Step-by-step explanation:
If she had $6.95 and she owed her friend 5 dollars that means the friend gave her 5 dollars. So $6.95 + $5 = to $11.95. So that's how much the snack cost
We know that
area of rectangle A=L*W
A=L*W------> solve for W
W=A/L
case 1) L=5 cm A=31.25 cm²
W=A/L-----> 31.25/5----> W=6.25 cm
the answer part 1) is W=6.25 cm
case 2) L=9.25 cm A=55.5 cm²
W=A/L----->55.5/9.25----> W=6 cm
the answer part 2) is W=6 cm
case 3) L=7.5 cm A=48.75 cm²
W=A/L-----> 48.75/7.5----> W=6.5 cm
the answer part 3) is W=6.5 cm
case 4) L=5 cm A=44 cm²
W=A/L-----> 44/5----> W=8.8 cm
the answer part 4) is W=8.8 cm
Answer:
(B)72 fluid ounces
Step-by-step explanation:
To convert cups to fluid ounces, Sari wrote the equivalent ratios.
Let the question mark be represented by x.
We then have:
We conclude that there are 72 fluid ounces in 9 cups.
increasing 20 to 40 is the same as increasing 20 by 20 (or itself), so it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by 1/2 or by 20. So it is a 50% increase.
when going from 20 to 40, the number is being doubled, and when youre going from 40 to 20 you are cutting the number in half.
hope this helped:)
