Find how X and y compare when log X = 6.6 and log y = 3.6
asambeis [7]

Answer

x = 3981071.7055

y  = 3981.0717

x > y

Step by step explanation

First let's find the value of x and y by taking anti - log.

log X = 6.6

X = log^ -1 (6.6)

X = 3981071.7055

Similarly,

log Y = 3.6

Y = log ^(-1) 3.6

Y = 3981.0717


Once we found the values of X and Y , we can easily compare them.

Here x > y

Hope you will understand the concept.

Thank you. :)

A fair spinner has 10 equal sections: 3 red, 3 blue and 4 green. It is spun twice. What is the probability of getting not green
Nonamiya [84]

Answer:

0.24

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome. The probability that an even will happen or not happen is 1.

Given that the spun has 10 sections 3 red, 3 blue and 4 green, the probability of not getting green

= (3 + 3)/(3 + 3 + 4)

= 6/10

The probability of getting green

= 4/10

Hence the probability of getting not green then green

= 6/10 * 4/10

= 24/100

= 0.24

A father is 38 years old. his sons are 13 and 5 years old, and his daughter is 8 years old. In how many years will the father be
nalin [4]

Answer:

6 years

Step-by-step explanation:

So each person's age can be represented as a linear equation, since each year our age increases by 1. It can be represented in the slope-intercept form: y=mx+b. The slope in this case is going to be 1, since the time is going to be years, and each year everyone's age goes up by 1 (of course if you're still alive...) and y-intercept in this case represents their current age.

So the father can be represented as: y=x+38

The sons can be represented as: y = x+13 and y=x+5

The daughter can be represented as: y=x+8

So adding up all his children you get:

(x+13)+(x+5)+(x+8)

This gives you the equation:

3x+26

Now set this equal to the father's age to solve for x (in this context it's years)

3x+26=x+38

Subtract from both sides

2x+26=38

Subtract 26 from both sides

2x=12

Divide both sides by 2

x=6

So in 6 years the father will be the same age as his children put together
