Hello,
A)
h max
A:-2x/100+32/100=0==>x=16
B:-2x/100+18/100=0==>x=9
B)
y=0
A:-x²+32x+400=0==>x=41.612496... or x=-9.61... exclude
B:-x²+18x+500=0 ==> x=28.1039415...or x=-15.1039.. exclude
C)
x=0
A:y=4
B:y=5
D)-x²/100+32/100x+4=-x²/100+18/100x+5
==>14/100*x=1 ==>x=50/7=7.1428....
She would need 17 pizzas to feed everyone if there is 50 and 14 if there is there is 40. it would cost her 195.50 dollars for 50 people and 161 for 30
Answer:
=6590000000 or 6.59 x 10^9 (^ raises the number as an exponent)
Step-by-step explanation:
=(6.648 x 10 to the power of 9) - (2.9 x 10 to the power of 7)
or we could just expand the numbers
like,
= 6619000000- 29000000
and then calculate to get the answer which equals 6590000000 or 6.59 x 10^9 when written in a scientific form
Since she has 57 cans and 3 cans are allready devoted to the last row u must do 57-3 in or to get 54 cans total leftover. Then divide the number 54 by 9 since there are nine rows.so i think there will be six cans on each row of the shelf!
Answer:
I will: Multiply 32 times 20 to get the total cost of the foods and tickets. Then I will add the total cost of the tickets and the total cost of the bus to get the total cost of the trip. Lastly I will divide the total cost of the trip by 2 to find out how much money the class need to earn.
Solution: 32 • 20 = 640 + 900 = 1,540 ÷ 2 = 770
Answer: 770
