Answer:

I think it is 10 is the answer

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:

X =  12

Step-by-step explanation:

25 + 114 = 139

180 - 139 = 41

41 + 19 = 60

60 / 5 = 12

There's no 12p in the simplification

[tex](2p+3)^{2} =(2p)^{2} +3^{2} = 4p^{2} +9[/tex]

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:

[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:

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].

Answer:

370

Step-by-step explanation:

Round each answer into easier to add numbers. 92 and 91 round down to 90. 9 rounds up to 10.

Answer:

aprox 280

Step-by-step explanation:

if you need to add these numbers quickly you can estimate either with an overestimation or under estimation:

for an over estimation, you can find the nearest 10 or 100 that each value is so for this you have 92 + 91 +92 +9 which is close to 100 +100+100+10

so using this you can quickly guess that it would be somewhere around 310

for an under estimation you can do the same thing but rounding down so we instead would add 90 + 90 + 90 + 10 which gives 280

now using both we know the answer would be somewhere between 280 and 310

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:

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:

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:

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:

71°

Step-by-step explanation:

Line AB is parallel to line CD and that makes the angle given as 109 and the co-interior angle supplementary

since the sum of supplementary angles is equal to 180° :

180 - 109 = 71 is the measure of the co-interior angle

Answer:

V = 147 cm^3

Step-by-step explanation:

cut the shape into two boxes, one with dimensions of 13 x 3 x 5 and one with 2 x 5 x 3. Then solve for V for both then add.

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:

  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.

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.
