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)

Step-by-step explanation:
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.
Have a good day!

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

Simplify this math
|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

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.

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.

Find the measures of center and then type a numerical answer only (do not round).
Answer:
Mean: 13.5°
Median: 13.5°
Mode: 21°
Midrange: 13°
Step-by-step explanation:
Mean: Add all of the values together and divide by 8 (the number of values). This is also called average.
Median: The middle value when ranked lowest to highest. In this case there are an even number of values (8), so you have to use the average of the middle two, which are 12 and 15.
Mode: This is the most commonly appearing value, and in this case 21 is the only value that appears twice.
Midrange: To find this you add the highest and lowest values together and divide by two. In this case, those values are 5 and 21.
Select a value to tell how each pair of angles is related.

Please Help Me Will Give Brainliest
AYUDA
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.
Answer: the answer is a

Answer:
Congruent Sides- Rectangle, Rhombus, Square
Right Angles- Rectangle, Square
Both- Rectangle, Square
Step-by-step explanation:
Rectangle- Rectangles always have congruent sides and right angles
Rhombus- A rhombus is a parallelogram which makes it congruent but it does not have a right angle
Square- A square has both congruent sides and right angles every time as it is equal and straight on every side
Answer:
4 congruent sides- rhombus
4 right angles- rectangle
4 congruent and 4 rights - square
