To the nearest square unit, what is the area of the regular octagon shown below?
Answer:
B. 1395 square units.
Step-by-step explanation:
We have been given an octagon. We are asked to find the area of the given regular octagon.
[tex]\text{Area of octagon}=\frac{a\cdot p}{2}[/tex], where,
a = Apothem,
p = Perimeter.
Let us find apothem of octagon by multiplying 17 by 8.

Plz explain me in simplest way. After X2 +17x-60=0 , I couldn't understand.
Answer:
see explanation
Step-by-step explanation:
Given
x² + 17x - 60 = 0
To factor the quadratic
Consider the factors of the constant term (- 60) which sum to give the coefficient of the x- term (+ 17)
The factors are + 20 and - 3, since
product = + 20 × - 3 = - 60 and sum = + 20 - 3 = + 17, thus
x² + 17x - 60 = (x + 20)(x - 3) = 0
Equate each factor to zero and solve for x
x + 20 = 0 ⇒ x = - 20
x - 3 = 0 ⇒ x = 3
Greta jumps up 2 feet into the air. Her potential energy is 60 Joules. Her kinetic energy is 40 Joules. What is the total mechanical energy?
A. 1,200 Joules
B. 800 Joules
C. 100 Joules
D. 200 Joules
The mechanical energy will be 100 Joules
Step-by-step explanation:Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.
So
Mechanical energy = 60J + 40J
Mechanical energy = 100 Joules
Answer:
The correct answer option is C. 100 Joules.
Step-by-step explanation:
We are given that Greta jumps up 2 feet into the air. Her potential energy is 60 Joules while her kinetic energy is 40 Joules.
We are to calculate her total mechanical energy which will be the sum of her potential energy and her kinetic energy.
So we simply need to add the two given values of the energies.
Total mechanical energy = 60 + 40 = 100 Joules

The scores of eighth-grade students in a math test are normally distributed with a mean of 57.5 and a standard deviation of 6.5. From this data, we can conclude that 68% of the students received scores between
Answer:
51 and 64
Step-by-step explanation:
The Empirical Rule states that 68% of normally distributed data lies within one standard deviation of the mean.
Hence, if the mean is 57.5, one standard dev. above that is 57.5+6.5, or 64, and one standard dev. below the mean is 57.5-6.5 = 51.
Thus,
we can conclude that 68% of the students received scores between 51 and 64.
Final answer:
Approximately 68% of the eighth-grade students received scores between 51 and 64.
Explanation:
In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean. So, in this case, 68% of the eighth-grade students received scores between the mean of 57.5 minus one standard deviation of 6.5 and the mean plus one standard deviation.
Calculating the range:
57.5 - 6.5 = 5157.5 + 6.5 = 64Therefore, we can conclude that approximately 68% of the students received scores between 51 and 64.

A cylindrical tree trunk is 17 yards tall from the ground to the first tree branch, and it measures 5 yards around. To the nearest cubic yard, what is the volume of this section of the tree trunk? Use 3.14 for pi.
a 334 cubic yards
b 78 cubic yards
c 1335 cubic yards
d 34 cubic yards
Answer:
c: 1,335 yd³
Step-by-step explanation:
The formula for volume of a cylinder is V = πr²h where r is the radius of the base circle, and h is the height of the cylinder
We are given r = 5, and h = 17. Plug them in and solve for V...
V = π(5²)(17)
V = π(25)(17)
V = 425π
V = 425(3.14) = 1,334.5 yd³,
so 1,335 yd³ rounded to the nearest cubic yard

Lake Snider High School surveyed its student population about if they prefer pizza or sushi. The students who prefer pizza represent twenty-seven fewer students than five times the number of students who prefer sushi. If 1,528 students prefer pizza, how many students prefer sushi?
Answer:
311 students
Step-by-step explanation:
Let s represent the number who prefer sushi
Let p represent the number who prefer pizza
Five times the number who prefer sushi = 5s
27 fewer than (5s) = 5s - 27
P = 5s - 27
1,528 = 5s - 27
1,555 = 5s (add 27 to both sides)
311 = s (divide both sides by 5)
311 students prefer sushi to pizza.
Given that Lake Snider High School surveyed its student population about if they prefer pizza or sushi, and the students who prefer pizza represent twenty-seven fewer students than five times the number of students who prefer sushi, if 1,528 students prefer pizza, to determine how many students prefer sushi the following calculation must be performed:
Sushi = (27 + 1528) / 5 Sushi = 1555/5 Sushi = 311
Therefore, 311 students prefer sushi to pizza.

#1 Marita uses the pan for corn bread. There is 3/4 inch of space left at the top of the pan when her corn bread is done baking. What is the volume of the corn bread Marita made?
#2 Marita wants to cut the corn bread in 1 1/2 inch squares. Can she do it? Explain.
Answer:
#1) 108.375 cubic inches
Step-by-step explanation:
For a pan of dimensions 8.5 in x 8.5 in, with height 2.25 in:
If cornbread fills to .75 in from the top, the height of cornbread is 2.25-.75 = 1.5 in
Volume = length*width*height (for rectangular prisms)
So Volume of corn bread = 1.5*8.5^2 = 108.375 cubic inches
For the second part, it is a poorly worded question. Squares are two dimensional, so it realistically cannot be cut into squares. If the question means cubes, the answer is yes to a certain extent. Since the height is exactly 1.5 in, and the pan is 8.5 in x 8.5 in, Marita can cut the cornbread into squares, but she cannot cut all of it into squares since 8.5/1.5 is not a whole number.
The temperature in a city was recorded over a ten-hour period. The graph below shows the relationship between the temperature and the number of hours.
Which statement best interprets information provided by the graph?
A. The temperature in the city increased for some time and decreased for some time.
B. The temperature remained constant for a while.
C. The temperature in the city increased throughout the period.
D. The temperature in the city increased at a constant rate for the entire time.
Answer:
A
Step-by-step explanation:
From the graph, we can see that the temperature increased initially, then started to decrease. All of these NOT in a constant rate, though.
Roughly, the temperature was increasing from start till around 5.5 hours. Then on the temperature decreased.
So we can eliminate B, C, and D. That leaves us with correct answer as A.

Suze wants to make 5 pies for a party. She needs 1 1/2 cup of confectioners sugar for each pie. She has two bags of confectioners sugars in her pantry. One bad has 3 1/4 cups remaining and the other bag has 6 1/8 cups remaining. How many cups of confectioners sugar Suze have left after she prepares her pies?
Answer:
1 7/8 cups leftover
Step-by-step explanation:
The total amt. of sugar Suze needs is 5(1 1/2 cups) = 15/2 cups, or 7.5 cups.
Combining the 3 1/4 and 6 1/8 cups of sugar remaining in the bag results in 3 2/8 + 6 1/8 cups, or 9 3/8 cups total. She needs only 7.5 cups of this sugar.
Thus, she has leftover the following amount: 9 3/8 - 7 4/8 cups, which
simplifies to 1 7/8 cups
Total C.Sugar
3 1/4+6 1/8
=13/4 + 49/8
=26/8 + 49/8
=75/8 cups
Used C.Sugar
1 1/2 × 5
= 3/2 × 5
= 15/2 cups
Remaining C.Sugar
75/8 - 15/2
=75/8 - 60/8
=15/8
=1 7/8 cups
Answer
1 7/8 cups remaining

If f (x)=x2and g(x)=c+6find g(f(0)
Answer:
6
Step-by-step explanation:
f (x)=x^2and g(x)=x+6 (I will assume you meant x not c)
The first step if to find f(0)
f(0) = 0^2 = 0
Now we find g(f(0))= g(0)
g(0) = 0+6 = 6
g(f(0) =6
If you meant c
Then g(f(0) = c+6

Jen slices a cone with a height of 10 centimeters and a radius of 4 centimeters using a plane that is perpendicular to the base and that passes through the vertex of the cone. What is the area of the cross-section in square centimeters?
Answer: [tex]40cm^2[/tex]
Step-by-step explanation:
A cross-section is the shape that results of the intersection of a plane with an abject.
When the cone is sliced by a plane perpendicular to the base and passes through the vertex, the cross-section obtained is a triangle.
The area of the triangle can be calculated with the formula:
[tex]A=\frac{b*h}{2}[/tex]
Where the base of the triangle is b and its height is h.
The base of the triangle is the diameter of the cone. Knowing the radius, the diameter is:
[tex]diameter=2*radius\\diameter=2*4cm\\diameter=8cm[/tex]
Then:
[tex]b=8cm[/tex]
The height ot this triangle is the height of the cone:
[tex]h=10cm[/tex]
So, by substituting into the formula you get the area of the cross-section in square centimeters:
[tex]A=\frac{(8cm)(10cm)}{2})=40cm^2[/tex]
