Answer:
jeez, one lazy person must you be if you dont have time to finish this xD
answer is 181
Step-by-step explanation:
well first divide the two objects, a triangle, and a rectangle. Now we have no idea what the bottom of the triangle is so lets calculate that. 18 - 2 -5 = 11
so the triangles dimesions are a10, b11. Now we have to implement the pythagorem theroem since it doesnt give us the side "c". its a simple a^2+b^2=c^2. so side "c" is 14.866. now we can calculate and add everything together. so 18*7=126. and the triangles area is 55. so add 126+55 and viola. you get 181. Im a bit skeptical that i got something wrong but i hope its all correct. hope this helps!

A spinner is divided into equal sections, each labeled with a number between 1 and 5? Over the course of 150 spins, what is the best estimate of how many times you would expect that the hand of the spinner will stop on a 3? Need it kinda fast but take your time.
Answer:
30 times
Step-by-step explanation:
The computation of the number of times that expected to stop on 3 is as follows:
Since there are 150 spins
And, each labeled with a number that lies between 1 and 5
So the number of times should be
= 150 ÷ 5
= 30 times
Hence, the number of times would be 30

Explain how to simplify the rational expression x2 - 2x -89x2 - 16x2 - 163x2 + 10 x + 8. (be sure to include the simplified rational expression)
Answer:
267x2 -8x -8 where
x=- 4± 2√ 538/267
Step-by-step explanation:
x2 - 2x -89x2 - 16x2 - 163x2 + 10 x + 8
= x2 -89x2 - 16x2 - 163x2 - 2x+ 10 x + 8
= -267x2+8x +8
= 267x2 -8x -8
First the like terms are arranged and then added . All the co efficients of x2 are added and x are added separately.
Using the quadratic equation to find the value of x
a= 267 , b= -8 and c= -8
x= -b±√b²- 4ac/ 2a
x= -8±√64 +8544/534
x= -8±√8608/534
x=-8±√ 2 x 2 x 2 x 2 x 2 x 269/534
x=-8± 4√ 2 x 269/534
x=- 4± 2√ 2 x 269/267
x=- 4± 2√ 538/267

WOULD YOU RATHER receive 40% off 15 copies OR 50% of 25 copies?
justify your reasoning with mathematics.
Answer:
hahaha
Step-by-step explanation:
hahahahahayou dont know d answer hahaha but i know its a secret
Answer:
If 40 percent off 15copies and each copies 100 pounds then it would cost 60 pound per copy times it by 15 = 900 pounds
whereas 50 percent off 25 copies = 50 pounds times 25=1250 so therefore you want 40 percent off 15 copies

Cheese sticks that were previously priced at "10 for $1" are now "4 for $1". Find each percent change
Answer:
The price per cheese stick was increased by 150%.
The amount of cheese sticks per $1.00 has decreased by 60%.
Step-by-step explanation:
The price per cheese stick was $0.10
1.00 (dollar) divided into 10 (cheese sticks) gives you 0.1, which means each cheese stick costs $0.10The current price per cheese stick is $0.25
1.00 (dollar) divided into 4 (cheese sticks) gives you 0.25, which means each cheese stick costs $0.25That means the price per cheese stick was raised by 150%.
That also means the amount of cheese sticks you could buy for $1.00 has decreased by 60%.

ed made a large cube by gluing together a number of identical small cubes together
Answer:
thats cool not realy a question tho can I have brainlest
Step-by-step explanation:
Ed painted 95 faces of a large cube.
What is the Cubic equation?Cubic equations are polynomials of degree 3. That means the maximum degree of the polynomial is three.
And the standard form of the cubic equation is;
f(x) = ax³ + bx² +cx +d, where a, b, c, and d are constant coefficients a ≠ 0.
Let's assume that the original cube that Ed made had n small cubes along each edge.
Then the total number of small cubes in the large cube is n³.
Let p be the number of faces that Ed painted.
Each small cube has 6 faces, and if a face is painted, it will not be visible after the large cube is assembled.
So the total number of unpainted faces is 6n³ - p.
When Nicole drops the cube, each small cube will be separated from the others, and all painted faces will become visible.
So the total number of painted faces is equal to p minus the number of small cubes that don't have any painted faces, which is 45.
Therefore, we have a cubic equation:
p - 45 = 6n³ - p.
Simplifying this equation, we get:
2p =6n³ + 45
p = 3n³ + 22.5
We know that p is an integer, so 3n³ + 22.5 must be an integer.
This means that n³ must be a multiple of 2/3.
The smallest integer value of n that satisfies this condition is n = 3.
So Ed made a cube with 3 small cubes along each edge, and he painted:
the value of the cubic equation at 27,
p = 3n³ + 22.5 = 3(27) + 22.5 = 94.5 ≈ 95 faces of the large cube.
Therefore, 95 faces of the large cube.

The complete question:
Ed made a large cube by gluing together a number of small identical cubes and then he painted some of the faces of the large cube. His sister Nicole dropped the cube and it broke into the original small cubes. 45 of these small cubes didn't have any painted faces. How many faces of the large cube did Ed paint?

Chloe was given a large box of 36 chocolates for her birthday. If she eats exactly 2 chocolates each day, how many chocolates would Chloe have remaining 8 days after her birthday?
Answer:
20 chocolates
Step-by-step explanation:
I got 20 chocolates as my answer because I multiplied the 2 chocolates eaten each day by the 8 days. She eats 2 chocolates each day for 8 days. 8x2=16. Then, I took the 36 chocolates and subtracted 16 chocolates eaten to get the answer of how many chocolates are left. 36-16=20. Therefore, Chloe has 20 chocolates.
Chloe has 20 chocolates remaining 8 days after her birthday.

A (5, 3), B (2, 1), and C (-2, 4) are the coordinates of a triangle's vertices. If the triangle is reflected over the x-axis, what are the coordinates of the image?
1. A'(5, -3), B'(2, -1), C'(-2, -4)
2. A'(-5, 3), B'(-2, 1), C'(-2, 4)
3. A'(-5, 3), B'(-2, 1), C'(2, 4)
4. A'(-5, -3), B'(-2, -1), C'(2, -4)
Answer:
1 is the answer
Step-by-step explanation:
When coordinates are reflected over the x axis, the x coordinates stay the same but the y coordinates becomes either negative, if they were positive, or positive, if they had orginally been negative.

A package of screen protectors for an iPhone
are priced $12.99. What is the price of the screen
protectors after 6% sales tax?
Answer: $13.77
Step-by-step explanation:
To get the final price for the screen protectors, we have to calculate the value of the tax and add to the current price of the screen protector.
The sales tax will be:
= 6% × $12.99
= 6/100 × $12.99
= 0.06 × $12.99
= $0.7794
The price of the screen protector will now be:
= $12.99 + $0.7794
= $13.7694
= $13.77
