Answer:

B

Step-by-step explanation:

3 + f = 14 \frac{2}{7} ← change to improper fraction

3 + f = \frac{100}{7} ( multiply through by 7 to clear the fraction )

21 + 7f = 100 ( subtract 21 from both sides )

7f = 79 ( divide both sides by 7 )

f = \frac{79}{7} = 11 \frac{2}{7} → B

Answer:

B. f=11\frac{2}{7}

Step-by-step explanation:

We have the equation 3 + f = 14 2/7

We need to get f alone, doing so is subtracting three from both sides:

3 + f = 14 2/7

-3     = -3

14 2/7 - 3 = [11 2/7]

Leaving us with f = 11 2/7

This is B.

O A PQR is reflected over the x-axis. What are the<br> coordinates of O'?
topjm [15]

Answer:

(8,-2)

Step-by-step explanation:

When reflecting something across the X axis the y axis coordinate is the one that will change to put the position further up or down.  In this case we are moving it down to the same amount below the axis that it is now above it.  That means that since it is currently 2 above the X axis it would then be 2 below the X axis making it at -2 so the coordinates would be (8,-2)

I hope this helps and please don't hesitate to ask if there is anything still unclear!

A cylindrical metal pipe has a diameter of 8.4 millimeters and a height of 10 millimeters. A hole cut out of the center has a di
zhannawk [14.2K]

To solve this problem, we simply use the equation of volume for hollow cylinders:

V = π h (R^2 – r^2)

where V is volume, h is height = 10, R is outer radius = 8.4/2 = 4.2, r is inner radius = 6/2 = 3

 

V = π (10) (4.2^2 – 3^2)

<span>V = 86.4π = 271.43 mm^3</span>

18. what Gives the missing value in 2/5 = x/30?
Korolek [52]
X is equal to 12
This is because 5 was multiplied and 6 making 30. So you have to multiply 2 and 6 making x 12. Hope that makes sense

Tems11 [23]
For June:
 Bike:
 (4) * (3 1/4) = 13 miles
 Swim:
 (4) * (2 1/2) = 10 miles
 Total:
 13 + 10 = 23 miles
 For July:
 Bike:
 (3) * (4 3/4) = 14.25 miles
 Swim:
 (3) * (3 1/2) = 10.5 miles
 Total:
 14.25 + 10.5 = 24.75 miles
 The difference between both months is:
 24.75 - 23 = 1.75 miles
 Answer:
 
the total distance Cameron bike and swim in July compared to the total distance he bike in swim in June was 1.75 miles greater
