Answer:
6; 22; 20 (ft.)
Step-by-step explanation:
1) if the length of the each side are: n; 4n-2 and 4n-4, then the expression of the perimeter can be written: P=n+4n-2+4n-4 or P=9n-6.
2) if according to the condition perimeter is 48 (ft.), then
9n-6=P; ⇔ 9n-6=48; n=6.
3) if n=6, then the required lengths of the sides are:
n=6 (ft.);
4n-2=22 (ft.);
4n-4=20 (ft.)
-8+b2-(5+b2). Since the - is outside the paranthesis the signs inside change: -8+b2-5-b2. -8-5=-3, b2-b2=0. Your answer: -3 :)
Answer:
34
Step-by-step explanation:
13-(-21) = 13 + 21 = 34
Answer:
94 seats
Step-by-step explanation:
We solve using Arithmetic sequence formula
an = a + (n + 1)d
Where
a = First term = 49
d = Common difference = 52 - 49 or 55 - 52 = 3
n = 16th row
Hence,
a16 = 49 + (16 - 1)3
a16 = 49 + (15 × 3)
a16 = 49 + 45
a16 = 94
Therefore, the number of seats on the 16th row is 94 seats
Answer:
For 12 people, the identical recipe that would serve this amount would be 2 liters of lemon-lime soda, 1 pints of sherbet, and 3 cups of ice.
To figure out the corresponding proportion from 24 servings to 12 servings, first we divide 24 by 12, which is 2. The number 2 represents how many times bigger the original recipe is to the smaller 12 servings version, which mean the 24 people version would be twice as big compared to the 12 people serving. So all we have to do to the recipe is divide it in half. And so 4 liters divided by 2 is 2 liters of lemon-lime soda, 2 pints of sherbet becomes 1 pint, and 6 ice cups turns into 3 cups of ice.
