Liz is using the distributive property to evaluate the expression 27 (36) by using friendlier numbers. Her work is shown below. Liz's Work 27(36) Step 1 27 (3 + 12) Step 2 27 (3) + 27 (12) Step 3 81 + 324 Step 4 405

Answers

Answer 1

Answer:

Step 1 should have been 27(6 + 30).

Step-by-step explanation:

Given that:

The evaluation of the expression 27(36) by using the distributive property as portrayed by Liz is as follows:

27 (36)

Step 1 = 27 (3+ 12)

Step 2 = 27(3) + 27(12)

step 3  = 81 + 324

Step 4 = 405

What was the first error that Liz made?

From the above first step, we will see that :

27(3+12) was given, which is wrong.

the right step that is supposed to be there is:

27(6 + 30).

so the calculation will be:

Step 1 = 27(6+30)

Step 2 = 27(6) + 27(30)

Step 3 = 162 + 810

Step 4 = 972

When introduced in 1997, a DVD player sold for about $500. Five years later, the average price was $155. Find and interpret the average rate of change in price per year.

Answers

Answer:

-69

Step-by-step explanation:

Use rise over run (change in y/change in x)

The change in y is -345, since that is how much the price decreased

The change in x is 5 years

-345/5

= -69

So, the average rate of change in price per year is -69

Help please also give an explanation

Answers

Answer:

The answer is option A

Step-by-step explanation:

[tex] \frac{a + bc}{wd + f} = g[/tex]

First of all cross multiply

That's

g( wd + f ) = a + bc

Multiply the terms at the left side of the equation

We have

gwd + fg = a + bc

Send fg to the right side of the equation

That's

gwd = a + bc - fg

Divide both sides by dg to make W stand alone

[tex] \frac{gwd}{dg} = \frac{a + bc - fg}{dg} [/tex]

We have the final answer as

[tex]w = \frac{a + bc - fg}{dg} [/tex]

A jar contains 2 caramels, 7 mints, and 16 dark chocolates. What is the probability of choosing a dark chocolate, eating it and then choosing a caramel?

Answers

Answer: dark chocolate 16/25 carmel 1/12

Step-by-step explanation:

there are 16 dark chocolates

to find the probability you have to add up all of your numbers

2+7+16= 25

so the probablity of drawing a dark chocolate is 16/25

repeat the steps but subtract 1 from the total since you ate one you didn't put it back.  

so the probability of drawing a carmel is 2/24 or simplified 1/12

What is the inverse of the function

Answers

Answer:

1/2x -1/2

Step-by-step explanation:

f(x) = 2x+1

y = 2x+1

Switch x and y

x = 2y+1

Solve for y

Subtract 1

x-1 = 2y+1-1

x-1 =2y

Divide by 2

(x-1)/2 = 2y/2

1/2x -1/2 = y

The inverse is 1/2x -1/2

Answer:

[tex]\huge\boxed{h(x) = \frac{1}{2} x - \frac{1}{2}}[/tex]

Step-by-step explanation:

[tex]f(x) = 2x+1[/tex]

Put f(x) = y

[tex]y = 2x + 1[/tex]

Interchange x and y

[tex]x = 2y+1[/tex]

Solve for y

[tex]x = 2y+1[/tex]

Subtracting 1 to both sides

[tex]x-1 = 2y[/tex]

Dividing both sides by 2

Answer:

3.75 cm^2

Step-by-step explanation:

Area of a rectangle = Length x Width.

If we are given that the length is 5 cm and width is 3/4 cm ( you could convert this to a 0.75 if you want to as well ) we can plug this in:

Area = 5 cm x 3/4 cm

Solving for Area we get:

Mrs. Atkins pays $ 1,800 for a new
refrigerator washer, and dryer.
The refregerator cost $ 250 more
than the washer. The dryer costs
half as much as the washer.
How much does the washer cost?
The was her cost:_____

Answers

A: $620

Explanation:
first set your variables:
refrigerator: r
washer: w
dryer:d

next create your equation:
1800= r+w+d

now use what you know to solve the problem. you know how much the refrigerator and dryer cost, so create an equation based off that knowledge.

r = 250 + w
d = 1/2w

now substitute those equations for the variables:
1800 = 250 + w + 1/2w + w
(r) (d)

combine like terms:
1800 = 250 + 2w + 1/2w

1800 = 250 + 2.5w

subtract 250 from both sides:
1550 = 2.5w

divide by 2.5:
w= 620

if you want to check, plug in the w value and see if everything equals 1800:
1800 = 250 + 620 + 1/2(620) + 620
1800 = 870 + 310 + 620
1800 = 1800

it is correct, hope this helps :))

kelly bought some stuffed animals for 6.49 each she also got a box fo chocolate for 8.32 she paid a total of 27.79 to write an equation to find how many stuffed animals kelly purchased

Answers

Answer:

Step-by-step explanation:

She only bought one chocolate so you will subtract 8.32 from her total, 27.79, when you do that you will get 19.47.  You do that so you can know the total of the stuffed animals by them self.  Then all you have left in the total is her stuffed animals so you divide 19.47 by 6.49, when you do that you get three, so that means that she got three stuffed animals.

In the drawing above two rugby players start 41 meters apart at rest. Player 1 accelerates at 2.2 m/s^2 and player 2 accelerates at 1.7 m/s^2. How much time elapses before the players collide?

Answers

Answer:

The time that elapses before the players collide is 4.59 secs

Step-by-step explanation:

The distance between the two players is 41 meters. Hence, they would have total distance of 41 meters by the time they collide.

We can write that

S₁ + S₂ = 41 m

Where S₁ is the distance covered by Player 1 before collision

and S₂ is the distance covered by Player 2 before collision

From one of the equations of kinematics for linear motion,

[tex]S = ut[/tex] + [tex]\frac{1}{2} at^{2}[/tex]

Where [tex]S[/tex] is distance

[tex]u[/tex] is the initial velocity

[tex]a[/tex] is acceleration

and [tex]t[/tex] is time

Since the players collide at the same time, then time spent by player 1 before collision equals time spent by player 2 before collision

That is, t₁ = t₂ = t

Where t₁ is the time spent by player 1

and t₂ is the time spent by player 2

For player 1

[tex]S[/tex] = S₁

[tex]u[/tex] = 0 m/s ( The player starts at rest)

[tex]a[/tex] = 2.2 m/s²

Then,

S₁ = [tex]0(t)[/tex] + [tex]\frac{1}{2} (2.2)t^{2}[/tex]

S₁ = [tex]1.1t^{2}[/tex]

[tex]t^{2} = \frac{S_{1} }{1.1}[/tex]

For player 2

[tex]S[/tex] = S₂

[tex]u[/tex] = 0 m/s ( The player starts at rest)

[tex]a[/tex] = 1.7 m/s²

Then,

S₂ = [tex]0(t)[/tex] + [tex]\frac{1}{2} (1.7)t^{2}[/tex]

S₂ = [tex]0.85t^{2}[/tex]

[tex]t^{2} = \frac{S_{2} }{0.85}[/tex]

Since the time spent by both players is equal, We can  write that

[tex]t^{2}[/tex] = [tex]t^{2}[/tex]

Then,

[tex]\frac{S_{1} }{1.1} = \frac{S_{2} }{0.85}[/tex]

[tex]0.85S_{1} = 1.1S_{2}[/tex]

From, S₁ + S₂ = 41 m

S₂ = 41  - S₁

Then,

[tex]0.85S_{1} = 1.1 ( 41 -S_{1} )[/tex]

[tex]0.85S_{1} = 45.1 - 1.1S_{1}[/tex]

[tex]0.85S_{1} + 1.1S_{1} = 45.1 \\1.95S_{1} = 45.1\\S_{1} = \frac{45.1}{1.95} \\S_{1} = 23.13 m[/tex]

This is the distance covered by the first player. We can then put this value into [tex]t^{2} = \frac{S_{1} }{1.1}[/tex] to determine how much time elapses before the players collide.

[tex]t^{2} = \frac{S_{1} }{1.1}[/tex]

[tex]t^{2} = \frac{23.13 }{1.1}[/tex]

[tex]t^{2} = 21.03\\t = \sqrt{21.03} \\t = 4.59 secs[/tex]

Hence, the time that elapses before the players collide is 4.59 secs

y^2+3y-10=0 please solve

Answers

The Answer is: y=2,5

Answer:

y = -5

y = 2

Step-by-step explanation:

Find 2 factors of -10 that add up to 3

This will be 5 and -2

So, we can factor this:

y² + 3y -10 = 0

(y + 5)(y - 2) = 0

Set each factor equal to 0 and solve:

y + 5 = 0

y = -5

y - 2 = 0

y = 2

So, the solutions are y = -5 and y = 2
