What is 51% of 200 in steps?
Answer:
51% of 200 =
102
Step-by-step explanation:
51 x 200 = 10200
100 1 = 100 10200/100 = 102
percentages is out of 100
Another way:
51/100 is .51 so just multiply it by 200!
.51 x 200 = 102
Hope this helps you out! :)
Answer:
102 StepsStep-by-step explanation:
How you get 51% of 200 is by multiplying 51 by 200 then dividing the value of 51 times 200 by 100.
51 ⋅ 200 = 10200 ÷ 100 = 102 Steps
So, 51% of 200 equals 102 Steps

If y varies directly as and y= 10 when x = 2, then what is the value of y when x = 4?
A)
2.5
B)
20
C)
40
D)
80
Answer:
B)20

y=10 when x=2 and varies directly so y=5*x
when x=4 then y=5*x=5*4=20
plz tell formula of Cotθ plz fully explain
Answer:
1. cos(2π + θ) = cosθ
2. tan(2π + θ) = tanθ, cot(2π + θ) = cotθ.
explanation:
cot(2π + θ) = cotθ. The Trigonometric ratios of angle 2π - θ: Thinking of θ as an acute angle, 2π -θ ends in the 4th Quadrant where only cosine is positive. 2π -θ means going 1 full turn from A to A and then returning to the M' that means as much as θ.
Answer: cos(2π + θ) = cosθ, tan(2π + θ) = tanθ, cot(2π + θ) = cotθ.
Can anyone help me please ??
Answer:
A. 100 per deposit
Step-by-step explanation:
for every one deposit made, you see your y value increasing by 100
Answer: Choice A is correct
=================================================
Explanation:
Each time x goes up by 1, y goes up by 100 (eg: from 50 to 150, so 150-50 = 100).
We then say,
slope = rise/run
slope = (change in y)/(change in x)
slope = (100)/(1)
slope = 100
The rate of change is $100 per deposit
------------------------------
We could also use the slope formula. Pick any two points on the diagonal line. Let's say we picked (1,150) and (3,350)
m = (y2-y1)/(x2-x1)
m = (350-150)/(3-1)
m = (200)/(2)
m = 100
Or we could pick (0,50) and (1,150) as our two points
m = (y2-y1)/(x2-x1)
m = (150-50)/(1-0)
m = (100)/(1)
m = 100
Either way, the slope is m = 100.

At work, greg makes $14 for every hour that he works. Write a function to represent how many dollars, D, greg has entered from working, then calculate how much money he made after working 5 hours
Answer:
[tex]D(h) = 14 h[/tex]
He made $70 in 5 hours
Step-by-step explanation:
Given
[tex]Hourly\ Rate = \$14[/tex]
Required
Determine a function to represent the amount he made
Determine the amount made in 5 hours
To determine the function (D), we simply multiply the hourly rate by the number of hours worked (h).
So, we have:
[tex]D = Hourly\ Rate * h[/tex]
[tex]D = 14 * h[/tex]
[tex]D = 14 h[/tex]
Represent D as a function
[tex]D(h) = 14 h[/tex]
Solving (b): Amount in 5 hours
We have that
[tex]D(h) = 14 h[/tex]
In this case:
[tex]h = 5[/tex]
So, we have:
[tex]D(5) = 14 * 5[/tex]
[tex]D(5) = 70[/tex]
Hence, he made $70 in 5 hours

What is the constant of proportionality expressed as miles per second?
Answer: The constant of proportionality is _____________miles per second.
Answer:
Proportionality constant = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
From the graph attached,
Data set representing the relation between seeing lightning and the hearing thunder is,
{(15, 3), (25, 5), (35, 7), (45, 9)}
Since, Distance from lightening (d) ∝ Time between lightening and thunder (t)
d = kt
Here k = proportionality constant
k = [tex]\frac{d}{t}[/tex]
From the data set one point is (15, 3).
k = [tex]\frac{3}{15}[/tex]
k = [tex]\frac{1}{5}[/tex] miles per second
Therefore, proportionality constant is [tex]\frac{1}{5}[/tex] miles per second.

You are told that a third powered polynomial has zeroes at -1, 2, 5.
Part A. Write the three factors of the polynomial
Part B. Write the polynomial in standard form
Answer:
a) factors of polynomial are: (x+1)(x-2)(x-5)
b) the required polynomial in standard form is: [tex]\mathbf{x^3-6x^2+3x+10}[/tex]
Step-by-step explanation:
The polynomial has zeros at -1,2,5
Part A) Write the three factors of the polynomial
we have x=-1, x=2 and x=5 as zeros of polynomial
so factors will be:
(x+1)=0, (x-2)=0, (x-5)=0
So, factors of polynomial are: (x+1)(x-2)(x-5)
Part B) Write the polynomial in standard form
For finding polynomial, we will multiply all the factors i.e
(x+1)(x-2)(x-5)
[tex](x+1)(x-2)(x-5)\\=(x(x-2)+1(x-2))(x-5)\\=(x^2-2x+x-2)(x-5)\\=(x^2-x-2)(x-5)\\=x(x^2-x-2)-5(x^2-x-2)\\=x^3-x^2-2x-5x^2+5x+10\\=x^3-x^2-5x^2+5x-2x+10\\=x^3-6x^2+3x+10[/tex]
So, the required polynomial in standard form is: [tex]x^3-6x^2+3x+10[/tex]

Which pair of events are independent of each other?
A.
selecting an ace from a deck of cards, and then drawing another ace without replacing the first
B.
drawing a red paperclip from a bag of paperclips, and then drawing another red paperclip without replacing the first
C.
drawing a ball from a bag, and then drawing another ball without replacing the first
D.
getting an even number on the first and second roll of the die
PLZ EXPLAIN
Answer:
D
Step-by-step explanation:
Rolling a die and getting a certain number will not change the chances of you getting the same number a second time. A normal die will always have a 1/2 chance of rolling an even number. However, the other answer choices will make the likelihood of getting the same type of event again slimmer as you remove one of the objects from being chosen again. An example for the first option would be drawing an ace from a deck of 52 cards where you only have 4 aces, so the chance on the first draw would have been 4/52 or a 7.7% chance while the next draw will be a 3/51 or 5.9% chance.
Three pipes A, B and C take 24, 36 and 32 hours to fill a pool, respectively. How long would it take the three pipes to fill the pool if pipe B is turned on 3 hours after pipe A and pipe C is turned on 1 hour after pipe B?
Answer:
12 hours
Step-by-step explanation:
Time taken by pipe A = 24 hours
Time taken by pipe B = 36 hours
Time taken by pipe C = 32 hours
To find:
How long would it take the three pipes to fill the pool if pipe B is turned on 3 hours after pipe A and pipe C is turned on 1 hour after pipe B?
Solution:
First of all, let us assume the total capacity of the pool.
Let us take LCM of 24, 36 and 32.
LCM of 24, 36 and 32 = 288
Let the total capacity of the pool = 288 units
Total units filled by pipe A in one hour = [tex]\frac{288}{24} = 12\ units[/tex]
Total units filled by pipe B in one hour = [tex]\frac{288}{36} = 8\ units[/tex]
Total units filled by pipe C in one hour = [tex]\frac{288}{32} = 9\ units[/tex]
Now, for the first 3 hours, only pipe A operates, so units filled in first three hours = [tex]12\times 3 =36\ units[/tex]
For the next one hour, A and B both operate together, so units filled in the next 1 hour = 12 + 8 = 20 units
Total number of units filled in 4 hours = 36 + 20 = 56 units
Units to be filled to completely fill the pool = 288 - 56 = 232 units
Now, after the 4th hours, all the pipes operate together.
So, number of units filled in each hour = 12 + 8 + 9 = 29 units
Time taken to fill 232 units = [tex]\frac{232}{29} = 8\ hours[/tex]
Total time taken = 4 + 8 = 12 hours
