Let r be the number of cards Ron has.
r + 2r + 4 = 97
3r + 4 = 97
3r + 4 - 4 = 97 - 4
3r = 93
3/3r = 93/3
r = 31
Ron has a total of 31 cards and Jason has a total of 66 cards.
Answer:
138.16 square feet
Step-by-step explanation:
The surface area of the cylinder consists of one rectangle and two circles.
1. The radius of the circle is 4 ft, then the area of the circle is
2. The width of the rectangle is 1.5 ft, the length of the rectangle is the circumference of the circle.
Find the circumference:
Hence,
3. The surface area of the cylinder is
Answer:
5, 9, 13, 17, 21, .....
Step-by-step explanation:
To generate the sequence, substitute n = 1, 2, 3, 4, ..... into the rule
a₁ = 4(1) + 1 = 4 + 1 = 5
a₂ = 4(2) + 1 = 8 + 1 = 9
a₃ = 4(3) + 1 = 12 + 1 = 13
a₄ = 4(4) + 1 = 16 + 1 = 17
a₅ = 4(5) + 1 = 20 + 1 = 21
The area of an ellipse is given by A = πab where a is half the major axis = 20/2 = 10 and b is half the minor axis = 10/2 = 5. Taking pi = 3.142, we have A = 3.142 x 10 x 5 = 157.079 m^2 = 157 m^2 to the nearest whole number. Therefore, the area of an ellipse with the major axis 20 m and the minor axis 10 m = 157 square meter<span> to the nearest whole number.</span>
The formula for this is 2
