When a number is increased by 5.5%, the result is 60. What is the original number to the nearest tenth?
Answers
Answer: 56.9
Step-by-step explanation:
Let the original number be denoted by x.
We are informed that when the number is increased by 5.5%, the result is 60. This can be represented by:
x + (5.5% of x) = 60
x + (0.055 × x) = 60
x + 0.055x = 60
1.055x = 60
x = 60/1.055
x = 56.9
The original number is 56.9

Sandra has a rectangular pool in her backyard that is 9 feet long and 4 feet wide. A resort has a pool that is similar in shape, as shown. How long is the resort pool, in feet?
Answers
Answer:
Length of the resort pool is 13.5 ft.
Step-by-step explanation:
Since, both the rectangular pools are similar in shape,
Corresponding sides of these pools will be proportional.
By the property of similarity,
[tex]\frac{\text{Length of resort pool}}{\text{Length of backyard pool}}= \frac{\text{Width of the resort pool}}{\text{Width of the backyard pool}}[/tex]
[tex]\frac{l}{9}=\frac{6}{4}[/tex]
l = [tex]\frac{6\times 9}{4}[/tex]
l = 13.5 ft
Therefore, length of the resort pool will be 13.5 ft.

how do i figure out prime numbers
Answers
Answer:
You can figure out prime numbers by simply knowing that you can divide that number not more than one. For example, you could know that a prime number is 7 because you can only divide it once like 7 divided by 1. While for number 14, you can divide it twice which isn't a prime number because there is 14 divided by 2 and 14 divided by 1 which is more than one to divide. That's possibly an easy way to understand how to figure them out.
I've gotta find the value of the variable if m<1=2x+44 and m<5=5x+38
Answers
Answer:
Line a is parallel to line b:
m∠1=m∠ 5, because they are correspondent angles, then:
2x+44=5x+38
Solving for x:
2x+44-2x-38=5x+38-2x-38
6=3x
3x=6
Dividing both sides of the equation by 3
3x/3=6/3
x=2
2. Would be move terms 5=5x+38 then calculate -5x= 38-5 then divide both sides -5x =33 then it would be x= - 33/5

There are 16 people on the bus. Some adults and some are children. There are more adults than children. Write down different ratios of adults to children that might be on the bus.
Answers
Answer:
11 : 59 : 713 : 3Step-by-step explanation:
There are more adults than children so the ratios made have to depict this.
These ratios should add up to 16.
Three different ratios:
11 adults : 5 children
9 adults : 7 children
13 adults : 3 children
The above will all add up to 16 and show more adults than children.
The different ratios of adults to children that might be on the bus is;
14 : 2, 13 : 3, 12 : 4, 11 : 5, 10 : 6, 9 : 7
We are given;
Number of people on the bus = 16The people on the bus consist of adults and children.
We are told that;
There are more adults than children.Thus, the different possibilities for ratio between
adults and children will be 2 numbers that add up to 16 which must not be equal. Thus, we have;
14 : 2
13 : 3
12 : 4
11 : 5
10 : 6
9 : 7

Linear, y=6x-21
Step-by-step explanation:
Graph the answer to get an idea of the shape: linear.
Use y=mx+b and m=y2-y1/x2-x1 to find formula
m=y2-y1/x2-x1=3-(-9)/4-2=12/2=6
y=6x+b
9=6(5)+b
9-30=b=-21
y=6x-21
What is the equation of a line that has a y-intercept of -3 and is parallel to the line 3x = 4 + 5y?
Answers
Answer:
y = (3/5)x - 3
Step-by-step explanation:
If 3x = 4 + 5y, then
5y = 3x - 4
y = (3/5)x - 4/5
*** The given equation's slope is (3/5). For the new line to be parallel to the old one, it must have the same slope or 'slant', 3/5.
*** The requested y-intercept is -3.
For y = mx + b, 'm' is the slope and 'b' is the y-intercept.
The answer should be y = (3/5)x - 3 in 'y = mx + b' slope-intercept form.
You have $20 and earn $0.75 for each cup of orange juice you sell. Write an equation that represents the total amount A (in dollars) you have after selling j cups of orange juice.
Answers
Answer:
A= 20 + 0.75*j
Step-by-step explanation:
Giving the following information:
You have $20 and earn $0.75 for each cup of orange juice you sell.
To calculate the total amount of dollars (A), we need to use the following formula:
A= 20 + 0.75*j
j= number of cups
For example, for 15 cups:
A= 20 + 0.75*15
A= $31.25

Answers
Answer:
(half of base)² + (height)² = (20)²
Step-by-step explanation:
In an isosceles triangle, the angle bisector from the 3rd angle to the opposite side is a perpendicular bisector, so you split the isosceles triangle into two congruent right triangles.
This technique of 'splitting the isosceles' is used a LOT.

Add a grocery store bananas cost $.90 each and oranges cost $.80 each Ava has $15 to spend if Ava wants to buy an equal amount of bananas and oranges at most how many of each can't you buy
Answers
Answer:
9
Step-by-step explanation:
We are given that
Cost of each banana=$0.90
Cost of each orange=$0.80
Ava have total money=$15
We have to find the number of each if Ava wants to buy an equal amount of bananas and oranges at most.
Let x be the number of each.
According to question
[tex]0.9x+0.8x=15[/tex]
[tex]1.7x=15[/tex]
[tex]x=\frac{15}{1.7}[/tex]
[tex]x=8.8\approx 9[/tex]
[tex]x=9(approximately)[/tex]
Hence, number of banana bought=9
Number of oranges bought=9
Solve for c.
40 + 2 < 10
A
AL
s
Answers
Answer:
c < 2
Step-by-step explanation:
We have an inequality and are asked to solve for the variable "c."
4c + 2 < 10
To solve for c, we need to get it by itself, isolate it in every way possible.
4c + 2 < 10
Subtract 2 from both sides :
4c < 8
Now before we move on, take this into consideration, sometimes the inequality sign can be switched but under one condition. And that is when you divide both sides by a negative, since we are not dividing by a negative, no switch of the sign is needed.
Divide 4 from both sides to get c alone :
c < 2
