Answer:
x = 60
Step-by-step explanation:
The formula for this kind of question is
Area of sector = x / 360 * pi * r^2 = 24*pi
x/360 * pi * 12^2 = 24 pi
x/360 * pi * 144 = 24 pi the pi s cancel out
x / 360 = 24/144 Multiply both sides by 360
x = 24 * 360/144
x = 60

Help pls!! Find the value of x and m
Answer:
The answer's the third one listed.
Step-by-step explanation:
The equation to solve for x is:
6x + 16 + 10x - 6 + 90 = 180
16x + 100 = 180
16x = 80
x = 5
To solve for angle BCD, just substitute 5 for x
m = 10(5) - 6
m = 50 - 6
m = 44

Step-by-step explanation:
[tex]3\frac{1}{5} \times 2\frac{1}{5}[/tex]
Lets convert it into improper fraction.
[tex]\frac{16}{5} \times \frac{11}{5} = \frac{16 \times 11}{5 \times 5} = \frac{176}{25}[/tex]
Lets convert [tex]\frac{176}{25}[/tex] into a mixed fraction.
[tex]=> \frac{176}{25} = 7\frac{1}{25} = 7.04[/tex]
Rounding off 7.04 gives 7 and rounding 7 further gives 10.
So , the estimate of the product is 10

Answer:
1) 0.9 as fraction is: [tex]\mathbf{\frac{9}{10}}[/tex]
2) Solve for c =4 for the equation [tex]2 \times (c^2-5)[/tex] we get 22
3) t = 64
4) p=3.15
5) Volume of Cuboid = 160 m³
6) x =9
Step-by-step explanation:
1) Write as fraction: 0.9
For writing the fraction, Since we have decimal point at tent's place so we can write it as: [tex]\frac{9}{10}[/tex]
So, 0.9 as fraction is: [tex]\mathbf{\frac{9}{10}}[/tex]
2) Solve for c =4
[tex]2 \times (c^2-5)[/tex]
Put c = 4 and find the answer
[tex]2 \times (c^2-5)\\Put\:c=4\\=2\times ((4)^2-5)\\=2\times (16-5)\\=2\times(11)\\=22[/tex]
So, Solve for c =4 for the equation [tex]2 \times (c^2-5)[/tex] we get 22
3) [tex]\frac{t}{4}=16[/tex]
We need to find value of t
Multiply both sides by 4
[tex]4\times\frac{t}{4}=16\times 4\\t=64[/tex]
So, we get t = 64
4) [tex]2.4p=7.56[/tex]
We need to find value of p
Divide both sides by 2.4
[tex]\frac{2.4p}{2.4}=\frac{7.56}{2.4}\\p=3.15[/tex]
So, we get p=3.15
5) Find Volume of Cuboid
The formula used is: [tex]Volume\:of\: Cuboid=Length\times Breadth \times Height[/tex]
We have Length = 4, Breadth = 8 and Height = 5
Putting values and finding volume:
[tex]Volume\:of\: Cuboid=Length\times Breadth \times Height\\Volume\:of\: Cuboid=4\times 8 \times 5\\Volume\:of\: Cuboid=160[/tex]
So, Volume of Cuboid = 160 m³
6) [tex]3x=27[/tex]
We need to find value of x
Divide both sides by 3
[tex]3x=27\\\frac{3x}{3}=\frac{27}{3}\\x=9[/tex]
We get x =9

Flying against the wind , an airplane travels 3660 kilometers in 6 hours. flying with the wind , the same plane travels 3800 kilometers in 4 hours. what is the rate of the plane in still air and what is the rate of the wind?
Answer:
...
against the wind, an airplane travels 3640 km in 7 hours.
with the wind, the same plane travels 6000 km in 6hrs.
...
let speed of plane in still air be x mph
speed of wind be y mph.
..
t=d/r
..
against wind speed = x-y mph
with wond speed = x=y mph
...
3640/(x-y)=7
3640 = 7x-7y
/7
520=x-y.....................1
...
6000/x+y = 6
6000 = 6x+6y
/6
1000=x+y.....................2
...
Add (1) & (2)
2x=1520
/2
x=760 mph speed of plane in still air
...
plug value of x in 2
1000=760+y
100-760=y
240 = y
240 mph speed of wind

What is the slope of the line 6x + y = 24?
Answer:
-6
Step-by-step explanation:
You need to get it in Point-Slope form, or
y = mx + b
Isolate y by subtracting 6x
You are left with:
y = -6x + 24
M is the slope, so in this case, it is -6
Answer:
The slope is -6/1 but the slope-intercept form is y=-6x+24
Step-by-step explanation:
y=mx+b
6x+y=24
first you want to subtract 6x from each side.
y=-6x+24
m=-6x or -6/1
b= 24

Suppose that 8 machines can complete a certain task in 9 days. if there are 18 machines, how many days would it take for them to finish the same task?
Answer:
It would require 4 days.
If there are 18 machines. Then the number of days would it take for them to finish the same task will be 4 days.
What is Algebra?Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
Time is inversely proportional to the number of the machines.
T ∝ 1/M
If the proportionality is removed, then a constant k is introduced.
Suppose that 8 machines can complete a certain task in 9 days.
Then the amount of the total work that is k will be
k = 8 x 9
k = 72
If there are 18 machines.
Then the number of days would it take for them to finish the same task will be
T = 72 / 18
T = 4 days
The number of days would it take for them to finish the same task will be 4 days.

Solve the system of linear equations by elimination.
-3.x – 5y = -7
-4x + 5y = 14
Answer:
(- 1, 2 )
Step-by-step explanation:
Given the 2 equations
- 3x - 5y = - 7 → (1)
- 4x + 5y = 14 → (2)
Add the 2 equations term by term to eliminate y , that is
- 7x + 0 = 7
- 7x = 7 ( divide both sides by - 7 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
- 3(- 1) - 5y = - 7
3 - 5y = - 7 ( subtract 3 from both sides )
- 5y = - 10 ( divide both sides by - 5 )
y = 2
solution is (- 1, 2 )
Answer:
( -1, 2)
Step-by-step explanation:
Since this is asking for elimination, you will need to line up x or y to be the opposite amount:
-3x -5y = -7
-4x + 5y = 14
(notice -5y and 5y are already opposite, therefore no further actions are needed to line them up.)
Next step is to add both equations up to eliminate y and to find x:
-7x = 7
x = -1
After finding x, plug the x back into either one of the equations to solve for y. If you are unsure, you can plug it into the other equations to double check.
If you chose to do equation 1:
-3(-1) -5y = -7
3 -5y = -7
-5y = -10
y = 2
If you chose to do equation 2:
-4(-1) + 5y = 14
4 + 5y = 14
5y = 10
y = 2
After finding x and y, you will find the point ( -1, 2)
