The marked price of a water cooler is $ 4500. The shopkeeper offers an off-season discount of 18% on it. Find its selling price.
Answer:
$3690
Step-by-step explanation:
Let's first find what percent of the original price it is being sold for.
100%-18%=82%
The water cooler is being sold for 82% of its original price.
Let's now find 82% of 4500.
0.82*4500=3690
The selling price is $3690
Answer:
3690
Step-by-step explanation:
the original price is 4500
for decreasing or discount we use this formula x discount upo 100 multiply by the original price. so for this question if we apply the formula it will be
18upon 100 x4500. the answer comes as 810. noww we subtract the original price from the discounted price. so 4500-810=3690. comes as ur selling price

The lines shown below are parallel. If the green line has a slope of 5, what is
the slope of the red line?
Answer:
D
Step-by-step explanation:
By definition, any two lines that are parallel must have the same slope, since they are angled the same amount (they travel the same amount up over a certain sideways distance). Hope this helps!
The required slope of the red line is equal to 5. Option D is correct.
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The slope of the parallel line is always equal, so as of the given condition if green and red lines are parallel then the slope of the red line is equal to the slope of the green line.
The slope of the red line = slope of the green line
The slope of red line = 5
Thus, the required slope of the red line is equal to 5, Option D is correct.

How would I find x and y????
Answer:
Y=17
X=17√2
Step-by-step explanation:
1) This triangle is a right isosceles triangle. You know this because it is marked in that way.
2) In an isosceles triangle, the legs are congruent. That means, if one leg is x, then the other leg will also be x.
- In this case, (y) will be 17 because the other leg is also 17.
3) According to pythagorean theorem, a^2 + b^2 = c^2. The hypotenuse is directly across the 90º angle. So, in this case, knowing that both legs are 17,
you can write 17^2 + 17^2 = c^2
(c = x) because i'm just substituting the values.
So now, solve it. You will get
289 + 289 = c^2
c^2 = 578
now just square root 578.
(remember c = x)
You get that x = √578 = 17√2

When Jonah babysits one hour, he earns $7.50.
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
The number of hours Jonah works depends on how much he earns.
Answer:
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
Step-by-step explanation:
When Jonah babysits one hour, he earns $7.50.
looking at the graph we see at 1 hour he earns 4 dollars false
The equation e = 4 h can be used to describe this situation.
The slope is 4 so y = 4x e = 4h would also work true
Jonah earns $20 to babysit for 5 hours.
Using our equation from above
e = 4*5 = 20 true
The number of hours Jonah works depends on how much he earns.
This would be false
The dependent variable is on the y axis. The amount he earns depends on how much he works

Nina sells bracelets for $3 each, necklaces for $5 each, and anklets for $4 each. She sells 8 bracelets, 24 necklaces, and 16 anklets. How much money does she make? *
Answer:
208 dollars
Step-by-step explanation:
necklaces- 24 x 5 = 120
bracelets- 8 x 3 = 24
anklets- 16 x 4 = 64
added together- 208
Nina makes a total of $208.
$208 money does she make.
Here, we have,
To calculate how much money Nina makes, we need to determine the total revenue from selling bracelets, necklaces, and anklets.
The revenue from selling bracelets can be calculated by multiplying the number of bracelets sold (8) by the price per bracelet ($3):
Revenue from bracelets = 8 * $3 = $24
The revenue from selling necklaces is found by multiplying the number of necklaces sold (24) by the price per necklace ($5):
Revenue from necklaces = 24 * $5 = $120
The revenue from selling anklets can be calculated by multiplying the number of anklets sold (16) by the price per anklet ($4):
Revenue from anklets = 16 * $4 = $64
To find the total revenue, we sum up the revenue from each type of item:
Total revenue = Revenue from bracelets + Revenue from necklaces + Revenue from anklets
Total revenue = $24 + $120 + $64 = $208
Therefore, Nina makes a total of $208.

Answer these questions about finding the missing angle measures. What is the measure of ∠Q? What is the measure of ∠T? What can be concluded about these triangles?
Answer:
<Q = 44.4
<T = 44.4
The triangles are similar
Step-by-step explanation:
Both triangle QSR and triangle TUV are similar triangles since the corresponding angles are equal.
Similar figuresTwo figures are similar if they have the same shape and the ratio of their corresponding sides are in the same proportion. Hence all the corresponding angles are similar.
From the diagram:
∠Q + ∠R + ∠S = 180° (angle in a triangle)
∠Q + 98 + 37.6 = 180
∠Q = 44.4°
∠T + ∠U + ∠V = 180° (angle in a triangle)
∠T + 98 + 37.6 = 180
∠T = 44.4°
Both triangle QSR and triangle TUV are similar triangles since the corresponding angles are equal.
