Find the surface area of the prism

Answers

Answer 1

Answer:

324m

Step-by-step explanation:

16 x 3 = 48

6 x 3 = 18

6 x 16 = 96

48 + 18 + 96 = 162

162 x 2 = 324

Add these all up and then multiply by 2, since there are 2 equal sides on this prism.

Answer 2

Answer:

324

Step-by-step explanation:

also sorry if it makes no sense.

Area = 2 ( Lw + Wh + HL )

( Length width + Width height + Height length ) x 2

basically find the area to the front three squares and then multiply them by two, but correct me if that's not how your curriculum works! :)

What is the value of x+y?

Eight grade math

Answers

Hello! The value of x+y is 12

Make sure to read an explanation so you can understand the solution better.

Any questions about the answer and explanation can be asked through comments.

Step-by-step explanation:

We can simply solve the system of equations by substituting x = 3y in the first equation

[tex] \large{2x + 2y = 24} \\ \large{2(3y) + 2y = 24} \\ \large{6y + 2y = 24} \\ \large{8y = 24} \\ \large{y = 3}[/tex]

Therefore, the value of y is 3. Then we substitute the value of y in x = 3y.

[tex] \large{x = 3y} \\ \large{x = 3(3)} \\ \large{x = 9}[/tex]

Therefore, the value of x is 9.

Since you want to find x+y, simply add 9 and 3 as we get 12.

Therefore x+y = 12.

A rectangular barn measuring 14 feet b 10 feet is located in one corder of a fenced area. Robert ties his cow to the corner of the barn so the animal can graze anywhere within the circular area outside the barn and fence. If the cow is tied with a 24 ft rope, approximately how much grazing area does the cow have?

Answers

For this problem you would be solving for the area of 3/4 of a circle with the radius being 24ft. So area of a circle is a= PI R squared so plug in 3.14(24)squared order of operations says to square first so 24 squared is 576. Then PI or 3.14 times 576 equals 1808.64
Now because it is only 3/4 of a circle you wil multiply the answer by 3/4 which is 1,356.48 ft. So the Cow has 1,356.48 Ft of grazing area.

If when the cow is tied with a 24 ft rope, So approximately, The Cow has 1,356.48 Ft of grazing area.

Calculation of Circular area

For this situation, you would be translating for the area of 3/4 of a circle with the radius being 24ft.

So the area of a circle is a is = PI R squared so plugin 3.14(24) squared order of functions says to square first so 24 squared is 576.

Then PI or 3.14 times 576 equals 1808.64

Now because it is exclusively 3/4 of a circle you will reproduce the response by 3/4 which is 1,356.48 ft.

Therefore, The Cow has 1,356.48 Ft of grazing area.

Christiana and Marlena opened their first savings accounts on the same day. Christiana opened her account with $55 and plans to deposit $10 every month. Marlena opened her account with $20 and plans to deposit $15 every month. After how many months will their two accounts have the same amount of money? What will that amount be?

The two accounts will have the same amount of money in BLANK months. And, the amount will be $ BLANK

Answers

Answer: it will take 4 months for the amount to be the same and the amount would be $95

Step-by-step explanation:

Let x represent the number if months it will take for the two accounts have the same amount of money.

Christiana opened her account with $55 and plans to deposit $10 every month. This means that the amount that in the account after x months would be

10x + 55

Marlena opened her account with $35 and plans to deposit $15 every month. This means that the amount that in the account after x months would be

15x + 35

For the amount in the accounts to be the same, the number of months would be

15x + 35 = 10x + 55

15x - 10x = 55 - 35

5x = 20

x = 20/5

x = 4

The amount would be

15 × 4 + 35

= 60 + 35

= $95

it will take 4 months for the amount to be the same and the amount would be $95

Answer:

[tex] \frac{2}{15} [/tex]

x+10

Step-by-step explanation:

we know the y-intercept : (0,10)

picking another point on the line, (2,25)

finding slope is

[tex] \frac{y2 - y1}{ x2 - x1} [/tex]

so inserting that together is:

[tex] \frac{2 - 0}{25 - 10} [/tex]

that equals to,

[tex] \frac{2}{15} [/tex]

and since we already have the y-intercept you take the 10 to replace the b in the equation y=x+b

meaning x = slope and b = y-intercept

equation all together

y =

Write a unit rate for the situation.
$12.50 for 5 ounces

Also if you can, with your answer can you tell me how to find unit rate?

Answers

Answer:

$2.50 for 1 ounce

Step-by-step explanation:

I hope this helps

Answer:

The correct answer is $2.50.

Step-by-step explanation:

The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.

We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.

To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:

12.50 / 5 = 2.50

In this way we can verify that the unit price of 5 ounces

Answer:

The answer would be 2691 meters.

Step-by-step explanation:

When looking at the figure, since you know the length of all of the sides you can easily cut it into three simpler rectangles by extending the line of 23 meters out to either side.

This gives us three rectangles by the measures of 23 by 12, 23 by 12, and 31 by 69.

In order to calculate area you do equation A=LxW

In this case, Area=(23) x (12)

This will get you the answer 276 meters.

Do this again for the other rectangle that measures 23 by 12, and add the two areas together.

This gives you 552 meters.

To find the area of the remaining triangle, once again do A=LxW

Area=(31) x (69)

This will give you 2139 meters.

Sue earns $6 an hour walking her neighbor's dog.

Part B: List three ordered pairs to show the values of the two variables. (3 points)

Part C: Write an equation to represent the relationship between the two variables. (3 points)

Answers

is that all that the question says ?

(A) The independent variable is time because it is something that can be controlled and changed by the person walking the dog.

(B) Three ordered pairs are (1, 6), (2, 12), (0.5, 3).

Money earned = 6t

What is an expression?

In mathematics, an expression is a combination of numbers, variables, and operations that are grouped together to represent a mathematical statement.

Part A:

In this situation, the two variables are:

Independent variable: Time (in hours) spent walking the dog

Dependent variable: Amount of money earned (in dollars)

The independent variable is time because it is something that can be controlled and changed by the person walking the dog. The dependent variable is the amount of money earned because it is directly affected by the amount of time spent walking the dog.

Part B:

Here are three possible ordered pairs to show the values of the two variables:

(1, 6) - Sue earns $6 for walking the dog for 1 hour.

(2, 12) - Sue earns $12 for walking the dog for 2 hours.

(0.5, 3) - Sue earns $3 for walking the dog for half an hour (30 minutes).

Part C:

The relationship between the two variables can be represented by the equation:

Money earned = Hourly rate x Time spent walking

In this case, the hourly rate is $6 and the time spent walking is represented by the variable "t". Therefore, the equation is:

Money earned = 6t

where "t" is the time (in hours) spent walking the dog and "6t" is the amount of money (in dollars) earned for that time.

When I was about fifteen years old we had retired to our house near Belrive, when we witnessed a most violent andterrible thunderstorm.
