Answer:
[tex]\frac{1}{15^{6}}[/tex]
Step-by-step explanation:
If you see a negative sign in the power, you will place the number and power over 1:
15^-6 = 1/(15^6)
[tex]\frac{1}{15^{6}}[/tex]
Simplify. Solve 15^6:
15^6 = 15 * 15 * 15 * 15 * 15 * 15 = 11,390,625
1/11,390,625 is your simplified answer.
However, note that you are solving for a positive exponent. Your answer will be:
[tex]\frac{1}{15^{6}}[/tex]
Jacob is a construction
worker who earns a yearly income given by the expression 2000x + 4000, where X is the number of hours
he works each week. Carlos works with Jacob and earns a yearly income given by the expression 3500x - 40000. A manager
predicts that if Carlos and jacob each work 35 hours, they will earn the same amount of money,
Answer:
The manager's prediction is false
Step-by-step explanation:
Given
Jacob: 2000x + 4000
Carlos: 3500x - 40000
Required
Determine if both expression will be the same if x = 35
To do this;
Equate both expressions and then solve for x
i.e.
[tex]2000x + 4000 = 3500x - 40000[/tex]
Collect Like Terms
[tex]2000x - 3500x = -4000 - 40000[/tex]
[tex]-1500x = -44000[/tex]
Divide both sides by -1500
[tex]\frac{-1500x}{-1500} = \frac{-44000}{-1500}[/tex]
[tex]x = \frac{-44000}{-1500}[/tex]
[tex]x - 29.3[/tex]
Hence, the manager's prediction is not true because [tex]x \neq 35[/tex]
you have 5814 meters of rope that you need to cut into 27 meters sections. How many 27 meter section of rope will you be able to create, and how much rope will be left over as waste?
Answer:
215 sections of 27 meters of rope will be created and 9 meters will be left as waste
Step-by-step explanation:
A rope that is 5814 meters long needs to be cut into 27 sections
The number of 27 meter sections of rope that can be created can be calculated by dividing 5814 by 27
= 5814/27
= 215 remainder 9
Hence 215 sections of rope will be created and 9 meters of rope will be left as waste

Solve using zero product property: 2x^2-5x-6=0
Answer:
x = (5 + √73) / 4 or (5 - √73) / 4
Step-by-step explanation:
2x² - 5x - 6 = 0
x = [5 ± √(25 - 4(2)(-6)] / 2(2)
x = [5 ± √(25 + 48)] / 4
x = [5 ± √(73)] / 4
x = (5 + √73) / 4 or (5 - √73) / 4)
Jean says that if she multiplies 73×34, her product will automatically be less than 73 because 34 is less than 1, meaning the product will only be a part of 73. Is Jean correct?
Answer:
Yes, Jean is correct
Step-by-step explanation:
Given
[tex]73 * \frac{3}{4}[/tex]
Required
Determine the value of the result
When a positive integer is multiplied by a fraction, the result is always less than the integer
Solving further
[tex]Expression = 73 * \frac{3}{4}[/tex]
[tex]Expression = \frac{73 * 3}{4}[/tex]
[tex]Expression = \frac{219}{4}[/tex]
[tex]Expression = 54.75[/tex]
The result of the expression shows that the resulting value is less than 73.
Hence, Jean is correct

Answer:
I think C 130 probably wrong
Answer:
130 degrees
Step-by-step explanation:
Since there are vertical angles 2x and 3x-50 are the same. So you would do 2x=3x-50. The picture below shows how I got x=50. SO now you know x=50, it's important to remember that line AC equals 180 degrees. So what you nees to do is 180-50 to get what y equals. y should equal 130 degrees.
-3x+c=-3x+8 Describe the values of c for which the equation has no solution.
Answer:
any value other than 8
Step-by-step explanation:
If c = 8, the two sides of the equation say the same thing, so any value of x will satisfy the equation.
If c ≠ 8, there are no values of x that can make the equation true, hence no solutions.
There is no solution for any value of c that is not 8.
[tex]c=-3x+8+3x\\c=8[/tex]
If c = 8 then the solution is infinite. (because the equation is true)
[tex]-3x+7=-3x+8\\-3x+7+3x-8=0\\1=0[/tex]
If c < 8 then there're no solutions. (the equation is false)
[tex]-3x+9=-3x+8\\-3x+9+3x-8=0\\1=0[/tex]
If c > 8 then there're no solutions.
easy way. also if you look at the graph. It's literally impossible to have one intercept if the coefficient of x for both have the same operators and same absolute value like -2x+c = -2x + a or -3x+2 = -3x+5, we'll never get a single intercept. If we change like -3x+c = -5x+8, we might still get one solution.
what is - 5у - 25 = -40
Answer:
x=4
-5y+8x=-18
linear combination:
cancel out -5y with 5y. combine 8x and 2x
5y+2x=58
10x. combine -18 and 58 to get 40
10x=40
40/10=4
So that means..x=4

A gym charges a one-time fee of $75 to join, plus membership dues of $25 per month. Which equation represents the total cost, C, of belonging to the gym for m months? A. C = 25m – 75 B. C = 25m + 75 C. C = 75m + 25 D. C = 75m – 25
Answer:
C = 75 + 25m
Step-by-step explanation:
The one time fee is 75 and membership dues are 25 per month.
This corresponds to C = 75 + 25m because the one time fee is 75 and each month you pay 25.

9x + 7 - 3x + 20 = 39 { combine like terms}
9x -3x + 7 + 20 = 39
6x + 27 = 39 {Subtract 27 from both sides}
6x = 39- 27
6x = 12 {divide both sides by 6}
6x/6 = 12/6
x = 2

Write a simplified expression for the length of QR.
HELP ME PLASE
Answer/Step-by-step explanation:
Length of AC:
Given that AB = x + 2, and BC = 7x - 3, therefore,
[tex] (x + 2) + (7x - 3) = AC [/tex] (segment addition postulate)
Simply the expression for the length of segment AC
[tex] x + 2 + 7x - 3 = AC [/tex]
Collect like terms
[tex] x + 7x + 2 - 3 = AC [/tex]
[tex] 8x - 1 = AC [/tex]
Length of QR:
Given that PQ = 8y + 5, and PR = 13y + 25, therefore,
QR = (13y + 25) - (8y + 5) (PQ + QR = PR)
Simplify the expression to for the length of segment QR
QR = 13y + 25 - 8y - 5
Collect like terms
QR = 13y - 8y + 25 - 5
QR = 5y + 20
A 0.05-kg car starts from rest at a height of 0.95 m. Assuming no friction, what is the kinetic energy of the car when it reaches the bottom of the hill? (Assume g = 9.81 m/s2.) i dont understand can i get some help?
Answer:
The kinetic energy of the car is 0.466 J
Correct Answer: A. 0.466 J Explanation: If there is no friction, all of the gravitational potential energy of the car at the top of the hill will be converted to kinetic energy at the bottom of the hill. The potential energy of the car is equal to the product of its mass, height, and gravitational acceleration.0.05 kg • 0.95 m • 9.81 m/s2 = 0.466 J.
which of the following polynomials is in standard form (Picture)
Answer:
D
Step-by-step explanation:
A polynomial in standard form has the terms in ascending order.
In other words, the term with the largest degree is on the left, followed by the term with the second largest degree, etc.
The largest term in this polynomial is 2x³. Thus, we need to start with that.
The only choice that starts with 2x³ is choice D.
Thus, choice D is in standard form.
And examining choice D, we see that it is in ascending order all the way through.

Answer: dark blue
8 for a cd and start with $15
Step-by-step explanation: Here, notice that the value that we
don't know is how many CDs are purchased.
Since CD's cost $8, we multiply 8 by our variable, which is x.
So we have 8 times x or 8x.
In addition, since there is a one time fee
of $15 to begin, we add 15 to 8x.
So we have 8x + 15.

Step-by-step explanation:
In quadrant II, the x variable is less than 0 and the y variable is greater than 0
x < 0 , y > 0
Answer:
x < 0 and y > 0
Step-by-step explanation:
Quadrant II is the upper left quadrant.
In that quadrant, all x values are negative since it's to the left of the y-axis.
In that quadrant, all y values are positive since it's above the x-axis.
Answer: x < 0 and y > 0
If p - q = 4 and p² - q² = 24, what is the value of p + q?
Answer:
p=5, q=1
Step-by-step explanation:
5-1=4, 5^2-1^2=24
25-1=24
24=24
I just guessed and checked the solution for the answer
Answer:
p + q = 6
Step-by-step explanation:
p² - q² ← is a difference of squares and factors as
p² - q² = (p - q)(p + q) , then
p² - q² = 4(p + q) = 24 ( divide both sides by 4 )
p + q = 6
Solve for q. |q+8|≥2 Write a compound inequality like 1 < x < 3 or like x < 1 or x > 3. Use integers, proper fractions, or improper fractions in simplest form.
Answer:
-6≤q≤-10Step-by-step explanation:
Given the inequality |q+8|≥2, we are to solve for q. Note that the function inside modulus sign will return both negative and positive value.
For the positive function:
q+8≥2
Subtract 8 from both sides of the inequality.
q+8-8≥2-8
q ≥ -6
For the negative function;
-(q+8)≥2
open the parenthesis
-q-8≥2
add 8 to both sides
-q-8+8≥2+8
-q≥10
Multiply both sides by -1. Note that multiplying both sides of an inequality changes the direction of the inequality sign.
q≤-10
Combining both results i.e q ≥ -6 and q≤-10
q ≥ -6 can also be written as -6≤q
Combining -6≤q with q≤-10, this will give -6≤q≤-10.
Hence the result of the inequality function given is -6≤q≤-10.
