Answer:
l = (P-2w)/2
Step-by-step explanation:
P = 2l + 2w
move 2w to the left to leave the l variable by itself
P - 2w = 2l
divide by 2 on both sides to leave l by itself
(P - 2w) / 2 = l or l = (P - 2w) / 2

Declan is moving into a college dormitory and needs to rent a moving truck. For the type of truck he wants, Company A charges a 30$ rental fee plus $0.95 per mile driven, while Company B charges a 45$ rental fee plus $0.65 per mile driven. For how many miles is the cost of renting the truck the same at both companies?
Both companies will charge the same cost for renting the truck for 50 miles.
Given that
Declan is moving into a college dormitory and needs to rent a moving truck.
For the type of truck he wants, Company A charges a 30$ rental fee plus $0.95 per mile driven,
Company B charges a 45$ rental fee plus $0.65 per mile driven.
To find
How many miles is the cost of renting the truck the same at both companies?
So, according to the question
we have,
Charges of company A
For rent = $30
For drive = $0.95 per mile
Total cost charges by company A = 0.95(The total distance traveled by truck) + 30
Charges of company A
For rent = $45
For drive = $0.65 per mile
Total cost charges by company A = 0.65(The total distance traveled by truck) + 40
Let's assume The total x miles distance traveled by truck is produced same cost for both companies.
So, we can say that
Total cost charges by company A = Total cost charges by company B
Now, putting the all given values
We will get,
0.65(x) + 45 = 0.95(x) + 30
0.65x + 45 = 0.95x + 30
0.95x - 0.65x = 45 - 30
0.3x = 15
x = 15/0.3
x = 50
At 50 miles is the cost of renting the truck the same at both companies

Answer: 4√2
square root of a number is the factor that we can multiply by itself to get that number.
The square root symbol is also called as a RADICAL.
Perfect squares are the squares of the integers also called as square numbers.
to find the square root of non-perfect squared numbers we have to check the number with a near-perfect squared numbers
how to find square root of non perfect squared numbers:
If we can't figure out what factor multiplied by itself will result in the given number, we can make a factor tree.
Factor tree of 32 = 2*2*2*2*2
= (2*2) * (2*2) *2
= (4)2 *2
Therefore √/32 = √/2*2*2*2*2

An airplane is at an altitude of 1200 m, the angle of depression to a building at the airport on the ground measures 28∘. Find the distance from the plane to the building. Round your answer to the nearest tenth. Hint: Find the hypotenuse.
The distance from the plane to the building is _________ meters.
Answer:
The distance from the plane to the building is ___2553.2___meters.
Step-by-step explanation:
Given that An airplane is at an altitude of 1200 m.
The angle of depression to a building at the airport on the ground measures 28°.
We need to find the distance from the plane to the building.
Please check the attached diagram.
Let 'x' be the required distance in meters.
It forms a right-angled triangle as shown in the attached diagram.
The angle = Ф = 28°
The opposite to angle = 1200 meters
All we need to find the hypotenuse to determine the distance from the plane to the building.
Using the trigonometric ratio
sin θ = Perpendicular ÷ Hypotenuse
sin (28°) = 1200 ÷ x
x = 1200/sin (28°)
= 1200 / 0.47 ∵ sin (28°) = 0.47
= 2553.2 m
Thus, the distance from the plane to the building is ___2553.2___meters.
Mrs. Cole has to choose two pieces of fruit for her lunch. If she randomly takes two pieces of fruit from a bowl of 8 oranges and 8 apples, what is the probability she will choose two apples? (Mrs. Cole does not put back the first piece of fruit before she takes the second piece of fruit) P(apple, apple)
Answer:
2/16 I think
Step-by-step explanation:
if she only wants two apples and there is a total of 16 peices of fruit in the bowl she has a 2/16 chance she will get an apple
The probability she will choose two apples is 7/30.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Total Apple= 8
Total Oranges= 8
So, on the first pick the probability of getting Apple
= 8/16
Now, in second pick the number of apple remained = 7
So, the probability of getting apples on second pick
= 7/ 15
So, the probability she will choose two apples
= 8/16 x 7/15
= 7/30.

What is the unit rate?
Will give brainliest
Answer:
1 week 2 inches
Step-by-step explanation:
Pretty self explanatory
so we started with 4cm and by week 3 its 10cm.
So since the 4cm doesn’t count toward the 10 cm since it was already there, that turns it into 6 becuase 10-4 is 6. So 3 weeks, 6 inches, find the unit rate by dividing 6 and 3 and you’ll get 2, so 2 inches every week, now to check they gave us another week which is by 6 weeks, its 16 cm tall, now remember to subtract the 4, so 12, 12/6=2. So 2 inches every week.
DOUBLE CHECK:
So 6 weeks in total, thats 12cm becuase each week is 2cm 6*2=12. Add the 4 from the beginning, it’s 16
TRIPLE CHECK
make equation:
X for growth each week
6*x+4=16
You’ll get 2
