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]
At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3. What is the density of the ice? Explain the steps you took to solve this problem.
Answer:
0.3
Step-by-step explanation
The formula to find density is m/v=p
m=mass
v=volume
p=density
---------------------------All we have to do is plug in 6g and 20cm^3
This will give us 6/20 which simplifies to 3/10
With this you can easily figure out that the decimal for 3/10 is 0.3
So the density of the ice is 0.3
Hope this helped!
Lana has a memory box that measures 18 inches wide by 9 inches deep. The height is 1.5 feet what is the volume of the box. IN INCHES!!!!!!!
Answer:
2916
Step-by-step explanation:
1.5 feet is 1 foot 6 inches, or 18 inches
volume is height * length * width, so 18 * 9 * 18 = 2916
Answer:
2,916 inches
Step-by-step explanation:
The formula for volume is length x width x height.
So, you will have to start to identify each of these.
First, though, because of 1.5 being feet and not inches, you must convert.
1 foot = 12 inches, so 1/2 foot = 6 inches. Meaning, 12 + 6, which is 18 inches.
Now, you can solve: 18 x 18 x 9 = 2,916.
Hope this helps! :)
A brownie recipe calls for 1 cup of sugar and 12 cup of flour to make one batch of brownies. To make multiple batches, the equation f=12s where f is the number of cups of flour and s is the number of cups of sugar represents the relationship. Which graph also represents the relationship? Explain how you know.
Answer:
A
Step-by-step explanation:
A because it is the only one the recipe calls for 1 cup of sugar and 1/2 cup of flour, the point is in the middle but also on one.

Please help me if you can thank you. For question A the answer is 5000 brochures. My question is how did they get that answer?
Answer:
Step-by-step explanation:
Company A's equation is 900+0.50x5,000
Company B's equation is 1,500+0.38x5,000
Both equal 3,400 and have to be multiplied by 5,000
find the volume of the cone using the given formula
Answer:
I believe your answer would be
Step-by-step explanation:
Using that formula, we can substitute in the values we need that are given to us in the question:
h = 12
r = 4
Now we need to use the formula.
V = 1/3 (pi) (4²) (12)
First lets do the exponent.
4² = 16
V = 1/3 (pi) (16) (12)
Now lets do pi × 16.
pi × 16 = 50.2654824574.
Now we have:
V = 1/3 (50.2654824574) (12)
Multiply 50.2654824574 and 12.
50.2654824574 × 12 = 603.185789489
Now all we have:
V = 1/3 (603.185789489)
Multiply them.
V = 201.06192983
So, your answer is V ≈ 201.06192983, or 201.
Lily and Mackenzie collected some stamps. If Lily gave 4 stamps to Mackenzie, Mackenzie would have twice as many stamps as Lily. If Mackenzie gave 4 stamps to Lily, they would have the same number of stamps. How many stamps did each girl have?
GIVING BRAINLIEST. PLS HELP. SHOW UR WORK TOO
Answer: hope this helps ♡
Lily had 16 stamps and Mackenzie had 20 stamps.
Step-by-step explanation:
Lily gives 4 stamps to Mackenzie
(Mackenzie) m + 4 = 2(L - 4) (Lily)
Solve for Lily:
m + 4 = 2L - 8
m + 4 + 8 = 2L
(m + 12) ÷ 2 = 2L ÷ 2
(m + 12) ÷ 2 = L
L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)
Mackenzie gives 4 stamps to Lily
(Mackenzie) m - 4 = L + 4 (Lily)
m - 4 = ((m + 12) ÷ 2) + 4
m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4
2m - 4 + 4 = (m + 12) + 4 + 4
2m - m = (m - m + 12) + 8
m = 12 + 8
m = 20 (we will substitute this value of m in the next equation)
L = (m + 12) ÷ 2
L = (20 + 12) ÷ 2
L = 32 ÷ 2
L = 16

Describe the angle relationship and solve for the x.
Answer:
x = 25
Step-by-step explanation:
The shown angles appear to be on a straight line
Angles on a straight line have a sum of 180°
That being said we can create an equation using this relationship
180 = x + 2 + 153
now we solve for x using basic algebra
step 1 combine like terms
153 + 2 = 155
now we have 180 = x + 155
step 2 subtract 155 from each side
180 - 155 = 25
155 - 155 cancels out
we're left with x = 25
Which one of the numbers does not belong in the following series?
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
A-FIVE
B-SEVEN
C-FOURTEEN
D-FORTY-ONE
E-ONE HUNDRED TWENTY-TWO
Answer:
i think 7
Step-by-step explanation:
Option B: SEVEN
The number that goes not belong in the following series is SEVEN
Given :
The numbers in the series is
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
First number is 2
[tex]2 \cdot 3 -1=5\\[/tex]
Lets multiply the previous term by 3 and subtract 1 to check the other terms
[tex]5 \cdot 3 -1= 14\\14 \cdot 3 -1= 41\\41 \cdot 3 -1= 122\\122 \cdot 3 -1= 365\\365 \cdot 3 -1= 1094\\1094 \cdot 3 -1= 3281\\[/tex]
From the series we can see that 7 does not belong to the series .
So, SEVEN does not belong to the series .

Find the missing angle.
Answer:
total angle of a triangle = 180°
other two angles = 85° , 65°
∴ the missing angle = 180 - ( 85 + 65 )
= 180 - 150
= 30

Answer:
Part A: 56
Part B: 43.9
Part C: I think the medain is more apropriate in this situation because it takes out the outlier , 3, that is affecting the mean
Step-by-step explanation:
Part A: To calculate the median you must have all of the numbers in numerical order so, 3,31,37,56,57,61,62, The medain is the number in the middle or closet to the middle. In this case 56 is directly in the middle so 56 is your median.
Part B: To find the mean you must add all of the values together and then divide by the number of values you have so when you add 3+31+37+56+57+61+62 it equals 307 and you divide it by 7 because there are 7 numbers in this data set and you get 43.9 when you round to the nearest tenth.
Part C: explanation in answer.
Hope this helps :)

for part a you can just go to an excel numbers in a column then click sum then click medien then select the column.
