Answer:
b= $3.99×2 + $2.50= $10.48
Step-by-step explanation:
We have the following unknowns:
p: number of people in the club
f: ounces of fruit punch
c: ounces of cheese
b: budget in dollars
We know that
p=12
Priya is preparing 8 ounces of fruit punch per person, so:
f= 8×p = 8×12 = 96
We need 96 ounces of fruit punch
Priya is preparing 2 ounces of cheese per person, so:
c= 2×p = 2×12 = 24
We need 24 ounces of cheese
A package of cheese contains 16 ounces and costs $3.99. In order to get all the cheese we need, Priya have to buy 2 packages of cheese.
2×16=32
32>24
A one-gallon jug of fruit punch contains 128 ounces and costs $2.50. Then, Priya have to buy only one gallon jug.
128>96
The budget would be:
b= $3.99×2 + $2.50×1
Answer:
12 square cm correct to 2 significant figures
Step-by-step explanation:
Area of a Rectangle = L X B = 2.1 X 5.6 = 11.76 square cm
To round your result to 2 significant figure, we start counting from the left from the first non-zero digit.
The first two digits are 11 but because the number after is 7 (greater than 4), we round up to 12.
11.76 square cm = 12 square cm correct to 2 significant figures
Answer:
Divisible by 3 is the answer
Step-by-step explanation:
First get everything to have the same base of 5
25^11 - 5^19
(5^2)^11 - 5^19
5^(2*11) - 5^19
5^22 - 5^19
Now factor out the GCF 5^19 to get
5^22 - 5^19
5^(19+3) - 5^(19+0)
5^19*5^3 - 5^19*5^0
5^19(5^3 - 5^0)
5^19(125 - 1)
5^19*(124)
At this point, we factor the 124 into 31*4 to end up with this full factorization: 5^19*31*4
Therefore, 25^11 - 5^19 is equivalent to 5^19*31*4
Since 31 is a factor of the original expression, this means the original expression is divisible by 31.
