a retailer makes a profit of 5% by selling a fan for Rs 735 at what price did he purchase the fan
[tex]\large\boxed{\pink{\sf \leadsto He \ purchased \ the \ fan \ for \ Rs 700. }}[/tex]
Step-by-step explanation:Given that , a retailer makes a profit of 5% by selling a fan for Rs 735 . So let us take CP be x .
Now , here
[tex]\implies \red{\sf Profit \ made \ by \ retailer = 5\% }[/tex]
Here we assumed CP to be x , and profit % is 5% . So , its SP will be
[tex]\implies SP = CP + 5\% \ of \ CP \\\\\implies Rs 735 = x + \dfrac{5}{100}x \\\\\implies \dfrac{100x+5x}{100}= Rs 735 \\\\\implies \dfrac{105x }{100}= Rs 735 \\\\\implies x = \dfrac{735\times 100}{105} \\\\\underline{\boxed{\orange{\tt \implies x = Rs 700 }}}[/tex]
Hence the CP of the fan was Rs 700 .pls hrlp me on this

ANSWER ASAP PLS YEY BRAINLIEST AND STUFFsolve for x 2/3=x-1/5
Answer:
x = 13/15
Step-by-step explanation:
If x - 1/5 = 2/3,
you can find x by doing 2/3 + 1/5.
2/3 = 10/15
1/5 = 3/15
10/15 + 3/15 = 13/15!

Answer:
Put the arrow facing the left with a non-filled up dot at the point between 31 and 32.
Step-by-step explanation:
x < 31.5 means that x is lesser than 31.5 and so x cannot be 31.5 itself.
< means lesser.
> means more than.
A filled up dot means that the number itself is included in the values of x.
A non-filled up dot means that the number itself is not included in the values of x.
An arrow facing left means lesser than that number.
An arrow facing right means more than that number.
Since 31.5 is not included in the values of x, we will be using the non-filled up dot.

MAKING AN ARGUMENT You and a friend are going hiking but start at different locations. You start at the trailhead and walk 5 miles per hour. Your friend
starts 3 miles from the trailhead and walks 3 miles per hour.
your friend
a. Using y to represent the distance each person walks and x to represent the number of hours walked, write a system of linear equations that represents this
situation.
Answer:
[tex]y = 5x[/tex] -- You
[tex]y = 3 + 3x[/tex] --- Your friend
Step-by-step explanation:
Given
You:
Trailhead implies the beginning so:
[tex]Start = 0\ mile[/tex]
[tex]Rate = 5miles/hour[/tex]
Your Friend
[tex]Start = 3\ mile[/tex]
[tex]Rate = 3miles/hour[/tex]
Required
Represent as an equation
From the question, we understand that:
[tex]y = distance[/tex]
[tex]x = number\ of\ hours[/tex]
So, the relationship between [tex]distance\ and\ time\ is:[/tex]
[tex]Distance = Start + Rate * Number\ of\ hours[/tex]
In terms [tex]of\ x\ and\ y[/tex], we have:
[tex]y = Start + Rate * x[/tex]
For you, the equation becomes:
[tex]y = 0+ 5* x[/tex]
[tex]y = 0+ 5x[/tex]
[tex]y = 5x[/tex]
For your friend, the equation becomes:
[tex]y = 3 + 3 * x[/tex]
[tex]y = 3 + 3x[/tex]

Step-by-step explanation:
Sum of angles in a triangle = 180°
Angle W = 180° - 62° - 57° = 61°
The shortest side is directly opposite the smallest angle.
(for acute angles)
Hence the shortest side is opposite 57°, which is VW.
Answer:
VUW
62 + 57 + x = 180
119 + x = 180
x = 180 -119
x= 61
therefore smallest angle is 57° (vuw)

Solve -9 <4x+3 11.
O A. x>-3 and xs 2
B. X> 3 or xs 2
O C. x>-3 or xs 2
O D. x > 3 and xs3
Answer:
c) x > -3 or x ≤ 2
Step-by-step explanation:
We are asked to solve this algebraic expression
-9 < 4x+3 ≤ 11.
We have two parts:
a) -9 < 4x+3
b) 4x+3 ≤ 11
For
a) -9 < 4x+3
Subtract 3 from both sides
-9 - 3 < 4x + 3 -3
-12 < 4x
-12/4 < x
-3 < x
x > -3
b) 4x+3 ≤ 11
Subtract 3 from both sides
4x + 3 -3 ≤ 11 - 3
4x ≤ 8
x ≤ 8/4
x ≤ 2
Hence, our answer is
x > -3 or x ≤ 2

Step-by-step explanation:
h (x) =4x-2 complete the function table
Note:
You did not mention the table of the points. But, I would try to clear your concept by taking 6 sample points.
Answer:
The table and the graph of the function h(x) = 4x-2 is also attached below.
Step-by-step explanation:
Given the function
[tex]h(x) = 4x-2[/tex]
substituting x = 0 in the function
h(0) = 4(0) -2 = 0 -2 = -2
Therefore, the point (0, -2) satisfies on the function.
substituting y = 1 in the function
h(1) = 4(1) -2 = 4 -2 = 2
Therefore, the point (1, 2) satisfies on the function.
substituting y = 2 in the function
h(2) = 4(2) -2 = 8 -2 = 6
Therefore, the point (2, 6) satisfies on the function.
substituting y = 3 in the function
h(3) = 4(3) -2 = 12 -2 = 10
Therefore, the point (3, 10) satisfies on the function.
substituting y = 4 in the function
h(4) = 4(4) -2 = 16 -2 = 14
Therefore, the point (4, 14) satisfies on the function.
substituting y = 5 in the function
h(5) = 4(5) -2 = 20 -2 = 18
Therefore, the point (5, 18) satisfies on the function.
Therefore, we conclude that table:
x h(x) = 4x-2
0 -2
1 2
2 6
3 10
4 14
5 18
The graph of the function h(x) = 4x-2 is also attached below.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x - y = 10
2x - y = 7
Step 2: Rewrite Systems
3x - y = 10
Subtract 3x on both sides: -y = 10 - 3xDivide -1 on both sides: y = 3x - 10Step 3: Redefine Systems
y = 3x - 10
2x - y = 7
Step 4: Solve for x
Substitution
Substitute in y: 2x - (3x - 10) = 7Distribute -1: 2x - 3x + 10 = 7Combine like terms: -x + 10 = 7Isolate x term: -x = -3Isolate x: x = 3Step 5: Solve for y
Define equation: 3x - y = 10Substitute in x: 3(3) - y = 10Multiply: 9 - y = 10Isolate y term: -y = 1Isolate y: y = -1Two rectangle are similar, the first 4 in wide and 15 in long. The second is 19 in. Wide. Find the length of the second rectangle?
Answer:
the length of the second rectangle is 33.75 in
Step-by-step explanation:
The computation of the length of the second rectangle is as follows
Let us assume the length of the second triangle be x
Now
The equation would be
4 ÷ 15 = 9 ÷ x
Now do the cross multiplication
4x = 15 × 9
4x = 135
x = 33.75 in
Hence, the length of the second rectangle is 33.75 in
A small deck of 5 cards consists of 3 red cards and 2 green cards.
Draw 7 times with replacement.
Find the probability that a red card is drawn exactly 5 times.
Answer:
0.0776
Step-by-step explanation:
Number of cards = 5 ; 3 red and 2 green
Since it is with replacement :
Probability of picking a replacement d ball: P(red) = required / total possible outcomes
P(red) = 3 / 5 = 0.6
Using binomial :
P(x =x) = nCx * p(x)^x * (1 - p)^(n - r)
P(x = 5) = 5C5 * (0.6)^5 * 0.4^0
P(x = 5) = 1 * 0.07776 * 1
P(x = 5) = 0.0776

Compute the reisduals for the trend line shown. y = -0.5x + 5
Answer:
X : 2__ 3 ___ 5 ___ 6 ___7
Y: 4 __3.5 __2.5___2 __ 1.5
Step-by-step explanation:
Given tbe equation for tbe residual :
y = -0.5x + 5
X : 2, 3, 5, 6, 7
X = 2
Y = - 0.5(2) + 5 = 4
X = 3
Y = - 0.5(3) + 5= 3.5
X = 5
Y = - 0.5(5) + 5 = 2.5
X = 6
y = -0.5(6) + 5 = 2
X = 7
y = -0.5(7) + 5 = 1.5
X : 2__ 3 ___ 5 ___ 6 ___7
Y: 4 __3.5 __2.5___2 __ 1.5
The table shows the number of points the Lions scored and allowed in 8 games. Based on the data, which sentence is true? The median for points scored is greater than the median for points allowed. Lions' Games The mode for points allowed is greater than the mode for points scored. Points Scored 24 21 18 17 24 31 22 28 Points Allowed 16 10 27 21 21 24 28 The mean for points allowed per game is greater than the mean for points scored per game. The range for points scored is greater than the range for points allowed.
Answer:
The range for points scored is greater than the range for points allowed.
Step-by-step explanation:
Points scored: 175
Points allowed: 168
The true sentence is that the range for points scored is greater than the range for points allowed.
What is mean?
The mean of observations is equal to the ratio of sum of all the observations and the number of observations.
Points scored by the lion in the 8 games are
24 + 21 + 18 + 17 + 24 + 31 + 22 + 28 = 175.
Points allowed in the 8 games are
16 + 10 + 27 + 21 + 21 + 24 + 28 = 168
Thus, the range for points scored is greater than the range for points allowed.
