Answer:
[tex]\frac{i\times d}{100}[/tex]
Step-by-step explanation:
To calculate the discount, we multiply the initial amount (i) to the discount (d) and then divide that answer by 100. After we find that answer we then subtract it from the initial price.
For example:
A computer costs $695 and it has a 7% discount. Calculate the total costs of the computer after the 7% discount.
[tex]\frac{695\times7}{100} =695\times7=4865\div100=48.65[/tex]
[tex]695-48.65=646.35[/tex]
[tex]c=646.35[/tex]
The computer (after a 7% discount) costs "$646.35 dollars."
Hope this helps.

Which interval, 1 a.m. to 12 noon or 6 a.m. to 3 p.m., has the greater rate of snowfall, in
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
=2.27 inches per hour
Therefore based on the above analysis Interval, 1 a.m. to 12 noon has the greater rate of snowfall, in inches per hour.

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

what is 4 times b = 14
Answer:
b=3.5
Step-by-step explanation:
Answer:
3.5x-1
Step-by-step explanation:
Solving:
4bx = 14
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Divide each side by '4x'.
b = 3.5x-1
Simplifying
b = 3.5x-1
The Bake Stars need to arrange 718 pupcakes on trays for a pooch pool party.
If each tray can hold 9 pupcakes, about how many trays will the bakery need?
Choose the best estimate.
1) 4
2) 20
3) 60
4)40
3) 60
Step-by-step explanation:
718 ÷ 9 = 79.78
So, if you round to the nearest whole number its about 80, the closest answer from your options is 60 so I think the best estimate is number three: 60.

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.

What is the equation of the line that passes through the point (-2, 1) and has a
slope of -5/2?
Answer:
y = -5/2x - 4
Step-by-step explanation:
When given a point and a slope, we use slope-intercept formula:
y - y1 = m (x - x1)
m = slope point: (-2,1)
y - y1 = m (x - x1)
y - 1 = -5/2 (x - (-2))
y -1 = -5/2x - 5
+ 1 + 1
y = -5/2x - 4

Write the point slope form of the equation of the line through the given points: (-4,-1) and (-3,1)
PLEASE EXPLAIN. STEP BY STEP INSTRUCTIONS
Step-by-step explanation:
the general point-slope form is
y - y1 = m(x - x1)
with (x1, y1) being a point on the line, and m being the slope (the incline of the line).
we have the point. we can pick one from the 2 choices, I typical go for the one with smaller values. so, I will use (-3, 1).
now we need to calculate the slope.
the slope is the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.
so, for our 2 points we see
x changes by +1 (from -4 to -3).
y changes by +2 (from -1 to +1).
and the slope is +2/+1 = 2
therefore our equation is
y - 1 = 2(x - -3)
or simplified
y - 1 = 2(x + 3)

QUESTION IN PIC- 20 POINTS :)
Answer:
CD = 3 -√3
Step-by-step explanation:
The ratio of leg lengths in a 30°-60°-90° triangle is ...
1 : √3 : 2
The longest leg of ΔABD is 2√3, so we must multiply all of these ratio values by √3 to see the actual lengths of the triangle sides.
AB : BD : AD = 1 : √3 : 2 = √3 : 3 : 2√3
That is ...
AB = √3
BD = 3
__
The lengths of the legs in isosceles right triangle ABC are the same, so ...
BC = AB = √3
Then the length of interest is ...
CD = BD -BC
CD = 3 -√3 . . . . . . . a=3, b=-1

Answer: Intercept Form
Step-by-step explanation:
There are three methods for determining the minimum value of a quadratic equation. Each of them can be useful in determining the minimum. The first way is by using a graph. You can find the minimum value visually by graphing the equation and finding the minimum point on the graph. The y-value of the vertex of the graph will be the minimum. This is especially easy when you have a graphing calculator that can do most of the work for you.

Step-by-step explanation:
Everything starts of at 100% and the rate of interest is 9.5% so we add them on=109.5%
Now we want this percentage as a decimal so we divide by 100 = 1.095 this our multiplier
Then get the original amount that you borrowed = 6000 times by the multipler=1.095 to the power of number of years so
6000 multipled by 1.095 to the power of 5
