Camel can drink 21 gallons of water in 14 minutes.

Given in question,

Gallons of water camel can drink in 10 minutes = 15

 Gallons of water camel can drink in 1 minutes = 15/10

                                                                              = 1.5

Gallons of water camel can drink in 14 minutes = 1.5 * 14

                                                                              = 21

Hence, camel can drink 21 gallons of water in 14 minutes.

The percent change of the worth is 3.26%.

Apples were for sale from a fruit vendor. He has 420 apples and sells 40% of them. How many apples did he have in total when he first started?

Solution: Assume a fruit vendor had x apples in stock.

According to the query,

(100 – 40%) of x = 420

60% of x = 420

60/100 x = 420

X = 700

The fruit vendor, therefore, had 700 apples in all.

Let , the worth is $x.

according to the question, $x + $5 =$158

∴ $x= $153

∴ percent change= (5/153)×100

The value of x in complementary angle is 12.5⁰.

We need to know about complementary angles to solve this problem. The complementary angle is the angle that can make another angle has a value of 90⁰. It can be written as

A + B = 90⁰

where A and B are the complementary angles.

From the question above, the given parameters are

A = 18⁰

B = (8x - 28)⁰

By substituting the given parameters, we can calculate the x value

A + B = 90⁰

18⁰ + (8x - 28)⁰ = 90⁰

8x = 90 - 18 + 28

8x = 100

The probability that at least one person will receive the correct letter is 2/3.

Given data,

Let's say that the letter matching to the envelope is A, B, and C.

Each envelope has exactly one letter inside it once the letters are randomly placed inside.

Aa, Bb, Cc, Aa, Bc, Cb, Ab, Ba, Cc, Ab, Bc, Ca, Ac, Bb, Ca, Ac, Ba, Cb, are all possible combinations.

Thus, the total number of scenarios is 6 (n(S)).

A=(Aa, Bb, Cc), (Aa, Bc, Cb), (Ac, Bb, Ca), (Ab, Ba, Cc), n(A)=4

let A be an event that at least one letter is in its right envelope.

So,

The probability that at least one letter is in the right envelope P(A) = n(S) / n(A) = 4 / 6

= 2 / 3

The correct statement that regarding the angles of triangle is option (C)  m∠C > m∠A > m∠B

The value of p ≥ 3

Consider the value p = 3

The length of the side AB = 4p - 1

= 4×3 - 1

= 12 - 1

= 11 units

The length of side BC = 3p

= 3×3

= 9 units

The length of the side AC = p + 4

= 3 + 4

= 7 units

Then length of AB > length of BC > length of AC

The angles opposite to the side AB, BC and AC are m∠C , m∠A and m∠B

Then  m∠C > m∠A > m∠B

The flowrate of decreasing water is 3.98 cm/min after the water reaches 5cm of its height.

We need to know about the flowrate to solve this problem. The rate can be described as how much water flows in a unit of time. It can be represented by this equation

Q = V / t

where Q is flowrate, V is volume and t is time.

From the question above, the given parameters are

Inverted cone with

Q = 50 cm³/min

R = 4 cm

h = 5 cm

Hence, the rate of decreasing water is

Q = V / t

50 = A . h / t

50 = π . R² . h / t

50 = 22/7 . 4 . h / t

The base of the triangle is 15 meters.

Here, we are given that the height of a triangle is 5 m longer than the base.

Let the height of the triangle be h

Then, the base of the triangle will be = h - 5

Further, we are given that area of the triangle = 150 meter square

We know that area of a triangle = 1/2 × base × height

⇒ 150 = 1/2 × h × (h-5)

150 × 2 = h(h-5)

300 = [tex]h^{2}[/tex] - 5h

[tex]h^{2}[/tex] - 5h - 300 = 0

Now, we solve the above quadratic equation by splitting the middle term.

[tex]h^{2}[/tex] + 15h - 20h - 300 = 0

h( h + 15) - 20( h + 15) = 0

(h - 20) (h + 15) = 0

Thus, h = 20 or -15

But since height cannot be negative, h = 20

⇒ base = h - 5

= 20 - 5

= 15 meters

Thus, the base of the triangle is 15 meters.

For the probability of any particular event occurring is 7 /10 then odds of favoring the event which is not occurring in the form of a: b is equal to

7 : 3.

As given in the question,

Probability of any particular event occurring is equal to 7 /10

Probability of any particular event not occurring is = 1- (7/10)

                                                                                    = (10 -7) /10

                                                                                    = 3/10

Probability of the odds favoring the events which are not occurring

= (7 /10) / (3/10)

= ( 7 × 10) / (3 × 10)

= 7 /3

Odds favoring the events which are not occurring in the form a: b

= 7 : 3

Yes, the points are the vertices of a right triangle and we will prove that by using the Pythagorean theorem.

Remember that the distance between two points (a, b) and (c, d) is:

distance = √( (a - c)² + (b - d)²)

The distance between (-4, 8) and (8, 8) is:

d₁ = √( (-4 - 8)² + (8- 8)²) = 12

The distance between (8, 8) and (-4, 3) is:

d₂ = √( (8 + 4)² + (8- 3)²) = 13

The distance between (-4, 8) and (-4, 3) is:

d₃ = = √( (-4 + 4)² + (8 - 3)²) = 5

if the Pythagorean theorem is true, then the sum of the squares of the two shorter sides must be equal to the square of the larger side, then we must have that:

5² + 12² = 13²

Solving that we get:

25 + 144 = 169
