Marcos can seal 5 envelopes every minute. Jerry can seal 7 envelopes every minute. They both seal envelopes for 1 hour nonstop.

How many more envelopes does Jerry seal than Marcos? Show your work.

Answer:

Answers

Answer 1

Answer:

 120

Step-by-step explanation:

Since,

Marcos seal 5 envelopes every minutes

Jerry seal 7  envelopes every minutes

Both seal envelopes for 1 hour

Knowing that 1 hour = 60 minutes

Thus,

Marcos = 5 × 60 = 300

Jerry = 7 × 60 = 420

Now subtract

420 - 300 = 120

Hence, Jerry seal 120 more than Marcos.

Answer 2

Answer:

120 more envelopes

Step-by-step explanation:

Given the following:

⇒ Marcos can seal 5 envelopes every minute.

⇒  Jerry can seal 7 envelopes every minute.

⇒ They both seal envelopes for 1 hour nonstop.

Question to Answer:

How many more envelopes does Jerry seal more than Marcos?

Solution:

Note that: 1 Hour = 60 Minutes

Thus, we can multiply envelopes by 60 minutes

Marcos → 5 × 60 = 300

Jerry → 7 × 60 = 420

Now we have to subtract to see how many more envelopes does jerry seal more than marcos.

420 - 300 = 120

Base on the result, we can conclude that jerry seal 120 more than marcos.

Answer:

Option A is right

Step-by-step explanation:

In any data set, we find that the range is the difference between maximum and minimum.  The range cannot give full information about the variability of the data set.

Outliers are the ones which are either below Q1-1.5IQR or Q3+1.5IQR

Thus Inter quartile range, the difference between I quartile and III quartile gives a better idea about variability and also outlier.

Hence out of the four options given, we find that option B is the right one.

Option

A. The IQR is the best measure of variability because the distribution has an outlier.

Cheyenne is hosting a barbecue on the Fourth of July. She plans to cook 30 burgers and at most 16 hot dogs on the grill.
Let h represent the number of hot dogs Cheyenne might cook. Which inequality models the story?

A. h ≥ 16

B. h ≤ 16

C. h ≥ 30

D. h ≤ 30

Answers

Answer:

B

Step-by-step explanation:

this is because she is only making less than or equal to 16 hotdogs, which the sigh indicates in answer B

Answer:

B

Step-by-step explanation:

It will be letter B because when it says at most it would be equal to 16 or less than 16 so, therefore, it will be letter B. The answer will not be for the burgers because since it says she plans to cook 30 burgers and not at most or at least it would mean that the answer will be either A or B.

Use the Converse to the Pythagorean Theorem to determine if the triangle below is a right triangle.

State whether or not the triangle is a right triangle.

Answers

Answer:

  not a right triangle

Step-by-step explanation:

The side lengths do not meet the requirements of the Triangle Inequality. The given figure is not even a triangle.

_____

Additional comment

The triangle inequality requires the sum of the two short sides exceed the long side:

  3 + 9 > 12 . . . . not true

__

The converse of the Pythagorean theorem tells you that the triangle is a right triangle if the sum of the squares of the short sides is equal to the square of the long side: 3² +9² = 12² (not true). Here, that criterion is not met, so the triangle is not a right triangle.

how to solve and answer for 4 1/3 - 2 1/5 ?

Answers

Answer : 2 2/15


To begin you need to convert the fractions into something they both can go into. Sometimes it is easier to multiple the two denominator of the fractions, which in this case it is.
So, 3 times 5 is 15
This means your going to convert your fraction into 15th

1/3 is 5/15
This is because you need to times the bottom by 5 in order to get 15, so you need to do the same with the top.

1/5 is 3/15
This is because you need to times the bottom by 3 to get 15 so you do the same with the top

Next you just subtract the amounts separately
4-2 = 2
5/15 - 3/15 = 2/15

This means your answer is 2 2/15

Answer:

2 2/15 or if you want it in decimal form it's 2.133

how many brownies are there

Answer/Step-by-step explanation:

From the first attachment or we can also say:

https://brainly.com/question/27391854

Base on first attachment:

There are 12 people ⇒ Emily, Delvenal, 10 other friends that was suppose to come

Either :

cut the pan of brownies into the 12 pieces

cut the pan of brownies into 24 pieces

But from this second attachment we know that:

Out of the 10 friend that war suppose to come only 7 came.

Thus if they cut the pan of brownies into 12 pieces then

Emily and delvenal + 7 friend = 10 people

12 - 10 = 2

Hence, 2 pieces of brownies are left.

Thus, if they cut the pan of brownies into 24 pieces then

Emily and delvenal + 7 friend = 10 people

24 - 10 = 14

Hence, 14 pieces of brownies are left.

Q: Find the surface area to the nearest tenth←

Answers

Answer:

119.0 cm²

Step-by-step explanation:

What is surface area

It is the area of the outside part of anything. Surface area is also called total surface area.

As we can see from the pyramid, it has a square base. How do I know that it is a square base, is by seeing the dimensions of the base, which are 6.4 cm by 6.4 cm in this pyramid. And we already know from basic Geometry that a square has 4 equal sides. So we call it a square pyramid.

So to find the total surface area of this square pyramid, we need the area of the 4 triangular faces and the area of the square base.

So t.s.a of the pyramid = 4 × Area of each triangular face + Area of the square base.

So, total surface area = Area of square base + Area of the four triangular faces.

     total surface area = (length²) + (4 × [tex]\frac{1}{2}[/tex] × base × height)

     total surface area = (6.4 × 6.4) + (4 × [tex]\frac{1}{2}[/tex] × 6.4 × 6.1)

     total surface area = 40.96 + 78.08

     total surface area = 119.04 cm² ≈ 119.0 cm² (to the nearest tenth) (Answer)

119.0cm^2

So t.s.a of the pyramid = 4 × Area of each
triangular face + Area of the square base.
So, total surface area = Area of square base +
Area of the four triangular faces.
total surface area = (length?) + (4 × ;
× base × height)
total surface area = (6.4 x 6.4) + (4 x = x
6.4 x 6.1)
total surface area = 40.96 + 78.08
total surface area = 119.04 cm^2 ~ 119.0 cm^2

Modulus Property:

[tex]\displaystyle \large{|x+a| = \begin{cases} x+a \quad (x \geq -a) \\ -x-a \quad (x < -a) \end{cases}}[/tex]
