900 ml.
Daisy fills jug A with water. She then fills jug B by pouring in water from jug A.
After this, there is 500 ml of water remaining in jug A.
Work out the volume of each measuring jug.
Help please
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.
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.

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).

What exactly is a positive exponent?A positive exponent indicates that the base should be multiplied by that many.
Give a good illustration of a positive exponent.For instance, 10 should be multiplied by 10x10x10, or 1000, if the number is 103. The variable x should be multiplied by itself nine times if the variable is x raised to 9.
What does "simplifying exponent" mean?It is possible to simplify exponents by putting exponent-containing algebraic formulas into a simpler form that prevents further simplification.
The given expression is (5x⁶y²)³
Simplifying it further we get,

in triangle ABC , angle A = 30 degrees and angle C = 35 degrees. what is angle B degrees?
Answer:
115°
Step-by-step explanation:
The sum of the three angles in a triangle is always 180°
m∠A + m∠B + m∠C = 180°
m∠B = 180 - m∠A - m∠C
m∠B = 180 - 30 - 35 = 115
8. Un vendedor de bebidas en un conocido pueblo mágico analiza sus ventas en días festivos
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]

SOLUTION
Let's list the values first. These are
48, 65, 60, 45, 54, 64, 70 and 45
Now, we have to arrange these values from the smallest to the largest. Doing this we have
45, 45, 48, 54, 60, 64, 65, 70.
The median will be between the middle items which are 54 and 60. So we will find the median by the following way
[tex]\begin{gathered} \text{Median = }\frac{54+60_{}}{2} \\ \text{Median }\frac{114}{2} \\ \text{Median = 57} \end{gathered}[/tex]Therefore, the Median is 57°F
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%.

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.

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
