2. Mary answered 6 questions correctly on her Biology test.
She answered 20% of the questions correctly. In total, how
many questions were on the Biology test?
Answer:
60
Step-by-step explanation:
if 6 questions is 20 percent, that means every 3 questions should be 10 percent. 60÷3=20
Answer:
The Answer is 30 questions in total.
Step-by-step explanation:
1. The first thing you would want to do is to break down this question.
For every 6 questions, this is 20% of the test done.
2. You now would want to divide 100% (the full amount on the test) by 20%.
100%/20% = 5
3. Now, multiply both to get your answer.
6·5= 30
20%x5= 100%.
Therefore, the total amount of questions on the test is 30 questions.

the scale drawing of a rectangular room measures 10 cm long by 6 cm wide. the actual width of the room is 15 feet. what is the actual perimeter of the room, in feet?
Answer:
80 feet
Step-by-step explanation:
6 cm = 15 feet
1 cm = 5/2 feet
32 cm = 90 feet
The actual perimeter of the room is 90 feet.
What is a scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object,
We have,
The scale drawing of a rectangular room measures 10 cm long by 6 cm wide.
The actual width of the room is 15 feet.
This means,
6cm = 15 feet
1 cm = 15/6 feet
1 cm = 5/2 feet
Now,
The perimeter of the rectangular room.
= 2(10 + 6)
= 2 x 16
= 32 cm
1 cm = 5/2 feet
So,
32 cm = 32 x 5/2 feet
32 cm = 16 x 5 feet
32 cm = 90 feet
Thus,
The actual perimeter of the room is 90 feet.

How to find the rational zeros of a function
Answer:
Step-by-step explanation:
Find the zeroes of the function f ( x ) = x 2 + 12 x + 32
First, because it's a polynomial, factor it f ( x ) = ( x + 8 ) ( x + 4 )
Then, set it equal to zero 0 = ( x + 8 ) ( x + 4 )
Set each factor equal to zero and the answer is x = − 8 and x = − 4 .

Enter your answer in the box.
Answer:
x = 50
Step-by-step explanation:
→ Make the equations equal to each other
2 ( x + 10 ) = 3x - 30
→ Expand brackets
2x + 20 = 3x - 30
→ Minus 3x from both sides
-x + 20 = -30
→ Minus 20 from both sides
-x = -50
Opposite angles are equal

Slope is 1 and (-2, -1) is on the line.
Answer:
You can’t find the slope of a line if only given one point. If you had a visual representation of the line such as a graph or a table you could find a second point and then use the formula for slope, y = (y2-y1) / (x2-x1).
Imagine a single point on the xy graph. You could take a random point elsewhere from an infinite number of points and would be able to draw a line and find the slope. This means there could be an infinite number of different slopes for one point. One point on an unknown line is not enough information to determine the slope of its line without a graph or a table.

Which of the following describes a gerund and how it functions in a sentence? (1 point)
O A gerund is a noun that functions as the subject of a sentence.
O A gerund is a noun that functions as the direct object receiving the action in a sentence.
O A gerund is a verb ending in -ing that functions as a verb in a sentence.
O A gerund is a verb ending in -ing that functions as a noun in a sentence.
Answer:
a
Step-by-step explanation:
The accurate definition of the gerund and its purposes is "gerund is a verb ending in -ing that serves as a noun in a phrase." Thus, option fourth is correct.
What is sentence?Sentence refers to a set of words that are appropriately ordered in a line and provide the sense or meaning. When the line imparts meaning to the words, it is considered to be a sentence.
A combination of words that may transmit a statement, question, exclamation, or demand on their own. Sentences generally include a subject and a predicate, as well as one main clause and one or more subsidiary clauses.
Gerund is a verb form that includes -ing at the end of the word and functions as a noun in the phrase. Gerunds, like the other two forms of verbals, are founded on a verb and hence reflect the verbal category.
Therefore, it can be concluded that option fourth is correct.

A line that includes the points ( – 8,9) and ( – 10,d) has a slope of 6. What is the value of d?
Answer:
The value of d is -3.
Step-by-step explanation:
We are given that a line that includes the two points (-8, 9) and (-10, d) have a slope of 6. We want to determine the value of d.
Recall that the formula for slope is:
[tex]\displaystyle m = \frac{\Delta y}{\Delta x}[/tex]
We know that the slope is 6. Substitute:
[tex]\displaystyle (6) = \frac{(d) - (9) }{(-10) - (-8)}[/tex]
Solve for d:
[tex]\displaystyle \begin{aligned} 6 & = \frac{d - 9}{-10 + 8} \\ \\ 6 & = \frac{d - 9}{-2} \\ \\ -12 & = d - 9 \\ \\ d & = -3 \end{aligned}[/tex]
In conclusion, the value of d is -3.
