Answer:
313.6 sqft.
Step-by-step explanation
Decimal
First, convert the fractions into decimals to make it easier to multiply. 24 1/2 = 24.5. 12 4/5 = 12.8. 24.5*12.8 = 316.6.
Fraction
First, make the fractions into improper fractions. 24 1/2 = 49/2. = 12 4/5 = 64/5. 49/2*64/5 = 313 3/5 = 313 6/10 = 313.6.
The inequality is 7x + 21 
Step-by-step explanation:
<u>DATA:</u>
Let the number be x
Number times 7 = 7*x
Sum of a number times 7 and 21 = 7x + 21
Is at least 29
<u>INEQUALITY:</u>
7x + 21
<u>SOLVE:</u>
7x 
7x 
x 
Therefore, the inequality is 7x + 21

Answer:
x = 9±sqrt(7)
Step-by-step explanation:
3(x-9)^2 =21
Divide each side by 3
3/3(x-9)^2 =21/3
(x-9)^2 =7
Take the square root of each side
sqrt((x-9)^2) =±sqrt(7)
x-9 =±sqrt(7)
Add 9 to each side
x = 9±sqrt(7)
Answer:
The line represents a direct variation function.
Step-by-step explanation:
This line would cross the point (0, 0) making it a direct variation function.
We know the line would cross (0, 0) because the slope of the line is 2/3 (change in y over change in x, so 4-2 over 6-3 which simplifies to 2/3). From the point (3, 2), we can use the slope to calculate backwards to the origin.
2 wks = 38 cm SO
1 wk= 19 cm
19 cm a week
19 x 3 = 57
1/2 wk = 8 cm
57 + 8 = 65 cm in 3 1/2 weeks
