Answer:

3/4

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan X = opp side / adj side

tan X = 24/32

tan X = 3/4

Answer:

tan X = 24/32

Step-by-step explanation:

Using SOH-CAH-TOA, we can figure out tan X.

To find tan. the equation is opposite over adjacent.

So, tan X = 24/32.

Answer:

  24.6%

Step-by-step explanation:

The cost of the ticket in euros is ...

  £222 × €1.38/(£1) = €306.36

Then the ratio of the tax to the to the total cost is ...

  €100/(€306.36 +100) = 100/406.36 ≈ 24.6%

Answer:

Step-by-step explanation:

Use this formula:

[tex]A(t)=P(1+\frac{r}{n})^{nt}[/tex] where A(t) is the amount after the compounding is done, P is the initial investment (our unknown), r is the interest rate in decimal form, n is the number of compoundings per year, and t is the time in years. Filling in:

[tex]520=P(1+\frac{.03}{12})^{(12)(3)}[/tex] and simplifying that a bit:

[tex]520=P(1+.0025)^{36[/tex] and a bit more:

[tex]520=P(1.0025)^{36[/tex] and even  bit more:

520 = P(1.094551401) and divide to get

P = $475.30

2.81 7.8961

2.82 7.9524

2.83 8.0089

Answer:

hypotenuse ≈ 44 inches

Step-by-step explanation:

Using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other two sides.

let the hypotenuse be h , then

h² = 23² + 38² = 529 + 1444 = 1973 ( take square root of both sides )

h = [tex]\sqrt{1973}[/tex] ≈ 44 inches ( to the nearest inch )

Answer:

b₂ = 5

Step-by-step explanation:

Substitute the given values into the formula

16 = [tex]\frac{1}{2}[/tex] × 4 × (3 + b₂)

16 = 2(3 + b₂) ( divide both sides by 2 )

8 = 3 + b₂ ( subtract 3 from both sides )

5 = b₂

Step-by-step explanation:

V=1/3 × πr²h

since H=6, R=4

V= π×(4)²×(6)/3

V=96π/3

V=32π

Note: ( we are not given the pie (π) value )

Answer:

Step-by-step explanation:

r = 4

h = 6

pi = 3.14

Formula

V = 1/3 pi r^2 h

V = 1/3 3.14 * 4^2 * 6

V = 1/3 * 3.14 * 16 * 6

V = 100.48

Answer:

TV = 6

Step-by-step explanation:

The distance from the vertex to the centroid is twise the distance from the centroid to the midpoint, then

JV = [tex]\frac{1}{2}[/tex] TJ = [tex]\frac{1}{2}[/tex] × 4 = 2

Then

TV = TJ + JV = 4 + 2 = 6

You want to find Pr[-2 < Z < -1].

The table tells you that

• Pr[Z < 0] = 0.5000

• Pr[Z < 1.00] = 0.8412

• Pr[Z < 2.00] = 0.9772

• Pr[Z < 3.00] = 0.9987

We have

Pr[-2 < Z < -1] = Pr[Z < -1] - Pr[Z < -2]

(because the distribution of Z is continuous)

… = Pr[Z > 1] - Pr[Z > 2]

(by symmetry of the distribution about its mean)

… = (1 - Pr[Z < 1]) - (1 - Pr[Z < 2])

(by definition of complement)

… = Pr[Z < 2] - Pr[Z < 1]

… = 0.9772 - 0.8412

… = 0.1360 ≈ 0.14 … … … (B)

Complete question is;

A soccer ball was kicked through the air and it followed the path. Let h(s) = −3s² +75 represent the height of the soccer ball after s seconds.

Find the time at which the soccer ball hits the ground.

Answer:

s = 5 seconds.

Step-by-step explanation:

We are given the function;

h(s) = −3s² +75

Where;

h(s) is height at time s

s is the time taken

Now, the time at which the time at which the soccer ball hits the ground would be at h(s) = 0 since height is at 0 point.

Thus;

−3s² +75 = 0

−3s² = -75

s² = 75/3

s² = 25

s = √25

s = 5 seconds.

Answer:

(B). 51°

Step-by-step explanation:

Solution :

Given :

[tex]$P'(x) = -0.0008x^3+0.20x^2+46.8x,$[/tex]    for x ≤ 200

Total profit when 120 members are enrolled is :

[tex]$\sum_{i=1}^6P'(x_i) \Delta x$[/tex]      with [tex]\Delta x = 20[/tex]

Using the left end points, we get,

The values of [tex]x_i[/tex] are : { 0, 20, 40, 60, 80, 100}

Therefore,

[tex]$P'(x_1) = P'(0)=-(0.0008)(0)^3+(0.20)(0)^2+(46.8)(0)$[/tex]

                        = 0

[tex]$P'(x_2) = P'(20)=-(0.0008)(20)^3+(0.20)(20)^2+(46.8)(20)$[/tex]

                          = 1009.6

[tex]$P'(x_3) = P'(40)=-(0.0008)(40)^3+(0.20)(40)^2+(46.8)(40)$[/tex]

                         =  2140.8

[tex]$P'(x_4) = P'(60)=-(0.0008)(60)^3+(0.20)(60)^2+(46.8)(60)$[/tex]

                         = 3355.2

[tex]$P'(x_5) = P'(80)=-(0.0008)(80)^3+(0.20)(80)^2+(46.8)(80)$[/tex]

                         = 4614.4

[tex]$P'(x_6) = P'(100)=-(0.0008)(100)^3+(0.20)(100)^2+(46.8)(100)$[/tex]

                           = 5880

[tex]$\sum_{i=1}^6P'(x_i) \Delta x = P'(x_1)\Delta x + P'(x_2)\Delta x + P'(x_3)\Delta x + P'(x_4)\Delta x + P'(x_5)\Delta x + P'(x_6)\Delta x $[/tex]  

= (0)(20) + (1009.6)(20) + (2140.8)(20) + (3355.2)(20) + (4614.4)(20) + (5880)(20)

= (20)( 0 + 1009.6 + 2140.8 + 3355.2 + 4614.4 + 5880)

= (20)(17,000)

= 340,000 cents

[tex]$=\frac{340000}{100} \ \text{dollars}$[/tex]

= 3400 dollars

Hence, the required total profit is 3400 dollars.

Answer:

because they are both in the circle

Step-by-step explanation:

Answer:

The perimeter 9+9+15+4+3+4pi=52.56 units.

The area is 25.12+135 which is 160.12 unit squared.

Step-by-step explanation:

Perimeter of this shape = perimeter of half circle + perimeter of the rectangle

Diameter of circle = 15-4-3 = 8

Radius of circle = 8/2 = 4

Perimeter of the shape = (2 x pi x 4)/2 + 15 + 9 + 9 + 4 + 3

   = 4pi + 40 = 52.56 units     (substitute pi = 3.14)

Area of shape = area of half circle + area of rectangle

= (pi x 4 x 4)/2  + (9 x 15)

= 25.12 + 135 = 160.12 unit squared

Answer:

14

Step-by-step explanation: B is the midpoint of AC, in other words it is the halfway point.

So A to B should be equal to B to C

Our expression is:

2x + 9 = 37

Subtract 9

2x = 28

Divide by 2

x = 14

Answer:

The correct answer is 2043 km².

Step-by-step explanation:

Given:

Starting area,

A = 2300 km²

Rate of decreasing,

r = 5.75%

Time,

t = 12 years

As we know,

⇒ [tex]y = A(1-r)^t[/tex]

By substituting the values, we get

      [tex]=2300(1-0.0575 )^{12}[/tex]

      [tex]=2300(0.9425)^{12}[/tex]

      [tex]=2300\times 0.8883[/tex]

      [tex]=2043 \ km^2[/tex]

Answer:

x = 4

Step-by-step explanation:

The line DE is parallel to AC and divides the sides proportionally, that is

[tex]\frac{BD}{AD}[/tex] = [tex]\frac{BE}{CE}[/tex] , substitute values

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

3x = 2(x + 2) = 2x + 4 ( subtract 2x from both sides )

x = 4

Answer: [tex]8d-7[/tex]

Step-by-step explanation:

Given

Taylor has nickels and dimes

Number of nickels is 7 less than eight times the number of dimes

If d is the number of dimes, then number of nickels is given by

[tex]\Rightarrow \text{Number of Nickels = }8d-7[/tex]

Answer:

He made 125% of the required minimum.

Step-by-step explanation:

Percentage:

The percentage that a number b is of a is given by:

[tex]P = \frac{100b}{a}[/tex]

In this question:

Minimum of 48, made 60. The percentage 60 is of 48 is:

[tex]P = \frac{100(60)}{(48)} = 100(1.25) = 125[/tex]

He made 125% of the required minimum.

Step-by-step explanation:

Consider we need to find the dimensions and volume of the box.

Given:

The shape of the lamp is a rectangular prism.

It measures 14 high, 9 wide, and 3 long.

There is 1 all around the lamp for bubble wrap

To find:

The dimensions and volume of the box.

Solution:

Length of the box is:

[tex]3+2=5[/tex]

Width of the box is:

[tex]9+2=11[/tex]

Height of the box is:

[tex]14+2=16[/tex]

Therefore, the dimensions of the box are 5 by 11 by 16 units.

The volume of the box is:

[tex]V=l\times w\times h[/tex]

Where, l is length, w is width and h is height.

Putting [tex]l=5, w=11, h=16[/tex], we get

[tex]V=5\times 11\times 16[/tex]

[tex]V=880[/tex]

Therefore, the volume of the box is 880 cubic units.
