X=c/1/a+1/b
Because you have to multiply both sides by x then regroup them, then you divide both sides by 1/a+1/b
Answer:
16.4 miles
Step-by-step explanation:
In this scenario, we are provided with the total distance of the race which Ben's dad ran as well as the fraction of that distance that Ben ran from his goal. In order to calculate the distance in miles that Ben ran we simply need to first multiply the total distance of the race by the fraction that is Ben's goal. We can simplify this even more by dividing the fraction and turning it into decimal form
3 / 4 = 0.75
0.75 * 26.2miles = 19.65miles
Now we can see that Ben's goal was to run 19.65miles but he was only able to run 5/6 of that. Therefore we can multiply this fraction by his goal to get the actual distance that he ran.
5 / 6 = 0.8333
0.8333 * 19.65 = 16.375
Finally, we can see that Ben ran a total of 16.4 miles (rounded to the nearest tenth)
Answer:
You can't add those two matrices as they do not have the same dimensions
Step-by-step explanation:
This also relates to subtraction as well (you need to have same dimensions)
Field area:
280 x 390 = 109,200 m²
Barn area:
25 x 33 = 825 m²
let area: 109,200 - 825 = 108,375 m²
Answer:
The diameter is 14
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know the area is 49 pi
49 pi = pi r^2
Divide each side by pi
49 pi/ pi = pi r^2/pi
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 =r
We want the diameter
d = 2r
d = 2*7
d = 14
