Answer:
width = 11, len = 19
Step-by-step explanation:
length = 2w - 3
l = length
w = width
2(length) + 2(width) = perimeter
2(2w - 3) + 2(w) = 60
6w -6 =60
w = 11
len = 2(11) - 3
If you mix 1 liter of the 10% solution with 1 liter of the 30% solution, you will have 2 liters of 20% solution. Keeping that in mind, you must mix half of the number of liters with 10%, and the other half with 30% in order to get 20%. So knowing all those things, we can do the problem. She needs 15 liters of 20%, so you need to mix 7.5 liters of 10% with 7.5 liters of 30%. After mixing those, you'll have 15 liters of 20% solution. I hope this helps. Please put as brainliest.
Answer:
f(x)=x/7
Step-by-step explanation:
f(x)=7x
y=7x
x=7y (switch y and x for inverse)
x=7y (isolate y)
x/7=y
The inverse of f(x)=7x is f(x)=x/7
(s + 3)
There are 4 sides on a square.
Answer - 4( s + 3)
Hope this Helps!!
Answer:
(a) = 60
(b) = 70
Step-by-step explanation:
(a) Sum of all the angles of a triangle is 180
This is an equilateral Triangle
which means all the sides are equal since all the sides are equal that means all the angles are equal
(b) this is an isosceles triangle with two equal sides that means the two opposite angles are equal
