Idk I’m really srry about it
Answer:
3159.853 km
Step-by-step explanation:
The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:
9984670 = (x)(x) which rearranges to 998470 = x^2
get the square root and you get:
x = 3159.853 km
for every 1/10 second it travels 21.98 inches
for a full second it travels 21.98 x 10 = 219.8 inches
for 1 minute it travels 219.8 x 60 = 13188 inches / 12 = 1099 feet per minute
1099*60 = 65940 feet per hour
5280 feet per mile
65940/5280 = 12.488= 12.5 miles per hour
10x+20y=150 is the equation I don't quite understand how she would have money left because she spend $150 for her t-shirts and jeans.
