You are playing a video game. For each diamond you collect, you earn 110 points. You also earn 80 bonus points by completing the level in less than 2 minutes. You need to earn more than 1620 points to continue on to the next level. Write and solve an inequality that represents the numbers d of diamonds you must collect in less than 2 minutes to advance to the next level.

Answers

Answer 1
Answer:

Answer:

110d=1620

Step-by-step explanation:

110d=1620

divide by 110 on each side

d=14.2727272727

so about 14 more diamonds need to be collected to move onto the next level

2) On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is t= d. How long will it take the airplane to travel 800 miles? Show your work 500

Answers

The equation for relation of time with distance travelled is,

t=(1)/(500)d

Substitute 800 for d in the equation to determine the time required for travelling 800 miles.

\begin{gathered} t=(1)/(500)\cdot800 \n =(8)/(5) \n =1.6 \end{gathered}

So airplane take 1.6 hours to travell 800 miles.

Answer: 1.6 hrs

What is 75 equal to?

A.) 7x 5
B. 5x5x5x5x5x5x5
C.7x7x7x7x7
D. 5 ‘7

Answers

Answer:

C

Step-by-step explanation:

you are multiplying 7 by its self 5 times

Final answer:

75 does not equal any of the options provided in the question. The calculations for each option yield numbers that are either larger or smaller than 75.

Explanation:

The number 75 can be best expressed as equal to 7x5 based on the options given in the question. Let's do a quick math check to confirm:

A) 7x5 = 35, which is not equal to 75.

B) 5x5x5x5x5x5x5 = 78125, which is much larger than 75.

C) 7x7x7x7x7 = 16807, which is also much larger than 75.

D) The last option 5 '7 does not make mathematical sense.

So, based on the calculations, none of the given options correctly express the number 75.

Which of the following statements best describes adjacent angles

Answers

The statement that best describes adjacent angles is that adjacent angles share a side.

What is a vertex ?

A vertex is where two non parallel lines meet.For example a triangle has 3 vertex.We can also say that vertex is a point where two non parallel lines meet to form an angle.

According to the given question the best description of adjacent angle is that they share a side.

We can say that adjacent angles are those angles which are placed next to each other.

Adjacent angle also share a common vertex but they do not overlap each other.

A ball is thrown downward from the top of a building with an initial speed of 25 m/s. It strikes the ground after 2.0 s. How high is the building, assuming negligible air resistance

Answers

Use one of the equations of motion under constant acceleration:-

s = ut + 0.5at^2   where s = distance, u - initial velocity, a = acceleration ( in this case it is gravity = 9.81 m s^-2)  and t = time.

here we have s = 25*2 + 0.5*9.81 * 2^2

= 69.62 meters answer

Answer: The height of the building is 69.6 m

Explanation:

To calculate the height of the building, we use second equation of motion:

s=ut+(1)/(2)at^2

where,

s = height of the building = ?

u = initial velocity of the ball = 25 m/s

a = acceleration due to gravity = 9.8m/s^2

t = time taken = 2.0 sec

Putting values in above equation, we get:

s=(25* 2.0)+(1)/(2)* 9.8* (2.0)^2\n\ns=69.6m

Hence, the height of the building is 69.6 m
