Answer:
yes your math seems about right but wait for someone else to respond also because im not completely sure
Step-by-step explanation:
Answer:
We find 3/4-5/24 = 0.54166666666 and try 2/7 x 6/8 = 0.21428571428
this is 0.069 too much we look at this as a fraction = 0.07 which is 1/10 approx of the 6/8. we then reapply 7/9 x 2/7 x 3/3 = 0.2
So we went up by 1 and can show another
2/7 x 7/10 = 2.0
So to 1dp there is lots of fractions including 2/7 x 7/9 = 2.0
But for three fractions that multiply together we can chose 5/7 x 2/6 x 6/6 = 2.0 As 5 x 2 x 6 = 60 and 60/360-102 = 60/258 = 0.20 and divided 198 =numbers 8 and 1/3 work with = 1.98/8.3 = 2.38554
We try again 1.68/8.3 = -0.2024 = 2/8 x 8/10 = 0.2
The balance is 1.3/2 x 0.8/2 = 0.65 x 0.333 = 13/20 x 1/3
3/5 x 1/3 = 0.2
Answer:
There were 30 children and 10 adults.
Step-by-step explanation:
Since they sold tickets to adults and childrens, the sum of those tickets must be equal to the total tickets that were sold, so we can mount our first equation as shown below:
adult + children = 40
Each adult ticket costs $9 and each children costs $5 and the total recieved was $240, therefore:
9*adult + 5*children = 240
We can mount the following equation system:
adult + children = 40
9*adult + 5*children = 240
We will multiply the first equation by -5 and sum both equations:
-5*adult -5*children = -200
9*adult + 5*children = 240
4*adult = 40
adult = 40 / 4
adult = 10
adult + children = 40
children = 40 - adult = 40 - 10 = 30
There were 30 children and 10 adults.
With no limiting factors to the growth of the plants, the number of months have passed since the plants were first introduced is 23.1.
<h3>What is an exponential function?</h3>
Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.
A type of plant is introduced into an ecosystem and quickly begins to take over.
A scientist counts the number of plants after m months and develops the equation to model the situation, which is given as,
Most recently, the scientist counted 138 plants.
Taking log both sides of the equation,
Thus, with no limiting factors to the growth of the plants, the number of months have passed since the plants were first introduced is 23.1.
