Answer:

circumference=>2πr

circumference= 119.32 cm

π = 3.14

r =?

119.32 = 2 × 3.14 × r

r = 119.32/6.28

r = 19 cm

so area = πr²

area = 3.14 × (19)²

area = 3.14 × 361

area = 1,133.54 cm²

To make a specific hair dye, a hair stylist uses a ratio of 1 1/8 ounces of red tone, 3/4 ounces of gray tone, and 5/8 ounces of
natima [27]

Answer: To make 20 ounces of dye, we need 3 oz red tone, 6 oz of gray tone and 5 oz of brown tone.

To make 100 ounces of dye, we need 15 oz red tone, 30 oz of gray tone and 25 oz of brown tone.


Step-by-step explanation:

The amount of specific hair dye made by given ingredients=1\frac{1}{8}+\frac{3}{4}+\frac{5}{8}

=\frac{9}{8}+\frac{3}{4}+\frac{5}{8}

=\frac{9+6+5}{8}=\frac{20}{8}=\frac{5}{2}\ oz

Therefore , The amount of specific hair dye made by given ingredients=\frac{5}{2} qz

Multiply reciprocal of \frac{5}{2} to each ingredient to find the amount of each ingredient required to make 1 oz of specific hair dye.

To make 1 oz of specific dye, the amount of red tone needed=\frac{3}{8}\times\frac{2}{5}=\frac{3}{20}\ oz

Similarly, Gray tone=\frac{3}{4}\times\frac{2}{5}=\frac{3}{10}\ oz

Brown tone=\frac{5}{8}\times\frac{2}{5}=\frac{1}{4}\ oz

Now, multiply 20, to each

To make 20 oz of specific dye, the amount of red tone needed=\frac{3}{20}\times20=3\ oz

Similarly, Gray tone=\frac{3}{10}\times20=6\ oz

Brown tone=\frac{1}{4}\times20=5\ oz

To find each dye to make 100 ounces of dye, multiply 5 to the above amounts, [since 100=20\times5 ]

To make 20 oz of specific dye, the amount of red tone needed=15\ oz

Similarly, Gray tone=30\ oz

Brown tone=25\ oz

Plz help me thanks soo much and explain too :)
Yanka [14]

Answer:

f(0) = 14

Step-by-step explanation:

Given

f(x) = \left \{ {{|x - 8| + 6 \ x

Required

Find f(0)

From the piecewise function, we have the following as values of f(x):

f(x) = |x - 8| + 6

If x < 4

f(x) = 15

If x \ge 4\\

f(0) implies that x =0 and 0

So, we make use of the first function, which is:

f(x) = |x - 8| + 6

Substitute 0 for x in f(x) = |x - 8| + 6

f(0) = |0 - 8| + 6

f(0) = |- 8| + 6

|-8| = 8

So, the expression becomes

f(0) = 8 + 6

f(0) = 14

<em></em>

<em>Hence, the value of f(0) is 14</em>

Persia make a flower arrangement using the eight longest flowers which is the combined height of flowers Persia uses
andriy [413]

Answer:

Persia should measure the length of each flower that she used in creating this flower arrangement and add up all the values to get the total height (i.e., the combined height) of the eight flowers used. Make sure to keep the units consistent all throughout the calculation to avoid any errors. For example, if centimetres are used to measure height of one flower, use centimetres all throughout and not switch to using inches at any point.

Hope that answers the question, have a great day!

What value of y satisfies the system of equations below?<br> 2x - y = 6<br> 2x + 3y = 14
Oksana_A [137]

Answer: y=2

Step-by-step explanation:

2x+3y=14 - 2x-y=6 = 4y=8

y=2

If you need x, just insert y into the equation and work out x from there

2x-2=6

2x=8

x=4
