Lee has a bag with 500 quarters. Some are the older eagle quarters, and others are the newer state quarters. She pulls out 10 quarters at random. Four are eagle quarters, and 6 are state quarters. Based on this sample, how many of the quarters in the full bag were likely to be eagle quarters? 400 200 100 300
Answers
Answer:
400
Step-by-step explanation:
The number of eagle quarters likely to be in the bag is 200.
Option B is the correct answer.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of quarters = 500
Out of the 10 quarters.
Eagle quarters = 4
This means,
Percentage of eagle quarters,
= 4/10 x 100
= 40%
Now,
40% of 500 quarters.
= 40/100 x 500
= 200
Thus,
The full bag is likely to have 200 eagle quarters.

How far did I travel to reach my destination on each day of my three-day Trip?
a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination.
b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination.
c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
Answers
The total distances you traveled to reach your destination on each day of your three-day trip are as follows:
a) Day 1 = 40 miles
b) Day 2 = 30 miles
c) Day 3 = 11 miles.
How the total distances are determined:The total distances are determined using proportions.
Proportion refers to the fractional value of the whole number or quantity.
a) Day 1:
The fractional distance traveled = ⁵/₈
The remaining distance to travel = 15 miles
15 miles = ³/₈ (1 - ⁵/₈)
Proportionately, the total distance = 40 miles (15 ÷ ³/₈)
b) Day 2:
The distance traveled = 18 miles
The remaining distance to travel = ²/₅
The distance traveled = ³/₅ (1 - ²/₅)
³/₅ = 18 miles
Proportionately, the total distance = 30 miles (18 ÷ ³/₅)
c) Day 3:
The distance traveled = ⁵/₁₁
The distance to travel = 6 miles
The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)
Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

Therefore, the best estimate for the total time Maria was with her sister is close to [ ] (0 hours) ( 1/2 hour) ( 1 hour) ( 1 1/2 hour) (2 hours)
Answers
Answer: It was exactly 61 minutes and 50 seconds
Step-by-step explanation:
Answer:
\(\text{$\dfrac{2}{5}$ hour $\approx \dfrac{1}{2}$ hour}\)
\(\text{$\dfrac{5}{8}$ hour $\approx \dfrac{1}{2}$ hour}\)
\(\text{Total $\approx$ 1 hour}\)
Step-by-step explanation:
Time they played a game
\(\dfrac{2}{5}=\dfrac{2 \times 2}{5 \times 2}=\dfrac{4}{10}\)
\(\text{As $\dfrac{5}{10}=\dfrac{1}{2} \implies \dfrac{4}{10}\approx \dfrac{1}{2} \implies \dfrac{2}{5}\approx \dfrac{1}{2}$ hour}\)
Time they read a book
\(\text{As $\dfrac{4}{8}=\dfrac{1}{2} \implies \dfrac{5}{8}\approx \dfrac{1}{2}$ hour}\)
Total time
Therefore, the best estimate for the total time is:
\(\implies \dfrac{2}{5}+\dfrac{5}{8} \approx \dfrac{1}{2}+\dfrac{1}{2}=1\; \text{hour}\)
Exact solution
\(\begin{aligned}\implies \dfrac{2}{5}+\dfrac{5}{8} & = \dfrac{2 \times 8}{5\times 8}+\dfrac{5\times 5}{8\times 5} \\\\& = \dfrac{16}{40}+\dfrac{25}{40} \\\\& = \dfrac{16+25}{40} \\\\& = \dfrac{41}{40}\\\\ & = \dfrac{40+1}{40}\\\\ & = \dfrac{40}{40}+\dfrac{1}{40}\\\\ & = 1+\dfrac{1}{40}\\\\ & = 1\frac{1}{40}\; \text{hour} \end{aligned}\)

How to simplify the expression?The expression in the context of this problem is defined as follows:
(-3.78b + 12) - (4.82b - 16).
The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

Evaulate each expression when n = 2.3
N + 8n2 - 17=
Answers
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62

I am creating a garden that is rectangular. If the following ordered pairs are
the corners, what is the perimeter of my garden?
(-7, 10), (-7, 2), (4, 10), (4, 2)
Answers
Answer: the perimeter of the garden is 38 units.
Step-by-step explanation:To find the perimeter of the garden, we need to add up the lengths of all four sides.
Starting with the bottom side, we can use the coordinates (-7, 2) and (4, 2). The distance formula tells us that the distance between these two points is:
d = √[(4 - (-7))^2 + (2 - 2)^2]
= √[11^2 + 0^2]
= √121
= 11
So the bottom side has a length of 11.
Moving to the right side, we can use the coordinates (4, 2) and (4, 10). Again using the distance formula, we get:
d = √[(4 - 4)^2 + (10 - 2)^2]
= √8^2
= 8
So the right side has a length of 8.
For the top side, we can use the coordinates (4, 10) and (-7, 10):
d = √[(-7 - 4)^2 + (10 - 10)^2]
= √11^2
= 11
So the top side also has a length of 11.
Finally, for the left side, we can use the coordinates (-7, 10) and (-7, 2):
d = √[(-7 - (-7))^2 + (2 - 10)^2]
= √8^2
= 8
So the left side has a length of 8.
Adding all four side lengths together, we get:
Perimeter = 11 + 8 + 11 + 8
= 38
To find the perimeter of the garden, we need to add up the lengths of all four sides.
Starting with the bottom side, we can use the coordinates (-7, 2) and (4, 2).

Step-by-step explanation:
20x + 20 = 200
-20 -20
20x. = 180
x = 9
Answer:
\(x=9\)
Step-by-step explanation:
Assuming you'd like to solve for \(x\), start with:
\(20(x+1)=200\)
Distribute the \(20\) into the \((x+1)\):
\(20x+20=200\)
Subtract \(20\) from both sides of the equation:
\(20x=180\)
Divide both sides of the equation by the coefficient of \(x\), which is \(20\):
\(x=9\)

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15
