Elijah earns $18 a day working part time at a gas
station. Write an algebraic expression to represent the
amount of money she will earn in d days.
PLEASE HELP MEEEEEEREEEE
Answer:
[tex] - \frac{5}{6} [/tex]
Step-by-step explanation:
The first thing to do is solve for the root. A trick is to ignore the numerator and only focus on the denominator in the root. So it is a third root so you have to find out what multiplied by itself three times is 343. The correct answer for that is 7. So now we must introduce the numerator back, so it would be:
[tex] \frac{1}{7} [/tex]
I'll show the new expression below.
[tex] \frac{1}{6} - 7( \frac{1}{7} )[/tex]
Second order of business is to multiply the second half of the expression. Easy enough the 7 cancels out the 1/7. New expression below.
[tex] \frac{1}{6} - 1[/tex]
Now just solve for that.
[tex] - \frac{5}{6} [/tex]

What is the next term of the following sequence? 20, 10, 5, 2, 1/2 ...
A:3/4
B:1 1/2
C:1 1/4
Answer:
I'm thinking it's A...
==================================================
Explanation:
I'm assuming you meant to say 2 & 1/2 instead of 2,1/2
If so, then we cut that last term 2 & 1/2 in half
The whole part 2 cuts in half to 1
The fractional part 1/2 cuts in half to 1/4
2 & 1/2 cuts in half to 1 & 1/4 which leads to choice C
The reason why we cut in half is because the jump from 20 to 10 is "divide by 2", and the same applies from 10 to 5, and from 5 to 2 & 1/2.
This is 9thh grade math and I really need help sorry for the m
Let 'n' be the original number
Let 'a' be the digit in the ten's place of 'n'
Let 'b' be the digit in the one's place of 'n'
Then, n = 10a + b
We have,
a+b = 11 -------- (equation 1)
Let m be the number formed when the digits of n are reversed
Then, m = 10b + a
Given that, m = n + 27
=> 10b + a = (10a + b) + 27
=> 9b - 9a = 27
=> 9(b - a) = 27
=> b - a = 3 ----- (equation 2)
Adding equation 1 and 2, we get
2b = 14
=> b = 7
putting b = 7 in equation 1
a + 7 = 11
=> a = 4
Therefore original number is 10×4 + 7 i.e. 47
help me please for my final
Answer:
Equation of line l,
3x-4y=1/2
y=3/4x-1/2
we get,
slope of line l =3/4
Equation of line m,
x-5=2y
y=1/2-5/2
Hence slope of line m=1/2
Slope of line l is not equal to slope of line m. Hence the line are not parallel.
Slope of line l* slope of line m ,
(3/4)*(1/2) =3/8
Since the product of slope of line l and the slope of line m is not equal to -1, the lines are not perpendicular.
Hence the lines are neither perpendicular nor parallel..
Answer:
none are parallel

The scores on a test given to all juniors in a school district are normally distributed with a mean of 79 and a standard deviation of 7. Find the percent of juniors whose score is no more than 86. The percent of juniors whose score is 86 or below is %.
Answer:
p (x -<-89) = p( _x_-_75_ < _ 89_- __75__) = p (z <_ 2) = 0.9773= 97.73%

11. A landscaper is designing a rectangular garden, which will be 5.00 m
wide by 6.25 m long. She has enough crushed rock to cover an area
of 6.0 m² and wants to make a uniform border around the garden.
How wide should the border be, if she wants to use all the crushed
rock?
9514 1404 393
Answer:
25.5 cm
Step-by-step explanation:
If the walk is x meters wide, it adds 2x to the overall length and width. Then the area of the walkway is ...
(2x +5)(2x +6.25) -(5)(6.25) = 6
4x^2 +22.5x = 6 . . . . simplify left side
4x^2 +22.5x -6 = 0 . . . subtract 6 to put into standard form
Using the quadratic formula, the walkway width can be found to be ...
x = (-22.5 +√(22.5² -4(4)(-6)))/(2(4)) = (-22.5 +√602.25)/8
x ≈ 0.25510
The border width should be about 25.5 cm.
Which expression uses the greatest common factor and the distributive property to rewrite the sum 7 + 75
Answer:
[tex]75 + 45[/tex] [tex]= 15(3 + 5)[/tex]
Step-by-step explanation:
Given
[tex]75 + 45[/tex] -- Corrected
Required
Use the GCF to write it as a distributive property
First, we find the GCF of 75 and 45
[tex]45 = 3 * 3 * 5[/tex]
[tex]75 = 3 * 5 * 5[/tex]
The common factor is:
[tex]GCF = 3 * 5[/tex]
[tex]GCF = 15[/tex]
So, [tex]75 + 45[/tex] becomes
[tex]75 + 45[/tex] [tex]= 15 * 3 + 15 * 5[/tex]
Factorize
[tex]75 + 45[/tex] [tex]= 15(3 + 5)[/tex]
Hence, the sum has been rewritten as [tex]15(3 + 5)[/tex]

Daria pays x dollars for a pair of shoes. The tax on shoes is
6%. The expression representing her total cost is x + 0.06x.
Which expression is equivalent and why?
A. (0.06) because the cost of the shoes can be factored out.
OB. 1.6x because adding 6% to the cost of the shoes is the same as
multiplying the cost by 1.6.
O.
C. 1.06x because adding 6% to the cost of the shoes is the same as
multiplying the cost by 1.06.
D. 1.06x because adding $6 to the cost of the shoes is the same as
multiplying the cost by 1.06.

Determine if the equations are parallel, perpendicular or neither x-y=5 and x+y=-10
Answer: Perpendicular
Step-by-step explanation: x-y=5 —-> subtract x from both sides to give you y alone. -y= -x+5 —-> next step is to continue to get y alone so you have to divide both sides by -1. y=x-5 now the first one is done
x+y=-10 —-> solve to get y alone so subtract both sides by x making it y=-x-10 Meaning that the two lines are perpendicular to each other.
