How do you write 16/20 as a percentage​

Answer:

-14

Step-by-step explanation:

Well, the equation would be 8+2n=-20

2n=-28

n=-14

Answer:

2x + 8 + = 20

8 + 12 is 20 so x must be 6 i think

Answer:

look I have sent you the answer of your question.

This trinomial can be factored as two binomials.

So setup two sets of parenthses.

8x² can be factored as 8x · x or 4x · 2x

and -3 can be factored as +3 · -1, -1· +3, -3 · +1, or +1 ·-3.

If the middle term in the original trinomial is even,

try pairs of even factors first if you have that option.

In this case, we have a 4x and a 2x so let's try those first.

Let's do this with all the factors of -3.

So our first possible answer could be (4x + 3)(2x - 1).

Since the product of the outer terms, -4x, plus the product of the inner, 6x,

doesn't add to our middle term, this pair doesn't work.

Now let's try (4x - 1)(2x + 3).

The product of the outer terms, 12x, plus the product of the inner, -2x,

equals the middle term in our original trinomial, this pair works.

So our answer is (4x - 1)(2x + 3).

(ii) Two lines that have the same y-intercept intersect at exactly one point.

Conditionally true, two lines that have the same y-intercept intersect at exactly one point if and only if slopes are different. (Answer: True for some cases)

(iii) Two lines that have the same slope do not intersect at any point.

A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

The volume of a rectangular prism=Length X Width X Height

A company makes a greenhouse that is shaped like a rectangular prism on bottom and a half cylinder on top.

Given;

Base = 3m x 9m

Height of house = 2 m

Find: Volume of green house

Volume of green house = 3m x 9m x 2m

5280 cubic inches

Step-by-step explanation:

V= l * w * h

V= 18 * 12 * 20

V= 4320 cubic inches

Then do the first measurement subtracted by the second one because it wants to know the difference.

9600 - 4320 = 5280 cubic inches

The conversion factor is 454 grams / pound. That makes the answer D.

All of the answers have the right digits. It's the number of zeros that cause the problem.

Answer:

450 grams is the closest metric weight of 1 pound which in actuality is 453.592 gram.

The slope for this problem is -4/3.

Step-by-step explanation:

To find the slope, we can look at it as Rise/Run. The rise is how many units up (+) a point is or how many units down (-) a point is from the starting point. The rise is how many units to the left or right a point is from the starting point.

Now that we understand Rise/Run, we can find the slope. If we go from the highest point, or the point farthest to the left in the picture shown, we can see that we need to go four units down to get to the same level as the next point, so we would be moving -4 units away from the point. We can also see the second point is 3 units to left.

With this information, we can now figure out that the slope is -4/3.

Answer: area mean multiply

Step-by-step explanation:

Answer:

76 feet (Just put 76 in the answer box)

Step-by-step explanation:

Knowing the perimeter of a rectangle is 2l + 2w, multiply 2 by 3.5. Then multiply 2 by 4.5, and add them together.

2(3.5) + 2(4.5)

The two products would be 7 and 9 respectively.

7 + 9 = 16 feet of fencing for 1 rabbit pen.

We have 2 pens, so multiply 16 by 2.

The rabbit pens need 32 feet of fencing.

(Alternatively you could have done 2(2(3.5 + 4.5)).

2(2(8))

2(16)

32 ft of fencing (rabbit pens))

Now, add 12 and 10. Then multiply that by 2.

2(12 + 10)

2(22)

The garden needs 44 feet of fencing.

Now add 32 and 44 to get the total amount of fencing needed.

32 + 44

The rabbit pens and the garden need 76 feet of fencing. (Just put 76 in the answer box as the unit (feet) is already given.)

Answer:

It is A

Step-by-step explanation:

It starts from origin

The first graph represent the volume of water in a cylinder as a

function of its height.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The first graph with a straight line passing through the origin could represent the volume of water in a cylinder as a function of its height.

This is because the formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height.

If we keep the radius constant and vary the height, we can see that the volume of the cylinder increases linearly with the height. In other words, the volume is directly proportional to the height.

Since the line passes through the origin, this indicates that when the height is zero, the volume is also zero.

This is consistent with the fact that a cylinder with zero height has zero volume.

Hence, the first graph represent the volume of water in a cylinder as a

function of its height.
