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.
A car travelled at 50 km/hr for 3 hours How far did the car travel?
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!

Sarah wanted to know how many of her fellow students have at least one cat at home. She randomly sampled 30 students from her school and 11 of them answered yes. What is the approximate proportion of students who have at least one cat?
A
0.11
B
0.27
C
0.33
D
0.37
The proportion of students who have at least one cat is 0.37
The correct option is : (D)
What is fraction?A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Total students samples=30
Students answered yes =11
The proportion of students who have at least one cat
= [tex]\frac{11}{30}[/tex]
= 0.367
≈ 0.37
Hence the proportion of students who have at least one cat is 0.37.

You estimate that your new business's revenue will grow at a compounded rate of 30% each month for the first 6 months. If your third month's revenue is estimated at $5,000, what is your second month's revenue? (Round to the nearest dollar.)
a) $2,945
b) $3,846
c) $4,012
d) $4,333
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

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

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

Rosa is picking out fabric for her bedroom. She has 6 fabric samples, and 2 of them are floral. What is the probability that a randomly selected fabric sample will be floral? Write your answer as a fraction or whole number.
Answer:
Probability of selected sample is floral = 1 / 3
Step-by-step explanation:
Given:
Number of fabric sample = 6 sample
Number of floral sample from all samples = 2 samples
Find:
Probability of selected sample is floral
Computation:
Probability of a sample = Favorable outcome / Total outcomes
Probability of selected sample is floral = Number of floral sample / Number of fabric sample
Probability of selected sample is floral = 2 / 6
Probability of selected sample is floral = 1 / 3
Find the area of the shaded region
Answer:
40
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

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]

Two recreational basketball teams, Eagleton and Hawkville, wanted to compare the heights of their players in inches.
The heights of Eagleton's basketball players are 70, 71, 72, 74, 74, 75, and 75. The mean height of the Eagleton players is 73 inches
The 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.
Which statement is true?
Team Hawkvilles's players heights vary the same amount as Team Eagleton's players heights.
The range of Eagleton's players heights is greater than the range of Hawkville's players heights.
Team Hawkville's players heights vary more than Team Eagleton's players heights.
Team Eagleton's players heights vary more than the heights of Hawkville's players.
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.
