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

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.

I'm sorry, my explanation doesn't really make sense but I hope you kind of understood it.

Step-by-step explanation:

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

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.
