Answer:
a. 0.85
b. [tex]f(t) =1000(0.85)^t[/tex]
c. $272.49
Step-by-step explanation:
Given that:
Initial investment made, 8 years ago = $1000
Depreciation value each year = 15%
To find:
a. Multiplier
b. Function [tex]f(t)[/tex] to describe the situation.
c. Worth of stock now.
Solution:
a. Depreciation of 15% means the value becomes (100 - 15) % = 85% or 0.85 of the actual value.
Therefore, the multiplier is 0.85.
b.
Every year the value becomes 0.85 times of the actual value.
If it continues for [tex]t[/tex] years, then the values will be:
[tex]f(t) =1000(0.85)^t[/tex]
c. Let us put [tex]t=8 \ years[/tex] to find the worth of stock now.
[tex]\Rightarrow f(8) =1000(0.85)^8\\\Rightarrow \bold{\$272.49}[/tex]
So, the answers are:
a. 0.85
b. [tex]f(t) =1000(0.85)^t[/tex]
c. $272.49

If the Weight of Candy Is proportional to the price and 12 ounces of candy is $3.00,dollars how much is 20 ounces of candy?
Answer:
$5.00
Step-by-step explanation:
if you divide $3.00 by 12 you get $0.25 which is what your paying per ounce so all you would have to do once you get how much your paying per ounce is multiply your per ounce number ($0.25) by your total amount of ounces (20) and you then get your answer $5.00. Hope this makes sense!

In the 2011 New York City Marathon, 29,867 men finished the race, and 16,928 women finished the race. Each finisher was given a t-shirt. About how many men's shirts were given away? About how many women's shirts were given away? Explain how you found your answers.
Answer:
About 30000 men
About 17000 women
Step-by-step explanation:
This question has to deal with approximation.
We have:
[tex]Men = 29867[/tex]
[tex]Women =16928[/tex]
To get the required answer, we have to approximate the given parameters.
For men, we have:
[tex]Men = 29867[/tex]
[tex]Men =30000[/tex] -- Approximated
For women, we have:
[tex]Women =16928[/tex]
[tex]Women = 17000[/tex] -- Approximated
This implies that about 30000 men and 17000 men received the t shirts

Let n be equal to 156% of 70. Which of the following proportions is true?
Answer:
156/100=n/70
Step-by-step explanation:
1.56/70=109.2
156/100=1.56
109.2/70=1.56
as far as im concerned 1.56 and 1.56 is equal lol
The true property is (156/100) = (n/70).
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that n is equal to 156% of 70
n=156% of 70
n=156% × 70
n= (156/100) × 70
(n/70) = (156/100)
Or, (156/100) = (n/70)
Hence, the true property is (156/100) = (n/70).

Answer:
x = 15p
-75
Explanation:
remove brackets:
4px + 4 = 64
solving for x --> 4px = 64 - 4 then--> 4px = 60
then diving both sides by 4p --> x = 60\4p --> x = 15p
now solving for x when p is -5
we will substitute the -5 in the equation we got --> x= 15 (-5)
which will give us --> x = -75

Which is the endpoint of a ray?
Opoint R
O points
Opoint T
O point U
Answer:
B-
point s
Step-by-step explanation:
I just did the quiz, this is the correct answer
Point S is the endpoint of the rays.
Option B is the correct answer.
What is a ray?In geometry, a ray is a straight line that starts from a specific point (called the endpoint) and extends infinitely in one direction.
A ray can be thought of as a part of a line that has one endpoint and continues indefinitely in one direction.
We have,
A ray is a line that starts from a specific point and extends infinitely in one direction.
The starting point of the ray is called the endpoint, and the other end of the ray extends indefinitely.
Therefore, a ray does not have an endpoint in the direction it extends, but only at its starting point.
From the figure,
The ray SR, SU, and ST have one common starting point.
i.e Point S.
Thus,
Point S is the endpoint of the rays.

Osvoldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 5 grams were from whole grains. Did Osvoldo meet his goal? Why?..
Answer:
Answer: Osvoldo did not meet his goal.
Step-by-step explanation:
Total carbohydrate ate by Osvoldo = 220 g
carbohydrate from grains = 55 g
Percentage of carbohydrate of grain is
\begin{gathered}=\dfrac{\text { carbohydrate taken from grains}}{\text {Total carbohydrate}} \times 100\\\\= \dfrac{55}{220} \times 100= 25 \%\end{gathered}
=
Total carbohydrate
carbohydrate taken from grains
×100
=
220
55
×100=25%
Goal of getting carbohydrate from grains = at least 30%
but he ate only 25% of carbohydrate
Hence, Osvoldo did not meet his goal as he ate less carbohydrate than his goal.
Juan read 300 pages in 5 days and Jose read 150 pages in 3 days are these reading rates equivalent
Answer:
No, they aren't equivalent.
Step-by-step explanation:
First divide 300 by 5 to figure out how many pages he read in each day.
That would be 60 pages each day.
Then, divide 150 by 3.
That would be 50.
Since 60 ≠ 50, the reading rates are not equivalent.

Which shows sets to which the number

Find the mode and the mean of the following set showing number of hours of operating life 25 flashlight batteries:20, 21, 19, 22 , 18 , 23 , 25 , 22 , 23 , 20 , 23 , 20 , 22 , 21 , 24 , 21, 22 , 23 , 19, 21, 22 , 22 , 24 , 26 , 22.
Answer:
mode: 22
mean: 21
Step-by-step explanation:
For mode, look for the number that occurs the most (22). I remember this because MODE kinda sounds like MOST. Remember that the mean is just another word for average. I remember this because I think its MEAN that they'd make another word for average, although the term average is way easier to remember. So, add all numbers (525) and divide them by 25.
525 divided by 25= 21
(it might be safe to double check my work)
The mean of the set showing number of hours of operating life 25 flashlight batteries is, 21.8
The mode of the set showing number of hours of operating life 25 flashlight batteries is, 22
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
The set showing number of hours of operating life 25 flashlight batteries is,
⇒ 20, 21, 19, 22 , 18 , 23 , 25 , 22 , 23 , 20 , 23 , 20 , 22 , 21 , 24 , 21, 22 , 23 , 19, 21, 22 , 22 , 24 , 26 , 22.
Now, We can arrange the numbers in ascending order as;
⇒ 18, 19, 19, 20, 20, 20, 21, 21, 21, 21, 22, 22, 22, 22, 22, 22, 22, 23, 23, 23, 23, 24, 24, 25, 26
Thus, The mean of the set is,
⇒ Mean = 18 + 19 + 19 + 20 + 20 + 20 + 21 + 21 + 21 + 21 + 22 + 22 + 22 + 22 + 22 + 22 + 22 + 23 + 23 + 23 + 23 + 24 + 24 + 25 + 26 / 25
⇒ Mean = 545 / 25
⇒ Mean = 21.8
And, The mode of the data set is the most often number in data set.
Hence, The mode of the set = 22
