Teo spins the spinner 120 times. He expects to land on one particular color 30 times. What color is it?

olasank [31]

Answer:

Red

Step-by-step explanation:

P = 30/120 = 1/4

The spinner is divided into 8 equal sections. 1/4 of 8 is 2. So we're looking for a color that appears on exactly 2 of the sections.

The color is red.

Jackie has $33, and needs to get a taxi. The cost for a taxi is a fee of $5, plus $7 per mile. Which inequality would help Jacki

Rus_ich [418]

Answer:

$5 + 7x \le 33$

Step-by-step explanation:

Given

$Base\ Charge = 5$

$Additional = 7$ per mile

$Total = 33$

Required

Determine the inequality

First, we need to determine the total cost for x miles.

$Cost = Base\ Charge + Additional * x$

$Cost = 5 + 7 * x$

$Cost = 5 + 7x$

The total cost can not exceed the amount he has, so the inequality is:

$Cost \le Total$

$5 + 7x \le 33$

What is the solution to the equation below? √x - 4 = -2 O A. X=& O B. X=4 X = 4 C. x = 6 D. X = 2

saul85 [17]

Answer:

x = 4

Explanation:

Given the expression;

$\sqrt[]{x}-4\text{ = -2}$

Add 4 to both sides

$\begin{gathered} \sqrt[]{x}-4+4\text{ = -2+4} \\ \sqrt[]{x}=\text{ 2} \end{gathered}$

Square both sides

$\begin{gathered} (\sqrt[]{x})^2=2^2 \\ x\text{ = 4} \end{gathered}$

Hence the value of x is 4

L is the midpoint of line segment KM. If KL = 2x - 3 and LM = x + 7. find the value of x.

tatyana61 [14]

Answer:

x = 10

Step-by-step explanation:

Since L is the midpoint

KL = LM

2x-3 = x+7

Subtract x from each side

2x-3-x = x+7-x

x-3 = 7

Add 3 to each side

x-3+3 = 7+3

x = 10
