Answer:
Step-by-step explanation:
Area of a trapezoid = h x (b1+ b2)/2
h= height
b1 and b2 are the bases
Answer:
Step-by-step explanation:
The Perimeter, P (feet) = 2 x Width(ft) + 2 x Length(ft)
P = 2*(3x-5) + 2*(2x+8)
P = 6x -10 + 4x + 16
P = 10x + 6 (in feet)
Total cost = P(ft)*(Cost ($/ft)) [The Cost is $5/ft]
Total cost = ((10x + 6)ft)*(5 ($/ft)) = <u>$(50x + 30)</u>
Since no value is given for x, this is the closest we can get to an answer.
[I notice that x must be greater than (1 2/3), otherwise, (3x-5) would be negative. Perhaps a negative distance is valid for the Klingons, but let's assume this is on Earth.]
I’m pretty sure the internet
Answer:
a. 281.25 grams
b. The 500 represent the original amount of aspirin.
c. 3/4 tells us what amount of the aspirin remains after every hour.
d's answer is in the picture. Just copy the line.
Step-by-step explanation:
A is the only part that needs any explanation.
Since the t represent hours, I'll subsititute t for 2.
500 * (3/4)²
<em>3/4 squared is 9/16.</em>
500 * 9/16
<em>Multiply 500 by 9 to get 4500.</em>
4500/16
<em>Simplify 4500/16 to 1125/4 (4 is canceled out.)</em>
1125/4
<em>Divide 1125 by 4 to get 281.25</em>
281.25
281.25 grams of aspirin will be in the patient body after two hours.
Answer:
I believe #20. is A
Step-by-step explanation:
because if you use distributive property and multiply the 5 to the () numbers you will get your original question.
Also, i cant see all of the options for #21.
