Answer:
I think you might mean 5.784 and if that is the case it would be 5.8
Step-by-step explanation:
5.8 would be the answer because 8 is closer to 10 than 0 so 7 would be rounded up to 8
Answer:
1000g or 1kg
Step-by-step explanation:
Michelle took 1/5 of the pizza or it would be the same as: 1*3 / 5*3
= 3 / 15 of the pizza
Ethan yook 1/3 of the pizza or it would be the same as 1*5 / 3*5 = 5/15 of the pizza
We know that Ethan's pizza taken - Michelle pizza taken = 5/15 - 3/15 = 2/15
We are given that Ethan take 200g more than michelle so 5/15 - 2/15 = 3/15 of the pizza would be 200g
The total weight of the pizza would be 15/15
Because 3/15 = 200g
15/15 = 3/15 * 5 = 200*5 = 1000g or 1kg
Hope this helped :3
Answer:
6.9x
Step-by-step explanation:
2.7x + 3.2x + x = So you combine like terms. Since they all have x after them, they are all like terms so you can add them all together. x = 1
Therefore, your answer is 6.9x
Answer:
a. The initial value is 5575
b. The decay factor is 0.35 or 35%
Step-by-step explanation:
The decay equation is given as;
y = 5575(0.65)^t
Mathematically, a decay equation can be written in the form;
A = Ir^t
where A is the amount at a time, I
is the initial value and r represents the decay rate
a. So by comparing this with what we have, we can see that the initial value is 5575
b. We want to write the decay factor
We can rewrite the equation as;
y = 5575 (1-0.35)^t
where 0.35 = 35/100 which can be said to be 35%
