What is 4/6 times 9 I need this

Answer:

YES

Step-by-step explanation:

(3/8)·64 = 24 seats in the first class carriage are being used.

(7/13)·(78)·3 = 126 seats in the standard carriages are being used, for a total of ...

 24 + 126 = 150 . . . occupied seats

The number of available seats is ...

 64 +3·78 = 298

so half the seats on the train will be 298/2 = 149 seats.

 150 > 149, so more than half the seats on the train are being used.

I need help with this please graphing is too complicated. If anyone can help I would be very happ.

Answer:

C. Solving this equation results in the statement -48 = 48. Because this is a false statement, the equation has no solution.

Step-by-step explanation:

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

24x - 48 = 24x + 48

minus 24x from both sides and you get -48 = 48

A false statement means one side does not equal the other. False statement always means no solution

you can solve this equation for x, but looking at the answers it's not what the question is asking for

Answer:

5 cm

Step-by-step explanation:

Volume of a cylinder = π*radius^2*height

675π = π * radius^2 * 27

radius^2 = 25

radius = 5 cm

Answer:

Step-by-step explanation:

V=pi x r^2 x h

r^2 = 675pi / (pi x 27) = 25

r = 5

Answer:

C. 116

Step-by-step explanation:

Find where the two curves intersect:

y = 6x - 2x ²

y = x ²

6x - 2x ² = x ²   →   3x ² - 6x = 3x (x - 2) = 0   →   x = 0 and x = 2

Now, for a shell of radius x units away from the axis of revolution, the height of the shell would be the vertical distance between the upper curve and the lower curve. For 0 ≤ x ≤ 2, we have 6x - x ² ≥ x ², so the height of any given shell is (6x - x ²) - x ² = 6x - 2x ².

Then volume of the solid is

[tex]\displaystyle 2\pi \int_0^2 x(6x-2x^2)\,\mathrm dx = 2\pi \left(2x^3-\frac{x^4}2\right)\bigg|_0^2 = \boxed{16\pi}[/tex]

J. 19.7

Step-by-step explanation:

SOH(sine = opposite side/hypotenuse) CAH TOA

sin 80° = RS/20

=> 0.985 = RS/20

=> RS = 20 × 0.985 = 19.7

Answer:

-10x

Step-by-step explanation:

multiply -5 with 2x

-5×2x= -10x

Answer:

Basically, you have to multiply the term at the top with the one on the left of the corresponding box. In this case you have to multiply -5 with 2x.

Answer:

y=(x-4)(x-1)

Step-by-step explanation:

We need y to be 0 and x must equal 4 and 1

The only way to make y=0

is to swap 9 and 5 for -4 and -1

This is the inequality

2x + 5y ≥ 90

Answer:

[tex] x = \dfrac{10}{3}~~or~~x = -2 [/tex]

Step-by-step explanation:

(x,−1) and (4x−2,5) is 10

[tex] \sqrt{(4x - 2 - x)^2 + (-1 - 5)^2} = 10 [/tex]

[tex] (3x - 2)^2 + (-6)^2 = 100 [/tex]

[tex] 9x^2 - 12x + 4 + 36 = 100 [/tex]

[tex] 9x^2 - 12x + 40 = 100 [/tex]

[tex] 9x^2 - 12x - 60 = 0 [/tex]

[tex] 3x^2 - 4x - 20 = 0 [/tex]

[tex] 3x^2 - 10x + 6x - 20 = 0 [/tex]

[tex] x(3x - 10) + 2(3x - 10) = 0 [/tex]

[tex] (3x - 10)(x + 2) = 0 [/tex]

[tex] x = \dfrac{10}{3}~~or~~x = -2 [/tex]

Answer:

  D.  6

Step-by-step explanation:

The height of the larger cylinder is 15/5 = 3 times the height of the smaller one. Because the cylinders are similar, you know that the radius of the larger one will have the same multiplier of the radius of the smaller one.

The larger radius is 3 × 2 = 6.

Answer:

[tex]{\huge\blue{\fbox{{࿐αɴѕωєя࿐}}}}[/tex]

[tex]6(3 + 4) = 6(3) + 6(4) \\ 6(7) = 6(3) + 6(4) \\ 6 \times 7 = 6 \times 3 + 6 \times 4 \\ 42 = 18 + 24 \\ 42 = 42[/tex]

→ LHS = RHS

Answer:

H0 : μD = μN

H0 : μD > μN

Test statistic = 2.192

Pvalue = 0.017

there is strong evidence that healthy adult eat more cookies for a snack when they are distracted with a computer game during lunch than when they are not.

Step-by-step explanation:

Given the data:

n1 = 22 ; x1 = 52.1 ; s1 = 45.1

n2 = 22 ; x2 = 27.1 ; s2 = 26.4

H0 : μD = μN

H0 : μD > μN

The test statistic :

(x1 - x2) ÷ (Sp*√(1/n1 + 1/n2))

Sp = (n1 - 1)s1² + (n2 - 1)s2²] ÷ (n1 + n2 - 2)

Sp = √[((21 * 45.1^2) + (21 * 26.4^2)) ÷ 42]

Sp = 36.952469

Test statistic :

(52.1 - 27.1) ÷ Sp * √(1/21 + 1/21))

25 ÷ (36.952469 * 0.3086066)

25 ÷ 11.4037758196954

Test statistic = 2.192

Using the Pvalue from Test statistic calculator :df = 42, Tscore = 2.192

Pvalue = 0.017

α = 0.05

Pvalue < α

Hence, there is strong evidence that healthy adult eat more cookies for a snack when they are distracted with a computer game during lunch than when they are not.

Answer:

y = 4x - 6

Step-by-step explanation:

Given the following data;

Slope, m = 4

Intercept, c = -6

To write the equation of line in the slope-intercept form;

The standard equation of straight line is given by the formula;

y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Substituting the values, we have;

y = 4x + (-6)

y = 4x - 6
