Answer:
A whole number divided by a unit fraction is the same as multiplying a whole number by the inverse of the unit fraction.
Step-by-step explanation:
Given
[tex]8 \div \frac{1}{5} = 40[/tex]
[tex]8 * 5 = 40[/tex]
Required
Explain why both expressions are correct
No dropdown to select from. So, I will provide a general solution.
When a number is divided by a fraction.
Take for instance:
[tex]8 \div \frac{1}{5}[/tex]
The above can be expressed as the product of the number and the inverse of the fraction.
The inverse of 1/5 is 5.
So, we have:
[tex]8 \div \frac{1}{5} = 8 * 5[/tex]
The result of the above expression is:
[tex]8 \div \frac{1}{5} = 8 * 5 = 40[/tex]
I think im right again but i would like confirmation. thanks
Krishaun has $5, $10, and $20 coins worth a total of $560. She has the same number of $5 coins as $10 coins, and the same number of $10 coins as $20 coins. How many $20 coins does Krishaun have?
a.16
b.15
c.20
d.28
e.17
f = t = n five ten and twenty
5n + 10n + 20n = 560
35n = 560
n = twenty dollar coins = 16

Step-by-step explanation:
Camille buys a cake for $\$24.99$ . She also buys $12$ brownies. Each brownie costs the same amount. She spends $\$39.99$ on the cake and the brownies.
Camille finds the cost of each brownie by calculating $(39.99\ -\ 24.99)\ \div\ 12$ . Tanya finds the cost of each brownie by solving the equation $39.99\ +\ 12b\ =\ 24.99$ , where $b$ is the cost of each brownie.
Which approach uses the sequence of operations necessary to find the cost of each brownie: Camille’s, Tanya’s, both, or neither? Explain why.
Respond in the space provided.
Answer:
39.99-24.99=15
15/12=$1.25
$1.25 per brownies
Camille approach correct sequence.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Camille buys a cake for $24.99.
She bought total 12 brownies.
She spend total $39.99 on cake and brownies.
So, to calculate the cost of each brownies
24. 99 + 12b = 39.99
12b = 39.99 - 24.99
12b = 15
b = $1.25

6. Now that the curve pieces are determined, use those pieces as sections of a complete coaster. By hand or by using a drawing program, sketch a design of Ray and Kelsey's coaster that includes the shape of the g(x) and f(x) functions that you chose in the Parts A and B. You do not have to include the coordinate plane.

26-12=14
14/7=2
?-9=2
?=11
Answer:
g = 11
Step-by-step explanation:
⇒ 26 -12 = 7(g - 9) + 12 -12
⇒ 14 = 7(g - 9)
⇒ 14/7 = 7(g - 9)/7
⇒ 2 = g - 9
⇒ 2 +9 = g - 9+9
⇒ 11 = g

What equation below shows that the cost, c, depends on how many $5 hats, h, someone buys?
c = 5h
c = h + 5
h = 5 + c
h = 5c
Answer: c = 5h
Step-by-step explanation:
C is equal to the total cost, and h is equal to the number of hats bought.
So, as a verbal equation, we have:
total cost = price x number of hats bought
We know the price ($5) and the variables, so we can substitute these:
c = 5h

What are the advantages of taking a random sample instead of surveying an entire population?
Answer:
Answer is below
Step-by-step explanation:
Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. Selecting subjects completely at random from the larger population also yields a sample that is representative of the group being studied. This provides lack of bias towards the subject of the survey. It's overall more efficient, faster, and pushes the idea of simplicity through surveys.
Answer:
Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. It offers a chance to perform data analysis that has less risk of carrying an error. ... There is an equal chance of selection. ... It requires less knowledge to complete the research. ... It is the simplest form of data collection.

Answer: final balance is $-90
Step-by-step explanation:
37 - 90 = -53
-53 + 18 = -35
-35 - 55 = -90
Answer:
Im pretty sure its -$90
Step-by-step explanation:
It started with $37 and then a withdraw of $90 so subtract $37 by 90 so that will be -$55 then add $18 dollars which then will be -$37. Finally, a withdrawal of $55 so subract -$55 from -$37 and that will give you -$90.

The measures of two angles of a triangle are 75 and 62º. Find the measure of the third angle.
13°
c. 470
b. 43°
d. 137
Answer: B 43
Step-by-step explanation:
Well for a triangle it has to be equal to 180 so you would add 75 and 62 to get 137 so you would add each answer to 137 and whichever one equals 180 is the answer therefor stating that the answer is B 43.
