The diagonals of kite ABCD intersect at E. If ∡EBC=30°, what is ∡BCE?

Answers

Answer 1

Answer:

∡BCE = 60

Step-by-step explanation:

Here, we want to find the angle marked BCE

From our diagram, the angle marked BCE is y

Looking at triangle BCE, we have the right angle, an angle measure of 30 and the angle marked y which we say is BCE

mathematically, the sum of all these will give 180 as the sum f the interior angles of a triangle is 180

Thus, we have that;

y + 30 + 90 = 180

y = 180-120

y = 60

11. Slope of the line is 7/10.

12. Slope of the line is [tex]-\frac{1}{3}[/tex]

Step-by-step explanation:

11. Given points are:

(-6, 1) and (4, 8)

Slope of a line is given by the formula;

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{8-1}{4-(-6)}[/tex]

m = [tex]\frac{7}{4+6}[/tex]

m = [tex]\frac{7}{10}[/tex]

Slope of the line is 7/10.

12. Given points are:

(2, -3) and (5, -4)

Slope of the equation is;

m = [tex]\frac{-4-(-3)}{5-2}[/tex]

m = [tex]\frac{-4+3}{3}[/tex]

m = [tex]\frac{-1}{3}[/tex]

Hence,

Slope of the line is [tex]-\frac{1}{3}[/tex].

Step-by-step explanation:

Volume= L*H*W

So the volume is 1

I hope this helps!!!

The volume of cube is 1 feet³.

What is Volume of Cube?

Volume = a³, where a is the length of the cube's sides or edges, is the formula for the cube's volume.

The basic formula for volume is length x  breadth x height, as opposed to length, width, and height for the area of a rectangular shape.

Given:

Edge length of cube= 1 feet.

So, Volume of cube = l³

                                  = (1)³

                                  = 1 x 1 x 1

                                  = 1 ft³

Hence, the volume is 1 feet³.

Three apples and six pears cost $7.44. Four apples and ten pears cost
$11.58. Find the cost of an apple.

Answers

Answer:

$0.86

Step-by-step explanation:

Let's say the cost of the apples is A and the cost of the pears is P.

3A+6P=7.44

4A+10P=11.58

Now our best bet is elimination. We have to multiply the equations (Dont' forget about both sides, otherwise it does not work!) by the least common multiple.

We want to keep the variable A, meaning we'll have to target B. The least common multiple is 30, so now we'll multiply both equations like so:

15A+30P=37.20

12A+30P=34.74

Now we subtract the second equation from the first one. We get:

3A=2.46

And we divide both sides by 3, leaving us with

A=$0.86 or 86 cents.

Find the equation of a line parallel to the line 2x-y-9=0 and passing through the point of intersection of the lines 5x+y+4=0 and 2x+3y=1

Answers

Answer:

[tex]y=2x-3[/tex]

Step-by-step explanation:

1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to [tex]2x-y-9=0[/tex]

[tex]5x+y+4=0[/tex]

[tex]y= -4-5x[/tex]

substituting the value of y in [tex]2x+3y=1[/tex]:

[tex]2x +3(-4-5x)=1\\\\2x-12-15x-1=0\\-13x=13x\\x= \frac{13}{-13}= -1[/tex]

substituting x=-1 in y= -4-5x:

[tex]y= 1[/tex] (upon solving, you should get this)

[tex](x,y)= (-1,1)[/tex]

2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)

[tex]2x-y-9=0\\2x-9=y\\y= 2x-9[/tex]

[tex]y= mx+c\\[/tex]

-1= 2 x 1 +c

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given that, Mark makes a total of $500 for every 3 clients she acquired.

∴ To find how many clients he needs to earn $10,000 in a day we have to divide the earnings wanted by earnings per client which is,

= (10000)÷(500/3).

= 10000×3/500.

Answer:

y = -1/7x y = 2x -7

Step-by-step explanation:

1. The slope of the given line is the x-coefficient, 7. The slope of the perpendicular line is the negative reciprocal of this: -1/7. Since the line goes through the origin, the y-intercept is zero.

  y = -1/7x

__

2. The first part of this problem is to find the solution to the given system of equations. We can substitute for x to do that:

  3(5 -y)-2y = 10

  15 -5y = 10 . . . simplify

  -3 +y = -2 . . . . divide by -2

  y = 1, x = 4 . . . add 3 to find y; subtract y from 5 to find x

__

The second part of this problem requires we note the slope of the parallel line. It is the x-coefficient, 2. The y-intercept can be found from ...

  b = y -mx = 1 -2(4) = -7

So, the desired line in y=mx+b form is ...

  y = 2x -7
