What is the area of this composite figure?
12.56 in. sq
10.28 in. sq
7.14 in. sq
16.56 in. sq
Answers
Answer:
7.14 in. sq
Step-by-step explanation:
First find the area of the square; 2x2=4
Now find the area of the semi-circle; radius = 1.
1 squared= 1 Now multiply by 3.14 which equals 3.14
Now divide by 2 because it's a semi-circle, you get 1.57.
Multiply 1.57 by 2 because you have 2 semi-circles, the would equal 3.14
Add 4+3.14 and you get 7.14
The area of the composite figure is 7.14 in. sq

i have four numbers that are 5, 6, 8, 10 which three of these numbers form a right triangle
Answers
Answer:
6, 8, 10
Step-by-step explanation:
Pythagorean theorem:
To form a right triangle we need to have 3 numbers where when we take the sum of the squares of the first two it equals the square of the third number.
If we take 6, 8, and 10 then if makes this true.
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100 (This means it's correct)

Simple Interest Formula:
[tex]A = P(1+rt)\\[/tex]
A = 37375 in this case. This is the amount of money you'll have after 9 years. However, the question asks for how much interest you'll gain, meaning you have to subtract the principle from it. 37375 - 25000 = 12375
in circle F, points A,B,C,D, and E are located on the circle such that measure of C=119°, and BE is perpendicular AD. determine the measure of arc AE. show how you arrived at your answer.
Answers
Answer:
Measure of arc AE = 58°
Step-by-step explanation:
As shown: ABCD is a quadrilateral, ∠C = 119°
So, ∠C + ∠A = 180°
∴ ∠A = 180° - ∠C = 180° - 119° = 61°
ΔAGB is a right triangle at G
So, ∠A + ∠B = 90°
∴ ∠ABG = 90 - ∠A = 90 - 61 = 29°
Arc AE opposite to the angle ∠ABG
So, measure of arc AE = 2∠ABG = 2 * 29° = 58°

y = b lines have a slope of 0Parallel Lines - Lines that have the same slope but different y-intercepts. They never intersect.Step-by-step explanation:
We are given the line y = 6, a horizontal line with a slope of 0.
According to the answer choices, we need to find an equation of a line that also has a slope of 0.
A, B, and D are all incorrect, as they have a different slopes than the original line (Slope of -6, undefined, and 6 respectively).
Therefore, our only option is C, which is the correct answer.
y = 1 has the same slope, a slope of 0. However, it has a different y-intercept, a y-intercept of 1 compared to the original y-intercept 6. They are parallel and will never intersect.

1. The monthly rents for studio apartments in a certain city have a mean of $920 and a standard deviation of $190. Random samples of size 25 are drawn from the population and the mean of each sample is determined.
What is the mean of the indicated sampling distribution of sample means?
2. What is the standard error of the indicated sampling distribution of sample means?
3. Which one is more likely to take place?
a. Find one studio apartment that has a rent between $901 and $939.
b .Find a sample of 25 studio apartments with a mean rent between $901 and $939.
Answers
Answer:
1)Mean=920 $
2)Standard Error =S.E.=38
3)more likely to take place Event 25 studio apartments with a mean rent between $901 and $939
Step-by-step explanation:
Given:
True mean =920 $
S.D=190 $
No .of samples=25
To Find:
1)Mean of sample.
2)S.E
Solution:
Now , the mean for given sample distribution is given as 920 $
Hence Mean =920 $
Now calculating the Standard error
S.E.= S.D./Sqrt(n)
=190/Sqrt(25)
=190/5
=38
Therefore the Standard error is about 38 .
a) When n=1 then P(901≤X≤939)
So,
Z1=(901 -920)/190/Sqrt(1)]
Z1=-0.1
Z2=(939-920)/(190/Sqrt(1)]
Z2=0.1
So
Pr(-0.1≤Z≤0.1)=P(Z≤0.1)-P(Z≤-0.1)
=0.5398-0.4602
=0.0797 % chance of the sample distribution
b)n=25 then P(901≤X≤939)
Z1=(901-920)/S.E
Z1=-19/38=
Z1=-0.5
And Z2=0.5
So,
Pr(-0.5≤Z≤0.5)
=Pr(Z≤0.5)-Pr(Z≤-0.5)
=0.6915-0.3085
=0.3829
i.e 38.29 % chance of the sample distribution
Hence More likely to take place will be a sample of 25 studio apartments with a mean rent between $901 and $939.
0.3829>0.0797.
Because the probability of causing above event is more than the option A.

Assume the Pentagon is a regular pentagon with side length 300. The perimeter of the Pentagon is
Answers
Answer:
1500 units.
Step-by-step explanation:
-A pentagon is a a regular pentagon with 5 equal sides.
-Since the side length's are equal, the perimeter is simply the product of one side length by the number of sides of the polygon.
-Given its sides measures 300 each, its perimeter can be calculated as:
[tex]P=5s\\\\=5\times 300\\\\=1500 \ units[/tex]
Hence, the Pentagon's permimeter is 1500 units.

Answers
Answer:
1/3
Step-by-step explanation:
The fraction of the circumference that the arc subtends is 1/3.
Explanation:An arc that subtends a central angle measuring 2π/3 radians is a fraction of the circumference. To find the fraction, we can use the formula:
Fraction of circumference = (angle/2π) x 1
Substituting the given angle into the formula, we have:
Fraction of circumference = (2π/3 /2π) x 1

What is the area of the following circle? Either enter an exact answer in terms of pie or use 3.14 for pie and enter your answer a decimal
Answers
The area of a circle with a radius of 1.2 meters is 4.5 m², rounded to two significant figures to match the precision of the given radius.
Explanation:The area of a circle is given by the formula A = πr², where π (pi) represents a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. When calculating the area with a radius of 1.2 meters, we get the precise calculation as A = π(1.2 m)² = 4.5238934 m². However, as the radius is given with only two significant figures, the area should also be rounded to two significant figures, resulting in A=4.5 m².

There is 1000cm3 of aluminum available to cast a trophy that will be in the shape of a right square pyramid. Is this enough aluminum for a trophy that has a base edge of 10 cm and a slant height of 13 cm.
Answers
The 1000 cubic centimeters of aluminium is enough for aluminium a trophy that will be in the shape of a right square pyramid and has a base edge of 10 cm and a slant height of 13 cm.
Step-by-step explanation:
The given is,
Volume of aluminium available is 1000 cubic centimeters
Shape of trophy is right square pyramid
Trophy has a base edge of 10 cm and slant height of 13 cm
Step:1
Formula for volume of right square pyramid,
[tex]Volume, V = a^{2}\frac{h}{3}[/tex].....................................(1)
Where, a - Base edge value
h - Height of pyramid
From given,
a = 10 cm
h = 13 cm
Equation (1) becomes,
[tex]= 10^{2}(\frac{13}{3} )[/tex]
[tex]= (100)(4.333)[/tex]
[tex]= 433.33 cm^{3}[/tex]
Volume of trophy = 433.33 cubic centimeters
Compare with the volume of available aluminium and volume of right square pyramid,
[tex]Volume of available aluminium > Volume of right square pyramid[/tex]
[tex]1000 cm^{3} > 433.33 cm^{3}[/tex]
So, the given volume of aluminium is enough to make right square pyramid shaped trophy.
