Answer:

The number is 17

Step-by-step explanation:

Let the number be n.  Increasing this by 30 results in n + 30.  Tripling this result results in 3(n + 30) = 141.

Multiplying as indicated:  3n + 90 = 141, or

                                            3n = 51

Solving for n, we get n = 51/3 = 17

The original number is 17.

Step-by-step explanation:

3(x+30)=141\\\\\frac{3(x+30)}{3}=\frac{141}{3}\\\\x+30=47\\\\x+30-30=47-30\\\\x=17

mr_godi [17]

Correct option is C. As used in line 50, "reason" most nearly means intellect.

<h3>Line from the passage - </h3>

Line 50: ...unless freedom strengthens her reason till she comprehends her duty, and sees in what manner it is connected with her real good?

<h3>This question is based on paragraph from Mary Wollstonecraft, A Vindication of the Rights of Woman. Originally published in 1792, which is given below -</h3>

" That half the human race is excluded by the other half from any participation in government; that they are native by birth but foreign by law in the very land Line where they were born; and that they are

5 property-owners yet have no direct influence or representation: are all political phenomena apparently impossible to explain on abstract

"Contending for the rights of woman, my main argument is built on this simple principle, that if she be not prepared by education to become the companion of man, she will stop the progress of 45 knowledge and virtue; for truth must be common to all, or it will be inefficacious with respect to its influence on general practice.

What is the area of triangle pqr on the grid? a triangle pqr is shown on a grid. the vertex p is on ordered pair 7 and 6, vertex
horsena [70]

P(7,6), Q(1,6), R(4,2)

We have PQ parallel to the x axis. We'll call that the base,

b = 7 - 1 = 6

The altitude is then the y difference h = 6 - 2 = 4

The area is \frac 1 2 bh = \frac 1 2 (6)(4) = 12

Answer: 12 square units


In general we can use the shoelace formula for the area of any polygon given coordinates. We write the points like this:

(7,6), (1,6), (4,2)

(1,6), (4,2), (7,6)

The area is then half the absolute value of the sum of the cross products:

A = \frac 1 2 | 7(6)-6(1) + 1(2)-6(4) + 4(6)-2(7) | = \frac 1 2 |24| = 12
