<h3>What is scientific notation?</h3>
Scientific notation is simply a way of expressing numbers that are too large or small to be written in decimal form.
It may be referred to as standard index form or scientific form.
From the information given, we have;
a. 0. 000003 is written in standard form as;
= 3 × 10^-6 × 3 × 10^6
= 3 × 10^-6 + 3
= 3 × 10^0
= 3
b. 56, 000, 000. 00 is written in standard form as;
= 5. 6 × 10^7 × 6 × 10^-7
= 33. 6 × 10^7 -7
= 33. 6 × 10^0
= 33. 6
c. 8. 0 × 10^-3 × 7. 2 × 10^5
= 57. 6 × 10^-3 + 5
= 57. 6 × 10^2
d. 4. 0 × 10^-3 × 4. 0 × 10^-4
= 4. 0 ^ -3 +(-4)
= 4. 0 × 10^-7
e. 7. 0 × 10^3 × 7. 0 × 10^4
= 7. 0 × 10^ 3-4
= 7. 0 × 10^-1
Thus, scientific notation is also referred to as standard form.

Answer:
Step-by-step explanation:
Given
Required
Determine the number of miles driven on the highway and on the city
Represent the gallons used on highway with h and on city with c.
So, we have:
---- gallons used
and
--- distance travelled
In the first equation, make c the subject
Substitute 10 - h for c in the second equation
Open bracket
Collect like terms
Make h the subject
Substitute 5 for h in
If on the highway, he travels 31 miles per gallon, then his distance on the highway is:
If in the highway, he travels 26 miles per gallon, then his distance on the highway is:
Answer:
His total gross pay for the week is $588.25.
Step-by-step explanation:
Consider the provided information.
Jarry has a salary of $43 per day and he worked for 4 days.
Thus, the salary of 4 days is:
4 × $43= $172
The average tips is 18% of his total gross food orders.
Last week he had total food orders of $2,312.5. Therefore, the total tips he received is:
Total tips he received is $416.25.
His total gross pay for the week = The salary of 4 days + Total tips he received.
His total gross pay for the week = $172 + $416.25
His total gross pay for the week = $588.25
Hence, his total gross pay for the week is $588.25.
Answer:
I second that,
Step-by-step explanation:
The minimum and maximum of the set alone is 25 and 60. The range of that 35. So, the number is not less than or more than 25 or 60.
The set in order:
25, 36, 48, 52, 60
The median is 48, so the number has to be less than 48. Let's see if the number may be less than 36.
36+48
84
42
So, the number is right between 36 and 48.
43.5×2
87
Let's subtract 48 from that
87-48
39
So, the mssing value is 39. Let's check.
25, 36, 39, 48, 52, 60
48+39
87÷2
43.5
So the missing value is 39.
