O bicicleta costa 420 de lei. Pretul ei se reduce cu 15%. Cat va costa bicicleta dupa reducere.
Answer:
The price of the bicycle after the discount is 357 lei
Step-by-step explanation:
The given question says, "The bicycle costs 420 lei. Its price is reduced by 15%. How much will the bike cost after the discount."
Cost price of the bicycle = 420 lei
Discount = 15%
We need to find the price of the bicycle after the discount. It can be calculated as follows :
[tex]P=420\times \dfrac{15}{100}\\\\=63[/tex]
Price = 420 -63
= 357 lei
Hence, the price of the bicycle after the discount is 357 lei.

Below, enter x If the graph of the given equation is symmetric with respect to the x-axis, y if it is symmetric with respect to the y axis, o (lower
case O) if it is symmetric with respect to the origin, and n (for None) if it has none of these three symmetries.
y=xt
y = x2 +1
y=x²+x
y = (1 + x2)3
Answer:
Step-by-step explanation:
You can tell by looking at the form of each equation.
y = tx
This is a straight line that passes through the origin, so it symmetric with respect to the origin.
y = x²+1
This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.
y = x²+x = (x+½)² - ¼
This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.

Cos pie divided by 12 in surd form
Answer:
¼(√6 + √2)
Step-by-step explanation:
We want to find cos (π/12) in surd form.
Now, cos (π/12) can be expressed as;
cos [(π/4) - (π/6)]
Now, from trig derivations we know that;
Cos (A - B) = CosACosB + sinAsinB
Thus;
cos [(π/4) - (π/6)] = cos(π/4)Cos(π/6) + sin(π/4)sin(π/6)
Now, in surd form;
cos(π/4) = sin(π/4) = (√2)/2
Cos(π/6) = (√3)/2
sin(π/6) = 1/2
Thus, Plugging in relevant values to get;
cos(π/4)Cos(π/6) + sin(π/4)sin(π/6) = ((√2)/2 × (√3)/2) + ((√2)/2 × 1/2)
This gives;
((√6)/4) + ((√2)/4) = ¼(√6 + √2)

A cone has a volume of 33 cubic inches. If a cylinder has the same height and the same radius as the cone, what is the volume of the cylinder?
Answer:
C
Step-by-step explanation:
Step-by-step explanation:
The volume of a cylinder = πr²h
= 33 cubic inches
The volume of a cone = ¹/3 πr²h
If the cylinder and come share the same radius and height then ‘πr²h’ part of the formulas is the same for both;
It means the difference in proportionality is ¹/3 (because even π is the same across board). The volume of the cone is therefore;
¹/3 (33)
= 11
= 11 cubic inches

How many degrees are there in the "Department Store" angle? *
How many degrees are there in the "Gas Station" angle? *
Answer:
Department Store:
7(18.75)+8= 139.25
Gas Station:
18.75+22= 40.75
Step-by-step explanation:
The mistake is 7x+8+x+22 should not equal 90. It should equal 180 degrees because the two angles are supplementary angles. (It forms a straight line)
Correct equation and how to solve for X:
7x+8+x+22=180
8x+30= 180
8x= 150
x=18.75
Department Store:
7(18.75)+8= 139.25
Gas Station:
18.75+22= 40.75

Step-by-step explanation:
Solve pls (correctly) brainliest if correct! I, lots of points!
Answer:
5
Step-by-step explanation:
First, find the equation of the line:
put it in the form y = mx + b where m is the slope and b is the y-intercept
You already have m = 2, so y = 2x + b.
Then, since you know (1, 3) is a solution so you can plug x = 1 and y = 3 into the equation to find out what b is.
3 = 2 * 1 + b
3 = 2 + b
1 = b
This means the equation of the line is y = 2x + 1.
Then, since you're trying to find out what y is when x = 2, you can plug in x = 2 into the equation:
y = 2 * 2 + 1
y = 4 + 1
y = 5

A cookie recipe calls for 1.5 teaspoons of vanilla for one batch. How many teaspoons of vanilla would be needed for 2.5 batches of cookies?
Answer:
3.75
Step-by-step explanation:
it said 2.5 batches to you need to 1.5x2 = 3 15 divided by 2 = .75
3.75
3.75 teaspoons of vanilla will be needed for 2.5 batches of cookies. If it requires 1.5 teaspoons of vanilla for one batch.
The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
Given,
It requires 1.5 teaspoons of vanilla for one batch which can be interpreted as 1 batches of cookies requires 1.5 teaspoons of vanilla.
1 batches----->1.5 teaspoons of vanilla
Using unitary method,
To calculate the number of teaspoons of vanilla needed for 2.5 batch is as follows:
1 batches----->1.5 teaspoons of vanilla
Multiply 2.5 both sides.
(1 batches)X 2.5----->(1.5 teaspoons of vanilla)X 2.5
2.5 batches----->3.75 teaspoons of vanilla
3.75 teaspoons of vanilla will be needed for 2.5 batches of cookies

Solve by substitution or elimination
4X – 3y = 7
4x + y = 11
Answer:
(5/2 , 1)
Step-by-step explanation:
4X – 3y = 7
4x + y = 11
———————
Multiply a -1 to the bottom equation to get the 4x as a negative so it cancels out.
4x - 3y = 7
-4x - y = -11
——————
-4y = -4
Divide by -4
y = 1
Substitute the value of y into one of the equations and solve
4x - 3(1) = 7
4x -3 = 7
4x = 10
Divide by 4
X = 10/4
Simplify by dividing by 2
x = 5/2
Therefore the answer is (5/2, 1 )
