Answer:
W=5
Step-by-step explanation:
W=Width=Length + 1
L = Length
Area = Length * Width = 20
Area = L * W = L * (L+1) = 20
Distribute the L: L^2 + L = 20
Subtract 20 from both sides: L^2 + L -20 = 20-20
Simplify: L^2+L-20=0
Factor (L-4)(L+5)=0
Solve using the zero property: L-4=0, L=4 L+5=0, L=-5
The two options for length are 4 and -5. Only 4 will work for L since it cannot be negative. Width is Length + 1 = 5
<span>Let C represent the total cost (in dollars),
and let S represent the amount of sugar (in tons) transported
equation:
C(s) = </span><span>225s + 7500
</span><span>find the total cost to transport 11 tons of sugar.
</span>C(11) = 225(11) + 7500
C(11) = 2475 + 7500
C(11) = 9975

Answer:
- domain: x ≥ 0
- range: y ≥ 0
Step-by-step explanation:
The domain of a function is the set of x-values for which it is defined. The range of a function is the set of y-values the function produces.
<h3>Domain</h3>
The domain is the horizontal extent of the graph. This graph extends from x=0 toward x→∞. The domain is x ≥ 0. In interval notation, it is written [0, ∞).
<h3>Range</h3>
The range is the vertical extent of the graph. This graph extends from y=0 toward y→∞. The range is y ≥ 0. In interval notation, it is written [0, ∞).
Answer:
Step-by-step explanation:
2 coins are 0.25 = 50 cents. That leaves 92-50 = 42 cents and 5 coins to go.
The only way to get 2 cents is to have 2 pennies. That leaves 40 cents and 3 coins to go.
The only way to get 40 cents with 3 coins is 1 quarter, 1 dime, and 1 nickel.
So you have 3 quarters = 75 cents.
2 pennies = 2 cents.
1 dime = 10 cents.
1 nickel = 5 cents.
92 cents total and 7 coins.The only way to get 40 cents
"In three more years,Miguel's grandfather will be six times as old as Miguel was last year. When Miguel's present age is added to his grandfather's present age, the total is 68. How old is each one now?"
Miguel is 11 years old and his grandfather is 57 years old.
Last year Miguel was 10. In three more years his grandfather would be 60. 60/6=10. 11+57=68
