What is the measure of the unknown angle? 7 50° n​

Step-by-step explanation:

use -4y for x in the second equation

-4 y + 5 y = 2

so

y = 2

then x = -4(2) = -8

(-8 , 2)

Answer:

72 got you :) brainly?

Step-by-step explanation:

To show that the equations are the same, we need to rewrite one of the equations as an equivalent equation of the second

Damita's claim is true

The equations are given as:

0.8x - 0.8 = 1.6

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

We need to rewrite one of the equations, as follows:

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

Express as decimal

0.8 ( x - 1 ) = 1 + 0.6

Open the brackets

0.8x - 0.8 = 1.6

Now we have:

0.8x - 0.8 = 1.6 (the first equation) and 0.8x - 0.8 = 1.6 (the equivalent of the second equation)

The above shows that both equations are the same

Answer:

I'm pretty sure it's 0.08 km/minute

Step-by-step explanation:

r=4/50

4/50=0.08

Answer:

Step (1)

We know that the sum of all the terms in an infinite geometric sequence finding from following equation whenever |q| < 1 .

q = magnitude

[tex]s( \infty ) = \frac{t(1)}{1 - q} \\ [/tex]

So :

[tex]s( \infty ) = \frac{t(1)}{1 - q} \\ [/tex]

[tex]81 = \frac{t(1)}{1 - q} \\ [/tex]

[tex]81(1 - q) = t(1)[/tex]

Remember it I'll use it again.

_________________________________

Step (2)

We know that the sum of the n first terms of a geometric sequence finding from following equation.

[tex]s(n) = \frac{t(1) \times (1 - {q})^{n} }{1 - q} \\ [/tex]

_________________________________

Sum of all terms starting from the third is 9.

So :

[tex]s(2) + s(3 - \infty ) = 81[/tex]

[tex]s(2) + 9 = 81[/tex]

Sides minus 9

[tex]s(2) = 81 - 9[/tex]

[tex]s(2) = 72[/tex]

So :

[tex]t(1) + t(2) = 72[/tex]

[tex]t(1) + t(1) \times q = 72[/tex]

Factoring t(1)

[tex]t(1) \times (1 + q) = 72[/tex]

We have found t(1) = 81 ( 1 - q ) in step (1).

So :

[tex]81(1 - q)(1 + q) = 72[/tex]

Divided sides by 81

[tex](1 - q)(1 + q) = \frac{72}{81} \\ [/tex]

[tex](1 - q)( 1 + q) = \frac{8}{9} \\ [/tex]

[tex]1 - {q}^{2} = \frac{8}{9} \\ [/tex]

Subtract sides minus -1

[tex] - {q}^{2} = \frac{8}{9} - 1 \\ [/tex]

[tex] - {q}^{2} = \frac{8}{9} - \frac{9}{9} \\ [/tex]

[tex] - {q}^{2} = - \frac{1}{9} \\ [/tex]

Negatives simplifies

[tex] {q}^{2} = \frac{1}{9} \\ [/tex]

Radical sides

[tex]q = + \frac{1}{3} \\ q = - \frac{1}{3} [/tex]

_________________________________

Step (4)

If q = 1/3 :

[tex]81(1 - q) = t(1)[/tex]

[tex]81(1 - \frac{1}{3}) = t(1) \\ [/tex]

[tex]81( \frac{2}{3}) = t(1) \\ [/tex]

[tex]t(1) = 27 \times 2[/tex]

[tex]t(1) = 54[/tex]

So :

[tex]t(2) = t(1) \times q[/tex]

[tex]t(2) = 54 \times \frac{1}{3} \\ [/tex]

[tex]t(2) = 18[/tex]

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

If q = - 1/3 :

[tex]81(1 - q) = t(1)[/tex]

[tex]81(1 - ( - \frac{1}{3})) = t(1) \\ [/tex]

[tex]81(1 + \frac{1}{3}) = t(1) \\ [/tex]

[tex]81( \frac{4}{3}) = t(1) \\ [/tex]

[tex]t(1) = 27 \times 4[/tex]

[tex]t(1) = 108[/tex]

So :

[tex]t(2) = t(1) \times q[/tex]

[tex]t(2) = 108 \times - \frac{1}{3} \\ [/tex]

[tex]t(2) = - 36[/tex]

Answer:

-12

Step-by-step explanation:

y = mx + b

the one being multiplied  to x is the slope

Answer:

slope: -12

y-intercept: 7

Step-by-step explanation:

The slope-intercept form of the equation of a line is

y = mx + b

where m = slope, and b = y-intercept.

Your equation is

y = -12x + 7

Your equation is already in the slope-intercept form.

m = -12

b = 7

slope: -12

y-intercept: 7

Answer:

The critical value  is  [tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  15

   The  level of significance is  [tex]\alpha = 0.10[/tex]

The null hypothesis is  [tex]H_o : \mu _1 = \mu_2[/tex]

The alternative hypothesis is  [tex]H_a : \mu_1 \ne \mu_2[/tex]

Here [tex]\mu_1[/tex] is average time for previous year

        [tex]\mu_2[/tex] is the average time for current year

Generally the degree of freedom is mathematically represented as

         [tex]df = n -1[/tex]

=>      [tex]df = 15 - 1[/tex]

=>     [tex]df = 14[/tex]

Generally from the student  t distribution table the critical value  for [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of  [tex]df = 14[/tex] for a two tailed test  is  

      [tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]

Answer:

3rd option

Step-by-step explanation:

to find the x- intercept let y = 0 in the equation and solve for x

2x - 3(0) = - 12

2x  - 0 = - 12

2x = - 12 ( divide both sides by 2 )

x = - 6 ← x- intercept

To find the y- intercept let x = 0 in the equation and solve for y

2(0) - 3y = - 12

0 - 3y = - 12

- 3y = - 12 ( divide both sides by - 3 )

y = 4 ← y- intercept

Answer:

y(x) = c_1 e^(-1/(2 x^2))

Step-by-step explanation:

Solve the separable equation x^3 (dy(x))/(dx) - y(x) = 0:

Solve for (dy(x))/(dx):

(dy(x))/(dx) = y(x)/x^3

Divide both sides by y(x):

((dy(x))/(dx))/y(x) = 1/x^3

Integrate both sides with respect to x:

integral((dy(x))/(dx))/y(x) dx = integral1/x^3 dx

Evaluate the integrals:

log(y(x)) = -1/(2 x^2) + c_1, where c_1 is an arbitrary constant.

Solve for y(x):

y(x) = e^(-1/(2 x^2) + c_1)

Simplify the arbitrary constants:

Answer:  y(x) = c_1 e^(-1/(2 x^2))

Answer:

Step-by-step explanation:

990 = 1000 - 10

so 3 x 990 = 3 x (1000 - 10) = 3 x 1000 + 3 x (-10) = 3000 - 30 = 2970

and

990 = 900 + 90

so 3 x 990 = 3 x (900 + 90) = 3 x 900 + 3 x 90 = 2700 + 270 = 2970

Answer:

$13.95

Step-by-step explanation:

$166.29 ×12/100

=$13.95 will be the tip.

Answer:

$13.95

Step-by-step explanation:

Convert the 12% to an actual number that can be used in a calculator. For percents, this is done by dividing the percent (in this case 12%) by 100%.So, the conversational term "12%" becomes 12% / 100% = 0.12 in terms of a real mathematical number. Then you need to find out what 12% of your $116.29 meal cost is.This is always done by multiplying 0.12 by $116.29, or 0.12 x $116.29=$13.95.

Answer:

0.01 (nearest hundredth)

Step-by-step explanation:

[tex]\mathsf{probability=\dfrac{number \ of \ favorable \ outcomes}{number \ of \ total \ outcomes}}[/tex]

Total number of marbles (total outcomes) = 2 + 6 + 7 = 15

⇒ Probability of the first marble being red = [tex]\dfrac{2}{15}[/tex]

As there is no replacement, the total number marbles is now 15 and there is only 1 red marble left.

⇒ Probability of the second marble being red = [tex]\dfrac{1}{14}[/tex]

So the probability of the 1st and 2nd marble being red is:

[tex]\dfrac{2}{15}\times \dfrac{1}{14} = \dfrac{1}{105}[/tex]  = 0.01 (nearest hundredth)
