A brick has a mass of 18.4kg and a volume of 923cm°. Evaluate the density of the brick in g/cm3 rounded to 3
The density of brick can be obtained for the given case as 197.616 g/cm³.
What is the ratio of two numbers?The ratio of two numbers a and b can be written as a : b = a/b.
The ratio of two quantities is the unit rate of one quantity with respect to the other.
The mass and volume of the brick are 18.4 kg and 923cm³ respectively.
Mass can be converted into gram as 18.4 × 1000 = 18400 g.
Since, the density is given as ratio of mass and volume.
It can be calculated as below,
⇒ 182400 ÷ 923 = 197.616 g/cm³.
Hence, the density of the brick can be obtained as 197.616 g/cm³.

A man goes into a store and says, “If you give me as much money as I have with me now, I will spend $10 in your store.” The store owner agrees, and the man spends the money.
He goes into a second store and again says, “If you give me as much money as I have with me now, I will spend $10 in your store.” Again, the owner agrees, and the man spends the money.
In a third store, he repeats his proposition. The proprietor agrees, and the man spends the money.
At this point, the man has no money left. How much money did he have to begin with?
Answer:
$8.75
Step-by-step explanation:
Let x = the amount the man originally had
The man has $x and says "if you give me $x, I will spend $10."
y = amount he has after 1st proposition = x + x - 10 = 2x - 10
He repeats this procedure, now with $2x-10 in his pocket...
z = amount he has after 2nd proposition = (2x - 10) + (2x - 10) - 10 = 4x - 30
He repeats this procedure, now with $4x-30 in his pocket...but this time he is left with zero dollars...
r = amount he has after 3rd proposition = (4x-30) + (4x-30) - 10 = 8x-70 = 0
8x - 70 = 0,
x = $8.75

Insight number 2: to evaluate the limit of a:
1. Rational function: you can factorize and cancel out what you can
2. Radicals (subtractions of square roots): multiply and divide by the
conjugate. For example:
Vx2 + 1 - x
x? +1 - x2
x2 +1-x=
(V x2 +1 + x)
Vx2 + 1 + x
V.x2 + 1 + x
1
Vx2 +1 + x
3. Trigonometric functions: try to connect your limit with important
sin (x)
trigonometric limits like limx40 = 1
If you are stuck with a trig limit, express all the trig functions in terms
of sine and cosine.
4. If you are composing continuous functions, you can pass the limit
inside the external function: Cimz-a f(g(x)) = f(lim,-a 9(x))

19. Craig Deloy's bank computes 4.25 percent interest on a daily basis. He had $1,250 in the account
for 20 days. He then makes a deposit of $450 and makes no transactions for 10 days. He then
withdraws $300 and makes no transactions for 8 days.
a. How much interest does he earn in the 38 days total?
Answer:
Interest he earn in the 38 days total = $2458.57
Step-by-step explanation:
As given,
Rate of interest (R)= 4.25% = 0.0425
Principal (P)= $1250
Now,
Simple Interest (S.I) for 20 days = P×R×T
= 1250×0.0425×10
= 531.25
⇒Interest for 20 days = $531.25
Now,
Total amount = P + S.I = $1250 + 531.25 = $ 1781.25
As He then makes a deposit of $450 and makes no transactions for 10 days.
⇒Total amount become = $1781.25 + 450 = $2231.25
Now,
S.I for next 10 days = 2231.25×0.0425×10
= 948.28125
⇒Interest for next 10 days = $ 948.28125
∴
Total amount = $2231.25 + 948.28125 = $ 3179.53125
As He withdraws $300 and makes no transactions for 8 days.
⇒Total amount become = $ 3179.53125 - 300 = $ 2879.53125
Now,
S.I for next 8 days = 2879.53125×0.0425×8
= 979.040625
⇒Interest for next 8 days = $ 979.040625
a.)
Interest he earn in the 38 days total = Interest in 20 days + next 10 days + next 8 days
= $531.25+948.28125+979.040625
= $2458.571875 ≈ $2458.57
∴ we get
Interest he earn in the 38 days total = $2458.57
Mr. Lenz has received several orders for apples at his farm
stand. He needs to know how many people ordered 12
apples so he can fill bags of 12.
Would a dot plot or a histogram be a more appropriate way to display the
data for this situation?
A. A histogram, because Mr. Lenz wants to know all of the data for a
single value
O B. A dot plot, because Mr. Lenz wants to know all of the data for a
single value.
C. A histogram, because Mr. Lenz wants to know how the data fall
into different intervals or ranges.
D. A dot plot, because Mr. Lenz wants to know how the data fall into
different intervals or ranges.
Answer:
A, Histograms give values where as dot plots are focused on a trend.

If the volume of a cone with the same height as a cylinder equals the volume of the cylinder, the equation for the radius of cone Rin terms of the radius of cylinder r is:
Answer: R = √(3*r^2)
Step-by-step explanation:
For a cylinder with radius r and height H, the volume is:
V = pi*r^2*H
For a cone of height H, and with a base of radius R, the volume is:
V = (1/3)*pi*R^2*H
In this case, we know that both figures have the same height, and the same volume, then we can write:
pi*r^2*H = (1/3)*pi*R^2*H
Now we can divide by pi in both sides to get:
(pi*r^2*H)/pi = ((1/3)*pi*R^2*H)/pi
r^2*H = (1/3)*R^2*H
Now we can divide both sides by H:
(r^2*H)/H = ((1/3)*R^2*H)/H
r^2 = (1/3)*R^2
Now we want to write R in terms of r.
Then we need to isolate R in the above equation:
r^2 = (1/3)*R^2
3*r^2 = R^2
√(3*r^2) = R
R = √(3*r^2)

A bacteria sample is growing exponentially, as a seen in the table below.
Which exponential regression equation best represents this data? (Round values to the nearest tenth.)
a) y=22.3(1.4)^x
b) y=20.5(1.9)^x
c) y=15.1(0.8)^x
d) y=32.6(1.6)^x
Answer:
b) y=20.5(1.9)^xStep-by-step explanation:
As per data in the table:
The initial number is 20The growth rate is about twiceThis is best matching the function:
y = 20.5(1.9)^xoption b)
Lunches can be made consisting of exactly one entrée, one drink, and one snack. If all lunch options are equally likely, what is the probability of randomly choosing a lunch that
does not contain the veggie wrap
has milk or water, and
has fruit as the snack.
Write your answer as a percentage, to the nearest percent.
Entrée Chicken Cutlet Veggies Wrap Lasagna
Drink Milk Water Iced Tea
Snack Fruit Chips Jello
%
Answer:
4/27=14.8%
Step-by-step explanation:
In order to solve this, we have to see first each option possible, there are 2/3 of possibilities that a random Entrée ends up being Chicken Cutlet or Lasagna, then you have again 2/3 chances to get milk or water, and as you only want fruit the chances are 1/3 that you get that.
In order to calculate if this could happen at random we have to multiply all of the odds:
[tex]Probability: \frac{2}{3} *\frac{2}{3} *\frac{1}{3} \\Probability: \frac{2*2*1}{3*3*3} \\Probability: \frac{4}{27}[/tex]
So we know that for every 27 times you pick a lunch at random, 4 times it will not have the Veggie Wrap, contain milk or water, and will have fruit as the snack.
There are 2/3 of possibilities that a random Entrée ends up being Chicken Cutlet or Lasagna, then you have again 2/3 chances to get milk or water, and as you only want fruit the chances are 1/3 that you get that.
We need to now multiply the odds:
2/3x2/3x1/3
2x2x1/3x3x3
4/27
So we know that for every 27 times you pick a lunch at random, 4 times it will not have the Veggie Wrap, contain milk or water, and will have fruit as the snack.
So now we know it is, %15 rounded but 14.8% not rounded.
