Step-by-step explanation:

Answer:

  (4, -3) is the center

Step-by-step explanation:

The equation ...

  16x^2 +25y^2 -128x +150y +81 = 0

can be rearranged by completing the square(s) to ...

  (4x -16)^2 +(5y +15)^2 = 400

Dividing by 400 gives ...

  (x -4)^2/5^2 +(y +3)^2/4^2 = 1

This is the equation of an ellipse centered at (4, -3) with major axis 10 and minor axis 8.

It would take 5 hours.

1/15 of the lawn in 1/3 hours means it takes 1 hour to water 3/15 of the lawn aka 1/5

1/5 of the lawn in 1 hour would mean it takes 5 hours to finish watering the entire lawn.

Answer:

151 meters

Step-by-step explanation:

6946/46=151 meters

Answer:

Step-by-step explanation:

If you want to be formal, let the shorter bridge = x

46x = 6946                  Divide by 46

x = 6946/46

x = 151

So the shorter bridge is 151 meters long.

Answer:

158

Step-by-step explanation:

We know the supplement of angle 6 is 22, due to the fact that they are corresponding angles. Simply subtract 22 from 180 to get the answer. 180-22=158

Answer:

158 degrees

Step-by-step explanation:

Angle 6 has a same side interior relationship with the 22 degrees, so the sum of these angles are equal to 180 degrees.

To find the missing angle, subtract 180 by 22 degrees.

180-22= 158

Answer:

D

Step-by-step explanation:

n = 5

an = 176

an = a1*x^(n -1)

a5 = a1 * x^4 = 176

a7 = a1 * x^6 = 704

a7/a6 = a1 * x^6 / a1*x^4 = 704 / 176

Cancel out a1

x^6/x^4 = 704/176      Divide numerator and denominator by 176

x^2 = 4                        Take the square root of both sides

x = 2 or - 2

176 = a1 * x^4

176 = a1 * 16

a1 = 11

a1 is going to be 11 whether x is 2 or minus 2.

hi mallllll. hehehe

once again its [tex]a_{1} = -11[/tex]

Answer:

Infinitely many solutions

Step-by-step explanation:

6(2x + 4) = 3(4x + 8)

Distribute the 6

6 * 2x = 12x and 6 * 4 = 24

12x + 24 = 3(4x+8)

Distribute the 3

3 * 4x = 12x and 3 * 4 = 24

12x + 24 = 12x + 24

On both sides of the equal sign we have 12x + 24.

When both sides are equal there are infinitely many solutions.

Who's Joe? I am in dire need of therapy.

Answer:

open the brackets

mx+mn=n

mx=n-mn

since we want to know the value of x , then we divide both sides with m ,thus giving us

x=n/m - n

Answer:

x = [tex]\frac{n-mn}{m}[/tex]

Step-by-step explanation:

m(x + n) = n ← distribute parenthesis on left side by m

mx + mn = n ( subtract mn from both sides )

mx = n - mn ( isolate x by dividing both sides by m )

x = [tex]\frac{n-mn}{m}[/tex]

well, the numeric difference will be 136 - 80 = 56, now, if we take 80 (original price) to be the 100%, what is 56 (the increase) in percentage off of it?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 80&100\\ 56&x \end{array}\implies \cfrac{80}{56}=\cfrac{100}{x}\implies \cfrac{10}{7}=\cfrac{100}{x} \\\\\\ 10x=700\implies x = \cfrac{700}{10}\implies x = \stackrel{\%}{70}[/tex]

Answer:

Answer:

  9.89×10^-9

Step-by-step explanation:

  0.000 000 009 89 = 9.89×10^-9

__

We have introduced spaces in the number to make the digits easier to count. (Some technical publications will write the number with thin spaces for just that reason.) The most-significant digit is in the 9th place to the right of the decimal point, so has a place value of 10^-9.

16x - 7 = 15x

16x - 15x = 7

x = 7

------------------------

7 * 15 = 105° your answer

Answer:

79

over

2000 or 79/2000 or 3.95%

Step-by-step explanation:

The probability that one of this​ manufacturer's cars was manufactured at plant A and has a defective emissions control​ device is 6.33%.

Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.

Given, An automobile manufacturer produces 79​% of its cars at plant A and 5​% of the cars manufactured at plant A have defective emissions control​ devices.

∴ The probability that one of this​ manufacturer's cars was manufactured at plant A and has a defective emissions control​ device is,

= (5/79)×100%.

= 6.33%.

Answer:

=============================================================

Explanation:

The letter O looks very similar to the number zero, so I'm going to use other letters to avoid confusion. For the smaller circle on the left, it'll have center P. The circle on the right will have center Q. See the diagram below.

Based on that, we can say that PQ = 20 cm.

Let x = length of PK

PK + KQ = PQ

KQ = PQ - PK

KQ = 20 - x

We'll keep this in mind for later. I'll refer to this as "Fact 1" when it does come up later.

------------------------

We're given this equation

3AK=2BK

Let's get the numbers to one side and the letters to the other side like so:

3AK=2BK

3AK/BK = 2

AK/BK = 2/3

We'll use this later as well.  I'll refer to this as "Fact 2" when it does come up later.

------------------------

Next, draw a segment from P to A to form triangle PAK (also shown in the diagram below). Do the same for points Q and B to form triangle QBK.

The segments PA and PK are radii of the smaller circle, so PA = PK which leads to triangle PAK being isosceles. Triangle QBK is also isosceles for similar reasoning.

The angles AKP and QKB are vertical angles, so they are congruent.

The facts mentioned so far boil down to the two triangles being similar triangles (use the angle angle method to prove).

------------------------

Now that we know the triangles are similar, we can use a proportion to solve for x.

PK/KQ = AK/KB

PK/KQ = 2/3  .... use fact 2

x/(20-x) = 2/3 .... use fact 1

3x = 2(20-x) .... cross multiply

3x = 40 - 2x

3x+2x = 40

5x = 40

x = 40/5

x = 8

So,

The radius of the smaller circle on the left is 8 cm.

The radius of the larger circle on the right is 12 cm.
