Answer:
4 times
Step-by-step explanation:
Area of circle A
[tex]\pi \times {r}^{2} = area \: of \: a \: circle \\ \pi = 3.14 \\ 3.14 \times {8}^{2} \\ 3.14 \times 64 = 200.96 \: {cm}^{2} [/tex]
Area of circle B
[tex]\pi\times 4 (because \: radius \: is \: the \: half \: of \: diameter) \\ 3.14 \times 4 square = 50.24\: {cm}^{2} [/tex]
How many times larger is the area of circle A than circle B
[tex]200.96 \div 50.24 = 4[/tex]
therefore circle A is 4 times larger than circle B in accordance with its area

How do you get 60cm2 in question 1?
Answers
Answer:
Step-by-step explanation:
4*2=8, thats one rectangle (side)
8*2 is 16, thats TWO rectangles (sides)
7*4=28, thats one rectangle (front)
28*2=56, thats TWO rectangles (front and back)
7*2=14, thats one rectangle (top)
14*2=28, thats TWO rectangles (top and bottom)
add all of these surface areas together
TWO rectangles + TWO rectangles + TWO rectangles
28+56+16=100
As you can see, the 60cm2 is incorrect. 100cm2 is the real surface area of the shape

1. What the error was
2. How can U check ur answer
Answers
Answer:
The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8
The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2
You can check your answer by plugging in your answer to the variable and making sure both side equal each other
Step-by-step explanation:
The first one: the 5 should be - from both side so you get k=-8
The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2
Remember you always want to get the variables by themselves.

[tex]x=61[/tex]
Step-by-step explanation:
We can find the angle directly above the [tex]2x+8[/tex].
We know that because they both lie on a straight line, the other angle is [tex]180-(2x+8)=172-2x[/tex].
Aha! We have a path to the solution!
[tex]172-2x=x-11[/tex] because of the parallel line angle theorem(I forget what it's called).
We then add [tex]2x[/tex] and [tex]11[/tex] to both sides to get [tex]183=3x[/tex].
Lastly, we divide by [tex]3[/tex] to get [tex]61=x[/tex].
So, [tex]\boxed{x=61}[/tex] and we're done!

A cashier has a total of 98 bills, made up of fives and fifties. The total value of the money is $2605. How much of each kind does he have?
He has ___ fives and ___ fifties.
Answers
Answer:
Step-by-step explanation:
x= number of fives
y= number of fifties
x+y=98
5x+50y=2605
Solving through elimination...
5x+5y=490
(5x+50y)-(5x+5y)=2605-490
45y=2115
y= 47
x+47=98
x=51
Which means he has 51 fives and 47 fifties
