Answer:
473 yd^3
Step-by-step explanation:
The surface area of the square base is (11 yd)^2, or 121 yd^2.
The surface area of one of the slanting sides of the pyramid is
A = (1/2)(b)(h), which comes to A = (1/2)(11 yd)(16 yd) = 88 yd^2.
Thus, four such sides have a combined surface area of 352 yd^2.
Combining the surface areas of the slanting sides with the base area yields 473 yd^3
Answer:
24
Step-by-step explanation:
24 I think I don't remember
A. First, divide 1675 by 100 to find 1% of it.
1675 / 100 = 16.75
Then, multiply 16.75 by 4.6 to get 4.6%.
16.75 x 4.6 = 77.05
77.05 is the interest for one year.
Multiply it by 4 to get the interest for 4 years.
77.05 x 4 = 308.20
The interest earned is $308.20.
B. Add the interest to the original balance to get the total.
308.20 + 1675 = 1983.20
The balance of the account is $1983.20 after 4 years.
Hope this help!
The Answer is 0.15, you count all the decimal points places and move that amount.
