The difference between the two points is a vertical displacement of 5 units downward from point T to point V.

The distance formula is used to calculate the distance between two points in a two- or three-dimensional coordinate system. It is derived from the Pythagorean theorem and involves finding the square root of the sum of the squares of the differences between the corresponding coordinates of the two points.

The difference between point T(9, -4) and point V(9, -9) is 5 units in the y-direction. Specifically, the y-coordinate of point V is 5 units less than the y-coordinate of point T. This can be expressed as:

V - T = (9, -9) - (9, -4) = (0, -5)

The measure of ∠FGH is 28 - 4x.

A three-sided polygon with three angles is known as a triangle. It is a basic geometric shape that can be classified based on its sides and angles.

Since G is the midpoint of DF, we have m∠DGF = m∠FGC (vertical angles are equal), so m∠FGD = m∠CGF = (180 - m∠DGF)/2 = (180 - m∠FGC)/2 = m∠GFC. Similarly, m∠FHE = m∠HEC, so m∠FHE = m∠CGF = m∠GFC.

Using angle sum property, we have:

m∠DEF + m∠FED + m∠FDE = 180

60 - 5x + 2(46 + 2x) + m∠FGH = 180

152 + 4x + m∠FGH = 180

m∠FGH = 180 - 152 - 4x

Step-by-step explanation:

The profit for buying pencils for $2 each and selling them for $2.40 is $6.40 and there is no loss.

The profit is the difference between the selling price and the cost price of the pencils. In this case, the profit per pencil is $2.40 - $2 = $0.40.

Since the total sales amount is $40, the number of pencils sold is $40/$2.40 = 16.67, which we can round down to 16 pencils. Therefore, the total profit is 16 * $0.40 = $6.40.

There is no loss in this scenario, as the selling price is higher than the cost price. Loss occurs when the selling price is lower than the cost price.

We have shown that a line L is tangent to a circle C at a point P if and only if L is perpendicular to the line OP.

A line L is said to be tangent to a circle C at a point P if and only if L meets C at P and at no other point besides P. Given a circle centered at a point O, a point P on the circle, and a line L passing through P, we can show that L is tangent to the circle at P if and only if L is perpendicular to the line OP.

Let us assume that L is perpendicular to OP. Then, since L is perpendicular to the radius at P, it is also perpendicular to the circumference of the circle at P. This means that the line L only meets the circumference of the circle at the one point P, and so L is tangent to the circle at P.

Conversely, let us assume that L is tangent to the circle at P. This implies that the line L only meets the circumference of the circle at the one point P. Thus, since the line L must pass through the point P, it must be perpendicular to the line OP.

Therefore, we have shown that a line L is tangent to a circle C at a point P if and only if L is perpendicular to the line OP.

The original number would be 3.

An equation is an expression that shows the relationship between two or more numbers and variables.

Consider that the 10s digit = x

And the units digit = y

x +y = 11                                  

The Sum of the digits = 11

10x + y + 45 = 10y + x            

Then Reversed number is 45 more  than original,

10x - x + y + 45 = 10y              

9x + y + 45 = 10y                    

9x + 45 = 10y - y                    

9x + 45 = 9y

Now, Put x +  y = 11 into the equation just found.

9x + 45 = 9(11 - x)                    

x + 45/9 = 11 - x                      

2x + 5 =     11                          

2x = 11 - 5

2x = 6                                      

x = 6/2

x = 3

Therefore, we have;

x + y = 11

The little monsters will do an overhead press and a squat at the same instant 3 times during the drill.

The process of calculating a value using operands and a math operator is referred to as a "operation" in mathematics. The math operator's symbol has predetermined rules that must be obeyed for the provided operands or integers. The five fundamental operations in mathematics are addition, subtraction, multiplication, division, and modular forms.

The prime factorizations of 12 and 30 are 2² x 3 and 2 x 3 x 5, respectively.

Hence, 2² x 3 x 5 = 60 is the smallest common multiple of 12 and 30.

This means that the little monsters will do an overhead press and a squat at the same instant every 60 seconds.

To find out how many times this will happen during the 200-second drill, we can divide 200 by 60:

200 ÷ 60 = 3 remainder 20

This means that there will be 3 complete cycles of both exercises during the 200-second drill, with an additional 20 seconds left over.

Therefore, the little monsters will do an overhead press and a squat at the same instant 3 times during the drill.

Answer:

(a) The probability that all 4 calls are for medical help can be calculated using the binomial probability formula:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

where:

n is the number of trials (in this case, 4)

k is the number of successes (in this case, 4)

p is the probability of success on a single trial (in this case, 0.81)

Plugging in the values, we get:

P(X = 4) = (4 choose 4) * 0.81^4 * (1 - 0.81)^(4 - 4)

P(X = 4) = 0.5314

Therefore, the probability that all 4 calls are for medical help is 0.5314, rounded to 4 decimal places.

(b) The probability that at least 1 of the calls is not for medical help can be calculated using the complement rule:

P(at least 1 call not for medical help) = 1 - P(all 4 calls for medical help)

We already calculated the probability of all 4 calls being for medical help in part (a), which is 0.5314. So, using the complement rule, we get:

P(at least 1 call not for medical help) = 1 - 0.5314

P(at least 1 call not for medical help) = 0.4686

Therefore, the probability that at least 1 of the calls is not for medical help is 0.4686, rounded to 4 decimal places.

(c) The calculation in part (a) may not be valid if we choose 4 consecutive calls to the station because the 4 consecutive calls being medical may not be independent events. For example, if a large accident or a natural disaster occurs in the area, there may be a higher probability of multiple consecutive medical calls due to the same incident or cause. In that case, the assumption of independence between the events would not hold, and the binomial probability formula would not be applicable.

The surface area of a cuboid is the total area of all of the faces of a cuboid. If, the length (l), width (w), and height (h) of the cuboid

then, use the formula: surface area (SA)=2lw+2lh+2hw.

here, we have,

We know that the formula for the volume of a box is:

V = l*w*h

Where:

l = length

w = width

h = height

The formula of the surface area of a box is:

SA = 2(lw+lh+wh)

Based on the given we know the following:

24 =  l*w*h

and

56 =  2(lw+lh+wh)

If we factor out the given volume, you can come up with 3 numbers that will satisfy the surface area formula:

24 = 6*2*2

Let:

l = 6cm

w =2cm

h =2cm    

Now let's try this on the surface area formula:

56 = 2(6*2+6*2+2*2)

so, 56 = 56

The maximum possible height for the fish tank is  23.749 inches

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

We need to convert the tank capacity from gallons to cubic feet since we know the conversion factor of 1 cubic foot of water = 7.48 gallons:

Tank capacity = 100 / 7.48 cubic feet

= 13.369 cubic feet

Volume of fish tank = Length x Width x Height

= 54 inches x 18 inches x Height

= 972 inches³ x Height

The maximum possible height of the fish tank

Volume of fish tank = Tank capacity

972 cubic inches x Height = 13.369 cubic feet

Height = 13.369 cubic feet / 972 cubic inches

= 0.013753 cubic feet / cubic inches

To convert cubic feet to cubic inches, we multiply by 1728

Height = 0.013753 x 1728

In mathematics, an inequality is a statement that compares two values, expressing that one value is less than, greater than, or less than or equal to, greater than or equal to, or not equal to another value.

The inequality is y - 2 < -5.

To graph the solution on a number line, we start by marking the point where y - 2 equals -5, which is y = -3. Then, since the inequality is less-than, we use an open circle to represent the point y = -3.

Next, we shade all the values of y that make the inequality y - 2 < -5 true. Since y is less than -3, we shade everything to the left of the open circle.

Therefore, the number line that shows the solution to the inequality y - 2 < -5 is:
