The rate of change in gas usage is 34.70 miles per gallon.

The rate of change is the total gallons used for every one mile travelled. To determine the rate of change, divide the miles driven by the gallons used.

Division is the mathematical operation that is used to determine the quotient of a number. It involves grouping a number into equal parts using another number. The sign used to represent division is ÷.

Rate of change = miles driven / gallons used

1041 / 30 = 34.70 miles per gallon

1596. 2 / 46 = 34.70 miles per gallon

1665.6 / 48 = 34.70 miles per gallon

By applying the distributive property, the equivalent expression to 3v - (7.9w - 9.3) is: 3v - 7.9w + 9.3.

Two expressions are equivalent if they both have equal values when simplified or evaluated.

To apply the distributive property, the term or operation sign outside the parentheses is used to multiply each of the terms that are within the parentheses.

Given the expression, 3v - (7.9w - 9.3)

Apply the distributive property to find an equivalent expression

3v - (7.9w - 9.3) = 3v -(7.9w) - (-9.3)

3v - (7.9w - 9.3) = 3v - 7.9w + 9.3

Therefore, by applying the distributive property, the sign "-" is distributed to get the equivalent expression to 3v - (7.9w - 9.3, which is: 3v - 7.9w + 9.3.

The fractions 16/20, 12/15, and 8/10 are equivalent fractions to 4/5.

When writing equivalent fractions, the numerator and denominator should be multiplied or divided by the same number. This is the reason why when these fractions are simplified, they are reduced to the same value.

Let us understand the two ways in which we can make equivalent fractions:

Now, Divide the denominator or numerator by the same number or multiply the denominator and the numerator by the same number.

So, the equivalent fractions for 4/5 are:

(4/5) × (2/2) = (4 × 2) / (5 × 2) = 8/10

(4/5) × (3/3) = (4 × 3) / (5 × 3) = 12/15

(4/5) × (4/4) = (4 × 4) / (5 × 4) = 16/20

Solution: the number of miles in the taxi ride.= 180 miles

Miles : A unit of length equal to exactly 1.609344 kilometers.

Also equal to 1,760 yards or 5,280 feet.

The average walking speed is 3 miles per hour (so it takes about 20 minutes to walk 1 mile).

The taxi company charged a pick-up fee of $4.60

The taxi company charged $0.50 per mile.

The total fare was $13.60

The total fare = pick-up charged + traveling charged

the number of miles in the taxi ride = m

$13.60= $4.60 +  m x $.50

$13.60-$4.60 = $.50m

9 =.50 m

9 /.50 = m

900/5 = m

180 = m

the number of miles in the taxi ride.= 180 miles

If an angle is acute, then its supplement is an obtuse angle (true).

An acute angle is an angle that has a measurement that is below 90 degrees (right angle).

The measurement of an obtuse angle is less than 180 degrees but more than angle 90 degrees (right angle).

The supplement of an angle is the measure of that angle subtracted from 180 degrees.

For example, if an acute angle measures 30°, therefore:

The complement of 30° = 90 - 30 = 60°. 60° is also an acute angle.

The supplement of 30° = 180 - 30 = 150°. 150° is an obtuse angle.

Therefore, we can conclude that: if an angle is acute, then its supplement is an obtuse angle (true).

For graph number 13:

We can see that the domain is: {-3, 3} the range is: R: {-4, 2} this is not a function

For a relation that maps elements x into elements y, we define the domain as the set of the inputs and the range as the set of the outputs. And we say that the relation is a function if each input is mapped into, at most, one output.

If you look at the graph 13 you can see several points, which are of the form (x, y) and are:(-3, 2), (3, 2), (-3, -4), (4, -4)And it makes a little square.

Then you can see that the inputs are -3 and 3, so the domain is:

x=11

Step-by-step explanation:

the perimeter is the sum of all sides.

it is clearly a symmetric figure.

I assume the sqrt(36) is the whole baseline (incl. the left and right x).

so, we have

sqrt(8) + 2x = sqrt(36) = 6

1/2 × sqrt(8) + x = 3

sqrt(1/4 × 8) + x = 3

sqrt(2) + x = 3

x = 3 - sqrt(2)

to get the inclined sides we use Pythagoras

c² = a² + b²

c being the Hypotenuse, a and b being the legs of the right-angled triangle.

so,

side² = sqrt(8)² + (3 - sqrt(2))² = 8 + (9 - 6×sqrt(2) + 2) =

= 19 - 6×sqrt(2)

each inclined side is

sqrt(19 - 6×sqrt(2))

The numeric values for the function are given as follows:

A. f(a) = 9a - 9.

B. f(a + h) = 9a + 9h - 9.

C. f(a + h) - f(a) = 9h.

D. (f(a + h) - f(a))/h = 9.

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the function is given by:

f(x) = 9x - 9.

At x = a, the numeric value is given by:

f(a) = 9(a) - 9 = 9a - 9.

Hence:

f(a) = 9a - 9.

At x = a + h, the numeric value is given by:

f(a + h) = 9(a + h) - 9 = 9a + 9h - 9.

Hence:

f(a + h) = 9a + 9h - 9.

Subtracting these values, we have that:

f(a + h) - f(a) = 9a + 9h - 9 - 9a + 9 = 9h.

Hence:

f(a + h) - f(a) = 9h.

Dividing by h, we have that:

(f(a + h) - f(a))/h = 9h/h = 9.

Hence:

(f(a + h) - f(a))/h = 9.

Hence, the fraction of calories consumed during breakfast and lunch can be calculated thus :

1 - 2/3 = 1/3

Let the total amount of calories consumed per day = c

1/3 × c = 750

c/3 = 750

The total length between the two fences is 136 ft, and the total cost is 164.56 dollars.

We have a square garden with a perimeter of 60ft. Then if the sidelength of the square is S, we have that:

60ft = 4*S

S = 60ft/4 = 15ft

We know that the first fence is around the perimeter of the garden, so the length of the first fence is exactly 60ft.

Now, the other fence is 2ft away from the first fence, so it forms a square of sidelength of:

15ft + 2*2ft = 19ft

Then the perimeter of this square is:

P = 4*19ft = 76ft

This means that the length of the second fence is 76 ft.

So the total length of fence is 76ft + 60ft = 136ft

And the cost is $1.21 per ft, then the total cost for the fence is:

Step-by-step explanation:

Answer:  1,777

Step-by-step explanation:

If you have applied for two jobs a and b and the probability that you get an offer for the job a is 0.25 and the probability of being offered job b is 0.20, then the probability that you will be offered both jobs is 0.05.

Probability is a term used in mathematics that is concerned with the numerical illustration of the possibility of an event to take place. Its value is between 0 and 1 where 0 illustrates the impossibility of the event to take place while 1 illustrates the certainty of an event to take place.

As the probability of both the jobs are not dependent on each other, the probability that both jobs will be offered can be calculated by the formula;

P(A∩B) = P(A) × P(B)

Here, P(A∩B) represents the probability of both the events to take place together

As P(A) is equal to 0.25

P(B) is equal to 0.20

P(A∩B) = (0.25)(0.20)

P(A∩B) = 0.05

Therefore, 0.05 is the probability that both jobs will be offered.

Answer:

50.28 m²

Step-by-step explanation:

Area of a circle = pi r²

= 50.28 m²

Part A: Expression to represent the total amount of juice left in the jar : (0.25 +0.30 + 0.75) - 0.20

Part B: Simplifying above expression using properties of addition and subtraction gives that total amount of juice left is  1.1 liter.

An expression is a group of terms consisting of numbers and mathematical operators ( +, -,*,/) and "=" is not there.

Given that a  jar contains 0.25 liter of apple juice, 0.30 liter of grape juice, 0.75 liter of pineapple. Melissa then drank 0.20 liter of the mixture.

Therefore, total juice in the jar before Melissa drank it = quantity of (apple juice + grape juice + pineapple juice ) = (0.25+ 0.30+0.75) liters

After Melissa drank 0.20 liter juice left = total  juice before - 0.20

Thus, Expression to represent the total amount of juice left in the jar is: (0.25 +0.30 + 0.75) - 0.20

And it can be solved as (0.25 +0.30 + 0.75) - 0.20 = (0.55+0.75)-0.20

                                                                                   = 1.30-0.20 = 1.1 liter

Thus, after simplifying expression we get that the left juice in the jar is 1.1 liter.
