Answer:
It's 15
Step-by-step explanation:
(5x+12) (6x+3)=180
5x+6x+12+3=180
11x+15=180
11x=180-15
11x=165
x=165/11
x=15

*PLEASE ANSWER ASAP* John is playing a game with two friends. Using the spinner pictured, one friend spun a three, and the other friend spun a five. John needs to spin a number higher than both friends in order to win the game, and he wants to calculate his probability of winning. How many desired outcomes should John use in his probability calculation?
Answer:
3
Step-by-step explanation:
Because Johns friends both got 3 and 5 so he needs a number higher to win i.e 6, 7, 8 so the answer is three.
Second Option is correct.
There will be 3 desired outcomes John should use in his probability calculation.
What is probability?Probability is the measure of the likelihood of occurrence of an event.
What is outcome?An outcome is a possible result of an experimental or trial.
Formula to calculate probability[tex]P(A) = \frac{number of favorable outcomes }{Total number of outcomes}[/tex]
where,
P(A) is the probability of an event.
According to the given question
we have
sample space = {1,2,3,4,5,6,7,8}
Total number of outcomes = 8
Jhon needs to spin a number higher than both friends in order to win the game
⇒ the numbers must be greater than 5
⇒ the numbers will be 6, 7, 8
therefore,
the total number of favorable outcomes =3.
Hence. there are 3 desired outcomes should John use in his probability calculation.

Angle F and angle G are complementary . The measure of angle F is three times the measure of angle G. What is the measure of each angle?
Answer:
[tex]g[/tex] = 22.5°
[tex]f[/tex] = 67.5°
Step-by-step explanation:
Let’s create a system of equations for [tex]f[/tex] and [tex]g[/tex].
Complementary angles are two angles that add up to 90°, so [tex]f+g=90[/tex]
Also, [tex]f[/tex] is thrice of g: [tex]f=3g[/tex]
We can now substitute [tex]3g[/tex] in [tex]f+g=90[/tex] for [tex]f[/tex].
[tex]3g + g = 90\\\\4g = 90\\\\g=22.5[/tex]
Now, we can find [tex]f[/tex] by substituting [tex]g[/tex] into either equation.
[tex]f + 22.5 = 90\\\\f = 90-22.5\\\\f = 67.5[/tex]

given -6b+22>-8 what is the largest integer b can represent
Answer:
5
Step-by-step explanation:
-6b> -8-22
-6b> -30
b> -30/-6
b>5
Answer:
So we have this inequality:
[tex]-6b + 22 > -8[/tex]
We substract 22 on both sides:
[tex]-6b > -30[/tex]
Now, we divide both sides by -6 and we change the sign, as, when we multiplicate or divide by a negative number we always have to do it:
[tex]b < \frac{-30}{-6}[/tex]
[tex]b < 5[/tex]
So we know b < 5, so the biggest integer b can represent is 4. Note that the solution is any number which is smaller than 5.
Use graphing technology to find the range of the function f(x)=x2 +6x+9
Answer:
See below.
Step-by-step explanation:
Refer to the graph.
The range of a graph is the span of y-values it covers.
From the graph, we can see that the span of y-values is all values greater than or equal to 0.
Therefore, our range is, in interval notation:
[tex][0,\infty)[/tex]
Note that we use brackets with the 0 because 0 is included in our range.
In set notation, this is:
[tex]\{y|y\in\mathbb{R},y\geq 0\}[/tex]

You would like to have $200,000 in a college fund in 15 years. How much do you need today if you expect to earn 12% while you are investing to pay for your child's college?
Answer:
$36,529.26
Step-by-step explanation:
To find the answer, you need to use the formula to calculate the present value:
PV=FV/(1+i)^n, where:
PV= present value
FV= future value= $200,000
i= interest rate= 12%
n= number of periods of time= 15
Now, you have to replace the values in the formula:
PV=200,000/(1+0.12)^15
PV=200,000/(1.12)^15
PV=36,539.26
According to this, the answer is that you need $36,529.26 today.

What is Logarithm?The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm
The properties of Logarithm are :
log A + log B = log AB
log A − log B = log A/B
log Aⁿ = n log A
Given data ,
Let the logarithmic equation be represented as A
Now , the value of A is
log₆ 18 = x
From the properties of logarithm , we get
log Aⁿ = n log A
On simplifying , we get
