Ivan says that the shape at the right is n octagon. Do you agree or disagree? Explain
Answer:
Disagree
Step-by-step explanation:
An octagon has eight sides while the shape on the right has nine sides.
Answer:
No
Step-by-step explanation:
The shape shown in the picture has 9 sides(you can count) and therefore is not an octagon because octagons only have 8 sides.

x²+36=117
x²=81
x=9
Answer:
3[tex]\sqrt{17}[/tex] or 12.37 cm
Step-by-step explanation:
use the Pythagorean Theorem:
6² + [tex]\sqrt{117}[/tex]² = x²
36 + 117 = x²
x² = 153
x = [tex]\sqrt{153}[/tex] which is [tex]\sqrt{9}[/tex][tex]\sqrt{17}[/tex] or 3[tex]\sqrt{17}[/tex]
in decimal form, 'x' is approx 12.37
I need help with this!
Answer:
4.25
Step-by-step explanation:
Since this is a parallelogram, the parallel sides have the same value.
And since the perimeter of a parallelogram is all of the sides combined, this means
WR + RJ + JS + WS, or
5x + 5x + 3x + 2 + 3x +2 = 16x + 4
The perimeter is 16, so
16x + 4 = 16
16x = 12
x = 0.75
Substitute into 3x + 2, or WS.
2.25 + 2 = WS
WS = 4.25
Step-by-step explanation:
perimeter of parallelogram =16
2(WR+RJ)=162(5x+3x+2)=1610x+6x+4=1616x=16-4x=12/16x=3/4so value of WS=3x+2

Answer:
[tex]x\approx 24.0,\\y\approx 46.4[/tex]
Step-by-step explanation:
Let the height of the largest triangle marked be [tex]h[/tex]. We can set up the following equation:
[tex]\sin 30^{\circ}=\frac{h}{34},\\h=34 \sin 30^{\circ}=17[/tex] (if you're unfamiliar with trig, this is likely introduced to you as 30-60-90 triangle rules)
This height is also a leg of a 45-45-90 triangle, as marked in the diagram. From the isosceles-base-theorem, the other leg of this triangle must also be equal to [tex]h[/tex]. Therefore, we can use the Pythagorean theorem to solve for [tex]x[/tex]:
[tex]17^2+17^2=x^2\\x^2=\sqrt{17^2\cdot 2},\\x=17\sqrt{2}\approx \boxed{24.0}[/tex] (you can also use trig or 45-45-90 triangle rules which are derived from the Pythagorean theorem)
Segment [tex]y[/tex] consists of two shorter segments, a left segment and a right segment. We've already found that the left segment is equal to 17. To find the right segment we can use trig, the Pythagorean theorem, or 30-60-90 triangle rules (derived from the Pythagorean theorem):
Using Pythagorean Theorem:
[tex]y_{right}=\sqrt{34^2-17^2}\approx \boxed{29.4}[/tex]
Therefore, we have:
[tex]y=17+29.4=\boxed{46.4}[/tex]

Finding volume for geometry using 3.14.
Answer:
[tex]V=405.04\:\mathrm{cm^3}[/tex]
Step-by-step explanation:
The volume of a cone is given by [tex]V=\frac{1}{3}\cdot r^2\pi\cdot h[/tex] (the area of the base multiplied by the height divided by 3).
In the given cone, we have [tex]r=6.1\:\text{cm}[/tex] and [tex]h=10.4\:\text{cm}[/tex]. Substituting in these values, we get:
[tex]V=\frac{1}{3}\cdot 6.1^2\pi \cdot 10.4,\\V=\boxed{405.04\:\mathrm{cm^3}}[/tex]

Step-by-step explanation:
Attendance at state park throughout the year is found to be periodic and can be modeled by a sine function. The attendance ranges from a low approximately 1,00,000 visitors in september to a high of approximately 2,00,000 visitors in march. If t is the month number, where t=1 is january, and N(t)is the attendance, in millions, of visitors, which of the functions can be used to model this behavior A: N(t)=0.5sin(π/6 t)+1.5 B: N(t)=1sin(π/6 t)-1 C: N(t)=0.5sin(2πt)+1.5 D: N(t)=1.5sin(π/6 t)+0.5
Answer:
A. N(t) = 0.5·sin((π/6)·t) + 1.5
Step-by-step explanation:
The given parameters are;
The model of the periodic function = Sine function
The low of the attendance = 1,000,000
The month of the low in attendance = September
The high in attendance = 2,000,000
The month number = t,
The month of January is represented by, t = 1
N(t) = The attendance in millions of visitors
The generic sine function which is given as y = a·sin(b·x + c) + d, ranges from -1 to 1
Period = 12 = 2·π/b
∴ b = 2·π/12 = π/6
c = 0
a = The amplitude = (The maximum - The minimum)/2 = (2,000,000 - 1,000,000)/2 = 500,000
Therefore, a = 0.5×1,000,000 = 0.5·N(t)
Therefore, given that the minimum, [tex]N(t)_{min}[/tex] = 1, we have;
For sin(b·x + c) = -1, a·sin(b·x + c) = -0.5, for the minimum of 1,000,000 = 1 × 1,000,000, we have;
a·sin(b·x + c) + d = 1
∴ -0.5 + d = 1
d = 1.5
Therefore, we have;
N(t) = 0.5·sin((π/6)·t) + 1.5
Answer:
N(t) = 0.5sin((π/6)t) + 1.5

Answer:
V - 1099.55742876
SA - 769.690200129
Step-by-step explanation:
The volume of a cone is denoted by the formula:
V = 1/3 * h * pi * r^2
We can substitute in the values we are given:
V = 1/3 * 10.5 * pi * 10^2
V = 3.5 * 100 * pi
V = 350pi
This is about: 1099.55742876
The formula for the surface area of a cone is:
SA = pi * r^2 + pi * r * s
We can substitute what we have:
SA = pi * 10^2 + pi * 10 * 14.5
SA = 100 pi + 145 pi
SA = 245 pi
This is about: 769.690200129
in 2decimal places 39.98015
Answer:
39.98
Explanation:
39.98015
0 < 5, so 2nd decimal stays at 8
Answer:39.98
Step-by-step explanation:
Hey! I’m not exactly sure what you’re asking, but if the question is how to write that number in only two decimal places, it would be 39.98. We would round it up or down in the hundredths place because that is the second decimal place. Since the number behind the 8 is 0, we can’t round up or down so we would just leave it how it is and cut off the rest.
Hope this helped! :D
Sorry it I didn’t answer what you were asking! You can comment and I will answer any further questions!

A population of 12,000 fish has a growth rate of 4% each year. Write a model for the situation. How many years will it take of the population to reach 20,000
Answer:
13years
Step-by-step explanation:
Using the formula for calculating the compound interest expressed as;
A =P(1+r)^n
P = 12000
rate r = 4% = 0.04
Amount after 4 years A = 20,000
Substitute into the formula and solve for p
20,000 = 12,000(1+0.04)^t
20,000/12000 = (1.04)^t
1.67 = (1.04)^t
Take the ln of both side
ln1.67 = ln(1.04)^t
ln1.67 = t ln 1.04
t = ln1.67/ln1.04
t = 0.5108/0.0392
t = 13.03
hence it will take approximately 13years to reach 20,000
What value of x makes the equation x+ 38 = 72 true?
Answer:
x = 34
Step-by-step explanation:
Given
x + 38 = 72 ( subtract 38 from both sides )
x = 34
Answer:
X=34
Step-by-step explanation:
Well, what you can do is bring the 38 to the other side and make it negative so you can subtract 38 with the 72. The 72-38 is= 34 and so x= 34
x+38=72
x=72-38
x=34
Hope this helps! ^^

Charles runs a catering service for large parties. He needs 37 heads of lettuce for salad to feed 100 guests. Which of the following proportions could he use to determine the number of heads of lettuce, x, he would need for 275 guests?
Answer:
Step-by-step explanation:
Answer:
100/275=x/37
Step-by-step explanation:
37 heads for 100 guests that means the ratio is 37/100
To calculate how many is needed for 275 guests we should to multiply 275 by 37 and divide it by 100
And the expression for it is 100/275 = x/37

Step-by-step explanation:
When Vlad moved into his home a few years ago, there was a young oak tree in his backyard. He measured it once a year and found that it grew by 26 centimeters each year. 4.5 years after he moved into the house, the tree was 292 centimeters tall.
Answer:
175 cm
7 years
Step-by-step explanation:
Here is the complete question
When Vlad moved to his new home a few years ago, there was a young oak tree in his backyard.
He measured it once a year and found that it grew by 26 centimeters each year. 4.5 years after he moved into the house, the tree was 292 centimeters tall.
1. How tall was the tree when Vlad moved into the house?
2. How many years passed from the time Vlad moved in until the tree was 357 centimeters tall?
The formula for calculating future value:
FV = P + (r x n)
FV = Future height of the tree
P = Present height of the tree
R = growth rate
N = number of years
292 = p + (26 x 4.5)
292 = p + 117
p = 292 - 117
p = 175 cm
b. 357 = 175 + (26 x n)
375 - 175 = 26n
182 = 26n
n = 182 / 26 = 7 years
