The truck is 171.2%. if you calculate the percentage of 160 and add them together, you will get 171.2
Answer:
120 liters of 60% alcohol solution is needed
Step-by-step explanation:
Let's assume
x liters of 60% alcohol solution is added
so, we get solution as
we are given
40 liters of a 20% alcohol solution is
so, total alcohol solution is
now, we can find total solutions
total solutions is
now, it is making 50% solution
so, we get
now, we can solve for x
So,
120 liters of 60% alcohol solution is needed
Answer:
x = 2 11/12
Step-by-step explanation:
Multiply the equation by 12. This eliminates fractions.
... 12 -12x -28 = 12x +27 -36x -8
Collect terms.
... -16 -12x = -24x +19
Add 24x+16
... 12x = 35
Divide by the coefficient of x
... x = 35/12 = 2 11/12
Answer
364 i think
Step-by-step explanation:
find the area of triangles + area of rectangles
area of triangles: b x h x 1/2
6 x 4 x 1/2
= 12
but two triangles, so . double it and then you get 24 for the two triangles areA
area of rectangles;
l x w
22 x 6
= 132
but two up and down rectangles, so double it = 264
now back rectangle:
l x w
22 x 4
= 88
Add it all up together and you have the surface area!
Surface Area - The area of the surface of the 3D object, NOT volume
pls mark brainliest unless someone else answered it or im wrong thank you! :D
