Jeff is building a bookcase for his room and wants to be sure the shelves are parallel. He measures the angles below and knows the shelves are parallel when he finds which two angles to be supplementary?
Answer:
∠2 and ∠4 are the supplementary angle.
Step-by-step explanation:
Shelves of the bookcase are parallel and a transversal line is intersecting these points at two distinct points.
By the property,
Sum of two interior consecutive angles measure 180°.
From the figure attached,
∠2 and ∠4 are the interior consecutive angles.
Therefore, m∠2 + m∠4 = 180°
Which proves that shelves of the showcase are parallel.

Which relation is a function?
{(1, 2); (2, 3); (3, 4); (1, 5)}
{(1, 2); (1, 3); (3, 2); (4, 2)}
{(1, 2); (2, 5); (3, 2); (4, 5)}
{(1, 2); (2, 3); (3, 4); (2, 5)}
Answer:
the third relation: {(1, 2); (2, 5); (3, 2); (4, 5)}
Step-by-step explanation:
relations can only be a function if the input/x don't repeat at all.
its ok if the output/y repeat though!
{(1, 2); (2, 5); (3, 2); (4, 5)}, best represents the functions. Option C is correct.
Given that,
To determine which relation is a function.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
Here,
For a relation to be a function, for two variables only one of the variables can have a repeated value i.e. dependent variable with respect to the others if the value of both variables is repeating then the relation is not a function. So,
{(1, 2); (2, 3); (3, 4); (1, 5)}
X repeated twice its not the function.
Similarly,
{(1, 2); (2, 3); (3, 4); (2, 5)} and {(1, 2); (1, 3); (3, 2); (4, 2)} are not the function.
But,
{(1, 2); (2, 5); (3, 2); (4, 5)} is function because the value of independent variable is not repeating.
Thus, {(1, 2); (2, 5); (3, 2); (4, 5)}, best represents the functions. Option C is correct.

Tom ate at a restaurant. His bill was $12.00. He left a 15% tip. Determine whether each statement about Tom's payment is true or false.
Answer:
True, True, False, True
Step-by-step explanation:
$12.00 ⋅ 0.15 = $1.80
Tom paid $1.80 as tax. That takes care of the second question.
$12.00 + $1.80 = $13.80
So Tom paid more than $12.00 for his meal. That takes care of the first question.
We already know that Tom paid $1.80 as tax. So we know the third question is not right.
And we already know that $12.00 + $1.80 = $13.80. So the fourth question is correct.

if a sample of 35 golfers is taken from a population of 72 golfers the sample mean, x, is the mean of how many golfers scores
Answer: 35
Step-by-step explanation:
The sample mean, denoted by (pronounced "x bar"), represents the average value of a given variable in a sample. In this case, we are trying to find the sample mean of golfers' scores.
To calculate the sample mean, we need to sum up all the individual scores in the sample and divide by the number of golfers in the sample. Given that we have a sample of 35 golfers from a population of 72 golfers, we can conclude that the sample mean, , represents the mean of the scores of these 35 golfers.
Mathematically, the formula for calculating the sample mean is: = (x1 + x2 + x3 + ... + xn) / n where x1, x2, x3, ..., xn represent the individual scores, and n represents the sample size. Therefore, the sample mean, , is the average of the scores of the 35 golfers in the sample. To find the exact value, you would need to know the actual scores of each golfer.

b I think t or t(s) is the dependent variable since the total amount of money depends on how many treats are sold.
t(32) = 30 + 2(32)
t(32) = 30 + 64

Diana baked 39 cookies with 3 scoops of flour. How many scoops of flour does Diana need in
order to bake 169 cookies? Solve using unit rates.
Answer:
Diana needs 13 scoops of flour to bake 169 cookies.
Step-by-step explanation:
well, first you need to find the unit rate.
if 3 scoops of flour makes 39 cookies,
then 1 scoop of flour makes 13 cookies. (39/3)
next, since the unit rate is 13 cookies per flour-scoop, divide 169 by 13 to get your answer.
169/13 = 13
