Answer:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends
Step-by-step explanation:
Given
[tex]Weekdays = \$m /hour[/tex]
[tex]Weekends = \$1.2m/hour[/tex]
Required
What does 9m + 3(1.2m) represent
The expression can be split to:
9m and 3(1.2m)
For 9m:
From the question, we understand that:
[tex]m = 1\ hour[/tex]
Multiply both sides by 9
[tex]9 * m = 1\ hour * 9[/tex]
[tex]9 m = 9\ hours[/tex]
This means that:
9m = the cost of lessons for 9 hours on weekdays
For 3(1.2m):
From the question, we understand that:
[tex]1.2m = 1 \ hour[/tex]
Multiply both sides by 3
[tex]3 * 1.2m = 1 \ hour * 3[/tex]
[tex]3(1.2m) = 3 \ hours[/tex]
This means that:
3(1.2m) = the cost of lessons for 3 hours on weekends
Hence, the expression represents:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends

Answer:
try 4 inches
Step-by-step explanation:
since the diameter is 8 inches, then we can do 82 to find the radius, or 4 inches.
. Solve; 2x+96=182 hurry due in 5 mins
Move all terms that don't contain x to the right side and solve.
x = 43
Answer:
x=43
Step-by-step explanation:
2x+96=182
2x=86 (Subtract 96 from 182)
x=43 (Divide 86 by 2)
Find the next three terms.

The number of fish in a lake decreased by 25% between last year and this year. This year there are 45 fish in the lake. What was the population of last year
Answer:
The population of last year was 60.
Step-by-step explanation:
From the information given, as you know that the number of fish in a lake decreased by 25% between last year and this year, the amount of fish this year represents 75% of last year's population as: 100%-25%=75%. With that, you can use a rule of three to find last year's population tha would represent 100% given that 75% is equal to 45 fish.
75% → 45
100% → x
x=(100*45)/75= 60
According to this, the answer is that the population of last year was 60.

finding side length of the 90-degree angle triangle
Answer:
x = 4
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex]
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
[tex]\sqrt{2}[/tex] x = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )
x = 4

Brittney attempted to order a set of numbers from least to greatest
-2.9 72/80 2.979 3 1/5 π
what does Brittney need to do to make the order correct?
She needs to convert all the numbers be be the same type ( fraction or decimal).
With the numbers she has it would be easiest to convert all the numbers to decimals.
72/80 = 0.9
3 1/5 = 3.3
Pi = 3.14
Now she can arrange the decimals in order:
-2.9, 0.9, 2.979, 3.14, 3.2
She needs to switch 3 1/5 and pi
Answer:
3 1/5 is tha one

The original price of a CD is 9.95 tax is 4% what the answer
Answer:
$9.55
Step-by-step explanation:
4/100=0.04
0.04x9.95=0.40
9.95-0.40=9.55
4% of 9.95 is 0.398, so you would add about $0.40 to the original amout.

A light-year is the distance light travels in one year, about 5.9×1012 mi. Earth is located about 25,000 light-years from the Milky Way's rim. What is the approximate distance, in miles, from Earth to the rim of the Milky Way?
Answer:
1.475 × 10¹⁴ mi
Step-by-step explanation:
Since 1 light year = 5.9 × 10⁹ mi and the Earth is located about 25,000 light-years from the Milky Way's rim, the approximate distance, in miles, from Earth to the rim of the Milky Way is 25,000 light year = 25,000 × 1 light year
= 25,000 × 5.9 × 10⁹ mi
= 147.5 × 10¹² mi
= 1.475 × 10¹⁴ mi

Answer:
The inequality describes all possible value of x is 14 < x < 32 ⇒ D
Step-by-step explanation:
In any triangle:
The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sidesIn the given figure
∵ ABC is a triangle
∵ AC = 9 and BC = 21
∵ AB is the third side of the triangle
→ By using the rules above
∴ BC - AC < AB < BC + AC
∵ AB = x - 2
→ Substitute their values in the inequality above
∵ 21 - 9 < x - 2 < 21 + 9
∴ 12 < x - 2 < 30
→ Add 2 to the 3 terms
∴ 12 + 2 < x - 2 + 2 < 30 + 2
∴ 14 < x < 32
∴ The inequality describes all possible value of x is 14 < x < 32

Ap ex: What is the solution to this system of equation?
y = x - 4 y = -0.5x + 8
a. (4,2)
b. (8,4)
c. (4,8)
d. (2,4)
Answer:
x = 8, y = 4
Step-by-step explanation:
y = x - 4
y = -0.5x + 8
y = y
x - 4 = -0.5x + 8
x + 0.5x = 8 + 4
1.5x = 12
x = 12/1.5
x = 8
To get "y" substitute the 8 for the "x" value in any of the two equations (they will both give the same answer.)
y = (8) - 4
y = 4
OR
y = -0.5(8) + 8
y = -4 + 8
y = 4

An aeroplane takes off and flies steadily for a distance of 5.6 km at an altitude of 2 km from it's runway . Calculate the angle that it makes with the horizontal
Answer:
The angle the aero plane makes with the horizontal is approximately 20.925°
Step-by-step explanation:
The given parameters are;
The distance the aero plane flies = 5.6 km
The elevation to which the aero plane flies = 2 km
The angle the path of the aero plane as it takes off makes with the horizontal, θ, is the angle opposite the altitude of the right triangle formed by the aero plane's path (the hypotenuse), the horizontal, and the line drawn from the final position of the aero plane, representing the altitude (the opposite leg to angle θ)
By the trigonometric ratio for the sin of the angle, θ, we have;
[tex]sin(\theta) = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length} = \dfrac{2 \ km}{5.6 \ km} = \dfrac{2}{5.6}[/tex]
Therefore, the angle θ the aero plane makes with the horizontal is given as follows;
[tex]\theta = arcsin \left (\dfrac{2}{5.6} \right ) \approx 20.925 ^{\circ}[/tex]
The angle the aero plane makes with the horizontal ≈ 20.925°.
