First round to 899 to 9 then count 5 decimal places left then put in scientific notation 9.0 x 10^-5
Answer:
0- 11 times
1,2,3,4,5,6,7,8,9- 12 times
Median is the number in the middle when all the numbers are put in order.
Let's do that first.
30 52 61 65 68 68 69 75 78 85
Now if there's 10 numbers, 2 numbers are in the middle.
By counting in 4 on both sides, we know the two numbers are both 68, so 68 is the median.
Answer:
24
Step-by-step explanation:
Objective: Circle Theorems. Understand that if two tangents of a circle are tangent to the same point, they are equal.
Using that this means that
DB equal CB.
Plug in line CB, 5x+20 to find the answer.
Answer:
102 cm2
Step-by-step explanation:
First you want to find the area of the entire rectangle by multiplying the 2 sides.
20cm x 6cm = 120
Then you want to find the area of the other two shapes (in this case the square and triangle). Also use the other sides to find the lengths of the triangle.
Square = 3 x 3 = 9
triangle = 6 x 3 = 18 / 2 = 9
So then all you have to do is subtract the squares and triangles area from the total rectangle.
120 - (9 + 9)
120 - 18
102 cm2
