Answer:
5/21
Step-by-step explanation:
10/7 is a fraction, and if you divide a fraction a/b by c (a/b)/c, then the answer is a/bc, which is 10/6*7, or 10/42, which reduces to 5/21.
1. 100 kilometers at 20 km/h?
2. 180 kilometers at 45 km/h?
Nonsense will be reported!!
Plss help me on this!! I Have Already get the answer but my friend said rwong!!
Answer:
1. 5 hours
2. 4 hours
Reason:
Formula for speed is speed = [tex]\frac{distance}{time}[/tex] , if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.
[tex]\\ \rm\hookrightarrow Speed=\dfrac{Distance}{Time}[/tex]
[tex]\\ \rm\hookrightarrow Time=\dfrac{Distance}{Speed}[/tex]
So
#1
[tex]\\ \rm\hookrightarrow Time=\dfrac{100}{20}=5h[/tex]
#2
[tex]\\ \rm\hookrightarrow Time=\dfrac{180}{45}=4h[/tex]

Answer:
1/20
Step-by-step explanation:
marked down from 16.50 per kg to 12 per kg. What percentage reduction is this?
Answer:
-27.27 %
Step-by-step explanation:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((12 - 16.5) / 16.5) * 100 = -27.27 %
27.3%
Find the different:
16.50-12=4.5
Find the percentage reduction:
4.5/16.50×100
=27.27272727
=27.3%(3 sig.fig)

14x + 11 > -227 I NEED HEP
Answer: [tex]x < -27.7142857[/tex]
Step-by-step explanation:
First, you move 11 to the right side, resulting in 14x > -338
Then you divide -388 by 14, which is 27.7142857, so the final statement is
[tex]x < -27.7142857[/tex]Could you give me the brainiest please if I am right?
Answer:
x > -17
Step-by-step explanation:
1. You would subtract 11 from both sides. Like this (14x + 11 - 11 > -227-11)
2. Simplify it (14x > -227 - 11)
3. Next, you would subtract -227 by 11 which will give you -238 (14x > -238)
Isolating the X:
1. Divided both sides by 14 (14x/14) and (-238/14)
2. Simplify the fraction (x > -238/14)
3. You would have to find the GCF of the numerator and the denominator (x > -17 · 14/1 · 14)
4. You factor out and cancel the GCF (x > -17)
Show your work when turning 2 1/8 as an improper fraction.
Answer:
17/8
Step-by-step explanation:
2⅛ as an improper fraction.
2 x 8 = 16
16 + numerator (1) =17.
17/8 is 2⅛ as an improper fraction
Solution:
To convert the fraction into improper fraction, multiply the whole number with the denominator and add the numerator to the product. The denominator will remain the same.
2 1/8=> {(2 x 8) + 1}/8=> {16 + 1}/8=> 17/82 1/8 in improper fraction is 17/8.
Two similar solids have a scale factor or 6:7.
What is ratio of their volumes, expressed in lowest terms?
Answer:
ratio's of their volume is 216 : 343
Explanation:
Let volume of one solid be x, another be y
given scale factor = 6 : 7
volume of solid = a³
solve:
[tex]\sf \frac{x}{y} = (\frac{6}{7} )^3}[/tex]
[tex]\sf \frac{x}{y} = \frac{216}{343} }[/tex]
║ Therefore volume of one solid is 216 and another 343 ║
In ratio form:
216 : 343
Answer:
Ratio's is 216 : 343
Step-by-step explanation:
Volume of one solid is x, and the other is y
Scale factor = 6 : 7
Volume of solid = a³
Solve:
[tex]\frac{x}{y}=(\frac{6}{7})^{3}[/tex]
[tex]\frac{x}{y}=\frac{216}{343}[/tex]
Hence, the volume of one solid is 216 and the other is 343
As a Ratio:
216 : 343
What is the mean? Thank you math experts
The Mean is simply the average of all the numbers. Meaning(see what I did there):
The answer is D) 49.3
To find the Mean all you have to do is find the average for all the numbers. That's what a Mean is. So put simply all you have to do is add all the numbers and divide by how many there are.

Complete the definition of the price wise defined function by identifying the domain of each piece.
Answer: a=1 b=3
Step-by-step explanation: the x for each of the points are 1 and 3
A domain is the range of the assigned value (x), the domain of this piecewise-defined function are: a= 1 and b= 3
Based on the graph of the piecewise-defined function, we can deduce the following points;
When x < 1, we have:
f(x) = -x.
When 1 ≤ x < 3, we have:
f(x) = -1.
When x ≥ 3, we have:
f(x) = (x - 3)² - 1.
Since a domain is the range of the assigned value (x), we have:
a = 1.
b = 3.

Meena mowed 9 lawns in 18 hours. What was her rate of mowing in lawns per hour?
Answer:
2
Step-by-step explanation:
Because
2 hours=1 lawn
4 hours=2 lawns
6 hours=3 lawns
8 hours=4 lawns
10 hours=5 lawns
12 hours=6 lawns
14 hours=7 lawns
16 hours=8 lawns
18 hours=9 lawns
Another way to think of it is 18 hours by 9 lawns=2 so each 2 hours the lawns should be half like how 12 hours is 6 lawns or how 16 hour is 8 lawns.
Hope this helps have a great afternoon:)
The rate of mowing the lawn by Meena is 2 units per hour, at this rate she will mown 9 lawns in 18 hours.
Given, that Meena mowed 9 lawns in 18 hours.
The breakup of lawn mowing by Meena can be described as below.
She mowed 9 lawns in 18 hours.
So, the breakup :
2 hours = 1 lawn
4 hours = 2 lawns
6 hours = 3 lawns
8 hours = 4 lawns
10 hours = 5 lawns
12 hours = 6 lawns
14 hours = 7 lawns
16 hours = 8 lawns
18 hours = 9 lawns
In this way she mowed 9 lawns in 18 hours with a rate of 2 lawns per hour.

Step-by-step explanation:
(a+b)(a+b) = a^2 + ab + ab + b^2 which simplifies to a^2 + b^2 + 2ab
(a^2 + b^2 + 2ab)(b-a) = a^2b + -a^3 + b^3 -ab^2 + 2ab^2 -2a^2b which simplifies to a^2b -a^3 +b^3 +ab^2 - 2a^2b

B. (x+0, y+1)
C. (x+2, y-1)
D. (x+1, y-1)
Answer: C
Step-by-step explanation:
We can test point A.
After the dilation, A has coordinates (0, 0).
After the reflection, A has coordinates (0, 0).
Since we know that after the translation, (0,0) has to map onto (2,-1), we know the translation is 2 units right and 1 unit down.

The perimeter of a nonagon is the sum of its side lengths
The perimeter of the regular nonagon is 840.7 units
How to determine the perimeterThe in-radius of the regular nonagon is given as:
r =17
The perimeter is then calculated as:
[tex]P = \frac{18r}{\tan(pi/9)}[/tex]
Substitute 17 for r
[tex]P = \frac{18 * 17}{\tan(pi/9)}[/tex]
Evaluate the product of 18 and 17
[tex]P = \frac{306}{\tan(pi/9)}[/tex]
Evaluate the quotient
[tex]P =840.7[/tex]
Hence, the perimeter of the regular nonagon is 840.7 units
