Alexa is saving to buy a new bike that costs $265. So far she has saved $45. If she is able to save $11 each week, how many weeks will it take her to save enough to buy her coveted bike?
Kole wrote (265 - 45)/11 = w.
Bella wrote 11w + 45 = 265.
Who do you agree with? Justify your response.

Answers

Answer:

nose

Step-by-step explanation:

They are both correct to an extent; however, Kole is more correct in the fact that he simplified the equation. Where Bella has the right idea but did not simplify the equation.

I agree with Kole because 220/11 =20 weeks until she has saved enough for her bike.

Both equations get you the correct answer though:

Kole: 265-45=220/11=20 weeks

Bella: 11w + 45 = 265 ... subtract 45 from both sides ... 11w = 220 ... divide both sides by 11 and you get 20 weeks

Answer:

8 : 20 and 24 : 60

Step-by-step explanation:

Given the ratio

[tex]\frac{2}{5}[/tex]

To obtain a ratio with 20 on the denominator multiply numerator and denominator by 4

= [tex]\frac{2(4)}{5(4)}[/tex] = [tex]\frac{8}{20}[/tex]

To obtain a ratio with 24 on the numerator multiply numerator and denominator by 12

= [tex]\frac{2(12)}{5(12)}[/tex] = [tex]\frac{24}{60}[/tex]

Use formula for cube volume:

V=a³

Then add informations you already have and you are done.

V=0,5³

V=0,125 m³

Answer:

0.125

Step-by-step explanation:

The formula to find the volume of a cube is: V=a^3

Since we are given that one side of the cube is 0.5 m, you can take 0.5 and insert it into the formula V=a^3

V=0.5^3

V=0.125

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s eyes to be 1 times as far apart as Dan’s eyes. A scale giant would have the same multiple for both.

If Dan's eyes are 5 cm apart, how many centimeters apart should Marcellus's eyes be?

Answers

If you dragged Marcellus’s eyes apart 1x farther than Dan’s eyes then they would both have eyes that are 5cm apart because 5 x 1 = 5

Marcellus's eyes should be 5 cm apart

If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;

Marcellus eyes are 1x far apart as Dan's eyes.

If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.

Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.

Essentially, Marcellus's eyes will be just as wide as Dan's eyes
