Mathematics
1 answer:
MakcuM [25]4 years ago
4 0

Answer:

y = 9

Step-by-step explanation:

6y + 5 + 9y + 30 = 170

15y + 35 = 170

15y + 35 - 35 = 170 - 35

15y = 135

\frac{15y}{15} = \frac{135}{15}

y = 9

15(9) + 35 = 170

135 + 35 = 170

170 = 170

two right triangles are similar if an acute angle of one triangle is congruent to an acute angle of the other triangle. a. true
MArishka [77]
Answer:  True

One angle of a right triangle  = 90°
Let x =  the acute angle of one angle.
Let y =  the angle of the other angle.

Because the sum of angles in a triangle is 180°,
x + y + 90 = 180
x + y = 90
y = 90 - x

Therefore the angles for each of the two triangles are
x, 90° - x, 90°.

The two triangles are therefore similar because of AAA (Angle, Angle, Angle).

Disregarding wind resistance the distance a body falls from rest varies directly as th squares of the time it falls if a skydive
Firdavs [7]

Answer:

The skydiver will fall 1600 ft in 10 seconds.

Step-by-step explanation:

<u>Distance a body falls from rest varies directly as the squares of the time it falls </u>

Let distance = s    

      time = t

Therefore , s = k \times t^{2}

Given, the body falls 64 ft in 2 seconds.

Substituting in above equation,

64 = k \times (2)^{2}

64 = k \times (4)

 k  = \frac{64}{4}

 k = 16 ft/s^{2}

We have to find how much he will fall in 10 seconds.

s = k \times t^{2}

s = 16 \times 10^{2}

s = 16 \times 100

s = 1600 ft
