If measure of angle 1 = 2x+6 and measure of angle 2 = 8x+4 where angles 1 and 2 are supplementary, then how much is the actual measure of angle 1?\
Answers
Answer:
The actual measure of ∠1 = 40°
Step-by-step explanation:
We are given: ∠1 = 2x+6 and ∠2 = 8x+4
and both angles are supplementary. we need to find the actual measure of ∠1
Supplementary angles: If the angles are supplementary their sum is equal to 180°
In our case ∠1 +∠2 = 180°
2x+6+8x+4=180
Solving the equation to find x, then we can find the actual measure of ∠1
[tex]2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17[/tex]
So, value of x = 17
Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6
[tex]\angle1=2(17)+6\\\angle1=34+6\\\angle1=40[/tex]
So, the actual measure of ∠1 = 40°
Kayla is give a monthly allowance. She puts 40% of the money directly into her savings account. She spends $15 at the movies with her friends. At the end of the month, she has $3 left. How much is her monthly allowance?
Answers
This is because if she has put 40% in to savings she has 60% left. This 60% is 15 + 3 (the money she spent at the movies and the money she has left) = £18
So 60% : £18
10% : £3 (divide by 6)
100% : £30 (multiply by 100)

It would cost $ to serve 24 people.
Answers
Answer:
$39
Step-by-step explanation:
Given parameters:
Cost of ingredient = $9.75
Number of people = 6 people
Unknown:
How much will it cost to serve 24 people = ?
Solution:
To solve this problem, let us find the rate of each recipe per person;
Rate = [tex]\frac{Number of people }{Cost of ingredient}[/tex]
Insert parameters and solve;
Rate = [tex]\frac{6}{9.75}[/tex] = 0.62people/$
For 24 people, it will cost;
Cost of ingredient = [tex]\frac{Number of people }{rate}[/tex]
Cost of ingredient = [tex]\frac{24}{0.62}[/tex] = $39

A local hamburger shop sold a combined total of 591 hamburgers and cheeseburgers on Tuesday. There were 59 fewer cheeseburgers sold than hamburgers
On tuesday how much did they sell
Answers
Answer:
On Tuesday
591 burgers are sold.
Some are hamburgers and some are cheeseburgers.
59 fewer cheeseburgers sold than hamburgers.
Number of cheeseburgers --> x
Number of hamburgers --> y
x+y= 591 --> x = 591-y
x = y-59
so
591-y = y-59
-2y = -650
y = 325
so
x = 325-59
x =266
The hamburger shop sold a combined total of 591 hamburgers and cheeseburgers on Tuesday.
Let's represent the number of hamburgers sold as "H" and the number of cheeseburgers sold as "C." From the information given, we have two equations:
1. H + C = 591 (The combined total of hamburgers and cheeseburgers sold on Tuesday was 591).
2. C = H - 59 (There were 59 fewer cheeseburgers sold than hamburgers).
Now, we can use substitution to solve for the number of hamburgers: Substitute the value of C from the second equation into the first equation:
H + (H - 59) = 591
Now, combine like terms:
2H - 59 = 591
Next, isolate the term with H:
2H = 591 + 59
2H = 650
Now, solve for H:
H = 650 / 2
H = 325
So, they sold 325 hamburgers on Tuesday. To find the number of cheeseburgers sold, use the second equation:
C = H - 59
C = 325 - 59
C = 266
They sold 266 cheeseburgers on Tuesday. To find the total sales, add the number of hamburgers and cheeseburgers: Total sales = 325 (hamburgers) + 266 (cheeseburgers) = 591.

How can we change 1 litre into 1000cm3
Answers
To change from litres into cubic centimetres, you times the value by 1000.
Eg:
Imagine the question “turn 5 litres into cm³”
First step would be to figure out how many litres we have, which is 5.
Now, we multiply 5 by 1000, which gives us 5000.
Therefore 5 litres = 5000cm³

(If I helped you at all I’d greatly appreciate a thanks or if I really helped you a Brainliest!)
Step-by-step explanation:
1 Liter (L) is equal to 1000 cubic centimeters (cm3). To convert liters to cubic centimeters, multiply the liter value by 1000. For example, to convert 2 liters to cubic centimeters, multiply 2 by 1000, that makes 2 L is 2000 cm3.

What is the domain and range for the function graphed to

Answers
Answer:
Domain: (-∞, ∞)

General Formulas and Concepts:
Algebra I
Domain is the set of x-values that can be inputted into function f(x)Range is the set of y-values that are outputted by function f(x)Step-by-step explanation:
We know that the parabola will continue indefinitely, hence we use infinity. Our domain would then be from negative infinity to positive infinity, because we can plug in any number x.
We see the from the graph that the y-value is actually restricted. We have a max value of y = -3, and the graph will never go higher than that. Therefore, our range spans from negative infinity to -3.
Step-by-step explanation: The range of a function
is the set of all y values of the function.
The y values on a coordinate system are the up and down values.
Our parabola is expanding infinitely downwards but
it never goes above the y value of -3.
So we say that the range of this function is {y: y ≤ -3}.
The domain is the set of all x values or left and right values.
Since it's expanding infinitely to the left and right,
we say that the domain is the set of all real numbers or R.
Skylar owns a small business selling bagels. She knows that in the last week 80 customers paid cash, 7 customers used a debit card, and 42 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a credit card as a decimal to the nearest hundredth.
Answers
Answer:
The probability that the next customer will pay with credit card is approximately 0.33
Step-by-step explanation:
The given parameters are;
The number of customers that paid cash = 80 customers
The number of customers that used a debit card = 7 customers
The number of customers that used a credit card = 42 customers
The total number of different payments made = 80 + 7 + 42 = 129 payment
Probability = The number of desired outcome/(The number of possible outcome)
The probability that the next customer will pay with credit card = (The number of customers that used a credit card)/(The total number of different payments made)
∴ The probability that the next customer will pay with credit card = 42/129 ≈ 0.33 to the nearest hundredth.
