Answer:
13
Step-by-step explanation:
f(x)=2(3x)+1
f(2)=2(3X2)+1
f(2)=2(6)+1
f(2)=12+1
f(2)=13
The value of function f(2) is 13.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
Given function; f(x) = 2 (3x) + 1
We need to find the value of f(2) .
f(x) = 2(3x)+1
f(2) = 2(3 * 2)+1
f(2) = 2(6)+1
f(2)=12+1
f(2)=13
Therefore, the value of function f(2) is 13.

9x + 5 = 4(x + 2) + 5x
solve for X
Answer:
no solution
Step-by-step explanation:
9x + 5 = 4(x+2) + 5x
9x + 5 = 4x + 8 + 5x
9x + 5 = 9x + 8
9x + 5 can never be equal to 9x + 8, so the answer is no solution
Answer:
x=3
Step-by-step explanation:
9x + 5 =4(x+2) + 5x
9x + 5= 4x + 8+ 5x ( do the parenthesis first- mulitiply 4 and x and get 4x and 4 times 2 = 8)
9x + 5 = 9x + 8 ( add the x's together 4x +5x = 9x )
9x = 9x + 3 ( subtract 5 both sides and you get 3 )
=3 ( subtract 9x from both sides

Trapezoid STUV is similar to trapezoid NOPQ. What is the length of OP?
Answer:
F. 4 2/3 centimeters
Step-by-step explanation:
since the trapezoids are similar to each other, that means there is a common ratio between them. so taking into consideration the first trapezoid STUV when we compare that to NOPQ, OP comes out to be 4 and 2/3 centimeters. start by comparing the ratio of ST to NO and then move on to TU and then OP.
. Since the pentagon is a regular pentagon, the measure of each interior angle will be the same.
To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.
(which is the same as the number of sides).
540° ÷ 5 = 108° There are 108° in each interior angle of a regular pentagon.
2. 540°
Sum of Interior Angles of a Polygon
A pentagon has five sides, thus the interior angles add up to 540°, and so on.

Spins a fair spinner numbered 1 - 5 and flips a fair coin. What is the probability of obtaining a factor of 15 and a tail?
Answer:
3/10
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that the fair spinner is numbered 1 - 5, the factors of 15 there are 1, 3 and 5 hence the probability of obtaining a factor of 15
= 3/5
The probability of obtaining a tail from the flip of a coin
= 1/2
Hence the probability of obtaining a factor of 15 and a tail
= 3/5 * 1/2
= 3/10

When Three friends divide four boxes of baseball trading cards ?evenly, they each get 48 cards. How many cards are in each box?
Answer:
36 cards in each box
Step-by-step explanation:
Let the number of cards in each box be x.
4 * x / 3 = 48 (4 packs of cards, three friends)
x / 3 = 21
x = 36.
Answer:
36 cards in each box
Step-by-step explanation:
Because each friend gets the same amount of cards, there needs to be 48*3 or 144 trading cards in total. There are 4 boxes so in each box there would be 144/4 or 36 cards in total.

Answer:
130z-3
Step-by-step explanation:
Break down the equation:
(9[tex]z^{2}[/tex]-4)=
9z * 9z= 81z
You can't subtract 4, so I left it at (81z- 4)
(7[tex]z^{2}[/tex]+ 1)=
7z * 7z= 49z
You can't add 1, so I left it at (49z+ 1)
Then Solve:
You can add 81z and 49z.
81z+49z= 130z
-4+1= -3

Question :
Two cargo ships spot a signal fire on a small island. The captains know they are 140 feet
away from each other and using angle measuring device they can determine the angle from
each of their ships to the signal fire. The angle at ship A is 82º and the angle at ship B is 78º.
How far is it from Ship B to the signal fire at point C?
Hint: Use Law of Sines:
sin A = simb = sin
82
140 it
A(48.9) b(400.4) C(405.3) D(673.4)
Answer:
C) 405.3 ft
Step-by-step explanation:
A triangle is a polygon with three angles and three sides. Types of triangle are scalene, isosceles, equilateral, right angled triangle.
Given a triangle with angles A, B, C and the corresponding sides directly opposite to the angles as a, b, c. The sine rule states that:
[tex]\frac{a}{sin(A)}= \frac{b}{sin(B)} =\frac{c}{sin(C)}[/tex]
In the triangle formed by point C, ship B and ship A, we have ∠A = 82°, ∠B = 78°, c = AB = 140 ft. Hence:
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
82 + 78 + ∠C = 180
∠C + 160 = 180
∠C = 20°
Using sine rule:
[tex]\frac{c}{sin(C)}=\frac{a}{sin(A)}\\\\\frac{140}{sin(20)}=\frac{a}{sin(82)}\\\\a= \frac{140*sin (82)}{sin(20)}\\\\a=405.3\ ft[/tex]
a = distance from Ship B to the signal fire at point C

Under his cell phone plan, Parker pays a flat cost of $36.50 per month and $5 per gigabyte. He wants to keep his bill under $45 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Parker can use while staying within his budget.
Answer: Parker can use 1.7 gigabytes to stay within his budget.
Step-by-step explanation:
If Parker pays a flat cost of $36.50 and has to pay $5 a month then we can represent it by the 36.50 + 5gg where gg is the number of gigabytes.
If he has to keep his bill under $45 , then 36.50 + 5gg has to be less than 45.
36.50 + 5gg < 45. Now solve for gg
-36.50 36.50
5gg < 8.5
gg< 1.7

Answer:
0.30 of a book / hour or 3/10 of a book per hour.
Step-by-step explanation:
Usually I tell people to put the numbers into decimals. Unfortunately for this question, it won't work. So we have any choice but to do it with fractions.
r = amount / time
amount = 1/4
time = 5/6
r = [tex]\frac{\frac{1}{4} }{\frac{5}{6} }[/tex]
Invert the denominator and multiply
r = [tex]\frac{1}{4} * \frac{6}{5}[/tex]
r = 6 * 1 / (5*4) = 6/20 = 3/10
The answer is 3/10 of a book per hour
5/6 of an hour is almost an hour.
1/4 of a book is 0.25 of a book.
3/10 of a book is 0.30 of a book. So it looks like it is just about right.

Answer
B. number five is right
Step-by-step explanation:
Answer:
$5
Step-by-step explanation:
First, subtract the $6 toy from the total of $71.
$71 - $6 = $65
The total of the shirts and pants is $65.
She bought 9 shirts and 4 pants, which would be 13 shirts and pants.
We then divide the total cost of the shirts and pants, $65 by the total shirts and pants, 13.
65 / 13 = 5
So, each shirt or pants costs $5.
