Answer:
-12
Step-by-step explanation:
(3/4)m=-9
m=(-9/1)/(3/4)
m=(-9/1)(4/3)
m=-36/3
m=-12
Answer:
Step-by-step explanation:
given that two cards are drawn, without replacement, from a standard 52-card deck.
a) Both cards are red
Here there are 26 red cards and 52 total cards.
Probability = 
b) Both cards are the same color
i.e. either both are red or both are black
Hence probability = twice of part a
= 
c) The second card is a queen, given that the first card is an ace.
If first card is an ace remaining are 51 cards with 4 queens\
So prob = 4/51
Arranging units from smallest to largest:
pm, nm, um, mm, cm, dm, m, km.
Individual measurements in terms of 1 meter.
1 x 10^12 pm = 1 m
1 x 10^9 nm = 1m
1 x 10^6 um = 1m
1 x 10^3 mm = 1m
1 x 10^2 cm = 1m
1 x 10^1 dm = 1m
1m = 1m
1 x 10^-3 km <span> = 1m</span>
Answer:
The correct answer would be, No of bracelets the company must sell to break even would be 15
Step-by-step explanation:
Revenue is given by the function as:
R(x) = 20x
and Cost is given by the function as:
C(x) = 180 + 8x
Let the function P(x) represent the profit earned.
We know that Profit is equal to Revenue - Cost
i-e
Profit = Revenue - Cost
So,
P(x) = R(x) - C(x)
Now substituting the Revenue and cost values in the above equation.
P(x) = 20x - (180 + 8x)
P(x) = 20x -180 -8x
P(x) = 20x - 8x -180
P(x) = 12x - 180
Now if we want to find out the break even point, we would consider profit as Zero, 0. So substituting 0 in the above equation for Profit, we will get:
0 = 12x - 180
12x = 180
x = 180/12
x = 15
So the break even point will be 15 bracelets.
So you know if a and b are the numbers that a+b=36 and a-b=4 so you can solve one I solved the second equation for a a=4+b and plugging that a value into equations gives you 4+b+b=36
This simplified to 4+2b=36
2b=32
B=16 so you know one number is 16 and you can plug it in to find a a-16=4 so a=20
Therefore the two numbers are 16 and 20
