What is 4L 710mL - 2L 690 mL

Answers

Answer 1

Answer:

Answer:

$2L$ and $20mL$ , or $2020mL$

Step-by-step explanation:

We can solve this problem in two ways:

Making operations with liters and milliliters separately
Converting all measurements to the same unit and subtracting

With the fist way:

$4L-2L=2L$

and

$710mL - 690mL= 20mL$

anwer is $2L$ and $20mL$ wich is the same as $2020mL$

With the second way:

Fist conveting everything to mL $4L =4000mL$

thus:

$4L+710mL =4000mL+710mL=4710mL$

and $2L=2000mL$

thus:

$2L+690mL=2000mL+690mL =2690mL$

and then subtracting the two values:

$4710mL - 2690mL= 2020mL$

Answer 2

Answer:

4L - 2L = 2L

710mL - 690mL = 20mL

your final answer is... 2L 20mL

Is there 2 square numbers that add up to 65

Answers

$1^(2) + 8^(2) =1+64=65$

Im thinking there are two ways....
8² +1² = 8 * 8 + 1 *1 = 64 + 1 = 65
7² + 4² = 7 * 7 + 4 * 4 = 49 + 16 = 65

A bull’s-eye with a 4-inch diameter covers 20 percent of a circular target. What is the area, in square inches, of the target?

Answers

Area of a circle is found using the formula: Area = π * r^2

Using 3.14 for π

Area of the bull'e eye = π * 2^2 = 4π = 4 * 3.14 = 12.56 square inches.

This is 20% of the entire target.

To find the area of the entire target, divide the area of the bull's eye by the percentage:

Area = 12.56 / 0.20 = 62.8 square inches.

Round the answer as needed.

Answer:

Area of target = 62.8 inch²

Step-by-step explanation:

A bull’s-eye with a 4-inch diameter covers 20 percent of a circular target.

Diameter of bull's eye = 4 inch

$\texttt{Area of bull's eye = }(\pi* 4^2)/(4)=12.56inch^2$

Given that bull’s-eye covers 20% of circular target.

$\texttt{Area of bull's eye = }(20)/(100)* \texttt{Area of target}\n\n\texttt{Area of target}* 0.2=12.56\n\n\texttt{Area of target}=(12.56)/(0.2)=62.8inch^2$

Area of target = 62.8 inch²
