The average rate is (4%*2+8%)/3=16/3%=5-1/3%
Therefore the original investment was
3664/(16/300)=300*3664/16=68700,
of which 1/3 was at 8% = 22,900
and 2/3 was at 4% = 45,800
Check:45,800*.04+22,900*.08=3664 yay!
Because QRST is a rectangle, that means all of the angles must be a right angle, which are 90 degrees. Using this information, solve the expression by creating an equation that lets angle S = 90.
90 = 7x + 55
35 = 7x
x = 5
Step-by-step explanation:
Given that,
The depth of the pool is, h = 5 feet
Volume of the pool, V = 1200 cubic feet
We need to find the possible values for the dimensions of the pool. We know that the volume of a rectangle is given by :

Where
l and b are length and breadth
So,

The first possibillity for dimension is (10×24). Another can be (12×20).
To write an expression that shows 9 * 475 multiply using expanded form an distributive property we break 475 into three numbers
475 can be break into 400 + 70 + 5
Now we multiply by 9
9 x 475
9 x (400 + 70 + 5) (expanded form of 475)
We use distributive property here.
We distribute 9 inside the parenthesis
9 x 400 + 9 x 70 + 9 x 5
3600 + 630 + 45
4,275
