Course Grade You were 6 points shy of a B in yo
394. How many points were possible in the course?
mathematics course. Your point total for the course was
(Assume that you needed 80% of the course total for a B.)
Solution 1
The point total possible for the given course is equal to 500.
What is a Percent?
- A ratio whose second term is 100 is known as a percent.
- Parts per hundred are used in percentages.
- The mathematical representation of percent is %.
- The percent formula is given as, [tex]x=p \times b[/tex], where b is the base number, x is the number being compared to b, and p is the percent in decimal form.
In the question, it is given that you were 6 points shy of a B and the current total points you have is 394.
So, the total number of points you require for a B is calculated as,
[tex]394+6=400[/tex]
So, the value of x is 400.
It is given that you need 80% of the course total for a B.
[tex]\implies p=\frac{80}{100}\\ \implies p=0.8[/tex]
Here, we have to find the base number (b).
We have, x = 80% of b
[tex]\implies x=0.8 \times b\\\implies 400= 0.8 \times b\\\implies x=\frac{400}{0.8}[/tex]
Simplifying, we get
[tex]x=500[/tex]
Therefore, 500 points were possible in the course.

• 20 patrons in total do not have a dog.
• 17 patrons in total have a cat.
• 7 patrons have neither a dog nor a cat
The number of persons who own a dog but no cat is 24 - 7 = 17, while the total number of people who own a dog is 17 + 4 = 21.
What exactly does "patron" mean?
formal a customer of a specific eatery, lodging facility, or other establishment. Only customers may use this parking lot. synonyms and words that are similar. a hotel or guest house stay.
Since there are a total of 41 customers, the number of those without cats is calculated as follows: 41 – 17 = 24.
13 people(20 - 7) do not own dogs but do own cats.
There are 4 persons who own both a dog and a cat (17 - 13).
The people who have a dog, and do not have a cat is  24 - 7 = 17, and the total of the people who have a dog is 17+4 = 21.

Answer:
Rs 45,000
Step-by-step explanation:
The profit is the difference between the selling price and the cost price of the car. In this case, the profit is 10% of the selling price, or 10% * Rs 50,000 = Rs 5,000.
Therefore, the cost price of the car is the selling price minus the profit, or Rs 50,000 - Rs 5,000 = Rs 45,000. This is the amount that the seller paid for the car, before adding the profit.

The correct option is Joint variation, because there is not only diect variation or inverse variation.
What is variation in mathematics?
It gives the relationship between a set of variables with the other set of variables.
Consider the given equation.
R = kst / v²
In this question, details of variables is not given hence, consider k is constant and s, t, and v are variables.
Direct variation: When one variable is directly proportional to the other variable then the relation is known as direct variation.
Joint variation: When a variable depends directly or inversely on 2 or more than two variables then the variabtion is known as Joint variation.
Inverse: When a variable varies inversaly with respect to other variable then the the variation is known as inverse variation.
In the equation, there are 3 variables, R varies directly as s and t and varies inversely as [tex]v^2[/tex].
Hence, the correct option is Joint variation, because there is not only diect variation or inverse variation.

7x + 0 = -1
7x = - 1
7/7 x = -1/7
x = -1/7
Answer:
The x intercept is -1/7
( -1/7 , 0)
Step-by-step explanation:
To find the x intercept, set y =0 and solve for x
7x+7y = -1
y =0
7x+7(0) = -1
7x +0 = -1
7x = -1
Divide by 7
7x/7 = -1/7
x = -1/7
The x intercept is -1/7

A. 9
B. 9/4
C. 3/2
D. 9/16
Answer:
B
Step-by-step explanation:
x² + 3x + 3 = 4 ( subtract 3 from both sides )
x² + 3x = 1
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2( [tex]\frac{3}{2}[/tex] )x + ([tex]\frac{3}{2}[/tex] )² = 1 + ( [tex]\frac{3}{2}[/tex] )²
(x + [tex]\frac{3}{2}[/tex] )² + [tex]\frac{9}{4}[/tex] = 1 + [tex]\frac{9}{4}[/tex]
that is [tex]\frac{9}{4}[/tex] is added to both sides
