Step-by-step explanation:
The density formula is: Density =mass/vol
---> 2.76 =812.04 / Vol ---> Vol= 812.04 / 2.76= 294.22
The answer is 294.22
The volume of the emerald with mass 812.04 grams and density 2.76 grams/cubic cm is [tex]294.22 \: \rm cm^3[/tex] approximately.
How are density, volume and mass of a substance related?Suppose that a finite amount of substance is there having its properties as:
mass of substance = m kgdensity of substance = d kg/m³volume of that substance = v m³Then, they are related as:
[tex]d = \dfrac{m}{v}[/tex]
For this case, we have:
mass of substance = m = 812.04 gdensity of substance = d = 2.76 g/cm³volume of that substance = v cm³Then, we have:
[tex]d = \dfrac{m}{v}\\\\v = \dfrac{m}{d} = \dfrac{812.04}{2.76} \approx 294.22 \: \rm cm^3[/tex]
Thus, the volume of the emerald with mass 812.04 grams and density 2.76 grams/cubic cm is [tex]294.22 \: \rm cm^3[/tex] approximately.

A bicycle store costs $2800 per month to operate. The store pays an average of $50 per bike. The average selling price of each bicycle is $90. How many bicycles
must the store sell each month to break even?
The store must sell bicycles each month to break even.
(Type a whole number.)
Answer:
70 Bikes
Step-by-step explanation:
[using b as a variable for bikes]
2800=-50b+90b
[2800 is total cost of store with-50 being cost per bike and 90 being selling point of bike]
2800=40b [simplified by combining -50 with 90]
70=b [divided 2800 by 40 to get the break even for the store]
At a carnival in a small town, the entry fee was $8 per person, and the cost for each ride ticket was $2. The inequality below was used to determine if the town met its goal of earning more than $1,650 each day the carnival was open. 8p + 2r > 1,650 The following variables were used: p = the number of people who attended the carnival r = the number of ride tickets sold• On Friday, 150 people attended the carnival.

Mitchell went on a shopping trip to Kensington. He purchased a pair of headphones originally
priced at $50 but discounted 60%. If sales tax in Kensington is 15%, what was the total cost?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The total cost of the pair of headphones is $23.
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% = 50/200 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
105 = 10/100 = 1/10
We have,
Original price of the headphones = $50
60% of $50
= 60/100 x 50
= $30
The price of the headphones after the discount.
= $50 - $20
= $20
The amount of sales tax.
= 15% of $20
= 15/100 x 20
= $3
The total cost.
= $20 + $3
= $23
Thus,
The total cost of the pair of headphones is $23.

Step-by-step explanation:
Timia needs so cash in a hurry she owns her car outright and is considering a title loan. The lender told timia she could borrow 1750 for 1 month
The question is incomplete ; the fee which Timia would pay isn't given. And this is needed to compute the APR on the loan.
I would assume that the fee which Timia would pay as interest on the 1 - month loan is x
Answer:
r = x / 145.83333
Step-by-step explanation:
If interest paid, I = x
Principal, P = $1750
And period (time) of loan = 1 month = (1/12) = 0.0833333
Rate = r
Using the simple interest formula :
Interest = Principal * rate * time
x = 1750 * r * 0.833333
Make r the subject :
x = 145.83333r
Divide both sides by 145.83333
Hence, the rate value , r becomes :
r = x / 145.83333
Therefore, the student can just input the appropriate, interest value in place of x and obtain the correct and exact answer (I do not want to use an hypothetical value for x) .

determine the value of k if g(x) =4x+k is a tangent to f(x)= -x² +8x +20
Answer:
22
Step-by-step explanation:
222
The value of k in the given functions is; 24
What is the value of the function to the tangent?
We are given the functions;
g(x) = 4x + k as a tangent to f(x) = -x² +8x +20
For f(x) = -x² +8x +20
=> f'(x) = -2x + 8
Thus, slope of tangent at ( x , y) = -2x + 8
For g(x) = 4x + k
g'(x) = 4.
Thus, slope is 4
Therefore;
-2x + 8 = 4
-2x = -4
x = 2
Putting 2 for x in f(x) gives;
f(2) = -2² + 8(2) + 20
f(2) = 32
Thus, it is at (2 , 32)
Thus, (2 , 32) lies on g(x) = 4x + k
4(2) + k = 32
k = 32 - 8
k = 24

Kindly check the complete version of the question on the picture attached below :
Answer:
B.) 4 * 3 * 3
Step-by-step explanation:
Unit volume of cube = 48 unit³
Using the volume relation :
Volume = Length * width * height
V = l * w * h
To obtain the odd representation, we calculate the volume of the dimensions given in the option and select the option which does not yield a volume of 48 unit³
A.) 8 * 2 * 3 = 48 unit³
B.) 4 * 3 * 3 = 36 unit³
C.) 6 * 2 * 4 = 48 unit³
D.) 3 * 2 * 8 = 48 unit³
Hence, prism with dimension 4 * 3 * 3 cannot be one of Kyle's prism

Anchor: If you start with 50 g of a material, how much is half of that? How much is half of half? How much is half of that?
Answer:
Step-by-step explanation:
1/2 of 50 grams is the same thing as 50 divided by 2 which is 25
Now you take 1/2 of 25 grams. That's 25 divided by 2. Use your calculator if you're not sure 25 divided by 2 = 12 and 1/2 or 12.5
I think we're down to 1/2 of 12.5
1/2 of 12.5 is 6 and then 0.5/2 which is 0.25
So 1/2 of 12.5 is 6.25
If I left one out, leave a comment.
Just in case 1/2 of 6.25 = 6/2 = 3
1/2 of 0.25 = 0.25/2 = 0.125
so the answer here is 3.125
If I've misunderstood the question, leave a note for that too.
