Answer:
z<-4
Step-by-step explanation:
-2z-5>3
Add 5 to both sides.
-2z>8
Divide both sides by -2.
Z<-4
The sign must change because you are dividing by a negative.

The selling price of an item is $720. It is marked down by 30%, but this sale price is still marked up from the cost of $420. Find the markup from cost to sale price.
Answer:
$84
Step-by-step explanation:
720x30=21600
21600/100=216
216=markdown (as a number instead of a percentage)
Now subtract that like this
720-216=504
504= sale price
Then do this
504-420=84
Therefore it is $84

(-3s+2t)(4s-t)
Answer:
- 12s² + 11st - 2t²
Step-by-step explanation:
Given
(- 3s + 2t)(4s - t)
Each term in the second factor is multiplied by each term in the first factor, that is
- 3s(4s - t) + 2t(4s - t) ← distribute both parenthesis
= - 12s² + 3st + 8st - 2t² ← collect like terms
= - 12s² + 11st - 2t²

(a) Write the expression in expanded form. log(7x^3/z)
(b) Write the expanded form as a simplified single log. 3log(5) + 2log(x) – log(25)
Step-by-step explanation:
log(7x³/z) = log(7) + log(x³) - log(z).
3log(5) + 2log(x) - log(25) = log(125) + log(x²) - log(25) = log(125x²/25) = log(5x²).

Step-by-step explanation:
[tex]We\ are\ given\ that,\\Coordinates\ of\ Endpoint\ O=x_1,y_1=(-2,9)\\Coordinates\ of\ Endpoint\ A=x_2,y_2=(6,-3)\\As\ we\ know\ that,\\The\ length\ of\ line\ segment\ OA\ or\ u\ is\ the\ distance\ between\ its\ endpoints\\ O\ and\ A.\\Hence,\\The\ linear\ distance(d)\ between\ any\ two\ points\ on\ a\ cartesian\ plane,\\ is\ given\ by\ the\ Formula:\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\Hence\ here,\\[/tex]
[tex]In\ order\ to\ find\ the\ distance\ between\ O\ and\ A,\ we\ just\ need\ to\ plug\ in\\ its\ respective\ coordinates\ in\ the\ Formula\ above.\\Hence,\\Distance\ between\ O\ and\ A= \sqrt{(6-(-2))^2+(-3-(9))^2} \\Distance\ between\ O\ and\ A= \sqrt{(6+2)^2+(-3-9)^2}\\Distance\ between\ O\ and\ A= \sqrt{(8)^2+(-12)^2}\\Distance\ between\ O\ and\ A= \sqrt{64+144}\\Distance\ between\ O\ and\ A= \sqrt{208}\\Distance\ between\ O\ and\ A \approx 14.42\ or\ 14.4\ units[/tex]

If you were to roll the dice one time what is the probability it will NOT land on a 2?
Answer:
5 / 6
Step-by-step explanation:
Given that:
Probability that a dice rolled once will not land on 2
Probability = required outcome / Total possible outcomes
Total possible outcomes = (1, 2, 3, 4, 5, 6)
Required outcome = 2
P(not land on 2) = 1 - p(land on 2)
P(land on 2) = 1/6
P(not land on 2) = 1 - 1/6
P(not land on 2) = 5/6
A 15-foot log is split into 2 pieces. How long are the pieces if the longest piece is 1.5ft shorter than two of the shorter pieces?
HELP
Answer:
8.25 ft & 6.75 ft
Step-by-step explanation:
So we know it's split into two pieces, right? So normally that would be 7.5 ft each. But one is 1.5 ft longer than the other. So as a result, I divided that by 2 to add 0.75 ft to piece one and subtract 0.75 ft from piece two's length. So, the longer piece is 8.25 ft, and the shorter one is 6.75 ft.
Answer:
Solution given:
total length=15foot
splits into 2 pieces
let shorter pieces be x.
we have longer pieces =2x-1.5ft
Now
total length=x+2x-1.5ft
15 ft =3x-1.5ft
15+1.5=3x
x=[tex] \frac{16.5}{3} [/tex]=5.5ft
Now
shorter length: 5.5ft.
longer length:2*5.5-1.5=9.5ft.

Answer:
Two perpendicular segments are segment AB and segment CD
Step-by-step explanation:
The given construction with the straight edge and the compass gives;
1) A straight line CD
2) A line AE from the center of the circle A, to the line CD
3) The circles A and B constructed from the centers A and B respectively
Therefore
Whereby the points A and B are joint by the line AB, we have;
The line passing through the points C and D is the perpendicular bisector of line AB
Therefore, two perpendicular segments are segment AB and the perpendicular bisector of AB which is segment CD
What is the median of the following numbers?

Median = 5
Mean = 5.4444444444444
Mode: 3
Range = 9
Minimum = 1
Maximum = 10
How to find Median:
Arrange your numbers in numerical order. Then the second step is to have an odd number, divide by 2 and round up to get the position of the median number. The last step is to find the even number and if you have it, divide it by 2.

2.5t=6-0.5t+152.5t=6−0.5t+15

The top of a ladder slides down a vertical wall at a rate of 0.32 m/s. At the moment when the bottom of the ladder is 8 m from the wall, it slides away from the wall at a rate of 0.6 m/s. How long is the ladder?
Answer:
The length of the ladder = 17 meters(17m)
Step-by-step explanation:
The formula to find the Length of the ladder is given as:
L² = x² + y²
Where L = Length of the Ladder
Let x = 8m
We solve for y
From the above question, we are told that:
The top of a ladder slides down a vertical wall at a rate of 0.32 m/s.
Hence: (-0.32)y = -0.32y
At the moment when the bottom of the ladder is 8 m from the wall, it slides away from the wall at a rate of 0.6 m/s. Hence:
8(0.6) - 0.32y = 0
4.8 = 0.32y
y = 4.8/0.32
y = 15m
Hence:
L² = x² + y²
L² = 8² + 15²
L² = 64 + 225
L² = 289
Square root both sides
L = √289
L = 17m
The length of the ladder = 17 meters(17m)
