Answer:

Cost of bracelet = $1 and 35 cents

Step-by-step explanation:

Price before tax = $ 1.29

Tax Price = 5% of 1.29

              [tex]=\frac{5}{100} \times 1.29\\\\= 6.45 \times \frac{1}{100} \\\\= 0.0645[/tex]

Therefore price after tax = 1.29 + 0.06245 = 1.3545

Ans : cost of bracelet = $1 and 35 cents

Answer:

[tex]AD || BC[/tex]

Step-by-step explanation:

Required

What proves:

[tex]m\angle 2 = m\angle C[/tex]

[tex]m\angle 2[/tex] and [tex]m\angle C[/tex] are opposite [tex]angles[/tex] of the [tex]parallelogram.[/tex]

Also:

[tex]m\angle 2[/tex] is on [tex]AD[/tex] and [tex]m\angle C[/tex] is on [tex]BC[/tex]

So, for [tex]m\angle 2 = m\angle C[/tex] to be true [tex]AD || BC[/tex] must be true.

Answer:

y = -1x + 4

Step-by-step explanation:

Basically you would use the equation y=mx+b, then you would solve like that!

Answer:

[tex]P=24\: m[/tex]

[tex]A=41.52 \m^{2}[/tex]

Step-by-step explanation:

El perímetro de un hexágono se calcula de la siguiente manera:

[tex]P=6*l[/tex]

l es el lado del hexágono l = 4 m

Entonces P es:

[tex]P=6*4=24\: m[/tex]

El área del hexágono puede calcularse de la siguiente manera:

[tex]A=\frac{P*Ap}{2}[/tex]

P es el perímetro = 24 m

Ap es la apotema = 3.46 m

El Area sera:

[tex]A=\frac{24*3.46}{2}[/tex]

[tex]A=41.52 \m^{2}[/tex]

Espero te haya sido de ayuda!

Answer:

Step-by-step explanation:

I'm going to  assume you meant y = ab^x. If this is not correct, leave a comment.

x = 0

y = 7

7 = a * b^0

anything to the zero power is 1

y = a*b^0

y = a*1

7 = a

So far what you have is

y = 7 * b^x

Now let

x = 9

y = 3584  

3584 = 7 * b^9         Divide by 7

3584/7 = b^9

512 = b^9

If you knew how to use logs, that would be the surest way to do this question. However I'm going to make an assumption again and assume that you have not taken those yet.

So the easiest way is to find out what raised to the 9th power will equal 512

Could b = 5?

5^9 = 1 million 9 hundred thousand something. 5 is far too big. Make sure you understand why. 1 million is far greater than 512

So let's try b = 3

3^9 = 19 thousand which is still far too big. 19 thousand something is far larger than 512.

We have just one more number that we can try.

2^9 = 512 and we have it

Answer y = 7*2^x

Answer:

exponent of x is 33

exponent of y is 0

Step-by-step explanation:

you need to combine all powers (exponents) of x, and all exponents of y separately.

remember : x to the power of a divided by x to the power of b is x to the power of (a-b).

when multiplying, the "-" turns into a "+".

so, we have actually for x the exponent calculation :

8 - 14 -(-39) = 8 - 14 + 39 = 33

so, x³³ remains.

and for the y exponents

-26 -(-5) -(-21) = -26 + 5 + 21 = 0

so, all the y expressions eliminate each other and y⁰ remains.

Answer:

120$

Step-by-step explanation:

Equation

$= 10x + 50

x is the amount of hours.

Plug in for x

$ = 10(7) + 50

$ = 70 + 50

$ = 120

Answer:

70

Step-by-step explanation:

round 340 to 350 because 5 goes into 35,

7 times

then add the 0 to the end.

350 ÷ 5 = 70

Answer:

70

Step-by-step explanation:

round 340 to 350 because 5 goes into 35,

Answer:

you divide all the numbers so the triangle will be at -2.5x, 1x and 2y  and the rectangle is multiplied by 2 so 5x and 4y  

Step-by-step explanation:

Measure of angle w + measure of angle z = 180 degrees

Because they are linear pair.

Answer:

$67.22 each month

Step-by-step explanation:

Find how much Nick's grandparents will pay for by multiplying 4400 by 0.45:

4400(0.45)

= 1980

Subtract 1980 from 4400 to find how much Nick will have to save:

4400 - 1980

= 2420

Nick has 3 years to save for his tuition, meaning that he has 36 months to save (since there are 12 months in a year).

Find how much he has to save each month by dividing 2420 by 36:

2420/36

= 67.22

So, Nick will have to save approximately $67.22 each month

Answer:

the sum of (2x^2-8x) and (-x^2-2x )

=2x^2-x^2-8x-2x=x^2-10x

x ² - 10 x

Step-by-step explanation:

( 2 x ² - 8 x ) + ( - x² - 2 x )

2 x ² - 8 x - x ² - 2 x

2 x² - x ² - 8 x - 2 x ..(combine like terms)

x ² - 10 x

Answer:

Mary Lou is 14

George is 7

Kate is 6

Step-by-step explanation:

let G = George's age

let 2G = Mary Lou's age

let G-1 = Kate's age

G + 2G + G-1 = 27

4G = 28

G = 7

2G = 14

G-1 = 6
