Your answer to the question is: 3(2¼)=x
Answer:
-0.6 cm/min
Step-by-step explanation:
The formula for the area of a triangle is ...
A = (1/2)bh
Solving for the base, we find ...
b = 2A/h
Then the rate of change of the base is ...
b' = 2(A'h -Ah')/h^2
Filling in the given values, we find the rate of change of the base to be ...
b' = 2((2 cm^2/min)(20 cm) -(160 cm^2)(1 cm/min))/(20 cm)^2
= 2(40-160)/400 cm/min
= -0.6 cm/min
The base is decreasing at 0.6 cm/minute.

Answer: 63/100 and 0.63
Step-by-step explanation: To find the fraction and decimal that is represented by this model, we first need to count how many cubes are shaded in. In the diagram shown, 63 of the cubes are shaded in and there is 100 of the cubes in total. the fraction 63/100 cannot be reduced so that is our answer. Now, let's turn 63/100 into a decimal. To write 63/100 as a decimal, remember that the bar that separates the numerator and denominator of the fraction is a division bar in disguise. This means that we can divided 63 by 100 and we will get 0.63 which is the equivalent decimal.
Yes, of course.
Interior angles at each side are supplementary, so a trapezoid together with its rotation 180° makes a parallelogram. A parallelogram can always be used for tesselation.
