Answer:
Time spend doing math home work is 0.6 hour
Time spend doing English home work is0.6 hour
Time spend doing history home work is 0.9 hour
Time spend doing social studies home work is 0.3 hour
Step-by-step explanation:
Ratio of time spend by Timothy while doing math, english, history, and social studies homework :2:2:3:1
Let the time spend doing math home work be 2x
Let the time spend doing English home work be 2x
Let the time spend doing history home work be 3x
Let the time spend doing social studies home work be 1x
Total time spend by timothy = 2.4 hours
x = 0.3 hours
Time spend doing math home work =2x = 2 × 0.3 hour = 0.6 hour
Time spend doing English home work =2x = 2 × 0.3 hour = 0.6 hour
Time spend doing history home work =3x = 3 × 0.3 hour = 0.9 hour
Time spend doing social studies home work =1x = 1 × 0.3 hour = 0.3 hour

Answer:
The new shape will be cone with a radius of 17 units, tilt height 24 and units of height k.
Step-by-step explanation:
The image related to the exercise is necessary, to be able to solve therefore the attached one.
We have the following information:
Perimeter of the triangle = 58 units
Hypotenuse = 24 units
We have that the other two sides are equal and have x units, therefore we have the following:
x + x + 24 = 58
2 * x = 58-24
2 * x = 34
x = 34/2
x = 17
Now the triangle rotates around line k , and then it will result in a cone, which is a three-dimensional shape.
Therefore, the new shape will be cone with a radius of 17 units, tilt height 24 and units of height k.
