Answer:

x = 11

Step-by-step explanation:

Given

[tex]\frac{3}{x-2}[/tex] = [tex]\frac{5}{15}[/tex] ( cross- multiply )

5(x - 2) = 45 ( divide both sides by 5 )

x - 2 = 9 ( add 2 to both sides )

x = 11

Answer:

-4

Step-by-step explanation:

Since they all have the same base;

Answer:

1080

Step-by-step explanation:

480 + 480 + 1/4(480) = 1080

Answer:

1080 postcards

Step-by-step explanation:

WIth 2 full albums you take 480 and multiply it by 2 to get 960 and 1/4 of 480 is 120 because we divide 480 by 4 to get that and if we add 120 to 960 we get 1080.

I would help but I don’t know what all of those symbols are.

Answer:

[tex]P(3) = 0.3397[/tex]

Step-by-step explanation:

The given details represent binomial distribution. So, we have:

[tex]n = 5[/tex]

[tex]p = 64\% = 0.64[/tex]

Required

Calculate P(3)

This is calculated using:

[tex]P(x) = ^nC_x * p^x * (1- p)^{n-x}[/tex]

This gives:

[tex]P(3) = ^5C_3 * 0.64^3 * (1- 0.64)^{5-3}[/tex]

[tex]P(3) = 10 * 0.64^3 * 0.36^2[/tex]

[tex]P(3) = 0.3397[/tex]

Answer:

Undefined.

Step-by-step explanation:

Slope is equal to the change in y over the change is x, or rise over run.

[tex]m=\frac{change in y }{ change in x}[/tex]

The change in x is equal to the difference in x-coordinates, and the chnage in y is equal to the difference in y-coordinates.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Substitute in the values of x and y into the equation to find the slope.

[tex]m= \frac{-2-(2)}{2-(2)}[/tex]

Simplify it. since -2-(2) and 2-(2) = nothing, the Slope is Undefined.

Hence, the slope is Undefined.

Answer:

Undefined

Answer:

$9.38

Step-by-step explanation:

halibut is measured in pounds and a portion is measured in ounces

in order to determine the cost, the two units have to be comparable. So, ounces have to be converted to pounds

1 ounce = 0.0625 pounds

6 ounces = 0.0625 x 6 = 0.375 pounds

0.375 pounds would cost 0.375 pounds x 25 pounds = $9.38

Answer:

149 tickets

Step-by-step explanation:

just simple division-

1112/7.50= 148.27

so, 148 tickets would not quite do it- they'd have to sell 149

Answer:

52 times

Step-by-step explanation:

Given

[tex]n = 78[/tex] -- Number of times

Required

Determine the expected times to get > 2.

In a fair dice, the outcome > 2 are:

[tex]>2 = \{3,4,5,6\}[/tex]

The probability of the above is:

[tex]p = \frac{4}{6}[/tex]

[tex]p = \frac{2}{3}[/tex]

The number of times is calculated using:

[tex]E(x) = n * p[/tex]

[tex]E(x) = 78* \frac{2}{3}[/tex]

[tex]E(x) = \frac{78* 2}{3}[/tex]

[tex]E(x) = \frac{156}{3}[/tex]

[tex]E(x) = 52[/tex]

Answer:

Step-by-step explanation:

Perimeter of the triangular base = 10 + 10 + 16

                                                      = 36 ft

Height of the prism = 15 ft

Base area = Area of the triangle

                 = [tex]\frac{1}{2}(\text{Base})(\text{Height}})[/tex]

                 = [tex]\frac{1}{2}(16)(6)[/tex]

                 = 48 square ft

Surface area of the triangular prism = 2(base area) + (perimeter × height)

                                                            = 2(48) + 36(15)

                                                            = 96 + 540

                                                            = 636 square ft

Answer:

2 = 18, 3 = 73

Step-by-step explanation:

2) 22+140= 162

180-162= 18

x=18

(180 ‘cuz that’s the full angle of a triangle)

——————————————————————

3) the right angle is a 90 degree angle so

17+90=107

180-107=73

x=73

Answer:

A. Area of ABCD = 240 [tex]cm^{2}[/tex]

B. 60 cm

C. 36 cm

D. 50 cm

Step-by-step explanation:

Given: AB = 24cm BC = 10cm and AE = 13cm.

A.  Since a rectangle is a 2 dimensional figure, it has no volume but area.

So that,

the area of the rectangle ABCD = length x width

                                                     = 24 x 10

                                                     = 240 [tex]cm^{2}[/tex]

B. To calculate the circumference of the BCD triangle, apply the Pythagoras theorem to determine BD.

[tex]BD^{2}[/tex] = [tex]BC^{2}[/tex] + [tex]DC^{2}[/tex]

       = [tex]10^{2}[/tex] + [tex]24^{2}[/tex]

       = 676

BD = [tex]\sqrt{676}[/tex]

     = 26

BD = 26 cm

so that,

the circumference of BCD = 10 + 24 + 26

                                         =   60 cm

C. To calculate the circumference of the BEC triangle,

AC = 26 cm, AE = 13 cm

CE = 26 - 13

     = 13 cm

CE = 13 cm

The circumference of the BEC triangle = 13 + 13 + 10

                                                                 = 36 cm

D. The circumference of the DEC triangle = 13 + 13 + 24

                                                                 = 50 cm
