Can someone please help!! Due tonight!! I’ll give brainliest
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
Parentheses
Exponents
M/D - Multiplication/Division (whichever comes first in the equation)
A/S - Addition/Subtraction (whichever comes first)

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! ^^

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
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.
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

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]
What is the probability that a phone number generated using the digits 1, 2, 2, 4, 5, 5, 6, and 2 is the number 654-5222
Answer:
336 ways
Step-by-step explanation:
The digits are 1, 2, 2, 4, 5, 5, 6, and 2 that is total eight digits.
The number 654-5222 contains 7 digits.
So, we have find The number of permutations for choosing 7 digits from 8 digits given above.
This can be done in following ways
[tex]\frac{8!}{3!\times2!}[/tex] = [tex]\frac{40320}{6\times2}[/tex]
= 336 ways

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

Select the Pair(s) of ratios that form a proportion.
Answer:
Option 3
Step-by-step explanation:
If two ratios [tex]\frac{a}{b}[/tex] and [tex]\frac{c}{d}[/tex] are proportional,
[tex]\frac{a}{b}=\frac{c}{d}[/tex]
By applying this property for the given options,
Option 1
If the given ratios [tex]\frac{24}{31}[/tex] and [tex]\frac{20}{27}[/tex] are proportional.
[tex]\frac{24}{31}=\frac{20}{27}[/tex]
Which is false.
Therefore, ratios are not proportional.
Option 2
If the given ratios [tex]\frac{8}{9}[/tex] and [tex]\frac{24}{26}[/tex] are proportional,
[tex]\frac{8}{9}= \frac{24}{36}[/tex]
[tex]\frac{8}{9}= \frac{6}{9}[/tex]
False.
Therefore, given ratios are not proportional.
Option 3
If the given ratios [tex]\frac{16}{5}[/tex] and [tex]\frac{64}{20}[/tex] are proportional,
[tex]\frac{16}{5}=\frac{64}{20}[/tex]
[tex]\frac{16}{5}=\frac{16}{5}[/tex]
True.
Therefore, the given ratios are proportional.
Option 4
If the given ratios [tex]\frac{6}{4}[/tex] and [tex]\frac{15}{10}[/tex] are proportional,
[tex]\frac{6}{4}=\frac{15}{10}[/tex]
[tex]\frac{3}{2}= \frac{3}{2}[/tex]
True.
Therefore, given ratios are proportional.
Option 3 is the 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

Answer:
C. ≥
Step-by-step explanation:
The wording "at least" means the same as "greater than or equal to," both in English and in math. The latter is usually how we describe the symbol ≥.
So, when (something) is "at least" 18, the symbol to use to describe that is ...
(something) ≥ 18 . . . . . . matches choice C
