Denise mixed 1 4/5 ounces of blue paint with 2 1/10 ounces of yellow paint. How many ounces of paint did Denise mix?
fenix001 [56]

Answer:

Hence total 3.9 ounces of paint was used to make the mixture.

Step-by-step explanation:

Denise mixed 1\frac{4}{5} ounces of blue paint with 2\frac{1}{10} ounces of yellow paint.

Now we are asked to find  how many ounces of paint did Denise mix.

i.e. we are asked to find the total number of paint used to form the mixture.

We know that:

 1\frac{4}{5}=\dfrac{9}{5} and 2\frac{1}{10}=\dfrac{21}{10}

Hence total paint used= \dfrac{9}{5}+\dfrac{21}{10}

                                   =\dfrac{39}{10}=3.9

Hence total 3.9 ounces of paint was used to make the mixture.

Julio considers the reduction of the triangle. What is the correct cross product that he should use to solve for the missing dim
Talja [164]

Answer:

(8)(21) = 12x

Step-by-step explanation:

(8)(12) = 21x

(8)(21) = 12x

(12)(8) = 12x

(12)(21) = 8x

Opposite : Adjacent

12 in : 21 in

Opposite : Adjacent

8 in : x in

Equate both ratios to solve for x

12 : 21 = 8 : x

12 / 21 = 8 / x

Cross product

(12)(x) = (21)(8)

12x = 168

x = 168 / 12

= 14

x = 14
