10 girls and 15 boys sit a test.
The mean mark for the boys is 70. The mean mark for the girls is 82.
Work out the mean mark for the whole class.
Answer:Mean mark of whole class= 74.8
Step-by-step explanation:
Mean = Total marks of student / Number of students
Total marks of boys = Number of boys x Mean mark for boys
=15 x 70=1,050
Total marks of girls = Number of girls x Mean mark for girls
=10 x 82=820
Mean of whole students = Total marks of student / Number of students
= (1,050 + 820)/ (10+15)
=1870/25
=74.8

2. Adam borrows $6,000 from his parents today for university fees and he promises
to pay a lump sum of $6,900 in 3 years' time. Calculate the following quantities
for the repayment arrangement:
(a) the effective annual interest rate.
(b) the equivalent simple annual interest rate.
Answer:
A) 4.77%.
B) 5%.
Step-by-step explanation:
Given that Adam borrows $ 6,000 from his parents today for university fees and he promises to pay a lump sum of $ 6,900 in 3 years' time, to calculate the effective annual interest rate and the equivalent simple annual interest rate the following calculations must be performed:
A)
6,900 = 6,000 x (1 + X / 1) ^ 3x1
6,900 = 6,000 x 1X ^ 3
6,900 = 6,000 x 1 x 4.77 ^ 3
Thus, the interest rate of said investment is 4.77% per year.
B)
(6,900 - 6,000) / 3 = 300
6,000 = 100
300 = X
300 x 100 / 6,000 = X
30000 / 6,000 = X
5 = X
Thus, the simple interest rate would be 5% per year.

Answer:
938 feet
Step-by-step explanation:
The diagonal is the hypotenuse of a right triangle with side lengths 900 ft and 264 ft. The Pythagorean theorem tells you how to compute its length.
d² = 900² +264² = 879,696
d = √879,696 ≈ 937.92 . . . . feet
They would walk about 938 feet.
Help!!!!!!!!!find the equation of the linear function q(16)=1 that is parralel to f(x)=1/3x+39
It wants it in slope intercept form
Answer:
[tex]q(x)= \frac{1}{3} x -\frac{13}{3}[/tex]
Step-by-step explanation:
So you have (16, 1)
When two linear functions are parallel, they have the same slope.
So function q also has a slope of 1/3x. You have a set of points so you can plug them in a slope intercept equation to find b.
y= mx+b
m= slope
y= y-intercept
1= 1/3(16) +b
1 - (16/3) = b
b= -13/3
so then, [tex]y= \frac{1}{3} x -\frac{13}{3}[/tex]

In 2010 an item costs $9.00. The price increases by 1.5% each year. How much will it be in 2030?
Answer:11.7
Step-by-step explanation:
1. Recognize variables. Starting price is 9, it’s increasing by 1.5% each year, the question asks for the price in 20 years.
2. Convert percentage to decimal. Most calculators won’t understand multiplying by percentages, and instead will understand multiplying by decimals. A decimal is something we can easily work with. It is more commonly taught to work with decimals as well. With that said 1.5% equals .015. (The number in the ones place in the percentage is always in the hundredths place when converted to a decimal, the tens to the tenths, the hundreds in the percentage to the ones place in the decimal, the hundredths in the percentage to the ten thousandths in the decimal. Basically, every individual number [the 5 in 1.5] moves two spaces to the right when going from percentage to decimal form, likewise two to the left going from decimal to percentage form. 23%=.23, 104%=1.04, 0.5%=.05, 1.234%=.01234)
3. Make your equation
20(9*(.015))+9
+9 is your starting point
9*(.015) gives you the amount the price increases per year
20 is multiplied then to that increased price for the next 20 years
4. Crunch em numbers
PEMDAS
The cost of the item in 2030 is $10.449.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation
We have,
Cost of an item = $9
The item increases per year = 1.5%
Now,
The equation for the cost of the item after x years.
= 9[tex](100 + 1.5)^x[/tex]
Now,
There are 10 years from 2010 to 2030.
So,
x = 10
= 9 [tex](1 + 0.015)^{10}[/tex]
= 9 x [tex]1.015^{10}[/tex]
= 9 x 1.161
= 10.449
Thus,
The item will cost $10.449 in 2030.

The admission fee at an amusement park is 1.5 dollars for children and 4 dollars for adults. On a certain
day 369 people entered the park, and the admission fees collected totaled 1016 dollars. How many
children and how many adults were admitted?
Answer:
184 children and 185 adults!
Step-by-step explanation:
So let's suppose there are x children who entered the park that day, then there will be (369-x) adults who entered the park that day.
So we have an equation!
1.5x+4(369-x)=1016
1.5x+1476-4x=1016
Then we swivel things around a bit.
1476-1016=4x-1.5x
2.5x=460
x=184
There are 184 children in that park that day! Wow, that's a lot of people, next we calculate the number of adults:
369-184
=185
OK, 184 children and 185 adults!
