda = 16 baskets

Greta = 4 baskets

The number of baskets Jacinda made is how many times more than the number of baskets Greta made?

To obtain this :

Number of baskets Jacinda made / Number of baskets Greta made

If Jacinda's basket = J ; Greta's basket = G

J / G

16 / 4 = 4

Hence, Number of basket Jacinda made is 4 times more than that made by Greta

2. One action figure sells for $3.50 How many action figures can Sergio buy for $20.00?​

Answers

Answer:

He can buy 5

Step-by-step explanation:

To find the answer, you have to do divide 3.50 and 20. You get 5.714285714. You can't round up, since you are dealing with money, so round down to 5.

Hope this helps :)

Step-by-step explanation:

One action figure can be shown as x so x=$3.50.

Sergio has $20.00 so the equation is 20.00÷3.50 = number of x's Sergio can buy.

20÷3.50 =5 2.5/3.5

So x=5 2.5/3.5

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

Given;

Gianna walked 12 miles in 6 hours

6hours= 12 miles

1hour= 12/6miles

1hour= 2miles

Therefore, the rate of gianna by unitary will be 2mph

Ice lobes were dynamic tongues of ice that extended far south of the main ice sheet and in contrast to the glacial ice sheet that moved slowly, ice lobes advanced quickly and then stopped. Elaborate on how such an ice lobe may be responsible for the formation of the Minnesota River. A) The ice lobes advanced and stopped many times, eroding the land to create a trough and then filled it with draining water from the ice sheet that was feeding them. B) There was no true drainage valley for the melting glaciers and multiple small streams flowed from north to south. Eventually they merged, forming the Minnesota River. C) Beneath the till of the Des Moines ice lobe lie layers of older glacial units from previous glaciations; these layers vary in thickness and when they melted, formed the Minnesota River. D) Outwash plains contained large amounts of glacial till that eroded the land and one area was the trough of the Minnesota River. Eventually the waters of the outwash plain filled the trough.
