If you have to find Lateral Superficial Area just do P (perimeter of base) * h

So (8+19+10+7) * 8 = 44*8 = 352 cm^2

If you have to find Total Superficial Area the formule is LA + 2[(B+b)*h/2]

TA = 352 + 2[(19*8)/2] = 352+2(76) = 352+152 = 504 cm^2

Choose the correct domain and range for the following graph: <br><br> GUYS PLZ HELP !!!

algol [13]

The last choice, do an is the x value so you would look at the x values which is -4, 6. And range is the y values so the highest y value and the lowest. Which is -5,4. So you answer is the last option

Melissa bought 3 loaves of freshly baked bread at a specialty bread shop. She paid twice as much for the whole grain bread as fo

Ghella [55]

Answer:

The equations which describe this situation are:

C. f + (2f) + (2f + 2.50) = 11.25

E. 5 f = 8.75

Step-by-step explanation:

Here, the number of loaves of bread purchased = 3

The price of a loaf of French bread = f

The price of whole grain bread = 2 x ( Price of the french bread)

= 2 x (f) = 2 f

The price of cinnamon raisin bread

= ( Price of the whole grain bread) + $2.50

= 2 f + $2.50

Also, the total price paid for the 3 loaves of bread = $11.25

⇒ The cost of ( French + whole grain + Cinnamon raisin) bread = $11.25

or, f + (2f) + (2f + 2.50) = 11.25

or, 5 f = 11. 25 - 2.50 = 8.75

or, 5 f = 8 . 75

Hence the equations which describe this situation are:

C. f + (2f) + (2f + 2.50) = 11.25

E. 5 f = 8.75

A painting without its frame has a width 2.5 times its height, h, in inches. Its frame is 3 in. wide all along its perimeter. Wh

Lena [83]

Answer:

You will not be able to find the area of the framed painting without finding the length, which you did not provide. Assuming you meant “3 inches wide” to actually mean the length then the surface area of the painting is 9 inches squared. However, to find the height, you must divide 3 by 2.5 as the width was said to be 2.5 times the height of the painting. This will give you an answer of 1.2 inches in height.

Li uses 8.4 grams of sugar every day in her tea. Sue uses 12.6 grams of sugar every day in her coffee. If Li’s sugar canister co

podryga [215]

Answer:

They will have the same amount of sugar in their canisters in 15 days

Step-by-step explanation:

Here in this question, we are concerned with knowing the number of days in which the amount of sugar in both canisters will be the same.

Since we do not know the number of days it will

take, we have to represent it using a variable.

Let the number of days be x days

Now, we are told Li uses 8.4 g per day.

So in x days, the amount user will be 8.4 * x = 8.4x g

Thus, the amount of sugar remaining in her canister after x days will be 128 - 8.4x

For Sue, she uses 12.6 grams each day. So in x days, the amount of sugar used will be 12.6 * x = 12.6x g

So the amount of sugar left in her canister will be 191-12.6x

Since on the xth day , the amount of sugar remaining is same, we can equate the amount of sugar remaining in both canisters. That would be;

128-8.4x =191-12.6x

Collect like terms;

12.6x-8.4x = 191-128

4.2x = 63

x = 63/4.2

x = 15 days
