Answer:
25cm
Step-by-step explanation:
The radius of circles is 7cm,24cm
Area of smaller circle is πr
2
⟹π×7
2
⟹49π
Area of Larger circle is πr
2
⟹π×24
2
⟹576π
Area of required circle ⟹576π+49π
⟹625π
Radius of circle is given by
625
=25
Answer:
4,000
Step-by-step explanation:
Rounding rule:
"4 or less, round down / keep the same."
"5 or more, round up."
Since the hundreds place has a 3, that means we round the thousands place to 4,000, because the hundreds place is lower than 5.
Answer: y = -5x + 6
Step-by-step explanation:
First, we need to find the slope, which would be m in the equation. To find m, we can use the formula called "rise over run". Here's the formula: 
So, to use this formula, you pick two points from the line that you're given and solve for m.
Let's use the points (1,1) and (0,6). x1 would be 1, x2 would be 0, y1 would be 1, y2 would be 6


So, the slope is -5
Then, we need to find the y intercept, which would be b in the formula.
We can see that the point where the line meets the y axis is at (0.6), so the y intercept would be 6.
Now let's put everything together:
y = mx+b
y = -5x + 6
Cos 17pi/4 = cos pi/4 because 17pi / 4 = 16pi/4 + pi/40
cos pi/4 = 1 / sqrt2 or 0.7071 to nearest 10,000 th
Answer:
A
Step-by-step explanation:
formatting is so bad lol
but yeah its the first one because for independent events, the probably of a and b is the product of both probabilities, just like how 0.3*0.4=0.12
