2 values that add up to -40 and 6

Answer:

the answer for the first part is 260

the equation is n+8

Step-by-step explanation:

all you need to do is take the starting number witch is 13 then you add 8 and then take that number and add 8 so thats why the equation is n+8 n equaling the starting number and 8 equaling to the reoccurring number.

Answer:

C

Step-by-step explanation:

Since the laptop is on sale for 40% off, the discount is 40% of the regular price. Note that they are asking for the discount and not the discounted price.

Discount

= 40% ×$450

= ⅖ ×$450

= $180

Thus, option c is correct.

Answer:

[tex]y=-\frac{2}{3}x+4[/tex]

Step-by-step explanation:

First you divide every number in the equation by 3:

2x+3y=12

÷3    ÷3   ÷3

Rewrite equation:

[tex]y=-\frac{2}{3}x+4[/tex]

Hence the correct answer is [tex]y=-\frac{2}{3}x+4[/tex]

Answer:

  about 154 square feet

Step-by-step explanation:

The area of the pool is given by the formula for the area of a circle:

  A = πr²

  A = π(7 ft)² = 49π ft² ≈ 153.94 ft²

About 154 square feet of material will be needed to cover the top of the pool.

Additional comment

The circumference of the pool is 2πr, or 14π feet -- about 44 feet.

The equation that represents the value of the car is v = $5000(1.085)^x.

Appreciation means when the value of a car increases with the passage of time. The formula that can be used to represent appreciation is:

FV = P (1 + r)^n

Where:

V = 5000(1.085)^X

Answer:

5/3

Step-by-step explanation:

An improper fraction is a fraction, not in mixed form, where the numerator (top half) is greater than the denominator (bottom half). Since this fraction is 1 2/3, we already have 1 full and 2/3 full. So, since the 1 is full, it means that in fraction form it equals 3/3.

We can finally add the fractions. [tex]2/3+3/3=5/3[/tex].

ATypically this is something done for factoring. To do that, I use trail and error. Do you need to do it by a system of equations?

Answer:

48cm

Step-by-step explanation:

The perimeter of first shape is 36cm. There are 3 semi circle (curves).

Therefore,

3 curves of semicircle (arc length) = 36

1 curve of semicircle (arc length) = 36/3

= 12cm

In picture 2,

4 semicircles (They've mentioned that they used the same semicircle for the 2nd shape also)

So,

4×12 = 48cm

Step-by-step explanation:

Answer:

When f(x) is 0, then x is -1.8.

Step-by-step explanation:

To find this, you simply have to look for the place where the line crosses the x axis. This is where y (or f(x)) is equal to 0. Since this graph only crosses that axis at x = -1.8, that is the number we are looking for.

1/5=2/10=5/25

To get 2/10, since, in the denominators, to go from 5 to 10, you multiply 5 by 2, I multiplied 1 and 2 to get the answer.

For 5/25, to go from 1 to 5 you multiply 1 by 5, so you multiply 5 by 5, and that's 25, so the denominator for that fraction is 25.

Answer:

A. $209.53

Step-by-step explanation:

First, we have to take away 15% from the 850 dollar total so we can divide the remaining amount between the friends.

15% can also be written as the fraction 0.15

850 x 0.15 = 127.5

Now, we subtract the money they put away from the total amount.

850 - 127.5 = 722.5

So, the three friends have $722.50 to split between each other.

To figure out what amount everyone gets, we will first at together the total hours they worked.

17.25 + 18.25 + 14.5 = 50

Since the total hours is 50, we can divide the number of hours Shawn worked by 50 to find out what fraction of the total time he worked.

14 ÷ 50 = 0.29

0.29 is the same as the percentage 29%. This means Shawn worked for 29% of the total time out of his friends.

So, he gets 29% of the 722.50 dollars.

0.29 x 722.5 = 209.525

Round it up to 209.53

Shawn gets $209.53

Answer:

137.13km

Step-by-step explanation:

A right triangle is formed, where h + r = 2+ 4700= 4702 km is the hypotenuse, r = 4700km is one leg and d is the other leg. By Pythagorean theorem:

4702² = 4700² + d²

d² = 4702² - 4700²

d = √18,804

d = 137.13 km

Answer:

x =39°

the total interior angles of a triangle is 180°

let the unknown angle be x,

solve:

x + 39 + 102 = 180°

x = 180° -  39° - 102°

x = 39°

Therefore the unknown angle is 39°

Answer:

2(4b-1)

Step-by-step explanation:

1. You would have to distribute first. So basically you just multiply 4 · 2b which gives you 8b and then 4 · 2

Answer to first step: -10+8b+8

2. Add the numbers. It should be -10 + 8 which would give you -2

Answer to second step: -2 + 8b

3. Rearranging the terms. So, instead of doing -2 + 8b you would have to do 8b - 2

Answer to third step: 8b - 2

4. 2(4b - 1) Find what times what gives you 8 (not 1 times 8) and the same for -2

Answer:

(rectangular prism); opposite sides are equal

Area of bottom base;

3 feet x 3 feet = 9 feet,

Area of above base, (9 x 2) = 18

Area of front;

6 feet x 3 feet = 18 feet

Area of back, (18 x 2) = 36

Area of right side;

6 feet x 3 feet = 18 feet

Area of left side, (18 x 2) = 36

Find the sum of all the areas added;

18 + 36 + 36 = 90 square feet
