Answer:
The amount of time Jill spent to do her homework
= 9 1/2 hours. which equals to 570 minutes.
Which means, the amount of times Jack needed to do his is
= 570 minutes x 1.5
= 855 minutes which equals to 14 1/4 hours
hope this helps
Answer:
Step-by-step explanation:
1) Time spent by Jack = Time spent by Jill * 1 1/2
[tex]= 9\frac{1}{2}*1\frac{1}{2}\\\\=\frac{19}{2}*\frac{3}{2}\\\\=\frac{19*3}{2*2}\\\\=\frac{57}{4}\\\\=14\frac{1}{4} hours[/tex]
2) Time spent by Jill = Time spent by Jack ÷ 1 1 /2
= 18 1/4 ÷ 1 1/2
= 73/ 4 ÷ 3/2
[tex]= \frac{73}{4} * \frac{2}{3}\\\\=\frac{73}{2}*\frac{1}{3}\\\\=\frac{73*1}{2*3}\\\\=\frac{73}{6}\\\\=12\frac{1}{6} hours[/tex]
3) Third number = Sum of three numbers - Sum of two numbers
Sum of two numbers = [tex]8\frac{2}{3}+8\frac{1}{6}\\[/tex]
[tex]= \frac{26}{3} +\frac{49}{6}\\\\=\frac{26*2}{3*2}+\frac{49}{6}\\\\=\frac{52}{6}+\frac{49}{6}\\\\=\frac{52+49}{6}\\\\=\frac{101}{6}\\[/tex]
Third number = 22 8/15 - 101/6
[tex]= \frac{338}{15}- \frac{101}{6}\\\\= \frac{338*2}{15*2}- \frac{101*5}{6*5}\\\\= \frac{676}{30}- \frac{505}{30}\\\\= \frac{676-505}{30}\\\\= \frac{171}{30}\\\\=5 \frac{21}{30}\\\\= 5 \frac{7}{10}[/tex]

Solve this system of equations: 3x-2y=2 5x-5y=10
Answers
Answer:
(- 2, - 4 )
Step-by-step explanation:
Given the 2 equations
3x - 2y = 2 → (1)
5x - 5y = 10 → (2)
Multiply (1) by 5 and (2) by - 3, then add to eliminate x
15x - 10y = 10 → (3)
- 15x + 15y = - 30 → (4)
Add (3) and (4) term by term to eliminate x , that is
5y = - 20 ( divide both sides by 5 )
y = - 4
Substitute y = - 4 into either of the 2 equations and solve for x
Substituting into (1)
3x - 2(- 4) = 2
3x + 8 = 2 ( subtract 8 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
Solution is (- 2, - 4 )

The kingdom of Arendelle is trying to decide who to send to the regional track meet. Anna, Elsa, and Olaf competed in the long jump and their 6 jumps are shown below (in meters). Kristoff says that Olaf has the longest average, so he should be sent to the track meet. Do you agree or disagree? Why?
Answers
Please find table attached
Answer:
Agree: Olaf should be sent to the track meet because he has the longest average
Step-by-step explanation:
To ascertain if this is true, we must calculate the average for each athlete
Mean or average of athlete= total score of jumps/ number of jumps
Average for Anna= 3.25+3.95+4.28+2.95+3.66+3.81/6 = 3.65
Average for Elsa=3.55+3.88+3.61+3.97+3.75+3.59/6
=3.725
Average for Olaf=3.67+3.78+3.92+3.62+3.85+3.73/6
= 3.76
Therefore Olaf has the longest average =3.76

Her Step 2:
[tex]9 + 23 * 4[/tex] --- This is correct because she solved 3^2 as 9
Her Step 3:
[tex]9 + 9 * 4[/tex] --- This is incorrect because 23 * 4 is not equivalent to 9 * 4

A private university is accepting applications for enrollment. Out of 2,000 applicants, 950 meet the GPA requirements, 600 volunteer for community service, and 250 both meet the GPA requirements and volunteer. Which statement correctly describes the probability that an applicant meets the GPA requirements or volunteers?
Answers
The best answer is Because some applicants volunteer and meet the GPA requirements, the events are not mutually exclusive. Thus the probability is 65%.
What is the probability of meeting the GPA requirements or volunteers?The fact that some people could meet both the GPA requirement and the volunteering requirements means that these are not mutually exclusive.
The probability of meeting both would be:
= (Number of people who met either GPA requirements or Volunteer) / Total number of people
= (950 + 600 - 250) / 2,000
= 0.65
= 65%

What are the coordinates of point Q? On a coordinate plane, point Q is 4 units to the right and 2.5 units up. (Negative 4, 2 and one-half) (Negative 2 and one-half, 4) (2 and one-half, 4) (4, 2 and one-half)
Answers
Answer:
(4, 2 and one-half)
Step-by-step explanation:
Since, point Q is 4 units to the right and 2.5 units up. Both the coordinates of point Q are positive.
Therefore, Q = (4, 2 and one-half)
The coordinates of point Q will be Q(4, 2.5).
What are coordinates?The coordinates in rectangular cartesian system are of the form -
(x, y)
where -
{x} - distance along x - axis.
{y} - distance along y - axis.
Given is the point Q.
It is given that point Q is 4 units to the right and 2.5 units up. So, the coordinates of point P, will be (4, 2.5).
Therefore, the coordinates of point Q will be Q(4, 2.5).
