Which always share the properties of parallel lines?

the intersection of a wall and ceiling
the front edges of horizontal shelves in a bookshelf
the hands of a clock
the top and side edge of a window

Answer:

D

Step-by-step explanation:

Ok so you just need to plug in the points

A. -100= 0.1(100)-99 (FALSE)

B. -100= -100-100 (FALSE)

C. -100= 100 (FALSE)

D. -100= -(100) (TRUE)

Why did I plug in the numbers? Because its (x,y) meaning 100=X and -100=Y. So just plug them in to know the correct answer.

Answer:

a. 26/27  b. 4/5  c. 3/8  d. 7/16  a. 4/9  b. 3/5  c. 7/24  d. 3/14

Step-by-step explanation:

To solve problems like these, first make a common denominator. Then add/subtract. Finally, simplify.

a. 4/9+14/27=12/27+14/27=26/27

b. 3/10+1/2=3/10+5/10=8/10=4/5

c. 1/10+11/40=4/40+11/40=15/40=3/8

d. 1/16+3/8=1/16+6/16=7/16

a. 7/9-1/3=7/9-3/9=4/9

b. 3/4-3/20=15/20-3/20=12/20=3/5

c. 11/24-1/6=11/24-4/24=7/24

d. 9/14-3/7=9/14-6/14=3/14

Please give me Brainliest because I worked very hard on these. I hope you understand the concept better now and happy mathing!

Answer:

Answer:

82.36

Step-by-step explanation:

284 x 0.29 = 82.36

Have an amazing day!

PLEASE RATE!

Answer:

Step-by-step explanation:

Alright, so the answer is $400. So we know that $284 is a discount on the whole price, 29% off. So 284 is 71% of the whole price, 100%-29%=71%. So then I just divided 284 by 71 and got 4. 284/71=4. Because I divided it by 71, $4 is 1% of the whole price, so I multiplied 4 by 100 and got $400 as the original price. You can just do this equation with any type of calculator, also please select my answer as the brainliest.✌

|a|=-a is a < 0

Answer:

First, find the area of the surface of the shed. Two walls will have an area of 14 x 8 and two walls will have an area of 18 x 10. We get the equation 2(14x8) + 2(10x8) =  224 + 160 = 384 square feet

Next, divide the square footage of the shed's surface by 250 to find how many gallons of paint are needed. 384/250 = 1.54 gallons of paint (rounded to the nearest hundredth)

For the triangle questions, remember that the area of a triangle is [tex]\frac{(base)(height)}{2}[/tex]

Step-by-step explanation:

mutiply 3 x 3=9 than divide by 2 that is equals

4,5, mutiply 4 x 3 that is equals to 12 and divide by 2 that is equals to 6, then you dont need to divide thst one because its not a triangle, mutiply 4 x 8 = 32 32 + 4,5 + 6 = 42,5.

Step-by-step explanation:

for some reason the equation at the top says 7(x+2) but both of the equations at the bottom say 7(x-2)... I'm just going to do 7(x-2)

Emmanuels Work:

7(x-2)=91

distribute the 7 by multiplying both x and -2 by it

7x-14=91

add 14 to both sides

7x=105

divide both sides by 7

x=15

Mauricio's Work:

7(x-2)=91

to get rid of the 7 multiplication, divide both sides by 7

x-2=13

add 2 to both sides

x=15

I only know the first one with the method Emmanuel is doing sorry ;(

at least there's a guide in this image

Answer:

the correct answer is 102.16

Step-by-step explanation:

2(2*3.4+2*8.2+3.4*8.2)=102.16

Answer:

To find this, you must find the total number of points Sara has scored already.  She has answered 10 multiple choice questions which are 4 points each.  This means that Sara has scored 40 points so far.

If Sara wants to score at least 70 points, she needs to score at least 30 more points.  To find how many open-ended questions she needs to answer, you need to divide the remaining number of points by the number of points an open-ended question is worth.  The number we get will be x.

30/5 = 6

This means Sara must complete at least 6 open-ended questions to score 70.  Now, all we have to do is figure out which inequality sign to use.  Since Sara wants to score more than 70 points, it should be the "greater than" sign.

Your answer is:  x>6  

Step-by-step explanation:

Answer:

P ÷ 35% = X

Step-by-step explanation:

Because P is the original answer, it needs to be divided by 35% because it 35% off, so it would equal X, the original item price discounted.

Hope this helps!

The correct equation in terms of p, the original price of an item, to show the sale price of an item before any sales tax is,

⇒ Sale price = p - 35% of p

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

A clothing store is having a sale.

And, All items are on sale for 35% off the original price.

Now,

Let the original price of items = p

Then, The sale price is,

Sale price = p - 35% of p

                = p - 35p/100

                = p - 7p/20

                = 13p/20

Thus, The correct equation in terms of p, the original price of an item, to show the sale price of an item before any sales tax is,

⇒ Sale price = p - 35% of p
