For the first question, simply make a right angle triangle with the following dimensions.
The angle of elevation or the angle from the ground between the first floor and ground is 60 degrees.
The height between the 2 floors is 26 feet.
Solve for the hypotenuse, or the diagonal length between the first and second floors.
Then for the second question, divide the length in feet by the rate to find the time it takes for the object to move.
Given that the perimeter of rhombus ABCD is 20 cm, the length of the sides will be:
length=20/4=5 cm
the ratio of the diagonals is 4:3, hence suppose the common factor on the diagonals is x such that:
AC=4x and BD=3x
using Pythagorean theorem, the length of one side of the rhombus will be:
c^2=a^2+b^2
substituting our values we get:
5²=(2x)²+(1.5x)²
25=4x²+2.25x²
25=6.25x²
x²=4
x=2
hence the length of the diagonals will be:
AC=4x=4×2=8 cm
BD=3x=3×2=6 cm
Hence the area of the rhombus wll be:
Area=1/2(AC×BD)
=1/2×8×6
=24 cm²
Answer:
the answer is 10 percent off because that is 13 dollars
Step-by-step explanation:
if you do 130 times 10 it is 1300, then divide by 100 it equals 13 dollars off. if you did the other coupon it would only be 10 dollars off
Answer:
A. Rational number
Step-by-step explanation:
It is not a whole number or integer because it's a fraction. so it's the rational of a whole number.
