Find the Area of the figure below, composed of a rectangle and two semicircles. Round to the nearest tenths place.
Answers
The area of the figure composed of a rectangle two semi circle is approximately 100.3 sqaure units
What is the area of the composite figure?The figure in the image compose of a rectangle and two semi circle.
The area of rectangle is expressed as:
Area = length × width
The area of a semi circle = half are of circle = 1/2 × πr²
Where r is the radius.
From the image:
Length = 12 units
Width = 6 units
Diameter = 6 units
Radius r = diameter/2 = 6/2 = 3 units
Now, area of the figure will be:
Area of figure = ( Area of rectangle ) + 2( Area of semi circle )
Hence:
Area of figure = ( 12 × 6 ) + 2( 1/2 × π × 3² )
Area of figure = 72 + 28.3
Area of figure = 100.3 sqaure units
Therefore, the area of the figure is 100.3 sqaure units.

22 foot ladder is placed against a vertical wall of building with the bottom of the ladder standing on level ground 9 feet from the base of the building how high up the wall does the ladder reach
Answers
Answer:
20.1 feet
Step-by-step explanation:
We solve the above question using the Pythagoras Theorem
The Pythagoras Theorem =
Opposite² + Adjacent ² = Hypotenuse²
From the above question,
Opposite side = Height of the wall = x
Adjacent side = Distance from the base of the building = 9 feet
Hypotenuse = Length of the ladder = 22 feet
Hence:
x² + 9² = 22²
x² = 22² - 9²
x = √22² - 9²
x = √403
x = 20.0748599 feet
Approximately = 20.1 feet
Therefore, the height of the wall = 20.1 feet

This circle graph shows how Jimmy spent his time during the last 24 hours.
How much more time did he spending watching T.V. and Talking on the Phone than he did Going to School?
8 hours
5 hours
1.92 hours
1.2 hours
Answers
Answer:
Excess time = 1.2 hour
Step-by-step explanation:
Given:
Total time = 24 hours
Talking on phone = 17 %
Sleeping = 33%
Going to school = 25%
Studying = 4%
Eating = 8%
Computation:
Watching TV percent = 100% - Talking on phone - Sleeping - Going to school - Studying - Studying - Eating
Watching TV percent = 100% - 17% - 33% - 25% - 4% - 8%
Watching TV percent = 13%
Time taken by school = 24 x 25%
Time taken by school = 6 hour
Time taken by watching T.V. and Talking on the Phone = 24 x (13% + 17%)
Time taken by watching T.V. and Talking on the Phone = 7.2 hour
Excess time = 7.2 - 6
Excess time = 1.2 hour

Answer:
The least common multiple of 8 and 12 is 24
Explanation:
Find and list the multiples each number until the first common multiple is found.
This is the lowest common multiple .
Multiples of 8
8, 16, 24, 32,40
Multiples of 12
12,24, 36,48
Therefore,
LCM of 8 and 12 is 24
Answer: The answer is 24
Step-by-step explanation: One easy way to find least common multiples is to take the large number and multiply it by increasing numbers (1,2,3,etc.) until a number is found that is also divisible by the smaller number.
In this case, we can multiple 12 by increasing numbers until we find a number that is also divisible by 8.

Answer:

Step-by-step explanation:
The intercepts can be found by setting one variable to zero and solving for the other.
y-intercept: 30·0 +15y = 90 ⇒ y = 90/15 = 6, point (0, 6)
x-intercept: 30x +15·0 = 90 ⇒ x = 90/30 = 3, point (3, 0)
The graph is easily made by plotting the intercepts and drawing a line through them.

find the area of the figure.
Answers
Answer:
Step-by-step explanation:
Split the figure into 2. You didn't provide the measurements, so if you have them, just take it the rhombus and make it into a rectangle and find the area of that. find the area of the rectangle. add the two values together. Based off of the image, I'd say that the rhombus would be 15 units and the rectangle would also be 15 units so the answer would be 30 units
Answer:
30
Step-by-step explanation:
area of a rectangle is width times length so 3 squares times 5 squares gives that part an area of 15 squares squared ooh tahts a fun word to say
umm and then area of a trapezoid is a+b/2 times h
so a and b are the top and bottom sides of the trapezoid so 5 squares on top and 5 squares on bottom so that equals 10 divided by 2 is 5 then times the height would be 3 so 5 times 3 equals 15
so 15 the area of the trapezoid plus the area of the rectangle 15 equals a total area of 30 squares squared
