Answer:
1. Yes
2. Yes
3. No
4. No
Step-by-step explanation:
4(-2) +9>-19 Multiply 4 and -2
-8+9>-19 Add -8 and 9
1 > -19 1 is greater than -19
4(5) +9>-19
20+9>-19
29>-19 29 is greater than -19
4(-10) +9>-19
-40+8>-19
-32>-19 -32 is not greater than -19
4(-7) +9>-19
-28+9>-19
-19>-19 -19 is not greater than -19
Answer:
It will take 1 5/7 hours
Step-by-step explanation:
3/4 of an hour is;
3/4 * 60 minutes = 45 minutes
3 1/2 acres is done in 45 minutes
8 acres will be done in x minutes
Thus, mathematically;
3 1/2 * x = 8 * 45
7x/2 = 360
7x = 2 * 360
7x = 720
x = 720/7 minutes
Let us convert this to hours
That will be;
720/7/60 = 720/(60 * 7) = 720/420 = 12/7
= 1 5/7 hours
It is a geometric sequence because it has a ratio 12/4=3, 36/12=3
The most basic example of the binomial theorm is the formula for the square of x + y: the binomial coefficients 1, 2, 1, appearing in this expansion correspond to the second row of Pascal's triangle
Answer: $8.88
Assuming its 8:00am to 4:15pm and took a 1 hour break then he worked for a total of 7 hours and 15 minutes. In decimals that would be 7.25 hours. We want to find how much he makes in 1 hour. So, because we want to find 1 hour we divide the hours by 7.25 and the money by 7.25.
64.38 / 7.25 = 8.88.
There for, he makes $8.88.
