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

Find the common difference in the outputs to help find the missing outputs in the table


ɑ 5 6 7 8 9
b 3.8 4.6 5.6 ? ?

Answers

we have been given table containing 6 points.

let the numbers at question mark (?) are x and y respectivelly so we can rewrite the table as:

[tex]\left[\begin{array}{cccccc}a&5&6&7&8&9\\b&3.8&4.6&5.4&x&y\end{array}\right][/tex]

In the first row we see that numbers increase by 1 so that clearly means a=4.

Now we need to find the common difference in the outputs to help find the missing outputs in the table.

4.6-3.8=0.8

5.4-4.6=0.8

we are getting common difference of 0.8 so that means missing values can be found by adding or subtracting 0.8 as per their position.

b=3.8-0.8=3

x=5.4+0.8=6.2

y=6.2+0.8=7

Hence the final answer is given by table:

[tex]\left[\begin{array}{cccccc}4&5&6&7&8&9\\3&3.8&4.6&5.4&6.2&7\end{array}\right][/tex]

An animal shelter currently only has 30 dogs and 20 Cats. What is the ratio cats to animals?

Answers

hello!

30:20
this could be simplified to
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

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.

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 speed to the island is x. The speed to return is x+5.

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.

What is the length of the hypotenuse of the triangle? 26 ft 34 ft 68 ft 74 ft

Answers

the hypotenuse is found by A^2 +B^2=C^2
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.

An item that is normally sells for $130 is marked down 30%. What is the sale price

Answers

The answer is $100 sales price because all you do is subtract the discount from the price of the original item

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.
