Answer:

D = 160 degrees,

Step-by-step explanation:

-920 degrees / 360 = 2 remainder -200.

-200 = 360 - 200

= 160 degrees.

For a Saturday matinee, adult tickets cost $8.50 and kids under 12 pay only $7.00. If 80 tickets are sold for a total

jolli1 [7]

Answer:

30 adult tickets,
50 kids tickets

Step-by-step explanation:

<u>Given</u>

Cost of adult ticket = $8.50
Cost of kids ticket = $7.00
Number of tickets = 80
Total cost = $605

Let the adult ticket be a and kids be k

<u>We got equations</u>

a + k = 80
8.5a + 7k = 605

<u>From the first equation we get</u>

k = 80 -a

<u>Substituting k in the second equation</u>

8.5a + 7(80 - a) = 605
8.5a - 7a + 560= 605
1.5a = 45
a = 45/1.5
a = 30

<u>Then finding k</u>

k = 80 - 30 = 50

a stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where s(t) = 4.9t^2 + 29.

Alenkinab [10]

Answer:

t = 9 s

Step-by-step explanation:

A stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where

$s(t) = -4.9t^2 + 29.4+132.3$

We need to find when the stone will hit the ground. It means when s(t) = 0. So,

$-4.9t^2 + 29.4t+132.3=0\\\\t=-3\ and\ t=9$

So, the stone will take 9 seconds to hit the ground. Hence, this is the required solution.

She decides to change the length of the top of the top of the trapezoid shaped garden from 32 to 24 ft. Which expression finds t

gulaghasi [49]

Answer:

<h3>The change in the scale factor is $\frac{3}{4}$ ft</h3>

Step-by-step explanation:

Given that Sienna planned a trapezoid-shaped garden.

And She decides to change the length of the top of the trapezoid-shaped garden from 32 ft to 24 ft.

Let Old length of the top be 32 ft

Let New length of the top be 24 ft

$Scale factor =\frac{New length}{old length}$

$Scale factor = \frac{24}{32}$

$=\frac{3}{4}$ ft

<h3>∴ the change in the scale factor is $\frac{3}{4}$ ft</h3>

50 points but please give a helpful answer <3

They are all (SAS)side angle side except for the bottom right one. This is because the question does not give the little ticks to show that one side is the same as the other. It is not good enough to assume they are congruent without proof.
