Help me plsssssssssssssss
Answer:
Correct: A, B, C, E, AND F
Step-by-step explanation:
The reason being, that the larger the negative number, the smaller it gets. Think of it like this:
One person owes another, 8 dollars, and let's say he currently has none. So if he owes 8 dollars and he has none, then it would be 0-8, or, -8.
Now let's say someone else owes 200 dollars, and they have 100 dollars.
If they give 100 dollars, they still need to give another 100, right? so it would be -100 dollars, therefore, a greater debt than the guy with the 8 dollars.
If a negative number looks larger than another, in reality, it's just a bigger debt to pay, so it's smaller worth. -8 is larger than -100 because it's closer to 0.
Last example:
-100, -75, -50, -30, -23, -8, -2, 0, 1, 2, 3... See? -8 is closer to zero than -100, so it's larger.
C is correct because negatives are smaller than positives. -1 is below 0, so it's smaller than 1, which is greater than 0.
Hope this helps :)
can someone pls help me i’m stressed out over this. all you have to do is find the area of the shaded part, thank you sm <3
Answer:
88.86
Step-by-step explanation:
Okay, first find the area of the circle (πr^2)
The diameter of the circle is 14, however we need the radius. Simply divide the diameter by two.
[tex]\pi 7^{2}[/tex]
3.14*49 =153.86
Next, we find the area of the rectangle (bh)
13*5 =65
Subtract the rectangle from the circle.
153.86-65 =88.86
Hope this helps you :)

Answer:
11.06
Step-by-step explanation:
part 2. Algebraically find the inverse of the function
1. f(x) = -3(x - 4)^2 - 6
2. y = sqrt (x - 4)^2 + 3
3. y = 4 cube root (x)
Answer:
1. f⁻¹(x) = ±²√(-⅓(x + 6)) + 4
2. y = ²√(x–3) + 4
3. y = (x/4)³
9514 1404 393
Answer:
f⁻¹(x) = 4 ±(1/3)√(-3x-18)y = (x -3)² +4y = x³/64Step-by-step explanation:
To find the inverse function, solve for y the equation ...
x = f(y)
__
1.
[tex]x=f(y)\\\\x=-3(y-4)^2-6\\\\x+6=-3(y-4)^2\qquad\text{add 6}\\\\\pm\sqrt{\dfrac{x+6}{-3}}=y-4\qquad\text{divide by -3, square root}\\\\4\pm\dfrac{1}{3}\sqrt{-3(x+6)}=y\qquad\text{add 4, rationalize the denominator}\\\\\boxed{f^{-1}(x)=4\pm\dfrac{1}{3}\sqrt{-3x-18}}\qquad\text{simplify the radical}[/tex]
__
2.
[tex]x=\sqrt{y-4}+3\\\\x-3=\sqrt{y-4}\qquad\text{subtract 3}\\\\(x-3)^2=y-4\qquad\text{square both sides}\\\\\boxed{y=(x-3)^2+4}\qquad\text{add 4}[/tex]
__
3.
[tex]\displaystyle x=4\sqrt[3]{y}\\\\\frac{x}{4}=\sqrt[3]{y}\\\\\left(\dfrac{x}{4}\right)^3=y\qquad\text{cube both sides}\\\\\boxed{y=\dfrac{x^3}{64}}[/tex]

The base of a rectangular prism has a length of 36 centimeters and a width of 29 centimeters. If the volume of the rectangular prism is 7,830 cubic centimeters, how long is the HEIGHT of the prism?
Answer:
7.5
Step-by-step explanation:
you think about the way you would normally solve it but a bit backwards therefore multiply 36x29 and that equals 1,044 and divide that from 7,830 and thats 7.5 multiply to check
65 and 40%how many left
Answer:
16
Step-by-step explanation:
Divide 65 by 40 and then multiply it by 10. That gets you 16.25 so you have to round it because you can't have 1/4 of a person. So you'll get 16.

Answer: 15.45133224
Step-by-step explanation:
Find the area of the half circle.
r=6
pi (6)^2/2
Divide by two because it is a half circle not a circle.
pi (6)^2/2=18 Pi
We know there are two square with even side lengths so we know the sides of the two squares are 6 it is the same as the radius of the circle.
We multiply B*H= Area of the square
6*6=36 is the length of half of the rectangle aka the square
So we multiply that by 2 because there are 2 squares so we get 72
72-18 Pi= 15.45133224
Answer:
15.48 is the answer
Step-by-step explanation:

72-56.52= 15.48

Answer:
[tex]A=24[/tex]
Step-by-step explanation:
For finding the area of a trapezoid you first have to use the correct formula which is [tex]A=\frac{1}{2}(b_1+b_2)h[/tex].
Now we plug in what we already know.
[tex]A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(5+7)(4)[/tex]
Now we start with the parenthesis
[tex]A=\frac{1}{2}(12)(4)[/tex]
Now if you can, you can multiply the 1/2 and the 12 and the 4 using a calculator or mentally
[tex]A=24[/tex]

Lisa has $7.80 to spend on some tomatoes and a loaf of bread. Tomatoes
cost $1.20 per pound, and a loaf of bread costs $1.80.
The inequality 1.20x + 1.80 s 7.80 models this situation, where x is the
number of pounds of tomatoes.
Solve the inequality. How many pounds of tomatoes can Lisa buy?
Answer:
Lisa can buy 5 pounds of tomatoes.
Step-by-step explanation:
Given that Lisa has $ 7.80 to spend on some tomatoes and a loaf of bread, and tomatoes cost $ 1.20 per pound, and a loaf of bread costs $ 1.80, to determine how many pounds of tomatoes she can buy, the following calculation must be performed:
1.20X + 1.80 = 7.80
1.20X = 7.80 - 1.80
X = 6 / 1.20
X = 5
So Lisa can buy 5 pounds of tomatoes.
