The area of the circle that has a radius of 4 feet will be 50.2 square feet.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The radius of the circle is 4 feet. Then the area of the circle is calculated as,
A = π x (4)²
Simplify the equation, then the area of the circle is calculated as,
A = π x (4)²

Josiah kept track of how many songs of each genre were played in an hour from his MP3 player. The counts are displayed in the table below. He has a total of 1,500 songs on his player. Josiah predicted the number of rock songs on his MP3 player to be 300 songs. Which statements about his solution are true? Select three choices. Josiah’s Music Sample 1 Sample 2 R & B 5 R & B 4 Pop 4 Pop 3 Classical 3 Classical 5 Jazz 2 Jazz 4 Rock 6 Rock 4 Josiah’s work: StartFraction 10 over 20 EndFraction = StartFraction x over 1,500 EndFraction. StartFraction 10 times 30 over 20 times 30 EndFraction = StartFraction x over 1,500 EndFraction. 300 = x. He should have found the average of the number of rock songs by averaging 4 and 6 to get 5. He did not multiply the numerator and denominator by the correct number to equal 1,500. His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion. He can only solve the proportion by multiplying the numerator and denominator by a common multiple. He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500
Answer:
Answer is B)
Step-by-step explanation:
Josiah's mistake is (b) He did not multiply the numerator and denominator by the correct number to equal 1,500
The proportion is given as:
Multiply both sides by 1500
Evaluate the expression on the right-hand side
Multiply 10 by 1500 on the left-hand side
Divide 15000 by 20 on the left-hand side
Rewrite the equation as:
From the question, we can see that the products are not well carried out.
Hence, Josiah's mistake is (b)
He got the rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500.
What is Fraction ?What is fraction and example?
A fraction is numerical value that is a part of a whole. It is evaluated by dividing a whole into number of parts
Types of Fractions Proper fraction,Improper fraction,Mixed fraction,Like fractions,Unlike fractions,Equivalent fractions.
The statements that are true about Josiah's solution are:
He correctly found the proportion of rock songs by setting the ratio (number of rock songs in the sample) / (total number of songs in the sample) = (number of rock songs in the MP3 player) / (total number of songs in the sample). sample MP3 player) and solving for x:
Start Fraction 10 over 20 EndFraction = Start Fraction x over 1500 End Fraction.
Initial fraction 10 times 30 over 20 times 30 final fraction = initial fraction x over 1500 final fraction.
300 = x.
He didn't hit the average of the rock songs right because the average of 4 and 6 is 5, not 300.
He did not multiply the numerator and denominator by the correct number to 1500 because he should have multiplied both by 75 instead of 30 to get:
Initial fraction 10 times 75 over 20 times 75 final fraction = initial fraction x over 1500 final fraction. He did not have to divide 10 by 2 when he determined the ratio, because the ratio is already in its simplest form. So the real arguments are:
He got the rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500. He did not have to divide 10 by 2 to determine the ratio.

Triangle ABC has vertices at A(−5, 2), B(1, 3), and C(−3, 0). Determine the coordinates of the vertices for the image if the preimage is translated 4 units right.
A′(−9, 2), B′(−3, 3), C′(−7, 0)
A′(−4, 6), B′(0, 7), C′(−5, 4)
A′(−1, 2), B′(5, 3), C′(1, 0)
A′(−5, −2), B′(1, −1), C′(−3, −4)
Answer:
A′(−1, 2), B′(5, 3), C′(1, 0)
Step-by-step explanation:
When translating a pre-image, there are some easy tricks you can use to figure out what the coordinates of the image are instead of drawing it out.
When translated to the right, add the number of units translated to the x-value.
This is because, when we move right on a coordinate plane, we move along the x-axis toward the positive numbers.
When translated to the left, subtract the number of units translated to the x-value.
This is because, when we move left on the coordinate plane, we move along the x-axis toward the negative numbers.
When translated up, add the number of units translated to the y-value.
This is because when we move up on the coordinate plane, we move along the y-axis toward the positive numbers.
When translated down, subtract the number of units translated to the y-value.
This is because when we move down on the coordinate plane, we move along the y-axis toward the negative numbers.
This is how I solved this problem. Apply these tricks and you will see that you will get the correct answer.

Answer: 76.5
Step-by-step explanation: First of all, you should divide all of the shapes into 1 shape. That leaves you with 3 separate shapes to find the area to. First, let's start at the bottom rectangle. The area of that rectangle is 42. Now, lets to the middle rectangle. 4x7=28, which is the area of that rectangle. Now, we do the triangle. We have to find out the side length, but we know that the bottom length is 13. So, we add 6+7 to get that specific length (13). Because this shape is a triangle, we divide 13 by 2 (6.5). Finally, we add 42+28+6.5, and we get 76.5. Hope this helped!

HELP THIS DUE TOOODAAAY!!!
Answer:
163/40
Step-by-step explanation:
multiply 4x40
then add 3
= 163
then put it over 40
163/40
Answer:
To simplify 4 3/40, we need to convert the mixed number to an improper fraction and then simplify:
4 3/40 = (4 × 40 + 3) / 40 (convert to improper fraction)
= 163 / 40
Now, we can simplify this fraction by finding the greatest common factor (GCF) of the numerator and denominator, which is 1:
163 / 40 = (163 ÷ 1) / (40 ÷ 1)
= 163 / 40
Therefore, 4 3/40 in simplest form is 163/40.

2. The figure below consists of a triangle, a rectangle, and a trapezoid. What is the area of the figure in square units?
Answer: 56
Step-by-step explanation
well you could break up this "shape"into multiple different parts (already broken) you want to find the area of all the shapes then add the areas.
first lets start off with the two triangles at the top the area for a triangle is base x height divided by 2, the base would be because of the 5 and the 2 at the edge of the triangle and the height would be 4 because of the 10 at the top minus the 6
for this case we wouldn't divide by 2 because there are 2 triangles, so there is no point. ( 7 X 4 = 28)
then we would move onto the large rectangle, the area of a triangle is base x height, base=4 height=5 (4 x 5 = 20)
then we move onto the smaller rectangle using the same area formula, base=2 because if you look at the 6 on the top and minus the 4 of the large rectangle. height =3 (2x3=6)
and the last one the small triangle, for this we would use the same formula ( base x height divided by 2) we are dividing by two because there is only 1 triangle. base=2 and height=2 because of the five on the right minus the 3 *height of the smaller rectangle* so
(2X2 divided by 2= 2)
then we add them all up, 28 + 20 + 2 + 6 = 56

Explanation: 1/5 divided by 4 in fraction form is 1/20, and in decimal form it is 0.05.
Can someone help! Thank you!
Reason:
The numerator is [tex](2.1)^5[/tex]
Raising that to the third power gives
[tex]((2.1)^5)^3 = (2.1)^{5*3} = (2.1)^{15}[/tex]
We multiply the exponents. The general rule is

Therefore,

What are the types of translations?There are three types of translations -
reflection
rotation
dilation
Given is that a Polygon JKLM is drawn with vertices J(−4, −4), K(−4, −6), L(−1, −6), M(−1, −4). We have to find the image coordinates of M′ if the preimage is reflected across y = −3.
The reflection of point (x, y) reflected across the line y = a is (x, 2a - y)
So, we can write the coordinates of point M' if the preimage is reflected
across y = −3 would be -
M(-1, -4) → M'(-1, 2 x - 3 + 4)
M(-1, -4) → M'(-1, -2)
Therefore, the coordinates of point M' if the preimage is reflected
across y = −3 would be M'(-1, -2).
