If f (n)= - 3n + 2, what is the value of f(12) ?
Answer:
Step-by-step explanation:
f(n)= -3n + 2
to find :f(12)
substitute 12 in place of n
f(12)= -3*12 + 2
f(12)=-36 + 2
f(12)= -34
The value of the f(12) is equal to -46 where the expression is
f(n) = -3n + 2.
What is an expression?Any mathematical statement which consist of numbers , variables and arithmetic operations is known as expression. An expression gives some numerical value when we put the value of variables in it.
Here, f(n)= -3n + 2 is the given expression.
So, we can find the value of f(12) by putting n=12 in f(n).
Put n=12 in f(n), we get
f(12)= (-3)×12 + 2
= -48 + 2
= -46
Hence, the value of f(12) is -46.

A warehouse has a height of 8\frac{1}{2}8 2 1 meters, length of 120120 meters, and width of 20\frac{3}{10}20 10 3 meters. What is the volume of the warehouse?
Answer: [tex]20,706\ m^3[/tex]
Step-by-step explanation:
Given
The warehouse has the following dimension
Height is [tex]h=8\frac{1}{2}\ m[/tex]
[tex]h=\dfrac{17}{2}\ m[/tex]
Length is [tex]l=120\ m[/tex]
Width is [tex]w=20\frac{3}{10}\ m[/tex]
[tex]w=\dfrac{203}{10}\ m[/tex]
Volume of the warehouse is the product of height, length and width
[tex]\Rightarrow V=h\times l\times w\\\\\Rightarrow V=\dfrac{17}{2}\times 120\times \dfrac{203}{10}\\\\\Rightarrow V=20,706\ m^3[/tex]
Therefore, the length of the warehouse is [tex]20,706\ m^3[/tex].

In a carnival game, players get 5 chances to throw a basketball through a hoop. If 7 out of 20 players made all 5 baskets, how many players out of 400 would you expect to make all 5 baskets?
=====================================================
Work Shown:
7/20 = 0.35 = 35% of the 20 players made all five baskets.
If this trend holds up, then we should expect 35% of the 400 people to make all five baskets.
35% of 400 = 0.35*400 = 140
We expect about 140 people will make all five baskets.
Note how 140/400 = 0.35 = 35%
-------------
Through another alternative method, we can solve like this
7/20 = x/400
7*400 = 20*x ... cross multiply
2800 = 20x
20x = 2800
x = 2800/20 ... dividing both sides by 20
x = 140 which is the same result as before
What are the solutions of the equation (5x − 2)(x + 6) = 0?
A. 0.4, −6
B. no real solution
C. −0.4, 6
D. 2.5, −6
Answer:
A. 0.4 , -6
Step-by-step explanation:
equate each of them to 0
5x - 2 =0 , x + 6 = 0
5x = 2 , x = 0 - 6
x = 2/5 , x = -6
x = 0.4 , x = -6

At Applebees, the average diner tips the waiter 20% of their total bill. Finn's bill was $66.50. How much money should Finn tip the waiter?
Answer:
56
Step-by-step explanation:
Answer:
13.3 US$
Step-by-step explanation:
How to find it
Written using the formula: x = 66.50 ÷ 20%
Convert the percent to a decimal.
20% ÷ 100 = 0.2.
X = 66.50 ÷ 0.2.
So 20% of 66.60 is 13.3.

Factorize x²+7x+10. Show working please
Answer:
(x + 2)(x + 5)
Step-by-step explanation:
Given
x² + 7x + 10
Consider the factors of the constant term (+ 10) which sum to give the coefficient of the x- term (+ 7)
The factors are + 2 and + 5 , since
5 × 2 = + 10 and 2 + 5 = + 7 , then
x² + 7x + 10 = (x + 2)(x + 5) ← in factored form

Answer:
Length of old board = 68.2cm
Step-by-step explanation:
Let old board length be x
Given new board is 120 % longer than old board = x + 120% of x
Length of new board = 150cm
Therefore,
x + 120% of x = 150
[tex]x + \frac{120}{100} x = 150\\\\x + 1.20x = 150\\\\2.2x = 150 \\\\x = 68.18 = 68.2cm[/tex]

the sum of the two fractions is 9/26. if one of the fraction is 1/13, find the other
Answer:
7/26
Step-by-step explanation:
let the other fraction be x
according to the question,
1/13 +x =9/26
x = 9/26 - 1/13
take lcm of the denominator . lcm=26
x = 9*1 - 1*2/26
x = 9-2/26
x=7/26

Answer:
7.5
Step-by-step explanation:
Median = middle number in terms of value
To make it easier to identify the middle number lets list the number from least to greatest
1, 4, 4, 7, 8, 8, 10, 15
Now we can simply find the middle number
We notice that there are two middle numbers as there is an even amount of numbers
Those two numbers being 7 and 8
When finding the median, if there are two middle numbers, you simply add the two numbers together and divide the sum by two to get the median.
So median = 8 + 7 = 15 / 2 = 7.5
Answer:
7.5
Step-by-step explanation:
The median of a set of numbers is the middle number, so we have to order them first from least to greatest. The order would be 1, 4, 4, 7, 8, 8, 10, 15. You can see that there are an even number of numbers, so if we take the two numbers in the middle of the order (7 and 8) and add them to get 15 and divide 15 by two, we get an answer of 7.5.
