Answer:

10x+17y = z

Step-by-step explanation:

You have to multiple 10 by the number of t shirts you have(x)

Then you have to multiply 17 by the number of long sleeve shirts you have (y)

You then have to add 10x and 17y to get your total cost(z)

The cup was filled at a constant rate. It started empty. After 2 seconds, it held 70 cm cubed of water.Find the percent of the c

Helen [10]

Answer:

In 3 seconds the cup is filled with $105\ cm^3$ <u>.</u>

Step-by-step explanation:

Given:

2 seconds = $70\ cm^3$ water

We need to find the percent of the cup that is filled with water after 3 seconds.

Solution:

Now Given:

The cup was filled at a constant rate.

First we will find the volume of water filled in the cup after 1 seconds.

2 seconds = $70\ cm^3$ water

1 seconds = Volume of water filled in 1 second.

By Using Unitary method we get;

Volume of water filled in 1 second = $\frac{70}{2}= 35\ cm^3$

Now we will find the volume of water filled in the cup after 3 seconds.

1 second = $35\ cm^3$ of water is filled

3 seconds = volume of water filled in the cup after 3 seconds

Again by using Unitary method we get;

volume of water filled in the cup after 3 seconds = $35 \times 3 = 105\ cm^3$

Hence In 3 seconds the cup is filled with $105\ cm^3$ .

To find the percent of the cup filled with water after 3 seconds we would required the dimensions of the cup which is not available in the question.

Solve each triangle - find any missing side and angle measures. Round answers to the nearest tenth.

Basile [38]

The sides of the right-angle triangle will be 16 units and 20.30 units. And the missing angle will be 52°.

<h3>What is a right-angle triangle?</h3>

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The side AC will be

tan 38° = 12.5 / AC

AC = 15.999

AC ≈ 16 units

Then the side AB will be

AB² = 12.5² + 16²

AB = 20.30 units

We know that the angle sum is 180 degrees. Then we have

∠A + ∠B + ∠C = 180°

38° + ∠B + 90° = 180°

∠B = 52°

More about the right-angle triangle link is given below.

Products of equal value totaling $480 are sold to an audience of an unknown amount of people. the entrance fee is $10 per person

Sholpan [36]

Y = $\frac{10x+480}{x}$

This is because the total cost is 10x + 480 and then that needs to be divided by the amount of people.
