Answer:
48% of 25 is 12.
Step-by-step explanation:
To find : what percent of 25 is 12?
Solution : Let x be the percentage of 25 which is 12
So, by the statement
x% of 25 = 12
Now, we have to calculate the value of x
Step 1- Write the expression
Step 2- divide 25 by 100
Step 3- Cross multiply
Therefore, 48% of 25 is 12.
<span>In the experiment, the weight that mice gain in different environment is analyzed. So, the weight of the mice is a variable that changes depending on the circumstances. Option A is eliminated.
The color of the mouse cages is irrelevant to the experiment, because it has no impact on the weight that mice gain. Option B is eliminated.
The length of time that the mice are observed must be constant for all experiments in order to obtain valid experimental results. All experiments should be done in the same period of time under different conditions.
The temperature of the laboratory room is independent variable. This means that the weight that mice gain can depend on this variable. So, changing the temperature maybe will lead to different weight gain of the mice.</span>
Answer:
x=6.67
Step-by-step explanation:
knowns:
both angles are equal to each other
so:
7x-15=4x+5
3x=20
x=20/3
x=6.666
Answer:
bag 3
Step-by-step explanation:
Let's call the labels "green", "red", and "mix".
Pick mix for two reasons :
- First, it's not mixed so whatever color you pick is the color of the pair.
- Also, if you pick from either of the other two, you can't know if it's a mixed bag or not.
So, let's pretend you pick a red out. Move the label red to the bag. This must be true - cannot be a mix.
Now, you have the mix label <u>in your hand</u>, <u>one bag with a label</u> (green), and <u>one bag without a label</u> (previously red).
Since all bags mislabeled to begin, move the green label to the <u>blank bag</u> - since this label must be wrong.
Put the mix label on the <u>remaining bag</u>.
Answer:
On the first situation the previous salary was $100,000 and on the second one the raise was 20%.
Step-by-step explanation:
On the first situation there was a decrease of 25% from the previous value, this mean that the present value is 100 - 25 = 75 % from what it was before. In order to calculate the previous value we can apply a rule of three as follows:
x -> 100%
75,000 -> 75%
x*75 = 75,000*100
x*75 = 7,500,000
x = 7,500,000/75 = 100,000
On the second situation there was an absolute increase of 78 - 65 = 13, this value represents the rate we want to know. In order to find the rate we can apply a rule of three as follows:
65 -> 100 %
13 -> x
1300 = 65*x
65*x = 1300
x = 1300/65 = 20 %
On the first situation the previous salary was $100,000 and on the second one the raise was 20%.
