Answer:
0.0072
Step-by-step explanation:
=7.2 × 10^-3
=7.2 × 10/10000
=7.2 ×1/1000
=0.0072
Answer:
0.00072
Step-by-step explanation:
Step 1: We know that we will have 3 zeros because of the exponent, and the exponent happens to be negative, so we will have the 3 zeros in after the decimal point (obviously), but before any numbers.
Step 2: We will then convert the 7.2 into 72, and it will also go after the decimal point. It will also go after the 3 zeros.
Step 3: Put it all together. The 0 (0), the decimal point (0.), the three zeros (0.000), and the 72 (0.00072). 0.00072 is your answer!

3. A retailer sales one gold watch with a markup of 50%. Write an equation using (C) retail cost of watch and (s) for sale price, If the retailer sold the watch for $300, what was the cost to the retailer?
Answer:
a. S = 1.5C
b. C = $200
Step-by-step explanation:
Firstly, we want to write an equation using retail cost of watch and s for sale price
From the question, we are looking at a markup of 50%
Mathematically therefore;
S = C + (50/100 * c)
S = C + 0.5C
S = 1.5C
Now we want to calculate the cost to the retailer given that the watch was sold as $300 by the retailer
We use the equation:
S = 1.5C
300 = 1.5C
C = 300/1.5
C = $200

M is the midpoint in the segment find the indicated length XM
x+2
2x+3
NEED THIS ASAP
Answer:
XM = 1 unit
Step-by-step explanation:
It is given that, M is the midpoint in the segment.
Midpoint bisects the lines such that,
XM = MY
Put XM = x+2 and MY = 2x+3
x+2=2x+3
Taking like terms together,
x-2x=3-2
-x=1
x = -1
Put x = -1 in XM = x+2
(-1) + 2 = 1 = XM
So, the value of XM is 1 unit.

Prove: w = 2
Answer:
Step-by-step explanation:
Replace W with 2
(3 x 2) + (4 x 2) -2 = 12
6 + 8 -2 = 12
add 6 + 8 = 14
14 - 2 = 12
Subract 14 - 2 = 12
which your answer in the end would be 12 = 12
which proves W is 2

There are 8 people in a long, skinny, 9-seat canoe. Four are in the back, four are in the front and the middle seat is empty. The people from the back want to move to the front of the canoe and the people from the front want to move to the back. (Each group can only move in one direction.) Since they don’t want to risk falling into the water, they have to be very careful in the way that they move. Without capsizing the canoe, a person can move by “sliding” into the empty seat or by carefully “jumping” over
a single person into the empty seat. The goal is to exchange the people from the front and the back in as few “moves” as possible. How should it be done?
Challenge: How would your solution differ if there were 5 people in the back and 5 people in the front? How would it be similar? How would your solution differ if there were n people in the back and n people in the front?
1. Write the equation of a line that is parallel to y = -1/4 x - 6 that passes through the point (12,4).
Answer:
The answer is
[tex]y = - \frac{1}{4} x + 7[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
From the question the original line is
y = - 1/4x - 6
Comparing with the general equation above
Slope = - 1/4
Since the lines are parallel their slope are also the same
Slope of parallel line = - 1/4.
Equation of the line using point (12,4) and slope - 1/4 is
[tex]y - 4 = - \frac{1}{4} (x - 12) \\ y - 4 = - \frac{1}{4} x + 3 \\ y = - \frac{1}{4} x + 3 + 4[/tex]
We have the final answer as
[tex]y = - \frac{1}{4} x + 7[/tex]

4dy + 12 = 7dy, solve for y. Show how you solved it
Answer:
y = -12/(4d - 7d)
Step-by-step explanation:
Step 1: Write equation
4dy + 12 = 7dy
Step 2: Solve for y
Subtract 7dy on both sides: 4dy + 12 - 7dy = 0
Subtract 12 on both sides: 4dy - 7dy = -12
Factor out y: y(4d - 7d) = -12
Divide both sides by 4d - 7d: y = -12/(4d - 7d)
Hello! :)
First thing you do is add -7dy to both sides
4dy + 12 + -7dy = 7dy + -7dy
-3dy + 12 = 0
Next you will have to add -12 to both sides
-3dy + 12 + -12 = 0 + -12
-3dy = -12
Last thing you have to do is divide both sides by -3d
-3dy/-3d = -12/-3d
y = 4/d (ANSWER)

Hey there!☺
[tex]Answer:\boxed{x<2}[/tex]
[tex]Explanation:[/tex]
Let's start by simplifying both sides of the inequality:
[tex]5x-10<-3x+6[/tex]
Now add 3x to both sides:
[tex]5x-10+3x<-3x+6+3x\\8x-10<6[/tex]
In our third step, we will add 10 to both sides:
[tex]8x-10+10<6+10\\8x<16[/tex]
In our last step, we will divide both sides by 8:
[tex]\frac{8x}{8}=\frac{16}{8}[/tex]
Simplify 16/8:
[tex]\frac{16}{8}=2\\ x<2[/tex]
x<2 is your answer.
