Answer:
x=8
y=3
Step-by-step explanation:
the triangle on the right side is equilateral, therefore also equiangular, which means each angle is 60 degrees
that means that 4x-2 = 30; 4x = 32; x = 8
also means that 7y+9 = 180-(90+60); 7y+9 = 30; 7y = 21; y = 3

For each 16 unit increase in x, you get a 6 unit increase in y.
So, you can approach this with the idea of slope (change in y over change in x) to have a slope of 6/16 or 3/8.
y = 3/8 x
This checks out with all of those values.
2. French Vanitta K-Cups that originally
cost $5.99 are now on sale for $4.75.
Answers
Answer:
20.7% is the % decrease.
Step-by-step explanation:
If you are finding the % of decrease then see below.
% Decrease = (Original Cost - New Cost ) ÷ Original Cost × 100
5.99 - 4.75 = 1.24
1.24 ÷ 5.99 = .2070
.2070 × 100 = 20.7%

Pam makes 5 liters of apple juice. She saves 0.5 liter of apple for dinner and puts the rest in bottles . If each bottle bottle holds 0.75 liter, how many apples of apple juice can pam fill?
Answers
Pam can fill 6 bottles of apple juice.
The number of bottles she can fill if, Pam makes 5 liters of apple juice. She saves 0.5 liters of apples for dinner and puts the rest in bottles is 6.
What is multiplication?One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.
Given:
Pam makes 5 liters of apple juice. She saves 0.5 liters of apples for dinner and puts the rest in bottles,
If each bottle holds 0.75 liters,
Calculate the amount of juice left as shown below,
The amount of juice left = 5 - 0.5
The amount of juice left = 4.5 liter,
Calculate the number of bottles as shown below,
The number of bottles = The amount of juice left / juice held by each bottle
The number of bottle = 4.5 / 0.75
The number of bottles = 6

The system is inconsistent because the slopes are the same and the lines are different.
A linear equation is of the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Given the following system of equations:
y = 6x + 2 (1)
y = 6x + 1 (2)
We can see that both equations have the same slope of 6 but have different y intercepts.
Hence the system is inconsistent because the slopes are the same and the lines are different.

The cost of a baguette and a cup of hot chocolate is $1.45. The cost of 2 baguettes and a cup of hot chocolate is $2.10. What is the cost of one cup of hot chocolate?
Answers
Answer:
It is $0.8
Step-by-step explanation:
First find out the value of one baguette.
They just added one more baguette. So the amount left after subtracting them both will be the cost of 1 baguette.
2.10 - 1.45 = 0.65
Now, subtract the 1st cost with the cost of 1 baguette.
1.45 - 0.65 = $0.8

A National Institute of Health survey of 40467 U.S adults found that 3156 of them experienced at least one major depressive episode in the previous year. Make a 95% confidence interval for the proportion of all U.S. adults who experienced depression in that year. (Source: https://www.nimh.nih.gov/health/statistics/major-depression)
Answers
Using the information given, it is found that the 95% confidence interval for the proportion of all U.S. adults who experienced depression in that year is (0.075, 0.081).
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].
3156 out of 40467 adults experienced depression, hence:
[tex]n = 40467, \pi = \frac{3156}{40467} = 0.078[/tex]
95% confidence level
So [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.078 - 1.96\sqrt{\frac{0.078(0.922)}{40467}} = 0.075[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.078 + 1.96\sqrt{\frac{0.078(0.922)}{40467}} = 0.081[/tex]
The 95% confidence interval for the proportion of all U.S. adults who experienced depression in that year is (0.075, 0.081).

To solve for k in the inequality -16 -32 > -48, what steps are correct?:

the sign
C First, subtract 48 from both sides, divide by -16 and leave the sign

Answers
Answer:
D. First, add 32 to both sides, then divide by -16 and flip the sign
Step-by-step explanation:
Taking that the inequality is -16k-32>-48
First you have to get rid of any addition or subtraction, in this case you have to get rid of -32 by adding 32 to each side:
-16k-32+32 > -48 +32
Then you need to divide by -16 and flip the sign because you are dividing by a negative number and if you don't flip the sign the inequality will be false.

In which set do all of the values make the inequality 3k – 6 < 12 true?
Answers
The set of values that satisfies the inequality is (-∝, 6)
Inequality shows the non-equal comparison between two numbers or other mathematical expressions.
Given the inequality: 3k – 6 < 12
Solving the inequality:
3k – 6 < 12
Add 6 to both sides:
3k - 6 + 6 < 12 + 6
3k < 18
Divide both sides of the equation by 3:
3k/3 < 18/3
k < 6
The set of values that satisfies the inequality is (-∝, 6)

GIVEN THAT TAN Ꝋ= - 4/3 AND Ꝋ IS IN QUADRANT II, FIND SIN 2Ꝋ
Answers
Answer:
sin 2θ = -24/25
Step-by-step explanation:
see the below formula of sin x in terms of tan x
by substituting => -4/3 / ± √(16/9 + 1)
=> -4/3 / ± √(25/9)
=> -4/3 / ± 5/3
=> ± -4/5
=> ± 4/5
as theta is in second quadrant is in 2nd quadrant sin value is positive
so sin θ = 4/5 and cos θ = -3/5
now sin 2θ = 2 sinθcosθ
= 2 * 4/5 * -3/5
= -24/25
