Answer:
Step-by-step explanation:
The diameter of a tire is the distance across the tire through the center. Since tires are circular, you can find the circumference of the tire from the diameter. The circumference represents the distance the tire travels when it makes one revolution. If you know the number of inches in a mile and the circumference, you can find the number of times the wheel turns per mile.
First, measure the diameter of the tire in inches.
Secondly, multiply the diameter by pi, which is approximately 3.1416, to find the tire circumference. For example, if the tire has a 20 inch diameter, multiply 20 by 3.1416 to get 62.83 inches.
Answer: 11/16
<u>Turn 1 7/8 into an Improper Fraction</u>
Multiply 1×8 and get 8. Now add 7 and get 15.
1 7/8 = 15/8
<u>Turn 2 8/11 into an Improper Fraction</u>
Multiply 2×11 and get 22. Now add 8 and get 30.
2 8/11 = 30/11
<u>Do Keep Change Flip</u>
Keep: 15/8
Change ÷ into ×
Flip: 30/11 into 11/30
Your New Problem: 15/8×11/30
<u>Multiply</u>
15/8×11/30=165/240
<u>Simplify</u>
165/240÷15/15=11/16
Answer:
vertex is the (maximum value)
function is increasing (when x<-1)
function is decresing (when x>-1)
domain of the function is (all real numbers)
range of the function is (all numbers less than or equal to 0)
Step-by-step explanation:
just did the assignment.
4x + 7y = 60
-4x + 7y = -4
------------------add
14y = 56
y = 56/14
y = 4
4x + 7y = 60
4x + 7(4) = 60
4x + 28 = 60
4x = 60 - 28
4x = 32
x = 32/4
x = 8
so ur solution is : (8,4)
Answer:
98450 > 2560 * (1.5)^(t/2)
Step-by-step explanation:
We are told that there are 2560 cells in the test tube. Then they tell us that every 2 minutes, the number of cells increases by 50%. At 98,450 cells, the test tube will explode. Since Louie got to the lab before the tube exploded, 98,450 is greater than. On the other side of the inequality, we get 2560 times 1.5, because it is increasing by 50%. Then we put 1.5 to the power of t/2 because it grows by 50% every two minutes. The end result is 98450 > 2560 * (1.5)^(t/2). Hope this helps.
