Find the circumference and area of the circle. Use 3.14 for π. Round to the nearest hundredth if necessary.
13m.
Answer:
81.64
Step-by-step explanation:
Answer:
Step-by-step explanation:
Please be explicit in labeling the radius. I will assume y ou meant r = 13 m.
Circumference formula: C = 2πr; area formula: A = πr²
Here, with r = 13 m, C = 2π(13 m) = 26π m = C = 81.68 m
and
with r = 13 m, A = π(13 m)^2 = 169π = A = 530.93 m^2

Is a triangle with side lengths of 10, 11, 14 a right triangle?
Answer:
no
Step-by-step explanation:
A right triangle has a formula a^2+b^2=c^2 with c being the longest side (hyponotuse). 10 squared is 100, 11 squared is 121, so add those and get 221. 14 squared is only 196 which is not equal to 221 so it is not a right triangle
Answer:
Yes

The amusement park is open for 11 hours if approximately 200 people can ride the swing in one hour what is the maximum amount of people that can ride the swing in one day
Answer:
2,200
Step-by-step explanation:
Number of hours amusement park opens = 11 hours
Number of people who ride the swing in one hour = approximately 200
what is the maximum amount of people that can ride the swing in one day?
Number of people that can ride the swing in one day = Number of hours amusement park opens × Number of people who ride the swing in one hour
= 11 × 200
= 2,200 approximately
Number of people that can ride the swing in one day = 2,200

Pryia and 3 friends go out to dinner and split the cost equally. The meal costs $98, tax is 9% and they leave a 20% tip based the cost of the meal. How much money does Pryia need?
Answer:
$42.14
Step-by-step explanation:
Given data
Cost of meal= $98
tax= 9%
Tip= 20%
Let us find the amount of the tax and the tip
Tax
=9/100*98
=0.09*98
=$8.82
Tip
=20/100*98
=0.2*98
=$19.6
Hence the total amount paid is
=98+8.82+19.6
=126.42
The amount paid by Pryia
=126.42/3
=$42.14

Answer:
VelocityStep-by-step explanation:
Acceleration is defined as the rate of change of velocity.
Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction.
So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).
Answer:
velocity
Step-by-step explanation:
The definition of acceleration is: Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
What is the solution to the following equation?
7x−5=2x+5
Answer:
x = 2
Step-by-step explanation:
7x−5=2x+5
step 1 add 5 to each side
-5 + 5 = cancels out
5 + 5 = 10
we now have 7x = 2x + 10
step 2 subtract 2x from each side
2x - 2x cancels out
7x - 2x = 5x
we now have 10 = 5x
step 3 divide each side by 5
5x / 5 = x
10 / 5 = 2
we' re left with x = 2

Step-by-step explanation:
subtract the areas of a circle from the area of a square and divide by 4
A_square = L x W
A_circle = pi x r^2
L, W= 12cm
r= 12/2cm
(A_square - A_circle) / 4
divide by 4 since the remaining portions are symmetrical

Solve equation by using the quadratic formula.
2x2 - 5x = 7
Let's solve your equation step-by-step.
2x2−5x=7
Step 1: Subtract 7 from both sides.
2x2−5x−7=7−7
2x2−5x−7=0
2x2+−5x+−7=0
Step 2: Use quadratic formula with a=2, b=-5, c=-7.
x=−(−5)±√(−5)2−4(2)(−7)/2(2)
x=5±√81/4
Answer:
x= 7/ 2

pls help i need to know what x/-4 + 6 < 11 is?!?!!?!?!
Answer:
x ∈ ( - ∞ , 20 )
Step-by-step explanation:
Given :
x / 4 + 6 < 11
Adding - 11 both we get:
= > x / 4 + 6 - 11 < 11 - 11
= > x / 4 - 5 < 0
Multiply by 4 both we get:
= > x - 20 < 0
Adding 20 both side we get:
= > x - 20 + 20 < 20
= > x < 20
Solution set x ∈ ( - ∞ , 20 )
Hence we get required answer!
9514 1404 393
Answer:
x > -20
Step-by-step explanation:
This is a "2-step" inequality with a negative coefficient.
x/-4 +6 < 11 . . . . . given
x/-4 < 5 . . . . . . . . subtract 6 from both sides
x > -20 . . . . . . . . .multiply both sides by -4
Because the multiplier is negative, the sense of the comparison must be reversed.
_____
Check
x = -24 should not be in the solution set: -24/-4 +6 < 11 ⇒ 12 < 11 . . . False
x = -16 should be in the solution set: -16/-4 +6 < 11 ⇒ 10 < 11 . . . True
A car wheel has a diameter of 27.1". How far will the car go when the wheels rotate 100 times?
Answer:
135.5"
Step-by-step explanation:
Answer:
8509.4
Step-by-step explanation:
The diameter has already been displayed so what I could simply do is solve the equation simply by using the formula for circumference using diameter (C=3.14 x 27.1) and that will get me 85.094 but thats how far it will get if it rotates 1 times so we must multiply it by 100 and move the decimal point 2 digits to the right and the final answer is 8509.4. 8509.4 (no mathematical unit) is how far the car can go when the wheels have a diameter of 27.1 and rotates 100 times.(please help!!)

Answer:
Step-by-step explanation:
How many questions are on the exam? Represent this by n.
Then 40% of n comes out to 12 questions, or more symbolically,
0.40n = 12, after which we get n = 12/0.40 = 30
Answers:
(1) 0.40n = 12 is the desired equation.
(2) n = 30 is the number of questions on the exam.
(3) See above for explanations.

Answer:
[tex]x^{2} - 25[/tex]
Step-by-step explanation:
Area is side x side, so naturally it would be: (x+5)(x - 5)... Though to simplify, those parenthesis can be FOILed. (Reminder: "FOIL" means First - Outer - Inner - Last)
[tex]x^{2} - 5x + 5 x - 25[/tex]
The 5x cancels out because 5x - 5x = 0
So that leaves us with:
[tex]x^{2} - 25[/tex]
=========================================================
Explanation:
Let's say we replace the "x+5" with some other letter. Let's use L for length.
We'll keep the width x-5 the same.
area = length*width
area = L*(x-5)
area = L*x + L*(-5)
area = xL - 5L
At this point, we would then plug in L = x+5 and distribute like so:
area = x( L ) - 5( L )
area = x( x+5 ) - 5( x+5 )
area = x^2 + 5x - 5x - 25
area = x^2 - 25
Side note: (x+5)(x-5) = x^2 - 25 is an application of the difference of squares rule.
