Answer:
965 parts would not be defective.
Step-by-step explanation:
So for every 400 parts, 14 are defective. That means 386 are not defective. 1000 is 2.5 times as many as 400. So multiply 386 by 2.5 to get your answer.
386/1 * 5/2
193/1 * 5/1
965/1
That means for every 1000 parts, 965 would not be defective. The proportion(s) would be 386:400/965:1000 here.

What value of n makes each statement true, pls include work
Answer:
1. n=2
2. n=12
3. n=2
Step-by-step explanation:
1
12xy³/4xⁿy=3y²/x
12x²y³=12y³xⁿ (cross multiplied)
x²=xⁿ (cancelled out (12y³))
2=n
2
(-3a/2b⁴)³=-27a³/8bⁿ
-27a³/8b¹²=-27a³/8bⁿ (cubed left side)
-216a³bⁿ =-216a³b¹² (cross multiplied)
bⁿ=b¹² (cancelled out (-216a³))
n=12
3
(xy⁶/x⁵yⁿ)²=y⁸/x⁸
x²y¹²/x¹⁰y²ⁿ=y⁸/x⁸ (squared left side)
x²y¹²/x¹⁰y²yⁿ=y⁸/x⁸
y¹⁰/x⁸yⁿ=y⁸/x⁸ (simplified)
y¹⁰x⁸=x⁸yⁿy⁸ (cross multiplied)
y²=yⁿ (cancelled out (x⁸), simplified)
n=2

What is the mass of 2.5 moles of carbon dioxide?
Answer:
110 grams
Step-by-step explanation:
CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).
So first finding the mass of 1 molecule of CO2 which is equals to
= mass of 1 carbon atom + masses of 2 oxygen atom, we get
= 12+(16*2)= 12+32= 44 a.m.u.
Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )
1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams
So our answer is 110 grams.

help I- AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Answer:
1/18
Step-by-step explanation:
Answer:
1/18
Step-by-step explanation:
When dividing a fraction with another number or fraction you always do the reciprocal of the second number and it turns into multiplication.
so it'll look like this: [tex]\frac{1}{9} *\frac{1}{2}[/tex]
then you just multiply straight across to get 1/18 because 1*1 is still 1 and 9*2 is 18

Answer:
for #1 it's 1, 4, 5, 6
for #2 it's both lines have the same slope
for #3 it's both lines have a different y-intercept
Step-by-step explanation:
#1 explanation: all of them have the y-intercept of -8
ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)
#2 explanation: both have a slope of (1/4)
#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different

How much solutions does this equation have?
2x+y=3
2y=-4x+6
pls answer,, show ur work, have a great day :)) !!
Answer:
All solutions or infinite.
Step-by-step explanation:
Turn 2y = -4x + 6 into standard form - divide by 2
Y = -2x + 3
2x + y = 3
Substitute the y equation in for y.
2x - 2x + 3 = 3
The x variables cancel out.
3 = 3
Which is true so it means all solutions.
Hope this helps.

Answer:
55
Step-by-step explanation:
Scott makes and sells bracelets. He spends $28 on supplies, and he sells
each bracelet for $6. Write an expression that represents his profit for
selling b bracelets.
Hi there,
Recall how each bracelet sells for 6 dollars.
Hence, the expression for selling b bracelets is 6b, where b is the number of bracelets sold for the price of 6 dollars.
Profit is the actual amount of money that is earned after you subtract expenses from the total sales.
For instance, if you make $100 from selling items, and you spent $25 on your supplies, then your profit is [tex]100-25=75[/tex].
In this case, you need to subtract the $28 spent on supplies from the amount of money that you have made, which is the expression 6b.
Hence, the expression for the profit is: [tex]6b-28[/tex]
Hope that helps.
