Given that;Beginning typing speed = 30 word per minute
Ending typing speed = 48 word per minute
Find:Increase word per minutePercentage changeComputation:Increase word per minute = Ending typing speed - Beginning typing speed
Increase word per minute = 48 - 30
Increase word per minute = 18 word per minutes

John is two years younger than his sister, Annie. Last year, John was half Annie's age. How old are John and Annie now?
Answer: John is 3 and Annie is 5
Step-by-step explanation:
because to be half of someone's age while being to years younger it would have to be 2 and 4 - but then a year passed and so the are now 3 and 5.
Answer: John is 3 and Annie is 5
Step-by-step explanation:
Half of 4 is 2 so last year John was 2 and Annie 4 and like a year has passed we add 1 to 2 and 4 which helps us determine that John is now 3 and Annie 5
Please can you help me answer this
Answer:
a) The factors of x² + 3·x are x and (x + 3)
x² + 3·x = x·(x + 3)
b) The factors of 2·x² - 8·x are 2, x and (x - 4)
2·x² - 8·x = 2·x·(x - 4)
c) The factors of 6·x + 9·x³ are 3, x and (2 + 3·x²)
6·x + 9·x³ = 3·x·(2 + 3·x²)
d) The factors of 12·x³ - 4·x² are 4, x², and (3·x - 1)
12·x³ - 4·x² = 4·x²·(3·x - 1)
Step-by-step explanation:
The question relates to resolving a polynomial into its factors;
a) For the polynomial (quadratic) equation, x² + 3·x, we have;
x² + 3·x = x·(x + 3)
Therefore, x² + 3·x in factorized form is x·(x + 3)
b) For the polynomial (quadratic) equation, 2·x² - 8·x, we have;
2·x² - 8·x = 2·x·(x - 4)
Therefore, 2·x² - 8·x in factorized form is 2·x·(x - 4)
c) For the polynomial (cubic) equation, 6·x + 9·x³, we have;
6·x + 9·x³ = 3·x × (2 + 3·x²)
Therefore, 6·x + 9·x³ in factorized form is 3·x·(2 + 3·x²)
d) For the polynomial (cubic) equation, 12·x³ - 4·x², we have;
12·x³ - 4·x² = 4·x²·(3·x - 1)
Therefore, 12·x³ - 4·x² in factorized form is 4·x²·(3·x - 1).

Answer:
£ 186.20
Step-by-step explanation:
height = 6 cm = 0.06 m
Volume of gravel drive away = length * width * height
= 11 * 4 * 0.06
= 2.64 m³
Number of gravel bags needed = 2.64 ÷ 0.4
= 6.6
7 bags are to be purchased by him.
Cost of a bag = £ 38
Cost of 7 bags = 38 * 7 = £ 266
Discount = 30% of 266
[tex]= \frac{30}{100}*266[/tex]
= £ 79.80
Amount paid by Martin = 266 - 79.80
= £ 186.20
FUNDRAISING The baseball team plans to sell tins of popcorn and peanuts. The players have $900 to spend on products and can order up to 200 tins. They want to order at least as many tins of popcorn as tins of peanuts. A tin of popcorn costs $3, and a tin of peanuts costs $4. Define the variables and write a system of inequalities to represent this situation. Then list any constraints for the variables.
the constraints for the variables is 2
The required inequality is given as 3x + 4y ≤ 900.
Given that,
The baseball team plans to sell tins of popcorn and peanuts. The players have $900 to spend on products and can order up to 200 tins. They want to order at least as many tins of popcorn as tins of peanuts. A tin of popcorn costs $3, and a tin of peanuts costs $4.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Let, the number of pop-corn tin be x and the number of peanuts tin be y,
According to the question,
Cost of the x tin of popcorn = 3x
Cost of the y tine of peanuts = 4y
Now the sum of the cost of popcorn and peanuts must no exceed $900,
So
3x + 4y ≤ 900
Thus, the required inequality is given as 3x + 4y ≤ 900.

Answer:
A, 14
Step-by-step explanation:
Assuming that she has a total of d dollars, and spends half of it, then we have 1/2d. She then spends another 6 dollars, and therefore we would subtract. She is left with one dollar.
1/2d-6=1
Working backwards, we can solve for d, her total amount of money:
1/2d=7
d=14

The student council has $800 to spend on homecoming t-shirts. The number of t-shirts they can buy is a function of the price of the price of the t-shirt p, in dollars, given by n(p)= 800 over p.
Answer:
the price of the t-shirt is inversely proportional to the number of t-shirts to be bought.
Step-by-step explanation:
The total amount to be spent on t-shirts is $800.
The function;
n(p) = 800 / p (price in dollars)
as the price per shirt increases, the number of shirt decreases and the curve moves down towards zero. When the price per shirt decreases, the number of shirt increases moving the curve upwards to infinity
