Answer:
1650
Step-by-step explanation:
If there are 275 pages and each page can fits 6 coins then you multiply 6 by 275.
Answer:
6 on each page; 1,650 in total coins for all the pages
Step-by-step explanation:
1. The first step is to multiply 1/6*6 to find out how many coins can fit on one page.
2.The second step is to multiply 6 *275. That equals 1,650

Yana and Amber play a word game using tile letters. Each person takes 7 tiles from a set of tiles. Points are earned by using the chosen letter tiles to make a word. Points are lost when tiles are returned to the set and new tiles are chosen. The table shows the points earned or lost by each girl in their first six turns of the game.
Answer:
A Yana's average number of points is 0.5 points greater than Amber's
Step-by-step explanation:
i added up all of Yana's points = 15
I added up all of Amber's points = 12
then i divided them both by 6 because there is 6 numbers total so then i got
Yana = 2.5 Amber = 2
2.5 - 2 = 0.5 so Yana's average number of points is 0.5 points greater than Amber's

Answer:
A: Yana's average number of points is 0.5 points greater than Amber's

percent of change of $49 to $149
To find the percentage change, here is what we can do:
difference/original value x 100%
The difference: 149-49 = 100
The original value:149
The percentage change:
100/149 x 100%
=67.11409...%
Therefore the answer is 67.1%(corr. to three significant figures)
Hope it helps!
The percent of change from $49 to $149 is approximately 204.08%.
To calculate the percent of change from $49 to $149, we first find the difference in the two amounts.
The difference between $149 and $49 is $149 - $49 = $100.
Then, we divide the difference by the original amount (in this case, $49) to find the change in terms of the original amount.
This gives us $100 / $49 = 2.0408.
To convert this to a percentage, we multiply by 100. 2.0408 x 100
= 204.08%.
So the percent of change from $49 to $149 is approximately 204.08%.
Each time a solid bicycle wheel turns, the bicycle travels 197cm. What is the area of the wheel?
Answer:
38809/(4pi) cm^2
Step-by-step explanation:
So the circumference of the wheel is 197. So to find the radius, we divide by 2 pi. So now we have 197/(2pi) as the radius. Now we have to find the area, so it is 38809/(4pi)
The area of the solid wheel is 3090 cm².
What are the circumference and diameter of a circle?The circumference of a circle is the distance around the circle which is 2πr.
The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.
We know circumference is the distance around the circle which is 2πr.
Given, Each time a solid bicycle wheel turns, the bicycle travels 197cm.
Therefore,
2πr = 197.
r = 197/π×2.
r = 31.37 cm.
Therefore, The area of the solid wheel is,
πr².
= 3.14×(31.37)² cm².
= 3090 cm².

The following function is quadratic.
f(x)=(x+4)(x-6)
What is the value of the positive x-intercept of the graph of the related equation y = (x+4)(x-6)?
Answer: 6
You replace f(x) or y with 0, and then solve for x
y = (x+4)(x-6)
(x+4)(x-6) = y
(x+4)(x-6) = 0
x+4 = 0 or x-6 = 0 .... zero product property
x = -4 or x = 6
The x intercepts are -4 and 6. In this case, only 6 is the positive x intercept.
side note: The term "root" is another way to say "x-intercept"

What is answer for # 38 and #39???
Answer:
f(x) + g(x) = 6x^2 + 28x + 36
Step-by-step explanation:
Thirty eight
You begin to solve this by writing it like this [just as you have it].
f(x) = x^2 + 5 Now put g(x) where you see x
f(g(x)) = [g(x)]^2 + 5 Now substitute the right side of g(x) wherever you see g(x)
f(x - 4) = [x - 4]^2 + 5 Expand the brackets
f(x- 4) = x^2 - 8x + 16 + 5
f(x - 4) = x^2 - 8x + 21
=======================
Thirty Nine
f(x) = (x + 4)^2
g(x) = 5(x + 2)^2
Expand f(x)
f(x) = x^2 + 8x + 16
Expand g(x)
g(x) = 5(x^2 + 4x + 4) Remove the bracketsg(x) = 5*x^2 + 5*4x + 5*4 Perform the multiplicationg(x) = 5x^2 + 20x + 20f(x) + g(x) = x^2 + 8x + 16 + 5x^2 + 20x + 20
f(x) + g(x) = 6x^2 + 28x + 36

Paws at play made a total of $1234 grooming 22 dogs. Paws at Play charges $43 to groom each small dog and $75 for each large dog.
a. Write a system of equations that can be used to determine the number of small and large dogs that were groomed.
b. How many large dogs did Paws at Play groom?
Answer:
Answer (a):
s + l = 22 ... (i)
43s + 75l = 1234 ... (ii)
Answer (b)
9 large dogs.
Step-by-step explanation:
Paws at Play made a total of $1234 grooming 22 dogs.
Paws at Play charges $43 to groom each small dog and;
$75 for each large dog.
Let the number of small dogs be 's'
And the number of large dogs be 'l'
A system of equations will be:
s + l = 22 ... (i)
43s + 75l = 1234 ... (ii)
Solving this set of simultaneous equations by elimination, we simply multiply (i) by 43 to get;
43s + 43l = 946 ... (i)
43s + 75l = 1234 ... (ii)
Subtracting (i) from (ii) we get;
32l = 288 , l = [tex]\frac{288}{32}[/tex] = 9
So there are 9 large dogs.

1. -4 and 3/10 and 4.51010910921... are all rational numbers.
2. Yes 81 is a perfect square because its square root is 9 which is a real number.
3. 5
4. Well the closest perfect square to 52 is 49 and 64. 52 is closer to 49 and the square root of 49 is 7 so the estimated value of the square root of 52 is about 7.
False- every square root is not rational because some aren't perfect squares, meaning the result is a decimal that keeps going forever.

Yogesh has 3 quarters, 1 dime, and 2 pennies
Answer: Yoghes has $0.87
Step-by-step explanation: We want to know the total amount of money that Yogesh has:
each quarter values 25¢, a dime values 10¢, and a penny values 1¢
(or the values can be written as $0.25, $0.10 and $0.01 respectively)
Yogesh has 3 quarters, so this means he has: 3*$0.25 = $0.75
he has 1 dime, so in dimes, he has: $0.10
he has 2 pennies, so in pennies, he has: 2*$0.01 = $0.02
If we sum up the 3 amounts, we have:
Total = $0.75 + $0.10 + $0.02 = $0.87
Suppose you have a 1/10 chance of winning with a scratch-off lottery ticket. If you buy 3 tickets, what is the probability of winning with all 3
Answer:
0.001
Step-by-step explanation:
We are given that
Suppose you have the probability of winning with a scratch -off lottery ticket,P(A) =[tex]\frac{1}{10}[/tex]
Probability:It is defined as the possibility of an event that is occurred or not.
It is obtained by dividing the number of favourable cases with total number of cases.
The formula of finding out the probability of an event
P(E)=[tex]\frac{Number\;of\;favourable\; cases}{Total\;number\;of\;cases}[/tex]
We have to find the probability of winning 3 lottery
The probability of winning all three tickets,[tex]P(A AA)=P(A)\cdotP(A)\cdotP(A)[/tex]
Therefore, the probability of winning all 3 lottery =[tex]\frac{1}{10}\times \frac{1}{10}\times \frac{1}{10}[/tex]
The probability of winning all three tickets,P(A AA)=[tex]\frac{1}{1000}[/tex]

According to the Doppler effect, if a car with a blowing horn is moving toward you, the pitch you hear will
Answer:
If a car with a blowing horn is moving toward you, the pitch sounds higher than the actual emitted frequency.
Step-by-step explanation:
In figure,
V= speed of wave
U= speed of car
When car moving towards you, then
Car travels a distance in time T = VT
Wave travels a distance in time T = UT
From figure,
change in wavelength (λ') = VT - UT= T(V-U)
Now,
V = λ' f' (f' →frequency observed by you)
f' = V ÷ λ' = [tex]\frac{V}{T(V-U)}[/tex]
We know that
[tex]\frac{1}{T}[/tex] = f
Then,
f' = [tex]\frac{Vf}{V-U}[/tex]
f' = [tex]\frac{f}{1-\frac{U}{V} }[/tex]
Hence, we can say that
frequency increases as source moves toward you.
Answer:
B. Increase
Step-by-step explanation:
The closer together the crests, the higher the frequency (or pitch)
