Answer:
3
Step-by-step explanation:
3x - 1 < 8
Solve this inequality like a two-step equation.
Add 1 to both sides to cancel the -1.
3x - 1 < 8
3x < 9 Divide both sides by 3 to cancel the 3 in 3x.
x < 3
Find the absolute value (distance the number is from 0).
Absolute value = 3

Answer:
SA = 434 ft^2
Step-by-step explanation:
We are going to exclude the floor since we are assuming he won't paint the floor. The shed has 5 sides since we aren't going to consider the floor.
length - L
width - W
height - H
surface area - SA
H = 8 ft
L = 14 ft
W = 7 ft
To calculate the area of each side or surface of the shed,
since there are two sides/ surfaces with the same are except for the roof, we will multiply the areas by 2.
Surface area:
SA = 2 × (W×H + L×H) + L×W
SA = 2 × (7×8 + 14×8) + 14×7
SA = 434 ft^2

If two angles are complementary in a right triangle, then explain how you can find the
value of x if sin 440 = cos x using 2-3 sentences. In the last sentence, give the value of x.
Answer:
46°
Step-by-step explanation:
Points of note
two angles are complementary in a right trianglesin 44° = cos x°Solving
The first thing to understand is "complementary" means that the two angles add up to 90°Therefore, 44 + x = 90x = 46°Answer:
46°
Step-by-step explanation:
Complementary angles
Two angles whose measures sum to 90°
In a right triangle, the angle opposite the hypotenuse is always 90°.
The interior angles of a triangle sum to 180°, therefore the other two angles are complementary angles since their sum is always 90°.
So we can label one angle as [tex]x[/tex] and the other as [tex](90-x)[/tex].
The side opposite angle [tex]x[/tex] is the side adjacent to angle [tex](90-x)[/tex].
Therefore, using trig ratios, we can say that [tex]\sin(x) = \cos(90-x)[/tex]
So, if [tex]x=44[/tex] then:
[tex]\implies \sin(44) = \cos(90-44)=\cos(46)[/tex]
If the labor force is 300,000 workers,
but 24,000 are unemployed, what is the
unemployment percentage?
A. 3%
B. 8%
C. 18%
D. 24%
Answer:
8%
Step-by step explanation:
We are given:
Total workers: 300,000Unemployed workers: 24,000The formula to determine the percentage of unemployed workers in the total workers, we need to divide the number of unemployed works by the total workers in the labor force. Then, multiply the quotient by 100 to obtain the percentage of unemployed workers.
Formula:
[tex]\dfrac{\text{Unemployed workers}}{\text{Total workers} } \times 100 = \text{Percentage of unemployed workers}[/tex]
Substitute the given values into the formula to determine the percentage of unemployed workers in the labor force.
[tex]\implies \dfrac{\text{24,000}}{\text{300,000} } \times 100 = \text{Percentage of unemployed workers}[/tex]
Now, simplify the equation. The easiest way to simplify the equation is to temporially ignore the "100".
[tex]\implies \dfrac{\text{24,000}}{\text{300,000} } = \text{Percentage of unemployed workers}[/tex]
Then, cancel the "0's" on the L.H.S. This is a good way to simplify the equation on the L.H.S
[tex]\implies \dfrac{\text{24}}{\text{300} } = \text{Percentage of unemployed workers}[/tex]
Don't forget to multiply the result by 100 as it was temporaily hidden.
[tex]\implies \dfrac{\text{24}}{\text{300} } \times 100= \text{Percentage of unemployed workers}[/tex]
Let 100 be 100/1. Thus, our equation will be:
[tex]\implies \dfrac{\text{24}}{\text{300} } \times \dfrac{100}{1} = \text{Percentage of unemployed workers}[/tex]
Multiply the numerator with the numerator and the denominator with the denominator.
[tex]\implies \dfrac{24 \times 100}{\text{300} \times 1} } = \text{Percentage of unemployed workers}[/tex]
[tex]\implies \dfrac{2400}{\text{300} } = \text{Percentage of unemployed workers}[/tex]
Cancel the "0's" on the L.H.S to make it easier to simplify.
[tex]\implies \dfrac{2400}{\text{300} } = \text{Percentage of unemployed workers}[/tex]
[tex]\implies \dfrac{24}{\text{3} } = \text{Percentage of unemployed workers}[/tex]
[tex]\implies 8 = \text{Percentage of unemployed workers}[/tex]
Thus, 8% of the workers are unemployed workers.

reaches an electric box 31 feet up. The ladder makes an angle of 78° with the ground.
Find the length of the ladder. Round your answer to the nearest tenth of a foot if
a
necessary.
Answer:
50.41 feet
Step-by-step explanation:
Hypotenuse = length of ladder
31 = opposite side of angle
sin(angle) = (opposite)/(hypotenuse)
sin(78) = (36)/(hypotenuse)
hypotenuse = sin(78)/ (36)
hypotenuse = 50.41 feet
length of ladder = 50.41 feet
Randy has 1.5 gallons of sprite and 2.25 gallons of coke in his fridge. Andy has 1.15 gallons of sprite and 0.62 gallons of coke. How much more soda does Randy have than Andy?
Answer:
1.98Gal
Step-by-step explanation:
Randy soda total is 1.5 gal + 2.25 Gal = 3.75 Gal
Andy soda total is 1.15 + 0.62 Gal = 1.77 Gal
3.75-1.77=1.98Gal
1.98
Step-by-step explanation:
1.5+2.25=3.75
1.15+0.62=1.77
3.75-1.77=1.98

Answer:
26
Step-by-step explanation:
simply count the number of times the team scored more than 50 points by looking at the graph.
the team scored 51-60 points 11 times, 61-70 points 12 times and 71-80 points 3 times.
so the team scored more than 5 points a total of 11 + 12 + 3 = 26 times
Answer:
26
Step-by-step explanation:
Game scores above 50 points can be represented by the last three boxes to the left. To find the total number of times this happened, add up the values measured by the y-axis:
51-60 = 11 games
61-70 = 12 games
71-80 = 3 games
11 + 12 + 3 = 26

if the length of diagonal of a square is 4√2 cm, find it's length, perimeter and area.
Answer:
As Per Provided Information
Length of diagonal of square is 4√2 cmWe have been asked to find the length , perimeter and area of square .
First let's calculate the side of square .
Using Formulae
[tex] \boxed{\bf \:Diagonal_{(Square)} \: = side \sqrt{2}}[/tex]
On substituting the value in above formula we obtain
[tex] \qquad\longrightarrow\sf \:4 \sqrt{2} = side \sqrt{2} \\ \\ \\ \qquad\longrightarrow\sf \:4 \cancel{\sqrt{2}} = side \cancel{ \sqrt{2}} \\ \\ \\ \qquad\longrightarrow\sf \:side \: = 4 \: cm[/tex]
Therefore,
Length of its side is 4 cm.Finding the perimeter of square.
[tex] \boxed{\bf \: Perimeter_{(Square)} = 4 \times side}[/tex]
Substituting the value we obtain
[tex]\qquad\longrightarrow\sf \:Perimeter_{(Square)} \: = 4 \times 4 \\ \\ \\ \qquad\longrightarrow\sf \:Perimeter_{(Square)} = 16 \: cm[/tex]
Therefore,
Perimeter of square is 16 cm .Finding the area of square .
[tex] \boxed{\bf \: Area_{(Square)} = {side}^{2}}[/tex]
Substituting the value we get
[tex]\qquad\longrightarrow\sf \:Area_{(Square)} \: = {4}^{2} \\ \\ \\ \qquad\longrightarrow\sf \:Area_{(Square)} = 16 \: {cm}^{2} [/tex]
Therefore,
Area of square is 16 cm².Calculate the rise and run to and the slope of each line. someone help me
Rise: -4
Run: 3
Solution:The rise is how many units we move up or down.The run is how many units we move left or right.We move down 4 units, so the rise is -4.Then, we "run" 3 units, so the run is 3.Hope it helps.

there are 36 pupils in a class.the number of boys is twice the number of girls.how many are girls?
Answer:
12 girls
Step-by-step explanation:
Boys to girls ratio= 1:2
Thats means there are (1+2) 3 total parts.
So [tex]\frac{36}{3}[/tex]=12
Each part is 12 so
boys is 12*2= 24 boys
Girls id 12*1= 12 girls
Answer:
12
Step-by-step explanation:
Total number of students in class ⇒ 36
Given that,
The number of boys is twice the number of girls.
First, let us make an expression to find the number of girls.
For that, let the number of girls be x.
Number of girls ⇒ x
Number of boys ⇒ 2x
Total number of pupils ⇒ x + 2x
So,
x + 2x = 36
3x = 36
Divide both sides by 3.
x = 12
Therefore, there are 12 girls and 24 boys in the class.

Answer: [tex]A=539\pi /16=105.8m^2[/tex]
Step-by-step explanation:
Think of the white circle being on top of a larger shaded circle. You were given the diameter of this larger shaded circle. And, you were also secretly given the diameter of the inner white circle. If you find the area of the white circle, and subtract it from the area of the shaded circle, you will find the area of the shaded region.
Beginning with the area of the shaded circle. The diamater is 21 meters, while the radius is 21/2 meters. Therefore, the area is:
[tex]A=\pi r^2[/tex]
[tex]A=\pi (21/2)^2[/tex]
[tex]A=441\pi /4[/tex]
Moving on to the white circle. The diameter would be 21 meters with 3.5 meters subtracted from it:
[tex]d=21-3.5=17.5=35/2[/tex]
Therefore the radius is:
[tex]r=(35/2)/2=35/4[/tex]
Which means the area would be:
[tex]A=\pi r^2[/tex]
[tex]A=\pi (35/4)^2[/tex]
[tex]A=1225\pi /16[/tex]
Therefore the shaded region is:
[tex]A=441\pi /4-1225\pi /16[/tex]
Get common denominators:
[tex]A=1764\pi /16-1225\pi /16[/tex]
[tex]A=539\pi /16[/tex]
