A store sells bottles of water for $1.50 each. During the first hour the store was open, x bottles of water were sold. During the
second hour, the store sold 3 fewer bottles of water than it sold during the first hour. During the third hour, it sold three times as
many bottles of water as it sold during the second hour. The store was paid a total of $117.00 for bottles of water sold during these
three hours. The equation shown below represents these sales.
1.5x + 1.5(x - 3) + 1.5.3(x - 3) = 117
How much money was the store paid for bottles of water sold during the second hour it was open?
(A) $15.00
(B) $22.50
(C) $27.00
(D) $67.50

b=6

Answer:

[tex]b = 6[/tex]

Step-by-step explanation:

1.) We need to manipulate the equation to get b by itself.

2.) ​ Subtract 5b from each side. Combine like terms. Add 15 to each side. Combine like terms. Divide each side by 2. Simplify.

Answer and Step-by-step explanation:

The computation is shown below;

As we know that

The simple interest is

Simple interest = Principal × rate × time

For Account A, the principal would be

2 = Principal × 3.2% × 3

So, the principal is $20.83

For account B, the principal would be

38.50 = Principal × 2.2% × 30

So, the principal is $58.33

Now the interest for both the accounts are as follows

For account 1

= $20.83 × 3.2%

= $0.67

And, for the account 2

= $58.33 × 2.2%

= $1.28

As it can be seen that the account 2 has the highest interest

The same is to be considered

Answer:

[tex]g(x) = -0.1x^2 + 0.5x + 3.6[/tex]

Step-by-step explanation:

Given

[tex]h(x) = -0.1x^2 + 0.7x + 3[/tex]

Required

Determine the new function

From the question, we understand that the new function wants the water to hit the ground 1 ft farther.

1 ft farther implies x + 1

So, in the given function, we substitute x + 1 for x in [tex]h(x) = -0.1x^2 + 0.7x + 3[/tex]

This gives:

[tex]h(x + 1) = -0.1(x + 1)^2 + 0.7(x + 1) + 3[/tex]

Expand Bracket

[tex]h(x + 1) = -0.1(x + 1)(x + 1) + 0.7(x + 1) + 3[/tex]

[tex]h(x + 1) = -0.1(x^2+2x+1) + 0.7(x + 1) + 3[/tex]

[tex]h(x + 1) = -0.1x^2-0.2x-0.1 + 0.7x + 0.7 + 3[/tex]

Collect Like Terms

[tex]h(x + 1) = -0.1x^2-0.2x + 0.7x + 0.7 + 3-0.1[/tex]

[tex]h(x + 1) = -0.1x^2 + 0.5x + 3.6[/tex]

Hence, the new function is:

[tex]g(x) = h(x + 1) = -0.1x^2 + 0.5x + 3.6[/tex]

[tex]g(x) = -0.1x^2 + 0.5x + 3.6[/tex]

The new model for path of water will be, [tex]h(x+1)=-0.1x^{2} +0.5x+3.6[/tex]

To understand more, check below explanation.

The height h (in feet) of water spraying from the garden house can be modeled by,

                 [tex]h(x)=-0.1x^{2} +0.7x+3[/tex]

where x is the horizontal distance (in feet) from where you are standing.

Since, you raise the hose so that the water hits the ground 1 foot farther from where you are standing.

So that, new function will be,

              [tex]h(x+1)=-0.1(x+1)^{2} +0.7(x+1)+3\\\\h(x+1)=-0.1(x^{2} +2x+1)+0.7x+0.7+3\\\\h(x+1)=-0.1x^{2} -0.2x-0.1+0.7x+0.7+3\\\\h(x+1)=-0.1x^{2} +0.5x+3.6[/tex]

Step-by-step explanation:

Answer: a = -8

3(2x - a) = 2(3x + 12)

⇔ 6x - 3a = 6x + 24

⇔ - 3a = 24

⇔ a = -8

Step-by-step explanation:

Answer:

X=24

Step-by-step explanation:

3(2x-a)=2(3x+12)

6x-3a=6x+24

-6x both sides.

-3a=x+24

Get rid of the -3a.

x+24

divide by x both sides.

x=24

Answer:

Tammy

Step-by-step explanation:

Tammy read 7.75 hours last month. Kelley read 7.69 hours

Jim read 7.075 hours.

We would arrange the hours of reading from smallest to the highest

7.075, 7.69, 7.75

The person who spent the most time reading is the person with the highest number of hours that was spent reading. This person is Tammy.

Therefore, person who spent the most time reading is Tammy because she read for 7.75 hours.

The person who spent the most time reading is Tammy.

Therefore, from the decimals given, we can see that the highest is 7.75 hours that was used by Tammy.

Answer:

Step-by-step explanation:

Given

Engineering=120+22x;

Business=105-4x;

Biology=98+6x;

If Engineering has twice as many student as biology then,;

120+22x = 2(98+6x)

Expand

120+22x = 196+12x

Collect like terms

120-196 = 12x-22x

-76 = -10x

x = -76/-10

x = 7.6

Hence it will take like 7 and a half years before engineering has twice as many student as biology

Answer:

Cost of large popcorn = 4

Cost of small drinks = 3

Step-by-step explanation:

Given that :

Let cost of large popcorn = x

Cost of small drinks = y

Cost of 2 large popcorn and 4 small drinks

2x + 4y = 20

2x + 2y = 14

x + 2y = 10 - - - (1)

x + y = 7 - - - (2)

Subtract :

2y - y = 10 - 7

y = 3

Substitute y = 3 into (2)

x + 3 = 7

x = 7 - 3

x = 4

Hence,

Cost of large popcorn = 4

Cost of small drinks = 3

Answer:

1,362.50 Dollars

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.5%/100 = 0.045 per year.

Solving our equation:

A = 1250(1 + (0.045 × 2)) = 1362.5

A = $1,362.50

Then You Get 1362.50 Dollars
