Answer:
$62.85
Step-by-step explanation:
Given data
ratio= 10: 7: 5
Total ratio= 10+7+5= 22
Lisa= $20
Her proportion of the ratio = 7
Applying the part to all method
Let the total amount shared be x
7/22= 20/x
cross multiply
7x= 22*20
7x= 440
divide both sides by 7
x= 440/7
x= 62.85

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!

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.

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
Let alpha and beta be the radiant measures of two angles. Then sin left parenthesis 2 alpha plus 2 beta right parenthesis is equal to
Answer:
sin2αcos2β + cos2αsin2β
Step-by-step explanation:
Given that
sin(A+B) = sinA cos B + cos A sinB
According to the question;
sin(2α+2β) = sin2αcos2β + cos2αsin2β
where A = 2α and B = 2β

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

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

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

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

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:
[tex]V=\frac{1}{3}\cdot 6.1^2\pi \cdot 10.4,\\V=\boxed{405.04\:\mathrm{cm^3}}[/tex]
