Answer:
30 Gallons
Step-by-step explanation:
Ok, lets see the difference the 9 gallons of gas did to Rafael's gas tank.
1/2 --> 0.5
4/5 --> 0.8
0.8-0.5 = +0.3
The tank was made 30% more full with the gas.
Next, we can use this to find the amount of gas which would need to be used to fully fill the tank, given that it was empty.
So to make it easier, say we filled it up a third of 30% to get an easier to work with 10% of fill of the gas tank.
9 / 3 ---> 3 Gallons
Now, multiply this by 10 to get the 100%
3 * 10 = 30 Gallons
All done!

research paper.
auntion to find the time it takes to copy a 50-page
Nii
Answer:
288 points
2 minutes
5 minutes
Step-by-step explanation:
Given that :
Average point per game = 18 points
Number of games played = 16
Total points claimed = number of games played * average points per game
Total points = 18 * 16 = 288 points on average
Print rate = 12 pages per minute
Copying rate = 10 pages per minute
To print a 24 page research paper :
Time taken = number of pages / printing rate
Time taken = 24 / 12 = 2 minutes
To copy a 50 page paper :
Time taken = number of pages / copying rate
Time taken = 50 / 10 = 5 minutes

The population of leave town is 1-23,560 and is decreasing at a rate of 1.5%
each
year.
a) when will the population of Leavetown drop below 47,000 Cto the nearest
year)?
b) what will the population of leavetown be years from now?
Answer: a is correct
Step-by-step explanation:
At 25 years
Step-by-step explanation:
123,000 x 2.375% = 2,921.25. This gives you the rate that the population is decreasing. How long will it take to get to 50,000. Do reverse operations to find this answer: 123,000 - 50,000 = 73,000, the population need to decrease by 73,000 to get to 50,000. So let's multiply our rate of 2,921.25 x 25 = 73,031 and our final step.. 123,000 - 73,031 = 49,969 below 50,000

Answer:
D. They have the same slope, and the same y-intercept so they have infinitely many solutions.
Step-by-step explanation:
Graphing these lines shows that both lines are the exact same line, and cannot have a point of intersection. Solving the equations shows you a value that is ultimately always correct; such as 0=0. This can be used as proof that "They have the same slope, and the same y-intercept so they have infinitely many solutions" because either equation can be rearranged to equal the other.

Using the law that states that the sum of an interior angle of a rectangle is equal to the exterior.
From the given diagram;
m<X + m<Y = m<3
Given that m<X= 55 degrees and m<Y = 50 degrees
m<3 = 55 + 50

Step-by-step explanation:
Can a person train to become better at holding their breath? An experiment was designed to find out. A group of 12 volunteers were randomly assigned to 1 of 2 groups. The 6 volunteers assigned to group 1 were given breath-holding exercises to perform for 2 weeks. The other group was not given any information about the experiment. At the end of the 2 weeks, all 12 volunteers were individually tested to determine how long they could hold their breath. Here are the data (in seconds):
Group 1: 90, 88, 70, 110, 75, 105
Group 2: 40, 48, 35, 50, 55, 62
The researcher would like to determine if these data provide convincing evidence that the true mean amount of time volunteers who were given training held their breath is greater than the true mean amount of time volunteers without training held their breath. The researcher tests H0: μ1 – μ2 = 0, Ha: μ1 – μ2 > 0, where μ1 = the true mean amount of time that volunteers who were given training held their breath and μ2 = the true mean amount of time that volunteers without training held their breath. The conditions for inference are met. The standardized test statistic is t = 5.44. What is the P-value of this test closest to?
Answer is A, 0
The null hypothesis may be significantly rejected. Choose A, 0, for the closest response.
What does "true mean" refer to?In statistics, the term "true mean" refers to the true mean of a population or set of data.
It is typically unknown; hence it is estimated using inferential statistics using a sample.
For group 1, s1²= 250.67
group 2, s2² = 96.27
t= 5.44 which is the difference of mean.
Given the data values:
Group 1: 90 88 70 110 75 105
Group 2: 40 48 35 50 55 62
For group 1, n1 = 6
group 2, n2 = 6
Given that H_o= u1 - u2 = 0
H_a = u1 - u2 > 0
To find the t-test about the difference, we would use the formula to solve.
The totals are displayed below:
x1 = 538
x2 = 290
(x1-x2) ² = 1253.3334
x2-x2= 0
(X2-x2) ² =481.3334
For group 1, s1²= 250.67
group 2, s2² = 96.27
t= 5.44 which is the difference of mean.

Answer:
x=20°
Step-by-step explanation:
x° + 100° + 3x° = 180° => 4x°+100°=180° => 4x=180°-100°=80° => x=80° : 4 = 20° => x=20°
The value of angle x will be equal to 20°.
What is a supplementary angle?If two angles sum up to 180 degrees, they are referred to as supplementary angles. A straight angle is created by supplementary angles (180 degrees)
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that the three angles are x, 3x, and 100 degrees. The value of the angle x will be calculated as below:-
For supplementary angles, the sum of the angles is 180 degrees.
x° + 100° + 3x° = 180°
4x°+100°=180°
4x=180°-100°=80°
x=80° : 4
x=20°
Therefore, the value of angle x will be equal to 20°.

Find the values of m and n.
Answer:
[tex]m=46^{\circ},\\n=22^{\circ}[/tex]
Step-by-step explanation:
From the isosceles-base theorem, the base angles of two equal legs in a triangle must be equal. Thus, we can set the up the following equation to solve for [tex]n[/tex]:
[tex]136+n+n=180,\\136+2n=180,\\2n=44,\\n=\boxed{22^{\circ}}[/tex]
Now that we've found [tex]n[/tex], we can set up the following equation with respect to the largest triangle:
[tex]90+n+m+n=180,\\90+22+m+22=180,\\134+m=180,\\m=\boxed{46^{\circ}}[/tex]
Answer:
M = 46°
N = 22°
Step-by-step explanation:
Value of M:
Sum of angles in triangle = 180°
180° - 90° - (180° - 136°) = m
90° - 44° = m
m = 46°
Value of N:
The triangle is isosceles (marked by the two congruent lines with the tick)
That means that the other two angles, are the same
180° - 136° = 2n
44° = 2n
n = 22°

Challenge A bag contains pennies, nickels dimes, and quarters. There are 50 coins in all of the
coins 18% are pennies and 40% are dimes. There are 2 more nickels than pennies. How much
money does the bag contain
The bag contains S
Answer:
The bag contains $5.14
Step-by-step explanation:
18% of 50 = (.18)(50) = 9 pennies
40% of 50 = (.40)(50) = 20 dimes
2 more nickels than pennies = 9 + 2 = 11 nickels
40 coins so far, so 50 - 40 = 10 quarters
Total value:
9 x ($0.01) = $0.09 for pennies
20 x ($0.10) = $2.00 for dimes
11 x ($0.05) = $0.55 for nickels
10 x ($0.25) = $2.50 for quarters
Grand total value = $5.14

If the pattern continues, which
equatior. could be used to find the nth
term?
Answer:
Option B. m(n) = –5.75 –¼n
Step-by-step explanation:
The sequence is given below:
–6, –25/4, –13/2, –27/4, –7
Next, we shall determine the common difference.
Common difference (d) = 2nd – First
2nd term = –25/4
First term = –6
d = –25/4 – – 6
d = –25/4 + 6
d = –6.25 + 6
d = –0.25 = –¼
Finally, we shall determine the nth term
Tₙ = a + (n –1)d
First term (a) = –6
Common difference (d) = –¼
Tₙ = a + (n –1)d
Tₙ = –6 + (n –1)–¼
Tₙ = –6 –¼n + ¼
Tₙ = –6 + ¼ –¼n
Tₙ = –6 + 0.25 –¼n
Tₙ = –5.75 –¼n
Thus, the nth term is given by:
m(n) = –5.75 –¼n
Is a triangle with the side lengths 4 feet, 7.5 feet, and 8.5 feet a right triangle? Why or why not?
Answer: Yes, it is a right triangle
Step-by-step explanation:
Use the pythagorean theorem in order to determine whether this triangle is a right triangle. Plug in the values given in the problem (4, 7.5, and 8.5) into this equation (a^2+b^2=c^2). This gives you 4^2+7.5^2=8.5^2, and this equation is valid because 4^2+7.5^2 does equal 8.5^2.
Answer:
Yes, because 4^2+7.5^2=8.5^2.
