10%
Step-by-step explanation:
($3.95 - $3.45)/($3.95) × 100%
= ($0.50)/($3.95) × 100%
= 50/3.95 %
= 5000/395 %
= 1000/79 %
= 12,65 % → Round to the nearest tenth
≈ 10 %

turn 1.5(5 is repeating) into a mixed fraction
Answer:
14/9 or 1 5/9
Step-by-step explanation:
Answer:
1 [tex]\frac{5}{9}[/tex]
Step-by-step explanation:
We require 2 equations with the repeating digit placed after the decimal point
let x = 1.555... (2) Multiply both sides by 10
10x = 15.555.... (2)
Subtract (1) from (2) thus eliminating the repeating digits
9x = 14 ( divide both sides by 9 )
x = [tex]\frac{14}{9}[/tex] = 1 [tex]\frac{5}{9}[/tex]
Jethro used dimensional analysis to convert one rate of speed to another. Two of the conversion factors he used are 5280 ft/1 mi and 1 hr/60 min. What could be the units of the initial rate of speed and the final rate of speed? Justify your answer.
The units of the initial and final rates of speed are;
Initial rate of Speed = ft/hr
Final rate of speed = mi/min
We are told that the conversion factors he used are;5280 ft/1 mi and 1 hr/60 min
Now, the meaning of 5280 ft/1 mi denotes that;5280 ft mile is equivalent to 1 mile
This means that the initial distance unit used was ft while the final one was mile
Also, 1 hr/60 min denotes that;
1 hour is equivalent to 60 minutes.
This means that the initial time units used was hour while the final one was minute.
In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.Read more at; https://brainly.com/question/17734333

If 15% of 4x is 20 less than x, what is the value of x?
The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50

Answer: Slope = -7
Concept:
Here, we need to know the formula that helps to find the slope by two points.
The slope of a line is a number that describes both the direction and the steepness of the line.
Slope = Δy / Δx = (y₂ - y₁) / (x₂ - x₁)
Solve:
Given information
(x₁, y₁) = (1, 4)
(x₂, y₂) = (0, 11)
Given expression
Slope = (y₂ - y₁) / (x₂ - x₁)
Substitute values into the expression
Slope = (11 - 4) / (0 - 1)
Simplify the values in the parentheses by subtraction
Slope = (7) / (-1)
Simplify by division

640 divided by 2/5 how do I solve this
Answer:
Step-by-step explanation:
1600
Answer:
1,600
Step-by-step explanation:
When dividing with fractions, remember this rule!!!!
KEEP SWITCH FLIP
- Keep the first fraction
- Switch the sign from division to multiplication
- Flip the second fraction so it becomes its reciprocal (the numerator becomes the denominator and the denominator becomes the numerator)
Let's begin!
640 ÷ 2/5
We know that every number divided by 1 is itself, thus every numerator has an invisible 1 as its denominator. Now we can rewrite it as:
640/1 ÷ 2/5
First, keep 640/1. Then change the ÷ into a ×
640/1 × 2/5
Next, flip the 2/5 so the 5 is on top and 2 is on the bottom
640/1 × 5/2
And multiply across!
640 × 5 = 3,200
1 × 2 = 2
3,200/2 = 1,600
Your answer is 1,600!!
Hope this helps clear things up for you. Let me know if you any other questions :D

1.-2q-5=-11
2.w/3+2=5
Answer:
1. q = 3
2. w = 9
Step-by-step explanation:
1.
-2q - 5 = -11
Add 5 to both sides:
-2q - 5 + 5 = -11 + 5
-2q = -6
Divide both sides by 2:
-2q ÷ 2 = -6 ÷ 2
-q = -3
Divide both sides by -1:
-q ÷ -1 = -3 ÷ -1
q = 3
2.
w/3 + 2 = 5
Subtract 2 from both sides
w/3 = 3
Multiply both sides by 3:
w = 9
