Help please, and help me answer the other ones Ive posted if you can, don’t comments just for points please, I really need help and a explanation m.
Answer:
Step-by-step explanation:
the Pythagorean Theorem.
A^2 + B^2 = C^2
In this case, A = 13 and B = 5. C = length of ladder.
13^2 + 5 ^2 = c^2
169 + 25 = 194
194 = c^2
square root both sides and you get:
c = 13.9

The ratio of cats to dogs was 3 to 7. If there were 300 cats and dogs in all, how many were cats?
Answer:
700
Step-by-step explanation:
The ratio of cats to dogs was 3:7
Divide 300 by 3
=100
multiply 100 and 7
=700
Step-by-step explanation:
let common ratio be x
3x + 7x = 300
10 x = 300
x = 300/10= 30
there common ratio x is 30
3 x 30 =90 cats
7 x 30 = 210 dogs
Martha sells custom painted square canvases. She determined that the amount of tissue paper she'll need to wrap each canvas can be represented by
y= x^2 + 2x + 1, where y is the total square inches of tissue paper and x is the side length of the canvas in inches. Write and solve an equation to determine the side length of the canvas is Martha needs 49 square inches of tissue paper.
Given:
The equation is
[tex]y=x^2+2x+1[/tex]
where y is the total square inches of tissue paper and x is the side length of the canvas in inches.
To find:
The side length of the canvas is Martha needs 49 square inches of tissue paper.
Solution:
We have,
[tex]y=x^2+2x+1[/tex]
Putting y=49, we get
[tex]49=x^2+2x+1[/tex]
[tex]0=x^2+2x+1-49[/tex]
[tex]0=x^2+2x-48[/tex]
Splitting the middle term, we get
[tex]0=x^2+8x-6x-48[/tex]
[tex]0=x(x+8)-6(x+8)[/tex]
[tex]0=(x+8)(x-6)[/tex]
Using zero product property, we get
[tex]x+8=0[/tex] and [tex]x-6=0[/tex]
[tex]x=-8[/tex] and [tex]x=6[/tex]
Side length cannot be negative. So, only possible value of x is 6.
Therefore, Martha needs 6 inches side length of the canvas for 49 square inches of tissue paper.

To purchase $14,500 worth of restaurant equipment for his business, Hans made a down payment of $1800 and took out a business loan for the rest. After years of paying monthly payments of $562.88. , he finally paid off the loan.
Answer:
hello your question is incomplete below is the complete question
To purchase $14,500 worth of restaurant equipment for his business, Hans made a down payment of $1800 and took out a business loan for the rest. After 2 years of paying monthly payments of $562.88. , he finally paid off the loan. What was the total amount Dean ended up paying for the equipment ( including the down payment and monthly payments )
answer: $15309.12
Step-by-step explanation:
Initial cost of equipment = $14500
Down payment = $1800
cost of equipment = 14500 - 1800 = $12700
Monthly payment = $562.88
Therefore payment made after 2 years = ( 562.88 * 24 ) = $13509.12
Total amount paid by Dean for the equipment
= down payment + monthly payments
= $1800 + $13509.12
= $15309.12

Answer:
y<13/2
Step-by-step explanation:
5y+4<3y+17
5y-3y<17-4
2y<13
y<13/2
Answer:
y < [tex]\frac{13}{2}[/tex]
Step-by-step explanation:
Given
5y + 4 < 3y + 17 ( subtract 3y from both sides )
2y + 4 < 17 ( subtract 4 from both sides )
2y < 13 ( divide both sides by 2 )
y < [tex]\frac{13}{2}[/tex]

#7: Five containers, each weighing the same amount, were placed on a 30-pound
platform. The platform and containers were lifted onto a train car. The maximum weight
that can be lifted by the cable is 780 pounds. Which inequality represents the possible
weight of one container, x, on the platform?
A. x < 130
B. x < 150
C. x < 156
D. x < 162
Answer:
Option (B)
Step-by-step explanation:
Let the weight of one container = x pounds
Therefore, weight of 5 containers = 5x pounds
Weight of the platform = 30 pounds
Total weight of the platform and containers = (5x + 30) pounds
If the maximum weight that can be lifted by the cable = 780 pounds
Inequality representing this situation will be,
(5x + 30) < 780
5x < 780 - 30
5x < 750
x < 150
Therefore, Option (B) is the answer.

A group of friends goes out to dinner. The total bill, without tax, is $63. If tax on the meal is 6% and if an 18% tip is left on the $63 total billwhat is the total amount paid?
Answer: $78.12
Step-by-step explanation:
First find the tip to be paid on the pretax amount:
= 63 * 18%
= $11.34
Then find the tax to be paid:
= 63 * 6%
= $3.78
Add the tip and the tax to the pretax bill:
= 63 + 11.34 + 3.78
= $78.12

Kim finished a race in 48.47 seconds. This is 9.7 seconds faster than her practice time. What was Kim's practice time? A 38.77 seconds B 47.50 seconds C 49.44 seconds D 58.17 seconds
Answer:
58.17 seconds
Step-by-step explanation:
48.47 + 9.7 = 58.17
Answer:
38.77 seconds
Step-by-step explanation:
Given that,
Kim finished a race in 48.47 seconds.
This is 9.7 seconds faster than her practice time.
We need to find Kim's practice time.
Finished time = 9.7 + (practice time)
i.e.
Practice time = (Finished time-9.7)
= 48.47 - 9.7
= 38.77 seconds
Hence, the practice time is 38.77 seconds.
In an office, there are 75 women and 125 men .Find the ratio of
the number of men to the number of women.
Given:
In an office, there are 75 women and 125 men.
To find:
The ratio of the number of men to the number of women.
Solution:
We have,
Number of men = 125
Number of women = 75
The ratio of the number of men to the number of women is:
[tex]\text{Required Ratio}=\dfrac{\text{Number of men}}{\text{Number of women}}[/tex]
[tex]\text{Required Ratio}=\dfrac{125}{75}[/tex]
[tex]\text{Required Ratio}=\dfrac{5}{3}[/tex]
[tex]\text{Required Ratio}=5:3[/tex]
Therefore, the ratio of the number of men to the number of women is 5:3.
