What is the formula for area of a rectangle and triangle?
The area of a rectangle is found by multiplying the length and width.The area of a triangle is found by taking half the base multiplied by the height.
The formula for this is A = lw, where A is the area, l is the length, and w is the width. For example, if the length of the rectangle is 10 cm and the width is 5 cm, then the area of the rectangle is A = 10 * 5 = 50 cm2.
The area of a triangle is found by taking half the base multiplied by the height. The formula for this is A = 1/2bh, where A is the area, b is the base, and h is the height. For example, if the base of the triangle is 10 cm and the height is 5 cm, then the area of the triangle is A = 1/2 * 10 * 5 = 25 cm2.

The range of the function f(x)=[x+3]-5 is
A) [-5,∞)
B) (-5,∞)
C) [3,∞)
D) (3,∞)
The range of a function is the set of all possible outputs (y-values) for a given input (x-value).
Given the function f(x) = [x+3]-5, we can see that the function first adds 3 to x and then subtracts 5. The square bracket notation around (x+3) indicates that the function is taking the greatest integer less than or equal to (x+3).
For any input x, the output of the function will always be the greatest integer less than or equal to (x+3) - 5. Therefore, the output of the function is always an integer less than or equal to -2.
So the range of the function is [-5, -2] U (-2, ∞)
Option A) [-5,∞) is incorrect as the range starts with -5 but the function output is always less than or equal to -2.
Option B) (-5,∞) is incorrect as the function output is always less than or equal to -2.
Option C) [3,∞) is incorrect as the function output is always less than or equal to -2.
Option D) (3,∞) is incorrect as the function output is always less than or equal to -2.
The correct answer is (-2, ∞)

Let sales units of Pecan = p and sales units of chocolate = c
Equations:Equation 1: 8p + 6c = 182
Equation 2: 7P + 12C = 274
Multiply Equation 1 by 2:
Equation 3: 16p + 12c = 364

Sue take two random bicuit from the tin. Work out the probability that the two bicuit are not the ame type
So, the probability that the two biscuits are not the same type is 0.15 or 15%.
To find the probability that the two biscuits are not the same type, we need to calculate the probability that Sue takes one biscuit of each type.
First, we will calculate the probability that Sue takes one plain biscuit, one chocolate biscuit, and one currant biscuit.
The probability of Sue taking one plain biscuit is 12/20, since there are 12 plain biscuits out of a total of 20.
The probability of Sue taking one chocolate biscuit after taking a plain biscuit is 5/19, since there are now 5 chocolate biscuits out of 19 remaining.
The probability of Sue taking one currant biscuit after taking a plain and chocolate biscuit is 3/18, since there are now 3 currant biscuits out of 18 remaining.
To find the overall probability that Sue takes one biscuit of each type, we multiply the individual probabilities together:
P = (12/20) * (5/19) * (3/18) = 0.15
So, the probability that the two biscuits are not the same type is 0.15 or 15%.

What is 3 with an exponent of 0?
When a number has an exponent of 0, it means that the number is being multiplied by itself 0 times. In other words, it is multiplied by 1.
To determine this:
In the case of 3 with an exponent of 0, it would be represented as 3^0. To calculate the value, we would take 3 and multiply it by 0 times.
3 x 1 = 3
So, 3 with an exponent of 0 is equal to 3.
It is important to note that any number with an exponent of 0 will always equal 1, except for 0 which will always be 0. This is because any number multiplied by 1 is itself, and 0 multiplied by any number is always 0.

If 750ml of paint covers an area of 12 m2, what area (in m2) will 1.6 litres of paint cover?
Answer: To find the area that 1.6 litres of paint will cover, we can use the unit rate. The unit rate is a way to compare different quantities by finding how much of one quantity corresponds to one unit of another quantity.
We know that 750ml of paint covers an area of 12 m2, this means that the unit rate of paint:area is 750ml:12m^2
We can use this to find the area that 1.6 litres of paint will cover.
First we should convert the 1.6 litres of paint to milliliters, since we have the unit rate in ml:
1.6 litres = 1.6*1000 ml = 1600 ml
Now we can use the unit rate to find the area that 1.6 litres of paint will cover:
Area = (1600 ml paint) * (12 m2/750ml paint) = 21.333 m2
So, 1.6 litres of paint will cover approximately 21.333 m^2
Note that you could also use the proportion (750ml/12m^2) = (1600ml/x) to find the value of x.

The formula is 0 = 2 + 3x² - 5x.
We obtain = 3x² - 5x + 2 = 0 by arranging the equation in the form of the general equation ax2 + bx + c = 0.
The leading coefficient is a, the intermediate term's coefficient is b, and the constant term is c.
We may locate the equation's roots or the parabola's vertex by knowing the values of a, b, and c.
After comparing the equation to the general equation, the coefficient and constant term values are as follows.
A = 3
B = -5
C = 2
So, now both the polynomial and the coefficients are available.
