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

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:

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: 1) Using the order of operations, you first have to multiply the amount of each item by it's price, and then add those values. So for Pablo, you would do (0.50 x 1) + (0.75 x 3) + (1.25 x 3) and solve within the parentheses to get .50+2.25+3.75=$6.50
2) For Laurie, use the same method from #1. First multiply and then add, like so: (0.5 x 2) + (1.25 x 3) + (0.75 x 3) ---> 1+3.75+2.25, which equals $7
3) Laurie > Pablo
$7.00 > $6.50
Step-by-step explanation:
The term order of operations is also known as PEMDAS

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.

Pentagon ABCDE is similar to pentagon PQRST. If the side length of pentagon ABCDE is 6 times the side length of pentagon PQRST, which
statement is true?
.A
The area of pentagon ABCDE is 6 times the area of pentagon PQRST
The area of pentagon ABCDE is 12 times the area of pentagon PQRST.
Ос.
The area of pentagon ABCDE is 36 times the area of pentagon PQRST.
D.
The area of pentagon ABCDE is 216 times the area of pentagon PQRST,
Answer: c
Step-by-step explanation:
The area of pentagon ABCDE is 36 times the area of pentagon PQRST. Therefore, the option C is the correct answer.
What is a pentagon?Any five-sided polygon or 5-gon is referred to as a pentagon. A basic pentagon's interior angles add up to 540°. A pentagon might be straightforward or self-intersecting.
We know the formula for the area of a pentagon, therefore, the area of the pentagon PQRST can be written as,
A= 1/4 ×√(5(5+25)×a²
Given that the side of the side length of pentagon ABCDE is 6 times the side length of pentagon PQRST, therefore, the area of the pentagon ABCDE can be written as,
Area of a ABCDE = 1/4 ×√(5(5+25)×(6a)²
= 1/4 ×√(5(5+25)×36a²
= 36A
Therefore, the option C is the correct answer.

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

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

17. a = 104
b = 175
19. [tex]\frac{144}{20} =\frac{252}{35}[/tex]

50 milligrams of medication
Step-by-step explanation:
16. [tex]\frac{r}{32} =\frac{5}{8} =\frac{30}{t}[/tex]
8 · 4 = 32
5 · 4 = 20
r = 20
5 · 6 = 30
8 · 6 = 48
t = 48
17. [tex]\frac{52}{a} =\frac{10}{20} =\frac{b}{350}[/tex]
Here is a different method.
[tex]\frac{10}{20} =\frac{1}{2}[/tex]
52 · 2 = 104
a = 104
350 ÷ 2 = 175
b = 175
22.
[tex]\frac{8}{3} :\frac{584}{y}[/tex]
8 · y = 3 · 584
8y = 1752
8y ÷ 8 = 1752 ÷ 8
y = 219
