Answer:
5/24
Step-by-step explanation:
Find a common denominator and multiply, then convert to its simplest form.
Find the value of the following expression
(2^8 5^-5 19^0) x [5^-2 over 2^3]^4 x 2^28 (5 points)
Write your answer in simplified form. Show all of your steps. (5 points)
Looks like the expression is
(2⁸ • 5⁻⁵ • 19⁰) • (5⁻² / 2³)⁴ • 2²⁸
First, any positive number raised to 0 is 1:
(2⁸ • 5⁻⁵ • 1) • (5⁻² / 2³)⁴ • 2²⁸
(2⁸ • 5⁻⁵) • (5⁻² / 2³)⁴ • 2²⁸
Exponents in a denominator can be rewritten as negative exponents in the numerator:
(2⁸ • 5⁻⁵) • (5⁻² • 2⁻³)⁴ • 2²⁸
Distribute the 4th power across the product 5⁻² • 2⁻³ :
(5⁻² • 2⁻³)⁴ = 5⁻⁸ • 2⁻¹²
so we have
(2⁸ • 5⁻⁵) • (5⁻⁸ • 2⁻¹²) • 2²⁸
Multiplication is associative, so we can ignore the parentheses. Combine factors with equal bases and simplify the exponents:
2⁸ • 5⁻⁵ • 5⁻⁸ • 2⁻¹² • 2²⁸
2⁸⁻¹²⁺²⁸ • 5⁻⁵⁻⁸
2²⁴ • 5⁻¹³
Rewrite the negative exponent as a positive one:
2²⁴ / 5¹³

Lili runs a small day care business, caring for 3 children.
• She earns $150 during regular work hours.
• She charges $0.50 for each minute parents are late.
The situation is represented by the equation below, where t is the total
dollar amount Lili earns each day and m is the total number of minutes
parents are late.
t=150 +0.5m
Which of the following solutions shows an amount of money Lili can
reasonably expect to earn each day?
Answer:
$150
Step-by-step explanation:
[tex]t=150 + 0.5m\\t=150+0.5*0\\t=150[/tex]
This is as we don't know how often the parents are late, nor if they are late. So we assume that the parents are never late.

Step-by-step explanation:
Bcs when u have a closed circle is when is less or equal to, and an open circle means greater/less to. And you have a closed bcs is less or equal to. So u look in the answers, you can already take two answers out which are the 2 and the 3 bcs they are open circle. Then x ≥ 98.6, then x is bigger than the 98.6 so the arrow would go to the right. And the answer would be first one
(How to do that in an easier way, Look at this ≥, the pointy side is aiming in the right so the arrow will go always to the right, THIS ONLY WORKS WHEN THE LETTER IS IN THE LEFT {EX. y ≤ 19, the arrow will be pointing in the left.)

Step-by-step explanation:
John spent $19.00 at the tuck shop. He bought 2 chocolate bars and 3 packets of
chips. The amount he spent on chips was $3.00 greater than the amount he
spent on chocolate. Jane wants to buy 3 chocolate bars and 3 packets of chips.
How much will it cost her?
Answer:
It will cost Jane $21.00
Step-by-step explanation:
As, cost of 1 chocolate = x
The cost of 1 packet of chips = $3 + x
So no. Of 2 chocolate bars = x + x = 2x
And no. Of packet of chips = ($3+x) + ($3+x) + ($3+x) = 3(3+x) = 9+3x
So now = cost Of chocolate + cost of chips = $19
So = 2x + 9+3x = 9 + 5x
So 9 + 5x = $19
So 5x = $19 - 9 = $10
So 5x =10
x = 10/5
x = 2
So cost of 2 chocolate = 2x = 2($2) = $4
And 3 chip packet = 9+3x = 9+3($2) = 9+6 =$15
So now total = $4 + $15 = $19
Now for John = 2 chocolates and 3 packets of chips = $19
Now for Jane she has 3 chocolates and 3 packets of chips, so she has one more chocolate amd now we know that 1 chocolate = $2
So we will just add one more chocolate
So Jane will pay = $ 19 + $2 = $21
So it will cost Jane = $21:00

what is the rate of change in y= 2x+3
Answer:
The Answer is 2
EXPLANATION:
y(x)=2x+3
y(x+Δx)=2(x+Δx)+3
=2x+2Δx+3
Δy=y(x+Δx)−y(x)
=(2x+2Δx+3)−(2x+3)
=2Δx
⇒Δy=2Δx, Δy/Δx =2
The rate of change in the equation of a line in slope-intercept form
y = 2x + 3 is 2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An equation of a line y = 2x + 3.
This is in slope-intercept y = mx + b, where 'm' is the slope.
Therefore, The rate of change in y = 2x + 3 is 2.

how can I find the slope to this I need help
Answer:
Your slope is -1
Step-by-step explanation:
Find the change in x and the change in y and put it in change in y over change in x.
Δx = -1 - -2 = 1
Δy = -1 - 0 = -1
Slope = rise over run = Change in y over change in x = Δy/Δx = -1/1
Therefore the slope is -1/1 which is written as just -1
