If a circle is cut from a square piece of plywood, as shown in the picture below, how much plywood would be leftover?
Answer:
What you need to find is the extra amount of plywood. To do that, you must find the area of the square and the area of the circle and subtract them to find the answer.
Step-by-step explanation:
Formulas:
area of a square: A = bh
area of a circle: A =
square measurements:
b = 28
h = 28
circle measurements:
(≈3.14)
r = 14
A = (28)(28)
A = 784
area of square = 784 in^2
A = 3.14 ()
A = 3.14 (196)
A = 615.44 in^2
784 - 615.44 = 168.56
The amount of plywood left over is 168.56 in^2.
Hope this Helps.

An airplane flies at an altitude of 14,690 feet while a submarine is submerged at a depth of 521 feet below the surface of the ocean. What is the difference between these two elevations?
Answer:
15,211 feet
Step-by-step explanation:
According to the question, given data are as follows:
Airplane altitude = 14,690 feet above
Submarine depth = 521 feet below
So, let the difference between these two elevation be d,
So, we can calculate difference by using following formula:
Difference = Airplane altitude + Submarine depth
By putting the value, we get
Difference = 14,690 + 521
= 15,211 feet

Written as a simplified polynomial in standard form, what is the result when ( x + 2 ) 2 (x+2) 2 is subtracted from 7 x − 4 7x−4?
Answer:
-x²+3x-8
Step-by-step explanation:
Given polynomials are :
f(x) = (x+2)²
p(x) = 7x−4
We need to find a simplified polynomial when f(x) is subtracted from p(x) i.e.
p(x) - f(x) = 7x−4 - (x+2)²
We know that, (a+b)² = a²+b²+2ab
So,
p(x) - f(x) = 7x−4 -(x²+2²+2(x)(2))
= 7x−4 -(x²+4+4x)
= 7x−4-x²-4-4x
= -x²+3x-8
Hence, the result will be -x²+3x-8.

Find the increasing functions. Then arrange the increasing functions in order from least to greatest rate of change. (not all of the functions will be used)
y= 5/2x + 10
y= -1/2x + 1/2
y= 3/2x - 11/2
y= 1/2x - 2
y= 4/3x - 7/3
y=3/4x - 10
Answer:
to a function is increasing we have to find the slope of the function
the higher the slope the faster the growth
Step-by-step explanation:
slope = 5/2. which is 2.5slope 2 = -1/2 which is -0.5slope 3 = 3/2 which is 1.5slope 4 = 1/2 which is 0.5slope 5= 4/3 which is 1.33slope 6 = 3/4 which is 0.75so the function in increasing order
y= -1/2x + 1/2

4. 13x + 5y = -11
13x + 11y = 7
Solution:
Answer:
y=2/3
Step-by-step explanation:
Answer:
(-2,3) x= -2 y=3
Step-by-step explanation:
The first thing you should do is convert both into standard y=mx+b form
For the first equation you subtract 5y and add 11 to both sides to get
13x+11= -5y
you divide by negative 5 to get
-13x/5-11/5=y
For the second equation we subtract 11y and 7 from both sides to get
13x-7= -11y
divide both sides by -11 to get
-13x/11 + 7/11
We then set both equations equal to each other and solve for x
-13x/5-11/5= -13x/11 + 7/11
Add 11/5 to both sides to get
-13x/5 = -13x/11 + 156/55
Add 13x/11 to both sides to get
-78/55x=156/55
Divide and solve for x to get -2
Then plug x = -2 into the original equations to find y
13*-2 + 5y = -11
-26 + 5y = -11
Add 26 to both sides
5y= 15
y =3

Stephanie put $80 in her bank account when she was 5
years old. The bank gave her a simple interest rate of 2.1%.
Does she have enough money to buy a TV for $1,000 after
leaving her money in the bank for ten years?
Answer:
Mynd44
Step-by-step explanation:
Here, we want to check if the amount of money saved is enough to
by a tv
Mathematically, we have the simple interest formula as follows;
I = PRT/100
I = (80 * 2.1*10)/100
I = 1680/1000 = 1.68
Hence, she will not have enough
