If z is inversely proportional to r, and z=32 when r=1.5, find r when z=8.
Answer:
votes
z is inversly proportional to r then z = k/r
zr = k
If z = 32 when r = 1.5
32(1.5) = k
48 = k
k = 48
If z = 8 then r = ?
8r = k
8r = 48
Divide to each side by 8.
r = 48/8
r = 6

A man is standing next to a 24 ft tree. The man is 7ft tall with a shadow of 3ft. How long is the shadow of the tree?
Answer:
[tex]\approx10.29\text{ feet}[/tex]
Step-by-step explanation:
Please refer to the attachment.
By AA Similarity, the two triangles are similar.
Therefore, corresponding parts of them are proportional.
Therefore, we can write the following proportion:
[tex]\frac{7}{24}=\frac{3}{x+3}[/tex]
We will solve for x. Cross-multiply:
[tex]7(x+3)=24(3)[/tex]
Distribute:
[tex]7x+21=72[/tex]
Subtract 21 from both sides:
[tex]7x=51[/tex]
Divide both sides by 7. So, the value of x is:
[tex]x\approx7.2857[/tex]
However, that is only the value of x.
The shadow of the tree is (x+3).
Hence, we will need tot add 3 to our value. Therefore, the actual length of the shadow of the tree is approximately:
[tex]\approx10.2857\approx10.29\text{ feet}[/tex]

Answer:
The slope of this line is -2/3x.
Step-by-step explanation:
The slope can be found by getting x1 and y1 (0,3) and x2 and y2 (3,1). Once you have these you would do y2 - y1 / x2 - x1.
And the equation then is
1 - 3 / 3 - 0. After simplifying this you get -2/3.

Students need at least 75 hours of volunteer service to meet their graduation requirements. Sally has already completed 48 hours. Write and solve an inequality to determine how many more hours Sally needs to complete.
Answer:
48+x=75
Step-by-step explanation:
Subtract 48 from both sides. 75-48 is equal to 27. x=27
Answer:
x [tex]\geq[/tex] 27
Sally has to complete at least 27 more hours
Step-by-step explanation:
Let x represent the number of hours she will complete next
Since students need at least 75 hours, use a greater than or equal to sign.
The total number of hours that Sally will complete can be represented by
x + 48, since she has already done 48 hours.
Use the greater than or equal to sign, and put 75 on the other side:
x + 48 [tex]\geq[/tex] 75
Next, solve the inequality:
x + 48 [tex]\geq[/tex] 75
x [tex]\geq[/tex] 27
So, Sally has to complete at least 27 more hours.
At the end of a snow storm, Emily saw there was a lot of snow on her front lawn. The
temperature increased and the snow began to melt at a steady rate. There was a depth
of 15 inches of snow on the lawn when the storm ended and after 4 hours, the depth
of snow was down to 12 inches. Write an equation for S, in terms of t, representing
the depth of snow on Emily's lawn, in inches, t hours after the snow stopped falling.
Answer: S
Submit Answer
Oh
Answer:
[tex]y = \frac{4}{3}x + 15[/tex]
Step-by-step explanation:
•First we must find out how many inches of snow melted so we can find the slope.
15 inches - 12 inches = 3 inches
•The snow melts 3 inches every 4 hours. This statement can be rewritten as:
[tex]\frac{4}{3}[/tex]
•We know that the snow started at 15 inches so that will be our y-int.
•Now we can start combining these terms to create an equation.
[tex]m = \frac{4}{3}[/tex]
[tex]b = 15[/tex]
•All we have to do is substitute these terms for the corresponding variables.
[tex]y = mx +b[/tex] → [tex]y = \frac{4}{3}x + 15[/tex]
[tex]y = \frac{4}{3}x + 15[/tex]

Each day, the cafeteria serves more than 200 apples with lunch. Write an inequality that represents this situation. Let a represent the number of apples.
The expression for the inequality is written as a > 200.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that each day, the cafeteria serves more than 200 apples with lunch.
The inequality will be written as,
a > 200

(x - 3)^2/9 - (y - 2)^2/16 = 1 The vertices of the hyperbola are:
(-1, 2) and (7, 2)
(3, 6) and (3, -2)
(0, 2) and (6, 2)
To determine the vertices of the hyperbola using the equation[tex](x - 3)^2/9 - (y - 2)^2/16 = 1,[/tex] we can identify the values of a and b, where a represents the distance from the center to the vertices along the x-axis, and b represents the distance from the center to the vertices along the y-axis Therefore the correct option is D.
The given equation can be written as ([tex]x - 3)^2/3^2 - (y - 2)^2/4^2 = 1[/tex], which indicates that [tex]a^2 = 9[/tex] and[tex]b^2 = 16[/tex]. Taking the square root of a^2 and b^2 yields a = 3 and b = 4. The center of the hyperbola is (3, 2), and since the vertices are symmetrical about the center along the x-axis, the vertices can be found by subtracting and adding a from the x-coordinate of the center.
Consequently, the vertices of the hyperbola are (0, 2) and (6, 2). In summary, the vertices of the given hyperbola are located at (0, 2) and (6, 2).
Therefore the correct option is D
