How do you solve 39= 1 3/10b

Answers

Answer 1

Answer: $39=1(3)/(10)b\n----------------------\n1(3)/(10)=(1*10+3)/(10)=(13)/(10)\n----------------------\n(13)/(10)b=39\ \ \ \ |divide\ both\ sides\ by\ (13)/(10)=multiply\ boths\ sides\ by\ (10)/(13)\n\nb=39*(10)/(13)\n\nb=3*10\n\n\boxed{b=30}$

ABCD is a rectangle. Find the length of each diagonal. AC = 2(x – 3) BD = x + 5

Answers

Diagonals of rectangles are equal. AC = BD, so 2(x-3) = x+5. 2x - 6 = x+5. x = 11. Plug this into x+5 and you get 11 +5 = 16.

Workout gym has a sign up fee of $15 and charges $1per day for membership.Healthy gym has a sign up fee and charges a $2 daily fee. Which system represent the real world situation?

Answers

Answer:

Step-by-step explanation:

If Workout gym has a $15 sign up and $1 daily fee and healthy gym has $5 sign up and $2 daily fee;

15a + 1b = 0

5a + 2b = 0

Since the sign up fee is constant, then a = 1; 15 + b = 0 and 5 +2b = 0

If b = 10, which represents 10 visits in a month, it is then ideal to visit the Workout gym if you plan on making more than 10 times monthly. If you plan on visiting less than 10 times monthly, then the Healthy gym is the better option.

What is the ratio that is equivalent to 2:3

Answers

Ratio is the relationship between the number of same unit to verify the how bigger or smaller is a number to the another when we compare two quantities to each we write them in the form of the ration. For the equivalent ratio we can multiply or subtract a value at both numerator and the denominator.The equivalent ratio of the given number is 10/15.

Given-

We have to find out the equivalent ratio of the given ratio, which is 2:3.To get the value of ratio we need to know about the term "ratio".

What is the ratio?

Ratio is the relationship between the number of same unit to verify the how bigger or smaller is a number to the another when we compare two quantities to each we write them in the form of the ratio.For the equivalent ratio we can multiply or subtract a value at both numerator and the denominator.

Now to find out the equivalent ratio we can multiply or divide both the numerator and the denominator of the given ratio. The given ratio,

$=(2)/(3)$

Let r be the equivalent ratio of the given number. Multiply the given ratio with number 5 in both numerator and denominator.

$r=(2*5)/(3* 5)$

$r=(10)/(15)$

Hence the equivalent ratio of the given number is 10/15.

I, personally am not good at ratios but I will try my best:)

So.. it is asking for a ratio that is equivalent to 2:3, now there are many ways to write a ratio. One of it is a fraction. So this would be 2/3 in a fraction form. Now, multiply 2 and 3 by 2 and you will get 4:6. To prove that they are equivalent, 4 goes into 2 and 6 goes into 3!

I hope this helps:)

How do you turn a decimal into a fraction?

Answers

ok so remember
0.1=tenth=1/10
0.01=hundreth=1/100
0.001=thousantht=1/1000
and so on
you just count how many decimal places it is

example

0.3=3/10

0.04=4/1000

0.0343=343/10000

In order to turn a fraction into a decimal, you simply have to complete the fraction by dividing the numerator (the number on top of the fraction) by the denominator (the number on the bottom of the fraction).

For example, say we have the fraction $(1)/(5)$ . All we have to do to convert it into a decimal is divide 1 by 5.

1 / 5 = 0.2

So, the fraction $(1)/(5)$ written as a decimal would be 0.2.
Hope that helped! =)
