the area of the triangle is 24 square feet. what is the length of the base?
A) 8 feet
B) 16 feet
C) 21 feet
D) 36 feet
Answer:
16 feet
Step-by-step explanation:
Area of a Triangle: (Base*Height)/2.
Therefore, Base:(2A)/Height =(2*24)/2=16
Which three lengths could be the lengths
of the sides of a triangle?
A. 4 cm, 8 cm, 13 cm
B. 13 cm, 11 cm, 23 cm
C. 5 cm, 18 cm, 12 cm
D. 25 cm, 8 cm, 16 cm
Given:
The three lengths in the options.
To find:
Which three lengths could be the lengths of the sides of a triangle?
Solution:
If the sum of two smaller sides is greater than the largest side, then the three sides can form a triangle otherwise the triangle is not possible.
In option A, the three sides are 4 cm, 8 cm, 13 cm. Here, the largest side is 13 cm.
Sum of two smaller sides is:
[tex]4+8=12[/tex]
[tex]4+8<13[/tex]
So, the triangle is not possible.
In option B, the three sides are 13 cm, 11 cm, 23 cm. Here, the largest side is 23 cm.
Sum of two smaller sides is:
[tex]13+11=24[/tex]
[tex]13+11>23[/tex]
So, the triangle is possible.
In option C, the three sides are 5 cm, 18 cm, 12 cm. Here, the largest side is 18 cm.
Sum of two smaller sides is:
[tex]5+12=17[/tex]
[tex]5+12<18[/tex]
So, the triangle is not possible.
In option D, the three sides are 25 cm, 8 cm, 16 cm. Here, the largest side is 25 cm.
Sum of two smaller sides is:
[tex]8+16=24[/tex]
[tex]8+16<25[/tex]
So, the triangle is not possible.
Therefore, the correct option is B. The three lengths 13 cm, 11 cm, 23 cm could be the lengths of the sides of a triangle.

The diameter of a circle is 14 ft.
What is the area of the circle in terms of π?
Answer:
49π ft²
Step-by-step explanation:
[tex]A=\pi r^2[/tex] where r is the radius of the circle
To find the radius, divide the diameter by 2:
14 ft ÷ 2 = 7 ft
Plug the radius 7 ft into the equation
[tex]A=\pi (7)^2\\A=49\pi[/tex]
Therefore, the area of the circle in terms of pi is 49π ft².
I hope this helps!
Answer:
49π
Step-by-step explanation:
Diameter=14
Radius=14/2=7
Area=πr squared
Area=7 squared π
Area=49π

Answer:
x = 2 and -4
Step-by-step explanation:
(x + 1)² = 9
First, take the square root of both sides. This will eliminate the square on the left side.
(x + 1) = √9
Note that √9 can be 3 or -3.
Let's write out both possibilities.
(x + 1) = 3
(x + 1) = -3
Solve.
(x + 1) = 3
[subtract 1 from both sides]
x = 2
--
(x + 1) = -3
[subtract 1 from both sides]
x = -4
Your answers are 2 and -4.
Let's check our answers by plugging in the values back into the original equation.
(x + 1)² = 9
(2 + 1)² = 9
(3)² = 9
9 = 9
That solution is correct.
(x + 1)² = 9
(-4 + 1)² = 9
(-3)² = 9
9 = 9
That solution is also correct.
Your answer is correct.
Hope this helps!
Find the range & interquartile range of the data set represented by this box plot.
Answer:
60 and 25
Step-by-step explanation:
The range is the difference between the maximum value and the minimum value.
maximum value = 125, minimum value = 65
range = 125 - 65 = 60
------------------------------------------
The interquartile range is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the value at the right side of the box = 115
Q₁ is the value at the left side of the box = 90
interquartile range = 115 - 90 = 25

Find the perimeter and total area of the composite shape shown below. All measurements are given in inches. Use pi=3.14 in any formulas used.
Answer:
Perimeter of the entire shape is 114.24
Step-by-step explanation:
Use pi x diameter of the semicircle divided by 2 + the diameter to find the perimeter of one semicircle. There are 4 semi circles so you multiply this by 4. Then you take the perimeter of the inside 8x4 = 32. Add them all together to get 114.24

The high temperatures for the last seven days are: High Temperatures: 81, 78, 83, 89, 80, 87, 78
Find the MEAN of the temperatures. Round to the nearest tenths place.
A. 82.3
B. 89
C. 83
D. 78
Answer:
Mean of temperatures = 82.3 (Approx.)
Step-by-step explanation:
Given:
Number of days = 7 days
Temperatures in 7 days = 81, 78, 83, 89, 80, 87, 78
Find;
Mean of temperatures
Computation:
Mean = Sum of all observation / Number of observation
Mean of temperatures = Sum of all seven days temperature / Number of days
Mean of temperatures = [81 + 78 + 83 + 89 + 80 + 87 + 78] / 7
Mean of temperatures = 576 / 7
Mean of temperatures = 82.2857
Mean of temperatures = 82.3 (Approx.)
