The ratio of the radii of two circles is 4:9. What is the ratio of their circumferences?

Answers

Answer 1

Answer:
It will be 4:9 as well.
Circumference = 2πr,
r1 : r2 = 4:9 so this means that 2πr1 : 2πr2 = 4:9, because 2π = constant

Answer 2

Answer: 4/9; ratio is still the same
20 charrrrrrrrrrrr

Write 15 cookies to 40 brownies as a ratio in simplest form.

Answers

The equation for this question to reach the ratio in its simplest form would be 15:40 15 divided by 5 = 340 divided by 5 = 8, 3 : 8

if we write the ratio 15 cookies to 40 cookies we will get the following ratio

15:40

to write in simplest form we have to find the highest common factor for both 15 and 40

the factors for both 15 and 40 are as follows

15 - 1,3,5,15

40 - 1,2,4,5,8,10,20,40

the highest common factor is 5

so we have to divide both ny 5 to get the simplest form

$(15)/(5):(40)/(5) = 3:8$

ratio in the simplest form is 3:8

RootIndex 3 x StartRoot 16 EndRoot Superscript 4

Answers

Answer:

Option A

Step-by-step explanation:

We want to find an expression that is equivalent to

${16}^{ (3)/(4)x }$

Recall that:

${a}^{ (m)/(n) } = \sqrt[n]{ {a}^(m) }$

We apply this property of exponents to rewrite our expression:

We set a=16, n=4 and m=3x

This implies that:

${16}^{ (3x)/(4) } = \sqrt[4]{ {16}^(3x) } = (\sqrt[4]{ {16} })^(3x)$

The first choice is correct.

How many minutes is it from 8:00am to 11:40am?

Answers

Answer:

220 minutes

Step-by-step explanation:

Find how many hours there are between the two times which is 3 hours then multiply 3 by 60 because there are 60 minutes in an hour

Since the time is 11:40 we also know 40 minutes have passed so add the two minutes

40+180=220
