the ratio the ratio of two numbers is 5:6 . find the sum of two numbers is 55. find the number​

Answer:

1. The answer is 3 students

2. 3.8, or rounded, 3.5

3. 4 batches of brownies

4. 16/9, 1.80, or 1.78

Step-by-step explanation:

1. If you divide 1/4 by 15, that would equal 3.75. Since you can't have partial of a person XD you should round it back to 3.

2. If you divide 1/5 by 19, that would be 3.8.

3. If you divide 2/3 by 6, that would be 4.

4. 1/9 divided by 16 would be 16/9. As a decimal, it would be 1.777778. Rounded, it would be 1.80, or 1.78.

Hope this helps you!

Answer:

y=1/2x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(0-(-4))/(6-(-2))

m=(0+4)/(6+2)

m=4/8=1/2

y-y1=m(x-x1)

y-(-4)=1/2(x-(-2))

y+4=1/2(x+2)

y=1/2x+2/2-4

y=1/2x+1-4

y=1/2x-3

Step-by-step explanation:

The pair of both decimals that represent rational numbers is in option [tex](a)[/tex].

A rational number is a number which is expressed as the ratio of two integers, where as the denominator should not be equal to zero [tex](\neq 0)[/tex] and   are terminating and no-terminating but repeating decimals.

Irrational numbers can not be expressed in the form of fractions and are non-terminating and non-recurring.

We have,

[tex]0.752[/tex] and [tex]0.232323.....[/tex]

In the above given numbers [tex]0.752[/tex] is terminating, so it is a rational number.

And,

[tex]0.232323....[/tex] is non-terminating and repeating number, so it is also a rational number.

So, the pair of option [tex](a)[/tex] i.e. [tex]0.752[/tex] and [tex]0.232323.....[/tex] is the pair of rational number.

Hence, we can say that the pair of both decimals that represent rational numbers is in option [tex](a)[/tex].

Answer:

[tex]log_3(\frac{7}{16}) =-0.753[/tex]

Step-by-step explanation:

Use the laws of log()

[tex]log_x(\frac{a}{b}) =log_x(a)-log_x(b)[/tex]

[tex]log_3(\frac{7}{16}) =log_3(7)-log_3(16)[/tex]

[tex]log_3(\frac{7}{16}) =log_3(7)-log_3(4^2)[/tex]  you can move exponent outside of log()

[tex]log_3(\frac{7}{16}) =log_3(7)-2log_3(4)[/tex]  

[tex]log_3(\frac{7}{16}) =(1.771)-2(1.262)[/tex]

[tex]log_3(\frac{7}{16}) =-0.753[/tex]

The required value of log₃ (7/16) is 0.753 which is determined by properties of logarithms.

There are four basic properties of logarithms:

logₐ(xy) = logₐx + logₐy.

logₐ(x/y) = logₐx - logₐy.

logₐ(xⁿ) = n logₐx.

logₐx = logₓa / logₓb.

The functions of logarithmic are given in the question

log₃ 4 = 1.262 and log₃ 7 = 1.771

We have to determine the value of log₃ (7/16)

⇒ log₃ (7/16) = log₃ 7 - log₃ 16

⇒ log₃ (7/16) = log₃ 7 - log₃ 4²

Using property of logarithm logₐ(xⁿ) = n logₐx.

⇒ log₃ (7/16) = log₃ 7 - 2 log₃ 4

Substitute the values of log₃ 4 = 1.262 and log₃ 7 = 1.771 in the above equation,

⇒ log₃ (7/16) = 1.771 - 2(1.262)

⇒ log₃ (7/16) = 1.771 - 2.524

⇒ log₃ (7/16) = 0.753

Therefore, the required value of log₃ (7/16) is 0.753.

Answer:

24

Step-by-step explanation:

Sally visited 16 stores when shopping for 2 hours.

Since Sally could look in 6 stores in 45 minutes. Hence:

Time spent in each store = 45 minutes/6 stores = 7.5 minutes per store.

Given a time of 2 hours = 2 hours * 60 minutes per hour = 120 minutes

Number of stores visited in 2 hours = 120 minute / 7.5 minute per store = 16 stores

Therefore Sally visited 16 stores in 2 hours.

Answer:

D) 3 1/8, 8 1/5, 8 1/3

Step-by-step explanation:

The order of the puppies' weights from least to greatest is the following:

[tex]3\frac{1}{8} , 8\frac{1}{5}, 8\frac{1}{3}[/tex]

Three wholes are less than eight wholes, which means that the puppy named Kenadi weighs the least.

Scout and Major weigh a bit more than eight pounds. However, Major weighs less than Scout because one fifth is less than one third.

[tex]8\frac{1}{5} < 8\frac{1}{3}[/tex]

This is why the correct option is D.
