Anthony is building a cube-shaped box to store some of his smaller crafting supplies. The formula for the surface area of a cube is SA=6s2, where s is the side length of the cube. If he has a total of 200 in.2 of cardboard, can Anthony build a box where s=6 in.?

No, he needs 16 in.2 more cardboard.

No, he needs 232 in.2 more cardboard.

Yes, he will have 56 in.2 of cardboard left over.

Yes, he will have 128 in.2 of cardboard left over

Answers

Answer:

No, he needs 16 inches^2 more cardboard.

Step-by-step explanation:

Take the formula and substitute values into it. 6 * 6^2

Do the exponent first to get 6 * 36, and then complete that to get 216. Since he has 200 inches of cardboard and he would need 216, that means he would need 16 more square inches to make his cube.

No he needs 16 in 2 more cardboard

What’s the answer and how do i find slope?

Answers

The answer would be m = -7

You can find the slope by putting the two ordered pairs into the formula: y2-y1/x2-x1.

y2 is the second y, being 8 in your case.

x2 is the second x. Being -2 in your case.

y1 is the first y, being -6 in your case.

x1 is the first x. Being 0 in your case.

After plugging in these numbers you will get 8- -6/-2-0. This will get you 14/-2. which will equal -7, the slope.


I can explain more if you want.

Hope this helped!! :)

Answer:

the answer should be -7

Step-by-step explanation:

you find slope by using the formula y2-y1/x2-x1

Given that, nine cyclists were each asked the distance in miles they biked last week. The distance travelled by 9 cyclists is 16, 8, 2, 6, 8, 11, 9, 15 and 7.

We need to complete the grouped frequency distribution for the data.

What is the grouped frequency distribution?

In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.

Now, the frequency distribution for the given intervals is as follows:

That is, for intervals 2 to 7 the frequency is 3.

For intervals 8 to 13 the frequency is 4.

For intervals 14 to 19 the frequency is 2.

Therefore, the grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Answers

Step-by-step explanation:

Okay, so the triangle would look something like this:

see the image attached

Since AB=AC, which is given; <ABD = <ACD, because they are the angles opposite from the congruent sides of the isosceles triangle; and <ADB=<ADC, as AD is the bisector*; ΔABD ≅ ΔACD using SAA/AAS (side-angle-angle) congruencey.

A = small box of oranges

B = large box of oranges

3A + 14B = 203

11A + 11B = 220

Take the second equation and divide it by 11 as both A and B have the same coefficient, which will equal:

[tex]\frac{11A+11B}{11}[/tex] = A + B

220 will also have to be divided by 11, giving you 20

A + B = 20

You can cancel out 3A in the first equation by subtracting 3A + 3B = 60 from it.

11B = 143

143/11 = 13

B (large box of oranges) costs $13.

Substitute 13 for B back into one of our equations, in this case 3A + 3B = 60

3A + 3*13 = 60

3A + 39 = 60

3A = 21

A = 7

Thus:

A small box of oranges costs $7, and a large box of oranges costs $13.

Fill in the next two terms in the pattern. Enter your answers in the boxes.



0.16, 0.35, 0.54,
,

Answers

Answer:

By substracting 0.16 from 0.35, we get 0.19. This is also true when we subtract 0.35 from 0.54. Thus, 0.19 is what we are adding to each previous term to get the next one. When we add 0.19 to 0.54, we get 0.73, and when we add 0.19 to 0.73, we get 0.92. Therefore, the next two terms in the pattern are 0.73 and 0.92.
