Ollie borrowed $5000 for 3 years at a compound interest rate of 10%.
How much did Ollie pay back?
Answer: Assuming interest rate is yearly, Ollie would have to pay back 6, 655 dollars :)
Step-by-step explanation:
The formula for compound interest is
Y = P(1 + r/m)^mt, with P being the initial deposit (5000), r being the interest rate (0.10), m being the amount of times it is compounded per year (1), and t being the number of years (3).
Two ways to write k/3+16
The two ways to write the expression k/3+16 are 1/3k + 16 and (k + 48)/3
How to rewrite the expression?From the question, the expression is given as
k/3+16
Start by factoring 1/3 out of the first term
So, we have the following expression
1/3k + 16
The above is one of the ways of rewriting the expression
Another way is by taking the LCM
So,we have
k/3+16 = (k + 48)/3
Hence, the equivalent expressions are 1/3k + 16 and (k + 48)/3

What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, Daisy has two measuring jugs, A and B, that together have a capacity of 900 ml, A jug of water is filled by Daisy. Afterward, she transfers water from jug A into jug B. Following this, jug A has 500 ml of water left.
Total volume = volume in jug A + volume in Jug B
If there are 500 ml of water remaining in jug A.
900 ml = 500 ml + volume in Jug B
volume in Jug B = 900 - 500
volume in Jug B = 400 ml
Thus, Daisy has two measuring jugs, A and B. The volume of each measuring jug will be A and B will be 500 ml and 400 ml.

y encuentra que si vende x bebidas en un día su utilidad (en pesos) está dada por.
y=-0.015x² +45x-2700
¿Cuál es la utilidad máxima por día festivo?
Answer: the maximum profit per holiday is 31050 pesos
Step-by-step explanation:
y=-0,015x²+45x-2700 (1)
It`s a quadratic equation like y=ax+bx+c
Therefore, the value of x at which y is maximal is:
[tex]\displaystyle\\x=\frac{-b}{2a} \\\\x=\frac{-45}{2(-0.015)} \\\\x=\frac{-45}{-0.03} \\\\x=\frac{45(100)}{0.03(100)}\\\\x=\frac{4500}{3} \\\\x=\frac{3(1500)}{3} \\\\x=1500[/tex]
Substitute the value of x into equation (1):
[tex]y=-0,015(1500^2)+45(1500)-2700\\\\y=-0.015(15*10^2)^2+67500-2700\\\\y=-0.015(15^2)(10^4)+64800\\\\y=-0,015*225*10^4+64800\\\\y=-150*225+64800\\\\y=-33750+64800\\\\y=31050 \ pesos[/tex]

Starting at sea level, a turtle descends at a constant rate to a depth of -yard relative to sea level in minute.
The turtle continues descending at this same rate.
What is the turtle's depth relative to sea level after the first minute?
Enter your answer as a simplified mixed number in the box
The turtle's depth relative to sea level after the first minute is 1.2 yards.
Given,
The depth where the turtle descends, d = -3/4 yards
The speed of turtle relative to sea level, t = 5/8 minutes.
We have to find the turtle's depth relative to sea level after the first minute.
The rate at which the turtle descends, r = d/t
r = d/t
r = (-3/4) / (5/8)
r = -3/4 × 8/5
r = -6/5 yards/minute
r = -1.2 yards/min
Now, the depth of turtle after the one minute, D = rt
Where, r = -1.2 yards/min and t = 1 min
Then,
D = -1.2 × 1 = -1.2 yards
That is,
The turtle's depth relative to sea level after the first minute is 1.2 yards

of his monthly budget should Jacob allocate for rent?
The percentage of monthly budget should Jacob allocate for rent is 27.7%.
What is termed as the percentage?A percentage is a ratio with the second term being 100. Percentage refers to parts per hundred. The term is derived from the Latin word per centum, that also means "per hundred." In mathematics, the symbol% stands for percent.For the given question;

Jacob's one week earning will be $1,350/2 = $675.
Considering there are 5 weeks in a months.
Jacob's one month earning will be $675×5 = $3,375.
The total monthly rent = $936.
Let 'x' be the percentage Jacob pay for the rent.
Then,
x% of 3,375 = 936
Simplifying the expression.
3,375x/100 = 936

Step-by-step explanation:
The sum of the three angles in a triangle is always 180°

11. Tom borrowed some money from his father seven months ago. Every month,
he pays back $400 to his father. Currently, he owes $2,500.
a) How much will he owe his father three months from now?
b) How much money did he borrow from his father?
In three months, he will owe his father $2500 less $1200, or $1300.
One of the four fundamental operations in mathematics is addition, along with subtraction, multiplication, and division. The entire amount or sum of the two whole numbers is obtained by adding them.
Tom's payment for 7 months is 400 * 7 = $2800.
He borrowed $5300 ($2500 plus $2800).
His monthly payment for three months is 400*3.

in new york state, the mean salary for high school teachers in 2017 was $81,410 with a standard deviation of $9,500. only alaska’s mean salary was higher! assume new york’s state salaries follow a normal distribution.
The percentage of New Yorks state teachers that earn between $7000 and $75000 is 13.63%.
What will the percentage be?Let the salary of the teachers be represented as x.
Mean = $81410
Standard deviation = $9500
In this case, the probability for normal distribution will be used. This is illustrated as P(a < Z < b).
where a = lower number.
b = higher number
Therefore, the probability of earning the amount will be:
P(70000 < X < 75000)
= P[(70000 - 81410/9500) < Z < (75000 - 81410/9500)
= P(-1.20 < Z < -0.67)
Using the z table to look for the value
= 0.8849 - 0.7486
= 0.1363
= 13.63%.
Therefore, the probability is 13.63%.

Answer:
A. Yes, Rectangle A is a scaled copy of rectangle B.
B. Yes, Rectangle B is a scaled copy of rectangle A.
C. No, Rectangle A is not a scaled copy of rectangle C.
Step-by-step explanation:
Rectangle A has dimensions 12x8 and Rectangle B has length 15x10.
We see that sides of A and B are proportional because
[tex]\frac{12}{15} = \frac{8}{10}[/tex]
So we say that since sides are proportional A and B are similar or scaled copy of each other.
Since A is smaller and B is bigger, a is 0.8 scaled copy of B. Similarly B has an enlargement scale factor = 1.25 Rectangle C has 30x15, not proportion with sides of A and B. Hence we find that C is neither a scaled copy of A nor B
