PLEASE HELP !! DUE SOON :(

Answer:

The answer is letter A.

Step-by-step explanation:

 The amount that each company charges per hour on the pool is known, however the amount of hours they will be working is not, and is needed to distinguish which company is cheaper. Therefore, the number of hours is  substitued by x and it is right next to the amount they charge for each hour. To find what each company charges, you must sum up what they charge and what they charge per hour, times the hours they will have to work on it( which is unknown and by x).

Step-by-step explanation:

simple interest = principal×rate×time

S.I = $50×(14÷100)×3

S.I=$50×0.14×3

S.I=$21

Amount= principal + simple interest

Amount = $50+$21

Amount = $71

Answer:

A

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

1. P(E)>P(D) (Event E is more likely to occur, therefore it has a greater probability)

2. P(E)>0.5 (The probability of event D is given as 0.5, so rewrite P(D) in the inequality)

3. 0.5 is equal to 0.5 and 0.1 is less than 0.5, so you can rule out options A and D

4. This leaves us with options 1.5 and 0.9, but it is impossible to have a probability that is greater than equal to one, so you can immediately rule out B

5. After this elimination process, the only remaining answer is C) P(E)=0.9

There are 14 blue beads in total. If you use 14 blue needs and 6 green needs that is 14+ 6 which equals 20.

9k³ = 1125

k³ = 1125 : 9

k³ = 125

k = 5 (because 5³ = 5 * 5 * 5 = 125)

Answer:

100 miles.

Step-by-step explanation:

When we look at the graph, we can see that they want to see how far the ship will travel in 4 hours.  So lets look at the graph and at 4 hours, we can see the ship will travel 100 miles.

Answer:

Use a ratio.

20/60 = x/180

180/60 = 3, so 20*3 is 60.

The answer is 60.

Answer:

60

Step-by-step explanation:

Find out how many phone calls Mr. Grinnell receives in 1 minute.

60 mins = 20

1 min = 20 ÷ 60 = 0.333

180 mins = 0.333 x 180 = 59.94

59.94 rounded to the nearest whole number = 60

Answer:

the coefficient is 2

2x^4 = 2 * x^4 = 2 is the coefficient

hope that helps

Answer:

2

Step-by-step explanation:

The coefficient of a term is the number that multiplies the variables of the term.

In the term 2x^4, the number multiplying the variables is 2, so the coefficient is 2.

Answer: [tex]20\times 20, 16\times 25, 10\times 40[/tex]

Step-by-step explanation:

Given

The volume of the pool is [tex]1600\ ft^3[/tex]

Depth of water is [tex]d=4\ ft[/tex]

Suppose A is the base of the pool

[tex]\Rightarrow V=A\times d\\\Rightarrow 1600=A\times 4\\\Rightarrow A=400\ ft^2[/tex]

This area can be written as

[tex]\Rightarrow A=10\ ft\times 40\ ft\ or\\\Rightarrow A=16\ ft\times 25\ ft\ or\\\Rightarrow A=20\ ft\times 20\ ft[/tex]

Answer:

Is there a proportional relationship between the number of scoops and the number of​ dogs?

No.

Step-by-step explanation:

A proportional relationship is something like:

y = k*x

Here y can represent the number of scoops of dog food, and x the number of dogs.

First, we know that for 4 dogs he prepares 8 scoops of dog food, then:

8 = k*4

If the relationship is proportional, then we should have a similar equation for the case of 6 dogs, where he prepares 15 scoops of dog food:

15 = k*6

So if we have the same k in both equations, then there is a proportional relationship between the number of scoops and the number of dogs.

In the first equation we have:

8 = k*4

8/4 = k

2 = k

And in the second equation we have:

15 = k*6

15/6 = k

2.5 = k

The values of k are different, so no, there isn't a proportional relationship between the number of scoops and the number of dogs.

Remark

The solution to this is to add the two vertically opposite arcs and take 1/2 of the result to get the intersecting angle of the chords.

Solution

<x = 1/2 (arc measure of 116 + 74)

<x = 1/2 (190)

<x = 95

Answer:

60 feet

Step-by-step explanation:

Perimeter is the sum of the four sides of a rectangle

the formula for the perimeter of a rectangle = 2 x (length + breadth)

2 x (10 + 20)

2 x (30)

= 60 feet

Alternatively, you can add the sides together : 10 + 10 + 20 + 20 = 60 feet

Answer:

No.

Step-by-step explanation:

In order for this equation to be true, either the 8 would have to be negative or the 11.
