Answer:

$86.40

Step-by-step explanation:

The house Trevor's family lives in has 6 people (including Trevor) and 3 bathrooms. In the past month, each person showered for an average of 480 minutes and used an average 72 liters of shower water (over the entire month). Water costs 0.20 dollars per liter.

How much money did Trevor's family spend, in total, on shower water in the past month?

Total people in Trevor's family = 6

Number of bathrooms = 3

Time each person spent to shower = 480 minutes

Quantity of water each person use per month = 72 liters

Cost of water per liter = $0.20

Total amount spent on shower water = Total people in Trevor's family × Quantity of water each person use per month × Cost of water per liter

= 6 × 72 × 0.20

= $86.40

Total amount spent on shower water = $86.40

Answer:

$7, 657

Step-by-step explanation:

Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. The total initial amount of the loan is then subtracted from the resulting value.

Answer:

12 lbs

Step-by-step explanation:

There are 16 ounces in a pound

192 ounces * 1 pound / 16 ounces = 12 pounds

Step-by-step explanation:

1 pound = 16 ounces

24 pound = 16 x 24 ounces = 384 ounces

1 ounce = 1/16 pounds

192 ounces = 192/16 pounds = 12 pounds

What's the question to the question?

Step-by-step explanation:

x = ??

y = 72 + 40 = 112

x =112 - 180

x = 180-112

x = 68

or = 180 - 72 = 108

180 - 40 = 140

140 - 108 = 32

now

4x²-9

(2x)²-3²

using formula

(2x+3)(2x-3)

other expression is 2x-3.

Answer:

( 2x - 3 )

Step-by-step explanation:

4x² - 9 is a perfect square meaning it can be factored into 2 expressions,

( 2x + 3 ) ( 2x - 3 )

Answer:

The answer si:  

- 16 servings - 6 oz of salmon

- 24 servings - 9 oz of salmon

- 80 servings - 30 oz of salmon

- 100 servings - 37.5 oz of salmon

1 roll is 8 servings and it is also made of 3oz of smoked salmon. That means that 3oz of smoked salmon is needed fo 8 servings.

Now, let's made some proportions:

16 servings:

3 oz is for 8 servings, how much oz is for 16 servings:

3 : 8 = x : 16

x = 3 · 16 ÷ 8 = 6 oz

24 servings:

3 oz is for 8 servings, how much oz is for 24 servings:

3 : 8 = x : 24

x = 3 · 24 ÷ 8 = 9 oz

80 servings:

3 oz is for 8 servings, how much oz is for 80 servings:

3 : 8 = x : 80

x = 3 · 80 ÷ 8 = 30 oz

100 servings:

3 oz is for 8 servings, how much oz is for 100 servings:

3 : 8 = x : 100

x = 3 · 100 ÷ 8 = 37.5 oz

Answer:

a) 81-6

b) 10.4

Step-by-step explanation:

a) assuming that the VAT is 20% of the 68 pounds,

you calculate 120% of 68 (convert percentage to decimal)

= 1,20 * 68 = 81.6 pounds

or

calculate 20% of 68 pounds and add the answer to 68 pounds:

(0.2 * 68) + 68 = 81.6 pounds

b) 20% of 52

first convert the percentage to decimals:

0.2 * 52 = 10.4 pounds

Answer:

Volume of cylinder

= π r² h

OAmalOHopeO

Answer:

The volume of the cylinder would be approximately 392.5 ft^3

Step-by-step explanation:

Just like the volume formulas for a cuboid, the formula for a cylinder is: Vol = (Circle Area)(Height). Since we already have the height value, let's move onto the circle area.

The formula for the area of a circle is: πr^2. The problem only gave us the value for the diameter (10), so to get the radius value, we just need to divide the diameter by 2, and we get a value of 5 ft as our radius. Next, we just need to square root it. So 5 x 5 = 25. Then, we multiply it by π. Because the problem is asking for an approximate answer, we can just assume that π is 3.14. And that gets us a value of 78.5 ft^2 for the area of the circle.

Finally, we just need to multiply the area and the height of the cylinder. So 78.5 x 5 is approx. 392.5 ft^3. Since we don't need to round to the nearest tenths place, we can just leave it alone.

Since I didn't use the exact value of π, the real answer may be a little off of what we got, but if you want to extra precise, you can go ahead and use the actual value of π.

Answer:

(2,0)

Step-by-step explanation:

   2 (x + 2y) = (2)

      2x + 4y = 4

-    2x + 5y = 4

-1y = 0

y = 0

2x + 5(0) = 4

2x = 4

x = 2

Answer:

x=2 y=0

Step-by-step explanation:

solve for y

x+2y=2

x=2-2y

2(2-2y)+5y

4-4y+5y=4

4+y=4

y=0

plug into equation

2x+5(0)=4

x=2

Answer: -6/7

Step-by-step explanation:

[tex]2x/5-3x/4=3/10\\(8x-15x)/20=3/10\\-7x/20=3/10\\-7x=(3/10)*20\\-7x=6\\x=-6/7[/tex]

We have to find,

The required value of x.

Given that,

→ 2x/5 - 3x/4 = 3/10

Then let's solve for the value of x,

→ 2x/5 - 3x/4 = 3/10

→ (8x - 15x)/20 = 3/10

→ -7x/20 = 3/10

→ -7x = (3/10) × 20

→ -7x = 3 × 2

→ -7x = 6

→ [x = -6/7]

Hence, the value of x is -6/7.

Answer:

Step-by-step explanation:

Daniel

Daniel starts with $50 and each week he adds $8. To find out the amount he has in any given week, the following formula would work:

= 50 + 8x

The x is the number of weeks and is multiplied by 8 because the amount of money he has increase by 8 every week.

After 4 weeks he would have:

= 50 + (8 * 4)

= 50 + 32

= $82

Saquon

Applying the same formula:

= 65 + 5x

After 4 weeks:

= 65 + (5 * 4)

= 65 + 20

= $85

Saquon has more money after 4 weeks.

Number of weeks it would take for both of them to have the same amount.

To find this out, equate both formulas and solve for x.

50 + 8x = 65 + 5x

8x - 5x = 65 - 50

3x = 15

x = 15/3

x = 5 weeks

At 5 weeks they will both have:

50 + 8 * 5 = $90

65 + 5 * 5 = $90

Answer:

Range = {5, 7, 9}

Step-by-step explanation:

Range is the set of values that are the results of respective values of x when placed in the function f(x).

[tex] \mathfrak{\blue {\underline{\implies If\: x = 3 }}} [/tex]

f(3) = 2 × 3 - 1

f(3) = 6 - 1

f(3) = 5

[tex] \mathfrak{\blue{\underline{\implies If \:x = 4 }}} [/tex]

f(4) = 2 × 4- 1

f(4) = 8 - 1

f(4) = 7

[tex] \mathfrak{\blue{\underline{\implies If\: x = 5 }}} [/tex]

f(5) = 2× 5 - 1

f(5) = 10 - 1

f(5) = 9

Therefore, the range is the set of all these values :-

Range = {5, 7, 9}

Answer:

Step-by-step explanation:

The key to solving this equation is knowing how to "undo" a natural log. Just like square roots are "undone" by squaring, and cubing "undoes" a cubed root, raising a natural log to the base of e, Euler's number, undoes a natural log. Because this is an equation you have to raise both sides of it to the base of e:

[tex]e^{ln(x+3)}=e^5[/tex]

That leaves us on the left with simply

x + 3

On the right we have a constant. e is not a variable, it is a number. You can find its value on your calculator. Solving for x:

[tex]x=e^5-3[/tex] and

[tex]e^5=148.4131591[/tex], so

x = 148.4131591 - 3 and

x = 145.4132, the first choice listed.

It is given that a recipe of sugar cookies needed [tex]2\frac{1}{2}[/tex] cups of sugar for 36 cookies.

We have to find out the amount of sugar needed for 48 cookies.

What is the unitary method?

The unitary method is a method in which we find the value of a unit and then the value of the required number of units.

As per the question ;

Sugar required for 36 cookies = [tex]2\frac{1}{2}[/tex] cups

Sugar required for 1 cookies

=  [tex]2\frac{1}{2}[/tex] ÷ 36 cups

= [tex]\frac{5}{2}[/tex] ÷ 36

= [tex]\frac{5}{2}[/tex] × [tex]\frac{1}{36}[/tex]

So , the sugar required for 48 cookies will be equal to ;

= [tex]\frac{5}{2}[/tex] × [tex]\frac{1}{36}[/tex] × 48

= [tex]\frac{240}{72}[/tex]

= [tex]\frac{10}{3}[/tex]

or

[tex]3\frac{1}{3}[/tex] cups

Thus , the sugar needed for 8 cookies will be equal to [tex]3\frac{1}{3}[/tex] cups.
