2000 * .1 = 200 + 2000 = 2200 (First year)
2200 *.1 = 220 + 2200 = 2420 (second year )
2420* .1 = 242 + 2420 = 2662 (third year )
2662 * .1 = 266.2 + 2662 = 2928.2 (fourth year)
They spent $2928.2 on clothing for 4 years.
The lower limits are the smallest value of every class.
So for the ninth class its 85.
Answer:
6ft
Step-by-step explanation:
Volume of rectangular prism = l x w x h, where h is height. So, we have to work out the height of the first prism in the following way. 224 divided by ( 8 x 4), which gives 7. So, to find l in the second prism, we have to :
L x W x H = 210
L x 5 x 7 = 210
L x 35 = 210
L = 210 <em>divided</em> by 35 = 6
Answer:
4.0625
Step-by-step explanation:
Step-by-step explanation:
Look at the picture.
We connect two congruent trapezoids as in the picture.
We created a parallelogram with a base length of b₁ + b₂ and a height h equal to the height of the trapezoid.
The formula of an area of a parallelogram:
The area of the trapezoid is half of the parallelogram area.
Therefore we have the formula of an area of trapezoid:
Therefore we need to be added the bases of a trapezoid.
