If the circumference is 78.1 inches what is the diameter rounded to the nearest 10th

Mathematics

Answer:

The diameter of the circle is 24.9 in

Step-by-step explanation:

To solve this exercise we need to use the circumference formula of a circle and clear d:

c = circumference = 78.1 in

d = diameter

π = 3.14

c = π * d

d = c / π

we replace the known values

d = 78.1 in / 3.14

d = 24.8726 in

round to the nearest tenth

d = 24.8726 in = 24.9 in

The diameter of the circle is 24.9 in

The recipe for Perfect Purple Water says, "Mix 8 ml of blue water with 3 ml of red water." Jada mixes 24 ml of blue water with 9
cluponka [151]

Answer:Jada will get same shade as Perfect Purple Water

Step-by-step explanation:

STEP 1

To get the right  recipe for Perfect purple water, every new mixture must have an equivalent ratio as the ideal mixture

The ideal mixture is given as

8ml  blue water and 3 ml red water.

Step 2

Andre mixes 16ml blue water with 9ml red water

\frac{8ml}{3ml} is not equivalent to \frac{16ml}{9ml}

Because dividing Andre's mixture  by a common value  will  not give  the equivalent ratio of the ideal recipe

\frac{16ml}{9ml}  \frac{/}{/}  \frac{3}{3} =\frac{5.3ml}{3ml}  

Jada mixes 24ml blue water with 9ml red water

\frac{8ml}{3ml} is equivalent to \frac{24ml}{9ml}

Because dividing Jada's mixture  by a common value  gives the equivalent ratio of the ideal recipe

\frac{24ml}{9ml}  \frac{/}{/}  \frac{3}{3} =\frac{8ml}{3ml}  

This shows that Jada got the right recipe and will get  same shade as Perfect Purple Water but in a higher quantity, 3 times the right recipe for  Perfect Purple Water
