Find the value of x. Round nearest tenth.
Answer:
x = 53.7 degrees
Step-by-step explanation:
[tex]tan = \frac{opposite}{adjacent}[/tex]
[tex]tan x = \frac{15}{11}[/tex]
tan x = 1.36
tan-1 of 1.36 = 53.7
A middle school has a student population of 800 students. A random group of 60 students at the school were asked if they would vote for a tiger as a school mascot. All but 3 of these students said they would vote for a tiger as a mascot. Based on this survey, which number is a reasonable prediction for the number of students out of the total student population who would most likely vote for a tiger as a mascot?
Answer:
400
Step-by-step explanation:
i think you should revise the q. it looks incorrect...
all but 3 students said they would NOT vote for a tiger...** if that"s the thing then this answer is correct did it by ratio file is attatched:)
A piece of copper tubing is in the shape of a hexagonal prism. The area of the base of the prism is 3 square centimeters. The volume of the prism is 51 cubic centimeters. What is the height of the tubing?
Answer: 17 cm
Step-by-step explanation:
For a regular figure where the area of the base is B, and the height is H, the volume is calculated as:
V = B*H
Here we know that the base of the prism is B = 3 cm^2, and the volume of the prism is 51 cm^3
Then:
B = 3cm^2
V = 51cm^3
If we replace those in the equation above, we get:
51 cm^3 = (3cm^2)*H
Solving this for H gives:
(51 cm^3)/(3 cm^2) = H = 17 cm
The height of the tubing is 17 cm
In an endurance race, Alyson rode her bicycle 7 miles less than Jeff. Together they rode 39 miles. How far did Alyson ride?
Answer:
Distance cover by Alyson = 16 miles
Step-by-step explanation:
Given:
Distance cover together = 39 miles
Assume;
Distance cover by Jeff = a
Distance cover by Alyson = a - 7
Find:
Distance cover by Alyson
Computation:
a + (a - 7) = 39
2a - 7 = 39
2a = 46
a = 23
Distance cover by Alyson = a - 7
Distance cover by Alyson = 23 - 7
Distance cover by Alyson = 16 miles
What is the area of the polygon below.
Answer:
336 ft²
Step-by-step explanation:
The figure is composed of a rectangle and a right triangle
A of rectangle = length × breadth = 24 × 12 = 288 ft²
A of Δ = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 32 - 24 = 8 ft and h = 12 , then
A of Δ = [tex]\frac{1}{2}[/tex] × 8 × 12 = 4 × 12 = 48 ft²
composite area = 288 + 48 = 336 ft²

PLS HELP a parabola has the equation y = 4x^2 + bx -2 and the equation for the axis of symmetry is x = -1.
Answer:
Step-by-step explanation:
Remark
Unless you know calculus, the only way to solve this is by completing the square.
Solution
y = 4x^2 + bx - 2
y = 4(x^2 + b/4 ) - 2
y = 4(x^2 + b/4 + (1/2b/4)^2 ) - 2 - 4*(b/8)^2
y = 4(x^2 + b/4 + (b/8)^2 ) - 2 - b^2/16
y = 4(x + b/8)^2 - 2 - b^2/16
Now what you want to happen is to give b/8 a value of 1 so that when x is put in -1 you get 0 for what is inside the brackets.
b/8 = 1
b = 8
y = 4(x + 1)^2 - 2 - (8)^2 / 16
y = 4(x + 2)^2 - 2 - 4
y = 4(x + 1)^2 - 6
The vertex is at (-1, - 6)
The axis of symmetry is x = - 1
Note
This could have been done a lot shorter just by realizing that the number inside the brackets had to be + 1 as in (x + 1). But then you would not have been able to know the minimum value for y which is - 6

Leon has $50 in a savings account that earns 10% interest, compounded annually. To the nearest cent, how much interest will he earn in 2 years?
Answer:
$10.50
Step-by-step explanation:
Interest = future value - amount saved
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
$50 x (1.1)^2 = $60.50
Interest = $60.50 - $50 = $10.50

At a school bake sale, all of the pies were cut into 6 pieces, so each person who bought a piece got ⅙ of a pie. Each slice sold for $2. The were sold out. How much money did the kids make if there were 11 pies sold? B. How many slices were sold?
Answer:
They made 132$, and 66 slices were sold.
Step-by-step explanation:
If all of the pies were cut into six pieces, and each piece costed $2, then you can multiply 6 x 2 to determine how much each pie cost. ($12)
If each pie costed $12 and there were 11 pies sold in total, then you can multiply 12 x 11 to find out how much money they made.
And to find out how many slices they sold you just have to multiply the 11 total pies by 6 because each pie had six pieces.

Find the x- and y-intercepts of the graph of 3x + 2y = 20. State your answers as
whole numbers or as improper fractions in simplest form.
The x-intercept is given by the coordinates as (x, 0)
i,e y = 0
The y-intercept is given by the coordinates as (0, y)
i.e x = 0
The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3
The y-intercept of the graph of 3x + 2y = 20 is at y = 10
What are coordinates in a graph?
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
3x + 2y = 20
The x-intercept is given by the coordinates as (x, 0)
i,e y = 0
The y-intercept is given by the coordinates as (0, y)
i.e x = 0
Now,
3x + 2y = 20
Putting x = 0 in (1) we get the y-intercept.
3x + 2y = 20
3x0 + 2y = 20
0 + 2y = 20
2y = 20
Divide both sides by 2.
y = 20/2
y = 10
Putting y = 0 in (1) we get the x-intercept.
3x + 2y = 20
3x + 2 x 0 = 20
3x + 0 = 20
3x = 20
Divide both sides by 3.
x = 20/3
Thus,
The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3
The y-intercept of the graph of 3x + 2y = 20 is at y = 10
