15 more than ten times a number equals 60. What is the number?
Answer:
4.5
Step-by-step explanation:
Let the number be x, then:
10x + 15 = 6010x = 60 - 1510x = 45x = 45/10x = 4.5The number is 4.5
Answer:
4.5
Step-by-step explanation:
let the number be x , then
10x + 15 = 60 ( subtract 15 from both sides )
10x = 45 ( divide both sides by 10 )
x = 4.5
The number is 4.5
Making a round trip from Fairview to Cartersville, a distance of 20 miles, a pilot faces 30 mph head wind one way and 30 mph tail wind on the return trip. The return trip takes 45 minutes less than the outbound journey. Find the speed of the plane in still air
Answer:
50mph
Step-by-step explanation:
Given the following :
Distance (d) of journey = 20 miles
Wind speed = 30mph head wind in one way, 30mph tail wind in the other direction
Return trip = 45 minutes (45/60 = 0.75 hour) less Than the outbound journey
Speed of plane in still air
Outbound trip :
Velocity = Distance / time
Time = distance / velocity
Velocity = (v - 30) due to head wind
Return Velocity (V +30) due to tail wind
Outbound time = return distance
20 / (v - 30) = 20 / (v +30) + 0.75
20v + 600 = 20v + 0.75v^2 + 22.5v - 600-22.5v-675
600 = 0.75v^2 - 1275
0.75v^2 = 1875
v^2 = 1875/ 0.75
v^2 = 2500
v = sqrt(2500)
v = 50mph

during a basketball game, your team scored three times as many 2-point field goals than it did 3-point field goals, and scored a total of 90 points. How many field goals did your team score? (there were no 1-point free throws)
Answer:
Ok, let's define the notation:
A is the number of 2-point field goals that your team scored.
B is the number of 3-point field goals that your team scored:
We know that:
" your team scored three times as many 2-point field goals than it did 3-point field goals,"
This can be written as:
A = 3*B
" And scored a total of 90 points."
A*2 + B*3 = 90
Then we have a system of two equations and two variables:
A = 3*B
A*2 + B*3 = 90
Now we can replace the first equation into the second one and get:
(3*B)*2 + B*3 = 90
B*6 + B*3 = 90
B*9 = 90
B = 90/9 = 10
And we know that:
A = 3*B
A = 3*10 = 30
Then your team scored 30 2-point field goals and 10 3-point field goals (a total of 40 if you combine them)

What is 2/3 divided by 6/5
please help –8 = c /9 c=
Hey there! I'm happy to help!
We want to get c all by itself on one side of the equation. Usually variables go on the left side, so let's flip the equation around.
c/9=-8
If we multiply c/9 by 9, the 9 will cancel out because if you divide by 9 and then multiply by 9 it just equals 1. We can do this to isolate the c, but whatever you do to one side of the equation, you have to do to the other. So, we multiply both sides by 9.
c/9×9=-8×9
c=-72
Have a wonderful day! :D
Answer:
c = -72
Step-by-step explanation:
Multiply each side by 9, so it now looks like this: -72 = cI hope this helps!
A friut stand sells watermelons during the summer. The revenue for selling x watermelons is given by f(x)=2.5x. The team's profit is $25 more than 60% of the revenue for selling x watermelons. Write a funcction g to model the profit. Then find the profit for selling 44 watermelons.
Answer:
$91
Step-by-step explanation:
f(x) = 2.5 x
$25 more would + $25 to the function
60% = .6
Revenue is f(x) = 2.5x which we have to multiply by the .6
g(x) = $25 + .6 (2.5 x)
If we have 44 watermelons then we plug in 44 for x
x = 44
g(x) = $25 + .6 (2.5*44)
g(x) = $25 + .6 (110)
g(x) = 25 + 66
g(x) = $91
The profit is $91
Brown Squirrels can carry 2 acorns at a time. Gray Squirrels can carry 3 acorns at a time. Black Squirrels can carry 5 acorns at a time. Suppose the three squirrels all wanted to store acorns for the winter. Depending on how motivated each squirrel was they would end up with different amounts. For instance, suppose the Brown Squirrel took 4 trips, the Gray Squirrel took 2 trips and the Black Squirrel took 2 trips. The Brown Squirrel would end up with 8 acorns, the Gray Squirrel would have 6 acorns and the Black Squirrel would have 10 . Between them they took every one of the 24 acorns. How Many Ways "Show Them" can the squirrels get all 24 acorns. (One can get all of them, and the others get none
Answer:
There are five ways in which the squirrels can get all 24 acorns.
Step-by-step explanation:
The information provided is:
Brown Squirrels can carry 2 acorns at a time.Gray Squirrels can carry 3 acorns at a time. Black Squirrels can carry 5 acorns at a time. The three squirrels all wanted to store acorns for the winter. Between them they took every one of the 24 acorns.Each squirrel makes at least one trip.
Consider the table for the total number of trips the squirrels make get all 24 acorns:
Brown (2) Gray (3) Black (5) Total no. of acorns
1 4 2 (1 × 2) + (4 × 3) + (2 × 5) = 24
2 5 1 (2 × 2) + (5 × 3) + (1 × 5) = 24
3 1 3 (3 × 2) + (1 × 3) + (3 × 5) = 24
4 2 2 (4 × 2) + (2 × 3) + (2 × 5) = 24
5 3 1 (5 × 2) + (3 × 3) + (1 × 5) = 24
Thus, there are five ways in which the squirrels can get all 24 acorns.

is 14 times 10 to the power of 8 in scientific notation?
Answer: NO
Step-by-step explanation:
14 × 10^8 is not in scientific notation
scientific notation: a×10^b, where should be 0<a<10
As seen above, 14 is greater than 0, but also greater than 10, thus, it is not in scientific notation.
------------------
EXTRA: How to change it into proper scientific notation
To change it into scientific notation, we need to divide 14 by 10, do get 1.4. (or just move the decimal point to the left by 1 unit)
1.4 is within the range of 0-10.
1.4 × 10^9 (remember, we just divided 14 by 10, and so we need to add on the exponent by 1)

Find the greatest common factor (GCF)
if a cone and a cylinder have the same radius and the perpendicular height of the cone is twice that of a cylinder find the ratio of the volume
Answer:
2/3
Step-by-step explanation:
h = height of the cone
Vcone = πr²h/3
H = h/2 = height of the cylinder
Vcylinder = πr²H = πr²h/2
Vcone/Vcylinder = (πr²h/3)/(πr²h/2)
= πr²h/3 x 2/πr²h
= 2/3
Answer:
2/3
Step-by-step explanation:
h = height of the cone
Vcone = πr²h/3
H = h/2 = height of the cylinder
Vcylinder = πr²H = πr²h/2
Vcone/Vcylinder = (πr²h/3)/(πr²h/2)
= πr²h/3 x 2/πr²h
= 2/3
What are the 2 inequality?
Write the domain as an inequality

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to
the nearest tenths place.
13
8
Answer:
Total area of the composite figure = 129.1 square units
Step-by-step explanation:
Area of the figure attached = Area of semicircle + Area of the rectangle
Since area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
where 'r' = radius of the circle
Area of the semicircle = [tex]\frac{1}{2}\pi (4)^{2}[/tex]
= 8π
= 25.1 square units
Area of the rectangle = Length × width
= 13 × 8
= 104 square units
Total area of the composite figure = 25.1 + 104
= 129.1 square units

A cyclist rides his bike at a rate of 15 miles per hour. what is this rate in miles per minute? how many miles will the cyclist travel in 20 minutes? do not round your answers.
Answer:
15 miles/hour = 0.25 miles/minute
The cyclist would have traveled 5 miles in 20 minutes.
Step-by-step explanation:
15 miles per hour is written as
15 miles/hour
To convert 15 miles/hour to miles/minute
From 1 hour = 60 minutes
∴ 15 miles/hour = 15 miles/ 60 minutes
= (15/60) miles/minute
= 0.25 miles/minute
To calculate how many miles the cyclist will travel in 20 minutes
That is, Time, t = 20 minutes
Velocity, v = 15 miles/hour = 0.25 miles/minute
Distance, s = ??
From,
[tex]Velocity = \frac{Distance}{Time}\\[/tex]
∴[tex]Distance = Velocity[/tex] × [tex]Time[/tex]
[tex]Distance = 0.25 miles/minute[/tex] × [tex]20 minutes[/tex]
[tex]Distance = 5 miles[/tex]
Hence, The cyclist would have traveled 5 miles in 20 minutes.

Should be simple geometry but I’m brainless
x = 6 and KL = 32
First off, you're not brainless, your brain needs practice that's all.
Since L is the midpoint of the line KM, that means KL = LM
KL [tex]= 5x + 2[/tex]
LM [tex]= 9x - 22[/tex]
KL = LM
[tex]5x+2=9x-22\\5x=9x-24\\-4x=-24\\x=\frac{-24}{-4} \\x=6[/tex]
KL [tex]= 5x + 2[/tex], substitute [tex]x[/tex]:
KL [tex]=5(6)+2[/tex]
KL [tex]= 30 + 2[/tex]
KL [tex]= 32[/tex]
let's also find LM just for fun
LM [tex]= 9x-22[/tex], substitute [tex]x[/tex] again:
LM [tex]= 9(6) -22[/tex]
LM [tex]=54-22[/tex]
LM [tex]=32[/tex]
this proves that KL = LM
