Janet invested $10,000, part at 2% and part at 12%. if the total interest at the end of the year is $600, how much did she invested at 2%

Answers

Janet invested $6000 at 2 %.

Let x = amount invested at 2 %. Then 10 000 - x = amount invested at 12 %

interest at 2 % + interest at 12 % = 600

0.02x + 0.12(10 000 – x) = 600

0.02x + 1200 – 0.12x = 600

0.10x = 600

x = 600/0.10 = 6000

A pentagonal prism is cut by a plane perpendicular to the base. What is the shape of the cross section that is formed?a pentagon with one pair of equal sides
a trapezoid with one pair of parallel sides
a rectangle
a triangle
a hexagon

Answers

The correct answer is:

a rectangle

Explanation:

In a right pentagonal prism, the bases are pentagons and the lateral faces are rectangles.

If we take a cross-section perpendicular to the base, this same cross-section will be parallel to the lateral faces. This means it will be the same shape as the lateral faces, which is a rectangle.

Answer:

rectangle

To determine the appropriate landing speed of an airplane, the formula D = .1x 2 − 3x + 22 is used, where x is the initial landing speed in feet per second and D is the distance needed in feet. If the landing speed is too fast, the pilot may run out of runway; if the speed is too slow, the plane may stall. What is the appropriate landing speed if the runway is 800 feet long?
