Answer:32

Step-by-step explanation:firs we multiply 5*4 =20 .then we subtract 2-1=1 add those numbers 20+1=21 and then add 11 which equals 32

s = # of songs

y = total amount of money

$11 + $1(35) = y

Simplify the right side

$11 + $35 = y

Combine like terms

$46 = y

If he downloaded 35 songs, he would have ti pay $46

If he downloaded s amount of songs, he would have to pay $11 + $1s = y

Answer:

Pine tree seedlings

Step-by-step explanation:

An experimental unit refers to the subject or factor under investigation. The subject or factor is subjected to different treatments in the course of the study. In the case of the experimental situation described above, the pine tree seedlings are the experimental units that actually received the treatments.

The treatments included being subjected to full or reduced light in the greenhouse. The response of the seedlings to these treatments would determine the outcome of the study.

Answer & Step-by-step explanation:

On the left:

There are 4 triangles that indicate -x, so this is -4

There are 3 circles that indicate -1, so these are -3.

Insert as an expression:

[tex]-4x-3[/tex]

On the right:

There are 2 triangles that indicate -x, so this is -2x.

There are 2 circles that indicate -1, so these are -2.

Insert as an expression:

[tex]-2x-2[/tex]

Combine both expressions into an equation:

[tex]-4x-3=-2x-2[/tex]

Solve for x. Add 3 to both sides:

[tex]-4x-3+3=-2x-2+3\\\\-4x=-2x+1[/tex]

Add 2x to both sides:

[tex]-4x+2x=-2x+2x+1\\\\-2x=1[/tex]

Isolate the variable. Divide both sides by -2:

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

:Done

Answer:

C

Step-by-step explanation:

Did the test and got it right.

The function g(x) = 2x + 3 if  f(x) = 2(x + 1)² and f(g(x)) = 2(2x + 4)² option (C) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Suppose f(x) = 2(x + 1)² and f(g(x)) = 2(2x + 4)². What is g(x)?

A.g(x) = x + 3

B.g(x) = x + 4

C.g(x) = 2x + 3

D.g(x) = 2x + 4

We have:

f(x) = 2(x + 1)²

Let take g(x) = 2x + 3

Find f(g(x))

f(2x + 3) = 2[(2x+3) + 1]²

= 2(2x + 4)² = f(g(x))

Thus, the function g(x) = 2x + 3 if  f(x) = 2(x + 1)² and f(g(x)) = 2(2x + 4)² option (C) is correct.

Answer:

-2

Step-by-step explanation:

When you add a negative number, instead of going 5 places ahead, it goes 5 places back on a number line.

So you would treat this like a subtraction problem. Instead of 3+(-5) it would act like 3-5.

Answer:

The unit rate in miles per hour is 2.5 mph.

Step-by-step explanation:

Since Matthew rode his bicycle for 5/8 of a mile in a quarter of an hour, to determine the speed at which he was traveling we must perform the following calculation:

1/4 x 4 = 1 hour

5/8 x 4 = miles that would have been covered in one hour

20/8 of a mile would have been covered in one hour

20/8 = 2.5

2.5 miles would have been covered in an hour, with which his speed was 2.5 mph.

But where are the rectangles??

Answer: 8 bags.

Step-by-step explanation:

It is given that, a make-your-own ice pop kit says to pour 4 fluid ounces of juice into each bag.

We need to find the number of ice pop bags we can fill with 1 quart of juice.

We know that,

1 quart = 32 ounces

We have  32 ounces of juice and each bag contains 4 fluid ounces.

[tex]\text{Number of ice pop bags}=\dfrac{\text{Total juice}}{\text{Juice contained in each bag}}[/tex]

[tex]\text{Number of ice pop bags}=\dfrac{32}{4}[/tex]

[tex]\text{Number of ice pop bags}=8[/tex]

Therefore, 8 ice pop bags we can  fill with 1 quart of juice.

Answer:

8 bags

Answer:

Purchases= $39,800

Step-by-step explanation:

Giving the following information:

Beginning Supplies= 1,400

Ending Supply balance= 4,500

COGS= 36,700

To calculate the purchases, we need to use the following formula:

Purchases= COGS + desired ending inventory - beginning inventory

Purchases= 36,700 + 4,500 - 1,400

Purchases= $39,800

Answer:

Every triangle has three medians, just like it has three altitudes, angle bisectors, and perpendicular bisectors. The medians of a triangle are the segments drawn from the vertices to the midpoints of the opposite sides. The point of intersection of all three medians is called the centroid of the triangle.

Answer:

B. 40°

Step-by-step explanation:

m<PTQ = (x + 28)°

m<RTS = (2x + 16)°

Angle PTQ and angle RTS are vertically opposite angles, therefore, m<PTQ = m<RTS

[tex] x + 28 = 2x + 16 [/tex]

Solve to find the value of x

[tex] x + 28 - 2x = 2x + 16 - 2x [/tex] (subtracting 2x from each side)

[tex] -x + 28 = 16 [/tex]

[tex] -x + 28 - 28 = 16 - 28 [/tex] (subtracting 28 from each side)

[tex] -x = -12 [/tex]

[tex] x = 12 [/tex] (dividing each side by -1)

Find angle PTQ:

m<PTQ = (x + 28)°

Plug in the value of x

m<PTQ = 12 + 28 = 40°

Answer:

Step-by-step explanation:

Given

Initial Temperature = -10

Increment = 5

Required

Solving (a): Write an Equation

The equation is to add the initial temperature and the increment

i.e

Equation = Initial Temperature + Increment

Solving (b): Solve the equation

Substitute values for initial temperature and the increment

Result = -10 + 5

Result = -5

Solving (c):

It's a negative answer because the increment in temperature is not greater than the initial temperature
