Step-by-step explanation:

cookies: $48 (24x2)

muffins: $13 (13x1)

lemonade: 144 (36x4)

144+13+4=$205

Answer:

205

Step-by-step explanation:

COOKIES: 2x24= 48

MUFFINS: 1x13= 13

LEMONADE: 4x36= 144

144+ 48+ 13= 205

written answer:

The answer is 244 i got this answer by mulitplying how much he sold by the prices he sold by.So i multiplied 2x24 for the cookies and got 48, then i multiplied the muffins 1x13 to get 13.Finally i multiplied 4x36 to get 144 after that, i added all the sums up and i got the answer 205.

Lucy has 68 books.
This number of books is 70% more than the number of books she had last year.
How many books did Lucy have last year?

Answers

Answer:

Lucy had 40 books last year.

Step-by-step explanation:

assuming 100% is the percent;

100% + 70%

100 : x

170 : 68

cross multiply = 170x = 100 x 68

-------- ————-

170 170

cancel 170/170

therefore x = 100 x 68 divided by 170

result is 40

The number of books that Lucy has last year will be 40 books.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Lucy has 68 books. This number of books is 70% more than the number of books she had last year.

Let 'n' be the number of books. Then the equation is given as,

1.7 n = 68

n = 68 / 1.70

n = 40

The number of books that Lucy has last year will be 40 books.

Step-by-step explanation:

Which statements are true regarding the sides and angles of the triangle? Select three options. Line segment X Y is the longest side. Angle X is the largest angle. Angle Z is greater than angle Y. Line segment X Z is opposite the largest angle. Line segment X Z is the shortest side.

Answers

Answer:

B. Angle X is the largest angle.

C. Angle Z is greater than angle Y.

E. Line segment X Z is the shortest side.

Step-by-step explanation:

YZ = 2n, XZ = n - 2, XY = n + 4 and n ≥ 5.

YZ - XZ = 2n - (n - 2) = n + 2. but n ≥ 5, hence YZ - XZ = n + 2 ≥ 7.

YZ > XZ

YZ - XY = 2n - (n + 4) = n - 4. but n ≥ 5, hence YZ - XY = n - 4 ≥ 1

YZ > XY

XY - XZ = n + 4 - (n - 2) = 6: XY > XZ

Therefore:

YZ > XY > XZ

The angles are proportional to their opposite sides, hence:

∠X > ∠Z > ∠Y

A. Line segment XY is the longest side.

This is wrong because YZ is the longest side.

B. Angle X is the largest angle.

This is correct. ∠X is the largest angle because it is opposite to the longest side (YZ)

C. Angle Z is greater than angle Y.

This is correct. ∠Z is opposite to the side XY while ∠Y is opposite to the side XZ

D. Line segment XZ is opposite the largest angle.

This is wrong. ∠X is the largest angle which is opposite to the longest side (YZ)

E. Line segment X Z is the shortest side.

This is correct

im on the last question of my test and I need help. what table represents a linear function??

Answers

Answer:

d is right guy below me is right because this one has a partern

because everytime it was going -2 for y and +1 for x

Answer:

D is the answer

Step-by-step explanation:

For a table to be linear, you can look at the y and x. The equation for slope if ∆y/∆x. Basically, look at the change in y over the change in x. In the last equation, the rule for y cotinues to be -2. X changes as +1. This is a pattern that continues. If you put the y/x, the slope would be -2.

Also, if you look at the other equations, there is no rule. Therefore, the answer is D.

Independence Movements in AfricaBetween 1957 and 1993 nearly 50 African states achieved independence from colonial rule. The first sparks of resistance to foreign control took shape much earlier, though, in some cases hundreds of years earlier. Independence movements developed throughout Africa in the mid-1900s. Although they followed different paths, they shared a common beginning: resistance to domination by foreign powers. Unfortunately, once in control, many of these independence movements imposed their own form of domination. As a result, modern Africa continues to wrestle with many of the same political problems that motivated the independence movements of the past.Describe the common trigger for the indepedence movements in Africa. Read this excerpt from The Medicine Bag. He carefully prepared for his quest with a purifying sweat bath, and then he went alone to a high butte top to fast and pray. After three days he received his sacred dreamin which he found, after long searching, the white mans iron. He did not understand his vision of finding something belonging to the white people, for in that time they were the enemy. When he came down from the butte to cleanse himself at the stream below, he found the remains of a campfire and the broken shell of an iron kettle. This was a sign that reinforced his dream. He took a piece of the iron for his medicine bag, which he had made of elk skin years before, to prepare for his quest. He returned to his village, where he told his dream to the wise old men of the tribe. They gave him the name Iron Shell, but neither did they understand the meaning of the dream. The first Iron Shell kept the piece of iron with him at all times and believed it gave him protection from the evils of those unhappy days. Then a terrible thing happened to Iron Shell. He and several other young men were taken from their homes by the soldiers and sent far away to a white mans boarding school. He was angry and lonesome for his parents and the young girl he had wed before he was taken away. At first Iron Shell resisted the teachers attempts to change him, and he did not try to learn. One day it was his turn to work in the schools blacksmith shop. As he walked into the place, he knew that his medicine had brought him there to learn and work with the white mans iron. Iron Shell became a blacksmith and worked at the trade when he returned to the reservation. All of his life he treasured the medicine bag.
