Answer:
Equation: r-20=74
Step-by-step explanation:
So he started with 94. I got B
Use trigonometry.
cos(18°) = x/25
Multiply both sides by 25.
cos(18°)25 = x
23.7764129074 = x
We round off to the nearest hundredth. This means to round off to two decimal places.
Doing so, we get 23,78 cm = x.
1/3 * 9x = 3x
1/3 * 3 = 1
3x + 1 = 4x
3x + 1 = 4x
4x=4x
Answer:
300 cm^2
Step-by-step explanation:
The volume of the rectangular prism is calculated by multplying lenght to the widht to the height
20*15*10 = 300 cm^2
The linear equation for the number of cookies he receives, for x hours practicing the piano, is:

A <u>linear function</u> has the format given by:

In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- We have two points: (5,15) and (10,20).
- The slope is given by <u>change in y divided by change in x</u>, then:

Then

Point (5,15) means that when
, which is used to find b.


The, the function is:
