Answer:
The 3rd option
Step-by-step explanation:
Here you go :) . . . . ..
For scientific notation, you always want 1 digits in front of the decimal.
Ex) 7.39*10^5
Move the decimal point in between the 1 and 4, or 1 place to the left.
1.435
Since the decimal point was moved 1 place to the left, the exponent after 10 will be 1.
1.435*10^1
1.435*10^1 is your final answer.
1.435*10 is the same thing also.
Answer:
81 pounds
Step-by-step explanation:
Given that:
Peanut per pound = $6.75
Cashew per pound = $9.50
Let
Number of cashews sold = x
Number of peanuts sold = x + 32
Total sales made = $1,012.25
(Number of caahew sold * cost of cahew) + (Number of peanut sold * cost of peanut) = total sales made
(x * 9.50) + [(x + 32) * 6.75)] = 1012.25
9.50x + 6.75x + 216 = 1012.25
16.25x = 796.25
x = 796.25 / 16.25
x = 49
Number of peanuts sold = x + 32 = 49 + 32 = 81
Answer:
Jo started decelerating at the 10th minute
His average speed for the last 30 minutes of the journey is 4/30 km/minute
Step-by-step explanation:
To get what Jo did at 10 minute, we look at the graph.
At the 10th minute, we can see that we have a sharp turn from the top to the zero position at the 20th minute
so we can say that Jo started deceleration at the 10th minute
For the last 30 minutes of the journey, he travelled a distance of 4km
So, mathematically, his average speed will be;
Distance/ time = 4km/30 minutes = 4/30 km/minute
