Answer:

the answer is A.  2370 sq. in

Step-by-step explanation:

area of the triangles first

A = 1/2 ad

a = (45 in) (20 in)

a = 1/2 (900 sq in)

a = 450 sq in

***remember to multiply 450 * 2 because you have 2 triangles***

Total area of both triangles is 900 sq. in.

Find the area of the 3 rectangles A = LW

1st rectangle and 2nd rectangle

a = cb

a = (30 in) (14 in)

a = 420 sq in. (make sure you add this again in the Total Surface area)

3rd rectangle

a = ab

a = (45 in) (14 in)

a = 630 sq. in

Total Surface area = 2 (1/2 ad) + 2(cb) + (ab)

= 2 (450 sq. in) + 2 (420 sq. in) + 630 sq. in

= 900 sq. in + 840 sq. in + 630 sq. in

= 2370 sq. in

9/4 plus 2/3 in fraction form please!
nasty-shy [4]

Answer:

The answer would be 35/12 or 2 and 3/4

Step-by-step explanation:

First we need to convert the fractions, so that they have the same denominator. A common denominator is 12. So, we mulitply 4 by 3 (because 4 X 3 = 12) and we do the same thing for 9. This makes the fraction 27/12. Now we mulitply 2/3 by 4 (because 3 X 4 = 12) and we also multiply 4 by 2 which gives us 8/12. Add 27/12 + 8/12 and you get 35/12 which can be simplified to 2 and 3/4.

On a number line the directed line segment from Q to S has endpoints Q at -14 and S at 2. Point R partitions the directed line s
liq [111]

Answer:

Step-by-step explanation:

The distance from Q to S is 2 - (-14), or 16.

We start at point Q.  Note how 3 and 5 add  up to 8, which allows us to write:

R = Q + (3/8)(16), or R = -14 + 6, or R = -8.

From R to S it is (5/8)(16), or 10 units.

The directed line segment is partitioned into segments of lengths 6 and 10, whose combined length is 16, as expected.
