Find the perimeter of a regular hexagon with a side of 8 meters

Answer: 36%; yes, the % change is equal to the percent discount

Step-by-step explanation:

Initial price = $69.99

Final price = $44.99

change in price = |(final - initial)|

change in price = |(44.99 - 69.99)|

change in price = $25

25/69.99 = x/100

100(25/69.99) = x

100(0.357) = x

35.7% = x

x = 36%

Answer:

30 and 9

Step-by-step explanation:

x+y=39 , x-y=21

Solve for x:

x+y=39 , x-y=21

x= 30

Substitute x with 30:

(30)+y=39 , (30)-y=21

Solve for y:

y=9

Answer:

25) x = 18 26) x = 50

Step-by-step explanation:

25) 108 + 4x = 180

108 + 4x = 180

-108           -108

4x = 72

x = 18

26)

101 + (x + 29) = 180

101 + 29 + x = 180

130 + x = 180

-130        -130

x = 50

Answer: C.

f(t) = P(1.02)4t

Step-by-step explanation:

f(t) = P(1.02)4t will have the greatest compound interest because the interest is on quarterly bases with an increment of 1.02 and the rate of 8%

Note : 8/100 × 1/4 = 0.02

There is no increment in D and A is yearly based. Option C is for 6 month.

i took the test and got it right so... and do you have Mr. Hoffman

The sum of the first six terms of the following sequence is ∑(from i=1 to 6) (-10 - 3(i-1)), the correct option is A.

Lets suppose its initial term is f=a , multiplication factor is  r

and let it has total n terms, then, its sum of a geometric sequence is given as:

[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]

(sum till nth term)

We are given that;

The sequence;  −10, −13, −16, …

Now,

The given sequence is an arithmetic sequence with first term (a1) = -10 and common difference (d) = -3.

Using this formula, we can find the first six terms of the sequence as follows:

a1 = -10

a2 = -10 + (-3) = -13

a3 = -10 + 2(-3) = -16

a4 = -10 + 3(-3) = -19

a5 = -10 + 4(-3) = -22

a6 = -10 + 5(-3) = -25

We can represent the sum of the first six terms using sigma notation as:

∑(from i=1 to 6) ai = (-10) + (-13) + (-16) + (-19) + (-22) + (-25) = -105

The sum of the first six terms of the given sequence is -105.

Using sigma notation, we can write this as:

∑(from i=1 to 6) (-10 - 3(i-1)) = -105

Therefore, by the geometric sequence the answer will be ∑(from i=1 to 6) (-10 - 3(i-1)).

Given b equals -3, determine if it is a solution to 4b - 6 = - 18.

So, we have our given which is b = -3, and we are asked to determine if it a solution to the above equation.

To do this, we can plug -3 in for b and see if it works out.

Work:

Plug in -3 for b.

4(-3) - 6 = - 18

-12 - 6 = -18

-12 - 6 = - 18

Thus, b = -3 is a viable solution for the equation of 4b - 6 = -18.

First we, Subtract the 16 from 2x ( which we can't do) so we change the equation to 16 - 2x = 4y

Second we, solve for x.  x = −2y + 8, We divide both sides by 2,

-2y/-2= y ( The two -2s cancle each other ) 8/2= 4

x = 4

Next we, solve for y. y = 4 −x/2y, we multiply both sides by 2y,

4 * 2y = 8y ( LOL ) -x/2y * 2y = -x

NOW WE have 8y - x

Answer:

x=6√3

y=12√3

Step-by-step explanation:

This is a 30 60 90 triangle.

The side opposite from the angle 60 is x√3, which makes 18=x√3, which eventually solves to x=6√3

The side opposite from the 90 degree angle is 2x, so multiply 6√3 by 2, which is 12√3, making y equal 12√3

Answer:

Four less than a unknown variable- C) y-4

Quotient of a variable and four- E) z÷4

some number to the power of four- B) a^4

Four times an unknown value- D) 4x

Four more than some number- A) B+4

Step-by-step explanation:

The final answers are:

Four less than an unknown value            C) y-4

Quotient of a variable and four                E) Z/4

Some number to the power of four         B) a⁴

Four times an unknown value                  D) 4x

Four more than some number                 C) b+4

An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.

Let's analyze each statement separately:

- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling  the unknown value, it means we have to write y-4

- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling  the unknown variable, it means we have to write

z/4

- Some number to the power of four --> this means that we have to write the power of a number, in the form , where m in this case is equal to 4. Calling  the unknown number, it means we have to write a⁴

- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling  our unknown values, we have to write 4x

- Four more than some number --> this means we have to add 4 to an unknown number. Calling  the unknown number, it means we have to write b + 4
