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°

1.) Simplify the expression by combining like
terms: a + 2a - 3a.
Answers
Answer: 0
Step-by-step explanation:
We can start by factoring out an a from all 3 terms:
= a (1 + 2 - 3)
We can evaluate 1 + 2 - 3 as 0:
= a(0)
Anything multiplied by 0 is 0, therefore 0a = 0.

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"

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:
[tex]12x + 14y \ge 504[/tex]
See attachment for the graph of the inequality

The first step is to set up a porportion like this one
[tex]\frac{?}{15,000} \frac{65}{100}[/tex]
Next, you cross multiply and divide. 15,000 times 65 is 975,000

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.

Answers
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]
Hope everything is clear.

© 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

therefore ,
possible coordinates of A are either ( 1 , -1 ) or ( 1 , 5 )
