8.)What is the Measurement of angle 2?<br><br> 9.) What is the measure of angle 7?
EastWind [94]

Answer:

angle 2 = 90° {corresponding angles}

angle 7 + angle 5 = 180° {linear pair}

or, angle 7 + 100° = 180° {angle 5 is corresponding to 100°}

so, angle 7 = 80°

Which of these equations is for a line perpendicular to y-3=5(x-2)?
olasank [31]

Answer:

C

Step-by-step explanation:

y-3=5(x-2)  (rearrange this to be in slope- intercept from) (add 3 to both sides)

y = 5(x-2) + 3   (distribute parentheses)

y = x(5) - 2(5) + 3

y = 5x -10 + 3

y = 5x - 7

recall that for a line with gradient m, the gradient of the perpendicular line will be - (1/m)

hence in our case, our gradient of the original line is 5, hence the gradient of the perpendicular line is -1/5

From the choices, the only one that is consistent with this is C

i.e choice C:

5y + x = 25

5y = -x + 25

y = -(1/5) x + 5   ===> gradient of -1/5

A cone has a diameter of 24 in. and a slant height of 15 in. What is the approximate volume of the cone? Use 3.14 to approximate
g100num [7]
So you are using Volume...

V=1/3(pi)r^2h
as you go thu this equation

15 x 15 =225
12 x12= 144
225-144= 81
81/9=9

which your piece would be 1/3 pi r^2h answer is 1356.48
and you round it to the nearest tenth. So

 ( 1356.5) is ur answer...... So (B)
