Answers

Answer 1

Answer:5r2+2

Step-by-step explanation:

Distribute the Negative Sign:

=4r2−3r+2+−1(−r2−3r)

=4r2+−3r+2+−1(−r2)+−1(−3r)

=4r2+−3r+2+r2+3r

Combine Like Terms:

=4r2+−3r+2+r2+3r

=(4r2+r2)+(−3r+3r)+(2)

=5r2+2

Remark

The standard area for a Triangle is

Area = 1/2 * b * h

Givens

b = 16

k = 1/2

h = 4

Solution

Area = 1/2 * b * h

Area = 1/2 * 16 * 4

( 15n2 - 5n + 45 ) ÷ 5​

Answers

I'm assuming we need to simplify this expression. (Tip when you are writing n squared, please write n^2, not n2.)

Since we can see that there is a 5 in each term inside the ( ), we simplify have to remove that if the whole thing is going to be divided by 5.

Answer:

(15n^2-5n+45)/5

=3n^2-n+9

Answer:

3n^2-n+9

Step-by-step explanation:

You would want to divide the 5 between each of the terms. 15n^2 ÷ 5 is 3n^2. 15 ÷ 5 is 3. The n^2 stays, so 3n^2. -5 ÷ 5 is -1. We don't have to worry about writing the -1. Rather, just write the -n, it is the same as writing -1n. Lastly, 45 ÷ 5 is 9. You have to put the terms together in standard form. Standard form is just writing the numbers from greatest power to least power. The 3n^2 would come first since 2 is the greatest power. Next would be the -n, and lastly the 9. The 9 is the constant, which always comes last. A constant would be a number without a variable after it, like 2x is not a constant but just 2 is. Therefore, the answer is 3n^2-n+9.

At a sale, coats were sold for $11 each. This price was 55% of a coat's original price. How much did a coat originally cost?

Answers

Answer:

The coat originally cost $20.

Step-by-step explanation:

The original cost is of x.

At a sale, coats were sold for $11 each. This price was 55% of a coat's original price.

This meas that:

[tex]0.55x = 11[/tex]

How much did a coat originally cost?

This is the solution for x for the equation above. So

[tex]x = \frac{11}{0.55} = 20[/tex]

The coat originally cost $20.

Answer:

20

Step-by-step explanation:

so when setting up you put 11/x=55/100 then cross multiply. then you should get 55x=1,100 .

divide 1,100 by 55 then you should get your answer which is

x=20 :)

what is the approximate diameter of a sphere with a volume 34 cm the third power?​

Answers

Answer:

Diameter = 4cm________________

Step-by-step explanation:

volume = 34cm³

volume = 4/3×π×radius³

34cm³ = 4/3 × 3.14 × radius³

34cm³ = 12.56/3 × radius³

radius³ = 34×3/12.56

radius³ = 8

radius = ³√8

radius = 2cm

diameter = 2×radius

= 2×2

= 4cm

11) Ron paid x dollars for a pair of jeans. Tim bought the same pair of jeans for
half the price as Ron. If they paid a total of $45 for the 2 pairs, how much did
each spend on their jeans?
PLEASE HELP 20 POINTS!!

Answers

Answer:

Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.

Step-by-step explanation:

Given that Ron paid X dollars for a pair of jeans, and Tim bought the same pair of jeans for half the price as Ron, if they paid a total of $ 45 for the 2 pairs, to determine how much did each spend on their jeans you must perform the following calculation:

X + 1 / 2X = 45

1X + 0.5X = 45

1.5X = 45

X = 45 / 1.5

X = 30

So Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.

Consider two consecutive odd positive integers. If their product is 23 more than their sum, what
are the two integers?

Answers

Answer:

Find two consecutive odd integers whose product is 23 more than their sum. Let x & x+2 be the 2 integers.

Step-by-step explanation:

The value of two consecutive odd positive integers are 5 and 6.

What are Integers?

A whole that can be positive , negative and zero is called integers.

Given that;

The product of two integers is 23 more that their sum.

Let two consecutive odd positive integers are x and x + 2.

Now, By the given condition we can formulate;

x (x + 2) = 23 + x + (x + 2)

x² + 2x = 23 + 2x + 2

x² + 2x = 25 + 2x

x² = 25

Take square root;

x = √25

x = ± 5

Since, Numbers are positive.

So, x = 5

And x + 1 = 5 + 1 = 6

Thus, The value of two consecutive odd positive integers are 5 and 6.

They emailed classmates, explaining the situation and suggesting that everyone wear pink the next day. They also bought fifty pink shirts to distribute at school. When the boy who had been threatened arrived for his second day of high school, he was met by hundreds of his fellow students wearing pink. The action served as a clear anti-bullying message.
