Answer:
x = 2
Step-by-step explanation:
f(x) = x + 8
f(x) = 10
10 = x + 8
minus 8 from the both sides
10 - 8 = x
2 = x
x = 2
Janet and Nadia each play basketball Nadia has won twice the number of games Janet has is it possible for Janet to have 110 games if the sum of the games naughty and Janet have one together is 24
Answer: d. No; Janet could not have won 10 games because 3x ≠ 24.
Step-by-step explanation:
Assume the number of games won by Janet is x. This would mean that the number of games won by Nadia is 2x.
The total number of games played by both would therefore be;
x + 2x = 3x
Janet has won 10 games and we need to find out if the total number of games can be 24 if this is the case.
Expression would therefore be;
3x = 24
x = 10 so;
3(10) ≠ 24
There is therefore no way that they could have played 24 games if Janet had won 10 games. They would have to have played 30 games.
A car’s wheels spin at 1000 revolutions per minute. The diameter of the wheels is 23 inches. You want to know how fast the car is travelling.
A:Circumference
B:Area
Answer:
Speed = 72,285 in/min
Step-by-step explanation:
Given:
Total revolution per min = 1,000
Diameter = 23 in
Radius = 23/2 in
Time = 1 min
Find:
Speed
Computation:
Total distance = 2πr(1000)
Speed = Distance / time
Speed = 2πr(1000) / 1
Speed = 2π(23/2)(1000) / 1
Speed = 72,285 in/min
Slope = 1, y-intercept = -2
please show work
Answer:
The slope intercept form would be y=x-2
Step-by-step explanation:
The slope intercept form is y=mx+b. In this case, y and x are undefined, so you keep them as variables.
The variable m stands for the slope, and you multiply it with x. Since it is 1, and one times anything keeps the number the same, you can keep the 1 out. now we have y=x+b.
The y-intercept us -2, so we replace that with b. y=x+(-2). Since adding a negative is the same as subtracting, we can change the operation.
So, you end up with y=x-2.

In AABC, mZA (3x + 1)º, m B = (x + 14)", and mZC = (4x + 5)º. What is the value of x?
Answer:
x = 20
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
3x + 1 + x + 14 + 4x + 5 = 180, that is
8x + 20 = 180 ( subtract 20 from both sides )
8x = 160 ( divide both sides by 8 )
x = 20

A tunnel has a semicircular cross-section
and a diameter of 10 m. If the roof of a bus
just touches the roof of the tunnel when
the bus is 2 m from one side, how high is
the bus?
Answer:
You should be able to solve this easily just by drawing the tunnel and the bus (you may use 1cm for 1m). Notice how the bottom of the tunnel, the side of the bus, and a radius of the tunnel form a right-angled triangle. All you need to do is to find the sides of the triangle.
A speed skater completers a 500-meter race in 40 seconds. A cheetah runs 260 meters in 10 seconds. How do their speeds compair? Find the number of meters a speed skater and a cheetah travel in one second.
A speed skater travels ___ meters per second.
A cheetah travels ___ meters per second.
Answer:
A speed skater travels 12.5 meters per second
A cheetah travels 26 meters per second
Step-by-step explanation:
To find their speeds, divide the number of meters by the number of seconds:
Speed skater:
500/40
= 12.5 meters per second
Cheetah:
260/10
= 26 meters per second
So, a speed skater travels 12.5 meters per second and a cheetah travels 26 meters per second.

In mike's state, the weekly unemployment compensation is 45% of the 26 weekly for the two highest salaried quarters. A quarter is three consecutive months. For july,august, and september, mike earned a total of $22,500. In october, november, and december, he earned a total of $22,900. Determine Mike's weekly unemployment compensation .
Answer:
$785.77
Step-by-step explanation:
Assuming that Mike earned the highest compensation between July and December (third and fourth quarters), his total compensation for the six month period = $22,500 + $22,900 = $45,400
his average weekly salary = $45,400 / 26 weeks = $1,746.15
Mike's unemployment compensation = $1,746.15 x 45% = $785.77

the cube root of 1 + cube root of 343 equals to what ??
Answer:
I hope this may help
Step-by-step explanation:
Clearly, 343 is a perfect cube. Therefore, group the factors of 343 in a pair of three and write in the form of cubes. Step 3: Now, we will apply cube root to both the sides of the above expression to take out the term in cubes.

The 4th term of a sequence is 108. Each term after the first is three times the previous term. Write an expression that represents all 4 terms. Write an equation that represents the 4th term. What are the 4 numbers?
Answer:
First 4 terms are a, 3a, 3^2 a and 3^3 a.
The numbers are:
4, 12, 36, 108.
Step-by-step explanation:
This is a geometric sequence and we can write it as:
a, ar, ar^2, ar^3 <---- the first 4 terms.
Here the common ratio r = 3 and the 4th term is 108 so:
a(3)^3 = 108
So the first term a = 108 / 3^3
= 108/27
= 4.
So the second number = 3*4 = 12 and 3rd is 12*3 = 36.
6 There are 10 lanes in the bowling alley where Harold bowls. He wants to make a
scale drawing of the bowling alley using a scale of 3 cm to 15 ft. One lane,
including gutters, is 60 ft long and 5 ft wide. What will the width of all 10 lanes on
his drawing be?
Answer:
The width of 10 lanes would be a total of 10 centimeters , 1 cm for each lane on his drawing.
Step-by-step explanation:
The scale he uses is
15 ft= 3 cm
1 feet = 3/15 cm
1 cm= 15ft/3= 5 ft
One lane = 60 ft long and 5 ft wide
In centimeters it would be 60 ft / 5ft = 12 cm long and 5 ft/5ft= 1 cm wide
The width of 1 lane is 1 cm .
The width of 10 lanes would be a total of 10 centimeters , 1 cm for each lane on his drawing.

Answer:
16π = 50.27
Step-by-step explanation:
First lets find the area of both triangles
A = πr²
Smaller Area:
A = πr²
A = π 3²
A = π9
A = 9π
Larger Area:
A = πr²
A = π(5)²
A = π25
A = 25π
Now subtract the smaller from the larger to get the shaded left over
25π - 9π = 16π

b) Solve x²+5x + 6 = 0
Answer:
x = 2, x = 3
Step-by-step explanation:
Factorization by splitting middle term.
Hope this helped!
Answer:
x = - 3
x = - 2
Step-by-step explanation:
x² + 5x + 6 = 0
x² + 2x + 3x + 6 = 0
x(x + 2) + 3(x + 2) = 0
(x + 3) (x + 2) = 0
x + 3 = 0 or x + 2 = 0
x = - 3 or x = - 2
