Hi There

Your answers are:

4) 12/3

-10) YES!

0/10) 0 (zero)

2 & 3/4 ) 11/4

10 & 1/2 ) 21/2

-.16) -4/ 25

3.17) 3 & 17 /100

.3 repeating ) YES

.16 repeating) 1/ 6

-1.2 repeating ) YES!

If a decimal does not terminate or repeat is is not a rational number

Step-by-step explanation:

For 4)

4/1 = 12/x

Ask yourself, how do i get from 4 to 12?

Multiply by 3! HOWEVER, whats done to the numerator MUST be done to the denominator!

4/1 * 3/3 = 12/3

For -10 )

-10/1 = -20/2

Simplify -20/2!

Divide -20 by 2 = -10

-10/1 = -10/1 YES!

For 0/10 )

When you have ZERO tenths, what does that equal? Zero!

For 2 & 3/4ths )

To change to an improper fraction, multiply the 2 by the denominator and add that to the numerator. Put that over the original denominator

(2*4 +3) / 4

8+3 / 4 = 11/4

For 10 & 1/2 )

Repeat what you did for 2& 3/4ths!

(10*2+1)/2

Answers

Answer:G=1/4 or the same as g=0.25

Step-by-step explanation:

Answer:

1/4 is the answer.

Step-by-step explanation:

So first, you subtract the g-9g. You get -2 = -8g, correct?

Next, you divide -2 by -8, you then get -2/-8

This simplifies to 1/4.

The roots of the equation x^2+bx+c=0 are −4 and 2. Find b.

Answers

first, love the killua profile picture ! i love hunterxhunter i am currently on season 5, episode 44 or 45 aka 119 or 120 but anyways,

answer:

b = 2

step-by-step explanation:

because its roots are -4 and 2,

and a = 1 [The coefficient of [tex]x^2[/tex]] we know that [tex]x^2 + bx + c = (x - (-4)) (x-2)=(x+4)(x-2) = 0.[/tex]

using the distributive property we get,

[tex]x^2 + 2x - 8 = 0.[/tex]

by equating coefficients (common strategy for partial fractions and undetermined coefficient method of solving ODE), we get b = 2 and c = -8 ( solved c just for fun guess :) ) .

Ian walks down a sloped path. After 6 minutes, he is 3 m above street level. Write the equation in slope-intercept form of the line that represents Ian’s height above street level, y, over time x, if he knows the path is parallel to another path with equation y = -2/3x + 12

Answers

Answer:

y=-2/3x+7

Step-by-step explanation:

Since you know the path is parallel to the equation y+-2/3x+12, you already know the slope is -2/3.

It says y is the height above street level, so that is 3. The problem says x is time, which is 6, so all you have to solve for is the y intercept.

3 (y, or the height above street level) = (-2/3) 6 (x, or time) + b (unknown y intercept)

3 = -4 + b

7 = b

So, y = -2/3x + 7

Multiply (−4)(−2)(−5)
A −40
B -8
C 8
D 40

Answers

The correct answer is A

Answer: A. -40

Step-by-step explanation:

-4 x -2 equals 8, 8 times -5 equals -40

Any negative number times another negative number equal a positive number. That number would be 8, but then you multiply 8 which is a possitive number by -5 which is a negative number you would get a negative number again (-40). Is it a trick question or something?

a triangle with vertices at a 20 -30 b 10 -15. and c 5 -20 has beem dilated with a center of dilation at the origin the image of b point b has coordinates 2 -3 what is the scale factor of the dilation​

Answers

Answer:

  1/5

Step-by-step explanation:

When the dilation is centered at the origin, the dilation factor is applied to each pre-image coordinate to get the image coordinate.

  k(10, -15) = (2, -3)

  k = 2/10 = -3/-15 = 1/5

The scale factor of the dilation is 1/5.

Can someone please help me with these 3 questions?

Answers

1) Since the angles are congruent, set them up to equal each other, then solve for x: x + 10 = 50. Now solve

2) Since angles AEC and DEB are congruent, set them up also to equal each other, then solve. : 6x + 20 = 10x. Now solve for x

3) Since AEC and DEB are congruent, they have the exact same angle measurement. Because of this, you are able to set the two equations equal to each other, then solve for x. After you have the value of x, you can plug it into  5x + 12 and solve once again, resulting in the answer for the measurement of angle AEC.

Write the equation of the line graphed below.

Answers

Answer:

In y intercept form, the equation would be: Y= -1/3x -6

Step-by-step explanation:

In order to find the equation, you can use any points given. In this case, I used (-6,-4) and (-3,-5).

With these points, you must find the slope. The change in our y values is -1 and the change in our x values is +3.

Now we have Y= -1/3x

To find the y intercept, you look on the graph for where there's a point that is lying on y line. In this case (0,-6) is lying on the y line. This means that the Y intercept for our equation is -6. Another example is (0,8), our y intercept would be 8 because the x value is 0!

In conclusion, our equation in y intercept form would be Y= -1/3x-6

If g(x) = 4x2 + 3x - 25, what is the value of g(-10)?
F -445
G 25
H 1545
J 345

Answers

Answer:

g(-10) = 345

Step-by-step explanation:

g(x) = 4x² + 3x - 25

~Substitute

g(-10) = 4(-10)² + 3(-10) - 25

~Simplify

g(-10) = 4(100) - 30 - 25

~Multiply

g(-10) = 400 - 30 - 25

~Subtract

g(-10) = 370 - 25

~Subtract

g(-10) = 345

3. Give the domain of y= √6-X using set builder notation.​

Answers

Answer:

{x | x ≤ 6}

Step-by-step explanation:

Given

y = √(6 - x)

Required

Determine the domain

We start by setting 6 - x to ≥ 0.

i.e.

6 - x ≥ 0

Add x to both sides

6 - x + x ≥ 0 + x

6 ≥ x

This can be rewritten as

x ≤ 6

Using set builder, the above van be represented as: {x | x ≤ 6}

Jordan Ellen recycle cans Jordan recycle seven cans for every 12 cans Ellen recycled last week how many total cans did Jordan and Ellis recycle last week.

Answers

Answer:

Ellen sold 42 cans and they sold 114 cans lastweek (both Ellen and Jordan)

Step-by-step explanation:

The oroginal ratio is 7:12 for every 12 cans ellen collects Jordan collects 7 so inorder to find the number of cans Ellen sold you have to figure out what 7 was multiplied by to get 42, and that would be 6. Then you multiply 12 by 6 and get 72 so ELlen sold 72 cans.

Now the new ratio is 42:72 when you add them together you get 114 so they sold (together) 114 cans last week.

Suppose that 20% of the subscribers of a cable television company watch the shopping channel at least once a week. The cable company is trying to decide whether to replace this channel with a new local station. A survey of 100 subscribers will be undertaken. The cable company has decided to keep the shopping channel if the sample proportion is greater than 0.27. What is the approximate probability that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20

Answers

Answer:

There is approximately 4% chance that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20.

Step-by-step explanation:

The random variable X can be defined as the number of subscribers of a cable television company who watch the shopping channel at least once a week.

X follows a Binomial distribution with parameters n = 100 and p = 0.20.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

1. np ≥ 10

2. n(1 - p) ≥ 10

Check the conditions as follows:

 [tex]np=100\times 0.20=20>10\\\\n(1-p)=100\times 0.80=80>10[/tex]

Thus, a Normal approximation to binomial can be applied.

[tex]\hat p\sim N(p,\frac{p(1-p)}{n})[/tex]

Compute the approximate probability that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20 as follows:

[tex]P(\hat p>0.27)=P(\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}>\frac{0.27-0.20}{\sqrt{\frac{0.20(1-0.20}{100}}})[/tex]

                   [tex]=P(Z>1.75)\\=1-P(Z<1.75)\\=1-0.95994\\=0.04006\\\approx 0.04[/tex]

Thus, there is approximately 4% chance that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20.
