Tyra solved the quadratic equation x2-10x -24 = 0by factoring. Her work is shown below:
Step 1: x2-10x -24 = 0
Step 2: x2-4x - 6x - 24 = 0
Step 3: (x2-4x) + (-6x - 24) = 0
Step 4: x(x-4) - 6(x - 4)=0
Step 5: (x-4)(x-6)=0
Step 6: x-4 = 0, x-6 = 0
Step 7: x=4 or x = 6
Step 8: 4, 6

Tyra did not find the correct solutions. Investigate the steps, decipher her mistakes, and explain how to correct Tyra’s work.

Answer:

100

Step-by-step explanation:

1000/50 = 20

5*20 = 100

Answer:

I'm am guessing 15 times as their are 4 choices so 25% percent chance and 60 spins. So 60 times 25% equals 15.

Answer: the relative frequencies in the table are reasonably close.

Step-by-step explanation:

Theoretically relative frequency for all numbers are 0.25. If cube is cast

100 times there my be small fluctuations.

The probability that it will be watermelon flavored is -

P{E} = 1/5.

Given is a bag of jellybeans has 20 watermelons jellybeans, 45 sour apple jellybeans, 30 orange jellybeans and 5 cotton candy jellybeans.

We can write the probability as -

P{E} = (20)/(20 + 45 + 30 + 5)

P{E} = 20/100

P{E} = 1/5

Therefore, the probability that it will be watermelon flavored is -

P{E} = 1/5.

Answer:

Step-by-step explanation:

x^3+7x^2+5x^2+35x

= x^3+12x^2+35x

Answer:

x³ + 12x² + 35x

Step-by-step explanation:

"What is (x² + 5x) multiplied by (x + 7)?

First, we can convert this into an algebraic expression!

This can be written as:

(x² + 5x)(x + 7)

We can use the FOIL Method for multiplying binomials.

FOIL: First, Outer, Inner, Last

"A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product. Inner means multiply the innermost terms in the product, Last means multiply the terms which occur last in each binomial."

FOIL: First: x² × x

x² × x = x³

FOIL: Outer: x² × 7

x² × 7 = 7x²

FOIL: Inner: 5x × x

5x × x = 5x²

FOIL: Last: 5x × 7

5x × 7 = 35x

Add Everything Together!

x³ + 7x² + 5x² + 35x

Simplify:

x³ + 12x² + 35x

Answer:

2.40$ dollars.

We find 20% of 3.00$, which is 0.6$ we then subtract that amount by the normal cost which is 3.00$, so we have an equation that looks like this 3.00$ - 0.6$ = 2.40$ dollars.

Answer:

First combination: One $5 bill, one $1 bill, two quarters and one dime.

Second combination: One $5 bill, one $1 bill, two quarters and two nickles.

Step-by-step explanation:

I highly suggest reading it to make sure you understand it

Okay so for this one you're going to want to do 20.00-13.40. The answer to that is 6.60

So we have to work with $6.60

Now lets think of the obvious/easiest.

A $5 bill is going to be our best friend in this.

We have to do

6.60-5.00=x

(Don't freak out about x, it's just our place marker!!)

The reason we do 5.00 is because that's what $5 is.

So let's solve now.

6.60-5.00=1.60

So x=1.60

But you don't have to worry about x, I'm just explaining it from before.

So we have to keep in mind that we used one $5 bill. Now let's use one $1 dollar bill.

1.60-1.00=0.60

So now we only have to figure out how to get 60 cents from any of the coins.

A quarter is 25 cents so lets use two of those

25+25=50

60=50=10

Lets recap on everything we've used so far.

We've used one $5 bill, one $1 bill, and two quarters.

Now we're going to add a dime to the mix.

A dime is worth 10 cents.

So for the first combination we used: One $5 bill, one $1 bill, two quarters and one dime.

Now our second combination is going to be really easy.

We can use almost everything the exact same, we're only going to switch up the dime part.

1 dime = 2 nickles

Nickles are worth 5 cents

So we take out the dime and replace it with two nickles.

So for the second combination we use: One $5 bill, one $1 bill, two quarters and two nickles.

2) |2-(-3)| = |2+3| = 5

3) (base x height)/2 = (5 x 4)/2 = 10

Step-by-step explanation:

Answer:

$36.38

Step by step explanation:

First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.

This gives us $0.40.

To then find out fifteen percent of $40, you then times $0.40 by 15.

This gives us 6 dollars.

Now, to work out the discount, we take 6 from 40.

$40 - $6 = $34

Now we have to work out the tax.

Again, we have to work out what 1% of $34 is.

This gives us $0.34

Then times that by 7 to find 7%

0.34 x 7 = $2.38

Since this is tax we have to add instead of subtracting.

$34 + $2.38 = $36.38 as the final bill.

Step-by-step explanation:

Simplifying

3x + -1s = r

Reorder the terms:

-1s + 3x = r

Solving

-1s + 3x = r

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-1s + 3x + -3x = r + -3x

Combine like terms: 3x + -3x = 0

-1s + 0 = r + -3x

-1s = r + -3x

Divide each side by '-1'.

s = -1r + 3x

Simplifying

s = -1r + 3x

Answer:

63 degrees Celsius

Step-by-step explanation:

because the line in the middle of 60 and 70 is 65 but the red does not go to that line but it is in the 60s so therefore the answer is C)65degrees Celsuis

Answer:

The correct answer is C) 11 | 2 = 112

Step-by-step explanation:

That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:

112, 112, 115, 118.

The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.

Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)

Answer:

7?

Step-by-step explanation:

72/10 squares = about 7

Answer:

The volume of this shape is 41 inches sq. :)

Step-by-step explanation:

7 x 3 = 21

2 x 2 = 4/2 = 2

2 x 2 = 4/2 = 2

2 x 2 = 4/2 = 2

2 x 2 = 4/2 = 2

2 x 3 = 6

2 x 3 = 6

21 + 2 + 2 + 2 + 2 + 6 + 6 = 41

Answer:

544 cm^2

Step-by-step explanation:

You can see that the figure is made of 6 different rectangles, which would become the sides of the prism if it was 3D.

The top rectangle has a length of 16 cm and a width of 8 cm. 16 x 8 = 128 so this side has an area of 128 square cm

The one directly below that has the same length (16 cm) and a width of 6 cm. 16 x 6 = 96 so its area is 96 square cm

On either side of the previous one there is a 6 by 8 rectangle. 6 x 8 = 48. Remember, there are two sides with an area of 48 cm^2

Below that we have another 16 by 8 rectangle and then another 16 by 6 rectangle.

So your total surface area would be 128 + 96 + 48 +48 + 128 + 96

or 544 square cm

Answer:

14 hours

Step-by-step explanation:

percent of a number

28% of 50

(OR, there is another way)

you could switch it and do 50% of 28, either way you get the same answer.

50% of 28 is 14.

***if there is any percent problem where it is something like 22% of 100 or 78% of 50, you can flip it to say 100% of 22 or 50% of 78.
