What is k+3 3/4 = 5 2/3 - 1 1/3

1 answer:

4 0

K+3 3/4=5 2/3-1 1/3
k+3 3/4=4 1/3
lets find the lcm first then multiply both sides by it but first change it to improper fraction
LCM is 12

[k+15/4]=[13/3]12
12k+45=52
12k=7
k=7/12

Find the value of x so that the function has the given value. f(x) = 6x + 9; f(x) = 21

Olin [163]

Answer:

$x = 2$

Step-by-step explanation:

We need to find the value of x so that the value of given function becomes 21 .

We have ,

$f(x)=21\\\\ f(x)= 6x + 9$

Now , for finding x ,

$6x +9 = 21 \\\\ 6x = 21 -9 \\\\ 6x = 12 \\\\ x = 2$

Suppose the weather forecast calls for a 60% chance of rain each day for the next 3 days. What is the probability that it will N

erastovalidia [21]

Answer:

Probability that it'll not rain during the next three days = 0.064

Step-by-step explanation:

Given

Let:

P(R) represent the probability that it'll rain each day

P(R') represent the probability that it'll not

$P(R) = 60\%$

Required

Probability that it'll not rain during the next three days

From concept of probability;

$P(R) + P(R') = 1$

Substitute 60% for P(R)

$60\% + P(R') = 1$

Subtract 60% from both sides

$60\% - 60\% + P(R') = 1 - 60\%$

$P(R') = 1 - 60\%$

Convert % to decimal

$P(R') = 1 - 0.6$

$P(R') = 0.4$

The probability that it'll not rain during the next 3 days is:

$P(R') * P(R') * P(R')$

$P(R') * P(R') * P(R') =0.4 * 0.4 * 0.4$

$P(R') * P(R') * P(R') = 0.064$

pls help for 15 points asap Phil traveled with his family by car. They started their trip from Lexington to Louisville, driving

victus00 [196]

Given that Phil traveled with his family by car. They started their trip from Lexington to Louisville, driving directly west for 60 miles.

So AB=60

They then turned North, driving to Indianapolis which is 100 miles from Lexington.

So AC=100

Then, they turned to the West again, and drove to Decatur which which is 170 straight miles from Louisville.

so BD=170

Now we have to find about how many miles did they cover in total driving from Lexington to Decatur.

That means we have to find length of (AB+BC+CD)

We can use Pythogorean theorem to find the values of BC and CD.

$BC=\sqrt{AC^2-AB^2}=\sqrt{100^2-60^2}=\sqrt{10000-3600}=\sqrt{6400}=80$

$CD=\sqrt{BD^2-BC^2}=\sqrt{170^2-80^2}=\sqrt{28900-6400}=\sqrt{22500}=150$

then (AB+BC+CD)=60+80+150= 290

Hence final answer is miles.
