Answer:
x=7/2y − 7
Step-by-step explanation:
Let's solve for x.
−2x+7y=14
Step 1: Add -7y to both sides.
−2x+7y+−7y=14+−7y
−2x=−7y+14
Step 2: Divide both sides by -2.
−2x/−2 = −7y+14/−2
x=7/2y − 7

On a math test, Rosie answered 36 questions correctly, which was 72%. how many questions were on the test?
Answer:
50
Step-by-step explanation:
What I did first is I converted 72% into a decimal (I work better with decimals), giving me 0.72. Then I solved the equation 36/0.72=x.
x = 50
Answer:
50 questionsStep-by-step explanation:
Let the number of questions be x.
We have:
72% of x is 36.Build an equation and solve for x:
0.72x = 36x = 36/0.72x = 50if a person walks 1/3 a mile in each 1/2 hour, how far does he walk in 1 hour.
Distance travelled in 30 minutes = 1/3 miles
Distance travelled in 1 minute = 1/(3 × 30)
Distance travelled in 60 minutes = (1 × 60)/(3 × 30)
= 2/3 miles

1 * 8.79 = $8.79
we add up all these numbers, 28.14

1 piece of strong board = $12.95
2 boards = $3.20 each (2 x 3.20 = $6.40 total)
10 foot post = $8.79
$12.95 + $6.40 + $8.79 = $28.14
$20 - $28.14 = -$8.14
The total price $28.14
He would need $8.14 more

Latisha owns two spas, one in Pine township and the other in Adams township. Each spa offers a 30-minute face, head, and neck massage to reduce muscle tension. However, therapists first ask each patient questions about their type of tension and stop about five minutes before the end of the 30 minutes to have time to prepare for the next patient. The number of minutes each therapist massages the patients at both spas is approximately Normally distributed, with the Pine spa having a mean of 22.6 minutes and a standard deviation of 1.7 minutes and the Adams spa having a mean of 21.0 minutes and a standard deviation of 2.8 minutes. If Latisha randomly selects 8 massage times from Pine and 9 from Adams, what is the probability that the mean time for Pine is longer than the mean time for Adams? 0.0748 0.7157 0.8264 0.9252

A fire ranger on a 150-ft-tall tower spots a fire at a 30° angle of depression. How
many feet away from the tower is the fire to the nearest tenth?
Answer:
259.8ft
Step-by-step explanation:
The distance from the tower to the fire to the nearest tenth is 260 feet.
Let the adjacent side be a.Given the following data:
Angle of depression = 30°.Opposite side = 150 feet.To determine how far away (in feet) from the tower is the fire to the nearest tenth:
How to apply trigonometric function.In order to solve this exercise, we would form a mental image of the scenario being described. The height of the tower is the opposite side while the distance from the tower to the fire is the adjacent side.
Next, we would apply the Tan trigonometric function:
[tex]Tan \theta = \frac{Opp}{Adj} \\\\Tan 30=\frac{150}{a} \\\\a=\frac{150}{Tan 30} \\\\a=\frac{150}{0.5774}[/tex]
a = 259.79 ≈ 260 feet.

Find the measure of CDE.
The figure is not drawn to scale.
Applying the central angle theorem, the measure of arc CDE is: 172°.
What is the Central Angle Theorem?According to the central angle theorem, the measure of the central angle equals the measure of its intercepted arc.
Measure of arc CDE = 360 - m∠COE [central angle theorem]
Measure of arc CDE = 360 - (103+50+35)
Measure of arc CDE = 172°

figure in the pattern?
Answer:
D
Step-by-step explanation:
The pattern is each end of the figure is expanding by one. A and C are automatically out because there is nothing in the middle of any figure in the previous pattern. B is out because it is the same as figure three. D is correct because it follows the rule of the pattern by expanind outwards one block on each end.

Answer:
the last option -5 ≤ x ≤ 3
Step-by-step explanation:
Because the line there means what x can be so x has to be grater than -5 but less then 3 because the line does not go over 3.
Answer:
- 5 ≤ x ≤ 3.
Step-by-step explanation:
The range of the required values is in the bold line.
The solid circles at the end of the bold line mean the values at these points are included in the inequality.
So it is:- x is greater than or equal to -5 and less than or equal to 3.
That is - 5 ≤ x ≤ 3.

A research group is comparing the learning outcomes of students who are taught a lesson using four different teaching techniques. There are 75 students in the school who can participate in the experiment. Using a table of random digits, the researchers will randomly place the students into five equally sized treatment groups suitable for comparison, four of which will receive a different teaching technique and one of which will remain a control group.
Which design is the most appropriate for this experiment?
A Randomly number each person with 1, 2, 3, 4, or 5. Assign the students to the treatment groups based on their label.
B Select a student, and identify the first digit reading from left to right on a random number table. If the first digit is 1 or 2, assign that student to the technique 1 group. Similarly, digits 3 or 4, 5 or 6, 7or 8, and 9 or 0 go with the technique 2, technique 3, technique 4, and control groups, respectively. Repeat this process for each student.
C Number each student from 1 to 75. Reading the numbers from left to right on a random number table, identify 60 unique numbers from 1 to 75. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.
D Number each student from 00 to 74. Reading the numbers from left to right on a table of random numbers and looking at two digits at a time, identify 60 unique two-digit numbers from 00 to 74. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.
