Answer:

27

Step-by-step explanation:

27

Explanation:

"Percent" or "%" means "out of 100" or "per 100", Therefore 18% can be written as  

18 /100 .

When dealing with percentage, the word "of" means "times" or "to multiply".

Finally, lets call the number we are looking for "n".

Putting this altogether we can write this equation and solve for  "n "

while keeping the equation balanced:

n  =  18 /100  ×  150

n  =  2700 /100

n  =  27

27 is 18% of 150

The value of j from the equation h-10/j=k is equal to 10/(h-k).

Given that the equation is h-10/j=k.

We are required to find the value of j from the given equation.

Equation is a relationship between two or more variables that are expressed in equal to form. It may be a linear equation,quadratic equation, cubic equation and many more depending on the power of the variables present in that equation.

The equation is h-10/j=k.

-10/j=k-h

1/j=(k-h)/-10

j=-10/(k-h)

j=10/(h-k)  

(We can eliminate the negative sign by taking negative out from the denominator.)

Hence the value of j from the equation h-10/j=k is equal to 10/(h-k).

The linear equation for the moose population p as a function of t the years since 1986 is P(t) = 380t + 2920.

The equations with two variables where each variable has the largest exponent order of 1 having one, zero, or an infinite number of solutions, and are referred to as linear equations in two variables. A linear equation with two variables has the conventional form ax + by + c = 0, where x and y are the variables. Additionally, the answers can be expressed as ordered pairs, like (x, y).

Linear equations have three main forms which are as follows:

We will consider x on the graph to be years since 1986 and y on the graph to be the number of Moose.

We have two points on the graph:  (6, 5200) and (11, 7100)

Using the slope formula m = (y2 - y1)/(x2 - x1), we can find the slope of this line:

m = (y2 - y1)/(x2 - x1)                

m = (7100 - 5200)/(11 - 6)          

m =  1900/5                            

m = 380                                  

Now, that we have the slope of the line, we can use the point-slope formula (y - y1) = m(x - x1) to find the equation for the line.  Here, we're using the first point, but either point will produce the same answer.

(y - y1) = m(x - x1)                                    

y - 5200 = 380(x - 6)                            

y - 5200 = 380x - 2280                            

y - 5200 + 5200 = 380x - 2280 + 5200    

y = 380x + 2920                                    

Since the equation that is being sought is supposed to be in terms of P and t, We will replace y with P and x with t.

Hence, the equation will be P(t) = 380t + 2920.

The coffee reaches t ≈ 12 minutes a temperature of 150◦F.

T(t) = temperature of the coffee cup t minutes after being placed in the roomTs is the ambient temperature.T0 indicates the coffee cup's beginning temperature.

(a).  Using the given information, we have T(t) = 70 + (160 - 70)e-kt

= 70 + 90e-kt

T(5) = 70 + 90e-k(5) = 112.5

So, 90e-5k = 42.5

e-5k = 0.47222222

-5k = ln(0.47222222)

 k = 0.15      Temperature after 10 minutes = T(10) = 70 + 90e-0.15(10)

According to Newton's law of cooling, a body's rate of heat loss is inversely related to the temperature difference between it and its surroundings. The law is frequently qualified to state that the tiny temperature differential and the consistency of the heat transmission mechanism must exist. As a result, it is the same as asserting that the heat transfer coefficient, which mediates between heat losses and temperature variations, is constant. Due to the fact that the thermal conductivity of the majority of materials very slightly depends on temperature, this requirement is typically satisfied in heat conduction (where it is guaranteed by Fourier's law). Newton's Law is applied in convective heat transfer for forced air or pumped fluid cooling.

Step-by-step explanation:

Assume the number of double matches is x (matches)

the number of single matches is y (matches)

(Condition: x > 0 and y > 0)

Because there are 13 matches in progress, so:

x + y = 13 (1)

Because there are 38 people playing (4 people on each double match and 2 people on each single match), so:

4x + 2y = 38 (2)

A system of equation is made by combining (1) and (2):

x + y = 13 (1)

4x + 2y = 38 (2)

Take (2) - 2×(1):

=> 2x = 12

=> x = 6

Substitute the result on (1)

=> y = 7

So there are 6 double matches and 7 single matches being played

Step-by-step explanation:

Compute the slope of the line through the following points:

p_1 = (1, -1) and p_2 = (-8, -7)

The slope of the line through (x_1, y_1) and (x_2, y_2) is:

(y_2 - y_1)/(x_2 - x_1)

Substitute (x_1, y_1) = (1, -1) and (x_2, y_2) = (-8, -7):

= (-7 - -1)/(-8 - 1)

-8 - 1 = -(8 + 1):

= (-7 - -1)/(-(8 + 1))

8 + 1 = 9:

Step-by-step explanation:

By using Pythagorean theorem, the shortest distance between planet Q and planet R is 1.25 × 10⁷ kilometers (12.5 million kilometers).

The picture shows the geometry between three planets, which represents the three vertices of a right triangle, the straight line distance between the points Q and R represents the hypotenuse of the right triangle. The hypotenuse can be found by using the Pythagorean theorem:

QR = √(PQ² + PR²)

Where QR is the hypotenuse of the right triangle, in kilometers.

If we know that PQ = 3.5 × 10⁶ km and PR = 1.2 × 10⁷ km, then the distance between planet Q and planet R is:

QR = √[(3.5 × 10⁶ km)² + (1.2 × 10⁷ km)²]

QR = 1.25 × 10⁷ km

x - intercept is non - existent

The parabola opens downward.

13) We are given the parabolic function;

y = -x² + 2x - 6

x of vertex = x of axis of symmetry: x = -b/2a = -2/(2 * -1) = 1

y of vertex; y = f(1) = -(1)² + 2(1) - 6 = -5

Vertex = (1, -5)

y - intercept = -6

x - intercept is at y = 0 and as such are; (1 + √-5) and (1 - √-5)

Since a < 0, the parabola opens downward.

14) We are given the parabolic function;

y = -3(x - 2)² + 12

y = -3(x² - 4x + 4) + 12

y = -3x² + 12x - 12 + 12

y = -3x² + 12x

x of vertex = x of axis of symmetry: x = -b/2a = -12/(2 * -3) = 2

y of vertex; y = f(2) = -3(2)² + 12(2) = 12

Vertex = (2, 12)

y - intercept = 0

x - intercept is at y = 0 which is x = 4

Step-by-step explanation: To solve the height of the triangle we can use the Area formula and substitute the values given to solve for heigh.

A = ( b * h ) / 2

17.5 = (7 * h) / 2

17.5 (*2) = 7 * h

(Remember that everything done to one side has to be done to both. We can multiply by 2 on both sides to eliminate the 2.)

35 = 7 * h

35/7 = h

The probability that a five-card hand will contain a straight = 5/1274

There are 52 cards in a deck from which each 13 cards are from 4 different suits (clubs, diamonds, spades and hearts) in a game of poker.

Each 13 cards from high to low are Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King. So a straight of five cards, i.e., five cards in unbroken numerical sequence would be got only from 10 cards in a sequence.

So the possible ways to get a single straight five from all four suits = [tex]4^5[/tex]

Now as we doesn't need all 5 cards from a single suit, we can ignore 4 ways from the above number. i.e.,  [tex]4^5-4 = 1020[/tex] ways.

Hence the possible ways to get a straight five from 10 cards from all four suits = 10 x 1020 = 10200 ways

Total number of ways to select 5 cards from 52 cards = 52C5

Answer:

2(x+y)=98 is the answer.

The measure of the angles ( 15y - 48 )°, ( 8x - 1 )°, and ( 11x - 25 )° are 165°, 15°, and 63° respectively.

The lines j and k are parallel and lines l and m are parallel.

Consider the figure,

( 8x - 1 )° ≅ 1, corresponding angles

1 ≅ 9, corresponding angles

9 ≅ ( 11x - 25 )°, vertical angles

Therefore,

m∠ 1 = m∠ 9

m∠9 = ( 8x - 1 )°

So,

( 8x - 1 )° = ( 11x - 25 )°

Subtracting 8x from both sides of the equation.

11x - 25 - 8x = 8x - 1 - 8x

3x - 25 = - 1

Adding 25 on both sides of the equation.

3x - 25 + 25 = - 1 + 25

3x = 24

Dividing each side of the equation by 3

( 3x/3 ) = ( 24/3 )

x = 8

Now, the angle made by a straight line is 180°.

Therefore,

( 8x - 1 )° + ( 15y  - 48 )° = 180°

( 8 × 8 - 1 )° + ( 15y - 48 )° = 180°

15° + 15y - 48° = 180°

15y - 33° = 180°

Adding each side of the equation by 33°.

15y - 33° + 33° = 180° + 33°

15y = 213°

Dividing each side of the equation by 15

( 15y/15 ) = ( 213/15 )°

y = 14.2°

So, the measure of the angles are:

( 15y  - 48 )° = ( 15 × 14.2 - 48 )° = ( 213 - 48 )° = 165°

( 8x - 1 )° = ( 8 × 8 - 1 )° = 15°

( 11x - 25 )° = ( 11 × 8 - 25 )° = ( 88 - 25 )° = 63°
