How meny cup of smoothies can you get with 3 quarts of orange juice,5 pints of milk and 5 cups of pineapple juice.
Answers
Answer:
27 cups
Step-by-step explanation:
Amount of orange juice in the mixture = 3 quarts
Therefore, number of cups of orange juice = 3 × 4 cups [Since, 1 quarts = 4 cups]
= 12 cups
Amount of milk in the mixture = 5 pints
Therefore, amount of milk in cups = 5 × 2 [Since, 1 pint = 2 cups]
= 10 cups
Amount of pineapple juice in the mixture = 5 cups
Amount of mixture = Amount of Orange juice + Amount of pineapple juice + Amount of milk
= 12 + 10 + 5
= 27 cups
Therefore, total amount of smoothies = 27 cups

Which of the following shows the extraneous solution to the logarithmic equation log7(3x^3+x)-log7(x)=2?
Answers
Answer:
x=4
Step-by-step explanation:
on edge
The extraneous solution to the logarithmic equation log₇(3x²+x)-log₇x=2 is x=16
What is logarithm?When you raise a number with an exponent, there comes a result.
Lets say you get[tex]a^b = c[/tex]
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = \log_a(c)[/tex]
'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'
We are given the function as;
log₇(3x²+x)-log₇x=2
Domian: 3x²+x>0
x(3x+1)>0
x∈(-∞,-1/3)U(0,∞)
Hence, x∈(0,∞), Thus x∈(0,∞)
In this problem we use the following formula:
[tex]\boxed {log_ax-log_ay=log_a\frac{x}{y}}\displaystyle\\log_7(3x^2+x)-log_7x=2\\\\log_7(x(3x+1))-log_7x=2(1)\\\\log\frac{x(3x+1)}{x} =2(log_77)\\\\log(3x+1)=log_77^2\\\\log_7(3x+1)=log_749\\\\\\\\3x+1=49\\\\3x+1-1=49-1\\\\3x=48\\\\x=16[/tex]

Which of the expressions below has a 1 in the tenths place of the product? Select all that apply. A) 18.3 x 7 B) 6.5 x 4.31 C) 8.54 x 2.3 D) 5.4 x 2.8
Answers
Answer: A) 18.3 x 7 and D) 5.4 x 2.8
Step-by-step explanation:
A) 18.3 x 7 = 128.10
We can infer that 1 is in the tenths place.
B) 6.5 x 4.31 = 28.015
We can infer that 1 is not in the tenths place but rather the hundredths place.
C) 8.54 x 2.3 = 19.642
We can infer that 1 is not in the tenths place.
D) 5.4 x 2.8 = 15.12
We can infer that 1 is in the tenths place.
Susan has 50% more books than Michael. Michael has 40 books. If Michael buys 8 more books, will Susan have more or less books than Michael? Use any method to solve the problem
Answers
Answer:
Susan has more books than Michael.
Step-by-step explanation:
If Susan has 50% more books and Michael has 40 books, that means Susan has 1.5 times 40 = 60
40 + 8 = 48
60 is more than 48, so Susan has more books than Michael

To prepare for a party, Jada poured 0.45 liter of juice into each of several cups. Altogether she poured 9 liters of juice into the cups.
Answers
Answer: 20 cups
Step-by-step explanation:
Question would like to know the number of cups that Jada poured juice into.
If each cup got 0.45 litres, the number of cups that Jada poured drinks into would be the total amount of juice poured divided by the quantity per cup:
= Total juice poured / Quantity per cup
= 9 litres/ 0.45 litres per cup
= 20 cups
