At the country fair, Maya observes that the wheel of chance has 25 numbered slots. If each play costs a quarter, how much will Maya likely have to spend before she gets her winning number?
Answer:
6 1/4
Step-by-step explanation:
Given
Total number of wheel chance = 25
Each play = 1 quarter
1 play = 1/4
To calculate the amount Maya has to spend to get her winning number, we will say;
25 plays = x
Divide both expressions
1/25 = 1/4÷x
1/25 = 1/4x
Cross multiply
4x = 25
x = 25/4
x = 6 1/4
This mean that Maya will have to spend 6 1/4 before she gets her winning number

PLS HELP- Richard and Teo have a combined age of 33. Richard is 15 years older than twice Teo's age. How old are Richard and Teo?
Answer:
Teo= 9
Richard= 24
Step-by-step explanation:
x= Richard
y= Teo
33-15= 18
18÷2= 9
15+9=24
Teo is 6 years old and Richard is 27 years old.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
Let x be Teo's age, then Richard's age is 15 years older than twice Teo's age, or 15 + 2x. The combined age of Richard and Teo is 33, so we can write an equation:
x + (15 + 2x) = 33
Simplifying and solving for x, we get:
3x + 15 = 33
3x = 18
x = 6
So Teo is 6 years old and Richard is 15 + 2(6) = 15 + 12 = 27 years old.

Louis invested £2950 in a savings account for 5 years.
He was paid 1.9% per annum compound interest for each of the first 4 years.
He was then paid R% interest for the fifth year.
Louis had £3257 in his savings account at the end of the 5 years.
Work out the value of R.
Give your answer correct to 1 decimal place.
Answer:
2.4%
Step-by-step explanation:
The value of R is, 2.4%
What is Simple interest?A quick and easy method of calculating the interest charge on a loan is called a Simple interest.
Given that;
Louis invested £2950 in a savings account for 5 years.
He was paid 1.9% per annum compound interest for each of the first 4 years.
And, He was then paid R% interest for the fifth year.
Louis had £3257 in his savings account at the end of the 5 years.
Here, We know that;
⇒ Compound interest formula = Capital × (1 + r%) ⁿ
Where, n is time in years.
So, We can formulate;
⇒ £2950 × (1 + 0.019)⁴
⇒ £3180.67
And, For calculate R;
⇒ £3180.67 × (1 + R%)⁵ = £3257
⇒ R = 2.4%

what is half of 3/4 teaspoon
One method of finding the answer in the fraction form of 3/8 is
to multiply the fraction 1/2 by 3/4 ,
or, we can divide 3/4 by 2
i.e. 1/2 × 3/4
as, half = 1/2
so, we get,
=> 3/ 2×4
=> 3/8
=>0.375
Hence, One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons.

Mathilde has 20 pints of green paint. She uses 2/5 of it to paint a landscape and 3 /10 of it while painting a clover. She decides that, for her next painting, she will need 14 pints of green paint. How much more paint will she need to buy?
Answer:
8
Step-by-step explanation:
Total pints of paint = 20
For landscape :
2/5 * 20 = 8 pints
For clover :
3/10 * 20 = 6 pints
Total used = (8 + 6) = 14
Pints left = 20 - 14 = 6 pints
14 required for next painting
14 - 6 = 8 pints
8 more pints needed

Written as a simplified polynomial in standard form, what is the result when
(x - 2)^2is subtracted from 9x^2-8x?
Answer:
9x^2 - 10x -4
Step-by-step explanation:
It is set up like this
9x^2 - 8x
- (x-2)2
First solve (x-2)2
the answer is (2x-4)
so now you can do this instead
9x^2 - 8x
- 2x - 4
----------------------------------
9x^2 - 10x +4
9x^2 minus zero is 9x^2
-8x-2x is -10x
0- -4 is 4 because that is like saying 0 + 4 because double negatives equal a positive
A simpler way is to change all the numbers to the opposite sign and then change the minus to a plus
like this
9x^2 - 8x
+ -2x + 4
----------------------------------
9x^2 - 10x +4
Answer:

Find an order pair (x,y) that is solution to the equation 3x-y=8
Answer:

Step-by-step explanation:
You first make x 0 so it is -3x0 to cancel that out to find y. You then see that you get -y=8 so you make y positive by moving the negative to the other side to get y = -8. Then, you do the same type of process for x and get 2.67. I could be wrong but wanted help as much as I could!
