Answer:
its {0,1,2,3,4,5......}
Step-by-step explanation:
Answer:
a = 
Step-by-step explanation:
4a -16 = a - 15
both left and right -a
then
4a - 16 -a = a - 15 -a
then
4a -a -16 = a -a -15
then
3a -16 = -15
both left and right + 16
then
3a -16 + 16 = -15 + 16
then
3a = 1
both left and right ÷3
then
3a ÷ 3 =1 ÷ 3
then
a =
Answer:
6x+20 or 2(3x+10)
Step-by-step explanation:
Six friends went to a basketball game and four people paid $5 extra for a t-shirt. To find the total cost, multiply 6 by x and 4 by 5 this add them together:
6*x+4*5
6x+20, If needed you can factor this expression to:
2(3x+10)
Option D : 54 is the range of the distribution
Explanation:
The given distribution is 21, 32, 49, 67, 75
The range of the distribution is the difference between the highest value and the lowest value in the distribution.
From the given data, we can see that,
Highest value = 75
Lowest value = 21
The range can be determined by subtracting by the highest value and the lowest value.
Thus, we have,
Range = Highest value - Lowest value
Range = 75 - 21
Range = 54
Thus, the range of the given distribution is 54.
Hence, Option D is the correct answer.
L = 2 W
B = L x W = 2 W²
Side Area = 2 W H + 2 L H = 2 H ( W + L ) = 6 H W
V = 2 W² H = 10
H = 5 / W²
Cost = 15 * 2 W² + 9 * 5/W
= 30 W² + 270/ W
C ` = 60 W - 270 / W²
= ( 60 W² - 270 ) / W² = 0
60 W² = 270
W ² = 270 : 60
W² = 4.5
W = √ 4.5 = 2.12
Cost (min) = 15 * 2 * 4.5 + 30 / 2.12 = 135 + 14.15 = $149.15
Answer: The cost of materials for the cheapest such container is $149.15.
