Which of the following expressions could be used to find the sale price of an item that costs d dollars if it is on sale for 30% off?
0.7 d
0.3 d
30 d
70 d

Answers

Answer:

0.3 d

Step-by-step explanation:

A percent is basically the percent over 100

In this case, the item is 30% off so you can write 30% as a fraction like the following:

30/100

Now we can convert that to decimal

30/100 is also 0.30

Since there is no need for the extra zero in this case

the answer for this question is:

0.3 d

Answer: 0.3d should be correct

Answers

Answer:

Step-by-step explanation:

The time goes up by 1 every time and the distance goes up by 500 every time. Lets lok at the relationship:

As seen in the graph, every minute she goes 500 ft. Theoretically, if we take half of the time to run then we must take half of the distance. This can be described as a distance/time relationship. So now with that knowledge, we loot at the 10-minute mark; she's currently at 5,000 feet so if she goes half the time more we are adding half the feet she runs per minute (250ft). Therefore the answer is 5,250 feet since we are adding 250(half the time she runs per minute) to 5,200 feet(how much she ran in 10 minutes)

Hope this helps

For this, you simply switch the x and y values places and then change the symbol of the new y-axis.
A(-3,0) = A’(0,3)
B(-2,4) = B’(4,2)
C(1,-1) = C’(-1,-1)
Subtract 3 from the y-axis
A’(0,3) = A”(0,0)
B’(4,2) = B”(4,-1)
C’(-1,-1) = C”(-1,-4)

On a winter day, the low temperature in Anchorage was 23 degrees below zero, (in Celsius) and the low temperature in Minneapolis was 14 degrees below zero (in Celsius). Sophia wrote, Minneapolis was colder because: -14 < -23

Is Sophia correct? Explain your answer.

Answers

Answer:

Sophia is incorrect

Step-by-step explanation:

This is because if you looked a number line, -14 is closer to 0 than -23. So.. -14>-23

It is 37 because u do 23-23 which gives you 0, then you take away 0 and go down until -14, 23+14=37 so it is 37 Degrees Difference.

Answer: 22ft^3

Step-by-step explanation:

First, find the volume of the little cubes that the rectangular prism can hold inside of itself.

The formula for volume of a rectangular prism is:

V = length x width x height.

= 1/2 x 1/2 x 1/2

= 1/8

Now, since the rectangular prism can hold 176 of these cubes, you need to multiply each cubes volume, 1/8, by 176. 1/8 x 176 = 22

Therefore, the volume of the box is 22ft^3

Find the volume of the cone. Round your answer to the nearest tenth.

A cone is shown. Its height is 4 inches and the radius of the base is 2 inches.

The volume of the cone is about __cubic inches.

Answers

Step-by-step explanation:

= 56.5148 cubic inches

If you divided 26 objects into sets of 6, how many sets of 6 could you make, and how many are left over?

Options:
A. 2 sets with 4 left over
B. 4 sets with 2 left over
C. 3 sets with 3 left over

Answers

Answer:

B. 4 sets with 2 left over

Step-by-step explanation:

We have to find out how many times 6 can go into 26. We know that 6 times 4 is equal to 24, so we know that 6 can go into 26, 4 times.

Now we have to figure out how many are left over. To do that, lets subtract 26 minus 24, which equals 2.

Therefore, the answer is B, 4 sets with 2 left over.

I hope this helps!!! Have a lovely day! :)

the answer would be 2 sets with 4 left over
