Answer:
Natalie saved 16%
Step-by-step explanation:
Natalie saved 16% because 20 divided by 125 is 0.16
When we find percentages our goal is to get something like 0.24 which would mean 24% or 0.14 or 14% in this case it is perfect because we immediately see 0.16 or 16% leaving us with our answer, Natalie got 16% off her new phone.
Answer:
16%
Step-by-step explanation:
so that is the original number subtracted by a percentage, but that percentage is then multiplied by 125
125-(x/100)125=125-20
x=16

Question:
Carlos mixed [tex]\dfrac4{15}\text{ L}[/tex] of chocolate syrup with [tex]\dfrac12\text{ L}[/tex] of milk. Determine a reasonable estimate of the total amount of liquid Carlos mixed
Answer:
0.8 liters of liquid
Step-by-step explanation:
Given
[tex]Chocolate:= \dfrac4{15}\text{ L}[/tex]
[tex]Milk:= \dfrac12\text{ L}[/tex]
Required
An estimate of the total liquid
First, we get the actual total liquid.
[tex]Total = Chocolate + Milk[/tex]
[tex]Total =\dfrac4{15}\text{ L} + \dfrac12\text{ L}[/tex]
Take LCM
[tex]Total =\dfrac{8 + 15}{30}\text{ L}[/tex]
[tex]Total =\dfrac{23}{30}\text{ L}[/tex]
Express as decimal
[tex]Total ={0.7666}\text{ L}[/tex]
Estimate [Approximate]
[tex]Total ={0.8}\text{ L}[/tex]

[tex] \sf \cos^{2}(\theta) - \sin^{2}(\theta) =2-5 \cos(\theta) [/tex]
[tex]\text{note:explanation is a must}[/tex]
Answer:
θ = [tex]\frac{\pi }{3}[/tex] (60° )
Step-by-step explanation:
Using the identity
sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Given
cos²θ - sin²θ = 2 - 5cosθ
cos²θ - (1 - cos²θ) = 2 - 5cosθ
cos²θ - 1 + cos²θ = 2 - 5cosθ
2cos²θ - 1 = 2 - 5cosθ ( subtract 2 - 5cosθ from both sides )
2cos²θ + 5cosθ - 3 = 0 ← in standard form
(cosθ + 3)(2cosθ - 1) = 0 ← in factored form
Equate each factor to zero and solve for θ
cosθ + 3 = 0
cosθ = - 3 ← not possible as - 1 ≤ cosθ ≤ 1
2cosθ - 1 = 0
cosθ = [tex]\frac{1}{2}[/tex] , so
θ = [tex]cos^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = [tex]\frac{\pi }{3}[/tex] ( or 60° )

The diagram shows:
base = 13height = xRecall that the area of a parallelogram is equal to the base times height
area = base*height
We're told that the area is 117 square units, so that means 13x = 117.
Divide both sides by 13 to isolate x
13x = 117
13x/13 = 117/13
x = 9
The height of the parallelogram is 9
Note how:
area = base*height = 13*x = 13*9 = 117
which helps confirm we have the correct height value for x.

a lunch menu has 3 sandwhiches, 4 types of chips, and 5 types of drinks How many ways can a person order a meal
A person can order a meal in 60 different ways.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that a lunch menu has 3 sandwhiches, 4 types of chips, and 5 types of drinks.
Here we will use the combination of the data.
To answer this we just need to multiply 3 x 4 x 5.
3 x 4 x 5 = 60
Therefore, 60 ways can a person order a meal.

Brandon discovered that his daily routine of buying a slice of pizza and a soda at lunch was costing him more than 18,000$ per year. Choose the correct answer below. A. This statement does not make sense because this would mean that a slice of pizza and a soda costs him about 5$ a day. B. This statement makes sense because this would mean that a slice of pizza and a soda costs him about 5$ a day. C. This statement makes sense because this would mean that a slice of pizza and a soda costs him about 49$ a day. D. This statement does not make sense because this would mean that a slice of pizza and a soda costs him about 49 $ a day.
Answer:
This statement makes sense because this would mean that a slice of pizza and a soda costs him about $49 a day
Step-by-step explanation:
Given
The total spent on a slice of pizza and a soda is:
[tex]Cost > \$18000[/tex] per year
Required
Which of the options is true:
First, we calculate the daily amount spent on a slice of pizza and a soda.
Assume that the yearly cost is: $18000
The daily cost is:
[tex]Daily = \frac{\$18000}{365}[/tex]
[tex]Daily = \$49.32[/tex]
This means that he spends about $49 daily
