What is the length, in feet, of the amount of board remaining after Tim makes the cuts?
Answer: 12.4
Step-by-step explanation:
Use the given functions to set up and simplify
12.4
feet.
4=2.75 feet=20.31990427 ft12.4 feet=91.62429562 ft
Answer:
1.4 feet
Step-by-step explanation:
2.75 times 4 = 11
11 is the total length of the boards cut
12.4 - 11 = 1.4

Answer:
x≥12, Michael must grow for 12 more months (a year) before he can ride a roller coaster.
Step-by-step explanation:
The inequality to represent how tall you must be to go on a roller coaster is
x≥48 because you must be a minimum of 48 inches tall, 'x' represents how tall you must be
If Michael is already 42 inches tall, that is his base point but you need to know how many more months he will need to grow for.
1/2x represents the amount of months Michael needs to grow, x is the unknown variable we need to solve for which represents the months he needs to grow, 1/2 is how many inches he grows in 1 month
42+1/2x≥ 48
subtract 42 from each side) 1/2x≥6
multiply both sides by 2) x≥12

Tony’s Pizzeria customers were asked what kind of pizza topping they prefer. Tony learned that 20 customers selected pepperoni, 12 selected mushrooms, and 8 selected pepperoni and mushrooms. What is the probability that a randomly selected customer selected pepperoni but not mushrooms?
A.1/2
B.2/5
C.3/5
D.3/8
Answer:
A. 1/2
Step-by-step explanation:
First, find how many customers there were:
20 + 12 + 8
= 40
20 customers selected pepperoni only, so to find the probability that they chose pepperoni but not mushrooms, divide the amount by the total:
20/40
= 1/2
So, the probability is 1/2

What value of n makes
(5^n)(5^2)=5^16 true?
Answer:
14
Step-by-step explanation:
By following the exponent rule, when multiplying two numbers of the same term with exponents, you simply add them together.
Therefore, to make (5^n)(5^2)=5^16 true, n must equal 14 since:
14 + 2 = 16
Answer:
n = 14
Step-by-step explanation:
Recall the rule:
[tex] a^m \times a^n = a^{m + n} [/tex]
[tex] (5^n)(5^2) = 5^{16} [/tex]
[tex] (5^n)(5^2) = 5^{n + 2} = 5^{16} [/tex]
[tex] n + 2 = 16 [/tex]
[tex] n = 14 [/tex]
Is the trend line linear? If so, write a linear equation that represents the trend line. Show your work.
A graph showing the fat and calories content has increased in the number of calories with the increasing number of fat.
A linear trend is the best fit straight line that is showing a positive relationship as it's going upwards. As the plotted residues represent a line that is almost straight and these data points resemble a line. This trend shows an increase in the data correlation. For example, the increased in distance will lead to an increase in time and this can be positively correlated within the graph. The equation of y = MX + b and y = 10x + 0 for a and b.Thus the graph shows a linear trend and in increasing order.

Answer:
The equation is "Y = 56.36*X + 56.47"
Step-by-step explanation:
The form of the equation is y=mx+b, m = slope and b = intercept.
You have to find the slope of the trend line or you can use the plot points, but identifying the slope in the trend line is much easier.
It seems there are two points that are outliers and need no paying attention to, this is because outliers can make predictions unreliable and also make the trend line unreliable overall as well.

9x+4=6x + 6
I need to find x please help
Answer:
x = 2/3
Step-by-step explanation:
9x + 4 = 6x + 6
Subtract 4 from both sides
9x + 4 - 4 = 6x + 6 - 4
9x = 6x + 2
Subtract 6x from both sides
9x - 6x = 2
3x = 2
Divide both sides by 2
3x/3 = 2/3
x = 2/3
Answer:x=2/3

Nicole is making tuna salad for her office colleagues. It takes 2/5 of a pound of canned tuna to make 5 portions of salad. She uses 1 1/5 pounds of canned tuna for every 2 onions used. If Nicole uses a total of 4 onions, then how many portions of salad does she make?
Answer:
30 portions of salad
Step-by-step explanation:
Given that :
2/5 pounds of canned tuna = 5 portions of salad
For every 2 onions used, 1 1/5 pounds of canned tuna is used ;
Number of onions used = 4
If 4 onions were used, number of canned tuna used is ;
4 /2 * 1 1/5
= 2 * 1 1/5
= 2 * 6/5
= 12 / 5 = 2 2/5 pounds of canned tuna
Number of Portions of salad made :
2/5 pounds = 5 portions of salad
12/5 pounds = x
2/5 * x = 12/5 * 5
2/5x = 60 /5
2/5 x = 12
x = 12 ÷ 2/5
x = 12 * 5 /2
x = 60/2
x = 30 portions of salad
In an AP. 19th term is 52 and 38th term is 128. Find the sum of the first 56 terms.
19th term of an AP = 52
38th term = 128
Find:the sum of the first 56 terms
Solution:We know that,
nth term of an AP – a(n) = a + (n - 1)d
Hence,
→ a + (19 - 1)d = 52
→ a + 18d = 52 -- equation (1)
Similarly,
→ a + (38 - 1)d = 128
→ a + 37d = 128 -- equation (2)
Subtract equation (1) from (2).
→ a + 37d - (a + 18d) = 128 - 52
→ a + 37d - a - 18d = 76
→ 19d = 76
→ d = 76/19
→ d = 4
Substitute the value of d in equation (1).
→ a + 18 * 4 = 52
→ a = 52 - 72
→ a = - 20
We know,
Sum of first n terms of an AP – S(n) = n/2 * [ 2a + (n - 1)d ]
Hence,
→ S(56) = 56/2 * [ 2 (- 20) + (56 - 1) * (4) ]
→ S(56) = 28 * [ - 40 + 55 * 4 ]
→ S(56) = 28 * [ - 40 + 220 ]
→ S(56) = 28 * (180)
→ S(56) = 5040
Hence, the sum of first 56 terms of the given AP is 5040.
I hope it will help you.
Regards.

What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression. A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.
Given that in an AP. 19th term is 52 and 38th term is 128.
nth term of an AP – a(n) = a + (n - 1)d
a + (19 - 1)d = 52
a + 18d = 52 -- equation (1)
Similarly,
a + (38 - 1)d = 128
a + 37d = 128 -- equation (2)
Subtract equation (1) from (2).
a + 37d - (a + 18d) = 128 - 52
a + 37d - a - 18d = 76
19d = 76
d = 76/19
d = 4
Substitute the value of d in equation (1).
a + 18 * 4 = 52
a = 52 - 72
a = - 20
Sum of first n terms of an AP – S(n) = n/2 * [ 2a + (n - 1)d ]
S(56) = 56/2 * [ 2 (- 20) + (56 - 1) * (4) ]
S(56) = 28 * [ - 40 + 55 * 4 ]
S(56) = 28 * [ - 40 + 220 ]
S(56) = 28 * (180)
\S(56) = 5040
Hence, the sum of the first 56 terms of the given AP is 5040.

Find the area. Simplify your answer.
Answer:
area = x² - 7x
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 2x and h = x - 7 , thus
A = [tex]\frac{1}{2}[/tex] × 2x(x - 7) = x(x - 7) = x² - 7x
Answer:
a=x^2-7x
Step-by-step explanation:

Answer:
slope (m) = [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Find the slope by using the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
([tex]x_1 , y_1[/tex]) = (1 , 2)
([tex]x_2 , y_2[/tex]) = (7 , 7)
Plug in the corresponding numbers to the corresponding variables:
slope (m) = [tex]\frac{7 - 2}{7 - 1} = \frac{5}{6}[/tex]
slope (m) = [tex]\frac{5}{6}[/tex]
~
[tex] \LARGE{ \underline{ \purple{ \bf{Required \: answer:}}}}[/tex]
We can find the slope (m) by using the formula:
[tex] \rm{m = \dfrac{y2 - y1}{x2 - x1} }[/tex]The points given to us:
(x1 , y1) = (1 , 2)(x2 , y2) = (7 , 7)Plugging the given values of x1, y1, x2 and y2 to find the slope:
[tex] \rm{m = \dfrac{7 - 2}{7 - 1} }[/tex]
This is equals to,
[tex] \rm{m = \dfrac{5}{6} }[/tex]
And this is our required result....
