Firstly it is important to make both the units same for creating a
ratio. Here one of the number mentioned is in centimeter while the other number that is mentioned is in millimeter.
We already know
1 cm = 10 mm
Then
120 cm = 10 * 120 mm
= 1200 mm
Now we can go for creating the required ratio.
So the ratio that compares 1200 mm to 80 mm is = 1200:80
= 120:8
= 15:1
So the correct ratio is 15 to 1. The correct option among all the options given in the question is option "C".
She will need 20 1/2 yards of fabric. 5*4= 20 and (1/8)*4=1/2.
Answer:
31
Step-by-step explanation:
PEMDAS is Parentheses, Exponent, Multiplication, Addition, Subtraction
This is just the order you do the operations.
First, Parentheses.
Second, Exponents,
Third, Multiplication or Division
Last, Addition or Subtraction
So we have,
[6(20) + 3(15)] ÷ 5
We first look at Parentheses.
The first case is 6(20)
6(20) = 120
We have [120 + 3(15)]÷ 5
We solve 3(15) as its the next parentheses
3(15) = 45
We have [120 + 45] ÷ 5
Then we solve for [120 + 45] as it's in brackets.
[165] ÷ 5 = 31
The answer is 31.
Answer:
-11.8
Step-by-step explanation:
<u>Given:</u>
-3.4 to 12.4 increased (difference = 15.8)
12.4 to 20.4 decreased (difference = 8)
20.4 to 3.2 increased (difference = 17.2)
<u>To find:</u>
Final temperature.
Solution:
As we noticed, this is a pattern of increase, decrease, increase... (and so on and so forth). From this alone, we have gotten the clue that the temperature is going to decrease. But here is the thing, How far will it decrease?
Use the difference of the starting result to find the ending result.
3.2 - 15
= -11.8
Therefore, the final temperature is -11.8.
Plug in the values of the ordered pairs into the equations.
41 = 5(8) + 1
41 = 40 + 1
41 = 41
So, A y = 5x + 1 is the answer.
