What is the slope of the line which passes through (4, 7) and (2, 3)? (5 points)
Basile [38]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 7)

m = \frac{7-3}{4-2} = \frac{4}{2} = 2

Almost done. I need help with this part
valentina_108 [34]

Answer:

\%Percent = 14.3\%

Step-by-step explanation:

Required

15 is what percentage of 105

To do this, simply divide 15 by 105 multiplied by 100%.

So, we have:

\%Percent = \frac{15}{105} * 100\%

\%Percent = \frac{15*100}{105}\%

\%Percent = \frac{1500}{105}\%

\%Percent = 14.3\% --- approximated

Answer:

For the triangle having the sides 122m, 120m and 22m :

s=

2

122+120+22

=132m

Area of triangle =

s(s−a)(s−b)(s−c)

=

132(132−122)(132−120)(132−22)

=

132×10×12×110

=1320m

2

For the triangle having the sides 22m, 24m and 26m :

s=

2

22+24+26

=36m

=

36(36−22)(36−24)(36−26)

=

36×14×12×10

=24

105

=24×10.25m

2

(approx.)=246m

2

There, the area of the shaded portion

=(1320−246)m

2

=1074 m
