It is written as a division problem. When dividing exponents with the same base you subtract the exponents. in this class, 7-5=2. So now you write the new exponent:

$6 ^{2}$

Find the surface area of the rectangular prism. justify your answer 3ft, 2ft, 4ft

Gelneren [198K]

Answer: $SA=52\ ft^2$

Step-by-step explanation:

The surface area of a rectangular prism can be calculated with the following formula:

$SA = 2wl + 2lh + 2hw$

Where "l" is the length of the rectangular prism, "w" is the width and "h" is the height.

In this case you can say that the length, the width and the heigth of this rectangular prism, are the following:

$l=4\ ft\\\\w=2\ ft\\\\h=3\ ft$

Knowing these values, you can substitute them into the formula shown before:

$SA = 2wl + 2lh + 2hw\\\\SA = 2(2\ ft)(4\ ft) + 2(4\ ft)(3\ ft)+ 2(3\ ft)(2\ ft)$

Finally, you must evaluate in order to calculate the surface area of the rectangular prism.

You get that this is:

$SA=2(8\ ft^2)+2(12\ ft^2)+2(6\ ft^2)\\\\SA=16\ ft^2+24\ ft^2+12\ ft^2\\\\SA=52\ ft^2$

Two angles of a quadrilateral measure 200° and 50°. The other two angles are in a ratio of 4:7. What are the measures of those t

Andrews [41]

Answer:

all angles will be 200, 50 , 40 and 70 - hope this helped :)

Step-by-step explanation:

everything equals to 360 after added together

360 - 250 = 110

110 divided by 11 = 10

4:7 (x 10)

40:70

the other angels will be 40 and 70
