A certain building has a triangular shaped face to link up of the sides of the triangular base or 145 feet 257 feet in 290 feet five find the area of the base of the building

Answers

Answer 1

Answer:

18617.66 ft^2

Step-by-step explanation:

sides of triangular base

a=  145ft  ,

b = 257ft ,

c =  290ft

calculate the area of the base  

The base is a scalene triangle hence the area is calculated as follows

s = ( a + b + c ) / 2

  = ( 145 + 257 + 290 ) / 2 = 346

Area of triangle = [tex]\sqrt{s(s-a)(s-b)(s-c)} = \sqrt{346(201)(89)(56)}[/tex]

                          = 18617.66 ft^2

Answer:

11.90

Step-by-step explanation:

oh yes sorry I didn't see what you chose lol

Answer:

Yes

Step-by-step explanation:

Rounding two decimal points mean there will be two numbers behind the decimal and since 6 is more than 5 and influences the result of the 9 the answer would be 11.90. It could be 11.9 but having said there is two decimal places there should be a 0 hope this helps!!

find the slope-intercept equation of the line that passes through (0,1) and has a slope of -2/3

Answers

Answer:

y = -2/3x + 1

Step-by-step explanation:

We already know the slope, so all we need to do is find the y-intercept. To find that, we need to plug the coordinates into the equation so far, which is,

y = -2/3x + b

1 = -2/3(0) + b

1 = 0 +b

1 = b

So the equation is y = -2/3x + 1

HELP ASAPPPPP PLZZZZ Question in pic!!!!!

Answers

Step-by-step explanation:

Given

5y + 68 = 3y + 96 (vertically opposite angles) and

3x + 18 = 5x + 2 (vertically opposite angles)

Now solve for x.

[tex]3x + 18 = 5x + 2 \\ 3x + 18 - 5x = 2 \\ - 2x + 18 = 2 \\ - 2x = 2 - 18 \\ - 2x = - 16 \\ x = - 16 \div - 2 \\ = 8[/tex]

Now Solve for y.

[tex]5y + 68 = 3y + 96 \\ 5y + 68 - 3y = 96 \\ 2y + 68 = 96 \\ 2y = 96 - 68 \\ 2y = 28 \\ y = 14[/tex]
