To round a number to the nearest hundred, we count two places to the left of the decimal point, or from the last digit if the number is a whole number.
If the second digit from the last digit is upto 5, we add 1 to the preceding digit and we complete the last two numbers with zeros.
Therefore, any number from 11,950 to 12,049, will result to 12,000 when rounded to the nearest hundred.
Answer:
The combination of linear equations is
x+y = 75
y+15 = x
Step-by-step explanation:
x = representation of minutes Jack jogs
y = representation of minutes Jack bikes
Sum of 75 minutes for biking and jogging
x+y = 75
The combination of linear equations is
x+y = 75
y+15 = x
He bikes for 15 minutes higher than he jogs
y+15 = x
Answer:
a = 105 in²
Step-by-step explanation:
Front and back, triangles
a = 2 * (1/2)(5 * 6)
a = 30
Sides, squares
a = 3 * (5 * 5)
a = 75
Total
a = 30 + 75
a = 105 in²
