If the distance between Sydney and Goulburn is 200 km, find the average speed to
complete the journey in 2hr 30mins (hint: speed = distance/time).

Answers

Answer 1

Answer:

Average Speed to complete the journey = 80 km/h

Step-by-step explanation:

Given,

The distance between Sydney and Goulburn = 200 kilometer.

Time to complete the journey = 2 hour 30 minutes

Converting the time into minutes -

2 hour 30 minutes

= (2 x 60) minutes + 30 minutes

= 120 minutes + 30 minutes

= 150 minutes

We know, to determine average speed, we have to divide the distance by time.

Therefore, Speed = [tex]\frac{Distance}{Time}[/tex]

Speed = [tex]\frac{200 km}{150 minutes}[/tex]

Speed = 1.33 km/minutes

Speed = (1.33 km x 60) km/hour (To convert it to hour, we have to multiply by 60)

Average Speed per hour = 80 km/h

after using six mushrooms to boost their speed. marcus racer has travelled 650 feet. hiw far did marcus racer travel after using three mishrooms?​

Answers

Answer: 325 ft

Step-by-step explanation:

6 mushrooms = 650 ft

divide by 2 on both sides

3 mushrooms = 325 ft

5 mushrooms = 6-1 mushrooms

5 mushrooms = 650 - (boost distance for 1 mushroom)

1 mushroom = 650/6 = 108.3 repeating

so 5 mushrooms = 650 - 108.333333333 = 542.66666666

13b. C

Step-by-step explanation:

13a. The first ride costs $2.75 more than the second ride.  Each quarter mile after the first quarter mile costs $0.75, so the difference in distance is:

0.75 d = 2.75

d = 3.67

The difference is 3.67 quarter miles, or 0.92 miles.

13b. The total cost is the cost of the first quarter mile plus the cost of the rest of the quarter miles.

What is the measure of ∠XBC?

m∠XBC = m∠BAC + m∠BCA
3p – 6 = p + 4 + 84
3p – 6 = p + 88
2p – 6 = 88
2p = 94

Answers

Answer:

The diagram of the question is attached here.

The measure of [tex]\angle XBC=135\ (deg)[/tex]

Step-by-step explanation:

All the options given here will be used to find the numeric value of [tex]\angle XBC[/tex]

Here it is shown systematically.

Exterior angle theorem: Sum of two interior angles are equal to the measure of opposite exterior angle in a triangle.

To find [tex]\angle XBC[/tex]

[tex]m\angle XBC = m\angle BAC + m\angle BCA[/tex]

Plugging the values.

[tex]3p-6 = p + 4 + (84)[/tex]

[tex]3p-6 = p + 88[/tex]

Subtracting [tex]p[/tex] both sides.

[tex]2p-6 = 88[/tex]

[tex]2p = 94[/tex]

Dividing [tex]2[/tex] both sides.

[tex]p=\frac{94}{2}=47[/tex]

So plugging the value of [tex]p=47[/tex] in [tex]3p-6[/tex] we will get the measure of [tex]\angle XBC[/tex].

So [tex]\angle XBC=(3p-6)=3(47)-6=135\ (deg)[/tex]

The measure of [tex]\angle XBC[/tex] is [tex]135\ degrees[/tex].

Based on the information, the measure of Angle XBC is 278 - 4p degrees.

What's the measurements?

Given that Angle ACB is 84 degrees, Angle BAC is (p + 4) degrees, and Angle XBC is (3p - 6) degrees, you can plug in these values:

(p + 4) + 84 + (3p - 6) + Angle XBC = 360

Combine the like terms involving 'p':

4p + 82 + Angle XBC = 360

Subtract 82 from both sides:

4p + Angle XBC = 278

Now, isolate Angle XBC by subtracting 4p from both sides:

Angle XBC = 278 - 4p

So, the measure of Angle XBC is 278 - 4p degrees.

Sofia has $1.90 worth of nickels and dimes. She has a total of 25 nickels and dimes altogether. Write a system of equations that could be used to determine the number of nickels and the number of dimes that Sofia has. Define the variables that you use to write the system.

Answers

Answer:

The number of dimes does Sofia has is 13 , and The number of dimes does nickles does Sofia has is 12

Step-by-step explanation:

Given as :

The net worth of nickels and dimes = $ 1.90

The total number of nickles and dimes altogether = 25

Let The number of nickles that Sofia has = n

And The number of dimes that Sofia has = d

Now,

Since The value of 1 nickle = [tex]\frac{1}{20}[/tex] dollar

And The value of 1 dimes =  [tex]\frac{1}{10}[/tex] dollar

So, According to question

n + d = 25          ..........1

And  $ [tex]\frac{1}{20}[/tex] × n + $ [tex]\frac{1}{10}[/tex] × d = $ 1.90

Or, n + 2 d = 38        .....2

Solving Eq 1 and 2

∵  n + 2 d = 38

or, 25 - d + 2 d = 38

or, d = 38 - 25

∴ d = 13

So, The number of dimes she has = 13

And the number of nickles = n = 25 - 13

∴  n = 12

Hence The number of dimes does Sofia has is 13 , and The number of dimes does nickles does Sofia has is 12 Answer

How to solve : 16=2t + 0.25 t``squar​

Answers

Answer:

The solutions of the equation are t = 4(√5 + 1) or 4(√5 - 1).

Step-by-step explanation:

We have to solve the given quadratic equation of single variable t.

The equation is 16 = 2t + 0.25t²

⇒ 0.25t² + 2t - 16 = 0

⇒ 25t² + 200t - 1600 = 0 {Multiplying both sides with 100}

⇒ 25t² + 200t + 400 - 400 - 1600 = 0

(5t + 20)² - 2000 = 0

⇒ (5t + 20)² - (20√5)² = 0

⇒ (5t + 20 + 20√5)(5t + 20 - 20√5) = 0

So, (5t + 20 + 20√5) = 0 or, (5t + 20 - 20√5) = 0

(t + 4 + 4√5) = 0 or, (t + 4 - 4√5) = 0

t = - 4(1 + √5) or, t = 4(√5 - 1) (Answer)

A fireworks rocket is launched from a hill above a lake. The rocket will fall into the lake after exploding at its maximum height. The rocket's height above the surface of the lake is given by g(x)= -16x^2+64+80. What is the maximum height of the rocket?

A) 150 feet C) 120 feet

B) 80 feet D) 144 feet

Answers

Answer:

D

Step-by-step explanation:

At the maximum height, the value of the vertical velocity Vy equals zero. From the value of the equation, we can get the vertical velocity by its first differential.

Differentiating this, we get -32x + 64

We then equate this value to zero. This yield 32x = 64 and x = 2

We now plug the value of x back into the original expression for height.

-16(2)^2 + 64(2) + 80 = -64 + 128 + 80 = 144 feet

The average weight of a watermelon is 4.61 kg. The average weight of a coconut is 2.22 kg less than a watermelon. The total weight of an equal number of coconuts and watermelons is 140 kg. How many coconuts are there? ​

Answers

Since the average weight of a coconut is 2.22 kg less than a watermelon, its average weight is

[tex]4.61-2.22=2.39[/tex]Let n be the number of coconuts and watermelons. The total weight of n coconuts and n watermelons is

[tex]4.61n+2.39n = 7n[/tex]

If we want this total to be 140, we have

[tex]7n=140 \iff n=\dfrac{140}{7}=20[/tex]

So, you have 20 coconuts and 20 watermelons.

Final answer:

To find the number of coconuts, we can set up an equation using the given information. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon. By setting up the equation x(4.61 + 2.39) = 140 and solving for x, we find that there are 20 coconuts.

Explanation:

To solve this problem, we need to set up equations using the given information. Let's represent the number of coconuts as 'x'. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon, which means it is 4.61 - 2.22 = 2.39 kg. Since the number of coconuts and watermelons is equal, we can write the equation: x(4.61 + 2.39) = 140. Solving this equation, we get 7x = 140, which means x = 140/7 = 20.

Therefore, there are 20 coconuts.

Write the equation of the line that is parallel to y=-0.75x and that passes through the point (8,0)

Answers

Final answer:

The equation of the line that is parallel to y=-0.75x and passes through the point (8,0) is y = -0.75x + 6.

Explanation:

The equation of a line in the form y = mx + b represents a linear equation, where m is the slope of the line and b is the y-intercept. Since we are looking for a line parallel to y = -0.75x, we know that the new line will have the same slope. So, the equation of the new line is y = -0.75x + b. To find the value of b, we can substitute the coordinates of the point (8,0) into the equation and solve for b.

0 = -0.75(8) + b

0 = -6 + b

b = 6

Therefore, the equation of the line that is parallel to y = -0.75x and passes through the point (8,0) is y = -0.75x + 6.

In the other 50 houses, all the lights are changed to 60-watt bulbs. After two months, Dr. Jones measures the level of depression for the people living in the houses. Assuming that the study uses people from different age groups, participant age would be a(n) ________ variable in the experiment.a. extraneousb. dependentc. confoundingd. independent It became apparent to Watson and Crick after completion of their model that the DNA molecule could carry a vast amount of hereditary information. Which of the following characteristics of DNA is responsible for this?A) Sequence of basesB) Phosphate -sugar backbonesC) Complementary pairing of basesD) Side groups of nitrogenous basesE) Different five-carbon sugar Graph the line described by y 3 = -5/6(x + 3). Membership in an elite organization requires a test score in the upper 30% range. If the mean is equal to 115 and the standard deviation is equal to 12, find the lowest acceptable score that would enable a candidate to apply for membership.
