Mathematics

Answer:

13170 to the nearest whole number.

Step-by-step explanation:

We can use Heron's formula to do this:

Area =  √[s(s-a)(s-b)(s-c)]    where s = the semi-perimeter.

s =  (155+175+260)/ 2

= 295

Therefore the Area = √ 295(295-155)(295-175)(295-260)

= √173460000

=  13170.42.

Zanzabum

Answer:

y=0.75x+3.75

Step-by-step explanation:

The slope is

\frac{6 - 4.5}{3 - 1}  =   \frac{3}{4}

Substituting into point-slope form,

y - 6 = 0.75(x - 3)

y - 6 = 0.75x - 2.25

y = 0.75x + 3.75

What is x equal to ? Link down below.
scZoUnD [109]

Answer:

50

Step-by-step explanation:

Because of supplementary angles that line has to equal to 180

180-75 = 105

so 105 = (2x + 5)

you can subtract 5 from each side and get

100 = (2x)

then divide each side by 2 and you get

x = 50

you can check it by doing (2 x 50 + 5)

2 x 50 = 100 + 5 = 105 + 75 = 180

Maurinko [17]

Answer:

704 square yards

Step-by-step explanation:

10 * 19 = 190

190 * 2 = 380

12 * 19 = 228

12 / 2 = 6

6 * 8 = 48

48 * 2 = 96

96 + 228 + 380 = <em><u>704</u></em>
