why do you multply by a power of 10 when writing a repeating decimal as a fraction

Answers

The goal is to multiply by a certain number (10, 100, 1000, etc.) so that when the original number is subtracted from the multiple, the repeating element cancels out. 10x = 2 is the result of multiplying by ten.

Point A is located at -0.75 and point B is located at 0.25 on a number line. Which expression shows how to find the distance between points A and B?

A. |–0.75| – 0.25

B. |–0.75 + 0.25|

C. |–0.75 – 0.25|

D. |0.75 – 0.25|













Answers

Answer:

Should be C sorry if not

Step-by-step explanation:

When I do the math in my head I take the distance between 0.75 and 0 and the distance between 0.25 and 0 and add them together giving me the distance between the two points. To get that distance you would subtract the two numbers from each other with the absolute value brackets on the outside of the equation so it will not make the negative a positive. If the negative is a positive, it would make it 0.50 which would be incorrect. The distance between the two points here would be 1.0 if that was the equation. That is a way I used to figure out equations like this when I was younger. Take it for what it is worth.

7/8 _ 1 which is larger ?

Answers

Answer:

[tex]1 \\ because \frac{7}{8} = .875 \\ thnk \: you[/tex]

Answer:

1 is larger

Step-by-step explanation:

It is helpful to recall what a fraction means. The denominator is the number of parts that you divide the units by. The numerator is the number of parts you take.

Divide 1 into 8 equal parts. Each part is 1/8. Now take 7 of those parts. You took 7/8. Since there are 8 parts in 1 and you only took 7 of them, you took less than 1. 7/8 means 7 parts out of 8.

That means that 7/8 is less than 1.

7/8 < 1

1 is larger

130. Geometry The length of a rectangle is five meters more than twice the
width. Express the length of the rectangle in terms of the width.

Answers

Answer: l = 2w + 5

Step-by-step explanation:

The length is five meters more than something. Since the 5 meters more than (addition) comes first, you know it's not going to be in parentheses and is instead going to precede the next term. Right now, your equation should look like

l = 5 + ?

Now, we get to "twice the width." This is the second term, the ? in the previous equation. Two times the width can just be written as 2w, so that's how you're going to express it. In the end, your final equation just comes out to

l = 5 + 2w

i need some help

Answers

Answer:

-28.4

Step-by-step explanation:

Remove parentheses:

(6.2+2+6)(-5+| -18÷6| )

Simplify 6.2 +2 to 8.2

(8.2+2+6)(-5+| -18÷6|)

Simplify  8.2+6 to 14.2

14.2(−5+∣−18÷6| )

Divide −18÷6= -3

14.2(−5+∣−3∣)

Simplify ∣−3∣

you get: 14.2 x (-5+3)

Remove parentheses and simplify -5+3= -2 to get:

14.2 x -2

$18 less than the original price is $48.

HELP!!

Answers

Answer:

i believe itd be 66 dollars :D

hope this helps !!

Step-by-step explanation:

x - 18 = 48

add 48 and 18 and get the answer = $66

The given information is,

→ $18 less than the original price is $48.

Let the value of original price be x.

The equation will be,

→ x - $18 = $48

Let's find the required solution,

→ x - 18 = 48

→ x = 48 + 18

→ [x = 66]

Hence, the original price is $66.

A person standing 20 feet from a streetlight casts a shadow as shown. How many times taller is the streetlight than the person? Assume the triangles are similar.

Answers

Answer:

We have two similar triangles; triangle ABC and triangle DBE

We can work out the scale factor of the two triangles by checking the corresponding lines

We have line EB correspond to line CB

The scale factor is EB ÷ CB = 30 ÷ 10 = 3

Line EB is 3 times longer than line CB

So, line DE is 3 times longer than line AC

The street light is the line DE and the person standing is the line AC

So, the street light is 3 times taller than the person standing.

WILL MARK BRAINIEST
Zach and Ginny are building model cars. Ginny's car is 2 more than 3 times the length of Zach's car. The sum of the lengths of both cars is 30 inches. Write an equation to determine the lengths of Zach's and Ginny's cars.
3x + 2 = 30
x + 2 + 3x = 30
2x + 3 = 30
x + 2x + 3 = 30

Answers

Answer:

x + 2 + 3x = 30

Step-by-step explanation:

Both lengths are unknown, but Ginny's car length is described in terms of Zach's car length, so we choose a variable for Zach's car length.

Let x = Zach's car length.

Zach's car length is x.

"Ginny's car is 2 more than 3 times the length of Zach's car."

Ginny's car length is 2 + 3x.

Add the lengths:

x + 2 + 3x

"The sum of the lengths of both cars is 30 inches."

x + 2 + 3x = 30

Answer: x + 2 + 3x = 30

Answers

Answer:

7

Step-by-step explanation:

You've said that both triangle are equal.

This means, both are in proportion

Let the unknown side be x

4 : 5 : x = 36 : 45 : 63

Divide LHS by 9

4 : 5 : x = 4 : 5 : 7

Since you may see x and 7 are same. So, the missing side is 7.

Answer:

Step-by-step explanation:

[tex]\frac{AB}{PQ} = \frac{BC}{QR}[/tex]                      #1 Find same sides  

So, [tex]\frac{4}{36} =\frac{BC}{63}[/tex]                 #2 fill it in.

36BC= 252                 #3 Cross multiply.

[tex]\frac{36BC}{36}[/tex]= [tex]\frac{252}{36}[/tex]                      #4 Divide by 36

BC= 7                           #5 Here's your answer!

If you want to check, plug the sides in.

[tex]\frac{4}{36} =\frac{5}{45} =\frac{7}{36}[/tex]

[tex]\frac{1}{9} =\frac{1}{9} =\frac{1}{9}[/tex]

The siplified fractions should all equal the same number. If they do, the triangles are similar.
