Answer:

Drinks cost $10 and bag of popcorn $10.25

Step-by-step explanation:

In this case we can solve it using a 2x2 system of equations, like this:

let x: price of bag of popcorn

let y: price of drinks

So:

1 * x + 6 * y = 70.25 => x = 70.25 - 6 * y

5 * x + 12 * y = 171.25  

Replacing, we are left with that:

5 * (70.25 - 6 * y) + 12 * y = 171.25  

351.25 - 30 * y + 12 * y = 171.25

- 30 * y + 12 * y = 171.25 - 351.25

-18 * y = -180

y = 180/18

y = 10

Now to calculate x:

x = 70.25 - 6 * 10

x = 10.25

this means that the drinks cost $10 and bag of popcorn $10.25

Consider the triangle below. Determine the angle measure for the bottom two angles in order for the triangle to be classified as
FinnZ [79.3K]
Answer:

The angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle are 30 degrees each

Explanation:

An isosceles triangle has two of its angles equal.

Given that one angle is 120 degrees, assuming the remaining angles are equal, since the sum of the angles in a triangle is 180 degrees, we have:

120 + x + x = 180

120 + 2x = 180

2x = 180 - 120 = 60

x = 60/2 = 30

Each of the remaining angles measure 30 degrees

ALGEBRA ONE!!!!!1 34 POINTS I WILLLLL GIVE TOOOO YOUUUUU!!
Marina86 [1]

Answer:

±sqrt(T*L/m)=v

Step-by-step explanation:

T=mv^2/L

We want to solve the equation for v

Multiply each side by L

T*L=mv^2/L *L

T*L=mv^2

Divide each side by m

TL/m=mv^2/m

T*L/m=v^2

Take the square root of each side

±sqrt(T*L/m)=sqrt(v^2)

±sqrt(T*L/m)=v

Find the volume of the sphere. Round your answer to the nearest tenth.
dusya [7]

Answer:

Step-by-step explanation:

Remark

All you need do is find the radius and put it into the formula V = (4/3) pi r^3.

Givens

d = 12 yards

r = d/2

Solution

r = 12 yds/2 = 6 yds

V = 4/3 pi r^3

V = 4/3 * 3.14 * 6*6*6

V = 904.32

Answer 904.4 yd^3

<h2><u>Given</u> :</h2>

The given equations are :

\longrightarrow15b + 10g = 8640 \:  \:  \:  \:  \:   - (1)

\longrightarrow b + g = 708 \:  \:  \:  \:  \:  \:  - (2)

Let's solve for g in equation (2) :

\longrightarrow b + g = 708

\longrightarrow g = 708 - b \:  \:  \:  \:  \:  - (3)

now, let's plug value of g from equation (3) into equation (1) :

\longrightarrow15b + 10g = 8640

\longrightarrow15b + 10(708 - b) = 8640

\longrightarrow15b - 10b + 7080 = 8640

\longrightarrow5b = 1560

\longrightarrow b = 312

plugging value of b in equation (3) :

\longrightarrow g = 708 - b

\longrightarrow g = 708 - 312

\longrightarrow g =39 6

since " g " represents ground seats, number of ground seats :

=》396

And " b " represents balcony seat, therefore it is equal to :

=》312
