Roland wants to buy a jacket that is discounted 20% off the regular price. Which of the following is NOT a valid way to determine the amount of the discount?

A
Move the decimal point of the original price one place to the left and then double it.

B
Set up a proportion with the ratio of the original price to the amount of the discount equal to the ratio 20 to 100.

C
Multiply the original price times 0.2.

D
Divide the original price by 5.

Answers

C would be the answer because if you multiply 10 x 0.2 you will get 2 but if it is 20% off you would’ve gotten 5

Nisha has invited a group of friends over for a spaghetti dinner. There will be eight people dining, and Nisha would like to prepare 1 1/2 cups of cooked spaghetti per person. How many 16 oz. packages of dry spaghetti must Nisha use, and in how much water should she cook the pasta?

Remember, it takes 4 oz. of dry spaghetti to produce 2 cups of cooked spaghetti, and each 4 oz. of dry spaghetti requires 1 quart of water.

Answers

2 dry packages of spaghetti and 6 quarts of water. If 4 oz. equals 2 cups, then 3 oz. equals 1 1/2 cups of spaghetti. I multiplied the 3 oz. by the eight guests and got 24. Then, I took the 24 oz and divided that by 4 to get the quarts of water.

Answers

Answer:

summary

Step-by-step explanation:

Answer: Choice C

To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)

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

Explanation:

The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.

The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,

slope = rise/run = (change in y)/(change in x)

Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.

Kimi’s dog gives birth to a litter of 4 puppies per year, on average. The relationship between time and the expected total number of puppies is shown on the graph. Which other ordered pairs would fall on this line? Select all that apply.
(0, 0)
(2, 6)
(3, 12)
(4, 14)

Answers

Answer:

(0,0) and (3,12)

Step-by-step explanation:

The ordered pairs that would fall on the line are (0, 0), (1, 4), (2, 8), (3, 12), and (4, 16).

As shown in the graph,

x-axis represents the number of years

y-axis represents the number of puppies.

The slope of the line is 4, which means that for every 1 year that passes, the number of puppies increases by 4.

The y-intercept of the line is 0, which means that if there are 0 years, then there are 0 puppies.

The ordered pairs (2, 6) and (4, 14) do not fall on the line because they do not follow the slope of the line.

For example, in the case of (2, 6), the number of puppies should be 8, not 6.

Therefore, the only ordered pairs that would fall on the line are (0, 0), (1, 4), (3, 12), and (4, 16).

What is the circumference of Circle O?

Answers

Answer:

[tex]14\pi[/tex]

Step-by-step explanation:

The formula for finding the circumference of a circle is 2 times pi times the radius.

Looking at the picture, we can see that the radius of the circle is 7 cm. Plugging that into the formula gives:

2*[tex]\pi[/tex]*7 = 14[tex]\pi[/tex]

Answer: 14π cm or 43.98 cm.

Step-by-step explanation: To find circumference, one must use the equation c = 2πr (c = circumference and r = radius). Plugging in the values, we get 2πr = 2*π*7 which = 14π or if you want it rounded: 43.98 cm.
