3) A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then

find AB

### Answers

Answer:

AB = 8

Step-by-step explanation:

A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then find AB

Step 1

Find x

BC = AB + AC

8x + 5 = 2x + 4 + 3x + 7

Collect like terms

8x - 2x - 3x = +4 + 7 - 5

3x = 6

x = 2

Step 2

Find AB

= AB= 2x + 4

AB = 2(2) + 4

AB = 4 + 4

AB = 8

the product of 0.43 and 5.024 is greater than 0.43 and less than 5.024 true or false

### Answers

**Answer: True **

**Step-by-step explanation:**

First find the product of 0.43 and 5.024 so see if it is greater than 0.43.

0.43 * 5.024 = 2.16032

2.16032 is indeed greater than 0.43 , 2.16032 > 0.43

And 0.43 is indeed less than 5.024 , 0.43 < 5.024

Meaning that this state is true.

**Answer:**

True

**Step-by-step explanation:**

Product refers to multiplication, the question is telling us to multiply 0.43 and 5.024 so lets do that

0.43 * 5.024 = 2.16032

Now we have to figure out if this fits the criteria. It must be larger than 0.43 but smaller then 5.024

...

...

...

That checks out.

An element with a mass of 650 grams decays by 13.2% per minute. To the nearest minute, how long will it be until there are 220 grams of the element remaining?

### Answers

Answer: 8

Step-by-step explanation:

The **time taken** where there is 220 grams of the **element** remaining should be considered as the **5 minutes. **

Calculation of the time taken:

Since An element with a **mass** of 650 grams **decays** by 13.2% per minute. and there is 220 grams of the element remaining.

So, the mass decays be

= 650 - 220

= 430

Now the total **percentage** be like

[tex]= 430 \div 650[/tex]

= 66.15%

Now the time taken should be

= [tex]66.15\div 13.2[/tex]

= 5 minutes

The **time taken** where there is 220 grams of the **element** remaining should be considered as the **5 minutes. **

What is 26/15 as a whole number?

**Answer:**

1 11/15

**Step-by-step explanation:**

Stephen goes to the fair and buys two funnel cakes and one drink. His total bill is $6.75. A few days later, he goes with a friend and buys three funnel cakes and two drinks. This time his total bill is $11.

Write two equations that could be used to determine how much each funnel cake and drink costs. Use f for the cost of a funnel cake and d for the cost of a drink.

What is the cost of a funnel cake?

What is the cost of a drink?

### Answers

**Answer:**

Let's define the variables:

f = Cost per cake

d = Cost per drink.

"Stephen goes to the fair and buys two funnel cakes and one drink. His total bill is $6.75. "

2*f + 1*d = $6.75

"A few days later, he goes with a friend and buys three funnel cakes and two drinks. This time his total bill is $11."

3*f + 2*d = $11.

Then we have a system of equations:

2*f + 1*d = $6.75

3*f + 2*d = $11.

To solve this, the first step is to isolate one of the variables in one of the equations, let's isolate d in the first equation:

d = $6.75 - 2*f

Now we can replace this in the other equation:

3*f + 2*($6.75 - 2*f) = $11

3*f - 4*f + $13.50 = $11

-f = $11 - $13.50 = -$2.50

f = $2.50

Then the cost of a funnel cake is $2.50

And the cost of a drink can be obtained with the equation:

d = $6.75 - 2*f = $6.75 - 2*$2.50 = $1.75

The cost of a drink is $1.75

Find all values of x in the interval [0, 2π] that satisfy the equation. (Enter your answers as a comma-separated list.)

6 sin2(x) = 3

### Answers

**Answer:**

**(15°, 165°)**

**Step-by-step explanation:**

Given the equation 6 sin2(x) = 3, we are to find the value of x that satisfies the equation in the interval [0, 2π]

**Given**

6 sin2(x) = 3,

Divide both sides by 6

6 sin2(x)/6 = 3/6

sin2(x) = 1/2

2x = sin^-1(0.5)

2x = 30°

x = 30°/2

x = 15°

Since sin is positive in the second quadrant, x2 = 180-15

x = 165°

**Hence the values within the interval are 15 and 165.**

**(15°, 165°)**

2. A shop owner raises the price of a $100 pair of shoes by 50%. After a few weeks,

because of falling sales, the owner reduces the price of the shoes by 50%. A

customer then says that the shoes are back at the original price.

a. What is the mistaken assumption here?

b. Why is that assumption incorrect?

c. What do the shoes actually cost now?

d. By what percent should the shoes be decreased in order to have the price

back at $100?

Kk

### Answers

**Answer:**

the customer is wrong

**Step-by-step explanation:**

when he raised then 50 % they became $150 and then If you do the work 50% of $150 is $75 .

100+%50

150

150-%50

75

The customer is wrong because the** new price** of the shoe is **$75** and not $100.

When the shop owner raises the price of a $100 pair of shoes by 50%, then the new price will be:

=** $100 + (50% × $100)**

= $100 + $50

=** $150**

Then, the owner reduces the price by** 50%**, then the new price will be:

= **$150 - (50% × $150)**

= $150 - $75

= $75

Therefore, the new price is** $75.**

(Car repair) The bill including parts and labor for the repair of your car is shown. From what is given, can you determine how many hours were spent on labor ? Explain.

### Answers

**Answer:**

**2.25 hours or 2 hours and 15 minutes**

**Step-by-step explanation:**

Using the information from the bill shown in the question we can determine the number of hours spent by first subtracting the amount of money spent on parts from the overall total, which would leave us with the total amount spent on labor. Now we would simply divide this by $44 which is how much each hour of labor costs. Finally, this would leave us with the total number of hours of labor that the mechanic put into the car repair.

$384 - $285 = $99

$99 / 44 = **2.25 hours or 2 hours and 15 minutes** (0.25 * 60 minutes)
