The price of a skateboard was reduced from $150 to $90. By what percentage was the price of the skateboard reduced?
Answer:
40%
Step-by-step explanation:
Ignore the zeros, then think about the 15 ‘s multiplication table. Once you do, you will find that 90 is 15 times 6, which is 60%. And 100-60 is obviously 40. Hope this helps.
The percentage that was reduced from the original price is 40 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The original price of the skateboard = $ 150
The reduced price of the skateboard = $ 90
The difference between the original price and reduced price =
Original price of the skateboard - Reduced price of the skateboard
The difference between the original price and reduced price = 150 - 90
= $ 60
Let the percentage decrease be A
Now the equation will be
Original price of the skateboard - A % ( Original price of the skateboard ) =
Reduced price of the skateboard
So ,
150 - A/100 ( 150 ) = 90
Adding A/100 ( 150 ) on both sides , we get
A/100 ( 150 ) + 90 = 150
Subtracting 90 on both sides , we get
A/100 ( 150 ) = 60
Multiply by 100 on both sides , we get
150A = 6000
Divide by 150 on both sides , we get
A = 40 %
Hence , the percentage at which the price of the skateboard reduced is 40%

Step-by-step explanation:
A licensed nurse practitioner is instructed to give a patient 1500 milligrams of an antibiotic over a period of 36 hours. If the antibiotic is to be given every 2 hours starting immediately, how much antibiotic should be given in each dose? To answer this question, solve the equation 18x=1500.
Answer:
83.33 milligrams
Step-by-step explanation:
The equation, [tex] 18x = 1500 [/tex] represents the total dosage of antibiotics to be given to the patient in relation to the hours.
Thus, the each dosage = x.
Let's solve for x
[tex] 18x = 1500 [/tex]
Divide both sides by 18
[tex] \frac{18x}{18} = \frac{1500}{18} [/tex]
[tex] x = 83.33 milligrams [/tex] (nearest hundredth)

Select all of the statements that are true for the given parabola.
Answer:
A and B are true
Step-by-step explanation:
The minimum is the turning point on the graph and occurs at (1, - 2)
The x- intercepts are where the graph crosses the x- axis , that is at
x = - 1 and x = 3 or in coordinate form (- 1, 0 ) and (3, 0 )
The equation of the axis of symmetry is a vertical line passing through (1, - 2)
with equation x = 1
The true statements are A and B
Answer:
⇨ A and B choice
Step-by-step explanation:
⟺ Consider all choices.
⥱ Choice A is correct because It's upward Parabola ( a > 0) where there is only the minimum point/value. The minimum point is at (1,-2). The vertex for upward parabola can be called the minimum point.
⥱ Choice B is correct because the Parabola intercepts x-axis at (-1,0) and (3,0) from the graph.
⥱ Choice C is wrong because the Axis of Symmetry is supposed to be x-term/value for the Parabola. If it is the y-value/term then it would be Side Parabola.
⥱ Choice D is wrong because an upward Parabola doesn't have the maximum point. The only Parabola with maximum point is downward Parabola ( a < 0)

Step-by-step explanation: open circle, with crocodile sign pointing to right which means u have to go left! Have a nice day!!
Answer:
C) a number line going from negative 6.5 to negative 5.8. An open circle is at negative 6.1. Everything to the left of the circle is shaded.
Step-by-step explanation:
Open circle means < or >
Closed circle means < or >
So has to be an open circle since the sign is <. it also says w < -6.1
so w has to be less than -6.1. So less than -6.1 would be -6.2, -6.3, -6.4etc.

El número misterioso: soy múltiplo de 3 y de 4 y estoy comprendido entre 30 y 99. El resto de mi división por 5 es 4. ¿Quién soy?
Answer:
84
Step-by-step explanation:
Let the number be x.
As the number is multiple of 3 and 4, so the number must be a multiple of the lowest common factor (LCM) of 3 and 4.
LCM(3,4)=12
So, the number, x, is a multiple of 12.
All the numbers between 30 and 99, which are multiples of 12 are 36, 48, 60, 72, 84, 96.
When x is divided by 5, the remainder is 4, so the unit digit of the number is 4.
Now, the number between 30 and 99, which is multiple of 12 and having the unit digit 4 is 84.
Hence, the required number is 84.
Percy has already walked 25 kilometers this week, plus he plans to walk 5 kilometers during
each trip to school. After 12 trips to school, how many kilometers will Percy have walked in
total?
Answer:
85
Step-by-step explanation:
He walked 25 already. So you have x=25. He walks 5 km during each trip. There are 12 trips. 5 times 12 is 60. x=25+60. So, 25 plus 60 is 85.

Help ASAP. Solve both
Step-by-step explanation:
question 15
For y to be parallel to z the sum of given angles must be equal to 180°
3x + 7 + 10x - 22 = 180° add like terms
13x - 15 = 180 add 15 to both sides
13x = 195 divide both sides by 13
x = 15
question 16
If y is parallel to z then the given angles are alternate exterior and has same measurement
11x - 3 = 4x + 39
11x - 4x = 39 + 3
7x = 42 divide both sides by 7
x = 6
