Answer:
So scientific notation would be 5 x 10 ^7, and standard would be 50,000,000
Step-by-step explanation:
The 7 means you move the decimal to the right 7 times, meaning you add 7 zeros.
The table is attached.
A) The gasoline consume grows as the distance traveled increases. This means that the two quantities are directly proportional.
Therefore, the proportionality constant is given by:
k = gasoline / distance
= 2 / 40
= 0.05
We could have used also:
k = 3 / 60
= 0.05
In order to find the gasoline consumed, you need to multiply the distance by the proportionality constant:
30 × 0.05 =
1.555 × 0.05 =
2.75In order to find the distance traveled, you need to divide the gasoline consumed by the proportionality constant:
3.5 ÷ 0.05 =
70B) The function of the proportionality found is:
y = 0.05·x
where:
x = distance
y = gasoline
Therefore:
y = 0.05·110 = 5.5
Femi for a trip of 110 miles expects to use
5.5 gallons of gasoline.
Answer:
One order of fries costs 2
Step-by-step explanation:
She got 4.25 + two fries on Monday
She got 6.75 + one fries on Tuesday
Since she spends the same amount of money on lunch every day, both of the money that is spent must be equal.
Let f represent the cost of one order of fries, then equations can be written as follows:
4.25 + 2f (1)
6.25 + f (2)
Since both is equal:
→ 4.25 + 2f = 6.25 + f
→ f = 2
X= 2.5 that is the correct answer
