Emily has 140 books. If Frank were to triple the number of books that he now owns, he would still have fewer than Emily has. If b = the number of books that Frank has, which mathematical sentence expresses the information above?

### Answers

Answer:

Step-by-step explanation:

Let b represent number of books that Frank has.

We have been given that Emily has 140 books.

Triple the number of books Frank would be three times b: .

If Frank were to triple the number of books that he now owns, he would still have fewer than Emily has.

This means is less than 140. We can represent this information in an inequality as:

Therefore, the inequality represents the given scenario.

B * 3 < 140

B being the number of books Frank owns. Because tripling the amount of books he owns is still less than the amount of book Emily owns, b*3 has to be less than 140

Marco draws a card and replaces it 10 times from a standard deck of 52 cards. He draws 8 red cards and 2 black cards. What is the theoretical probability that he will draw a red card on his 11th draw?

### Answers

Answer:

The probability would be 1/2 that he would draw a red color card.

Step-by-step explanation:

Marco draws a card from a standard deck of 52 cards and replace it 10 times. each time Marco draws 'with replacement' so it does not matter what cards were drawn previously so each draw result was independent.

In a standard deck of 52 cards there are 26 red cards.

p (drawing a red card on his 11th draw) = 26/52 = 1/2

therefore on his 11th draw 1/2 probability that he would draw a red color card

An interior angle of a regular polygon has a measure of 135°. What type of polygon is it? hexagon octagon nonagon decagon

### Answers

Answer: The correct option is (B) octagon.

Step-by-step explanation: Given that an interior angle of a regular polygon has a measure of 135°.

We are to select the type of the polygon from the given options.

We know that, if n represents the number of sides of a regular polygon and α be its exterior angle, then

Given that,

an interior angle of the regular polygon is 135°.

So, the measure of an exterior angle will be

Therefore, the number of sides of the regular polygon is

So, there are 8 sides of the polygon and hence it is an OCTAGON.

Thus, (B) is the correct option.

its a octagon. e2020 approved, you can trust me

Jim earns $1,600 per month after taxes. He is working on his budget and has the first three categories finished. Housing $576 Food $272 Transportation $320 Why will he have a problem with the rest of his budget? He is budgeting too much for transportation. He has used the highest recommended percentages to calculate the amounts for the three categories. He is budgeting too much for housing.

### Answers

Answer:

He has used the highest recommended percentages to calculate the amounts for the three categories.

Step-by-step explanation:

Monthly net earnings of Jim = $1600

He has budgeted Housing = $576

Food = $272

Transportation = $320

As no recommended percentage of food and housing is given so we can consider the ideal percentage. Ideally, a maximum of 30 to 35 percent should be spent on housing. And a maximum of 25 to 30% on food and transportation combined.

Here lets calculate 35% of housing, 0.35*1600= $560

And 30% of food and transportation , 0.30*1600=480

But Jim is spending $576 on housing and $592 on food and transportation. Comparing with the ideal maximum limit, we can see that Jim's budget has crossed the maximum limit.

So, the correct option is - He has used the highest recommended percentages to calculate the amounts for the three categories.

B.

He has used the highest recommended percentages to calculate the amounts for the three categories.

Tinh can row at a rate of 6 mph in still water. It takes her 2 hours to row upstream from a dock to a park. She then rows back to the dock, and it only takes 40 minutes. What is the speed of the river current?

### Answers

Answer: The speed of the river current = 3mph

Step-by-step explanation:

Let x be the speed of the river current.

Given: The speed of Tinh in still water = 6 mph

Let d be the distance from dock to park.

Now, speed in upstream = 6-x

Time taken in upstream = 2 hours

Distance covered upstream =....(1)

Speed in downstream = 6+x

Time taken in downstream = 40 minutes =hour= 2/3 hour

Distance covered downstream =.....(1)

From (1) and (2), we have

Hence, The speed of the river current = 3mph

I just got the right answer and its 3
