Answer:
he will dig for 15 hours
Step-by-step explanation:
if a miner digs —90 feets in 6 hours
then he will dig –225 feet in x hours
—225 feet x 6 hours /—90 feet = 15 hours
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
Hey there!
In order to find out which one is greater, lets convert both of them into percents.
To convert a decimal into a percent, simply multiply the decimal by 100 or move the decimal two places to the right.
So!
0.086 × 100 = 8.6%
Now, we know that 0.086 is equal to 8.6% So, the correct answer is 86%
86% is greater than 0.086.
