Naomi and Hudson work at a dry cleaners ironing shirts. Naomi can iron 35 shirts per hour, and Hudson can iron 20 shirts per hour. Naomi and Hudson worked a combined 13 hours and ironed 395 shirts. Write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked. Define the variables that you use to write the system.
Answer:
Given that Naomi and Hudson work at a dry cleaners ironing shirts, and Naomi can iron 35 shirts per hour, while Hudson can iron 20 shirts per hour, knowing that Naomi and Hudson worked a combined 13 hours and ironed 395 shirts, to write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked, the following logical reasoning should be performed:
Naomi, working 13 hours, can iron up to 455 shirts (13 x 35), with which, every hour that Hudson has worked and she does not imply a decrease of 15 ironed shirts. Since 455 - 395 equals 60, and 60/20 equals 3, it is determined that Hudson worked 3 hours, while Naomi worked 10 hours.
Thus, the proposed inequality would be the following:
35Y + 20X = 395

If my diameter is 35.64 what is my circumference
Answer:
55.9548
Step-by-step explanation:
35.64 ÷ 2 = 17.82
17.82 × 3.14 = 55.9548
Answer: 111.97
Step-by-step explanation:
Circumference of a circle= 2πr
r= d/2
diameter= 35.64
Therefore circumference= 2*(3.14)*(35.64/2)
= 111.97

Name the slope and y-intercept of the graph of 3x - 2y = 18 A. B. 2 3 -6 6 C. -3.-9 D. 2 -9
Answer:
D. 3/2, -9
Step-by-step explanation:
First, rearrange the equation 3x - 2y = 18 into the slope-intercept form of y = mx + b:
3x - 2y = 18
2y = 3x - 18
y = 3x/2 - 9
from this, u can tell that the slope is 3/2 and the y-intercept is -9 (option D)

Which of the following represents the general equation for the geometric sequence?
-1, -2, -4, …
a n = 2 n - 1
a n = -1 · 2 n - 1
a n = 1 · 2 n + 1
a n = 1 · 2 n - 1
Answer:
-1,-2,-4
an = a1 * r^(n - 1)
a1 = first term = -1
r = common ratio = 2
so the equation would be : an = -1 * 2^(n - 1)
An antique desk,that once belonged to President Kennedy, appreciates in value by 15% per year. If Mark Zuckerberg were to purchase the desk for $50,000,how much would it be worth from now?
Answer:
$57500
Step-by-step explanation:
Given data
Initial cost of desk= $50,000
Percent increase=15%
=15/100*50,000
=0.15*50,000
=$7500
Hence the new price is 7500+50,000
=$57500

Yasmine is having a birthday party. Five people are sharing 34's of a pizza. What portion of the whole pizza will each person receive?
Answer:
3/20
Step-by-step explanation:
Given that :
Share for 5 persons = 3/4 of a whole pizza
Each person gets an equal size of the share :
Hence, share per person :
Portion of pizza / number of persons
3/4 ÷ 5
3/4 * 1/5
= (3*1) / (4*5)
= 3/20
