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.

Question

Hugo is a veterinarian. he knows the following information about his 41 patrons:

â€¢ 20 patrons in total do not have a dog.

â€¢ 17 patrons in total have a cat.

â€¢ 7 patrons have neither a dog nor a cat

â€¢ 20 patrons in total do not have a dog.

â€¢ 17 patrons in total have a cat.

â€¢ 7 patrons have neither a dog nor a cat

Solution 1

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.

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 â€“ 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 Â 24 - 7 = 17, and the total of the people who have a **dog **is 17+4 = 21.

Question

selling price of car if rs 50,000 , profit is 10% and cost price of car will be ?

Solution 1

**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.

Joint

Solution 1

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 / vÂ²

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**.

J**oint 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 J**oint variation**, because there is not only **diect variation** or **inverse variation**.

Question

Find the x-intercept of the line 7x+7y= â€“ 1.

Solution 1

**Answer:**

(-1/7 ; 0)

**Step-by-step explanation:**

the line intercepts the x axis when y = 0

7x + 0 = -1

7x = - 1

7/7 x = -1/7

x = -1/7

Solution 2

**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

( -1/7 , 0)

A. 9

B. 9/4

C. 3/2

D. 9/16

Solution 1

**Answer:**

B

**Step-by-step explanation:**

xÂ² + 3x + 3 = 4 ( subtract 3 from both sides )

xÂ² + 3x = 1

to complete the square

add ( half the coefficient of the x- term )Â² to both sides

xÂ² + 2( [tex]\frac{3}{2}[/tex] )x + ([tex]\frac{3}{2}[/tex] )Â² = 1 + ( [tex]\frac{3}{2}[/tex] )Â²

(x + [tex]\frac{3}{2}[/tex] )Â² + [tex]\frac{9}{4}[/tex] = 1 + [tex]\frac{9}{4}[/tex]

that is [tex]\frac{9}{4}[/tex] is added to both sides
