Answer:
1995
Step-by-step explanation:
Percent of students that get more than 8 hours of sleep = 100 -43 = 57%
Number of students that get more than 8 hours of sleep = 57% x 3500
0.57 x 3500 = 1995 students

Tell whether the angles are complementary or supplementary. Then find the value of $x$ . A ray intersects two other rays forming a right angle. The angles formed after the intersection is x degrees and left parenthesis x minus 20 right parenthesis degrees.
The measure of the value of x is 55°.
We have,
Complementary angles are two angles that add up to 90 degrees.
Supplementary angles are two angles that add up to 180 degrees.
Now,
The ray intersects two other rays forming a right angle.
This means,
It is a complementary angle.
i.e
x + (x - 20) = 90
x + x - 20 = 90
2x = 90 + 20
2x = 110
x = 55°
Thus,
The measure of the value of x is 55°.

Answer:
x would equal 72
Step-by-step explanation:
you can find a percent but there is already a percent showing. So the answer should be 72.
When you're trying to find the answer to these problems you should check if there is a percent part and whole. In this question, there is already a percent and a part so you would just try to find the whole.

What value of b will make the equation a true statement? Explain how you arrived at your solution. (−34 + 43)+ b = 0
Answer:
b = -9
Step-by-step explanation:
Given the equation (−34 + 43)+ b = 0
We are to find the value of b
First solve for the value in parenthesis
(−34 + 43)+ b = 0
9+b = 0
Subtract 9 from both sides
9+b-9 = 0 - 9
b+0 = -9
b = -9
Hence the value of b will make the equation a true statement is -9

What is the area of the base?
Answer:
24 in²
Step-by-step explanation:
Hello there!
the figure shown is a triangular prism
The base is the triangle
So we need to find the area of the triangle using this formula
[tex]A=\frac{bh}{2}[/tex]
where b = base and h = height
The base (triangle) has a base length of 8 inches and a height of 6 inches
Having found the information we needed, we plug it into the formula
So
[tex]A=\frac{6*8}{2} \\6*8=48\\\frac{48}{2} =24\\A=24in^2[/tex]
So the area of the base is 24 in²
Are these similar and what is the reason?
Answer:
yes
Step-by-step explanation:
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size.
The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

Diagonals of a parallelogram bisect each otherGiven vertices:
(-2,-1), (1,3), (6,3), (3,-1)Plot the points.
We see the diagonals are:
(-2,-1) (6,3) and (1,3), (3,-1)The midpoint of any diagonal is the intersection of the diagonals.
Use midpoint formula to find the coordinates:
x = (x₁ + x₂)/2 = (-2 + 6)/2 = 4/2 = 2y = (y₁ + y₂)/2 = (-1 + 3)/2 = 2/2 = 1The point is (2, 1)

Step-by-step explanation:
First, solve 9.30 x 10^7 to find the length of an astronomical unit.
10^7 = 10000000
9.30x10000000=93000000 miles
next, solve for the distances the sun is from Jupiter and Mars,
10^8 = 100000000
1.42x100000000=142000000 miles
4.84x100000000=484000000 miles
next, subtract the distances
484000000-142000000=342000000 miles
then, divide the sum by 93000000 to find the amount in astronomical units.
342000000/93000000=3.677419
finally, round to the nearest hundred

Answer:
x = 7
Step-by-step explanation:
A triangle's total interior angle measurement will equal 180°.
Set all measurements equal to 180:
(82) + (9x - 6) + (6x - 1) = 180
Simplify. Combine like terms:
(82 - 6 - 1) + (9x + 6x) = 180
(82 - 7) + (15x) = 180
(75) + 15x = 180
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, Subtract 75 from both sides of the equation:
15x + 75 = 180
15x + 75 (-75) = 180 (-75)
15x = 180 - 75
15x = 105
Next, divide 15 from both sides of the equation:
(15x)/15 = (105)/15
x = 105/15
x = 7
7 is your value for x.

A shipping container is in the shape of a right rectangular prism with a length of 5 feet, a width of 12.5 feet, and a height of 14 feet. The container is completely filled with contents that weigh, on average, 0.78 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?
Answer:
102 pounds
Step-by-step explanation:
Volume of Right rectangular prism = 12 * 8.5 * 4 = 408 cubic feet
Density = Mass / Volume
=> 0.25 = Weight of contents in container / Volume of container
=> 0.25 = Weight of contents in container / 408
=> Weight of contents in container = 0.25 * 408
=> Weight of contents in container = 102 pounds
Answer:
683lb

Two less than five times a number x is equal to 13. Solve for x.
Answer:
x = 3
Step-by-step explanation:
5x - 2 = 13 (write the equation)
5x - 2 + 2 = 13 + 2 (isolate the variable)
5x = 15
5x/5 = 15/5 (simplify)
x = 3
Answer: x=3
Step-by-step explanation:
13=5x-2
13+2=5x
15=5x
x=15/5
x=3
