If the perimeter in the rectangle.is 18 inches, find the length of the sideshow
Answer:
5 inches and 4 inches
Step-by-step explanation:
The perimeter is equal to 2(2x + 1) + 2(x + 2) since there are two sides of the rectangle equal to the expressions given.
Since we also know that the perimeter is 18 inches, we can set that equal to 18.
2(2x + 1) + 2(x + 2) = 18
4x + 2 + 2x + 4 = 18
6x + 6 = 18
6x = 12
x = 2
After plugging 2 back into 2x + 1 and x + 2, you get 5 and 4. Hope this helped!

A bag contains five Snickers bars, nine Milky Way bars, two Crunch bars,
and twelve Twix bars. If Jack randomly selects a candy bar, eats it, then
randomly selects another, find the probability that both candy bars were
Milky Way.
Answer:
about a 9.5 percent chance of both being a milky way
Step-by-step explanation:
Probability that both candy bars were milky way is [tex]\frac{2}{21}[/tex]
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur
Given,
Number of snickers bars = 5
Number of Milky way bars =9
Number of crunch bars = 2
Number of Twix bars = 12
Total number of Candy bars = 5+9+2+12 =28
If Jack randomly selects a candy bar, eats it, then randomly selects another
Probability = Number of favorable outcome / Number of total outcome
Probability of taking Milky way bar in first pick = [tex]\frac{9}{28}[/tex]
So Total number of candy bars and number of Milky way bar are decreased by 1.
Probability of taking Milky way bar in second pick = [tex]\frac{8}{27}[/tex]
Probability that both candy bars were milky way = [tex](\frac{9}{28}).(\frac{8}{27})=\frac{2}{21}[/tex]
Hence, Probability that both candy bars were milky way is [tex]\frac{2}{21}[/tex]

The answer to A is Gabe, the answer to B is Mila and I don't have an answer to C, try inputting it into a calculator. Sorry.
A)
y = ax + b
b = 40 as the line starts at (0 ; 40)
then the line goes down => so a < 0
between the 1st point and the second, we go 2 units on the right and we go 1 unit down
so a = - 1/2 = - 0,5
finally y = - 0,5x + 40
B)
y = ax + b
with
a = (-6 ; 0) / (0 ; -30) = 6/30 = 1/5
with the point ( 0 ; -6) we know that b = -6
finally y = 1/5x - 6
C)
we use the point (0 ; - 10)
so Amir is right as b will be - 10

Problem 8-21 (Algorithmic)
Round Tree Manor is a hotel that provides two types of rooms with three rental classes: Super Saver, Deluxe, and Business. The profit per night for each type of room and rental class is as follows:
Rental Class
Room Super Saver Deluxe Business
Type I $38 $43 —
Type II $16 $28 $45
Type I rooms do not have wireless Internet access and are not available for the Business rental class.
Round Tree's management makes a forecast of the demand by rental class for each night in the future. A linear programming model developed to maximize profit is used to determine how many reservations to accept for each rental class. The demand forecast for a particular night is 140 rentals in the Super Saver class, 50 rentals in the Deluxe class, and 40 rentals in the Business class. Round Tree has 110 Type I rooms and 110 Type II rooms.
Use linear programming to determine how many reservations to accept in each rental class and how the reservations should be allocated to room types.

Joy decided to ride her bike to visit her friend, Three miles from home her bike got a flat tire and she had to walk the remaining two miles to Justin's home. She could not repair the tire and had to walk all the way home. How many miles did Joy walk than she rode? They got the answer 4 but I am not sure how?
Answer:
4
Step-by-step explanation:
okay, so she rode 3 miles. Keep that aside
Then she had 2 walk the remaining 2 miles
She had to walk all the way home. So say for example instead of riding she walked 3 miles, then she walked that additional 2 miles. So, 5 miles. Then add the two miles she had to walk to his house. so, she walked 7 miles and rode 3 miles. 7-3= 4 miles. I attached a picture that should hopefully explain it better.

Solve for r in terms of q, s, and t
T=r-q+s
R=
Answer:
r = t + q - s
Step-by-step explanation:
t = r - q + s
goal is to isolate the variable
add q to both sides (this cancels the q out on the right side)
t + q = r - q + q + s
t + q = r + s
subtract s from both sides
t + q - s = r + s - s
t + q - s = r
In other words:
r = t + q - s

What is 70 percent of 20?
Answer:
14
Step-by-step explanation:
All you need to do is turn 70% into a decimal which is .70
Then multiply .70 and 20
.70*20
which gives you 14
The number is 14, which represents 70 percent of 20 is 14.
As we know that a percentage is normally calculated by dividing the component by the total and then multiplying by 100.
To find 70 percent of a number, we multiply the number by 70/100 or 0.7.
As per the question, we want to find 70 percent of 20.
So, we have:
70% × 20 = (70/100) × 20
To simplify the calculation, we can convert the percentage to a decimal by dividing 70 by 100, which gives us 0.7:
(70/100) × 20 = 0.7 × 20
Multiplying 0.7 by 20, we get:
0.7 × 20 = 14
Therefore, 70 percent of 20 is 14.
