Answer:
x = 31
Step-by-step explanation:
For the sum of the saved amounts to be 286, we must have ...
(5x +4) +(4x +3) = 286
9x = 279 . . . . . . . . . . . . . subtract 7
x = 31 . . . . . . . . . . . . divide by 9
The value of x would be 31.
G^9 is what I got. Hope this helps
Answer:
57pi
Step-by-step explanation:
First, let's get the area of the entire circle, including the shaded region:
pi*(8+3)^2 = 121pi
Next, let's get the area of the unshaded circle
pi*8^2 = 64pi
If we subtract the inner circle from the full circle, we get the shaded region:
121pi-64pi =
57pi
Answer:
Step-by-step explanation:
Let x be the random variable that represents the data speed.
Given, Confidence interval for population mean : (13.046, 22.15)
Let be the sample mean.
We need to write the confidence interval in "less than" format.
less than sign → <
Confidence interval in "less than" format will be:
The inner diameter of the washer is 7/10 inch, this value is gotten by multiplying the path by 2 and subtracting the result from the outer diameter
<h3>Mensuration of Shapes</h3>
Given Data
- Path Distance = 3/20 inch
The inner diameter
= Outer Diameter - 2*Path Distance
= 1 - 2*3/20
= 1- 6/20
= 1- 3/10
= 1/1 - 3/10
Find the LCM we have 10
= 10-3/10
= 7/10 inch
