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:

20$

Step-by-step explanation:

50 - (2x - 10) = x

50 + 10 = x + 2x

60 = 3x

60/3 = x

20 = x

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

[tex]a : 4^2\\\\b: 4ft[/tex]

Step-by-step explanation:

[tex]\sqrt{16} = 4\\a : 4^2\\\\b: 4ft[/tex]

The area of the solar panel written as a power is 4 square feet.

The side lengths of the solar panel are 4 feet.

Area of square is the square of its side.

It is given that a square solar panel has an area of 16 square feet.

By simply using this formula;

[tex]\sqrt{x} = x^\frac{1}{2}[/tex]

Taking root square we get;

[tex]\sqrt{16} = 4[/tex]

Thus, power = [tex]4^{2} ft[/tex]

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 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:

B

Step-by-step explanation:

24 - 7 = 17.

If there are 365 days in a year, sometimes 366, you would multiply 17 by 365 or 366.

17 x 365 = 6205

17 x 366 = 6222.

if 3/4 years aren't leap year, then there answer would be B, 365.

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]
