One out of every 9 light bulbs is defective.
What constant of proportionality relates defective bulbs to total bulbs?

Answers

Answer 1
The answer is very simple you can simply put it as 0.1
Answer 2

The constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

What is Constant Proportionality?

The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.

Given:

One out of every 9 light bulbs is defective.

Total bulbs = 9

So, Defective bulbs = 1

Thus, Constant of proportionality = Defective bulbs / Total bulbs.

Constant of proportionality = 1 / 9

Hence, the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

Answer:

90

Step-by-step explanation:

when  you multiply two negative integers they always equal positive so in this case its (-9) x (-10), you can just do 9x10 which gets u 90

Multiplying two positive integers always result in a positive integer.

Multiplying two negative integers always result in a negative integer.

Multiplying a positive or negative integer always result in a negative integer.

90
because negative x negative is always positive and 9x10 is 90

DUE TODAY (10/11/22) Need help on two questions!!

What term would you move using inverse operations to put this equation into standard form (Ax+By=C)

3x = 5 - 2y


5 by subtracting 5 to the other side

3x by dividing by 3 on both sides

-2y by adding 2y to other side


Natalie wanted to find the y intercept for the standard form of this equation. Here are her steps. Did Natalie make a mistake? If so, which one was her first? If not, indicate that as well.

Solve for the y intercept by substituting 0 for x.

2x + 4y = 20


Step 1: 2(0) + 4y = 20

Step 2: 0 + 4y = 20

Step 3: 4*4y = 20 * 4

Step 4: y = 80


A: Step 1

B: Step 2

C: Step 3

D: Step 4

E: Natalie made no mistakes

Answers

First problem you add 2 y second problem is step 3
#1) -2y by adding 2y to other side

#2) C: Step 3

Explanation:

#1) 5 is the only number without a variable, so isolating it would make the standard form true.

#2) Opposite of multiplication is division, so rather than multiplying 4 to both sides, Natalie should've divided.

A store sells a package of 25 trading cards for​ $5.25. What is the unit price per​ card?

Answers

The cost of one trading card obtained using the principle of proportionality is $0.21


Given the Parameters:

25 trading cards = $5.25


Let the Cost of one trading card = b


We could set up a proportional system to calculate the Cost of one trading card as
follows :

25 cards = $5.25
1 card = b


Cross multiply:

25b = $5.25


Divide both sides by 25 to isolate b



25b/25 = 5.25 / 25
b= $0.21


Therefore, one trading card costs $0.21
The numerator is smaller than the denominator what you divide 5.25 by 25 so the unit price is going to be less than 1.

The unit price is $0.21

Step-by-step explanation:

25 cards = $5.25

5.25/25 = $0.21

Deshaun wants to buy a new MP3 player that sells for $800 . The sales tax rate is 6.7%. What is the total cost of the MP3 player with tax included?

Answers

Answer:

$853.6

Step-by-step explanation:

6.7%=.067

.067x800+53.6+800+ansewr

853.6

If you say “6.7% of $800”
that means you have to get 6.7% into number form: 6.7% = 0.067,
“of” means multiplication. so 0.067 x 800= 53.6
add the tax to the original price = 53.6 + 800= 853.6
