It took a plane 2 hours to fly from Dallas to New York with the headwind and 1.5 hours to return with the tailwind. If the speed of the wind was 30 mph, how far apart are the two cities?
Answer:
The distance between the two cities is 360 miles.
Step-by-step explanation:
Let a equal the airspeed of the plane in still air; and d be the distance between the two cities. Then:
d/a+30=1.5
d=1.5a+45
and
d/a-30=2
d=2a-60
So
2a-60=1.5a+45
.5a=105
a=210
d/210-30=2
d=360
The distance between the two cities is 360 miles.

In the bar model above, the discount is 20%.What percent of the regular price is the sale price?Explain how you could solve the problem using this information.
Answer:
80%
Step-by-step explanation:
It is in the question (2nd paragraph). 100% is 1 whole, and if 20% is taken away, then it would be 100 - 20, which is 80. Therefore, it is 80%.
The percent of the regular price that is the sale price, given the bar model given is 80 %
How to find the percentage ?The discount is 20 % which means that the sale price of the item is :
= Regular price x ( 1 - discount rate )
= 28 x ( 1 - 20 % )
= 28 x 80 %
= $ 22. 40
The percentage that this is of the regular price is :
= Sales price / Regular price x 100 %
= 22. 40 / 28 x 100 %
= 0. 8 x 100 %
= 80 %

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Find the value of x. Then find the angle measures of the polygon.
Answer:
x° = 125°
(x+10)° = 135°
Step-by-step explanation:
Given:
Sum of measures of angle = 720°
Solution:
We know that:
Sum of measures of angle = 720°
120 + 100 + 120 + x + 10 + 120 + x = 720
x + x + 120 + 100 + 120 + 10 + 120 = 720
2x + 470 = 720
2x = 720 - 470
2x = 250
Divide both sides by 2
x = 250/2
x = 125
Now,
Angles measures
x° = 125°
(x+10)° = (125+10)° = 135°

Find the 24th term.
-9, 0, 9, 18, 27, ...
24th term = [? ]
Answer:
198
Step-by-step explanation:
Answer: 198
Step-by-step explanation:
Firstly, you must find the nth term.
the sequence is: -9, 0, 9, 18, 27, ...
find the difference between each term. in this sequence, the difference is 9, so it is 9n
then you must find the difference between the sequence 9n and this sequence. 9n is:
9, 18, 27, 36, 45, ...
now find the difference between 9n and our sequence.
adjustment = -18
so the nth term is 9n - 18
now you need to substitute 24, as that is the term you would like to find out, in place of n.
so, our n term looks like this: 9(24)-18
9 x 24 = 216
216 - 18 = 198
hence, the answer is 198.

A right triangle is drawn on graph paper. The length of the legs measure 1.5 centimeters and 2 centimeters. The length of the hypotenuse measures 2.5 centimeters. Write an equation using the triangle’s side lengths to show the Pythagorean Theorem holds true for the triangle.
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
In this case, let's denote the lengths of the legs as a = 1.5 centimeters and b = 2 centimeters, and the length of the hypotenuse as c = 2.5 centimeters.
The equation using the triangle's side lengths to show the Pythagorean Theorem holds true for the triangle is:
a^2 + b^2 = c^2
Substituting the given values, we have:
(1.5)^2 + (2)^2 = (2.5)^2
2.25 + 4 = 6.25
6.25 = 6.25
Therefore, the equation holds true, confirming that the Pythagorean Theorem is satisfied for the given right triangle.

edward deposited $7,500 into a savings account 5 years ago. The simple interest rate is 5%. How much money did earn in interest?
Answer:
Edward earned $1,875 in interest.
Step-by-step explanation:
The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.
Here, p = $7,500, r = 0.05 and t = 5 years, and so the interest earned was
i = ($7,500)(0.05)(5) = $1,875.
Edward earned $1,875 in interest.
