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.
~Lenvy~
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.

|x − (−12)| if x < −12
Thank you!
Answer:
-x-12
Step-by-step explanation:
Given:
[tex]\displaystyle \large{|x-(-12)| \quad (x < -12)}[/tex]
Simplify:
We know that negative times negative equals positive, therefore:
[tex]\displaystyle \large{|x+12| \quad (x < -12)}[/tex]
Modulus Property:
[tex]\displaystyle \large{|x+a| = \begin{cases} x+a \quad (x \geq -a) \\ -x-a \quad (x < -a) \end{cases}}[/tex]
Therefore, since given interval is x < -12:
[tex]\displaystyle \large{|x+12| \quad (x < -12) = -x-12}[/tex]
Hence, simplified expression is -x - 12
Answer:
-x-12

The middle square has an area of 1 square unit. What is the area of the entire rectangle in square units? Explain your reasoning.
Answer:
4
Step-by-step explanation:
I think its 4 because first, the 2 top tringles make a square, and 1+1=2. Then the 2 bottom ones make 2 more squares because one big triangle is equal to 1 square unit. So, its four.
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
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.
I'm sorry, my explanation doesn't really make sense but I hope you kind of understood it.

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.
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.

ASAP Will mark brainiest
Step-by-step explanation:
This is how we can find mean
Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set.
Now finding mean by this process

Answer:
6 (the last one)
Step-by-step explanation:
In order to isolate f you need to divide by 5/6
So, then you need to divide both sides by 5/6.
f=5(6/5) remember dividing is the same as multiplying by the reciprical.
f=6
Answer:
The answer is F = 6
Step-by-step explanation:
Solve for f
by simplifying both sides of the equation, then isolating the variable.

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.

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.

Q: Find the surface area to the nearest tenth←
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)
