Answer:
[tex]-27x^2\\[/tex]
Step-by-step explanation:
(Assuming you can use a calculator)
[tex]\sqrt[3]{-729x^6} = \sqrt[3]{-1} * \sqrt[3]{729} * \sqrt[3]{x^6} \\\sqrt[3]{-1} =-1\\\sqrt[3]{729} = 27\\\sqrt[3]{x^6} = ((x^6)^{1/3}) = x^(6/3) = x^2\\\\hence\\\sqrt[3]{-729x^6} = -1*27*x^2 = -27x^2[/tex]

Suppose () = 46%; ( and ) = 10%; and ( or ) = 62% Find (Not ). Can this really be a probability? If not, explain why not.
Answer:
[tex]P(E) = 26 \%[/tex]
Step-by-step explanation:
Given
[tex]P(F) = 46\%[/tex]
[tex]P(E\ and\ F) = 10\%[/tex]
[tex]P(E\ or\ F) = 62\%[/tex]
Required
Find P(E)
In probability:
[tex]P(E\ and\ F) = P(E) + P(F) - p(E\ or\ F)[/tex]
Substitute the right values
[tex]10\% = P(E) + 46\% - 62\%[/tex]
[tex]10\% = P(E) -16 \%[/tex]
Collect Like Terms
[tex]P(E) = 10\% +16 \%[/tex]
[tex]P(E) = 26 \%[/tex]
It is a probability because all probabilities are within the range 0 to 100%
It cost $32 per day to rent a medium-sized car plus $0.25 for each mile driven over 150 miles the equation that represents this situation is y= 0.25x + 32 where y represents the total cost of renting a car and x represents the number of miles driven over 150 miles
Answer:
a) 0.25 stands for 25 cents per mile

Find the area of the triangle where C = 18.5°, a = 32.4 cm, b = 49.2 cm
HEHE HELP
Answer:
questions mistake look questions and apply the formula 1/2 B×H
if you have a triangle and don't know where are the base and the high use this formula
area = 0.5 × side × side × sin the angle between the 2 sides
area = o.5 (32.4) (49.2) (sin 18.5)
= 797.04 × sin 18.5

Pippa owns a snack bar.
She uses
of a kilogram of spread each day.
Spread costs £3.20 for a 1 kilogram tub and £6.15 for a 2 kilogram tub.
Pippa buys enough spread to last for 14 days.
What is the lowest price Pippa can buy this spread for?
Answer:
£43.05 (I believe, refer to step-by-step explanation.)
Step-by-step explanation:
Let's compare both of these tubs if we were to buy either of them for 14 days.
Starting with the 1 kilogram tub we need to do the calculation:
£3.20 × 14 = £44.80
(Type 3.2×14 into your calculator or write on paper this way to calculate.)
Now let's do the 2 kilogram tub.
£6.15 × 7 = £43.05
(Type 6.15×7 into your calculator or write on paper this way to calculate.)
The reason why I have put 7 instead of 14 is because it is 2 kilograms. Since Pippa uses 1 kilogram per day, you only need to buy 7. 2 × 7 = 14
So comparing either of these prices, buying 7 2-kilogram tubs is much cheaper compared to the 14 1-kilogram tubs.
A. Tomás collects sports cards. The number of baseball
cards he buys each week is proportional to the number
of football cards he buys.
B. Suppose Tomas buys a total of 30 seconds baseball and football cards in Week 5. How many of each would he have to buy to keep the same proportional relationship?
Week = 1 | 2 | 3 | 4
NOBC = 9 | 15 | ? | 6
NOFC = 6 | ? | 8 |
NOBC ( number of baseball cards)
NOFC ( Number Of football cards )
what is the slope intercept equation for the following line? 
(see image)
Answer:
y = x + 1
Step-by-step explanation:
You can immediately read off the y-intercept from the graph: (0, 1). The slope of this line is negative. Choosing two different points on this line leads to finding the slope of the line: (0, 1) and (2, -1) Going from the first point to the other, we see that x (the run) increases by 2 and y(the rise) decreases by 2. Thus, the slope is m = rise/run = 2/2 = 1.
The slope-intercept equation of this line is therefore y = x + 1.
Answer:
y=-1x+1
Step-by-step explanation:
To find the slope, we can use rise (vertical) over run (horizontal).
m=rise/run
We can see that from the first point to the second point, x increased by 2 and y decreased by 2.
The rise is -2 and the run is 2.
m=2/-2=-1.
The slope is -1.
Now let's find the y-intercept (the point where x=0, or where the line crosses the y-axis.)
This point is at (0,1), so b=1.
The y-intercept is 1.
This is the format for slope-intercept form: y=mx+b.
The slope-intercept equation is y=-1x+1.
A salesperson earns a commission of $378 for selling $2100 in merchandise find the commission rate write your answer as a percentag
Answer:
18%
Step-by-step explanation:
Given data
commission = $378
sales =$2100
Hence the percentage is given as
= 378/2100*100
=0.18*100
= 18%
Hence the percentage commission is 18%

Answer:
x = 13
Step-by-step explanation:
1. We can tell if the radical is in its simplest form if the square root term is a number that cannot be broken down to give a perfect square factor
what we are saying in this case is that if the number that is under the square root sign is one in which cannot be broken down to give a perfect square or that a perfect square is not its factor. Then it is in the simplest form
2. 512 = 2^(x-4)
512 = 2^9
2^9 = 2^(x-4)
since base is equal, we equate the powers
9 = x - 4
x = 9 + 4
x = 13
One of the altitudes of the parallelogram shown is StartRoot 22.5 EndRoot units. What is the length of the other altitude?
5 units
6 units
30 units
StartRoot 40 EndRoot units
Answer:
the length of the other altitude of the given parallelogram will be 6 units and option B is the correct choice.
The length of the other altitude in the parallelogram will be B. 6 units.
How to calculate the altitude?The equation to find the altitude in the parallelogram will be:
Altitude 1 × Vertical base = Altitude 2 × Horizontal base
✓22.5 × ✓40 = Altitude 2 × 5
30 = Altitude 2 × 5
Altitude 2 = 30/5
Altitude = 6
