Tim earns $150 each week plus 15.50 for each desk he assembles right and inequality to represent how many desks he needs to assemble to make 400 dollars in one week

Answers

Answer 1
Answer:

The answer is Tim must arrange at least 16 desks right to make $400 or x≥16

What is an inequality?

An inequality is an inequation separated by <,>≥,≤

Given here: Tim earns $150 each week plus 15.50 for each desk he assembles right, then let Tim assemble x desks right

Thus we have 150+15.50x=400

                                        x=16.12

Hence, Tim must arrange at least 16 desks right to make $400 or x≥16

Answers

Good evening ,

Answer :

$60

Step-by-step explanation:

   p − p×(15/100) = 51

⇔ p(1 - 15/100) = 51

⇔ p×[(100-15)/100] = 51

⇔ p×(85/100) = 51

⇔ 85×p = 100×51

⇔ p = 51×(100÷85) = 5 100÷85 = 60.

Henry is hanging flyers on front doors for his father's pizza business. He hung 130 flyers in 95 minutes. He still has 870 flyers to hang. His brothers, Nick and Adam, come to help. Nick hangs flyers 50% faster than Henry, and Adam hangs flyers 20% slower than Henry. Find the constant of proportionality for the flyer hanging rate of Henry, Nick, and Adam combined? (round to nearest tenth)

Answers

Given:
Henry: 130 flyers in 95 minutes.
Nick hangs flyers 50% faster than Henry
Adam hangs flyers 20% slower than Henry
Remaining flyers: 870

Henry's rate per minute = 130/95 = 1.37 flyers per minute

Nick: 1.37 * 1.50 = 2.055 or 2.06 flyers per minute
Adam: 1.37 * 0.80 = 1.095 or 1.10 flyers per minute

1.37 flyers + 2.06 flyers + 1.10 flyers = 4.53 flyers per minute.

870 flyers  ÷ 4.53 flyers per minute = 192 minutes

the constant proportionality for the flyer hanging of all three is 4.53 flyers per minute. They will finish hanging the remaining 870 flyer within 192 minutes.
the answer is 4.53 but you have to round to the nearest tenth so you get 4.5

Round 39892 to the nearest 1000

Answers

Answer:

39892 rounding to thousand is 40000.  

Step-by-step explanation:

Given : Number 39892.

To find : Round 39892 to the nearest 1000 ?

Solution :

Round to nearest thousand is

1) If the hundred place is less than 5 then the thousand place remain same and rest became zero.

2) If the hundred place is greater than or equal to 5 then the thousand place added by 1 same and rest became zero.

In number, 39892 the thousand place number is 9.

The hundred place is 8 greater than 5.

So, The thousand place added by 1 and rest became zero.

As 9 by 1 it shift to ten thousand place so 3 became 4.

39892 rounding to thousand is 40000.
your answer would be 1,000 I know it is werid but trust me
