Answer:

BC = 15.01

Step-by-step explanation:

Angle A is given.

For angle A, BC is the opposite leg.

For angle A, AC is the adjacent leg.

The trig ratio that relates the opposite leg to the adjacent leg is the tangent.

In general, for angle X,

\tan X = \dfrac{opp}{adj}

In our problem,

\tan A = \dfrac{BC}{AC}

\tan 65^\circ = \dfrac{BC}{7}

BC = 7 \tan 65^\circ

BC = 15.01

PLEASE HELP ASAP!! I will give brainliest
Olin [163]

Answer:

Part A: Data summary is given in the table

Part B: out of the total 100 students, 15 students do not like either tennis or track

\frac{15}{100}  = 0.15

0.15 × \frac{100}{100} = 15%

Part C:

Total no. of students that dislike track = 60

Total no. of students that dislike tennis = 40

According to the survey results, more people dislike track.

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

4x+y=17
faltersainse [42]

Answer:

x=4

y=1

Step-by-step explanation:

4x=7y+9

4x+y=17

7y+9+y=17

8y=17-9

8y=8

y=1

so

4x=7*1+9

4x=16

x=16/4

x=4
