Answer:
This question is asking you to find the ending position of a shape (particle) that is moving horizontally along the horizontal axis by finding its velocity with the equation shown. When t=0, the shape is 4 units to the left of the vertical axis, so it wants you to find where on the horizontal axis the shape is when t = 8. Hope this helped!!!
You will need to use the Pythagorean Theorem and plug in the varibles. The rope is the hypotenuse of the right triangle formed, and the 40ft water is the vertical leg, which leaves the ocean floor to be the horizontal leg.[a^{2}+b^{2}=c^{2}\] \[a^{2}+40^{2}=140^{2}\] Then solve for a. \[a^{2}=18000\] \[a=134.164\]
The equation for the volume of a pyramid is (l*w*h)/3
since the problem gave you the base area, that would be the l *w
so now you would need to multiply the base area by the height, then divide by 3
16 * 15 = 240
240/ = 80 cubic centimeters
Answer:
base is 10 height is 5
Step-by-step explanation:
forgive me if I'm wrong but since the area of a triangle is base x height 1/2 and since the area is 25 I did 25 x 2 and got 50 as the area that was not divided by 1/2 and since 10 x 5 is 50 and 10 is twice the height of 5
Answer:
1.75 pounds costing 10.85 is better buy as it is cheaper at 6.2 per pound
Step-by-step explanation:
1.37 pounds cost 9.59
that is 1 pound = 9.59/1.37
= 7
for 1.75 pounds costing 10.85
1 pounds = 10.85/1.75
= 6.2
Therefore at this cost prices, 1.7 pounds costing 10.85 is better as it is cheaper
