I NEED HELP FAST! Two different pools are being considered for a back yard. How many more feet will the larger pool occupy?
Answers
Answer:
138.16ft²
Step-by-step explanation:
Oh boy, this is a long one so hang onto your hats:
We're going to start by finding the area of the smaller circle (or pool) the formula for the area of a circle is pi x radius² and we're given the diameter, here's what we're gonna do:
take the diameter and divide it by 2:
20 ÷ 2 = 10
So now we have the radius and all we have to do is plug that into the formula:
10² = 100
(we're doing 3.14 for pi)
3.14 x 100 = 314
So the area of the smaller circle is 314ft²
Now we gotta do the bigger circle, and since we already have a radius, we can skip a step:
12² = 144
3.14 x 144 = 452.16
So the area of the bigger circle is 425.16ft²
But now we have to find the difference between the two areas:
425.16 - 314 = 138.16
So the larger pool occupies 138.16 more ft² than the smaller pool

1. 45 minutes a day cycling
2.$1.55 on each cup of coffee a day
Step-by-step explanation:
1. You would figure up how much he jogs per week by multiplying 15 times 5 which would be 75 minutes and then from there you would subtract 75 from 300 and get 225 and divide 225 and 5 and end up with 45
2. You would multiply $.75 by 4 to figure up how much he spends on donuts which is $3 and then subtract 15.40 from 3 and get 12.40 and divide 12.40 by 8 since he goes twice a day and end up with 1.55

x=-4/7 and the slope is 7
Answer:
3
Step-by-step explanation:
The slope of a line is the rate of change
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 12 ) and (x₂, y₂ ) = (0, 4) ← 2 ordered pairs from the table
m = [tex]\frac{4-12}{0-2}[/tex] = [tex]\frac{-8}{-2}[/tex] = 4
y = 7x + 4 ← is in slope- intercept form
with slope m = 7
Difference between rates of change = 7 - 4 = 3

ABC is dilated by a factor of 1/2 to produce A'B'C'
Answers
Answer:
B
Step-by-step explanation:
34 x 1/2 = 17 (Line A'B')
28 x 1/2 = 14 (Angle A')
The length of A'B' and measure of angle A after the dilation are respectively: 15 & 28°.
What is the similarity of triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"
By Pythagoras theorem we can check, the given sides do not form a right angle triangle.
Now, let's apply the dilation to the given triangle ABC.
Since the dilation factor is 1/2, the length of each side of A'B'C' will be half of the corresponding side of ABC.
So, the length of AB is 30 and the length of A'B' is 1/2 of AB, which is 15.
To find the measure of angle A', we need to use the fact that corresponding angles in similar triangles are congruent. S
ince ABC and A'B'C' are similar triangles, angle A is corresponding to angle A'. We know that angle A is 28 degrees, so angle A' must also be 28 degrees.
Therefore, the answer is D. A'B' is 15 and mZA' is 28°.

jill has a rectangular table that is 3 1/2 feet long and 1 3/4 feet wide. what is the area of jill’s table?
Answers
Answer:
6 1/8 feet squared
Step-by-step explanation:
The Area of Jill's table is 49/ 8 feet².
What is area?The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.
and, Area of Rectangle = length x width
We have,
Length of rectangular table = 3 1/2 feet = 7/2 feet
Width of rectangular table = 1 3/4 feet = 7/4 feet
So, the Area of rectangular table
= l w
= 7/2 x 7/4
= 49/ 8 feet²
Thus, the Area is 49/ 8 feet².

Write any decimal value with a number greater than 3 in the tenths place
The correct option is (A).
What is Inequality?Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
As per the given data:
We have to fill the blank such that 4.3 < 4.__
To fill the blank:
If the blank is filled with any value having decimal value with a number greater than 3 in the tenths place, the inequality is satisfied.
Let's say x is at the tenth's place
4.3 < 4.x
∴ x > 3
Hence, any decimal value with a number greater than 3 in the tenths place.

The median of the data for Farm Y is greater than the median of the data for Farm X.
Step-by-step explanation:
The median is the middle of the box plot. Median is the middle. If you have to find it on a box plot, look at the box and find the line directly in the middle/the only line IN the box. If it's a list of numbers, you have to put them in order first. Then, find the center number, if it is even, you add the two numbers and divide by two.
Range is when you subtract the largest number by the smallest number.
Third quartile is 75% of the box plot. If you look at the box plot, third quartile is the line that makes up the right side of the box.
First quartile is 25% of the diagram. The first quartile is the left line that makes up the box.
Mode is the number that appears the most often.
Mean is when you add all the numbers together. Then, divide the sum by how many numbers you added.
