3. The superhero is afraid of heights.

"The superhero is afraid of heights." is independent clause because the sentence contains a subject and verb and it's a complete sentence.  

Step-by-step explanation:

An independent clause is a group of words that contains a subject and verb and expresses a complete thought. An independent clause is a sentence.

          Jim studied in the Sweet Shop for his chemistry quiz.

A dependent clause is a group of words that contains a subject and verb but does not express a complete thought. A dependent clause cannot be a sentence. Often a dependent clause is marked by a dependent marker word.  A dependent marker word is a word added to the beginning of an independent clause that makes it into a dependent clause. Some common dependent markers are: after, although, as, as if, because, before, even if, even though, if, in order to, since, though, unless, until, whatever, when, whenever, whether, and while.

         (What happened when he studied? The thought is incomplete.)

Answer: choice 3. The superhero is afraid of heights

The other choices are sentences that are incomplete because they need more structue to them. For example, sentence 1 implies that something else is going on during Marvin's guitar time. The other sentences have cliffhangers as well and they arent fully independent or on their own. Sentence 3 expesses a single complete thought without introducing some other related or tangential thought needed to complete that idea.

Answer:

The number of large boxes is 55 and the number of small boxes is 70

Step-by-step explanation:

The complete question is

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 50 pounds each, and the small boxes weigh 20 pounds each. There are 125 boxes in all. If the truck is carrying a total of 4150 pounds in boxes, how many of each type of box is it carrying?

Let

x ------> the number of large boxes

y -----> the number of small boxes

we know that

[tex]x+y=125[/tex] -----> equation A

[tex]50x+20y=4,150[/tex] ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (55,70)

therefore

The number of large boxes is 55 and the number of small boxes is 70

Answer:

The runner's unit rate is 0.09 miles/minute.

Step-by-step explanation:

Given:

Distance cover by runner = 8 miles and the time taken = 92 minutes.

Now, to calculate the runner's unit rate.

We put the formula to get the unit rate:

Velocity = distance/time

[tex]v=\frac{d}{t}[/tex]

[tex]v=\frac{8}{92}[/tex]

[tex]v=0.0869[/tex]

v = 0.09 miles/minute (approximately)

Therefore, the runner's unit rate is 0.09 miles/minute.

Final answer:

To find the runner's unit rate, divide the total miles (8) by the total minutes (92), resulting in a rate of 0.08695652 miles per minute or 5.217 miles per hour when converted.

Explanation:

The question is asking to find the unit rate of a runner who runs 8 miles in 92 minutes. To find the unit rate, we need to calculate how many miles the runner can run in one minute. This involves dividing the total miles run by the total minutes taken.

Calculation:
Unit Rate = Total Miles / Total Minutes = 8 miles / 92 minutes = 0.08695652 miles per minute.

For practical purposes and better understanding, it might be useful to convert this unit rate into miles per hour. Since there are 60 minutes in an hour, we simply multiply the unit rate per minute by 60.

Miles per hour = 0.08695652 miles/minute * 60 minutes/hour = 5.217 miles per hour.

Therefore, the runner's unit rate is 0.08695652 miles per minute, or equivalently, 5.217 miles per hour.

They must sell 18 small pizzas, 12 medium pizzas and 6 small pizzas.

Step-by-step explanation:

Let,

Small pizza = x

Medium Pizza = y

Large Pizza = z

Cost of one small pizza = $10

Cost of one medium pizza = $15

Cost of one large pizza = $40

According to given statement;

They usually sells as many small pizzas as medium and large pizzas combined.

x = y+z  

The number of medium pizzas sold is usually twice as many as large ones.

y = 2z

How many of each pizza must they sell to get $600.

10x+15y+40z = 600

The following system of equations represents the given statement;

x = y+z    Eqn 1

y = 2z      Eqn 2

10x+15y+40z = 600    Eqn 3

Putting value of x and y from Eqn 1 and 2 in Eqn 3;

[tex]10(y+z)+15(2z)+40z=600\\[/tex]

We know that y=2z from Eqn 2,

[tex]10(2z+z)+30z+40z=600\\20z+10z+70z=600\\100z=600[/tex]

Dividing both sides by 100;

[tex]\frac{100z}{100}=\frac{600}{100}\\z=6[/tex]

Putting z=6 in Eqn 2;

[tex]y=2(6)\\y=12[/tex]

Putting value of y and z in Eqn 1;

[tex]x=12+6\\x=18[/tex]

They must sell 18 small pizzas, 12 medium pizzas and 6 small pizzas.

The two consecutive even integers whose product is 440 are 20 and 22. When considered as positive and negative, they are +20 and -20, +22 and -22, respectively.

To find the two consecutive even integers whose product is 440, we need to employ some algebraic reasoning. Let's denote the first of the two consecutive even integers as x.

Given that even integers follow a pattern of +2, we can denote the next consecutive even integer as x + 2.

Hence, we're solving for the equation x * (x + 2) = 440. Solving this equation will give us our consecutive even integers, which are 20 and 22. In terms of positive and negative integers, they would be represented as +20 and -20, +22 and -22, respectively.

6 times (1/3x + 1/2) = 2x+3

The left side of the original equation becomes 2x+3. The right side is also 2x+3. Both sides are the same, so we get infinitely many solutions.

We have,

Answer: x = 3

Step-by-step explanation: To solve for x in the equation you see here, our goal is to get x by itself.

Our first step will be to isolate the term containing x which in this case is 2x. To isolate 2x, we have to get rid of the 3 by subtracting 3 from both sides of the equation.

On the left, the 3's cancel each other out and we are left with 2x. On the right, 9 - 3 simplifies to 6 and we are left with 2x = 6 which is a one step equation.

To get x by itself, since it's being multiplied by 2, we just divide both sides of the equation by 2. On the left, the 2's cancel and we are left with x. On the right, 6 over 2 simplifies to 3.

Therefore, our answer is x = 3.

After 3 months, plant A will be 14.2 centimetres tall and plant B will be 12.7 centimetres tall.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.

To find when to plant A will exceed the height of plant B, we need to set up an equation:

Let t be the number of months, then the height of plant A after t months is:

Height of plant A = 4.7 + 3.5t

The height of plant B after t months is:

Height of plant B = 5.2 + 2.5t

We want to find when to plant A will exceed the height of plant B, so we need to solve the equation:

4.7 + 3.5t = 5.2 + 2.5t

Simplifying, we get:

t = 1.0

Therefore, plant A will exceed the height of plant B after 1 month.

To find the heights of the plants after 3 months, we substitute t = 3 into the equations:

Height of plant A = 4.7 + 3.5(3) = 14.2 centimeters

Height of plant B = 5.2 + 2.5(3) = 12.7 centimeters

Therefore, after 3 months, plant A will be 14.2 centimetres tall and plant B will be 12.7 centimetres tall.

Final answer:

After solving linear equations for growth over time, Plant A will exceed the height of Plant B after 1 month. After 3 months, Plant A will be 15.2 cm tall and Plant B will be 13.7 cm tall.

Explanation:

The question involves two plants with different initial heights and growth rates. To find out when Plant A will exceed the height of Plant B and their heights after 3 months, we can use linear equations.

Calculation for Exceeding Height:

Let x represent the number of months it will take for Plant A to exceed the height of Plant B. The equation for Plant A's height over time is:

Height of Plant A = 4.7 + 3.5x (in centimeters)

The equation for Plant B's height over time is:

Height of Plant B = 5.2 + 2.5x (in centimeters)

To find out when Plant A exceeds Plant B, we set the equations equal and solve for x:

4.7 + 3.5x = 5.2 + 2.5x

Solving for x, we find that x = 1. Therefore, after 1 month, Plant A will exceed the height of Plant B.

Heights After 3 Months:

Height of Plant A = 4.7 + 3.5(3) = 15.2 cm

Height of Plant B = 5.2 + 2.5(3) = 13.7 cm

Elliot will make 4 hats and 16 scarves

Step-by-step explanation:

Let x be the number of hats and y be the number of scarves Elliot will make.

Elliott wants to make a total of 20 items, then

x + y = 20

Each hat uses 0.2 kilograms of yarn, so x hats use 0.2x kilograms of yarn and each scarf uses 0.1 kilogram of yarn, then y scarves use 0.1y kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats, then

0.1y = 2(0.2x)

Thus,

0.1y = 0.4x

y = 4x

Substitute it into the first equation:

x + 4x = 20

5x = 20

x = 4

y = 20 - 4

y = 16

Hence, Elliot will make 4 hats and 16 scarves
