36^{2} + 18^{2} = c^{2}... A squared + B squared = C squared
1296 + 324 = c^{2}... square 36 and 18
1620 = c^{2}... combine like terms
40.25... square root 1620 to get final answer- 40.25 m

Samantha has 54 beads. Amanda has twice as many beads as Samantha. They are making bracelets it takes 8 beads to make a bracelet

wlad13 [49]

Answer:

On combining the beads they can make 20 bracelets.

Step-by-step explanation:

The number of beads Samantha has = 54 beads

Number of beads Amanda has = 2 x( Number of beads Samantha has)

= 2 x 54 = 108 beads

The total number of beads Amanda and Samantha has

= 54 beads + 108 beads

= 162 beads

Number of beads required to make 1 bracelet = 8 beads

Now, $\textrm{The number of bracelets made} = \frac{\textrm{Total number of beads they both have}}{\textrm{Beads required to make 1 bracelet}}$

= $\frac{162}{8} = 20.25$ ≈ 20

or, the total number of bracelets they can make is 20.

Hence, on combining the beads they can make 20 bracelets .

Determine whether these two functions are inverses.

11Alexandr11 [23.1K]

Answer:

No The reactions are not inverses to each other

Step-by-step explanation:

f(x) = 3x + 27

Let f(x) be y

y= 3x+27

subtracting 27 on both sides

3x = y - 27

x= (y-27)/3

= y/3 - 9

inverse function is x/3 -9 not x/3 + 9

Therefore, not an inverse

Hisako sells dolls at her doll store. If she sells a doll for $35, and there is 6% sales tax, what is the tax amount a customer

Sloan [31]

Given:

The price of a doll = $35

Sales tax = 6%

To find:

The tax amount that a customer will pay on one doll.

Solution:

The price of doll is $35 and the sales tax is 6%, so the tax amount on a doll is 6% of 35.

$\text{Tax amount}=35\times \dfrac{6}{100}$

$\text{Tax amount}=\dfrac{210}{100}$

$\text{Tax amount}=\dfrac{21}{10}$

$\text{Tax amount}=2.1$

Therefore, the tax amount that a customer will pay on one doll is $2.1.
