Answer:
$75.26
Step-by-step explanation:
base cost = $49.95
total mile cost = 1.19*18 =$21.42
gas cost = $3.89
total cost =$(49.95 +21.42+3.89)=$75.26
The expression to represent total cost of the trip is $49.95 + $1.19m + (m/18)($3.89).
Given that, the rental has a base cost of 49.95, plus an additional cost of 1.19 per mile driven.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
If we let m = total distance, then we can set up an equation to find the total cost.
The additional cost for distance would be $1.19m
The cost for gas would be (m/18)($3.89)
So the total cost of the trip could be represented by $49.95 + $1.19m + (m/18)($3.89).
Therefore, the expression to represent total cost of the trip is $49.95 + $1.19m + (m/18)($3.89).

Mrs. Bailey had 12 pieces of candy. She gave away some candy and has 3 pieces left. What is the percent decrease of candy? PLEASE SHOW YOUR WORK. thank you
Mrs. Bailey had a 75% decrease in the number of candies she had after giving away 9 out of the original 12 pieces.
Explanation:To calculate the percent decrease of candy Mrs. Bailey had, we begin by identifying the initial amount and the final amount of candy. Mrs. Bailey started with 12 pieces and ended with 3 pieces, which means she gave away 12 - 3 = 9 pieces of candy. To find the percent decrease, we use the formula: “part over total, times one hundred, equals percent.” Here, the “part” is the amount of candy she gave away (9), and the “total” is the original amount she had (12).
The formula for the percent decrease is:
9 / 12 × 100 = 75%
So, the percent decrease in the number of candies Mrs. Bailey had is 75%.

the minute hand in a clock is 17cm long. find the area swept by it in 12 mins. the clock is a circle. no spamssssssssss pls
The area swept by the minute hand in 12 minutes is 181.58 cm²
Step-by-step explanation:
In the circle clock
The circumference of the circle is divided into 12 equal arcsThe central angle of each arc is 30°, because the measure of the circle is 360° and divided by 12 The central angle between each two consecutive hours is 30°There are 5 minutes between each two consecutive hours, then the central angle between each two consecutive minutes is 6° because 30° ÷ 5 = 6°When the minute hand is moved than the radius of the circle is the length of the minute handWhen the hour hand is moved than the radius of the circle is the length of the hour hand∵ The minute hand is swept by 12 minutes
∵ The central angle between each two consecutive minutes = 6°
∴ The central angle when the minute hand swept 12 minutes =
6 × 12 = 72°
∵ The area of a sector of a circle = [tex]\frac{x}{360}*\pi r^{2}[/tex] ,
where r is the radius of the circle and x is the central angle of
the sector
∵ The radius of the circle is the length of the minute hand
∵ The minute hand in a clock is 17 cm long
∴ r = 17 cm
∵ The measure of the central angle is 72°
∴ x = 72°
- Substitute these values in the rule of the area of a sector
∵ Area = [tex]\frac{72}{360}*\pi (17)^{2}[/tex]
∴ Area = 181.58 cm²
The area swept by the minute hand in 12 minutes is 181.58 cm²

Using only 32-cent and 20-cent stamps, Charlie put $3.36 postage on a package he sent to his sister,
He used twice as many 32-сent stamps as 20 cent stamps. Determine how many of each type of stamp
he used.
Answer:
Charlie used 4 20-cent stamps and 8 32-cent stamps.
Step-by-step explanation:
Let the number of 20 cents stamps be [tex]x[/tex]. Then, as per question, Chalie used twice as many 32-сent stamps as 20 cent stamps.
Therefore, number of 32-cent stamps is [tex]2x[/tex].
Now, total cost of the stamps is $ 3.36 = 336 cents
Cost of 1 20-cent stamp is 20 cents. So, cost of [tex]x[/tex] 20-cent stamps is [tex]20x[/tex]. Similarly, cost of [tex]2x[/tex] 32-cent stamps is [tex]32(2x)=64x[/tex]
Total cost = [tex]20x+64x=84x[/tex]
As per question,
[tex]84x=336\\x=\frac{336}{84}=4[/tex]
Number of 20-cent stamps = [tex]x = 4[/tex]
Number of 32-cent stamps = [tex]2x=2\times 4=8[/tex]
So, Charlie used 4 20-cent stamps and 8 32-cent stamps.
Answer:
No. of 32 cent stamps = 8
and that of 20 cent stamps = 4
Explanation:
Let no. of 32 cent stamps used be x and the number of 20 cent stamps used be y.
We are given that total postage on a package put by Charlie by using only 32 and 20 cent stamps is equal to $3.36.
So, since 100 cents make one dollar, $3.36 = 336 cents.
So,
32x + 20y = 336
Also we are given that Charlie used twice as many 32 cent stamps as 20 cent stamps which can be written as,
x = 2y
Substituting this equation in previous equation we get
32 [tex]\times[/tex]2y + 20y = 336
=> 64y + 20y = 336
=> 84y = 336
=>y = 4
Putting the value of y in x = 2y we get x = 2*4 = 8
So, no. of 32 cent stamps = 8 and that of 20 cent stamps = 4

The seventh grade class supplied bags of snacks and beverages for the school dance They supplied19 more beverages than bags of snacks The dance was supplied with a total of 371 items.
Answer:
The number of number of bags of snacks = m = 176
The number of beverages supplied = m + 19 = 176 +9 = 185
Step-by-step explanation:
Let us assume the number of bags of snacks = m
So, the number of beverages supplied = m + 19
Total number of items supplied = 371
⇒ Number of (snacks + beverages) supplied= 371
⇒ m + (m +19) = 371
or, 2 m = 371 - 19 = 352
or, m = 352 / 2 = 176
⇒ m = 176
Hence the number of number of bags of snacks = m = 176
So, the number of beverages supplied = m + 19 = 176 +9 = 185

Michael's father brought him a 16-foot board to cut into shelves for his bedroom. Michael plans to cut the board into 11 equal size lengths for his shelves.
The saw blade that Michael will use to cut the board will change the length of the board by -0.125 inches for each cut. How will this affect the total length of the board?
Answer:
The remaining wood will be 1.25 inches shorter.
Step-by-step explanation:
Only 10 cuts are required to cut the board into 11 equally sized lengths. Thus, the length of the board after these cuts have been made will be
10(0.125 inches), or 1.25 inches, shorter.
By making 10 cuts, the total length of the board will be reduced by 1.25 inches due to the saw blade reduction. After converting this to feet, Michael will have approximately 15.896 feet of board left.
Explanation:Michael has a 16-foot board that he plans on cutting into 11 equal lengths. This means he will need to make 10 cuts (as the 11th 'cut' is actually the end of the board not actually needing a cut). The saw blade will decrease the length of the board by -0.125 inches for each cut. To solve this, we multiply the number of cuts by the length that will be reduced by the saw blade. That gives us 10 x -0.125 = -1.25 inches. That means that the total usable length of the board will be reduced by 1.25 inches. We need to convert this to feet since the original length of the board is in feet. There are 12 inches in foot, so -1.25 inches is about -0.104 feet. Thus, the total length of the board after all the cuts will be 16 - 0.104, or approximately 15.896 feet.

Elliot is standing at the top of a store escalator that leads to the ground floor below. The angle of depression from the top of the escalator to the floor is 42.51 degree, and the escalator is 16 feet long. How far the top of the escalator from the ground floor? Round your answer to the nearest foot.
A. 41 feet
B. 17 feet
C. 12 feet
D. 11 feet
Answer:
The answer is 11
Step-by-step explanation:
Final answer:
The distance between the top of the escalator and the ground floor is approximately 12 feet.
Explanation:
To find the distance between the top of the escalator and the ground floor, we can use trigonometry. We have the length of the escalator (16 feet) and the angle of depression (42.51 degrees). The distance we need to find is the opposite side of the right triangle formed by the top of the escalator, the floor, and the length of the escalator. We can use the sine function to find this distance.
The formula is sin(angle) = opposite/hypotenuse. Plugging in the values, we get sin(42.51) = opposite/16. Solving for opposite, we have opposite = sin(42.51) * 16.
Using a calculator, we find that opposite ≈ 12.014 feet. Rounding to the nearest foot, the distance between the top of the escalator and the ground floor is approximately 12 feet.
