Answer:

  D.  1200 gallons

Step-by-step explanation:

Fractions of the total are given, as is the quantity the difference of those fractions represents. These can be used to write an equation to find the total.

Let g represent the total number of gallons of fuel sold. Then the number of gallons of 87-octane sold is 0.50g, and the number of gallons of 89-octane sold is 0.35g. The difference is said to be 180 gallons:

  0.50g -0.35g = 180

Collecting terms gives ...

  0.15g = 180

Dividing by the coefficient of g, we find ...

  g = 180/0.15 = 1200

The gas station sold 1200 gallons of fuel last weekend.

Additional comment

That's 600 gallons of 87-octane; 420 gallons of 89-octane; 120 gallons of 92-octane; and 60 gallons of 99-octane.

Answer: 4 weeks

Step-by-step explanation:

      To find the answer to this question, we will divide 3 by 3/4 to find the number of weeks one bag will last.

3 / (3/4) = 3 * (4/3) = 12/3 = 4 weeks

          One 3 -pound bag will last the cat 4 weeks.

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

Step-by-step explanation:

You count 4 units to the left and the right of 7

Step-by-step explanation:

1. we can find the slope of the line using this formula:

\(\frac{y_2-y_1}{x_2-x_1}\)

y2, y1, x2, x1 are constants from the two coordinates given, so we just plug them into the formula

\(\frac{-13-19}{-1-3}\)

now we evaluate on both ends of the fraction

\(\frac{-32}{-4}\)

simplify

\(8\)

the slope is 8

2. we are given a graph which means we can simply count the slope

the slope means:

\(\frac{rise}{run}\)

which is the change in y over the change in x , this means that we can start at a coordinate and count the slope

using this method, we get a slope of 2

3. the slope is the change in y over the change in x. the y values are decreasing by -8 while the x values are increasing by ones

this means our slope is

\(\frac{-8}{1}=-8\)

4. we just have to use the aforementioned slope formula above

\(\frac{8-(-10)}{0-9}\)

evaluate

\(\frac{18}{-9}\)

simplify

\(-2\)

the slope is -2

Answer:

Step-by-step explanation:

the formula to find the volume in a triangular prism that only gives you the base area and the height is:

V = Base area * height

So the question said that the base area is 20 and the height is 4. SO lets put it into the formula:

V = 20 * 4

Now we solve it :

V = 20 * 4

V = 80

So the volume of the prism is 80 square feet.

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

Here's my method of doing this:

We'll be using logarithms

Our question is:

\((\frac{1}{3})^{2}\) × \((\frac{1}{3})^x\) = \(\frac{1}{729}\)

If we don't want to evaluate any powers at all we'll have to make each term have the same base (so that we can ignore the base — \(\frac{1}{3}\))

we need to figure out what power of a \(\frac{1}{3}\) the \(\frac{1}{729}\) is.

what we can do is the following:

\((\frac{1}{3})^?\) = \(\frac{1}{729}\)

\(3^?\) = 729

If we take the "log" of each, we can find out what power of 3 gives 729.\(log(3^?) = log\ 729\)

We must remember this rule: \(log(a^n) = n \times log(a)\)

\(? \times log 3 = log 729\)

\(? = \frac{log\ 729}{log\ 3}\)

? = 6 (with a calculator)

This means that to get 729, we need to do \(3^6\)

Therefore \((\frac{1}{3})^6 = \frac{1}{729}\)

We can now solve the equation!

\((\frac{1}{3})^{2}\) × \((\frac{1}{3})^x\) = \(\frac{1}{729}\)

\((\frac{1}{3})^{2}\) × \((\frac{1}{3})^x\) = \((\frac{1}{3})^6\)

Since each term of our equation has the same base of  \(\frac{1}{3}\) we can ignore it and just deal with the powers!

We must remember this rule: \(x^a \times x^b = x^{a + b}\)

Using this rule:

\((\frac{1}{3})^{2}\) × \((\frac{1}{3})^x\) = \((\frac{1}{3})^6\) becomes...

\(2 + x = 6\)

\(x = 6 - 2 = 4\)

Answer:

c=11h+5 and c=16h

Step-by-step explanation:

(h = hours, c = cost)

Looking at A),

c=11h+5

We can insert 2 in for h:

27 = 11 × 2 + 5

Lets try inserting 3:

38 = 11 × 3 + 5

Therefore, A) represents the problem correctly.

Lets look at B),

c=16h

Lets insert 2 in for h:

27 = 16 × 2

Now 3:

38 = 16 × 3

Therefore, B) also represents the problem correctly.

Lets look at C),

c=5h+11

Inserting 2:

21 = 5 × 2 + 11

21 is not the proper price, so this equation does not represent the problem correctly.

Lastly, lets look at D),

h=11c+5

This equation is not correct because it is not trying to solve for c, it is trying to solve for h.

Therefore, A) and B) represent the total cost of renting a canoe for h hours.

Answer:

The experimental probability of rolling a 2 or a 3 is 2/9 or 0.222222 (go as long as you like :D)

Step-by-step explanation:

Total number of times cube roller = T = 360,

we have 96 ones, 31 twos, 49 threes, 76 fours, 45 fives, and 63 sixes

The probability of rolling a 2 is,

since we get 31 twos out of 360 rolls,

P(2) = 31/360

The probability of rolling a 3 is,

since we get 49 threes out of 360 rolls,

P(3) = 49/360

the experimental probability of rolling a 2 or a 3 is the sum of these two,

so,

P(2 or 3) = P(2) + P(3) = 31/360 + 49/360 = 80/360 = 2/9

P(2 or 3) = 2/9

In decimal form, P(2 or 3) = 0.2222222

The experimental probability of rolling a 2 or a 3 is 2/9 or (0.2222) .

The number of times a 2 or a 3 was rolled is the sum of the occurrences of twos and threes,

P(2) = 31

P(3) = 49

P(2) + P(3) = 31 + 49 = 80.

The total number of rolls is given as 360.

Now, calculate the experimental probability:

Experimental probability of rolling a 2 or a 3 = Number of times a 2 or a 3 was rolled / Total number of rolls

P(2 or 3) = 80 / 360

After simplifying the fraction:

Experimental probability of rolling a 2 or a 3 = 2/9

Therefore, the experimental probability of rolling a 2 or a 3 is 2/9.
