Answer: 220 miles
Step-by-step explanation:
(150 miles)/(7.5 inches) = 20 miles/inch
(20 miles/inch)*(11 inches) = 220 miles
The price of a notebook was 3.70 yesterday. Today, the price fell to 3.20. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
The price was dropped around 15%
Step-by-step explanation:
You will pay $3.15 for a item with original price of $3.70 when discounted 15%. In this example, if you buy an item at $3.70 with 15% discount, you will pay 3.70 - 0.555 = 3.15 dollars.
2. French Vanitta K-Cups that originally
cost $5.99 are now on sale for $4.75.
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%

GIVEN THAT TAN Ꝋ= - 4/3 AND Ꝋ IS IN QUADRANT II, FIND SIN 2Ꝋ
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

what is 5*2+4*6+10+123+(8)-1
Answer:
174
Step-by-step explanation:
(10)+(24)+10+123+7
=174
Answer:
174
Step-by-step explanation:
5⋅2+4⋅6+10+123+(8)−1
Multiply 5 and 2 to get 10. Multiply 4 and 6 = 24.
10+24+10+123+8−1
Add 10 and 24 =34.
34+10+123+8−1
Add 34 and 10 =44.
44+123+8−1
Add 44 and 123 =167.
167+8−1
Add 167 and 8 =175.
175−1
Subtract 1 from 175 = 174.

To solve for k in the inequality -16 -32 > -48, what steps are correct?:
A First, subtract 32 to each side, then divide by -16 and flip the sign
B First, divide both sides by 16, then add 32 to both sides and leave
the sign
C First, subtract 48 from both sides, divide by -16 and leave the sign
D First, add 32 to both sides, then divide by -16 and flip the sign
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.
[tex]\frac{-16k}{-16} <\frac{-16}{-16}[/tex]

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.

B. The first day of tryouts they select the first six that show up as they figure those are the most eager for a spot.
C. They place all of the names of the people trying out in a hat and then select six out of the hat. Those are the ones that are chosen.
D. They watch the players during tryouts and then put them on a list in order from the most skilled to the least skilled and then select the top three and the bottom three from the list.
Answer:
A because it's most likely to be like that at tryouts

Steve is an under armor sweatshirt with a normal price of $40 but he uses a 10% off coupon how much does he say if I using this coupon?
Answer: £36
Step-by-step explanation: 10% is a tenth of the whole price (1/10). We would divide 40 by 10 to get 4 (1/10 of 40)- remember you divide by the bottom of the fraction and times by the top. To get the new price, we subtract 4 from 40 to get £36
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)
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).

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?
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

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.
