Answer:
Step-by-step explanation: The area of the bedroom is
A=7yd^2
The total cost is the sum of the price rates times this area.
C=A•($21+$5)/yd^2
where C is total cost.
C=7yd^2•($21+$5)/yd^2
C=$182
Please write that as 4.321 × 10^(−4). The " ^ " indicates exponentiation and the parentheses help make clear that your exponent here is a negative one.
Rewrite 4.321 × 10^(−4) by moving the decimal point 4 places to the left:
0.0004321
The equation only is true for objects with negligible air resistance. A feather does not have this property.
Using the equation shown:
50 = -16t^2
t^2 = 50/16 = 3.125
t = sqrt(3.125) = 1.77 seconds
Substituting 1000 for A, we have 1200R+700,000=1,000,000. Subtracting 700,000 from both sides, we have 1200R=300,000. Dividing by 1200, we see that R=250.
Answer:
113.17
Step-by-step explanation:
add them but line up the decimal. remember smallest number first. You know actually it don't matter
