It depends because u have to show us the diagram since we have to know if it is opposite or adjacent to the angle! Anyways I think u can solve it on your own! The question might have something to do with trigonometry like cos sin and tan! Remember the area of a triangle is 1/2*base*height

Answer:

C. 7/8

Step-by-step explanation:

3 1/2 = 3.5 and she picked 1/4 of that number. I divided 3.5 by 4 and got 0.875. I then turned that into fraction form for 7/8.

Write an equation in slope intercept form that passes through -2, 3 and Is parallel to the line with equation 3X +2y=6
soldier1979 [14.2K]

The equation of line is:  y=-\frac{3}{2}x as the y-intercept is zero

Step-by-step explanation:

Given

(-2,3)

Equation of line => 3x+2y=6

Converting the equation in slope intercept form

3x+2y=6\\2y=-3x+6\\Dividing\ both\ sides\ by\ 2\\\frac{2y}{2}=-\frac{3}{2}x+\frac{6}{2}\\y=-\frac{3}{2}x+3

The co-efiicient of x is the slope of the fiven line

So,

m=-3/2

The line parallel to given line will have the same slope as slopes of two parallel lines are equal

Now,

Slope-intercept form is:

y=mx+b

Putting the value of slope

y=-\frac{3}{2}x+b

to find the value of b, put (-2,3) in the equation

3=-\frac{3}{2}(-2)+b\\3=3+b\\b=0\\

Putting the value of b and m

y=-\frac{3}{2}x+0\\y=-\frac{3}{2}x

Hence,

The equation of line is:  y=-\frac{3}{2}x as the y-intercept is zero

Keywords: Slope-intercept form, Slope

Solve n^2+16n=17 by completing the square ​
larisa [96]

Answer:

305 or N=1

Step-by-step explanation:

N=17, correct?

so what you do first is rewrite the equation:

17^2+16

which will equal:

305

if not and the equation is N^2+16=17

then you have to subtract the 16 first from 17

n^2=1

now you divide or whatever you call it XD

/n^2=/1

so the answer to N=1

An engineering student answered 81 questons correctly ona 90 question test. What percent of the question did she answer correctl
SIZIF [17.4K]

Answer:

correct answer = 90%

Step-by-step explanation:

Let x be the percent of the question did she answer correctly.

Given:

An engineering student answered 81 questions correctly on a 90 question test.

Find the percent of the question did she answer correctly.

Solution:

Percentage formula is given below

% answer =\frac{correct\ answer}{total\ questions}\times 100

% answer =\frac{81}{90}\times 100

% answer =\frac{81\times 100}{90}

% answer =\frac{81\times 10}{9}

% answer =9\times 10

% answer =90

correct answer = 90%

Therefore, she answered 90% correctly.

Subtract.<br> (11x2 + 3x – 9)-(2x2 + 2x + 7)
xeze [42]

Answer:

3

Step-by-step explanation:

Simplify: (-7x2 - 3x) - (4x2 - x) ... -11x2 – 2x ... 3x – 5 + 23x – 9 = 3x + 23x – 5 – 9 = 26x – 14 = 2(13x – 7) Answer: 2(13x – 7). 11 . ... 2x - 3 + 3 = - 9 + 3, (Adding 3 on both sides) 2x = -6 2x/2 = -6/2
