If 60 U.S. dollars represwnt 50 euros, we will add.
80 euros represent 90 dollars because: there are 10 more euros than dollars.
Hope this helps!
Answer:
x = 1, y = 2
Step-by-step explanation:
x + y = 3 => 2x + 2y = 6
2x + 3y = 7
-)2x + 2y = 6
=> y = 1, x = 2
Answer: 21.9 pounds of his weight is made up of fat.
Step-by-step explanation:
The total weight of the individual is 129 pounds. The individual has a body fat percentage of 17.7%.
Therefore, the number of pounds of his body that is made up of fat would be
17.7/100 × 129 = 0.177 × 129 = 21.93 pounds.
Approximating to the nearest tenth, it becomes 21.9 pounds.
The formula for the volume of a cylinder is pi * radius squared * height, or πr^2h.
To find the radius of the cylinder, take the given diameter (60 cm) and divide it by 2. 60 / 2 = 30 cm.
Now we need to either find the height in centimeters or find the radius in meters. Because a centimeter is 1/100 of a meter, we multiply the radius by 100 to get the radius in meters.
We also must square the radius. So 30 cm multiplied by itself equals 900 cm.
Radius: 900 / 100 = 9 m
We have to square the radius before plugging it into the equation because it would mess up the numbers if we didn't (0.3 m squared is 0.09 m, which is very small).
Now we can plug these values into the formula for the volume of a cylinder.
π * r^2 * h = π * 9 m * 1.7 m = ~48.066 cubic meters
Rounded to two decimal places is 48.07 cubic meters.
The volume of the tree trunk is about 48.07 cubic meters.
