So far, he has ridden 70% of the bike course.
Percentage, which was adapted from the Latin word "per centum", which means "by the hundred", is a fraction or a ratio in which the value of whole is always 100. It is represented by the symbol "%".
The formula to get the percentage is:
Percentage = (Value / Total Value) × 100
If the total value of the bike course is 40 miles and the value which the percentage we are looking for is 28 miles, evaluating the equation:
Percentage = (Value / Total Value) × 100
Percentage = (28 / 40) × 100
Percentage = (0.7) × 100
Percentage = 70
Therefore, he has ridden 70% of the bike course so far.

A water tap is leaking at the rate of 25 mL every 20 seconds. How many litres of
water are wasted each day?
[3 marks]
Answer: 108 liters
Step-by-step explanation: There are 86,400 seconds in a 24-hour day. If 25 mL leak every 20 seconds, divide 86,400 by 20 (4,320), then multiply by 25 (108,000). There is 1,000 mL for every liter, so divide 108,000 by 1,000, and you will get 108 liters.

ms. wilson draws a model of the factorization of a polynomial with integer factors. her model is partially complete. which equation is represented by ms. wilson’s model? n2 3n 40
n²+13n+40,
This is why;
Observe only the right side. The number is (n+8)(n+5).
Let's elaborate on that using FOIL.
F = When we multiply the first two terms, n and n, we obtain n².
O = outer instructs us to multiply n by 5 to get n*5 or 5n from the outer terms.
I = inner instructs us to multiply the inner expressions 8 by 8 and n by n to obtain 8n.
Since 8 and 5 are multiplied by L, we obtain 8*5 = 40.
Add up the outcomes: n²+5n+8n+40 = n²+13n+40
Observe how the phrase is a little bit simplified by the combination of the like terms (5n and 8n).
This demonstrates how (n+8)(n+5) becomes n²+13n+40, becoming the correct response. For all values of n, none of the other options are valid equations;

)
The ordered pair for the greatest amount he can buy is (3.2, 12)
How to find the greatest cost of gas?He has $12 to put gas in his car. The gas costs $3.75 per gallon.
Therefore,
x = number of gallons of gasy = total cost of the gas.Hence, the total amount he has to spend is 12 dollars.
Therefore,
y = 3.75x
where
y = 12 dollars
Therefore,
12 = 3.75x
divide both sides by 3.75
12 / 3.75 = 3.75x / 3.75
x = 3.2
Therefore, the ordered pair for the greatest amount he can buy is (3.2, 12)

The Span of two noncollinear vectors is the plane containing the origin and the heads of the vectors.
Linear Span of vectors can be represented as
let [tex]x_{1} and x_{2}[/tex] be two non collinear vectors its span be written as [tex]x=a_{1} x_{1} +a_{2} x_{2}[/tex] where [tex]a_{1}, a_{2}[/tex] are arbitrary scalars.
Subspace of vectors : a subset A of a vector space V is called a subspace of V if A is itself a vector space under scalar multiplication and addition defined on V.
The Span of two vectors is a vector space containing two vectors. Hence the span is also a vector space . It is sufficient to notice that any two independent vectors from subspace can be the basis.
Zero vector is the linear combination of these basis vector.

subtract 3 on both sides
x = -3
x +4 = -3
subtract 4 on both sides
x = -7
3x = 0
divide 3 on both sides
x = 0
5x = 2
divide 5 on both sides
x = 2/5
x - 4 = 0
add 4 on both sides
x = 4
5x - 4 = 0
add 4 on both sides then divide both sides by 5
x = 4/5
2x + 4 = 5
subtract both sides by 4 then divide both sides by 2
x = 1/2
2x^2 = 9
square root both sides then divide both sides by 2
x = 3/2
5x - 1 = 2
add both sides by 1 then divide both sides by 5
x = 3/5
x + 3 = 65
subtract both sides by 3

The value of P(2 tails) is 37.5%, the correct option is B.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
The sample space= {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
Now,
The sample space for tossing a coin 3 times is {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}, where H represents heads and T represents tails.
To determine P(2 tails), we need to count the number of outcomes in which there are 2 tails, and divide that by the total number of outcomes:
Number of outcomes with 2 tails: There are three outcomes with 2 tails: TTH, THT, and HTT.
Total number of outcomes: There are eight outcomes in total.
P(2 tails) = number of outcomes with 2 tails / total number of outcomes = 3/8 = 0.375, which is equivalent to 37.5%.
Therefore, the probability the answer will be 37.5%.
