The price of a skateboard was reduced from $150 to $90. By what percentage was the price of the skateboard reduced?

Answer:

850x = y

Step-by-step explanation:

6=a/(4+2)

6=a/6

Now multiply both sides by 6 to cancel one of them.

6*6=6*a/6

6*6=a

36=a

Step-by-step explanation:

the only reason you would need help with this is, if you don't understand what exponents are and how they work.

because once you understand that, you can do the whole question in 30 seconds yourself. way faster than the posting here and then copying answers back into your system.

so, let me explain this important element :

when you have something like 5³, then this 3 is the exponent, and the 5 is the base.

when we talk about such a thing we typically say "5 to the power of 3".

now what did it mean ?

well, it is a multiplication. a multiplication of the base by itself (like when we square a number).

and the exponent tells is how often the base is multiplied by itself.

so, back to my example :

5³ = 5×5×5

3² = 3×3

13⁴ = 13×13×13×13

once you understand that, you can solve the question yourself in seconds.

e.g. the first is looking for the equivalent of 7⁴.

we need to find the answer option that dissolves this like the examples above to 7×7×7×7.

and we find B to be the right answer.

for 3⁶ = 3×3×3×3×3×3

and E is right. and so on.

answer. X=50

as..

draw a imaginary line between M

let it one side be y and z

y+z=120

now,

y=70(being alternate angle)

y+z =120

so

z=120-70

z=50

as we know,

z is alternate to X

so ,X=50

first term: t₁

t₁ = 10

t₂ = t₁ * (1+1) = 10 * 2 = 20

t₃ = t₂ * (2+1) = 20 * 3 = 60

t₄ = t₃ * (3+1) = 60 * 4 = 240

The  IUPAC name for a binary covalent compound lack prefixes such as mono, di, tri tetra etc.

A binary compound is a compound that is composed of only two elements. Many binary compounds could be made up of a metal and a nonmetal or even two nonmetals as the case may be. Examples of binary compounds include; SO2, NaH, K2S etc.

We must note that a binary covalent compound uses Roman numerals to indicate the oxidation state of the central atom in the compound. For instance, SO2 is called Sulfur IV oxide.

Hence, the  IUPAC name for a binary covalent compound lack prefixes such as mono, di, tri tetra etc.

Answer:

30-60-90 is a special right triangle

if the side opposite to the 30 degree angle = x,

then the side opposite to the 90 degree angle = 2x

and the side opposite to the 60 degree angle = x*sqr3

2x=14

x=7

side BC is opposite to the 30 degree angle, so it is 7 cm

side AB is opposite to the 60 degree angle, so it is 7sqr3 cm

Answer:

Step-by-step explanation:

In each case, solve for y. You do this by getting the y-term by itself, then dividing by the coefficient of y.

  -3y = -4x +12 . . . . . subtract 4x

  y = 4/3x -4 . . . . . . . divide by -3

The slope is 4/3; the y-intercept is -4.

__

  y = 3x -6 . . . . . . divide by 2

The slope is 3; the y-intercept is -6.

Additional comment

Whatever you do to one side of the equation, you must also do to the other side. When we say "subtract 4x", that means 4x is subtracted from both sides of the equation. The reason for doing that in the first equation is to eliminate the 4x term from the left side.

(Sometimes, you may see operations described as "move ...". There is no property of equality called "move." There are addition, subtraction, multiplication, division, and substitution properties of equality. Any equation solving process will make use of one or more of these.)

Where P is the principal, R is the rate of interest, and T is the time.

Mr. Miranda acquired $8,800 for a considerable length of time at basic interest to pay for another pool. On the off chance that Mr. Miranda paid the bank a sum of $10,287.20.

The simple interest rate of the loan will be given as,

10,287.20 = 8,800 + [(8,800 x r x 12) / (100 x 12)]

1,487.2 x 100 = 88r

r = (1487.2 / 88) x 100

r = 0.169 x 100

r = 16.9%

The simple interest rate of the loan will be 16.9%. Then the correct option is C.
