Answer:

- 81, 8.54, 8 13/29, 8.6

Step-by-step explanation:

A slightly more accurate value is 38.28 cm^2, when using pi = 3.14

=================================================

Explanation:

The vertical height of the rectangle is 4 cm, which forms the diameter of the semicircle. The diameter cuts in half to 4/2 = 2, which is the radius.

The area of a full circle with radius r = 2 cm is approximately pi*r^2 = 3.14*2^2 = 12.56 square cm.

Cut that in half to get (12.56)/2 = 6.28 square cm. This is the approximate area of the semicircle.

--------

The area of the rectangle is length*width = 6*4 = 24 square cm.

The triangle has its bottom portion of 4 cm (because 10-6 = 4) and its height is 4 cm, so we get the triangle area of base*height/2 = 4*4/2 = 8 square cm.

The last thing we do is add up all the results we got:

6.28 + 24 + 8 = 38.28

That rounds to 38 square cm when rounding to the nearest whole number.

Answer:

Area=120

Step-by-step explanation:

[tex]Area=\frac{base1+base2}{2} *height[/tex]

[tex]Area=\frac{8+12}{2} *12[/tex]

[tex]Area=10*12[/tex]

[tex]Area=120[/tex]

Answer:

25km

Step-by-step explanation:

50 km = x km

1 hr        3 hrs

From there, you cross-multiply and solve for x.

(50 km)*(3 hrs) = (x km)*(1 hr)

x km = (50)*(3)/(1) = 150km

Now, your other question can be answered the exact same way. 30 minutes is the same as 1/2 of an hour, so just put 0.5hrs in where the 3hrs was in the previous problem. So to show you how it works once more, here are your calculations:

50 km = x km

1 hr        0.5 hrs

(50 km)*(0.5 hrs) = (x km)*(1 hr)

x km = (50)*(0.5)/(1) = 25km

I hope that helps!

Answer:

b

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

let a = second month's revenue

5000 = a(1.3)

a = 5000 / 1.3 = 3846

Answer:

Option C

Step-by-step explanation:

Given -

Height of the Eagleton's basketball players are 70, 71, 72, 74, 74, 75, and 75.

The mean height of Eagleton's basketball players is 73 inches

Heights of Hawkville's basketball players are 70, 70, 71, 72, 72, 72, and 77. The mean height of the Hawkville players is 72 inches

The range of any given data set is the difference in the maximum and minimum value the frequencies with in the data set.

The range of Hawkville's basketball players is 77-70 = 7

The range of Eagleton's basketball players is 75-70 = 5

Hence, the height of Hawkville's basketball players vary more as compared to the height of players of Eagleton.

Option C is correct

Answer:1/2

Step-by-step explanation:it’s a 50/50 chance

Given:

length of rectangle = 4 units

Height of rectangle = 2x + 6 units

To find:

Not given, so I will find area and perimeter of rectangle. If you want the length of the diagonal of the rectangle, please ask me.

Steps:

Perimeter of rectangle = 2(L + B)

                                      = 2( 4 + 2x + 6 )

                                      = 2( 10 + 2x )

                                      = 2 * 10 + 2 * 2x

                                      = 20 + 4x units

Area of rectangle = L * B

                             = 4 * (2x + 6)

                             = 4 * 2x + 4 * 6

                             = 8x + 24 units²

Therefore, the perimeter of the rectangle is 20 + 4x units, and the area of the rectangle is 8x + 24 units².

Happy to help :)

If you need any help, feel free to ask.

Answer:

we multiply 4 by 2x + 6

4(2x + 6) = 8x + 24

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, a complete question is attached.

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled, obtuse, acute, scalene, isosceles, equilateral triangle.

Trigonometric identities are used to show the relationship between the sides and the angles in a right angled triangle. Below are some trigonometric identities:

sin(θ) = opposite / hypotenuse; cos(θ) = adjacent / hypotenuse; tan(θ) = opposite / adjacent

The hypotenuse is the longest side in the triangle.

From the image attached:

sin(α) = opposite side / hypotenuse side

sin(α) = 7 / 25

Answer:

Step-by-step explanation:

area of shaded region = area of whole figure - area of non shaded region

area of whole figure: The whole figure is a rectangle

The area of a rectangle can simply be calculated by multiplying the width by the length

The given width is 10ft and the given length is 8ft

Hence area of whole figure = 10 * 8 = 80ft²

Area of non shaded region: the non shaded region also creates a rectangle

Like stated previously the area of a rectangle can simply be calculated by multiplying the width by the length

The given width is 5ft and the given length is 8ft

Hence, area of non shaded region = 5 * 8 = 40ft²

Finally we can find the area of the shaded region.

We can easily do this my subtracting the area of the nonshaded region from the area of the whole figure

If we have identified that the area of the whole figure is 80 and the area of the non shaded region is 40

Then, area of shaded region = 80 - 40 = 40ft²

The distance between the boat and the hiker

To do this, we make of sine rule.

[tex]\frac{a}{\sin A} = \frac{b}{\sin B} =\frac{c}{\sin C}[/tex]

In this case:

[tex]x = ??[/tex]

[tex]X = 68[/tex]

[tex]a = 66[/tex]

[tex]A = 35[/tex]

So, we have:

[tex]\frac{x}{\sin 68} = \frac{66}{\sin 35}[/tex]

Make x the subject

[tex]x = \frac{66}{\sin 35} * \sin 68[/tex]

Using a calculator, we have:

[tex]x = \frac{66}{0.5736} * 0.9272[/tex]

[tex]x = 115.063* 0.9272[/tex]

[tex]x = 106.68[/tex]

[tex]x \approx 107[/tex]
