how to find an expression for the perimeter of the rectangle
Answer:
Step-by-step explanation:
To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.
Ruben and his friends are celebrating Ruben's birthday at Adventure Zone, which has trampolines, mini golf, laser tag, and an arcade. Ruben's mom gives 18 arcade tokens to each kid at the party. In all, she gives out 144 tokens.
Use an equation to find the number of kids at Ruben's party.
The number of kids that are at Ruben's party will be 8 kids.
Let the number of kids at the party be represented by x.Number of arcades token given to each person = 18Total number of arcade tokens given out = 144Based on the information given, the equation to solve the question will be:
18 × x = 144
18x = 144
x = 144/18
x = 8
Therefore, there are 8 kids at the party.

Step-by-step explanation:
Basically, let's represent the amount of money earned in
July with x
and
August with x+90
x+(x+90)=350
2x+90=350
2x=350-90
2x=260
x=260÷2
x=130
So, Wanda earned $130 babysitting in July and in July, 130+90=$220.

Answer:
You will pay $3.78 in tax. And you would pay a total of $66.78
Step-by-step explanation:
Answer: $3.78 or $66.78 if you are looking for the total amount including tax.
Step-by-step explanation:
6% can be represented by 0.06 so multiply that by 63
63*0.06=3.78
You will pay $3.78 in taxes
The total is 66.78 but I think you are asking for the tax.
To approximate the length of a lake, a surveyor starts at one end of the lake and walks 245 yards. He then turns 110 and walks 270 yards until he arrives at the other end of the lake. Approximately how long is the lake?
Answer:
Surveying To approximate the length of a marsh, a surveyor walks 250 meters from point to point , then turns and walks 220 meters to point (see figure). Approximate the length of the marsh.
hope it helped
Step-by-step explanation:
The approximate length of the lake is 625 yards.
Given that, a surveyor starts at one end of the lake and walks 245 yards.
What is total?A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.
He then turns 110 and walks 270 yards until he arrives at the other end of the lake.
Total length of the lake is
245+110+270 =625 yards
Therefore, the approximate length of the lake is 625 yards.

Use the example as a model. Simplify the expressions.
t^37 = ✔ i
t^82 = ✔ –1
Answer:
After , the sequence repeats itself
Divide 37/4 = 9 R 1. Now use the remainder and find which one of the values of i it matches.
so
Step-by-step explanation:
The expressions are simplified as;
i. t = ∛i
ii. t = 1
How to simply the expressionsFrom the information given, we have that;
Simplifying [tex]t^3^7[/tex] = √i
When [tex]t^3^7[/tex]equals i (the imaginary unit), we can solve for "t" by taking the 37th root of both sides:
[tex]t^3^7 = i[/tex]
[tex]t = \sqrt[3]{i^3^7}[/tex]
[tex]t = i^(^3^7^/^3^)[/tex]
Since i^4 = 1 (i raised to the power of 4 is 1), we can simplify the exponent:
[tex]t = i^(^1^2 ^+ ^1^/^3^)[/tex]
[tex]t = i^1^2 ^* i^(^1^/^3^)[/tex]
Now, since[tex]i^1^2[/tex] = 1 and [tex]i^(^1^/^3^)[/tex] represents the cube root of i, we have:
t = 1 * ∛i
t = ∛i
Simplifying [tex]t^8^2[/tex] = √ –1:
Take the 82nd root of -1
[tex]t^8^2 = -1[/tex]
t = [tex]\sqrt{(-1)^8^2}[/tex]
t = √1
t = 1

. There are 2 boys for every 3 girls in Mrs. Sorrentino's class. If there are 30 students in
the class, what percentage are boys?
(Please show how to solve this question , step by step!)
Answer:
40% are boys
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 = 5 parts
Divide number in class by 5 to find value of one part of ratio
30 ÷ 5 = 6 ← value of 1 part of the ratio, then
2 parts = 2 × 6 = 12 ← number of boys in class
percentage = [tex]\frac{boys}{total}[/tex] × 100%
= [tex]\frac{12}{30}[/tex] × 100%
= 0.4 × 100% = 40%
Answer:
40% simplify the fraction then divide (boys/total) then multiply by 100
Step-by-step explanation: 2+3 = 5 is the distributer then : 30/5 = 6 then if 2 are boys 2 x 6 = 12 is the amount of boys 12/30 = 2/5 simplified and then x 100 to fraction's to find percentage 2/5 x 100 = 40%
Gold and silver are mixed in the ratio 7:4.if 36gm of silver is used.How many gold is used
Answer:
63gm
Step-by-step explanation:
7 gold : 4 silver
It gives you 36 silver.
to get from 4 silver to 36 silver you multiply by 9.
you multiply the gold by the same amount 9.
7*9= 63
you can see that for every 7 gold pieces there is 4 silver pieces. they keep piling up the pieces until there's 36 silver pieces. now they wanna know how much gold there is.
