Answer: 740000000
Step-by-step explanation:
Answer:
0.000074
7.4×10−5
To write in standard notation, move the decimal point on
7.4
over as many times as the power of ten given.
Move to the left if the given power has a negative exponent
Move to the right if the given power has a positive exponent
Therefore:
7.4×10−5=0.000074
2. Kendall skated around the park 15 times in 25 minutes. If Kendall continues to skate at the same speed, how many times will he skate around the park in 48 minutes?
Answer:
28.8 rounds.
Step-by-step explanation:
Solve this using ratio
---------
15 rounds / 25 minutes
---------
Find out how many rounds per minutes: 25/15
1 round / (5/3) minutes
--------------
48 divided by (5/3) to get rounds now.
---> (48*3)/5 ---> 144/5 ---> 28.8
-----------------
28.8 rounds. So she only completed 28 full rounds as she didn't manage to complete 29 just yet.
A car salesman has 5 used cars for sale. They have a mean price of $7000. What is the total price of all 5 cars?.
Answer:
Step-by-step explanation:
5 used cars for sale. They have a mean price of $7000
. What is the total price of all 5
cars?
We are given total number of cars = 5 cars.
The mean of all of five cars = $7000.
Note: Total sum/value could be calculated by multiplying mean with the total numbers we have.
Total price = Mean × Total number of cars.
According to problem, mean is 7000 and total number of cars is 5.
Therefore, Total price of all 5 cars = 7000 × 5 = $35000.
We are given total number of cars = 5 cars.
The mean of all of five cars = $7000.
Note: Total sum/value could be calculated by multiplying mean with the total numbers we have.
Total price = Mean × Total number of cars.
According to problem, mean is 7000 and total number of cars is 5.
Therefore, Total price of all 5 cars = 7000 × 5 = $35000.

Raisins and peanuts, again! Sig’s class was told that their mixture is 80% raisins and 20% peanuts. In Sig’s sample, he counted 48 raisins. About how many peanuts would you expect to be in Sig’s sample?
Answer:
About 12 peanuts. This is 20% of 60 (nuts and peanuts together)
Step-by-step explanation:
Let there be a total of n pieces in the mixture. Then, focusing on raisins, 0.80n = 48, so that n = 60. Then the number of peanuts is 0.20(60) = 12.

1/6
Answer:
Mabey B) if someone else says other wise follow them.
The probability that she will go to softball practice in a striped jersey and green shorts is 1/6.
what is Probability?The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an event can be calculated using the following formula.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Given:
Meredith has a green, white, or striped jersey.
So, probability that she will go to softball practice in a striped jersey and green shorts
= 1/3 x 1/3
= 1/6
Hence, probability that she will go to softball practice in a striped jersey and green shorts is 1/6.
