The sum of 8 and t ⇒ 8 + t

Answer:

(a)

[tex]\%Decrease= 12.5\%[/tex] --- TV

[tex]\%Decrease= 20\%[/tex] --- Laptop

(b) Laptop

Step-by-step explanation:

Given

Normal                       Sales

[tex]TV = 2000[/tex]                  [tex]TV = 1750[/tex]

[tex]Laptop = 1800[/tex]             [tex]Laptop = 1440[/tex]

Solving (a): Percentage increase of decrease for both

Percentage change is calculated as:

[tex]\%Change = \frac{New - Old}{Old} * 100\%[/tex]

For TV

[tex]\%Change = \frac{1750 - 2000}{2000} * 100\%[/tex]

[tex]\%Change = \frac{-250}{2000} * 100\%[/tex]

[tex]\%Change = -0.125* 100\%[/tex]

[tex]\%Change = -12.5\%[/tex]

It is a decrease because it is negative

[tex]\%Decrease= 12.5\%[/tex]

For Laptop

[tex]\%Change = \frac{1440 - 1800}{1800} * 100\%[/tex]

[tex]\%Change = \frac{-360}{1800} * 100\%[/tex]

[tex]\%Change = -0.2* 100\%[/tex]

[tex]\%Change = -20\%[/tex]

It is a decrease because it is negative

[tex]\%Decrease= 20\%[/tex]

Solving (b):

Laptop has the best reduced price  because it has a larger percentage decrease

Answer:

pi

Step-by-step explanation:

to convert angles to radians you must multiply the angle measurement by the formula pi/180

180 x pi/180

the 180s cancel out and you are left with pi

3.142rad × 180/π = 180°

Answer:

Person 3 earns the most money every year

Step-by-step explanation:

Answer:

Person 3 makes the most money every year.

Step-by-step explanation:

Just analyze the graph. Options A and C can be easily eliminated. We're left with options B and D. We know it's going to be option D because person 3 can't make twice as much money as person 1, since person 1 made $9.00 and person 3 made $15.00.

Step-by-step explanation:

For all the recent strides we’ve made in the math world, like how a supercomputer finally solved the Sum of Three Cubes problem that puzzled mathematicians for 65 years, we’re forever crunching calculations in pursuit of deeper numerical knowledge. Some math problems have been challenging us for centuries, and while brain-busters like the ones that follow may seem impossible, someone is bound to solve ‘em eventually. Maybe.

For now, take a crack at the toughest math problems known to man, woman, and machine.

1. The Collatz Conjecture



DAVE LINKLETTER

Earlier this month, news broke of progress on this 82-year-old question, thanks to prolific mathematician Terence Tao. And while the story of Tao’s breakthrough is good news, the problem isn’t fully solved.

A refresher on the Collatz Conjecture: It’s all about that function f(n), shown above, which takes even numbers and cuts them in half, while odd numbers get tripled and then added to 1. Take any natural number, apply f, then apply f again and again. You eventually land on 1, for every number we’ve ever checked. The Conjecture is that this is true for all natural numbers.

Tao’s recent work is a near-solution to the Collatz Conjecture in some subtle ways. But his methods most likely can’t be adapted to yield a complete solution to the problem, as he subsequently explained. So we might be working on it for decades longer.

The Conjecture is in the math discipline known as Dynamical Systems, or the study of situations that change over time in semi-predictable ways. It looks like a simple, innocuous question, but that’s what makes it special. Why is such a basic question so hard to answer? It serves as a benchmark for our understanding; once we solve it, then we can proceed to much more complicated matters.

The study of dynamical systems could become more robust than anyone today could imagine. But we’ll need to solve the Collatz Conjecture for the subject to flourish.

Answer:

D

Step-by-step explanation:

Which expression has a lesser value than -10?

a. 8+ (-12)= -4

b. – 14 – 2 + 8= -16+8= -8

c. 4-(-12)= 16

d. - 2 +(- 12) + 2 = -12

Answer:

Step-by-step explanation:

a.

8 +(-12) = 8-12 = -4

-4 > -10

b.

14-2+8 = 12+8 = 20

20 > -10

c.

4-(-12) = 4+12 = 16

16 > -10

d.

-2+(-12)+2 = -2-12+2 = -14+2 = -12

-12 < -10

Answer:

The answer is 8.

Step-by-step explanation:

He is guaranteed to make $240 between 2 and 6 pm every Saturday afternoon. For each time that both of the 2 customers booked for the same hour does not cancel, he earns only $20. Considering that the probability of cancellation is 25%, if he books 8 customers for the 4 hour period on Saturday afternoon, he is making an extra $80 which bumps up his total earnings to $320. If he accepts any booking after 8, each is going to cost him $40. So the total number of reservations he should take is 8.

I hope this answer helps.

Answer:

150

Step-by-step explanation:

20 percent of 150 is 30.

To check the answer... 150 times 0.2 is 30.

Answer:

150

20 percent of what number equals 30; Answer: 150.

Step-by-step explanation:

20% of what is 30?

Written using the formula: X = 30 ÷ 20%

Convert the percent to a decimal.

20% ÷ 100 = 0.2.

X = 30 ÷ 0.2.

X = 150.

So 20% of 150 is 30.

Answer:  1) 70°  2) x = 55

Step-by-step explanation:

1) If m∠1 = 70°,then m∠8 = 70°.

Because m∠8 is the vertical angle of m∠5, and m∠5 is the corresponding angle of m∠1, which means that m∠8 = m∠1 = 70°. And also m∠1 and m∠8 are alternate exterior angles, they equal to each other.

2) m∠4 = 70°, and m∠7 = 2x, then m∠4 + m∠7 = 180°,because they are consecutive interior angles.

m∠4 + m∠7 = 180°

70 + 2x = 180

2x = 110

x = 55

Answer:

It depends on the number of charms that your bracelet can have.

here we need to count the number of selections that we have, and the number of options for each one of these selections.

So if we can have only one charm, we have only one selection, and for that selection, we have 9 options, then there are 9 different one-charm bracelets.

If each bracelet can have 2 charms then we have two selections.

For the first selection, we have 9 options,

If each charm can be selected only one time, then for the next selection we will have 8 options, now the total number of combinations is equal to the product between the numbers of options for each selection, so here the total number of combinations is:

C = 9*8 = 72

If we can select 3 charms, then:

first charm = 9 options

second charm = 8 options

third charm = 7 options

Total number of combinations = 9*8*7 = 504 combinations.

Notice that we can not give an exact answer because we do not know the number of charms in each bracelet and we do not know if a charm can be selected multiple times or only one, but here you could see the general way to solve this kind of problems.
