Answer:
The equation to find , the number of servings eaten during the month is:
B.
Step-by-step explanation:
Given:
Number of servings of trail mix made by Shiloh = 89
Number of servings of trail mix left by the end of month = 55
To write an equation to find which is the number of servings eaten during the moth.
Solution:
The total number of servings of trail mix made = 89
Number of servings eaten during the month =
<em>Servings of trail mix left by the end of the moth can be given as:</em>
⇒
Number of servings actually left by the end of the month = 55
Thus, the equation to find , the number of servings eaten during the month is:
(Answer)
On solving for we get the number of servings eaten.
Answer:
The side length of the prints is approximately 34.785 inches.
Step-by-step explanation:
First, we have to calculate the area of the original oil painting (), measured in square inches, by the following formula:
(1)
Where is the length of the side, measured in inches.
And the length of the miniature is determine by means of reduction factor (), with no unit:
(2)
If we know that and , then the side length of the miniatures is:
The side length of the prints is approximately 34.785 inches.
A) The rational equation that represents the given situation in the question is;<u><em> (21 + x) = 0.9(25 + x)</em></u>
B) Solving the equation gives the number of points needed to bring his average to 90% as; <u><em>15 points</em></u>
We are told that he earned a total of 21 out of 25 possible points.
A) Now, if he has a perfect score on the next several quizzes, it means the number of points which we will call x that he needs to bring his average up to 90% is calculated from the rational equation;
(21 + x)/(25 + x) = 90%
⇒ (21 + x)/(25 + x) = 0.9
⇒ (21 + x) = 0.9(25 + x)
B) To find the number of points, let us solve the equation in A above to get;
(21 + x) = 0.9(25 + x)
Using distributive property on the right hand side, we have;
21 + x = 0.9(25) + 0.9x
21 + x = 22.5 + 0.9x
Using subtraction property of equality;
x - 0.9x = 22.5 - 21
0.1x = 1.5
x = 1.5/0.1
x = 15 points
