The fastest vehicle is: the all terrain that can travel at a speed of 72 mi/h

To solve this problem we must perform the following algebraic operations with the given information

Information about the problem:

Calculating the velocity of the all terrain vehicle we get:

v(all terrain vehicle) =  6 * 12mi/h

v(all terrain vehicle) =  72 mi/h

By ordering the velocities from highest to lowest we have:

(all terrain vehicle)72 mi/h >(go kart)67 mi/h >(scooter)12mi/h

Due to the all terrain vehicle has the highest velocity it is the faster vehicle.

Answer:

-4-9=-13

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

The shortest distance between planet Q and planet R is 1.25 × 10⁷ kilometers (12.5 million kilometers).

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

Answer:

2/3

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:

= (-7 - -1)/(-9)

(-1)^2 = 1:

= (-7 + 1)/(-9)

-7 + 1 = -6:

= (-6)/(-9)

The gcd of -6 and -9 is -3, so (-6)/(-9) = (-3×2)/(-3×3) = (-3)/(-3)×2/3 = 2/3:

Answer: = 2/3

number = x

2/3x + 18 = 23

The product, in scientific notation, can be rewritten as:

3.4196*10²⁵

We want to find the product between the two numbers:

(4.12*10⁹)*(8.3*10¹⁵)

To take it, we can rewrite the product as:

(4.12*8.3)*(10⁹*10¹⁵)

(34.196)*(10⁹⁺¹⁵)

(34.196)*10²⁴

Answer:

EQ = 47

Step-by-step explanation:

Since Q is midpoint, EQ = QF

or EQ = EF/2

5x + 2 = (9x + 13)/2

10x + 4 = 9x + 13

10x - 9x = 13 - 4

x = 9

EQ = 5x + 2 = 5(9) + 2 = 45 + 2 = 47

Using a linear function, it is found that:

A linear function is modeled by the following rule:

y = mx + b

In which:

From the table, we have that:

Hence, we have that when x = 0, y = 45, meaning that:

The y-intercept is of 45.

When x increases by 5, y decays by 8, hence the slope is given as follows:

m = -8/5 = -1.6.

Then the function is:

y = -1.6x + 45.

The x-intercept is found as follows:

-1.6x + 45 = 0

1.6x = 45

x = 45/1.6

x = 28.125.

The x-intercept is of 28.125.

By definition of vertical angles, the value of the variable x behind the geometric system is equal to 12. The measure of the labeled angle is 48°.

The image shows a geometric system generated by two non-parallel lines that intersect each other and consequently two pairs of vertical angles are therefore created. In geometry, two vertical angles are opposite to each other and have the same measure. Then, the following mathematical relationship is found:

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°

Velocity is the direction at which an item is moving and serves as a measure of the rate at which its location is changing as seen from a certain point of view and as measured by a specific unit of time (for example, 60 km/h northbound). In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a basic idea. A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined. Speed is the scalar absolute value (magnitude) of velocity; it is a coherent derived unit whose quantity is measured in metres per second (m/s or m/s1) in the SI (metric system).

An unreliable study can occur if the test administration is inconsistent

Consistency is the key to success in anything and it implies to the studies and surveys as well. If you want the results of the study to be reliable, then you must be consistent in test administration.

Inconsistency can lead to various issues like improper representation of the feedback which may alter the results. This can lead to various problems.

For example, test performed at certain time may have a different set of people and absence of periodic tests can accommodate feedback from irrelevant people.

Therefore, a proper set schedule must be followed for the tests with consistency.

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

Answer: Height = 5m

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

5 = h

The height of the triangle equals 5.

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

(t) = Ts + (T0 - Ts)e-kt, according to Newton's Law of Cooling.

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)

 ≈ 90.1

-------------------------------------------------------------------------------------

(b). When will the temperature of the coffee reach 85°?

     Find t so that T(t) = 85:   70 + 90e-0.15t = 85

90e-0.15t = 15

e-0.15t = 0.16666666

-0.15t = ln(0.166666666)      

t ≈ 12 minutes

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.
