Shoes and hats are on sale. The expression 1/4(s + 24.80) can be used to determine the discount when you buy shoes with a retail price of s dollars and hats with a total retail price of $24.80. Write another expression that can be used to determine the discount.

Answers

Answer:

0.25s + 6.2

Step-by-step explanation:

Discount on sale expression : 1/4(s + 24.80)

Retail price of shoe = s

Retail price of hats = 24.80

From expression, we can conclude that there is a ; 1/4 = 0.25 = (0.25 * 100%) = 25% discount on each item ;

Hence, discount expression could be written as :

0.25s + 0.25(24.80)

0.25s + 6.2

x^3 - x^2 + 5x – 5 = 0

Answers

Answer:

The final solution is x = i√5, − i√5

Step-by-step explanation:

(x−1)(x2+5)=0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x−1=0

x^2+5=0

Set the first factor equal to 0 and solve.

x = 1

Set the next factor equal to 0 and solve.

The final solution is all the values that make (x−1)(x2+5)=0 true.

So, final solution is x = i√5, − i√5

Jane drew a point that was 3 units to the right of the y-axis and 5 units above x-axis what ordered pair for this location

Answers

Answer:

(3,5)

Step-by-step explanation:

If you imagine a grid in your head, moving 3 units to the right is the same as 3 on the x axis, and 5 units above the x axis is the same as 5 on the y axis. X goes before y in an ordered pair, so the answer would be (3,5). Hope this helps!!

The slope of the linear model is 1.5. What does this

mean in terms of the maximum noise level and the

number of people?

Answers

Answer:

Noise level increase by 1.5 per unit increase in number of persons

Step-by-step explanation:

The slope, m of a linear model is the value which represents the unit change in the dependent variable due to a unit chahe in the independent dependent.

The maximum noise in decibel is the dependent variable while the number of persons is the independent variable. Hence, the Coefficient of the independent vatiabkw is the slope and gives the rate of change in the dependent variable per unit Change in the independent variable.

If the probability that a person will die in the next year is
100000
probability that the person will not die in the next year?
A. 99%
B. 0.00365
C. 0.99635
D. 99635

Answers

The probability that the person will not die in the next year is 0.99635, the correct option is C.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

The probability that a person will die in the next year =100000

Now,

The probability that a person will die in the next year is given as 0.00001 (or 1/100000).

To find the probability that the person will not die in the next year, we can subtract the probability of dying from 1

Probability of not dying = 1 - Probability of dying

Probability of not dying = 1 - 0.00001

Probability of not dying = 0.99999

None of the options provided match this answer exactly, but the closest 0.99635.

Therefore, by the probability the answer will be 0.99635.

A city's population has increased 40% in the last 5 years and is now 53,782 people.

What was the population 5 years ago?

Answers

Given:

A city's population has increased 40% in the last 5 years and is now 53,782 people.

To find:

The population 5 years ago.

Solution:

Let x be the population 5 years ago.

A city's population has increased 40% in the last 5 years.

So, present population is

[tex]x+x\times \dfrac{40}{100}=x+0.4x=1.4x[/tex]

It is given that the present population is 53782.

[tex]1.4x=53782[/tex]

[tex]x=\dfrac{53782}{1.4}[/tex]

[tex]x=38415.7142857[/tex]

[tex]x\approx 38416[/tex]

Therefore, the population 5 years ago was about 38416.

Step-by-step explanation:

ten times the smallest of three consecutive integers is twenty two more than three times the sum of the integers. find the integers​

Answers

Answer:

31, 32 and 33

Step-by-step explanation:

Mark these consecutive integers as (n-1), n and (n+1)

(n-1) is the smallest of them

Now write the equation

10 * (n-1) = 3 * (n-1 + n + n+1) + 22

10n - 10 = 3 * (n + n + n) + 22

10n - 10 = 3 * 3n + 22

10n - 10 = 9n + 22

10n - 9n = 22 + 10

n = 32

Now find these three integers

n-1 = 32 - 1 = 31

n = 32

n+1 =32 + 1 =33

x would be the number of photos. to solve you subtract 5.95 from both sides which gets you 9.88=0.19x. so next you divide both sides by 0.19 which gets you 52 meaning she bought 52 photos. you check by inputting the variable 15.83= 5.95+0.19(52) and when you perform the math it gets you 15.83=15.83 meaning your answer is correct. hope this helped :)
