## Answers

**Answer 1**

**Answer:**

35

**Step-by-step explanation:**

There are 3 angles in a triangle

∠1 , ∠2 , ∠3

Of which

∠1 = ∠2

∠3 = 110

By angle sum property

∠1 + ∠2 + ∠3 = 180

∠1 + ∠2 = 180-110

∠1 + ∠2 = 70

∠1 = 70 ÷ 2

=35

∠1 = ∠2 = 35

Hence , 35+35+110 = 180

**Answer 2**

**Answer:**

35°, 35°, 110°

**Step-by-step explanation:**

the sum of the 3 angles in a triangle = 180°

let the equal angles be x , then

x + x + 110 = 180 , that is

2x + 110 = 180 ( subtract 110 from both sides )

2x = 70 ( divide both sides by 2 )

x = 35

the measure of each angle is 35° , 35° , 110°

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $2,596 was collected on the sale of 1,216 tickets. How many of each type of ticket were sold?

### Answers

**Step-by-step explanation:**

Suppose adult tickets are x ticket

Student tickets are 1216 - x ticket

x(5) + (1216 - x)(1) = 2596

5x + 1216 - x = 2596

4x = 2596 - 1216

4x = 1380

x = 345

Adult tickets have 345 tickets

and student tickets have 1216 - 345 = 871 tickets.

© Decrease 20g by 25%

g.

### Answers

**Answer:**

15g

**Step-by-step explanation:**

Method A: Calculate the percent first

If you decrease an amount by 25%, you end up with 75% of the amount.

75% of 20g = 0.75 × 20g = 15g

Method B: Calculate the decrease first

We start with 20g. To decrease 20g by 25%, we calculate 25% of 20g.

25% of 20g = 0.25 × 20g = 5g

The decrease amount is 5g.

Now we subtract 5g from 20g.

20g - 5g = 15g

What is the solution to the equation?

x^2=40

Will give brainliest if correct and explained!!

### Answers

**Answer: 2√10**

**Step-by-step explanation:**

A way we can find what x equals, is to find the opposite of what ever sign is on a side, in the equation x^2=40, the opposite of squaring is to find the square root of it.

It is important that what you do to one side, you do to the other.

So we have to square root both sides so we can get rid of the ^2 on x to get x =. This would look like √x^2 = √40

The square root of x^2 would revert back to just x

To find the square root of 40, its important to first see if its a perfect square. In this scenario, it isnt. Because it isnt, we have to find the closest perfect square that we can multiply to get 40, in this equation, the closest would be 4 so we do 4*10.

Then we reduce the 4 by square root and we get 2

Then we cant do anything else with the 10, so we would right the answer as a radical, with the square root you got from the perfect square on the outside and the remainder on the inside of the square root, like x√r where x is the number obtained from square root and r is the remainder that we cant do anything else with.

After doing this, we get the answer 2√10, which can be said "two radical ten"

Hi! I hope you're enjoying your day!

The common factor of 10x and 5 is

5.

What is a factor?

It's a number that a number is evenly divisible by.

Example: 2 is a factor of 10, because 10 is evenly divisible by 2.

Also, it may be tempting to say, "Well, 2 is the common factor!"

And that's not true in this case, because 5 isn't divisible by 2.

x is also not a common factor; 5 is a constant, it doesn't have any variables next to it.

Hence, the factor is

[tex]\boxed{\boxed{\bold{5}}}[/tex]

Kevin works two part-time jobs and wants to earn a total of at least $504 per week. He earns an

average of $12 per hour delivering food and $14 per hour working retail

A.) Write the inequality representing the scenario

B.) Graph the inequality

### Answers

Kevin **earning at least **$504 implies that he wants to earn $504 or more

The **inequality **representing the scenario is [tex]12x + 14y \ge 504[/tex]

How to interpret the scenario?

The given parameters are:

Earnings = At least $504

Food delivering = $12 per hour

Retail = $14 per hour

Represent the number of hours **delivering food **with x, and the **retail work **with y.

So, the **earning **is:

Earning = 12x + 14y

The **earning **is at least $504.

So, we have:
