50 ! last questions for today so plz halp. and plz tell how you got the answer # 1: which statement best describes the area of triangle abc shown below? a triangle abc is shown on a grid. the vertex a is on ordered pair 4 and 5, vertex b is on ordered pair 6 and 2, and the vertex c is on ordered pair 2 and 2. it is twice the area of a square of side length 4 units. it is one-half the area of a square of side length 4 units. it is twice the area of a rectangle with sides 4 units × 3 units. it is one-half the area of a rectangle with sides 4 units × 3 units. #2: a solid is composed of squares and equilateral triangles. its net is shown below: a triangular prism and its net are shown. the net is three squares with side length 2 units. attached above and below the middle square are equal sized triangles. the area of each triangle is 1.5 square units. the surface area of the triangular prism is square units. (input whole number only.) #3: at the school carnival, the sixth graders are making directional arrows, as shown below. a polygon shaped like an arrow is shown. the total height of the arrow head and the arrow tail is 9 inches. the base of the arrow tail is 4 inches. the width of the arrow is 6 inches, and the height of the tail of the arrow is 5 inches. each arrow is to be painted red. how much area needs to be painted for 1 arrow? 26 square inches 29 square inches 32 square inches 44 square inches

44 sq inches, i am so not sure.

The answer is 32 square inches because you multiply 4*5=20

Then 6*2=12 then add 20+12+2

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
