Answers

Answer 1

Answer:

A. 2.25

Step-by-step explanation:

-3x + 10 = 5x - 8 (Given)

10 = 8x - 8 (Added 3x on both sides)

18 = 8x (Added 8 on both sides)

2.25 = x (Divided 8 on both sides)

PLEASE HELP THIS IS TIMED!!!!!!!!!!!!!!!!!!!! A gumball machine had 78 gumballs. Each person who put a coin into the machine gets 3 gumballs. After a certain number of people got gumballs, there were 54 gumballs remaining. Estimate how many people got gumballs out of the machine.

Answers

Answer:

8 people got gumballs out of the machine.

Step-by-step explanation:

Given that:

Number of gumballs in machine = 78

Number of gumballs on each coin = 3

Number of gumballs left = 54

Let,

x be the number of people who put coin

Gumballs left = Total gumballs - 3*Number of people

54 = 78 - 3x

3x = 78 - 54

3x = 24

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{24}{3}\\x=8[/tex]

Hence,

8 people got gumballs out of the machine.

Find the solution set of the following equations:

2y=2x+7

X=y+2

Answers

Answer:

The system of equations has no solution.

Step-by-step explanation:

Given the system of equations

2y = 2x+7

x = y+2

solving the system of equations

[tex]\begin{bmatrix}2y=2x+7\\ x=y+2\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}2y-2x=7\\ -y+x=2\end{bmatrix}[/tex]

Multiply -y+x=2 by 2:  -2y+2x=4

[tex]\begin{bmatrix}2y-2x=7\\ -2y+2x=4\end{bmatrix}[/tex]

so adding

[tex]-2y+2x=4[/tex]

[tex]+[/tex]

[tex]\underline{2y-2x=7}[/tex]

[tex]0=11[/tex]

so the system of equations becomes

0 = 11 is false, therefore the system of equations has no solution.

The area of the given triangle ABC is 61.8 Square units.

What is the area of a triangle?

The entire area filled by a triangle's three sides on a two-dimensional plane is referred to as the triangle's area.

Given that, a triangle ABC. whose side AC is 10 and BC is 13. and two angles ∠ACB and ∠BAC are 72° and 64° respectively. since area of a triangle = 1/2 * multiple of two sides * sin(angle made by those side)

Hence,

area of triangle ABC = 1/2 * AC * BC *sin(∠ACB)

Area of the triangle = 1/2 * 10 * 13 * sin 72° = 61.8

Therefore, the area drawn by the given triangle ABC is 61.8 square units.

The area of the triangle is A = 61.8 units²

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now ,  length of side AC is 10 and the length of CB is 13.

Angle BAC is 64° and angle ACB is 72°

Now , the area of the triangle is A = ( 1/2 ) x Length x Base ( sin 72° )

A =  1/2 ( 10 ) ( 13 ) sin 72°

A =  61.8 units²

Hence , the area is A = 61.8 units²

One of the tokens for a board game is a circle with a radius of 15 millimeters. Which measurement is closest to the circumference of the token in millimeters?

Answers

Answer:

The circumference of the circle is approximately 92 mm

Step-by-step explanation:

For us to be given the radius of the tokens it is safe for us to make the assumption that the token is circular in shape. Thus, we can solve the problem using various theories in circle geometry.

We will use the circumference equation to estimate the circumference of the circle, assuming the value of π is = 3.14

The circumference of a circle can be given as 2 X π X radius

This will be 2 X 3.142 X 15 = 94.247 ≈92mm

Therefore, the circumference of the circle is approximately 92 mm

Cheddar cheese costs $3.45 per pound. Which equation best represents the total cost, c, of pounds, p, of cheddar cheese?

Answers

Answer:

c = 3.45 * p

Step-by-step explanation:

Since the total cost of Cheddar Cheese is dependant on the number of pounds that are being purchased then to calculate the total cost we would need to multiply the price per pound by the number of pounds being purchased. Therefore, the following equation would best represent the total cost of the cheddar cheese...

A factory makes 640brushes in 4 hours.Does the equation y=150x model the number of brushes made each hour?

Answers

Answer:

No it doesn't

Step-by-step explanation:

The equation we have is

Y = 150x

We have x = 4 hours

This is a simple question. We have to plug in the x = 4 in the equation to find out if we would have 640 brushes. If y = 640, then it models it. But if y is not equal to 640, it doesn't.

So let's solve this to see for ourselves.

Y = 150(x)

We put the value of x

Y = 150(4)

Y = 600

So we can see that the equation does not model the number of brushes made each hour. This equation models 600 brushes and not 640.

1. Estimate how many minutes you talk on your cell phone every month________(you can randomly pick) 2. Which plan above do you think will result in the cheapest plan for you? Why do you think so?

Answers

Problem 1

This answer will vary from person to person. And as your teacher says, you can also randomly pick a value if you aren't sure.

Let's say you spend an hour each day talking on your phone. This means voice calls and not texting. Video calling could also be part of voice calling, though it will depend on how your cell phone company structures the cell phone plan.

Anyways, let's go with 1 hour. This converts to 60 minutes.

If you talk for 60 minutes per day, then you spend 60*30 = 1800 minutes per month talking on the phone. This is an average value. I'm using 30 days per month.

Answer: 1800 minutes

=====================================================

Problem 2

For each of the 6 companies, form their respective equations

x = number of minutes

y = total cost per month

We get the following equations for each company:

Rogers (all day plan): y = 0.25xFido: y = 0.20xTelus: y = 0.35xRogers (MY5 Prepaid): y = 0.25x+20Bell: y = 0.10x+10Public Mobile:  y = 0x+24 which simplifies to y = 24

With those 6 plans in mind, we will plug x = 1800 into each equation

Doing so leads to...

Rogers (all day plan): y = 0.25x = 0.25*1800 = 450Fido: y = 0.20x = 0.20*1800 = 360Telus: y = 0.35x = 0.35*1800 = 630Rogers (MY5 Prepaid): y = 0.25x+20 = 0.25*1800+20 = 470Bell: y = 0.10x+10 = 0.10*1800+10 = 190Public Mobile:  The monthly cost is $24 a month regardless of how many minutes you use. This is an unlimited minutes plan.

So we can see that clearly Public Mobile has the lowest cost per month at $24 a month. The cost per minute of $0 means that we have unlimited minutes here. The other costs are really high and far from $24. The next smallest value is $190, which is far from $24.

Is Public Mobile always the best choice? It depends. Refer to the chart below (attached image) and you'll see that the yellow cells are instances when Public Mobile isn't the cheapest option. However, note how small x has to be for this to occur and note how the yellow cells don't show up very often. Sure we could make more yellow cells pop up if we used even smaller x values, but at a certain point, it's likely not to be realistic. Why have a cell phone plan if you don't use the minutes to talk on it? Of course, everyone is different.

Anyway, for the x value chosen in problem 1, the Public Mobile plan is the cheapest option at $24 per month.

Step-by-step explanation:

If we're gonna have some sort of increase each year, it's gonna pop up in our model attached to a variable, because it represents some kind of change, and variables can change. Looking at our equation, the 28.6 represents our starting point: the boy is 28.6 inches tall when he's 2 years old. The 3a term, then, represents the boy's increasing height each year. When he's 3 years old, a = 1, and so h = 3 + 28.6 = 31.6 inches. When he's 4, a = 2, and h = 3 + 31.6 = 34.6. The increase is always 3 inches.

Ginny is making homemade pizzas for her family. The recipe makes 70 ounces of dough, but she made more that to ensure she had enough to feed everyone. She plans to freeze 28 ounces for next week, and the rest of the dough will be split evenly to make 3 pizzas. A. Write an inequality to represent the maximum weight of each pizza. Response area b. Each of Ginny's pizzas will weigh more than Response area ounces.

Answers

Answer:

14 ounce

Step-by-step explanation:

Given that:

Ounces of dough used in making recipe = 70 ounces

Number of ounces frozen = 28 ounces

Number of pizzas made from dough left = 3

Number of ounces left = total made - number frozen

Number of ounces left = 70 - 28 = 42

Weight of pizza made :

Number of ounces left / number of Pizzas made

42 / 3 = 14

Hence, maximum weight of each pizza made will weigh more than 14 ounces
