Answer:
3.58
Step-by-step explanation:
what angle does an arc 6.6cm on length subtends at the centre of a circle of radius 14cm? take
[tex]\pi = 22 \7[/tex]
Given:
Arc length = 6.6 cm
Radius = 14 cm
To find:
The angle subtended by the arc at the center.
Solution:
The formula for arc length is:
[tex]s=2\pi r\dfrac{\theta}{360}[/tex]
Where, s is the arc length, r is the radius and [tex]\theta[/tex] is the central angle in degrees.
Putting [tex]s=6.6,\pi=\dfrac{22}{7},r=14[/tex],we get
[tex]6.6=2\times \dfrac{22}{7}\times 14\times \dfrac{\theta}{360}[/tex]
[tex]6.6=88\times \dfrac{\theta}{360}[/tex]
[tex]\dfrac{6.6}{88}\times 360=\theta[/tex]
[tex]27^\circ=\theta[/tex]
Therefore, the measure of the central angle is [tex]27^\circ[/tex].

prove that √p is an irrational number , if p is not a perfect square.
[tex] \huge \frak \green{question}[/tex]
prove that √p is an irrational number , if p is not a perfect square.
[tex] \huge \frak \red{answer}[/tex]
Let us assume, to the contrary, that √p is rational. So, we can find coprime integers a and b(b ≠ 0) such that :-
=> √p = a/b
=> √p b = a
=> pb² = a² ….(i) [Squaring both the sides]
=> a² is divisible by p
=> a is divisible by p So, we can write a = pc for some integer c.
Therefore,
a² = p²c² ….[Squaring both the sides]
=> pb² = p²c² ….[From (i)]
=> b² = pc²
=> b² is divisible by p
=> b is divisible by p
=> p divides both a and b.
=> a and b have at least p as a common factor.
But this contradicts the fact that a and b are coprime. This contradiction arises because we have assumed that √p is rational. Therefore, √p is irrational.

Oliver drove 278 miles in 4 hours how much hours does it take him to drive 139 miles
PLSSS HELP
Answer:
34.75 i think
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 2 \ hours}}[/tex]
Step-by-step explanation:
Let's set up a proportion to solve. Use the following setup:
[tex]\frac {hours}{miles}=\frac{hours}{miles}[/tex]
We know that it takes Oliver 4 hours to drive 278 miles.
[tex]\frac {4 \ hours}{278 \ miles}=\frac{hours}{miles}[/tex]
We don't know how long it takes him to drive 139 miles. Therefore, we use the variable x for hours, because it is unknown.
[tex]\frac {4 \ hours}{278 \ miles}=\frac{x \ hours}{139 \ miles}[/tex]
[tex]\frac {4 }{278 }=\frac{x \ hours}{139 }[/tex]
We are solving for x, the hours it takes him to drive 139 miles. The variable must be isolated. It is being divided by 139 and the inverse of division is multiplication. Multiply both sides of the equation by 139.
[tex]139*\frac {4 }{278 }=\frac{x \ hours}{139 }*139[/tex]
[tex]139*\frac {4 }{278 }={x }[/tex]
[tex]2=x[/tex]
It takes Oliver 2 hours to drive 139 miles.

A rectangular piece of fabric was used to make a banner. It measured 12 feet long and had an area of 24 square feet. What is its perimeter?
Answer:
the perimeter is 28
Step-by-step explanation:
2+2=4
12+12=24
24+4=28
Answer:
Perimeter = 28 feet
Step-by-step explanation:
The formula to find the area of a rectangle is Length * width and we already have one dimension here, so we simply plug it in and make an equation to the find the unknown measurement
12 * d = 24
d = 24/12
d = 2
So the missing dimension is 2 feet
Now we simply find the perimeter of the rectangle using the formula
2 ( length + width)
= 2 (12 + 2 )
= 2 ( 14 )
= 28 feet
Distributive Property to solve the equation. 5(x - 6) + 8 = 7x- 8 (Type the value of x.)
Answer:
x=−7
Solving for X:
Step 1: Simplify both sides of your equation.
5x−22=7x−8
Step 2: Subtract 7x from both sides.
5x−22−7x=7x−8−7x
−2x−22=−8
Step 3: Add 22 to both sides.
−2x−22+22=−8+22
−2x=14
Step 4: Divide both sides by -2.
-2x/-2 = 14/-2
^ x = -7
THEREFORE:
x is −7
I'm stuck on this question.
Answer:
Fred's total net worth is $61,900
Step-by-step explanation:
For net worth, add assets together and then subtract the liabilities from the total:
90,000 + 12,500 + 20,200
122,700 - (53,000 + 5,800 + 2,000)
61,900
Answer:
$61,900
Explanation:
Add all the assets: 90000 + 12500 + 20200 = 122700
Add all the liabilities: 53000 + 5800 + 2000 = 60800
Total assets - liabilities: 122700 - 60800 = $61900

In the triangle above, the measure of A is 66°, and the measure of B is 68°. What is the measure of C?
Answer:
46°
Step-by-step explanation:
Given that :
Angle, A = 66°
Angle B = 68°
The sum of angles in a triangle is given by :
A + B + C = 180° (sum if angles una triangle)
66° + 68° + C = 180°
134° + C = 180°
C = 180° - 134°
C = 46°
Hence, angle C is 46°
