This year Rachel watched 60 movies. She thought that 57 of them were very good. Of the movies she watched, what percentage did she rate as very good?

Answers

Answer 1

Answer:

95%

Step-by-step explanation:

The percentage that Rachel rated as very good is calculated as:

The number that she thought was very good/ Total number of movies × 100

The number that she thought was very good = 57 movies

Total number of movies = 60 movies

Hence,

57/60 × 100

= 95%

The percentage that Rachel rated as very good is 95%

Answers

The answer is B. -8x + 66

Make x the subject of the formula where x is positive
b= x -6 / x + 2

Answers

Answer:

[tex]b = \frac{x - 6}{x + 2} \\ b(x + 2) = x - 6 \\ bx + 2b = x - 6 \\ bx - x = - 6 - 2b \\ x(b - 1) = - 2(3 + b) \\ x = \frac{ - 2(3 + b)}{b - 1} [/tex]

Charles and Wilma have different internet providers. Charles pays $0.25 per gigabyte of data. Wilma pays a flat fee of $20 and $0.05 per gigabyte. How many gigabytes of data must each use for Charles' internet bill to equal Wilma's internet bill?

Answers

Answer:

We want to find the point where these two lines intersect:

Equation for Charles: y=0.25x

Equation for Wilma: y=0.05x+20

0.25x=0.05x+20

0.2x=20

x=100

So, Charles must use 100 gigabytes of data to equal Wilma's internet bill.

Let me know if this helps!

The number of gigabytes of data that must be used for Charles' internet bill to equal Wilma's internet bill is; 100 gigabytes

What is the Intercept of the equations?

Let the amount of gigabyte of data be x.

Since Charles pays $0.25 per gigabyte of data, then the equation for Charles is; y = 0.25x

Wilma pays a flat fee of $20 and $0.05 per gigabyte and as such the equation for Wilma is; y = 0.05x + 20

For Charles' internet bill to equal Wilma's internet bill, Thus;

0.25x = 0.05x + 20

0.2x = 20

x = 20/0.2

x = 100

Thus, Charles must use 100 gigabytes of data to equal Wilma's internet bill.

Find each value or measure. Assume that segments that appear to be tangent are tangent. Find QS

Answers

Answer:

arc QS = 104°

Step-by-step explanation:

arc QTS = 2(128) = 256

arc QS = 360 - 256 = 104°

The measure of arc length QS is 104.

We have,

An inscribed angle is an angle whose vertex is on the circumference of a circle, and its sides are chords of the circle.

From the definition,

Inscribed angle = 1/2 x intercepted arc

Now,

128 = 1/2 x QTS

QTS = 256

Now,

QTS + QS = 360

256 + QS = 360

QS = 360 - 256

QS = 104

Thus,

The measure of QS is 104.

1. Divded 35 by 14 and u get 0.4

Divided 40 by 0.4 and u get 100

Answer:

Step-by-step explanation:

You could solve it two ways:

Cross multiply:

x times 35 = 35x

40 times 14 = 560

35x divided by 35 = x

560 divided by 35 = 16

x = 16

Or:

35 divided by 14 = 2.5

40 divided by 2.5 = 16

x = 16
