Answer:
150 square feet
Step-by-step explanation:
Step 1
Find the Length and Width of the backyard
The length of a rectangular backyard is 5 feet longer than the width of the backyard. The perimeter of the backyard is 50 feet.
Perimeter = 2L + 2W
L = Length, W = Width
L = 5 + W
Hence:
50 = 2(5 + W) + 2W
50 = 10 + 2W + 2W
Collect like terms
50 - 10 = 4W
40 = 4W
W = 40/4
W = 10 feet
We find L
L = 5 + W
L = 5 + 10 feet
L = 15 feet
Step 2
What is the area of the backyard?
Area of a rectangle = Length × Width
Area of the rectangular backyard = 15 feet × 10 feet
= 150 square feet

Steve started with $250 and spent $20 per week. Chelsea started with nothing but saved $30 per week. Use x for time and y for savings.
Write an equation to represent Steve's situation.
Answer:
[tex]250 - 20x=y[/tex]
Step-by-step explanation:
As per the given problem, Steve starts with $250, and spent $20 a week, the problem mentions nothing about Steve's savings, therefore, one can assume that they didn't save anything. As the problem requests, parameter ([tex]x[/tex]) will be used for the time, and ([tex]y[/tex]) for the savings.
Steve's saving would be equal to his initial value, minus his expense, in essence;
[tex]250 - 20x=y[/tex]
The initial value, minus the amount spend per week multiplied by the week number will equal the savings left.
Answer:
y=250-(20x)

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.

g(x) = [tex]\sqrt{11-4x}[/tex]
[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
[tex](\frac{f}{g})(x)=\frac{1-x^2}{\sqrt{11-4x}}[/tex]

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.

Answer:
A = 65deg
B = 78deg
Step-by-step explanation:
It's a triangle, so we know that the sum of angles is 180deg
x + (2x - 9) + (2x + 4) = 180
5x - 5 = 180
5x = 185
x = 37
Measure of angle A = (2*37 - 9)deg = 65deg
Measure of angle B = (2*37 + 4)deg = 78deg

On day one sold 23 tickets on day two sold 25 tickets and on day three the sold 35 tickets if they want to equally share the number of tickets between them how many ticket sales will each boy have
Answer: 41.5
Step-by-step explanation:
Number of tickets sold on day one = 23
Number of tickets sold on day two = 25
Number of tickets sold on day three = 35
Total tickets sold = 23 + 25 + 35 = 83
Since they want to share it equally, each boy will have:
= 83/2
= 41.5
