Answer:
2 7/12
Step-by-step explanation:
You have to get all the fractions to a common denominator. Smallest common denominator would be 12.
5 and 3/4 turns to 5 and 9/12
2/3 turns to 8/12
2 and 1/2 turns to 2 and 6/12
8/12 + 2 6/12 = 3 2/12
5 9/12 - 3 2/12 = 2 7/12
2 7/12 being the remaining amount

How many one-to-one correspondences are there between two sets with
6 elements each?
Answer:
6 * 5 * 4 * 3 * 2 * 1, i.e. 6! or 720. Of course, since both sets have the same number of elements, you can't have one-to-one without being onto, aka a surjection, so “one to one correspondence” is the right term (or bijection—merci, M.

If you deposit ₱10,000 into an account that earns 5% annual interest compounded semiannually, how long will it take until there is ₱12,000 in the bank account
Answer:
t = 3.69 ≈ 3. 7 years
Step-by-step explanation:
Given :
P = 10,000
r = 5%= 0.05
A = 12,000
n = 2 ( because it is compounded semi - annually )
[tex]A = P (1 + \frac{r}{n})^{nt}\\[/tex]
[tex]12000 = 10000(1 + \frac{0.05}{2})^{2 t}\\\\1.2 = ( 1 + \frac{0.05}{2})^{2t}\\\\1.2 = (1.025)^{2t}\\\\log \ 1.2 = 2t \ log \ 1.025\\\\2t = \frac{log 1.2 }{log 1.025} \\\\2t = \frac{0.1823}{0.0247}\\\\2t = 7.3805\\\\t = 3.69[/tex]

A fish tank initially contains 15 liters of pure water. Brine of constant, but unknown, concentration of salt is flowing in at 4 liters per minute. The solution is mixed well and drained at 4 liters per minute. Let xx be the amount of salt, in grams, in the fish tank after tt minutes have elapsed. Find a formula for the rate of change in the amount of salt, dx/dtdx/dt, in terms of the amount of salt in the solution xx and the unknown concentration of incoming brine cc. dxdt
Answer:
dx/dt = 4c - 4x/15
Step-by-step explanation:
a. Find a formula for the rate of change in the amount of salt, dx/dtdx/dt, in terms of the amount of salt in the solution
Let c be the concentration of the incoming brine in grams per liter. Since it flows in at a rate of 4 liters per minute, the mass flow in is thus 4m.
Let x be the mass of salt present at time, t. The concentration of salt present at time, t is thus mass of salt/volume of tank = x/15. Since the well mixed solution is drained at 4 liters per minute, the mass flow out is thus 4x/15.
The net rate of change of amount of salt dx/dt = mass flow in - mass flow out
dx/dt = 4c - 4x/15

Urelia made a deposit to her checking account. She had $104.00 in currency: $7.64 in coins; and checks for $83.29, $257.77, $1,332.68, and $3,984.05. What
was her total deposit?
$5,769.43
$6,126.43
$5.985.43
$6,432.43
None of these choices are correct.
Answer: $5,769.43
Step-by-step explanation:
For us to get the value of the total deposit, we have to add all the deposits together whether they're cash deposits or check deposit. This will be:
= $104.00 + $7.64 + $83.29 + $257.77, $1,332.68 + $3,984.05
= $5,769.43
Therefore, the total deposit is $5,769.43

Since ED=EF=5
then F=D=48°
Then E=180°-48°-48°=84°
Find the volume of a sphere with a diameter of 4 inches. Use 3.14 for π
.
Round your answer to the nearest hundredth.
The volume of the sphere is cubic inches.
Answer:
33.51 cubic inches
Step-by-step explanation:
Formula for volume of a sphere is V= 4 /3 · π · r3
We know the diameter is 4, and the radius is half the diameter, so the radius is 2.
V = 4 /3 · π · [tex]2^{3}[/tex]
≈ 33. 51032
Rounded to the nearest hundreth is 33.51.

What are the characteristics of a density curve? Select all that apply.
A. The total area under the curve is always 1.
B. The area between any two points is always 0.5.
C. The curve always falls on or above the horizontal axis.
D. The percentage of values between any two points is the area of the figure
formed by the curve and the x-axis.
Answer:
b
Step-by-step explanation:
From the characteristics of a density curve, option (A), (C), (D) are the correct answers.
What is a density curve?A density curve is a graph that shows probability. It is an idealized representation of a distribution in which the area under the curve is defined to be 1.The area under the curve is equal to 100 percent of all probabilities.
For the given situation,
Properties of density curves
• A density curve is always on or above the horizontal axis.
• The area underneath a density curve is exactly 1.
• The area under a density curve and above any range of values is the
relative frequency of all observations that fall in that range.
Hence we can conclude that from the characteristics of a density curve, option (A), (C), (D) are the correct answers.

x+138 = 180
x = 180-138
x =42
Answer:
42°
Step-by-step explanation:
138° + x = 180°
180° - 138° = 42°

The diameter of a pipe is normally distributed, with a mean of 0.8 inch and a variance of 0.0025. What is the probability that the diameter of a randomly selected pipe will exceed 0.9 inch?
Answer:
0.02275
Step-by-step explanation:
Standard deviation is the square root of variance
Standard deviation= Square(0.0025)= 0.05
Because of the normally distributed, the z- score for 0.9 inches is:
(0.9-0.8)/0.05= 2
-> P(x<= 0.9)= P(2) = 0.97725
-> P (x>= 0.9)= 1-0.97725 = 0.02275
