Answer:

20%

Step-by-step explanation:

Divide 3 by 15 to get 1/5. If you divide 1 by 5, you will get a decimal answer of 0.2. To convert a decimal to a percent, you must multiply the decimal by 100, which basically means to move the decimal place to the right twice. You will then get the product and final answer of 20%.

We are given the Set: {Red, Green, Blue}

Number of Subsets of the Set:

Number of Subsets of a set is also known as the power of that set

The power of a set is denoted as: 2ⁿ (where n is the number of elements of the set)

Power of the given set:   2³ = 8 subsets

All the subsets of the Given set (The Power Set):

{ ∅, {Red}, {Green}, {Blue} , {Red, Green} , {Green, Blue}, {Blue, Red} , {Red, Green, Blue} }

Answer:

Subtration property of Equality

Step-by-step explanation:

B + 7 = 15

   - 7    - 7

B = 8

The equation B + 7 = 15 becomes B = 8 by subtraction property of equality thus option (C) is correct.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use b.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given equation,

B + 7 = 15

Subtract 7 on both sides,

B + 7 - 7 = 15 - 7

B = 8

Hence "The equation B + 7 = 15 becomes B = 8 by subtraction property of equality".

This question is incomplete, the complete question is;

A general reaction written as A + 2B → C + 2D is studied and yields the following rate law: ∆A/∆t = k A².

The initial concentration is 1.000 M and t½=20.00 s.

How long will it take for the concentration to reach 0.0500 M

Answer:

it will take 380 seconds for the concentration to reach 0.0500 M

Step-by-step explanation:

Given that;

A + 2B → C + 2D

initial concentration A₀ = 1 M

half life t1/2 = 20sec

concentration after t time [A_t] = 0.0500 M

∆A/∆t = k A²

This is a second order chemical kinetics

for this order; t1/2 = 1 / [A]₀K

A₀ is initial concentration, K is rate constant, t1/2 is half life

so,

k = 1 / [A₀]t1/2

we substitute

K = 1 / 1.000 × 20

K = 0.05 mol⁻¹L/sec

for second reaction order

1/[A_t] = kt + 1/[A₀]

kt = 1/[A_t] - 1/[A₀]

we substitute

kt = 1/0.0500 - 1/1.000

kt = 20 - 1

kt = 19

substitute the value of k

0.05 × t = 19

t = 19 / 0.05

t = 380 sec

Therefore it will take 380 seconds for the concentration to reach 0.0500 M

Answer:

e. 23.14 m

Step-by-step explanation:

Perimeter of the figure = ½(perimeter of a circle) + 2(a) + b

= ½(πd) + 2(a) + b

Where,

d = 2 m

a = 9 m

b = 2 m

Plug in the values into the equation

Perimeter of the figure = ½(π*2) + 2(9) + 2

= π + 20

= 23.14 m (nearest hundredth)

Answer:

A is 3, -5

B is -4, -1

Answer:

$475

Step-by-step explanation:

First, we need to subtract 61 from 1011 which given us 950. Then, we divide 950 by 2 to give us the cost of the dryer :)

950 ÷ 2 = 475

This means the cost of the washer is $536 (not relevant to the answer, but at least now you know :) )
