A painter uses 2 tubes of blue paint for every 6 tubes of white paint to paint a mural. At that rate ,How many tubes of blue pai
Jlenok [28]

Answer:

5 tubes of blue paint are used for 15 tubes of white paint.

Step-by-step explanation:

Given:

To paint a mural painter uses 2 tubes of blue paint for every 6 tubes of white paint

Hence,

6 tubes of white paint = 2 tubes of blue paint

Now we need to find number of blue paint tubes used for 15 tubes of white paint.

6 tubes of white paint = 2 tubes of blue paint

15 tubes of white paint = number of blue paint tubes used for 15 tubes of white paint

Hence we will used unitary method to find the same;

Number of blue paint tubes used = \frac{15\times 2}{6} = \frac{30}{6}=5

Hence 5 tubes of blue paint are used for 15 tubes of white paint.

Need help ........................
natima [27]

Answer:

m=0.833333

Step-by-step explanation:

(1/16)−3m+1=64

log((1/16)−3m+1)=log(64)

(Take log of both sides)

(−3m+1)*(log(1/16))=log(64)

−3m+1=log(64)

log(1/16)

−3m+1=−1.5

−3m+1−1=−1.5−1

(Subtract 1 from both sides)

−3m=−2.5

−3m

−3

=

−2.5

−3

(Divide both sides by -3)
