Answer:

A=189\ mm^2

Step-by-step explanation:

<u>Surface Areas </u>

Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.

Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is

\displaystyle A_t=2*\frac{b.h}{2}=b.h=(4.5)(6)=27 mm^2

The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus

A_f=b.h=(7.5)(9)=67.5 \ mm^2

The back left area is another rectangle of 4.5 mm by 9 mm

A_l=b.h=(4.5)(9)=40.5  \ mm^2

Finally, the back right area is a rectangle of 6 mm by 9 mm

A_r=b.h=(6)(9)=54 \ mm^2

Thus, the total surface area of the prism is

A=A_t+A_f+A_l+A_r=27+67.5+40.5+54=189\ mm^2

\boxed{A=189\ mm^2}

Answer:

(-10)²= -10 × -10 = 100

Step-by-step explanation:

When any number is squared whether it is positive or negative, the result will always be positive:

Anything squared means the number multiplied by itself:

So:

(-10)²= -10 × -10 = 100

b. The median age could rise because of the improvement in medical technology. Also more advertisement of healthier life styles, such as eating healthy could have increase the median age.

c. No because this just shows the increase in life span not the decrease in children.

Step-by-step explanation:

a. more people on average lived longer lives. (explanation)

b. self explanatory I guess, my answer pretty much explained it.

c. life span of US citizens does not effect the children population. I guess you could say people lived longer lives to have more children, so possibly the number of children could have increased.
