The expression represented by 21 increased by twice Gail's height is 21 + 2g

Expressions are mathematical statements that are represented by variables, coefficients and operators

The expression is given as

21 increased by twice Gail's height

Where

g represents Gail's height

So, we have

21 increased by twice Gail's height ⇒ 21 increased by twice g

Twice means 2*

So, we have

21 increased by twice Gail's height ⇒ 21 increased by 2g

increased by means +

So, we have

21 increased by twice Gail's height ⇒ 21 + 2g

Hence, the expression represented by 21 increased by twice Gail's height is 21 + 2g

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.

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

The isolated value of h is found to be V/πr²

The three-dimensional solid shape of a cylinder is made up of two parallel bases connected by a curved surface. These bases have the shape of a spherical disc. The axis of the cylinder is a line drawn through the centre or connecting the centres of two circular bases. The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula πr²h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. Any substance that can fill the cylinder consistently with liquid or another material may be used as the component.

According to given formulae:

V=πr²h

On dividing both side with πr² we get

⇒V/πr²=πr²h/πr²

(Solving R.H.S)

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

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.

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

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

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

The quadratic equation is an equation of the form ax^2 + bx + c =0. Note that the quadratic equation is a polynomial of degree two. This implies that the highest power of x in the quadratic function is power two.

The quadratic formula is given by x = -b ± √b^2- 4ac/2a. The discriminant can be used to obtain the nature of the roots of a quadratic equation. If the roots are real and positive we would have a positive discriminant. If the value of the discriminant is negative then it implies that the roots of the equation are imaginary.

The discriminant can be given as √b^2 - 4ac. The statements that are true about the quadratic formula are;

There will be a 6% rise using the 0.9646 multiplier, then a 9% reduction.

Simply said, a multiplier is a factor that increases the basic value of another object. For example, a 2x multiplier would double the initial value. On the other hand, a multiplier of 0.5x would actually cut the basic amount in half. In finance and economics, multipliers come in a wide variety.

Say that Number is 100N.

growth of 6%

= (6/100)100N

= 6N

Number following reduction: 100N + 6N = 106N

9% lessening

= (9/100)106N

=954N/100

= 9.54N

Final result after reduction = 106N - 9.54N

=96.46N

=9646N/100

= 9646 * 100N/100 * 100

= 9646 * 100N/10000

= 0.9646 * 100N

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.
