In a circle with radius 2, an angle measuring pi/3 radians intercepts an arc. Find the
length of the arc in simplest form.
Answer:
2pi/3
Step-by-step explanation:
Using the formula s = r(theta), where s is arc length, r is radius, and theta is the central angle,
s = 2(pi/3)
s = 2pi/3
$300 at 2.5% for 16 months
Answer:
Total: $420 (growth of $120)
Step-by-step explanation:
Multiply $300 by 0.025 (2.5%) which is equal to 7.5. Then multiply that by 16 months which gives you $120 added to your $300.
by rounding each number to 1sf estimate the answers to 8.2*6.7/ 0.46
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]8.2\times \frac{6.7}{0.46}[/tex]
[tex]\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}[/tex]
[tex]=\frac{6.7\times \:8.2}{0.46}[/tex]
[tex]\mathrm{Multiply\:the\:numbers:}\:6.7\times \:8.2=54.94[/tex]
[tex]=\frac{54.94}{0.46}[/tex]
[tex]=100[/tex] (Round to 1 significant number)

six Notebooks cost 720 find the cost of 44 note books
Explanation:
720/6 = 120
44 x 120 = 5280
Answer:
$5280
Hope this helps!!!!!
Step-by-step explanation:
Cost of 6 notebooks = 720
Then, cost of 1 notebook = 720/6
Therefore, cost of 44 notebooks = 720/6 x 44
= 120 x 44
= 5,280
Therefore, the cost of 44 notebooks will be 5,280

So if he reads 147 pages of a book and he has completed 70% of the book how much would be left
Answer:
63 pages
Step-by-step explanation:
147/x=70/100
147=x(70/100)
x = 147/(70/100)
x = 210
210-147=63
Answer:
63 pages
Step-by-step explanation:
147 100
---- * ---- = 210 and then 210-147=63

A square plastic tarp has sides that are 7 meters long. What is the tarps area?
Answer:
49 square meters
Step-by-step explanation:
The formula for finding the area of a surface is [tex]area=length*breadth[/tex] Since the tarp is square, all of its sides have the same lengthSo the length equals the breadthThat means the area is [tex]area=(7meters)*(7meters)=49meters^{2}[/tex]А
Learning Task 4 : Do the following in your notebook.
A. Find the equation of the line given the graph.
Answer:
Question 3: y =x+2
Step-by-step explanation:
to find the equation use y=mx+c where m is the gradient/slope and c is the y intercept. In example 3, the y intercept is 2 so thats why the equation ends in +2, and the slope which is calculated by rise over run, is 2 over 2, or 1 so x doesnt need a coefficient.

What is the slope and y intercept for 14X - 7Y = 28
Answer:
y = 2x - 4 (the slope is 2 or 2/1 and the y-intercept is -4)
Step-by-step explanation:
Subtract 14x from both sides of the equation.
This should get you -7y = 28 - 14x.
Then you need to divide by -7 on both sides.
y = -4 + 2x is the result
which you can switch around if you like and get y = 2x - 4
Why is it essential to know how to solve Exponential equations in order to solve Logarithmic equations? (Make sure to fully explain).
Answer:
Because you need it for your later life and for your GCSES and if you dont want to fail then you will need it.
Step-by-step explanation:
Given an exponential equation in which a common base cannot be found, solve for the unknown. Apply the logarithm of both sides of the equation. If one of the terms in the equation has base 10, use the common logarithm. If none of the terms in the equation has base 10, use the natural logarithm.

The table shows the outputs y, for different inputs ,x
Input x: 3,7,11,15
Output y: 4,6,8,10
Part A: Do the data in this table represent a function? Justify your answer.
Part B: Compare the data in the table with the relation f(x) = 5x-21. Which relation has a greater value when x=11
Part C: Using the relation in part b, what is the value of x if f(x) =99
Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.
(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.
Part B: All we have to do is plug in 11 for x in the function given to find the answer:
In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.
Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:
