An item is regularly priced at $75 It is now priced at a discount of 60% off the regular price. What is the price now?
Answer:
Price is $ 30
Step-by-step explanation:
Regular price = $75
Discount = 60%
First we find the 60% of 75
( 75 × 60 ) ÷ 100 = 45
Now this answer with regular price
75 - 45 = 30
MARK BRAINLIEST IF YOU UNDERSTAND
Answer:
$ 30
Step-by-step explanation:
Regular price ⇒ $ 75
Discount ⇒ 60% off the regular price
First let us find the discount that they will give.
Let us solve now.
75 × 60% = $45
And now let us find the new price of the item.
For that you have to subtract the discount by the regular price.
New price = Regular price - Discount
= $ 75 - $ 45
= $ 30
Hope this helps you :-)

What are similar triangles?
Similar triangles are two triangles that, while not sharing the same size, have the same proportions and angles measurements. Their corresponding angles are equal and the corresponding sides are in the same ratio.
Triangle PQR is similar to triangle STU because their angles are the same, and they share the same proportions in regards to their side lengths.
To find the unknown side of a similar triangle, set up two ratios equal to each other that represent the ratios of each triangle.
n is the hypothenuse of triangle PQR, so in your ratio, n should be in a fraction with 13, the hypothenuse length of triangle STU.
The fraction that n and 13 will be set equal to should also be the same side of the different triangle. (so either both of them are the shortest legs or both of them are the longest legs of their triangles)
Let's check each answer:
n is in the denominator and 13 is in the numerator. Great! 36 is the longest leg of triangle PQR and 12 is the longest leg in triangle STU, great! This choice is wrong, however. This is because both denominators and numerators should be set equal to their respective triangles. n is in triangle PQR, while 12 is in triangle STU, so they can not be set equal to each other.15 and 5 are both the shortest legs in their triangles, great! Unfortunately, 12 and n are both not hypothenuses, so this answer is incorrect. 15 and 5 are both the shortest legs in their respective triangles, but, again, n and 12 are not both hypothenuses.n is in the denominator and 13 is in the numerator. Great! 36 is the longest leg of triangle PQR and 12 is the longest leg in triangle STU, great! And, n is set equal to 36 (they are in the same triangle) and 13 is set equal to 12 (they are in the same triangle). This is the correct answer.*To check if your answer is correct, solve for n by cross multiplication and plug in your answer into the fraction. Both sides should simplify to the same fraction*

Emir is standing in a treehouse and looking down at a swingset in the yard next door. The angle of depression from Emir's eyeline to the swing set is 31. 43°, and Emir is 11 feet from the ground. How many feet is the base of the tree from the swingset? Round your answer to the nearest foot. 15 feet 20 feet 18 feet 24 feet.
Tangent is the ratio of perpendicular to the base. The distance between the base of the tree and the swing set is 18 feet.
What is Tangent(Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm{Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
Base is the adjacent smaller side of the angle θ.
As it is given that the height of the tree is 11 feet, while the angle of depression is 31.43°, therefore, the tangent can be written as,
[tex]\rm{Tangent(31.43^o) = \dfrac{AB}{BC}[/tex]
Where BC is the length between the base of the tree and the AB is the height of the tree.
[tex]\rm Tangent(31.43^o) = \dfrac{11}{BC}\\\\BC = 17.999 \approx 18[/tex]
Hence, the distance between the base of the tree and the swing set is 18 feet.

help me find x and y please
Answer:
Step-by-step explanation:
4 angles in a quadrilateral (sorry if i spelled that wrong) add up to 360
So we have : 11x+4 + 5y +5 +5x + 13y - 5 = 360
Then, we simplify as 16x + 4 + 18y = 360
=> 16x + 18y = 356
Divide both side by 2
8x + 9y = 178
So, x is a multiple of 8 and y is a multiple of 9
Then if we keep replacing, you will eventually come to an answer of y = 10 and x = 11
Hope it helps :)

inches per hour? Justify your answer.
Interval, 1 a.m. to 12 noon has the greater rate of snowfall, in inches per hour.
What is interval?First step
1am - 12 noon will gives us 11 hours
6am - 3pm will gives us 9 hours
Second step
Inches per hour for 11 hours
=33-1/11
=32/11
=2.91 inches per hour
Inches per hour for 9 hours
=36-11/9
=25/11
