Answer:
the ratio of the surface area of A to the surface area of B is 36 ÷ 49
Step-by-step explanation:
The computation of the ratio of the surface area of A to the surface area of B is shown below;
= Surface area of the sphere a ÷ surface area of the sphere b
= 4πr^2 ÷ 4πr^2
= 6^2 ÷ 14 ÷ 2^2
= 36 ÷ 49
hence, the ratio of the surface area of A to the surface area of B is 36 ÷ 49

Explanation:
We will prove by contradiction. We assume that the given sum is rational, and the ratio can be expressed in reduced form by p/q, where p and q have no common factors.
[tex]\sqrt{n-1}+\sqrt{n+1}=\dfrac{p}{q}\qquad\text{given}\\\\(n-1)+2\sqrt{(n-1)(n+1)}+(n+1)=\dfrac{p^2}{q^2}\quad\text{square both sides}\\\\2(n+\sqrt{n^2-1})=\dfrac{p^2}{q^2}\qquad\text{simplify}[/tex]
We note that this last equation can have no integer solutions (n, p, q) for a couple of reasons:
for any integer n > 1, the root √(n²-1) is irrational (n² is a perfect square; n²-1 cannot be.)p²/q² cannot have a factor of 2, as √2 is irrationalThere can be no integer n for which the given expression is rational.

Write an equation of the line that passes through the points (-3, -9) and (5, -9).
y = -9
Ok so to write the equation of the line you will need the slope and y-intercept. Since we are given two-point we can easily find the slope by using this equation for slope formula:
[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
So now that we have our equation we can just plug in the numbers:
[tex]\frac{(-9)-(-9)}{5-(-3)}[/tex]
After subtracting you should get:
0/8
Since zero is in the numerator and you can't divide zero by anything, the slope is 0. We still need the y-intercept for the equation however since the slope is 0 there is no need to put anything else.
Then to find the y-intercept all you have to do is plug in one of the coordinatines into the slope equation to solve, for example, using the point (5,-9):
[tex](-9) = 5(0) + b[/tex]
B is the variable for the y-intercept. Also notice how I put 0 as our slope into the equation. Now all you have to do is solve for b. Which you would get b = -9. Since you have your slope and your y-intercept now you just write out your equatoin for the line which is:
y = 0x - 9
**Just write it as
y = -9
Answer:
Y = -9

lines m and p are cut by the transversal n. determine the value of x. write the measures of the six angles. show all work
Answer:
x = 36°
m<1 = 36°
m<2 = 144°
m<3 = 36°
m<4 = 144°
m<5 = 144°
m<6 = 36°
Step-by-step explanation:
✔️x° + 4x° = 180° (linear angle pair theorem)
5x = 180
x = 180/5
x = 36°
For easy identification, the six angles to be found have been labelled <1 to <6 as shown in the attachment below.
✔️m<1 = x° (vertical angles pair)
m<1 = 36° (substitution)
✔️m<2 = 4x° (vertical angles pair)
Plug in the value of x
m<2 = 4(36)
m<2 = 144°
✔️m<3 = x° (alternate interior angles theorem)
m<3 = 36° (substitution)
✔️m<4 = 4x° (corresponding angles theorem)
m<4 = 4(36) (substitution)
m<4 = 144°
✔️m<5 = 4x° (alternate exterior angles theorem)
m<5 = 4(36)
m<5 = 144°
✔️m<6 = x° (corresponding angles theorem)
m<6 = 36°

if 5 bags of sugar with equal weight weigh 35 kg, how many bags of sugar would weigh 56 kg?
Answer:
8 bags
Step-by-step explanation:
If 5 bags equal 35 kg, then each bag will weigh 35/5 or 7 kg. If there are 56 kg and you want to find the number of bags, you divide 56 by 7 and you get 8.

A box contains 5 red pens 10 white pens and 20 green pens if one pen is taken out of
the box at random. What is the probability that the pen taken out will be
i) White pen ii) not a red pen
Answer:
Step-by-step explanation:
Firstly, find the total amount of pens
5 + 10 + 20 = 35, Total of 35 pens
White pens: 10/35
Not a red pen: 20 + 10= 30, 30/35
Calculate these to a percentage:
White- 10/35: 28.57%
Not a red pen- 30/35: 85.71%

Solve the following system of equations using the substitution method.
x=2y
2x+5y=9
x=
y=
Answer:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2

The volume in a single layer is 18 cubic centermeters. There are 5 layers in the rectangular prism. What is the volume in cubic centimeters of this rectangular prism
Answer:
the volume of the rectangular prism is 90 cm^2
Step-by-step explanation:
The computation of the volume of the rectangular prism is shown below:
Given that
The volume in a single layer is 18 cubic centimeters
And, there are 5 layers in the rectangular prism
So based on the above information
The volume of the rectangular prism is
= 5 ×18 cubic centimeters
= 90 cm^2
Hence, the volume of the rectangular prism is 90 cm^2
Can someone help me please brainliest for the correct answer
ok, So we know the length of 4/6 of the sides.....the ones we know are:
-4ft
-3ft
-9ft
-10ft
now to find the two missing sides.......we can see that one side is 5 because the other half is 4 ....which we already counted,.... (I'm talking about the unmeasured side over 9ft). Now to find the second...(the one closer to 10) since the already counted side is three and it's over 10 it has to be 7. so our missing ones are:
-7ft
-5ft
Now to add them together:
4+3+9+10+7+5=38
Lastly: REMEMBER TO ADD THE UNIT OF MEASUREMENT!!! Feet!!
That makes our answer 38ft!!
This means answer D or the last one is correct!!
HOPE I HELPED!!! HAVE AN AMAZING DAY/NIGHT!!!! PLEASE GIVE ME BRAINLIEST IF I HELPED YOU!!!
Answer:
38 feet.
Step-by-step explanation:
The length of the unmarked vertical side is 10 - 3 = 7 feet.
The length of the unmarked horizontal side is = 9 - 4 = 5 feet.
The perimeter = sum of the lengths of the sides
= 10 + 4 + 7 + 5 + 3 + 9
= 38 feet.
The measure of two angles are (3x+50) and (4x - 10). What must be true
about the angles if x = 20? What is the sum of their measures?
Answer: The two angles add up to 180 so they are supplementary angles.
The sum of their measures is 180 degrees.
Step-by-step explanation:
Plug in given value for x.
x=20
(3x+50)=
(60+50)=110
110
(4x-10)=
80-10=70
70

the edge of a tile is trimmed to make it fit along the edge of the shower. the diagram shows the angles that was cut. what is the value of x?
Answer:
x° = 77.7°
Step-by-step explanation:
We know that the interior angles within a quadrilateral add up to 360 degrees. We are provided with two right angles and a third angle of 102.3°. So we must solve to find x.
90 + 90 = 180
102.3 + 180 = 282.3
360 - 282.3 = 77.7
x = 77.7 degrees

(4/x) + (4/y) / (16/x2y2) is where we start. I will factor out
1/(16/x2y2).
(1/(16/x2y2)) (64xy2 + 4/y) = (x2y2/16)(64xy2 + 4/y)
I need to factor out a 4/y from there.
(x2y/4)(16xy + 1) = x2y (16xy + 1) / 4

Which of these correctly rearranges the terms in this polynomial so like terms are next to each other
Question is not complete, so i have attached it.
Answer:
B: -2x² - 6x² - 6x + 3x + 3 + 2
Step-by-step explanation:
From the image attached, the given polynomial is;
3 - 6x - 2x² + 3x - 6x² + 2
For like terms to be next to each other, we have to rearrange it as follows;
-2x² - 6x² - 6x + 3x + 3 + 2
Like terms are x² and x, thus they are now arranged next to each other.

m∠A = 50°, c = 25, a = 19, m∠C=?
Using the Sine Law
Answer:
m<C can not be computed
Step-by-step explanation:
m∠A = 50°, c = 25, a = 19, m∠C=?
Using the Sine Law
a/sin m<A = c/sin m<C
Substitute the given values
19/sin50 = 25/sinC
19sinC = 25sin50
19sinC = 19.1511
sinC = 19.1511/19
sinC = 1.0079
C = arcsin1.0079
Hence m<C can not be computed
