Answer:

x = 12

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

9x + 11 + 3x - 15 + 2x + 16 = 180, simplify left side

14x + 12 = 180 ( subtract 12 from both sides )

14x = 168 ( divide both sides by 14 )

x = 12

Answer:

-65

Step-by-step explanation:

We can use the slope formula

m= (y2-y1)/(x2-x1)

   = (-5-60)/(73-72)

   = -65/1

  = -65

Answer:

The slope of the line that passes through (72, 60) and (73, -5) is -65.

Step-by-step explanation:

The formula for finding the slope of a line is (y₂₋y₁) / (x₂-x₁).

Substitute the points into the formula and solve.

(-5 - 60) / (73 - 72) =

(-65) / (1) = -65

The slope of the line is -65.

Answer:

330488  doctors

Step-by-step explanation:

Take the percentage times the total number of doctors

16.4% * x =54200

Change to decimal form

.164x = 54200

Divide each side by .164

x = 54200/.164

x =330487.8049

x =330488

Answer:

8888.8

54,200 is your whole total. Out of 54,200 16.4 percent were female. To the find the answer, we would multiply 16.4 by 54200 and divide it by 100.

Answer:

D)Both parabolas open to the right, and [tex]x=2y^2[/tex] is wider than [tex]x=8y^2.[/tex]

Step-by-step explanation:

Standard equation of parabola :

[tex]y=a(x-h)^2+k.[/tex]

If a < 0, then the parabola open downwards and if a > 0, then the parabola open upwards.

[tex]x=a(y-k)^2+h[/tex]

If a < 0, then the parabola open left and if a > 0, then the parabola opens right

Given equations : [tex]X=2y^2[/tex] and [tex]X=8y^2[/tex]

[tex]x=2(y-0)^2[/tex] and [tex]x=8(y-0)^2[/tex]

in both the equations a>0

So, Both parabolas are open to the right.

Refer the attached graph

[tex]x=2y^2[/tex] ---- Red

[tex]x=8y^2[/tex] --- blue

So, [tex]x=2y^2[/tex] is wider than [tex]x=8y^2.[/tex]

So, Option D is true

Answer:$140 for the train ride

$84 for the museum

Step-by-step explanation:

28×5

28×3

All the students + you = 28

If not, try 27×5 and 27×3

Answer:

Step-by-step explanation:

There are two values to find and add together.

o The admission cost for the Museum

o The admission cost for the Train Ride

Let's make some equations.

x=number of people

Museum: 3x=total cost for Museum (m)

Train Ride: 5x=total cost for Train Ride (t)

m+t= total money spent

Now, let's replace the values.

Museum: 3(27)=$81

Train Ride: 5(27)=$135

$81+$135=$216 for the Train Ride and visit to the Museum.

Hope this helps!

Step-by-step explanation:

Answer:

Oh! that expression is equal to 4

Step-by-step explanation:

[tex]\sqrt{2\sqrt{7} -\sqrt{12} } \cdot \sqrt{2\sqrt{7} +\sqrt{12} }[/tex]

First, rewrite [tex]\sqrt{12} =\sqrt{2 \cdot 2 \cdot 3}=2\sqrt{3}[/tex]

[tex]\sqrt{2\sqrt{7} -2\sqrt{3} } \cdot \sqrt{2\sqrt{7} +2\sqrt{3} }[/tex]

[tex]\sqrt{2\sqrt{7} -2\sqrt{3} } \cdot \sqrt{2\sqrt{7} +2\sqrt{3} }[/tex]

Now we got a difference of two squares, therefore,

[tex](2\sqrt{7} -2\sqrt{3})(2\sqrt{7} +2\sqrt{3})=(2\sqrt{7} )^2-(2\sqrt{3})^2=[/tex]

[tex]= (4 \cdot 7)-(4 \cdot3)=28-12=16[/tex]

[tex]\sqrt{2\sqrt{7} -2\sqrt{3} } \cdot \sqrt{2\sqrt{7} +2\sqrt{3} }=\sqrt{16}[/tex]

[tex]\sqrt{16} = 4[/tex]

Answer: 34.27 sq. mm.

Step-by-step explanation:

Area of a triangle = hb / 2

= 8 x 4 / 2

= 32 / 2 = 16 mm

Area of the circle = πr^2

= π x 4^2

= 50 27 sq. mm.

Area of the shaded part

= 50.27 - 16

= 34.27 sq. mm

Answer: the answer is c, 34.24 mm

Step-by-step explanation: I just did the test

Answer:

150 m

Step-by-step explanation:

Since we have a dome inscribed in a rectangle, and are given the width of the rectangle, we can,

1. Find the diameter of the circle, which is also 150m

2. Find the length of the rectangle, which is 75m (the length of the rectangle is the same as the radius of the circle)

If we are to find the perimeter of the shaded region, we add the length and half the width of the rectangle. So,

75 + 75 = 150m

Answer:

Angle ABC =70

Step-by-step explanation:

Divide 140 by 2 and apply the rule of alternante interior angles

In the given rhombus the unknown measure of ∠ABC is 70 degrees.

A rhombus is a quadrilateral that has its opposite sides to be parallel to be each other.

This means that the two interior opposite angles are equal to each other.

The opposite angle of ∠B is 140 degrees.

So the angle at  ∠B is also 140 degrees because the opposite angles of rhombus are equal.

As we finding the half of angle ∠B.

Divide 140 degrees by 2.

∠ABC=140/2

=70 degrees.

Hence, the angle measure given in the figure is 70 degrees.

Answer:

Step-by-step explanation:

The expression: ~q means "not q"

If ~q is false, then q is true

The expression:

If p is true and ~q is false

is equivalent to:

If p is true and q is true

then:

If p is true and q is true, then p -> q is never false (or is always true, see table attached). Or:

If p is true and ~q is false, then p -> ~q is never false.

Answer:

The turning point of the graph is at (3,-16)

Step-by-step explanation:

The general equation of curve is given as:

y = x² + ax + b

The two point for which the equation satisfies is (0,-7) and (7,0).

Substitute (0,-7) in the general equation:

y = x² + ax + b

-7 = 0² + a(0) + b

b = -7

Substitute (7,0) in the general equation:

y = x² + ax + b

0 = 7² + 7a + b

Where b = -7

0 = 49 + 7a - 7

0 = 42 + 7a

a = -6

The equation of the curve is:

a = -6 and b = -7

y = x² + ax + b

y = x² - 6x - 7

Graph of the equation is attached below.

We can see that the the turning point of the graph is at (3,-16)

Answer:

y = -1/2x+2

Step-by-step explanation:

Two points on the line are (0,2) and (4,0)

We can find the slope

m = (y2-y1)/(x2-x1)

   = (0-2)/(4 -0)

   = -2/4

    - 1/2

We know the y intercept is 2 since it crosses the y axis at 2

The slope intercept form is

y = mx+b where m is the slope and b is  the y intercept

y = -1/2x+2

Answer:

See below.

Step-by-step explanation:

First, from the graph, we can already pick out two points: (0,2) and (4,0). Note that (0,2) is the y-intercept.

Therefore, we can use slope-intercept form or [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.

We already know the b, so:

[tex]y=mx+2[/tex]

Now, we can plug in the ordered pair (4,0) to help us determine the slope (or you can just use the slope formula for the two ordered pairs):

[tex]0=m(4)+2[/tex]

[tex]-2=4m[/tex]

[tex]m=-1/2[/tex]

Thus, the entire equation is:

[tex]y=-\frac{1}{2} x+2[/tex]

Answer:

There is some mistake in the question, because the solutions are x = -1.445 and x = -34.555

Step-by-step explanation:

Given the functions:

f(x) = x² + 4x + 10

g(x) = -32x - 40

we want to find the points at which f(x) = g(x).

x² + 4x + 10 = -32x - 40

x² + 4x + 10 + 32x + 40 = 0

x² + 36x + 50 = 0

Using quadratic formula:

[tex]x = \frac{-b \pm \sqrt{b^2-4(a)(c)}}{2(a)} [/tex]

[tex]x = \frac{-36 \pm \sqrt{36^2-4(1)(50)}}{2(1)} [/tex]

[tex]x = \frac{-36 \pm 33.11}{2} [/tex]

[tex]x_1 = \frac{-36 + 33.11}{2} [/tex]

[tex]x_1 = -1.445 [/tex]

[tex]x_2 = \frac{-36 - 33.11}{2} [/tex]

[tex]x_2 = -34.555[/tex]

Answer:

CD

Step-by-step explanation:

CD is perpendicular to XY and also cuts XY into two equal halves.

FH is not perpendicular to XY even though it cuts XY into two equal halves.

DH is not a line.

FG is perpendicular to XY but it does not cut XY into equal halves.

CD segment is the perpendicular bisector of XY¯.

The perpendicular bisector of a line segment is a line that passes through the midpoint of the segment and is perpendicular to the segment. It intersects the segment at its midpoint and divides the segment into two segments with equal lengths.

Of the given options, only CD intersects XY at its midpoint and divides the segment into two segments with equal lengths. Therefore, CD is the perpendicular bisector of XY.

The other options do not intersect XY at its midpoint or do not divide the segment into two segments with equal lengths. For example, FH intersects XY at point H, but point H is not the midpoint of XY. Additionally, the segments HF and FH do not have equal lengths.

Therefore, the answer is CD.
