Hello, just need the answer for this question. Thank you for your help if you do so.
Answer:
In the first one you are missing (x - 3) so it will be 4(x - 3) and if you factor it out it will be 4x - 12
In the second one you are missing a (x -5)which means 9x(x -5) or when you factor it out it will be 9x^2 - 45x
Step-by-step explanation:
3x^2 -23x + 40 = (3x - 8) (x - 5)
3x^2 -17x + 24 = (3x -8) ( x - 3)
If the 12-sided solid is rolled 180 times, how many times would you expect either number a 3, 9 or 11 to be rolled?
The probability that the 12-sided solid gets 3 , 9 or 11 is P ( A ) = 1/4 and the expected number of times is n = 45
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability that the the 12-sided solid gets 3 , 9 or 11 be P ( A )
Now , the value of P ( A ) is
Let the number of outcomes when rolling a 12-sided solid = 12
The number of times the solid is rolled = 180 times
So , the total number of outcomes = 12 x 180 = 2160
And , the probability of getting a 3 = 1/12
The probability of getting a 9 = 1/12
The probability of getting a 11 = 1/12
So , the total probability of getting a 3 , 9 or 11 = 3/12 = 1/4
The total expected number of times = 45
Hence , the probability is 1/6

8.in South city elementary school, the number of grade 6 pupils is 2 less than half the number of grade 3 pupils. If there's are 60 grade 3 pupils, how many grade 6 pupils are there?
Answer:
2) The number is 4, 3) The number is 36, 4) The number is 16, 5) The number is 32, 6) The consecutive numbers are 14 and 15, 7) The solution of this system is: [tex]x = 17[/tex], [tex]y = 13[/tex], 8) The solution of this system is: [tex]x = 58[/tex], [tex]y = 60[/tex].
Step-by-step explanation:
Now we proceed to solve arithmetically on each statement:
2) Statement is incorrect, correct form is: Find [tex]x[/tex] if the product of [tex]x[/tex] by 12 is 48.
Mathematically speaking, we have the following formula:
[tex]12\cdot x = 48[/tex]
[tex]x = 4[/tex]
The number is 4.
3) Mathematically speaking, we have the following formula:
[tex]\frac{3\cdot x}{6} = 18[/tex]
[tex]\frac{x}{2} = 18[/tex]
[tex]x = 36[/tex]
The number is 36.
4) Mathematically speaking, we have the following formula:
[tex]\frac{5\cdot x}{4} = 20[/tex]
[tex]x = 16[/tex]
The number is 16.
5) Mathematically speaking, we have the following formula:
[tex]\frac{x}{2} = 16[/tex]
[tex]x = 32[/tex]
The number is 32.
6) Let be [tex]n[/tex] and [tex]n + 1[/tex], whose sum equals 29. Mathematically speaking, we have the following formula:
[tex]n + (n +1) = 29[/tex]
[tex]2\cdot n + 1 = 29[/tex]
[tex]n = 14[/tex]
The consecutive numbers are 14 and 15.
7) Let be [tex]x[/tex] and [tex]y[/tex] the quantities of pink and yellow roses. Mathematically speaking, we have the following system of linear equations:
[tex]x - y = 4[/tex] (1)
[tex]x + y = 30[/tex] (2)
The solution of this system is: [tex]x = 17[/tex], [tex]y = 13[/tex]
8) Let be [tex]x[/tex] and [tex]y[/tex] the numbers of grade 6 and grade 3. Mathematically speaking, we have the following system of linear equations:
[tex]x-y = -2[/tex] (3)
[tex]y = 60[/tex] (4)
The solution of this system is: [tex]x = 58[/tex], [tex]y = 60[/tex]

using the balanced equation 4FE+3O2 --> 2fe2O3 calculate how many grams of Fe2O3 are produced when 42.7 grams of Fe is reacted
The coefficients in the balanced reaction
4 Fe + 3 O₂ → 2 Fe₂O₃
represent the ratio of moles of each reactant to each product. That is, for every 4 moles of Fe and 3 moles of O₂, 2 moles of Fe₂O₃ are produced.
First convert the given amount of Fe into moles. Fe has a molar mass of 55.845 g/mol, so you have
42.7 g × (1/55.845 mol/g) = 0.765 mol
of Fe.
Find how many moles of Fe₂O₃ are produced given this much Fe and an abundant supply of O₂. Multiply the coefficients of the balanced reaction by 0.765/4 :
0.765 Fe + 0.573 O₂ → 0.382 Fe₂O₃
Now convert the amount of Fe₂O₃ to grams. O has a molar mass of 15.999 g/mol, so Fe₂O₃ has a total molar mass of about
2 (55.845 g/mol) + 3 (15.999 g/mol) = 159.687 g/mol
Then the reaction would produce about
0.382 mol × (158.687 g/mol) ≈ 61.0 g
of Fe₂O₃.
A large rectangular room needs to be carpeted and has dimensions 18.75 ft by 28 ft.
The carpet is sold by the square yard and has a cost of $26.50 per sq yd. Find the
cost to carpet the room (assume no extra needs to be purchased). Round answer to
two decimal places.
Answer:
$13912.50
Step-by-step explanation:
First you find how much carpet you need by finding the area of the room.
18.75*28= 525ft^2
Then multiply the amount of carpet needed by 26.50 to find the total cost.
525*26.50= 13912.50

Write the slope-intercept form of the line that travels through (4,-1) and is parallel to y = 1/4x
Answer:
y = 1/4x - 2
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = 1/4x. Its slope is 1/4. A line parallel to this one will also have a slope of 1/4.
Plug this value (1/4) into your standard point-slope equation of y = mx + b.
y = 1/4x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (4, -1). Plug in the x and y values into the x and y of the standard equation.
-1 = 1/4(4) + b
To find b, multiply the slope and the input of x (4)
-1 = 1 + b
Now, subtract 1 from both sides to isolate b.
-2 = b
Plug this into your standard equation.
y = 1/4x - 2
This equation is parallel to your given equation (y = 1/4x) and contains point (4, -1)
Hope this helps!
In triangle NOP p equals 600 inches angle P equals 96° and angle N equals 64° what is the area of triangle NOP to the nearest 10th of a square inch?
9514 1404 393
Answer:
55,637.8 square inches
Step-by-step explanation:
We can find side n using the Law of Sines:
n/sin(N) = p/sin(P)
n = p(sin(N)/sin(P)) = 600·sin(64°)/sin(96°)
n ≈ 542.246913 . . . . inches
The angle O is ...
O = 180° -N -P = 180° -64° -96° = 20°
Then the area is ...
A = 1/2·np·sin(O)
A = (1/2)(542.246913 in)(600 in)·sin(20°) ≈ 55,637.81008 in²
The area of ∆NOP is about 55,637.8 in².
