Donny drove 70 miles.
Since 60 miles per hour is 1 mile a minute so for in 45 minutes he drove 45 miles. After he drove for 50 miles for thirty minutes so in totally he drove 25 since 50 divided by two is 25.
57.55 in base 10 equal in base 2 is 57.55₁₀ = 111001.10001100110₂
Base 10:
It refers the decimal number system.
A number system which uses digits from 0 to 9 to represent a number.
Base 2:
It refers the Binary number system.
A binary number is defined as a number that is expressed in the binary system or base 2 numeral system. It describes numeric values by two separate symbols; 1 (one) and 0 (zero).
Given,
The base 10 number = 57.55
Now we have to convert it into base 2,
So, the conversion will follow the following step in image 1.
Write the Remainders from bottom to top
So, 57₁₀=111001₂
For Decimal Numbers
Refer image 2,
Write the Integer part from top to bottom
55₁₀ = 10001100110₂
Therefore,
57.55₁₀ = 111001.10001100110₂

Answer:
3 1/4 = 6,500 tons
Step-by-step explanation:
Answer:
y = tan(60°)x = (√3)x
Step-by-step explanation:
The usual translation between polar and rectangular coordinates is ...
... y = r·sin(θ)
... x = r·cos(θ)
If we solve the second equation for r, we get
... x/cos(θ) = r
Now, we can substitute this into the first equation with the result ...
... y = (x/cos(θ))·sin(θ) = x·tan(θ)
Our polar equation is θ = 60°, so we can substitute this value into the relation we have for x and y:
... y = x·tan(60°)
... y = (√3)x
_____
The portion of the line in the 3rd quadrant corresponds to r values that are negative. The given polar equation has no restriction against that.
2 Letters chosen among 6 with no repeat:
a) the first has 6 ways
the second has 5 ways
Then to choose 2 letters among 6, with no repeat, there are 6x5 = 30 ways
b) 3 numbers are taken from the digits 0 through 9 with repeats (total = 10)
the first has 10 ways
the second has 10 ways
the third has 10 ways
Then to choose 3 numbers among 10, with repeat, there are 10x10x10= 1000 ways
And the total serial numbers that can be generated is
30 x 1000 = 3000
