What is the sum?
2/x2+4/x2

Answer: I think it’s B (25)

Step-by-step explanation:

Answer:

Using the sine rule,

36/sin(50)=20/sin(R)

46.9=20/sin(R)

Sin(R)=46.9/20=0.43

R=Sin¯¹(0.43)=25.2°=25°

R=25°

Answer:

  5/2

Step-by-step explanation:

Possible rational roots are ...

  ±(divisor of 9)/(divisor of 2)

So, the possibilities are ...

  ±1/2, ±1, ±3/2, ±3, ±9/2, ±9

The one on your list that is not among these is 5/2.

5/2 is not a possible rational root.

Answer:

83

Step-by-step explanation:

The nth term is   an=3n−7 .

30*3=90

90-7=83

so the 30th term would be 83

A list of four length-measurements doesn't actually have an area.

On my screen, the list is about 2cm wide and 4cm tall, so its area would be about 8cm².  But that's just on my laptop screen.  It would be different on a phone screen.

Answer:

A.

Step-by-step explanation:

The equation is ax^2 + bx + c = 0.

a = -1, and b = 1.

-1x^2 + 1x + c = 0

-x^2 + x + c = 0

Answer:

42 minutes

Step-by-step explanation:

Here we want to calculate the number of minutes ran in total.

Kindly note that;

Time = distance/speed

Her starting speed is 10 miles/hour

but she ran for 12 minutes.

Kindly note that 12 minutes = 12/60 = 1/5 = 0.2 hour

So total distance in the first 12 minutes is speed * time = 10 * 0.2 = 2 miles

Now the rest of distance to run would be ;

5 -2 = 3 miles

She ran 3 miles at a speed of 6 miles per hour.

Time spent here is 3/6 = 0.5 hours which is same as 30 minutes

Total time spent = 30 + 12 = 42 minutes

Answer:

CD = 2.8

Step-by-step explanation:

Quadrilateral ABCD is rotated to create Quadrilateral A'B'C'D' only. It is not dilated so all of its sides will be equal.

So,

CD = C'D'

Given that C'D' = 2.8

So,

CD = 2.8

Answer: 2.8

Step-by-step explanation: Khan Academy

Answer:

22m

Step-by-step explanation:

The computation is shown below:

Since it is a right-triangular garden so we use the pythagoreus theorem

As we know that

The C^2 refers to the longest side of the right-triangular garden

So,

a^2 + b^2 = c^2

a^2 + 14^2 = 26^2

a^2 + 196 = 676

a^2 = 480

So a = 22m

Hence, the other side of the garden is 22m

Answer:

x = 136

Step-by-step explanation:

A quadrilateral always has angles that sum to 360.  Thus, 47 + 95 + 82 + x = 360.  Subtract 47, 95, and 82 from each side and get x = 136.

Answer:

About 24 months

Step-by-step explanation:

1000-20= 980

980/40= 24.5

Answer: about 24 months

Step-by-step explanation:

First subtract 20 from 1000 and then divide the awnser by 40

1000-20= 980

1000/ 40= 24.5

Answer:

y  = −1/3x+17/3

Step-by-step explanation:

The line segment has slope -1/3. This means that any line perpendicular to it will have a slope of 3 (negative reciprocal)

Any line that bisects the line segment will pass through its midpoint. The midpoint is (5,4)

Midpoint formula: [tex]( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )[/tex]

So perpendicular bisector of this line  is simply a line with slope −1/3 that passes through point (5, 4)

y - 4 = -1/3 (x-5)=

y  =  −1/3x+17/3

Answer:

Hi!

The x-axis is the line that goes horizontal (from left to right) and the y-axis is the line that goes vertical (up and down). Intercepts are points that meet or intersect the axis. The x-intercept is (-40,0). The y-intercept is (0,15).

Answer:

1331:216

Step-by-step explanation:

Given the ratio of the lengths of two similar solids as a:b

The ratio of the surface areas = [tex]a^2:b^2[/tex]

The ratio of the volume = [tex]a^3:b^3[/tex]

We are given that the ratio of the surface areas of two similar geometrical solids is given by 121:36

Therefore:

[tex]a^2:b^2=121:36\\\implies a^2:b^2=11^2:6^2\\\implies a:b=11:6[/tex]

Since the ratio of the lengths is 11:6

The ratio of their volumes = [tex]11^3:6^3[/tex]

=1331:216

The ratio of the volume of the two similar geometrical solids is 1331:126.

Using Sine rule,

[tex] \frac{\sin 96 \degree}{48}=\frac{\sin Z}{10}\\

\implies \sin Z=\frac{5\sin (96\degree)}{24}\\

\implies Z \approx 12\degree[/tex]
