Answer:
c) 30%
Step-by-step explanation:
By dividing 20 up into 10, we get 2. Therefore, 10% of 20 is 2.
The price went from $20 to $14, a decrease of $6. Since 10% = $2, 30% would be $6.
So it was decreased by 30%
Answer:I think 30%

A pitcher contains 14.25 cups of iced tea. You drink 2.5 cups of the tea each morning and 2.25 cups of the tea each evening. When will you run out of iced tea?
Answers
Answer:
You will run out of iced tea in 3 days (a total of 3 mornings and 3 evenings)
Step-by-step explanation:
Day 1 - 9.5 cups left
14.25 - 2.5 - 2.25 = 9.5
Day 2 - 4.75 cups left
9.5 - 2.5 - 2.25 = 4.75
Day 3 - 0 cup left
4.75 - 2.5 - 2.25 = 0
Answer: You will run out of iced tea in 3 days
Step-by-step explanation:
2.5 + 2.25 = 4.75
14.25/4.75 = 3

Lorenzo has already jarred 6 liters of jam and will jar an additional 2 liters of jam every day. How many days does Lorenzo need to spend making jam if he wants to jar 12 liters of jam in all?
Answers
Answer:
Lorenzo will need 3 days to jar up 12 litres of jam (if you are from America, spell the word litre like this - liter)
Step-by-step explanation:
We start off with 6 litres of jam on the first day, plus another 2 litres, because the first day has passed.
6 + 2 = 8
This leaves us with 8 litres on day 1.
On day 2, we still have 8 litres, and have to add on 2 litres.
8 + 2 = 10
This leaves us with 10 litres on day 2.
On day 3, we still have 10 litres, and have to add on 2 litres.
10 + 2 = 12
STOP! The question asked for the amount of days Lorenzo needs to fill up 12 litres of jam. we have now reached 12 litres and we are at day 3. TA DAAAAAA! You have reached the end! Happy learning!

It is point c
Step-by-step explanation:
ok so the coordinates are always (x,y) so therefore if X is 0 then it stays in the middle of the graph and doesn't go anywhere. since Y is -3, y always goes down or up. so if it goes down then it is negative. up is always positive. same with x. X is always horizontal so if it moves right, it is positive and left (backwards) is negative. hope this helps and isn't confusing. *Also, since it's -3, then it goes down negative 3 units. *
Answer:
C
Step-by-step explanation:
In the coordinate (x,y), x refers to the place of point above the horizontal line while y represents the place of point in the side to its vertical lines.
Here, x is 0, that means it is lying on y line and y is -3, that means it's lying in 3rd quadrant. So, point C matches them completely. That's why the correct answer is C.

Answers
Answer: Choice A is correct
Explanation:
The LCM of the coefficients 14 and 16 is 112 because (14*16)/2 = 112. We multiply the values and divide by the GCF 2.
The 'a' terms are \(a^5\) and \(a^3\). We pick the one with the largest exponent when forming the LCM. Go for the smallest exponent when finding the GCF. Similar situations occur with the b and c terms as well.
So that's how we end up with \(112a^5b^4c^2\) as the LCM.
Side note: Choice D is the GCF of the two given expressions.

An experiment involves rolling two dice simultaneously. The following table shows the possible outcomes using the format of (die 1,die 2).
What is the probability of rolling 2 even numbers?
Answers
To determine the probability of rolling two even numbers, we need to find the favorable outcomes (outcomes with two even numbers) and divide it by the total number of possible outcomes.
The possible outcomes when rolling two dice are:
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)
(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)
(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)
(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)
(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)
(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)
Out of these, the favorable outcomes (outcomes with two even numbers) are:
(2,2), (2,4), (2,6), (4,2), (4,4), (4,6), (6,2), (6,4), (6,6)
Thus, there are 9 favorable outcomes.
The total number of possible outcomes is 36 (since each die has 6 possible outcomes).
Therefore, the probability of rolling 2 even numbers is:
\(\text{Probability} = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Possible Outcomes}} = \frac{9}{36} = \frac{1}{4} = 0.25\)
Hence, the probability of rolling 2 even numbers is 0.25 or 1/4.

Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV. He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV. Is Johnny making a valid inference about this population? (5 points)

Yes, it is a valid inference because his classmates make up a random sample of the students in the school
b
Yes, it is a valid inference because he asked all 26 students in his science class

No, it is not a valid inference because he asked all 26 students in his science class instead of taking a sample from his math class

Money is put into two accounts. Account A earns 3.5% interest annually, and account B ears 2.6% interest annually. Assuming $20,000 is split evenly among the accounts and interest is not compounded, how much interest would be earned in total after 6 years?
Answers
Answer:
The total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.
Step-by-step explanation:
After 6 years, the total interest earned on account A would be:
Interest = Principal x Rate x Time
Interest = $10,000 x 0.035 x 6
Interest = $2,100
The total interest earned on account B would be:
Interest = Principal x Rate x Time
Interest = $10,000 x 0.026 x 6
Interest = $1,560
Therefore, the total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.
Solve the equation to this problem
Answers
Answer:
x = - 6/7
Step-by-step explanation:
To start, 1x is just 1 times x, which you can just write as x.
x+3 = 8x+9
Then, you can bring x over to the other side of the equation, meaning it becomes -x. You can also think about subtracting x from both sides so it cancels out on the left.
3 = 8x+9-x
Next, do the same for the 9, so your equation looks like this:
3-9 = 8x-x
Just simplify it:
-6 = 7x
Finally, divide -6 by 7 to find x.
So, x = -6/7

First find area of triangle
Formula: (height * base)/2
Height = 5, base = 14
(5 * 14)/2 = 35 cm^2
Now find area of square
Square formula: l * w
Length = 2, width = 2
2 * 2 = 4 cm^2
Now subtract the square from the triangle
35 cm^2 - 4 cm^2 = 31 cm^2
Solution: shaded region is 31 cm^2
