Answer:

For y=0.1 the value is a prime number.

Step-by-step explanation:

Given:

y=0.4

10y + 2 is an even number.

We need to find the value of y for which value of equation is prime number.

Solution:

Let us assume that y=0.1

Substituting the value in given equation we get;

10y+2\\\\=10\times 0.1+2\\\\=1+2\\\\=3

Which is  a prime number.

Hence We can say that for y=0.1 the value is a prime number.

suter [353]
Linda should use ...
  15 gallons of 80% juice
  5 gallons of 60% juice

_____
Let g represent the number of gallons of 80% juice needed. Then (20-g) is the number of gallons of 60% juice Linda will use. The amount of juice in the mixture can be written as
  0.80g +0.60(20 -g) = 0.75×20
  0.20g = 20(0.75 -0.60) = 20×0.15
  g = 20×0.15/0.20 = 15
The amount of 80% juice needed is 15 gallons, so 5 gallons of 60% juice are needed.

lozanna [386]

Answer:

Guo Qi requires 75 days to watch videos on Khan Academy.

Step-by-step explanation:

We are given the following in the question:

Number of videos watched by Guo Qi each day = 15
