Step-by-step explanation:
Convert [tex]\displaystyle 5\%[/tex]to a fraction and divide nine by it:
[tex]\displaystyle 9 = 5\%{n} \hookrightarrow \frac{9}{\frac{1}{20}} = \frac{\frac{1}{20}n}{\frac{1}{20}} \\ \\ \boxed{180 = n}[/tex]

A group of friends are having a 400 m race julze can run 25 meters in 4 seconds alex can run 60 meters in 10 seconds jaheim can run 6.5 meters Yuseph can run 100 meters in 15 seconds if each of them could keep their constant speed who would win the race explain your answer.
Answers
Answer:
Yuseph would win the race because he has the highest speed and will run 400m in 60 seconds
Step-by-step explanation:
Race = 400m
julze can run 25 meters in 4 seconds
= 400m / 25m × 4 seconds
= 16 × 4
= 64 seconds
alex can run 60 meters in 10 seconds
= 400m / 60m × 10 seconds
= 6.67 × 10
= 66.7 seconds
Yuseph can run 100 meters in 15 seconds
= 400/100 × 15 seconds
= 4 × 15
= 60 seconds
jaheim can run 6.5 meters
Yuseph would win the race because he has the highest speed and will run 400m in 60 seconds

Find the Pattern

0 ↦ −5
−1 ↦ −5.3…
−9 ↦ −8
I have to find a formula to get from the left number to the right number, but I cannot find the pattern. How do I do this, and what is the solution?
Answers
Answer: y = (1/3)x - 5
This is the same as writing [tex]y = \frac{1}{3}x-5[/tex]
======================================================
Explanation:
Assume we have a linear pattern matching the form y = mx+b.
The first row has x = 12 lead to y = -1
The second row has x = 3 lead to y = -4
This produces the two points (12,-1) and (3,-4)
Let's find the slope through those points.
m = (y2-y1)/(x2-x1)
m = (-4-(-1))/(3-12)
m = (-4+1)/(3-12)
m = -3/(-9)
m = 1/3
The slope is 1/3.
The y intercept is b = -5 since x = 0 leads to y = -5
We go from y = mx+b to y = (1/3)x - 5
--------------------------
To verify we have the correct equation, plug in each left side value as x values.
Let's try x = 12
y = (1/3)x - 5
y = (1/3)*12 - 5
y = 4 - 5
y = -1
This shows that the input x = 12 maps to the output y = -1
i.e. 12 ↦ −1 is the case here.
Repeat for x = 3
y = (1/3)x - 5
y = (1/3)*3 - 5
y = 1 - 5
y = -4
We can see that 3 ↦ −4 occurs.
I'll let you check the others, but you should find that the other mappings hold true as well. Therefore, the answer has been fully confirmed.
m<a = 3x+11 and m<b = 17x-91. The angles are supplementary. Find the value of x.
Answers
Answer:
x = 13
Step-by-step explanation:
Supplementary means 180 degrees.
Since we are finding the supplement, we are going to add both angles together and solve for x.
3x + 11 + 17x - 91 = 180
~Combine like terms
20x - 80 = 180
~Add 80 to both sides
20x = 260
~Divide 20 to both sides
x = 13
Best of Luck!
Answer:
Since the measure of both angles are supplementary, its easy to form the equation.
3x+11+17x-91 = 180
20x-80 = 180
20x = 100
x = 5
m<a = 3x+11
= 3(5)+11
= 15+11
= 26
m<b = 17x-91
= 17(5)-91
= 85-91

if a shopkeeper sold a watch for Rs 640 at a loss of 20%,find the cost price of the watch
Answers
Answer:
Rs 800
Step-by-step explanation:
Selling Price =Rs640
Loss=20%
Let the cost price of the watch be Rs x.
SP=CP-20%of CP
or, 640=x-x/5
or, 640=4x/5
or, 4x=640*5
or,x=3200/4
Therefore, x=Rs 800. The cost price of the watch is Rs 800.

Step-by-step explanation:
The room's width should remain unchanged at 300 inches.
If the question is asking room of the same area but length shortened to 10 inches, then the answer is 400*300/`10 = 12000 inches.

Answer:
[tex]y= \frac{5}{9}x - 2[/tex]

Let's write the equation in the slope-intercept form! In the slope-intercept form, y= mx +c, m is the slope and c is the y-intercept.
[tex]\textcolor{blueviolet}{\text{\textcircled{1} Find \: the \: slope}}[/tex]
[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]
where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
Slope
[tex] = \frac{ - 2 - ( - 7)}{0 - ( - 9)} [/tex]
[tex] = \frac{ - 2 + 7}{0 + 9} [/tex]
[tex] = \frac{5}{9} [/tex]
[tex]\textcolor{blueviolet}{\text{\textcircled{2} Substitute \: value \: of \: slope}}[/tex]
[tex]y = \frac{5}{9} x + c[/tex]
[tex]\textcolor{blueviolet}{\text{\textcircled{3} Substitute \: a \: pair \: of \: coordinates}}[/tex]
When x= 0, y= -2,

there are 128 fluid ounces in 1 gallon, that means that 25 gallons is 25 * 128 = 3200 ounces.
