Morgan saw 12 blue, 18 red, and 40 white cars drive by her house in 1 hour. What is the experimental probability that the next car that drives by her house will not be a white car? Round to the nearest hundredths.
Answer:
0.7 or 1 rounded to the whole number
Step-by-step explanation:
Add all of the numbers together (12+18+40=60)
And make your total as a fraction
There were 42 white cars and the total was 60 so the answer would be [tex]\frac{42}{60}[/tex] or 0.7 simplified (42 ÷ 60)

Answer:
1. m∠1 = 105 m∠2 = 75
2. x= 130
Step-by-step explanation:
1. Solved m∠2 by using 75° angle because they are the same angle
m∠1 = 180- 75°
2. 180-70= 110
(x-20)= 110
x= 130

In Britain a Value Added Tax (VAT) of 17% is added to most purchases. If a skit costs $58.50 including tax, what is the price of the skirt before tax?
Answer:
i think it is 45.70
Step-by-step explanation:
Answer:
$48.55
Step-by-step explanation:
Make 17% into a decimal Multiply 0.17 and the number of Britain Value including tax Then take that number and subtract it by the number of Britain Value including taxEquation:
17% = 0.17
Why? The symbol % is called the percent sign. The expression 17% means 17 parts out of 100. Therefore, 17% is equivalent to the common fraction and to the decimal fraction 0.17.
0.17 × (Britain Value Including Tax) 58.50 = 9.945 to be exact but I rounded it up to 9.95 for easier use
58.50 - 9.95 = 48.55
So $48.55 is your answer
I hope this helped! Brainliest highly appreciated! Tell me if this is wrong I would like to know :) All of this written and solved by me. Except for the italic explanation of how to make 17% a decimal. You are free to use this explanation if needed so don't feel hesitant to copy and paste this.

A carpenter attaches a piece of plywood with a width of 4 feet and a length of p to another piece of plywood that has a width of 4 feet and a length of 8 feet.
Which expression represents the area of the combined piece of plywood?
A. 4(p + 8)
B. 8(p + 4)
C. 8(p + 8)
D. 4(p + 4)
4p + 32, or option C, is the term that depicts the combined plywood piece's area.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
When the two pieces of plywood are attached, the width of the combined piece remains 4 feet.
The length is the sum of the length of the two pieces. So, the area of the combined piece is the product of the length and width.
Length of combined piece = p + 8 feet
Width of combined piece = 4 feet
Therefore, the area of the combined piece of plywood is:
Area = length × width
Area = (p + 8) × 4
Area = 4p + 32
So, the expression that represents the area of the combined piece of plywood is 4p + 32, which is option C.

Once again, first you ant to simplify the equation before putting in the numbers. So the simplified equation is mh + mp -p/h +m. Then you put the numbers in. mh is actually 3(-1), which is -3. mp is really 3*4, which is 12. p/h is 4/-1, which is -4, and then you add m. So when you put the numbers is it ends up as -3 + 12 - 4 +3, which simplified is 8, or C
