It costs $0. 50 per square yard to waterproof canvas. What will it cost to waterproof a canvas truck cover that is 15' x 24'
It will cost $10.00 to waterproof a canvas truck cover that is 15' x 24'.
To find this, we need to first convert the dimensions of the canvas truck cover from feet to yards, since the cost is given per square yard. 15' x 24' = 180 sq ft. 1 sq yard is equal to 9 sq ft, so 180 sq ft/9 sq ft/yard = 20 sq yard. Then we multiply the square yards by the cost per square yard to find the total cost:
20 sq yard x $0.50/sq yard = $10.00.It's important to note that the measurements of the canvas truck cover are given in feet and the cost is given per square yard. It's important to convert it to square yards to match the unit of measurement and calculate the cost.

Sue has 20 biscuits in a tin.
There are: 12 plain biscuits
5 chocolate biscuits
3 currant biscuits
Sue takes two random biscuits from the tin.
Work out the probability that they are not the same type.
Answer:
The probability that the two biscuits were not the same type is 58.4%.
How much is the probability that the two biscuits were not the same type?
The probability that they are different is the opposite of the probability that they are the same.
The probability that they are the same is:
⇒ P(plain, plain) = (12/20) (11/19) = 132 / 380
⇒ P(chocolate, chocolate) = (5/20) (4/19) = 20 / 380
⇒ P(currant, currant) = (3/20) (2/19) = 6 / 380
⇒ P(same) = 132/380 + 20/380 + 6/380
⇒ P(same) = 158/380
⇒ P(same) = 79/190
Therefore, the probability that they are different is:
⇒ P(different) = 1 − 79/190
⇒ P(different) = 111/190
⇒ P(different) ≈ 58.4%
What does probability mean?
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
For which function is the average rate of change over the interval 1 < x < 5 greater than the average rate of change over the same interval for the function g(x) = 1. 8x2?
The function g(x) = 1. 8x2 greater than the average rate is k(x) = 2x^2
How to calculate average rate?
The average rate is a measure of how quickly a quantity changes over a specific period of time. It can be calculated by dividing the change in the quantity by the change in time. The formula for calculating the average rate is:
Average rate = (final value - initial value) / (final time - initial time)
Given a function y, the average rate of change S of y = f(x) in an interval (Xs, Xf) will be given by the following equation:
In this problem, we have that:
Interval (1,5), so
Then
S = f(5) - f(1)/4
All options are compared to g(x).
g(5) = 1.8*(5)^2 = 45
g(1) = 1.8*(1)^2 = 1.8
An average rate of change greater than 10.8.
D.=k(x) = 2x^2
k(5) = 2*(5)^2 = 50
k(1) = 2*(1)^2 = 2
Greater than 10.8, this is the answer.
Hence, The function g(x) = 1. 8x2 greater than the average rate is k(x) = 2x^2

Answer:
b. ±√60
Step-by-step explanation:
You want to know the solution to x² = 60.
SolutionIn general, the process of solving for a variable's value requires you to "undo" what is done to the variable. This generally means you use inverse operations. The inverse of the squaring operation is the square root operation.
Taking the square root of both sides, we get ...
√(x²) = √60
|x| = √60 . . . . . . simplify the left side
x = ±√60 . . . . . . . write the equivalent without the absolute value bars
__
Additional comment
As with any operation performed on an equation, it must be done to both sides of the equal sign.
You will get a ±(radical) result whenever you take an even-index root: square root, fourth root, sixth root, and so on. Odd-index roots will have the same sign as the value under the radical.
√64 = ±8

Two piecewise functions are shown below. What is the value of 3h(2) + 4g(1)?
Answer: In order to calculate the value of 3h(2) + 4g(1), we would need to know the specific functions h(x) and g(x) that you are referring to. Without more information, it is not possible to determine the value of the expression.
Typically, piecewise functions are defined by several different expressions, each defined over a different interval of the input variable x. To evaluate a piecewise function at a specific value of x, we must first determine which interval that value of x falls into, and then use the corresponding expression for that interval to find the output value.
Are you able to provide the piecewise functions, or are you just using them as an example?

What is sine rule?Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
The formula for sine rule is sinA/a=sinB/b=sinC/c
Given that, an interior designer plans to use triangular tiles that are 8 cm×9 cm×13 cm for a backsplash.
Using cosine rule, we get
9²= 8²+ 13²- 2(8)(13) cos θ (angle opposite 9 cm side.)
81=64+169-208 cos θ
81-233=-208 cos θ
-208 cos θ=-152
cos θ=-152/(-208)
cos θ=0.7307
θ=43.7°
Using sine rule,
The formula for sine rule is sinA/a=sinB/b=sinC/c
sinA/8 =sin43°/9=sinC/13
sinA/8 =0.7307/9
sinA/8=0.0811
sinA=0.6495
A=40.5°
So, ∠A+∠B+∠C=180°
40.5°+43.7°+∠C=180°
∠C=95.8°
