Answer:
44 ft
Step-by-step explanation:
Formula: L + L + W + W = P
16ft + 16ft + 6ft + 6ft = 44
Answer:
- a(x) = 20 + 0.60x
- domain [0, 50]; range [20, 50]
- maybe
Step-by-step explanation:
a) If x liters are removed from a container with a volume of 50 L, the amount remaining in the container is (50 -x) liters. Of that amount, 40% is acid, so the acid in the container before any more is added will be ...
0.40 × (50 -x)
The x liters are replaced with 100% acid, so the amount of acid that was added to the container is ...
1.00 × (x)
Then after the remove/replace operation, the total amount of acid in the container is ...
a(x) = 0.40(50 -x) +1.00(x)
a(x) = 20 +0.60x . . . . . liters of acid in the final mixture
__
b) The quantity removed cannot be less than zero, nor can it be more than 50 liters. The useful domain of the function is 0 ≤ x ≤ 50. (liters)
The associated range is 20 ≤ a ≤ 50. (liters)
__
c) As we found in part b, the amount of acid in the final mixture may range from 20 liters to 50 liters. So, the percentage of acid in the final mix will range from 20/50 = 40% to 50/50 = 100%. The mixture could be 50% acid, but is not necessarily.
The balloons of each color that Marty inflated are:
- Marty
- inflate
- red 271
- ballons
- Marty
- inflate
- red 380
- ballons
This is further explained below.
<h3>How many balloons of each color did Marty inflate?</h3>
Generally, the equation for the statement is mathematically given as
w= r+225
w - 225 = r
Therefore
w - 116 = b
Where
r + w + b = 1147
(w - 225 )+w +( w - 116)=1147
3w = 1147 + 341
w = 496
In conclusion, For Red
w - 225 = r
496 - 225 = r
r=271
Marty inflate red 271 ballons
For blue
w - 116 = b
496 - 116 =380
b=380
Marty inflate red 380 ballons

Answer:
C
Step-by-step explanation:
6(2m+5n)
12m+30n
Jacob had multiplied 6 to 2m right which is 12m but multiplied 6 and 5n wrong as he thought it was 11n yet it is 30n.
