The boat travels x miles per hour from one island to another island in 2.5 hours. The boat travels 5 miles per hour faster on the return trip of 2 hours. What is the distance between the island?
Answers
The distance is the same so, 2.5 multiplied by x = 2×(x+5).
It took 2.5 hrs to get there and 2 hrs to return. Now all we have to do is solve.
2.5*x = 2x + 10
.5x = 10
x=20
Therefore, the distance between islands is 2.5 × 20 = 50 miles.

An architect notices that the scale on a blueprint he is using has been torn off. However, he sees that a 12.5-ft. wall that has been built is 5 in. long on the blueprint. What is the scale for this blueprint?
Answers
Answer:
The scale is : 1 in : 2.5 ft
Step-by-step explanation:
An architect notices that the scale on a blueprint he is using has been torn off.
However, he sees that a 12.5-ft. wall that has been built is 5 in. long on the blueprint.
Let the scale be x
[tex]\frac{5}{12.5} =\frac{1}{x}[/tex]
So, scale = [tex]x=\frac{12.5}{5}[/tex] = 2.5
So, the answer is : 1 in : 2.5 ft

15:10
and further simplified to
3:2
I hope this helps!~~♡♡ Chyna
Answer: 3:2
Step-by-step explanation:
Given : An animal shelter currently only has 30 dogs and 20 Cats.
i.e. Number of dogs = 30
Number of cats = 20
Then, the ratio of cats to animals is given by :-
[tex]\dfrac{\text{Number of cats}}{\text{Number of animals}}\\\\=\dfrac{30}{20}\\\\=\dfrac{3}{2} \ \ \text{[By dividing 10 in the numerator and denominator]}[/tex]
Therefore, the ratio of cats to animals = 3:2

Two less than twice a number equals the opposite of the same number. Write an equation to represent this statement, then solve.
Answers
First, isolate the variable, to do this, add X to both sides. This creates 3X - 2 = 0, then add 2 to both sides. This makes 3X = 2, divide this by 3 and you get the answer: X = 2/3.
To check it, 2*2/3 - 2 is -2/3, which means our answer is correct.

An item that is normally sells for $130 is marked down 30%. What is the sale price
Answers
To find the sale price of an item that is normally $130 with a 30% markdown, calculate the discount amount ($39) and subtract it from the original price to get a sale price of $91.
The question asks to calculate the sale price of an item after a 30% markdown. To determine the sale price, you have to first calculate the discount amount and then subtract it from the original price of the item. Here's how you do it:
Find the discount amount: original price x discount rate.Subtract the discount amount from the original price to get the sale price.For an item that is normally sold for $130 and is marked down 30%, the sale price can be calculated as follows:
Discount amount: $130 x 0.30 = $39.Sale price: $130 - $39 = $91.What is the length of the hypotenuse of the triangle? 26 ft 34 ft 68 ft 74 ft
Answers
so
10^2 +24^2=C^2
100+576=C^2
676=C^2
so then we find the square root of 676 which is
26.
so C^2= 26
answer 26 ft
Answer: 26 ft.
Step-by-step explanation:
In the given picture, there is a right triangle.
The legs of the right triangles are 10 ft and 24 ft.
To find the length of hypotenuse, we use Pythagoras theorem, we get
[tex]H^2=10^2+24^2\\\\\Rightarrow\ H^2=100+576\\\\\Rightarrow\ H^2=676\\\\\Rightarrow\ H=\sqrt{676}\\\\\Rightarrow\ H=26\ ft[/tex]
Hence, the length of the hypotenuse = 26 ft.
Pythagoras theorem says that the square of the hypotenuseis equal to the sum of the squares of the other two sides.What is the difference ? X/x^2-2x-15-4/x^2+2x-35

The transformation of triangle abc is an example of what
Answers
Final answer:
The transformation of triangle ABC is an example of a linear transformation that preserves lines and parallelism.
Explanation:
The transformation of triangle ABC is an example of a linear transformation.
A linear transformation is a transformation that preserves lines and parallelism. It transforms lines into lines and takes parallel lines to parallel lines.
For example, if triangle ABC is transformed into triangle A'B'C', the corresponding sides of the triangles will be parallel. Additionally, any lines within the triangle will remain lines after the transformation.

divide both sides by h
[tex]b_{1}[/tex] + [tex]b_{2}[/tex] = [tex]\frac{2A}{h}[/tex]

Answers
using the givens we construct first this equation
[tex]25x + 15y = 1475 [/tex]
then this one
[tex]x + y = 75 [/tex]
multiply the second by 15 to get
[tex] 15x + 15y = 1125[/tex]
now subtract it from the first to get
[tex]10x = 350 \\ x = 35[/tex]
substitute to find that
[tex]35 + y = 75 \\ y = 40[/tex]

Daniel is a singer, and he promises his agent that he will give him a 25% commission based on what he makes from a show. After paying the agent, Daniel takes home $120. Use the diagram to answer the following questions.
Daniel’s agent made .
Daniel and the agent made a total of from the show.
Answers
Answer:
Daniels agent made $40.
Daniel and the agent made a total of $160 from the show.
Step-by-step explanation:
Given:
Let the total amount made from the show = x
Daniel's agent made = 25% of x
Daniel made = $120
From the question, we know that the total amount is the sume of what daniel and the agent took.
So,
x = 120 + 25% of x
x-0.25x = 120
0.75x = 120
x = 160.
Hence the total amount made from the show is $120.
Daniel's agent made = 25 % of 160
= 0.25*160
= 40
Hence, Daniel's agent made $40 from the show.
Answer:
40
160
