20 POINTS PLZ HELP
What would the equation y = -2x + 24 look like when graphed?

It would be a straight line.
It would be a curve.
It would be a parabola.
It would be a triangle.

Answer:

8.94 if no rounding is necessary.

Step-by-step explanation:

Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...

8² + b² = 12²

64 + b² = 144

Subtract 64 from both sides...

64 - 64 + b² = 144 - 64

b² = 80

[tex]\sqrt{80}[/tex] = 8.94 if you're not rounding.

Answer:

150

Step-by-step explanation:

100%/ x% = 219/ 416

Cross multiply

x = 150 %

219 is 150% of 416

Answer:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form:(30/19,2/19)

Equation Form: x=30/19, y=2/19

Disclaimer: I'm not sure because the numbers are too blurry. If my numbers don't match yours, just replace them in my work and recalculate them.

1) not tangent

2) tangent

3) not tangent

Step-by-step explanation:

If they are tangent, the triangles formed will be right triangles.

Check using the Pythagorean theorem:

1) 18² = 14.4² + 11.7²

324 = 207.36 + 136.89

324 ≠344.25       not tangent  

2) 7.5² = 4.5² + 6²

56.25 = 20.25 + 36

56.25 = 56.25     tangent

3) 20² = 12² + 12²

400 = 144 + 144

400 ≠ 288        not tangent

Step-by-step explanation:

Area of the triangle is

= 1 /2 * base * height

= 1 /2 * 22 * 13

= 143 square kilometers

Hope it will help :)❤

Answer:

58.5

Step-by-step explanation:    

( (22 * 13) / 2 ) - ( (13 * 13) / 2 ) = ( 286 / 2 ) - ( 169 / 2 ) = 143 - 84.5 = 58.5

Answer:

he save last month $33.25

Step-by-step explanation:

Let us assume last month saving be x

This month saving be 3x + $8

And, the total would be $141

So based on the above information

The equation is

x + 3x + $8 = $141

4x + $8 = $141

4x = $141 = $8

4x = $133

x = $33.25

Hence, he save last month $33.25

Therefore the same is relevant

Answer:

Step-by-step explanation:

(15x8x2)+(15x6x2)+(6x8x2)=516m

A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.

The number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.

A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.

We have,

The amount of dog food in the bag = 2/3

The amount of dog food the dog eats per week = 4/9

We need to find the number of weeks that the dog finishes 2/3 of dog food.

The number of weeks:

1 week = 4/9 dog food

Multiply both sides by (9/4 x 2/3)

(9/4 x 2/3) x 1 week = (9/4 x 2/3) x 9/4 dog food

3/2 weeks = 2/3 dog food

[ 3/2 = 1 (1/2) ]

1(1/2) weeks = 2/3 dog food

This means in one and a half weeks the dog finished 2/3 of dog food.

Thus the number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.

Answer: 7.8

Explanation: 8.9 - 2.9 = 6.0 + 1.8 = 7.8

Answer:

Kayla,  learn this,  :D  more math is based on it.  Just learn it, just memorize the following

Step-by-step explanation:

m = slope

m = rise / run

m = y2 - y1   /  x2 - x1       ( this is still rise over run but in point form )

they give us two points to plug into the above formula

P1 = (-4, 8 )  in the form of ( x1, y 1 )

P2 = (2, -1)  in the form of (x2, y2 )

now plug those into the above formula

m = ( -1 - 8 ) / ( 2-(-4) )

m = -9  /  ( 2 + 4 )

m = -9 / 6

m = - 3/2

since we know the slope now  , we can use the point slope equation of

y - y1 = m ( x - x1)

use the m we found and either point  , P1 or P2

y - 8 = -3/2(x -(-4) )

y-8 = -3/2(x + 4)

y-8 = -3/2x - 6

y = -3/2x -6 + 8

y = -3/2x + 2

there you go  :)

Answer:

The required sample size is 329.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money.

This means that [tex]\pi = 0.31[/tex]

Confidence level is not given, so we assume 95%.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

What is the required sample size if you want to estimate this proportion with a margin of error of 0.05?

We need a sample size of n. n is found when M = 0.05. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.05 = 1.96\sqrt{\frac{0.31*0.69}{n}}[/tex]

[tex]0.05\sqrt{n} = 1.96\sqrt{0.31*0.69}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.31*0.69}}{0.05}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.31*0.69}}{0.05})^2[/tex]

[tex]n = 328.6[/tex]

Rounding up

The required sample size is 329.
