Answer:
D. It's like multiplying a fraction by -1: it multiplies only the numerator
It’s B because multiplying any number by one equals the other number so therefore, 6 x -1 (meaning the negative sign before the parentheses) equals -6 and -7 x -1 equals 7 because a negative plus a negative equals a positive.
Integer rules are key here!!

Answer:
0.083 or 8.3%
Step-by-step explanation:
Since there are initially four cards, each card has a 25% (or 1/4) chance of being chosen. So the 8 card would have a 1/4 chance of being chosen.
Since the first card was chosen and not put back into the deck, the percent chance of each chosen card changes from 25% to about 33.3% (or 1/3) chance of being chosen. So the 8 card would now have a 1/3 chance of being chosen.
Since the question is asking what the percentage of choosing an 8 twice without replacing it is, you would multiply each of the percent chances that 8 card has to be chosen. In this case, multiply 1/4 and 1/3
This will result in about 0.083. To change to a percentage, multiply by 100 and the answer will end up at 8.3%.
Answer: 0%
Step-by-step explanation:
If you pick a 8 the first time, and you don't put it back, then there is no chance to get a 8 the second time. However, fi you pick a number other than 8 the first time, and pick 8 the second time, you didn't get 8 both times. Hope this helps!

What is a scatter plοt?
A scatter plοt is a graph that displays values fοr twο variables as οrdered pairs οf data pοints, with οne variable οn the hοrizοntal axis (x-axis) and the οther variable οn the vertical axis (y-axis).
Tο determine which twο pοints a line οf fit wοuld gο thrοugh tο best fit the data in a scatter plοt, we need tο lοοk fοr the pοints that are clοsest tο the general trend οr directiοn οf the pοints. In this scatter plοt, it appears that the general trend is a dοwnward slοping line.
The twο pοints that wοuld best fit this trend are (1, 9) and (10, 1), which are lοcated at the twο ends οf the scatter plοt and appear tο be the farthest frοm the general trend. Therefοre, the answer is:

Gusto's Department Store offers gift-wrapping services to their customers, and the manager at Gusto's needs to order more ribbon. Small gift boxes use 21 inches of ribbon, while large ones use 30 inches of ribbon. The manager at Gusto's expects to sell 200 small boxes and 220 large boxes this month. If the ribbon they use is sold by the yard, how many yards of ribbon should the manager order?
Answers
Answer: 300 yards of ribbon
Step-by-step explanation:
First of all, because we are working with inches, and need to find an answer in yards, we need to know how many inches are in a yard.
There are 36 inches in a yard.
Next, we need to multiply 21 inches by 200 small boxes, and 30 inches by 220 large boxes. We do this to find out how many inches of ribbon Gusto's needs for each size box.
The products are are 4,200 small boxes, and 6,600 large boxes.
The products (the answers to the multiplication problems) them need to be added together. We do this because we need to find how much total ribbon the manager of Gusto's needs to order.
The sum (the answer to the addition problem) of 4,200 + 6,600 = 10,800.
Lastly, we divide 10,800 by 36 (remember there are 36 inches in a yard). We do this to find the number of total yards of ribbon the manager will need to order for the month.
The quotient (the answer to the division problem) is 300.
Our answer is 300 yards of ribbon.

A swimmer can complete 1 lap across a pool in 1/3 minute. If she maintains that pace, how many laps will she have completed in 10 minutes?
Will it be less than or greater than 10?
Answers
Answer: If the swimmer can complete 1 lap across a pool in 1/3 minute, she can complete 3 laps in 1 minute.
In 10 minutes, she would complete:
3 laps/minute x 10 minutes = 30 laps
Therefore, the swimmer will have completed 30 laps in 10 minutes if she maintains that pace.
Since 30 laps is greater than 10, it means that the swimmer will complete more than 10 laps in 10 minutes.
Step-by-step explanation:
Greater than 10, because she swims 3 laps in each minute.

The requried surface area of the given prism is 1716 square centimeters.
What is the surface area?The surface area is the total area that covers the surface of a three-dimensional object. It is calculated by adding up the area of all the faces or surfaces of the object. For example, the surface area of a cube can be calculated by adding up the areas of all six faces.
Here,
The surface area of the given prism is given as:
Surface area = 5*20 + 10*20 +20*8 + 11*20+2[5*10+16*8]+16*20+20*18

The base of a right triangle is 2 inches less than 4 times its height, h. To create a new triangle, the length of the base is increased by 7 inches, and the height is increased by 5 inches. Which function represents the area, f(h), of the new triangle?
Answers
Answer:
see below
Step-by-step explanation:
Base b = 4h-2
new Base = b+7 =4h+5
new Height = h+5

Triangle NMO is drawn with vertices N(−4, −2), M(−1, −1), O(−4 , −5). Determine the image coordinates of N′M′O′ if the preimage is translated 7 units to the left.
N′(3, −2), M′(6, −1), O′(3, −5)
N′(−4, −9), M′(−1, −8), O′(−4, −12)
N′(−4, 5), M′(−1, 6), O′(−4, 2)
N′(−11, −2), M′(−8, −1), O′ (−11, −5)
Answers
Answer:
Triangle NMO has vertices N(-4,-2), M(-1,-1), and O(-4,-5). To translate the triangle 7 units to the left, we subtract 7 from the x-coordinate of each vertex. This gives us:
N' = (-4 - 7, -2) = ( -11, -2)
M' = (-1 - 7, -1) = (-8, -1)
O' = (-4 - 7, -5) = (-11, -5)
So the image coordinates of N'M'O' are N'(-11, -2), M'(-8, -1), and O'(-11, -5). Therefore, the answer is D. N′(−11, −2), M′(−8, −1), O′ (−11, −5).

A right rectangular prism has a height of 17.5 centimeters. The area of the base of the prism is 18 square centimeters. What is the volume, in cubic centimeters, of the right rectangular prism? (6.GM.2)
Answers
The volume of a right rectangular prism is given by the formula V = lwh, where l, w, and h represent the length, width, and height of the prism, respectively. Since the prism is right and rectangular, the length and width are perpendicular to each other.
We are given that the height of the prism is 17.5 centimeters and the area of the base is 18 square centimeters. Since the base is rectangular, we can find the length and width by dividing the area by one of the dimensions and multiplying by the other. Let's say the length is x and the width is y, then:
xy = 18 (area of base)
y = 18/x (solve for y)
Now, we can substitute the value of y in terms of x into the formula for the volume:
V = lwh = xyh = (18/x)(x)(17.5) = 315 cubic centimeters
Therefore, the volume of the right rectangular prism is 315 cubic centimeters.
