The radius of a circular wheel is 35 centimeter how many turns will it make in order to cover 1100meters ?
Answer: 500
Step-by-step explanation:
Given
The radius of the wheel is [tex]r=35\ cm\ or\ 0.35\ m[/tex]
Distance covered by wheel [tex]d=1100\ m[/tex]
Distance covered in one revolution is equal to the circumference of the wheel
Circumference of the wheel is [tex]2\pi r[/tex]
Insert the values
[tex]\Rightarrow 2\pi \times 0.35\\\Rightarrow 2.2\ m[/tex]
No of revolution is given by
[tex]\Rightarrow \dfrac{1100}{2.2}=500[/tex]
Thus, 500 revolutions is required.
600 raffle tickets were sold for $5 each. There is one $500 first prize and three $200 second prizes. The remainder of the tickets do not win anything. What is the expected value of this raffle?
Answer:
its -$3.17
Step-by-step explanation:
500-5=495
200-5=195
the remainder of the tickets is -$5
the expected value is $495 x 1/600 + $ 19583/600 + (-$5) 596/600= -$3.17

Which expression is represented by the phrase "the square of y decreased by the quotient of 28 and 7"? * 1 point
Answer:
y² - 4
Step-by-step explanation:
Give the expression :
"the square of y decreased by the quotient of 28 and 7"?
Expressing Mathematically ;
Square of y = y²
Quotient of 28 and 7 is obtained by taking the division of 28 by 7
Dividing 28 by 7 ; 28/7 = 4
Hence, decreasing y² by 4 ; we have ;
y² - 4

Step-by-step explanation:
slope = (difference in y)/(difference in x)
slope = (1 - 6)/[-3 - (-5)]
slope = -5/2
Answer:
-5 / 2
Step-by-step explanation:
y2 - y1 / x2 - x1
1 - 6 / -3 - (-5)
-5 / 2
please help me... anyone?
Step-by-step explanation:
a.) you have to substitute f(5) into the formula
f(x) = 3x^2 + 5
you do this by inserting five into your x :
f(x) = 3x^2 + 5
f(5) = 3(5^2) + 5
= 3(25) + 5
= 75 + 5
f(5) = 80
b.) to solve for g(5) ,, you do the exact same but with the formulae g(x) = 11x - 10
g(x) = 11x - 10
g(5) = 11(5) - 10
= 55 - 10
g(5) = 45
. we can see that f(5) is the greater quantity ,, furthermore it is greater by 35 . =
f(5) = 80 g(5) = 45
80 - 45
= 35

A=5m, b=12, c=?
Answer:
c=13
Step-by-step explanation:
a^2+b^2=c^2
25+144=169
The square root of 169 is 13.
Answer:
c= 13
Step-by-step explanation:
a^2+b^2= c^2 = 25+144= 169 root of 169 is 13
PLEASE HELP WILL AWARD BRAINLIEST:)
Answer:
x = 4 units
Step-by-step explanation:
By geometric mean theorem:
Length of perpendicular
[tex] =\sqrt{2\times 6}[/tex]
[tex] =\sqrt{12}[/tex]
Next, by Pythagoras theorem:
[tex] x^2 = 2^2 + (\sqrt {12})^2 [/tex]
[tex] \therefore x^2 = 4 + 12 [/tex]
[tex] \therefore x^2 = 16 [/tex]
[tex] \therefore x =\sqrt{ 16 }[/tex]
[tex] \therefore x =4\: units[/tex]
Which would it be please?Help if you can.
Answer:
B
Step-by-step explanation:
Area = length times width, in this case, both length and width is x.
While 5 and 2 are the lengths and widths for the unshaded part.
x^2 = whole square
x^2 - (5)(2) = area of shaded region

Samuel is preventing a boulder from rolling down a hill with a slope of 35°. If the boulder
weighs 322 pounds, how much force is he exerting to hold the rock in place?
Answer:
1,809.98 lb*m/s^2
Step-by-step explanation:
First, we want to know how much weight of the boulder is projected along the path in which the boulder can move.
The weight of the boulder is:
W = 322lb*9.8 m/s^2 = (3,155.6 lb*m/s^2)
This weight has a direction that is vertical, pointing downwards.
Now, we know that the angle of the hill is 35°
The angle that makes the direction of the weight and this angle, is:
(90° - 35°)
(A rough sketch of this situation can be seen in the image below)
Then we need to project the weight over this direction, and that will be given by:
P = W*cos(90° - 35°) = (3,155.6 lb*m/s^2)*cos(55°) = 1,809.98 lb*m/s^2
This is the force that Samuel needs to exert on the boulder if he wants the boulder to not roll down.

Kyle bought x pencils. He paid $1.24, including tax, per pencil. He gave the cashier $20 and received $5.12 in change. How many pencils did Kyle purchase?
Question 3 options:
14.88
15
1.24
12
Answer:
he bought 12 pencils
Step-by-step explanation:
20 - 5.12 = 14.88
14.88 / 1.24 = 12
Answer:
[tex]he \: give \: 20 \: to \: cashier \: and \: recieve \: 5.12 \\ so \: 20 - 5.12 = 14.88 \\ 1.24per \: pencil \: h e \: buy \: x \: penil \: then \\ x \times 1.24 = 14.88 \\ x = \frac{14.88}{1.24} = 12 \\ 12 \: number \: of \: pencil \: \\ thank \: you[/tex]
