Sita bought a sofa set for Rs 30,000 and a dining set for Rs 20,000. He sold the sofa set at a loss of 5% but made a profit of 5% on the dining set. The net result of the transaction is?
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
The length of one base of a trapezoid is 19 meters and the length of the median is 23 meters. Find the length of the other base,
Answer:
27
Step-by-step explanation:
19+x/2=23
19+x=46
x=27
or 19-23=4
23+4=27
The length of the other base of the trapezoid is 27 meters.
What is a Trapezoid?A trapezoid is a polygon with four sides, it has one pair of parallel sides.
The length of the base of a trapezoid is 19 meters.
The length of the median is 23 meters.
The median in a trapezoid is a line that is in the drawn in the mid way of the two non-adjacent sides.
The value of median is half of the bases added together.
Median = (1/2) ( Base₁ + Base₂)
Substituting the values in the formula to obtain the value of the other base.
Let x be the length of the other base,
23 = (1/2) * ( 19 + x)
23 *2 = 19+x
46 = 19 +x
x = 27 meters
The length of the other base is 27 meters.

Calculate the volume of liquid that would fill the bowl of the glass. Show all your work.
Answer:
52.36
Step-by-step explanation:
Formula to find volume in a cone is
V = pi • radius^2 h/3
So we fill in the numbers
V = pi •
the radius is half of diameter,
The diameter is 5
So it's
V = pi • 2.5
since it's half of 5
V = pi • 2.5^2 h/3
the height is 8 so we fill it in
V = pi • 2.5^2 8/3
When calculated, you get..
52.36
The volume of the liquid which can fill the bowl of the glass (in shape of cone) with the liquid is 49.74 cm³.
What is of volume of solid?Volume of solid is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
The volume of the cone can be given as,
[tex]V=\dfrac{1}{3}\pi r^2\sqrt{l^2-r^2}[/tex]
Here, (r) is the radius of the base of the cone and (l) is the slant height of the cone.
Here, the diameter of the cone is 5 cm. thus the radius of the cone is,
[tex]r=\dfrac{5}{2}\\r=2.5\rm cm[/tex]
The slant height of the cone is 8 cm. Thus, put the value to find the volume of cone as,
[tex]V=\dfrac{1}{3}\pi (2.5)^2\sqrt{(8)^2-(2.5)^2}\\V\cong 49.74\rm cm^3[/tex]
Thus the volume of the liquid which can fill the bowl of the glass (in shape of cone) with the liquid is 49.74 cm³.

Melanie is going to invest in an account paying an interest rate of 5.2% compounded
monthly. How much would Melanie need to invest, to the nearest hundred dollars,
for the value of the account to reach $19,600 in 19 years?
Answer:
7300
Step-by-step explanation:
I got it right
Melanie would need to invest an amount of $7300.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
The final amount in a compound interest can be calculated using the formula,
A = P (1 + [tex]\frac{r}{n}[/tex] )^(n t)
Here A is the final amount, P is the principal value, r is the rate of interest, n is the number of times interest is compounded per year and t is the number of years.
Given,
A = $19,600
r = 5.2% = 5.2/100 = 0.052
Since it is compounded monthly, n = 12
t = 19 years
Substituting,
19,600 = P (1 + [tex]\frac{0.052}{12}[/tex])^ (12 × 19)
19,600 = P (1.0043)^(228)
19,600 = P (2.68)
P = 19,600 / 2.68
P = 7313.0767 ≈ 7300 to the nearest hundred
Hence the value of the account will reach $19,600 n 19 years if she invest an amount of $7300.

Phil is riding his bike. He rides 25 miles in 2 hours, 37.5 miles in 3 hours, and 50
miles in 4 hours. Find the constant of proportipnality and write an equation to
describe the situation. Let x represent the number of hours.
The equation that describes the relationship is y =
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
The equation is

Explanation:
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25
miles

2
hours

A direct proportionality will always result in an equation that resembles this:
