Answer: See explanation
Step-by-step explanation:
Sita bought a sofa set for Rs 30,000 and sold the sofa set at a loss of 5%. The loss on the sofa will be:
= 5% × 30000
= 5/100 × 30000
= 0.05 × 30000
= 1500
Selling price of the sofa = 30000 - 1500 = 28500
Sita bought a dining set for Rs 20,000 and made a profit of 5% on the dining set. The selling price of the dining set will be:
= 20000 + (5% × 20000)
= 20000 + (0.05 × 20000)
= 20000 + 1000
= 21000
The cost price of the sofa and dining set will be:
= Rs 20000 + Rs 30000
= Rs 50000
The selling price of the dining set will be:
= Rs 28500 + Rs 21000
= Rs 49500
The net result of the transaction is will be:
Selling price - Cost price
= 49500 - 50000
= -500
There's a net loss of $500

Step-by-step explanation:
========================================================
Explanation:
Let's convert the mixed number 5 & 1/3 to an improper fraction.
The formula to use is
a & b/c = (a*c + b)/c
So,
a & b/c = (a*c + b)/c
5 & 1/3 = (5*3 + 1)/3
5 & 1/3 = 16/3
Imagine you had 16 pieces of candy, and imagine you wanted to divide that up amongst 3 friends. Each friend would get 15/3 = 5 whole pieces. There would be 1 candy left over. The 5 and 1 help then form the 5 & 1/3. So this is one way to visualize how 5 & 1/3 is the same as 16/3.
Another way to see why this works is to note how 16/3 = 5.333 approximately. The '5' before the decimal point is the whole part of the mixed number 5 & 1/3; the decimal portion 0.333 is the approximate value of the fractional part 1/3.
------------------
The total length of fencing needed is 16/3 yards. Each section is 2/3 of a yard long. Since both denominators are "thirds", we can ignore them. An equivalent problem is this: "He needs 16 yards of fencing and each section is 2 yards long"
Based on the new problem without fractions involved, we can see that he'll need 16/2 = 8 sections in total.
You should find that dividing (16/3) over (2/3) will lead to 8 as well. You could say this:
(16/3) divide (2/3) = (16/3)*(3/2) = (16*3)/(3*2) = 48/6 = 8
-------------------
An alternative method:
Let's start with 2/3 of a yard. That doubles to 4/3 which is the same as 1 & 1/3. Think of it as 4/3 = (3+1)/3 = 3/3+1/3 = 1+1/3 = 1 & 1/3.
Next, we'll double 1 & 1/3 to land on 2 & 2/3. You simply multiply each '1' by 2 to end up with those '2's shown.
Now we'll double 2 & 2/3 like so:
2*(2 & 2/3) = 2*(2 + 2/3) = 4 + 4/3 = 4 + (1+1/3) = 5 + 1/3 = 5 & 1/3
The act of doubling exactly three times leads to us ultimately multiplying by 2*2*2 = 8, so he needs 8 sections that are each 2/3 of a yard long.
-------------------
Whichever method you prefer, the final answer is 8 sections.

Tavon has a gift card for $80 that loses $3.50 for each 30-day period it is not used. He has another gift card for $70 that loses $3 for each 30 day period it is not
used
aWrite and solve an equation for the number of 30-day periods until the value of the gift cards will be equal
b. What will the value of each card be when they have equal value?
a. If x is the number of 30-day periods, then the equation can be used to find the number of 30 day periods until the values of the gift cards will be equal.
(Type an equation. Use integers or decimals for any numbers in the equation.)
Answer:
(a). 20 ; (b). $10.00 ;
Step-by-step explanation:
(a). 70 - 3x = 80 - 3.50x
- 3x + 3.50x = 80 - 70
0.5x = 10
x = 10 ÷ 0.5
x = 20 ( 30-day periods )
(b). $70.00 - $3.00(20) = $10.00
The number of days will be 20 days. Then the values of the gift cards will be equal and will be $10.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Tavon has a gift card for $80 that loses $3.50 for each 30-day period it is not used. He has another gift card for $70 that loses $3 for each 30 days period it is not used.
Let y be the amount left of gift cards after x days and x be the number of days. Then the equation will be
y = 80 - 3.5x ...1
y = 70 - 3x ...2
From equations 1 and 2, we have
80 - 3.5x = 70 - 3x
0.5x = 10
x = 10 / 0.5
x = 20 days
The values of the gift cards will be equal and will be
y = 80 - 3.5(20)
y = 80 - 70
y = $10
The values of the gift cards will be equal and will be $10.

Determine whether the following statement is true or false.
The graph of f(x) = (x + 2)2 + 4 has its vertex at (2,4).
Choose the correct answer below.
O True
0 False
Answer:
Step-by-step explanation:
No it doesn't. When you get stuck on a question like this one, you should go to Desmos and graph the equation. I've done that for you.
Correctly stated the equation should read f(x) = (x + 2)^2 + 4
As you can see from the graph the vertex is at -2,4. To find the x value of the vertex, create a small equation
x + 2 = 0
x = - 2
That will turn what is inside the brackets into 0. The value for x is always what will turn (x + a) to zero.

Last week, Juliet ran 22 kilometers. This week, she plans to run 2\frac{2}{5}2 5 2 times as far as last week. How many kilometers does Juliet plan to run this week?
Answer: 52.8 kilometers
Step-by-step explanation:
This week she plans to run 2²/₅ times as much as last week.
If she ran 22 kilometers last week, then multiple 22 by 2²/₅ to find out the number of kilometers to run this week.
First convert the improper fraction to a proper one:
2²/₅ = 12/5
= 12/5 * 22
= 264/5

Pi
StartFraction 3 pi Over 2 EndFraction
2 pi
Answer:
1) 270 degrees
2) pi/4 rad
Step-by-step explanation:
1.) For which value of theta is sine theta = negative 1?
Given
sintheta = -1
theta = arcsin(-1)
theta = -90degrees
Since sin is negative in the third and 4th quadrant
In the third quadrant, theta = 180 + 90 = 270degrees
In the fourth quadrant, theta = 360 - 90 = 270 degrees
Hence the required value of theta is 270degrees
2) Given the radius of the circle to be 1, the y axis value will also be 1 units
Opposite = 1
adjacent = 1
hyp = √1²+1²
hyp = √2
sin theta = opp/hyp
sin theta = 1/√2
theta = arccsin(1/√2)
theta = 45 degrees
Express in radians
45 degrees = pi/4 radians
Hence the required angle in the first quadrant is pi/4 rad
Answer:
3pi/2
Step-by-step explanation:
that is only one that makes sine negative. others make it 0 or positive
