If you invest 300 dollars in an account at 7.5 percent interest per year simple interest how much will you bave in the account at the beggining of the 11th year

keeping in mind that the interest is accumulated as time passes by, so "at the beginning of the 11th year", we're in the 11th year, just beginning, however, only 10 years have passed by, so after 10 years then.

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
