If f(x) = 3 - 2x and g(x)
=
1
X+ 5, what is the value of
(6)
(8)?
Answer:
-169
Step-by-step explanation:
An Arithmetic Combination states that two functions f and g at any x i.e in the domain of both f and g, with one exception.
The quotient is not defined at values of x, where g is equal to 0 or we can say that both the functions must be defined at a point for the combination to be defined.
Given: f(x) = 3-2x and g(x) =
Then, using arithmetic combination of function definition:
......[1]
Now, first find the value of f(9) and g(8) ;
f(8) =3-2(8) = 3-16 = -13 and
Substitute these in equation [1] ;
Therefore, the value of (f/g)(8) is; -169

The 8th grade class sold snacks at lunch to earn money for a field trip. They sold 30 items this week. For each snack type, what percentage of all snacks sold were of that type? Round to the nearest hundredth if necessary.
Answer:
Step-by-step explanation:
Total number of snacks sold by 8th grade class = 30
Percentage of a particular snack sold = [tex]\frac{\text{Number of particular snack sold}}{\text{Total number of all snacks sold}} \times 100[/tex]
Percentage of cookies sols = [tex]\frac{6}{30}\times 100[/tex] = 20%
Percentage of cheese sticks sold = [tex]\frac{8}{30}\times 100[/tex]
= 26.67%
Percentage of chips sold = [tex]\frac{12}{30}\times 100[/tex]
= 40%
Percentage of water sold = [tex]\frac{4}{30}\times 100[/tex]
= 13.33%

heidi subtract 9 from 17. first she adds to get 10.then she added again to find her answer is heidi correct Heidi is not correct to add blank then you add blank more to get 10 to 17 the answer is
Answer:
Heidi wants to compute:
17 - 9.
First, she adds to get 10, (we want to subtract 10, this is easier than subtracting 9) then she can do:
17 - 9 + 0
adding zero does not change the sum
1 - 1 = 0
then:
17 - 9 + 0 = 17 - 9 + 1 - 1
Now we can do:
17 - 9 - 1 + 1
17 - (9 + 1) + 1
17 - 10 + 1
(17 - 10) + 1
7 + 1 = 8
Then, first she needs to add -1, in order to subtract 10, and then she must add 1. As we added a number and its inverse, in total we added zero, so the sum did not change, but was easier to compute.
Then, you need
A couple wants to install a square mirror on their bathroom wall. The area of the square mirror is 720 square inches. To the nearest hundredth of an inch, what length of wood trim is needed to go around the entire mirror?PLZ ANSWER I NEED THIS IN LESS THAN 10 MINUTES
Answer:
26.83inches
Step-by-step explanation:
Area of the square mirror is expressed as A = L²
L is the side length of the square mirror
Given
Area = 720in²
Get the length
720 = L²
L = √720
L = 26.83
Hence the length of wood trim needed to go around the entire mirror is 26.83inches
To estimate the average education level, in years, of residents in a certain county, a marketing team draws a random sample of 100 residents. Their education level averages to about 12.5 years; the standard deviation is about 2.8 years. The team estimates the average education level of all the residents of that county to be 12.5 years with what margin of error, for approximately 90% confidence?
Answer:
The margin of error is [tex]E = 0.4606 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 100
The sample mean is [tex]\= x = 12.5 \ years[/tex]
The standard deviation is [tex]\sigma = 2.8 \ years[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E =1.645* \frac{ 2.8 }{\sqrt{100} }[/tex]
=> [tex]E = 0.4606 [/tex]
Sam is framing a closet under a stairway. The stairway is 20 ft 6 in. long, and its angle of elevation is 31º. Find the depth of the closet to the nearest inch.
Answer:
The depth is 127 inches.
Step-by-step explanation:
The stairway and its depth can be compared to a right angled triangle. Let the depth be represented by d.
But,
12 inches = 1 foot
20 ft 6 in = 20 + [tex](\frac{6}{12} )[/tex]
= 20.5 feet
So that applying the appropriate trigonometric function, we have;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Sin 31º = [tex]\frac{d}{20.5}[/tex]
d = 20.5 x Sin 31º
= 20.5 x 0.5150
d = 10.5575
d ≅ 11 feet
Therefore,
d = 10.5575 feet = (10.5575 x 12) inches
= 126.69 inches
The depth is 127 inches.

the sum of four consecutive odd numbers is 48?
Answer:
The numbers are 9 + 11 + 13 + 15.
Step-by-step explanation: The equation for this is simple.
Take x as the smallest number of the 4 numbers. The second number would be x +2, third number is x+4, and the fourth number is x+6. you add these together, and you get: 4x +12 = 48, you then solve this as a linear equation. 48-12 = 36. Then you divide by 4, which gives you 9 as the smallest number of the 4 numbers. Remember that the second number is 9+2=11, third is 9+4=13, and the fourth is 9+6=15. If you add these together you get 9+11+13+15=48.

Sally leaves her house and jogs along a straight road. After one hour she has gone 4 miles. Then, Sally slows to a brisk walk at a constant rate. After the first hour of walking in the same direction, Sally is 6.5 miles from her house. How many miles from her house will she be after two more hours of walking?
Answer:
I'm pretty sure its 11.5
Answer:
11.5 mi.
Step-by-step explanation:
First, you figure out how much miles Sally has gone by walking.
6.5-4=2.5 mi.
You use the distance formula: d(distance)=r(rate)xt(time)
2.5 mi.=Rx1 hr.
rate=2.5 mi/hr.
To figure out how many miles Sally will be from her house after two more hours of walking, you use the distance formula again.
d=2.5mi/hrx2 hr.
d=5.0 mi(2.5x2)
6.5mi+5.0mi=11.5 mi total
(45x-7)4x=57 solve this and ill make out with you
Answer:
After solving [tex](45x-7)4x=57[/tex] we get [tex]\mathbf{x=0.645 \ or \ x = -0.490}[/tex]
Step-by-step explanation:
We need to solve the equation: [tex](45x-7)4x=57[/tex]
Solving:
[tex](45x-7)4x=57[/tex]
Multiply 4x with terms inside the bracket
[tex]180x^2-28x=57[/tex]
[tex]180x^2-28x-57=0[/tex]
We need to solve above equation to find value of x
Using quadratic formula for finding value of x: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a=180, b=-28 and c=-57
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-28)\pm\sqrt{(-28)^2-4(180)(-57)}}{2(180)}\\x=\frac{28\pm\sqrt{784+41040}}{360}\\x=\frac{28\pm\sqrt{41824}}{360}\\x=\frac{28\pm204.51}{360}\\x=\frac{28+204.51}{360} \ or \ x=\frac{28-204.51}{360}\\x=0.645 \ or \ x = -0.490[/tex]
Values of x are [tex]\mathbf{x=0.645 \ or \ x = -0.490}[/tex]
So, After solving [tex](45x-7)4x=57[/tex] we get [tex]\mathbf{x=0.645 \ or \ x = -0.490}[/tex]
Use the distributive property to remove the parentheses.
10(u-2)
Answer:
After using distributive property to remove the parentheses [tex]10(u-2)[/tex] we get [tex]10u-20[/tex]
Step-by-step explanation:
We need to use distributive property to remove the parentheses 10(u-2)
According to distributive property of multiplication over subtraction: [tex]a(b-c)=ab-ac[/tex]
Using the above distributive property to solve the question. Multiply 10 with terms inside the bracket and solving:
[tex]10(u-2)\\=10u-10*2\\=10u-20[/tex]
So, After using distributive property to remove the parentheses [tex]10(u-2)[/tex] we get [tex]10u-20[/tex]

The probability that a randomly selected 2 2-year-old male garter snake garter snake will live to be 3 3 years old is 0.98861 0.98861. (a) What is the probability that two randomly selected 2 2-year-old male garter snake garter snakes will live to be 3 3 years old? (b) What is the probability that seven seven randomly selected 2 2-year-old male garter snake garter snakes will live to be 3 3 years old? (c) What is the probability that at least one of seven seven randomly selected 2 2-year-old male garter snake garter snakes will not live to be 3 3 years old? Would it be unusual if at least one of seven seven randomly selected 2 2-year-old male garter snake garter snakes did not live to be 3 3 years old?
Answer:
a. [tex]Probability = 0.97735[/tex]
b. [tex]Probability = 0.92294[/tex]
c. [tex]P(At\ Least\ One) = 1[/tex]
No, it is not unusual if at least 1 lives up to 3.
Step-by-step explanation:
Given
Represent the probability that a 2 year old snake will live to 3 with P(Live);
[tex]P(Live) = 0.98861[/tex]
Solving (a): Probability that two selected will live to 3 years.
Both snakes have a chance of 0.98861 to live up to 3 years.
So, the required probability is:
[tex]Probability = P(Live)\ and\ P(Live)[/tex]
[tex]Probability = 0.98861 * 0.98861[/tex]
[tex]Probability = 0.9773497321[/tex]
[tex]Probability = 0.97735[/tex] --- Approximated
Solving (b): Probability that seven selected will live to 3 years.
All 7 snakes have a chance of 0.98861 to live up to 3 years.
So, the required probability is:
[tex]Probability = P(Live)^n[/tex]
Where [tex]n = 7[/tex]
[tex]Probability = 0.98861^7[/tex]
[tex]Probability = 0.92294324145[/tex]
[tex]Probability = 0.92294[/tex] --- Approximated
Solving (c): Probability that at least one of seven selected will not live to 3 years.
In probabilities, the following relationship exist:
[tex]P(At\ Least\ One) = 1 - P(None).[/tex]
So, first we need to calculate the probability that none of the 7 lived up to 3.
If the probability that one lived up to 3 years is 0.98861, then the probability than one do not live up to 3 years is 1 - 0.98861
This gives:
[tex]P(Not\ Live) = 0.01139[/tex]
The probability that none of the 7 lives up to 3 is:
[tex]P(None) = P(Not\ Live)^7[/tex]
[tex]P(None) = 0.01139^7[/tex]
Substitute this value for P(None) in
[tex]P(At\ Least\ One) = 1 - P(None).[/tex]
[tex]P(At\ Least\ One) = 1 - 0.01139^7[/tex]
[tex]P(At\ Least\ One) = 0.99999999999997513055642436060443621[/tex]
[tex]P(At\ Least\ One) = 1[/tex] ---- Approximated
No, it is not unusual if at least 1 lives up to 3.
This is so because the above results, which is 1 shows that it is very likely for at least one of the seven to live up to 3 years

Answer:
m<L.F.M = 50
Step-by-step explanation:
So we know that the m<F.M.L = 90 and m<F.M.P = 90 so...
3x- 1 + 2x + 6 = 90 (collect like terms)
5x + 5 = 90 (subtract 5 on both sides)
5x = 85 (divide by 5 on both sides)
x = 17
Plug in to (3x-1)
3(17) - 1 = m<L.F.M
50 = m<L.F.M
