The probability that the spinner will land on 5 or 7 if the spinner is spun once is 1/4

<h3>How to determine the probability that the spinner will land on 5 or 7 if the spinner is spun once?</h3>

The sample space of the spinner is

S = {1, 2, 3, 4, 5, 6, 7, 8}

So, the sample size is

Size = 8

On the spinner, we have

n(5) = 1

n(7) = 1

The probability that the spinner will land on 5 or 7 if the spinner is spun once is calculated as:

P = P(5) + P(6)

This gives

P = 1/8 + 1/8

Evaluate

P =2/8

Simplify

P = 1/4

Hence, the probability that the spinner will land on 5 or 7 if the spinner is spun once is 1/4

The perimeter of a rectangle is 168 m. Its length is five times its width. Find the length and width.

almond37 [142]

Answer:

Length of rectangle = 63 m
Width of rectangle = 21 m

Step-by-step explanation:

Given: 

Perimeter of rectangle = 168 m
Length of rectangle is five times the width

To Find: 

Length and Width

Solution: 

Let's assume width of rectangle x m and length of rectangle be 3x m. To calculate the dimensions of the rectangle we will use the formula of Perimeter of the rectangle

Perimeter of rectangle = 2(L + B)

Substituting the required values:

→ 168 = 2(3x + x)

→ 168 = 2(4x)

→ 168/2 = 4x

→ 84 = 4x

→ 84/4 = x

→ 21 = x

Hence,

Length of the Rectangle = 3x = 3(21) = 63 m
Wdith of the rectangle = x = 21 m

Write the pair of fractions as a part of fractions with a common denominator 1/4 and 2/3

sladkih [1.3K]

Answer:

$\frac{3}{12} and \frac{8}{12}$ are the fractions with common denominator

Step-by-step explanation:

fractions are 1/4 and 2/3

$\frac{1}{4} and \frac{2}{3}$

To get common denominator we take LCD

LCD of 4 and 3 is 12

To get 12 in the denominator we multiply first fraction by 3 and second fraction by 4

$\frac{1*3}{4*3} and \frac{2*4}{3*4}$

$\frac{3}{12} and \frac{8}{12}$

Select the correct answer. What is the value of x in the given figure?

alexandr1967 [171]

Answer:

A. 8

Step-by-step explanation:

Since I'm rusty on this particular unit of Geometry, by following the patterns and definitions of congruence for tangents, I want to say that your answer is A, since both sides of the triangle should be congruent and equal, and since they're two apart, the other side shouldn't be different.
