Answer 2

Answer:

R=51

Step-by-step explanation:

6x-9+7x=121

add like terms:6x+7x=13x

13x-9=121

to cancel out (-9) and to isolate x, add on both sides

13x=130

divide into both sides

x=10

to solve for angle R

substitute 10 for x

6(10)-9

R=51

Step 1: Divide both sides by o^2t.

fo2to2t=2.216717mrto2t

f=2.216717mro2

Answer:

f=2.216717mro2

Question 2:

Step 1: Add -11.82249iklmorst to both sides.

2.718282ilm+−11.82249iklmorst=11.82249iklmorst+−11.82249iklmorst

−11.82249iklmorst+2.718282ilm=0iklmorst

Step 2: Factor out variable i.

i(−11.82249klmorst+2.718282lm)=0iklmorst

Step 3: Divide both sides by -11.82249klmorst+2.718282lm.

i(−11.82249klmorst+2.718282lm)−11.82249klmorst+2.718282lm=0iklmorst−11.82249klmorst+2.718282l

Mary and Julie both have a goal of raising $1000 for
charity. Mary raises $12 every 4 days. Julie raises $19
every 6 days.
Will Mary or Julie reach her goal first? Explain.

This is the sample response… Mary would have a rise of 12 and a run of 4, making her slope, or rate of change, $3 a day. Julie would have a rise of 19 and a slope of 6, making her slope, or rate of change, $3.17 a day. Since Julie is raising money at a faster rate, she would get to the goal of $1000 first.

This is the info that you should include in your response… Mary has a rise of 12 and a run of 4. Mary has a slope of 3. Julie has a rise of 19 and a run of 6. Julie has a slope of 19/6 or 3 and 1/6. Julie will reach her goal first, as she has the greater slope.

Use this information at your advantage.
Hope this helps! :))

Answers

Answer:

Julie will reach her goal first because she raises $19 every 6 days so she is working 6 days out of one week. So she will get to her goal first.

What is the probability of rolling an even number and then an odd number when rolling two number cubes?
Size of sample spaces =
Number of desired outcomes =
P(first is even and second is odd) =

Answers

Answer:

First answer = 36

Second answer = 9

Third answer =1/4

Step-by-step explanation:

The probability of rolling an even number and then an odd number is 1/4.

What is Probability?

Probability is simply the chance of getting an event from a sample space. Total probability of all the outcomes in an experiment will be always 1.

Probability of an event can be found by dividing the number of desired outcomes with the total number of outcomes.

Here two number cubes are rolled. Each number cube has total 6 outcomes.

If the sample space consists of all the outcomes of first and second number cubes,

Size of sample space = 6² = 36

We have to find the probability of rolling an even number on the first cube and then an odd number on the second cube.

There are 3 chances of having an even number for the first cube which are 2, 4 and 6.

There are 3 chances of having an odd number for the second cube which are 1, 3 and 5.

Therefore number of desired outcomes = 3² = 9

Probability (first is even and second is odd) = Number of desired outcomes / Size of the sample space

Probability (first is even and second is odd) = 9/36 = 1/4

Hence the probability of getting an even number on the first number cube and then an odd number on the second cube is 1/4.

The variables x and y vary directly. Use the values to find the constant of proportionality, k. Then write an equation that relates x and y.

y=72; x=3

Answers

y = kx

Replace y and x to solve for k:

72 = 3k

Divide both sides by 3:

k = 24

Now replace k with 24:

y = 24x

The proportionality constant [tex]k=\frac{1}{24}[/tex], and the equation that relates [tex]x[/tex] and [tex]y[/tex] is [tex]x=\frac{1}{24}y\text{ or } y=24x[/tex]

Since [tex]x[/tex] and [tex]y[/tex] are related by direct proportion,

[tex]x \text{ }{\displaystyle \propto}\text{ }y \implies x=ky[/tex]

where [tex]k[/tex] is our proportionality constant. To find the value of [tex]k[/tex], substitute the values [tex]x=3\text{ and } y=72[/tex] into the formula, and solve for [tex]k[/tex].

[tex]x=ky\\\implies 3=72k\\\implies k=\frac{1}{24}[/tex]

Thus the equation that relates [tex]x[/tex] and [tex]y[/tex] is

[tex]x=\frac{1}{24}y\text{ or } y=24x[/tex]
