Answer:
46.2 mi is the right answer.
Step-by-step explanation:
In this question we will follow the property of congruence of two triangles.
Here two triangles formed are triangle formed by Alba, Cray and Blare and a triangle formed by Service station, Cray and Blare.
The distance between Alba and Blare = 130 mi
The distance between Alba and Cray = 120 mi
As we know in the congruent triangles all sides are in the same ratio.
Now we apply the property of the theorem
![\frac{Distance(Alba-Cray)}{Distance(Alba-Blare)}= \frac{Distance(Cray-Service station)}{Distance(Cray-Blare)}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%28Alba-Cray%29%7D%7BDistance%28Alba-Blare%29%7D%3D%20%5Cfrac%7BDistance%28Cray-Service%20station%29%7D%7BDistance%28Cray-Blare%29%7D)
![\frac{120}{130}=\frac{x}{50}](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B130%7D%3D%5Cfrac%7Bx%7D%7B50%7D)
![x=50\frac{120}{130}](https://tex.z-dn.net/?f=x%3D50%5Cfrac%7B120%7D%7B130%7D)
x = 46.2 mi
Answer: Equation of st line is Y= -9X + 141
Step-by-step explanation: Given Y= 24 when X = 13 and Y = 87 when X = 6
Let the equation be Y = mX + C
24 = m*13 +C
and 87 = m* 6 +C
Give m = -9 and C = 141
Equation of st line is Y= -9X + 141
Here we are given how much work is done in a fix time interval
then they ask to find the rate of doing the work .
in such problem we can find the rate of doing a work by using the formula :
amount of work done
--------------------------------------------------- = work done in unit time
Time taken to do that amount of work
In 40 minutes number of pages she reads = 50
In 1 minutes number of pages she would be reading = 50 /40
= 5/4 page
Answer 5/4 page .
To avoid confusion, remember PEMDAS. This is the order of operation.
Parenthesis, Exponents, Multiply, Divide, Add, Subtract
21 ÷ 7 + 20 * 102 * 2 - 3
No parenthesis and no exponents, proceed to multiplication.
20 * 102 * 2 = 4,080
Then, perform division
21÷7 = 3
Then, do addition
3 + 4080 = 4083
Lastly, do subtraction
4,083 - 3 = 4,080
So, 21 ÷ 7 + 20 * 102 * 2 - 3 = 4,080
