Solve for x.3-sqrt(x)=0 What is the root? If there is none, choose none. x = 3 x = 9 none

Kryger [21]

Answer:

Step-by-step explanation:

3-sqrt(x)=0 should be rewritten as 3 = sqrt(x) or sqrt(x) = 3.

To obtain the value of x that satisfies this equation, square both sides:

x = 3^2, or x = 9.

Solve the formula t= 4u/e, for the variable e

Komok [63]

Answer:

$e=4u/t$

Step-by-step explanation:

we have

$t=\frac{4u}{e}$

Solve for the variable e

That means -----> Isolate the variable e

Multiply by e both sides

tex](e)t=\frac{4u}{e}(e)[/tex]

$et=4u$

Divide by t both sides

$e=4u/t$

Suppose you have a bag of red, blue, and yellow marbles. If the probability of picking a red marble is1/6 and the probability of

yulyashka [42]

The probabilities of picking a red, blue, and yellow marble must be equal to 1. so

P(R)+P(Y)+P(B)=1

1/6+1/2+P(B)=1 making all terms have a common denominator of 6 we have:

1+3+6P(B)=6

4+6P(B)=6

6P(B)=2

P(B)=2/6

P(B)=1/3

Jacklynn wondered how much of the moon covers if half of the moon is shaded. She learned in Science Class that the moon has radi

Lesechka [4]

Answer:

6.3 × 10⁶ square miles

Step-by-step explanation:

We are given,

The radius of the moon is approximately 1000 miles.

We know that the moon resembles a sphere and also,

Area of sphere = $4\pi r^{2}$ , where r is the radius.

Now, the area of the moon = $4\pi 1000^{2}$ = 1.26 × 10⁷ square miles

Since, only the half of the area is clear to view.

So, the area left to view = $\frac{1.26\times 10^7}{2}$ = 6.3 × 10⁶ square miles.

Hence, the area of the moon in view is 6.3 × 10⁶ square miles.
