**Answer 1**

Answer:

The answer is 792.

Step-by-step explanation:

I got the answer by first imagining how the 3d shape looks ike. Since one of the sqaure base length is 11 I found the base surface area by doing 11 times 11.My answer was 132. The since one of the slant length of the pyramid's triangle is 15, I did 11 times 15, my answer was 165. There are four triangles in the pyramid so I did 165 times 4, my answer was 660.

All the triangle surface area is 660 plus the sqaure surface are which is 132, that gave me my answer 792.

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

4/5 chance is the answer to that

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.
