Step-by-step explanation:
the first option : -(m¹²n⁶)/2
why ?
we can go through factor by factor of the multiplication/fraction.
2/-4 = -1/2
m⁹/m^-3 = m^(9 - -3) = m¹²
n⁴/n^‐2 = n^(4 ‐ -2) = n⁶
when we put all 3 factors back together, we get the mentioned result.
!HELP! What Is the Value of W??
Answer:
W equals 31.17
Step-by-step explanation:
Sally is 3 years older than Jill was 5 years ago. Write an algebraic expression for both of their ages. If Jill is 10, how old is Sally?
Answer: 13 (and Sally will always be 3 years older than Jill)
Step-by-step explanation:
Let S and J stand for Sally and Jill's ages. We are told:
(S-5) = (J-5)+3 [Sally is 3 years older than Jill was 5 years ago] The 5 years ago is the reason for the (S-5) and (J-5) expressions.If Jill is 10, how old is Sally?
(S-5) = (J-5)+3
(S-5) = (10-5)+3
S-5 = 8
S = 13
We actually don't really need an equation for solving this, other than the question asks us to write one. It doesn't matter how many years later, since Sally is 3 years older, she will always remain 3 years older, if we ignore the likelihood that the statement doesn't hold true for the period between their actual birthdays.

Answer:
[tex] {2}^{ \frac{3}{2} } = \sqrt[3]{ {2}^{2} }\\= \sqrt[3]{ {4}}[/tex]
The surd form is : [tex](\sqrt{2} )^3[/tex]
[tex](\sqrt{2} )^3=\sqrt{2}. \sqrt{2}. \sqrt{2}[/tex]
It gives in the approximate value is : 2.80
What is surd form?Surds are the square roots (√) of numbers that cannot be simplified into a whole or rational number. It cannot be accurately represented in a fraction. In other words, a surd is a root of the whole number that has an irrational value. Consider an example, √2 ≈ 1.414213. It is more accurate if we leave it as a surd √2.
We have from the question is:
Write in the surd form:
=> [tex]2^\frac{3}{2}[/tex]
Now, According to the definition:
Write like this:
[tex]2^\frac{3}{2}=((\sqrt{2} )^2)^\frac{3}{2}[/tex]
Cancel out the:
2 × 3/2 = 3
So, [tex](\sqrt{2} )^3=\sqrt{2}. \sqrt{2}. \sqrt{2}[/tex]
It gives in the approximate value is : 2.80
But, The surd form is : [tex](\sqrt{2} )^3[/tex]

3y > 2x + 12
2x + y< -5
Answer:
The vertices of both where they cross show (-4,1)
Step-by-step explanation:
3y > 2x + 12
x < 3(y - 4) / 2
y > 2 (x + 6) / 2
2x + y< -5
= x> -5
set = together
x < 3(y - 4) / 2 shows dotted ascending line attached through x=-6
This means x=--6 y = 0
x>-5 shows boundary dotted vertical line through -5
this means x = -5 y = 0
If it had been x ≥ -5 it would have been solid boundary line.
The area within the dotted lines create a right angle triangle where the far left angle shows ascends to (-6, 0) and crosses y at 0,4 however the shaded area will not got hat far and stop at -4,0 and the area below.
As seen attached when both are plotted with dash dotted boundary lines.
The vertices of both show (-5,1)
The edges on Zachary's snowboard are chlpped and dented from riding over rocks, so Zachary wants to buy a new one. He can't afford the board he wants, so he opens a hot chocolate stand near his house. Zachary figures out how many cups of hot chocolate he must sell to have enough money for the snowboard. One cold, snowy Saturday, Zachary sells 43 cups of hot chocolate. Now, he needs to sell 47 more cups to buy the snowboard. Which equation can you use to find the total number of cups c Zachary must sell to buy the snowboard?
Answer:
c-43=47
Step-by-step explanation:
Well this is kinda obvious.
He already sold 43 cups of hot choclate and he needed 47 more.
So the total amount of cups is (c) so we can make an equation like this
c-43 (since theres total which is unknown so ”c” and then Theres the already sold 43 cups).
c-43=47 (the 47 is the amount he needs to sell)
So final equation to determine total cups needed
c-43=47
Please help me solve this ASAP
Answer:
$21
Step-by-step explanation:
Let the amount Lori bought the shirt and the hat be $x, if she bought them at half off sale, the initial price of both item will be 2 × $x
If she spent $21 on both items, the initial price will have been 2 x $21 = $42 where x is $21
Original price of the hat and shirt is therefore $42. Since both are on half off sale, the initial price is the hat will be $42/2 = $21

using the graph, determine the coordinates of the roots of the parabola
Answer:
(-1, 4)
Step-by-step explanation:
Use of the coordinate plane.
The vertex of the parabola is 1 to the left and up 4.
Think of the vertex as where the curve starts.
Answer:
-3 and 1
Step-by-step explanation:
Hello!
The roots of the parabola are the intersections of the graph and the x-axis (y = 0).
Since the graph's vertex is above the x-axis and opens down, the graph has two roots.
The points of intersection are:
[tex](-3,0)[/tex][tex](1,0)[/tex]Therefore, the roots of the parabola are -3 and 1.

You spin the spinner and flip a coin. Find the probability of the compound event.
A spinner is divided into 5 equal regions. The sections are labeled 1, 2, 3, 4, and 5.
The probability of spinning a prime number and not flipping heads is
.
3/10
2, 3, and 4 are prime numbers. Those are three numbers worth. The maximum number on the spinner is 5 so you multiply 5 by 2 and get 10. Again, 3 numbers are prime numbers. So from there you add 3 and 10 as a fraction and get 3/10

180-161=19
Answer:
B) 19
Step-by-step explanation:
find the other angle of W first.
to do that, take 180 - 64
that makes angle W 116
add angle W and angle Y
116 +45 = 161

5. Which point lies on the line: y - 4 = -3(x + 2)?
Answer:
(- 2, 4 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 4 = - 3(x + 2) ← is in point- slope form
with (a, b ) = (- 2, 4 )

Diane is going to rent a truck for one day. There are two companies she can choose from, and they have
Company A charges $74 and allows unlimited mileage.
Company B has an initial fee of $65 and charges an additional $0.60 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
>
ISO
DO
Х
Answer:
Step-by-step explanation:
Company A Total Cost: Ca = $74
Company B Total Cost: Cb = $65+$0.60m, where m is the miles driven.
We want to find for what values of m with Company A charge less than Company B:
Ca < Cb ?
$74 < $65 + $0.60m
$9 < $0.60m
15 < m
m > 15 miles
Company A will cost less than Company B when less than 15 miles are driven. The costs are the same for 15 miles and higher for Company B beyond 15 miles.
How much simple interest does $4,678.00 earn in 529 days at a rate of 7.3%? Round to the nearest cent.
Answer:
$5,172.93
Step-by-step explanation:
We're gonna use the simple interest formula: P = A(1 + r(t))
P = final amount
A = starting amount (4,678)
r = rate (0.073)
t = years (529/365)
P = 4,678(1 + 0.073(529/365))
P = 5,172.9324
