Answer:
1.5
Step-by-step explanation:
a : b = 1 : 12/5
Area of a circle = πr²
Where : = π = pi = 22/7
R = radius
Let the radius of circle a = 1
Area of circle A = 1π
Radius of circle A = square root of 12/5 = 1.5
The circumference of a circle = 2nr
n = 3.14
circumference of circle A = 2 x n x 1 = 2n
circumference of circle B = 2 x n x 1.5 = 3n
ratio of circumference = 3n / 2n = 1.5
A geometric sequence is where you multiply by a constant number to get the next number.
An arithmetic sequence is where you add by a constant number to get the next number.
In the sequence 2, 10, 50, 250, the difference between the numbers are different, but when you multiply each number by 5, you get the next number.
This means that this is a geometric sequence.
The next term would be 250 x 5 which is 1250.
H. 11/40 is the answer.
Showing your work: Total number of players is 80. 22 play Speed Karts. 22/80 simplified by dividing by 2 is 11/40.
A rhombus<span> is </span>similar<span> to a </span>square<span> in two ways: both have two pairs of parallel sides and both have four equal sides. A </span>rhombus<span> is different from a </span>square <span>because it does not have four right angles. All squares are also rhombuses.</span>
Remember:
-When multiplying numbers with decimals just forget about the decimals for a second and pretend you are multiplying a 3 digit number times a 2 digit number.
-one digit at a time. Multiply going from right to left.
First:
-Multiply the 3 with the top numbers.
-Pretend you are seeing this:
5.72 (3)
- 2*3=6. 7*3=21. (carry the 2). 5*3 +2=17. (leave the 1).
Second:
-write below and move a digit to the left.
-pretend you are seeing this: 5.72(6).
- 2*6 =12. (carry the 1). 7*6 +1=43. (carry the 4) 5*6+4=34. (leave the 3).
Third: since in the problem the decimal is placed in the hundredths only once, place the decimal in the hundredths as your solution.
Your solution should be 360.36
