The sum of 2 times a number and 8 is 7

Answers

Answer:

The number is -1/2

Step-by-step explanation:

Let x be the number

2x+8 = 7

Subtract 8 from each side

2x+8-8 = 7-8

2x = -1

Divide each side by 2

2x/2 =-1/2

x = -1/2

The number is -1/2

Answer:

2x + 8 = 7

x = -1/2

Step-by-step explanation:

"a number" can be signified by a variable.

So 2 times a number would give you 2x

And 8 would mean to add 8.

Is 7 means the end result is 7.

So 2x + 8 = 7

x = -1/2

A field goal kicker makes 84% of the field goals he attempts he has attempted 50 field goals this season how many goals hs he made

Answers

Answer:

He has made 42 field goals this season

Step-by-step explanation:

To find x% of number y, multiply y by [tex]\frac{x}{100}[/tex] ⇒ [tex]\frac{x}{100}[/tex] × y

∵  A field goal kicker makes 84% of the field goals he attempts

→ That means he makes 84% of his total attempts

∵ He has attempted 50 field goals this season

→ That means his total attempts is 50 field goals

∴ He makes 84% of 50 field goals

∵ 84% = 84 ÷ 100 = 0.84

∴ He makes 0.84 of 50

∵ He makes = 0.84 × 50

∴ He makes = 42 field goals

∴ He has made 42 field goals this season

It is estimated that there are 828 motor vehicles in the US for every 1,000 people. If the number of motor vehicles in the US is 260 million, then what is its population to the nearest million?

Answers

Given :

It is estimated that there are 828 motor vehicles in the US for every 1,000 people.

To Find :

Number of motor vehicles in the US is 260 million, then what is its population to the nearest million.

Solution :

Ratio of car for 1000 people, [tex]R=\dfrac{828}{1000}=0.828[/tex].

Let, population is x million.

[tex]0.828 = \dfrac{260}{x}\\\\x =\dfrac{260}{0.828}\\\\x = 314 \ million[/tex]

Therefore, the population is 314 million.

Hence, this is the required solution.

At 1 the time, the hundreds of millions who watched this historic event likely thought it marked the beginningof a bold new kind of exploration. Perhaps they thought they would soon hear more messages from outer space. Maybe they envisioned that by the turn of the century someone would walk on the surface of Mars. Now, though, more than 40 years later, its robotsnot astronautswho are making most of the voyages beyond Earths atmosphere. Robotic space exploration does have some advantages. However, there are many reasons why we should make sending more people into space a priority.-Beyond the Program-The capabilities of the space probes and rovers we now use would have been the stuff of science fiction 2 just a few short decades ago. Like any other machines, though, they have one major weakness. Theycan do only what they are programmed to do. They cannot make a distinction between unusual and expected observations. They cannot reason. They cannot think. A human scientist who identified a curious specimen on Mars would likely concentrate on finding out everything possible about it. The unthinking robot would probably treat it as just another sample.-Efforts Yield Results-One of the arguments in favor of using robots to explore space is that machines can go places humans cannot. This may be true, but lets consider the other side. Maybe the reason astronauts are not able to go to these places yet is that we arent putting enough effort into figuring out how to meet their complex needs during prolonged space missions. Humans have proven time and again that they are able to solve problems that may have seemed impossible at first. There is no reason to assume that the challenge of sending people to Mars, Jupiter, or Neptune and getting them back home safely would be any different.-Costs and Benefits-Humans, as living things, have many needs that robots do not. Giving astronauts what they require to stay 4 healthy in space naturally makes these kinds of missions more expensive than ones that use robots. Its vital to weigh these increased costs against the benefits. If sending one human crew to Venus could advance our knowledge of the universe as much as three robotic space missions could, even a much higher cost would be justified.Keeping the Dream Alive It is said that the idea of traveling into space captures the imagination. For most, though, its not an image 5 of a small vehicle rolling across the surface of Mars that inspires awe and wonder. Its the notion thatone daypeople from Earth will explore distant worlds that are literally millions of miles away from our home planet.
