Simplify the ratio 5m:240cm

Mathematics
2 answers:
omeli [17]2 years ago

Answer:

To simplify the ratio make sure that the units are the same

5m:240cm

Change the meters into centimeters

That's

1m = 100cm

5m = 500cm

So we have

500cm:240cm

500/240

= 25/12

= 25:12

Hope this helps

Answer:

25:12

Step-by-step explanation:

First you have to convert both amounts into the same unit. So;

<em>5m × 100 = 500 cm </em>

We're multiplying by 100 because a metre is 100 times bigger than 1 cm.

This changes the ratio from 5:240 to 500:240, which makes it easier to get to your end result.

Now, find the Highest Common Factor of both 500 and 240 - much like you do when simplifying fractions.

Factors of 240 = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, <u>20</u>, 24, 30, 40, 48, 60, 80, 120 and 240.

Factors of 500 = 1, 2, 4, 5, 10, <u>20</u>, 25, 50, 100, 125, 250 and 500.

We then <u>divide both numbers by the HCF</u>, which we've just figured out is 20;

240 ÷ 20 = 12

500 ÷ 20 = 25

<h2>And there's your answer, <u>25:12</u></h2>

Point D is rotated 180 degrees using B as the center. Explain why the image of D must lie on the ray BA.
Igoryamba

Answer:

The image of D must lie on the ray BA, since ray BA is antiparallel to ray BD. That is, the angle between both rays is 180 degrees.

Step-by-step explanation:

Let be D' the image of D such that D is rotated 180 degrees counterclockwise with B as center of rotation.

D' must lie on the ray BA, since ray BA is antiparallel to ray BD. That is, the angle between both rays is 180 degrees.

olivia has $180 to buy presents for her 3 sisters and 2 nephews. She wants to spend $15 more on each sister than she spends on e
koban [17]
So
if x is the number she spent on each sister and y is the number she spent on each nephew then
180=3x+2y

she wants to spend 15 dollars more on sisters than nephews
so
x=15+y
solve

we have
180=3x+2y and
x=15+y
subsitute 15+y for x

180=3(15+y)+2y
180=45+3y+2y
180=45+5y
minus 45 both sides
135=5y
divide both sides by 5
27=y

solve for x
x=15+y
x=15+27
x=42

she spent $42 on each sister
