A bag contains 90 marbles, some red and some blue. If there are 60 blue marbles, what is the ratio of blue to red marbles?

Answers

Answer 1

Answer:

If there is a total of 90 marbles, and we know that there is 60 blue marbles. We can assume that the remaining 30 marbles are red therefore the ratio of red to red marbles would be 60÷30, which is 2. Or the ratio is 60:30 which is reduced to 2:1.

Mr.Williams' class built this platform for a school event. They also built a model of the platform in which 1 foot was represented by 2 inches. What is the volume of the platform? What is the volume of the model?

A right cylinder has a diameter of 50 mm and a height of 40 mm as shown. What Is the volume of the cylinder.A: 6280mm

B: 78,500 mm

C: 314,000 mm

D: 25,000 mm

Answers

Volume = 150796.4 mm^3

Volume of a cylinder is r^2*pi*h

radius is half of the diameter

so: 25^2 * 3.14 * 40

625 * 3.14 * 40 = 78500

78500 mm

Zeki's course at a trade school cost $1,500. The school gave him a loan for the full amount at an interest rate of 23%. The school expects a payment of $123.00 every month for 15 months. How much interest will Zeki have paid when the loan balance is $0?

Answers

Typically, interest is charged by month and since this problem doesn't say anything about compound interest, we'll treat it as simple. We can just simply multiply 1500 and 0.23 to get the total amount of interest. The total amount of interest is 345. Assuming that the $123 to be paid monthly doesn't include the interest yet, Zeki has to pay 345 in total. At the end of the 15 months, he would have paid 345.

Answer:

At the end he would have paid 345
