Answer:

5:2 , 30:12 , 60:24 , etc.

Step-by-step explanation:

To identify ratios equivalent to 15:6, all you need to do is multiply or divide both numbers in the ratio by the same amount to find an equivalent ratio.

So, for example:

1:2 --> 1*2 : 2*2 = 2:4 Both one half, so equal.

Now for 15:6...

Let's divide by the least common denominator ( 3 )

15 / 3 and 6 / 3 = 5 and 2

So 15:6 = 5:2

And we can also multiply the ratio by any constant as well...

For example 15 * 2 and 6 * 2

So 30:12 = 15:6

Hope this helped!

Car rentals involve a $130 flat fee and an additional cost of $31.67 a day what is the maximum number of days you can rent a car
Dmitry_Shevchenko [17]
The equation is $130 + $31.67x = 500
Subtract 130 from both sides $31.67x = $370
Divide $31.67 from both sides
X=11.68
BUT
you can’t have .68 of a day so the answer is 11 days.

Brian has $100 in his pocket. As he is walking home 1/4th of the money falls out of his wallet. Of the remaining money, he uses
emmasim [6.3K]

Answer:

$40

Step-by-step explanation:

Brian starts at $100, then loses 1/4th of the money,

100/4 = 25,

then you subtract 25 from 100, which gives you 75

With the remaining $75, he spends $15 on girl scout cookies,

75 - 15 = 60

He then has $60 remaining, but while walking home, loses 1/3 of the total amount.

60/3 = 20,

you then subtract 20 from 60, which gives you 40

Therefore, $40 is what is remaining.

Can pls someone help me I need help
LiRa [457]

Answer:

180-degree angle

This is not a 90-degree angle because if it were to be, then it would be AB, which is not what we are going for, which leaves BC as 180 degrees (if you see it on a protractor)

Simplify 1/4-7i to get a complex number in standard a + bi form.
Romashka [77]

Answer:

\frac{1}{4-7i}=\frac{4}{65}+\frac{7}{65}i

Step-by-step explanation:

we are given

\frac{1}{4-7i}

Firstly, we will get rid of imaginary term from denominator

so, we will multiply conjugate to both top and bottom term

\frac{1}{4-7i}=\frac{1\times (4+7i)}{(4-7i)\times (4+7i)}

\frac{1}{4-7i}=\frac{4+7i}{4^2-(7i)^2}

\frac{1}{4-7i}=\frac{4+7i}{16+49}

\frac{1}{4-7i}=\frac{4+7i}{65}

we can also write as

so, we get

\frac{1}{4-7i}=\frac{4}{65}+\frac{7}{65}i
