Answer:
7.5 feet
Step-by-step explanation:
Hello there.
1. We know that the scale drawing is 0.75 inches long.
2. If 1 whole inch on the map is equivalent to 10 feet in real life, then how much feet in real life would be 0.75 inches on the map?
0.75 is equivalent or equals to 3/4 as a fraction.
Multiply 3/4 with 10 feet to get 7.5 feet.
Hope this helped!

Rollie borrowed some money from his sister. Their brother wanted to know how much Rollie borrowed, but Rollie wouldn’t tell him. Instead, Rollie gave his brother a riddle.
“Each month, I paid our sister one-third of the amount I still owed her plus an additional $3. At the end of 3 months, I still owed her $3.”
Solve the riddle to find out how much money Rollie borrowed from his sister.
Explain how you arrived at your solution.
By working with fractions, we will see that the amount that Rollie borrowed from his sister is $31.50.
How much Rollie borrowed?Let's say that Rollie borrowed a quantity x.
The first month, Rollie returns one third of x + $3, so now he owes:
x - x/3 - 3 = (2/3)*x - 3
the second month returns another third of what he owes plus $3, so now he returns:
(1/3)*((2/3)*x - 3) + 3 = (2/9)*x + 2
So no he owes:
(2/3)*x - 3 - (2/9)*x - 2 = (4/9)*x - 5
Finally, on the third month he returns:
(1/3)*((4/9)*x - 5) + 3 = (4/27)*x - 5/3 + 3 = (4/27)*x + 4/3
Now he owes:
(4/9)*x - 5 - (4/27)*x - 4/3 = (8/27)*x - 19/3
And that is equal to $3, what he owes at the end of the third month, so we need to solve:
(8/27)*x - 19/3 = 3
(8/27)*x = 3 + 19/3 = 28/3
Solving for x, we get:
x = (27/8)*(28/3) = 31.5
So Rollie borrowed $31.5 from his sister.

A coin jar contains 12 quarters, 15 dimes, and 23 nickels. Find the probability that a Karen will choose a dime from the jar and then Mikah will choose a quarter from the jar.
Write the probability as a fraction in simplest form.
6/25 is incorrect
Answer:
18/245.
Step-by-step explanation:
Total number of coins = 12+15+23 = 50.
Prob(Karen chooses a dime) = 15/50 = 3/10.
Prob(Mikah then chooses a quarter) = 12/49. ( Karen has already removed one coin)
Prob(of Karen choosing a dime then Mikah a quarter)
= 3/10 * 12/49
= 36/490
= 18/245.

Answer:
You have to share number too
You decide that you are going to flip a coin, and a six sided die.
What is the probability of the following events?
Tails and an even number? (Round to two decimal places)
Tails and the number 9?
Heads or a number bigger than 4? (Round to two decimal places)
Heads or the number 2? (Round to two decimal places)
Probability helps us to know the chances of an event occurring. The probability of getting a tail and an even number is 0.25.
What is Probability?
Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Since a coin has two faces, therefore, the probability of getting either of the sides of the coin is (1/2). While a die has six faces, so the probability of getting any side of the die is (1/6).
A.) The probability of getting a tail and an even number can be written as,
[tex]\text{Probability of getting a tail} = \dfrac{1}{2}[/tex]
[tex]\text{Probability of Even Number(2,4,6) } = \dfrac{3}{6} = \dfrac{1}{2}[/tex]
[tex]\text{Probability (Tails and an even number)} = \dfrac12 \times \dfrac12 = 0.25[/tex]
B.) The Probability of getting tails and the number 9 can be written as,
[tex]\text{Probability of getting a tail} = \dfrac{1}{2}[/tex]
[tex]\text{Probability of Number 9} = \dfrac{0}{6} = 0[/tex]
[tex]\text{Probability of the tails and the number 9} = 0[/tex]
C.) The Probability of getting Heads or a number bigger than 4 can be written as,
[tex]\text{Probability of getting a Head} = \dfrac{1}{2}[/tex]
[tex]\text{Probability of a number bigger than 4 (5,6) } = \dfrac{2}{6} = \dfrac{1}{3}[/tex]
[tex]\text{Probability (Heads or a number bigger than 4 )} = \dfrac12 + \dfrac13 = \dfrac{5}{6} = 0.83333[/tex]
D.) The Probability of getting Heads or the number 2 can be written as,
[tex]\text{Probability of getting a Head} = \dfrac{1}{2}[/tex]
[tex]\text{Probability of the number 2} = \dfrac{1}{6}[/tex]
[tex]\text{Probability (Heads or the number 2 )} = \dfrac12 + \dfrac16 = \dfrac{8}{12} = 0.6666[/tex]

A) The median of the set of scores is 78.
B) The mean of the set is less than the median.
C) The mode of the set of scores is 93
D) The mean of the set is more than the median.
The mean of the set is less than the median. Option B is correct.
Given that,
Norberto received the following scores on his last five spelling tests 93, 66, 78, 85, and 98.
The mean of the values is the ratio of the total sum of values to the number of values.
Here,
Marks scored by Norberto in 5 spelling tests are 93, 66, 78, 85, and 98.
Mean of marks score = total marks scored / total spelling test
Mean of marks score = (93 + 66 + 78 + 85 + 98) / 5
Mean of marks score = 420 / 5 = 84
Now,
In order to get the median,
Arrange the marks in ascending order,
66, 78, 85, 93, 98
n = 5
median = (n + 1) / 2th term
= (5 + 1) / 2th term
= 6 / 2 = 3 th term
Median = 85
Here, 85 > 84 implies the median is more than the mean.
Thus, the mean of the set is less than the median. Option B is correct.

What is the value of x in the equation 1/3x − 2/3 =− 18?
Answer:
x = -52
Step-by-step explanation:
[tex]\frac{1}{3}x-\frac{2}{3}=-18[/tex]
Let us solve for x.
[tex]\frac{1}{3}x=-18+\frac{2}{3}[/tex]
[tex]\frac{1}{3}x=-\frac{18*3}{1*3} +\frac{2}{3}[/tex]
[tex]\frac{1}{3}x=-\frac{54}{3} +\frac{2}{3}[/tex]
[tex]\frac{1}{3}x=\frac{-54+2}{3}[/tex]
[tex]\frac{1}{3}x=\frac{-52}{3}[/tex]
Use cross multiplication to find the value of x.
[tex]\frac{1x}{3}=\frac{-52}{3}[/tex]
[tex]3*1x=3*-52[/tex]
[tex]3x=-156[/tex]
Divide both sides by 3.

Answer:
x = -1, y = 0 or (-1, 0)Step-by-step explanation:
We have two equations :
-5x - y = 5x = 7y - 1Take the value of x in Equation 2 and substitute in Equation 1.
-5(7y - 1) - y = 5-35y + 5 - y = 5-36y = 0y = 0Now, take the value of y and substitute in Equation 2.
x = 7(0) - 1x = -1Solution
x = -1, y = 0 or (-1, 0)Answer:
The lines intersect at the point (-1, 0)
Step-by-step explanation:
−5( )−y=5
-5(7y-1) - y = 5 substitute the x=7y-1 into first equation
-35y + 5 - y =5 multiply -5
-36y + 5 = 5 combine like terms
-36y = 0 subtract 5
y=0 divide by -36

Use a system of equations to solve the following problems
1) Find the value of two numbers if their sum is 11.9 and their difference is 0.5.
Answer:
The answer is x= 6.2 and y= 5.7
Step-by-step explanation:
Let the two numbers be x and y.
1st condition:
x+y= 11.9 --- (1)
2nd condition:
x-y=0.5--- (2)
Solving 1 and 2
x+y= 11.9 --- (1)
x-y=0.5--- (2) (here +y and -y will get cancelled)
_____________
2x= 12.4
x= 12.4/2 = 6.2
∴x= 6.2
Now, put x= 6.2 in equation (1) ( u can put in eqn 2 also)
6.2+y= 11.9
y= 11.9-6.2= 5.7
∴y= 5.7
To recheck you can put the value of x and y in any of the eqns.
The LHS will be equal to RHS if the values we got are correct.

What is the five-number summary of this data set? {403, 276, 649, 786, 274, 189, 654, 652, 572} Drag the numbers into the boxes to correctly complete the five-number summary.
Answer:
Minimum: 189
Maximum: 786
Median: 572
Lower quartile: 275
Upper quartile: 653
Step-by-step explanation:
Listing the numbers in order from least to greatest, we have: 189, 274, 276, 403, 572, 649, 652, 654, 786.
From this, we can see that the smallest (minimum) value is 189, and the largest (maximum) value is 786.
We can find the the median by taking off a number from each side of the number set one by one. When done, we can see that the number in the middle is 572, so that is our median.
To find the upper and lower quartiles, split the number set in half where the median lies and find the median of those two sections.
Q1: 189, 274, 276, 403
274 + 276 = 550
550 ÷ 2 = 275
--------------------------
Q3: 649, 652, 654, 786
652 + 654 = 1306
1306 ÷ 2 = 653
So, the lower quartile range is 275, and the upper quartile range is 653.
hope this helps!
