Answer:
7 yards.
Step-by-step explanation:
We know that in the case of the rectangle, the area is equal to the length times the width, that is:
A = l * w
We know that the value of the area is 35 yd ^ 2 and the width is 5 yd, therefore what we must do is solve for the length, like this:
l = A / w
replacing:
l = 35/5
l = 7
therefore the length of the rectangle flower bed is 7 yards.
Answer:
use formula
(x,y) =[ (x1+x2)/2 ,(y1+y2/2)]
=[(-2-8)/2, (3-9)/2]
=(-10/2 ,-6/2)
=(-5,-3)
<span> if the wavelength of a wave is 2 meters that means that every 2 meters it does its wave thing once. given that it travels 50 meters in one second the wave will have to do its wave thing 25 times in that distance.</span>
To find the solution to the given expression, we simply isolate the unknown variable m and perform the necessary operations. The solution is as follows.
(3/5)*(2m-10) = (2/3)*m + 10
15*[(3/5)*(2m-10) = (2/3)*m + 10]
9(2m-10) = 10m + 150
18m-90 =10m + 150
18m - 10m = 150 + 90
8m = 240
m = 240/8
m = 30
First, we multiply the whole expression to the least common denominator (LCD) which is 15. Multiplication and division were then performed accordingly. The terms containing the variable m were transposed to the left side of the equation. Mathematical operations were then applied to get the final value of m which is equal to 30.
