Answer:
(176, 193)
Step-by-step explanation:
Well you forgot to put in the choices, but:
The difference between the numbers is 17. Let's call the smaller number x and the bigger one y
(x + y) = 369
y = x + 17
(x + (x + 17)) = 369
2x + 17 = 369
2x = 352
x = 176
y = x + 17 = 193

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?
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.
A is the poin 3,5 and b is the point 0,k if the distance of ab is 5 units find the possible value of k
Answer:
K is either 9 or 1
Step-by-step explanation:
Sqrt((0 - 3)² + (k - 5)²) = 5
Square both sides
(0 - 3)² + (k - 5)² = 5²
(0 - 3)² + (k - 5)² = 25
-3² + (k - 5)² = 25
9 + (k-5)(k-5) = 25
9 + k² - 5k - 5k + 25 - 25 = 0
k² - 10k +9 = 0
k² - 9k - k + 9 = 0
k(k - 9) - 1(k - 9) = 0
k - 1 = 0 ; k = 1
k - 9 = 9; k = 1
K = 9 or k = 1
K is either 9 or 1

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?
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.

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.
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

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
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!!
