Answer:
2 2/3 or 24/9
Step-by-step explanation:
3 2/9 - 5/9 = 24/9 = 2 6/9
3*9+2 = 29/9
29/9 - 5/9 = 2 6/9
2 6/9 turns into 2 2/3
2 2/3 is equal to 24/9
Answer:
2 2/3
Step-by-step explanation:
What you do is make 3 2/9 into an improper fractions --> 9 * 3 + 2 = 29/9
29/9 - 5/9 = 24/9
So, now you're going to make 24/9 into a mixed number which is 2 6/9 --> 2 2/3

Answer:
36[tex]\sqrt{3}[/tex] + 72
Step-by-step explanation:
The length of the rectangle = diameter of 2 circles = 4 × 3 = 12 mm
The width of the rectangle = 2 radii + distance d between radii ( lower to upper )
Using the right triangle formed by joining the 3 centres with legs 3 and d and hypotenuse 6
Using Pythagoras' identity, then
d² + 3² = 6²
d² + 9 = 36 ( subtract 9 from both sides )
d² = 27 ( take the square root of both sides )
d = [tex]\sqrt{27}[/tex] = 3[tex]\sqrt{3}[/tex]
Thus width of rectangle = 3 + 3[tex]\sqrt{3}[/tex] + 3 = 6 + 3[tex]\sqrt{3}[/tex]
Hence
area = length × width
= 12 × (6 + 3[tex]\sqrt{3}[/tex] ) = 36[tex]\sqrt{3}[/tex] + 72 mm ²
36 [tex]\sqrt{3}[/tex]+ 72
The length of the rectangle = diameter of 2 circles = 4 × 3 = 12 mm
The width of the rectangle = 2 radii + distance d between radii ( lower to upper )
Using the right triangle formed by joining the 3 centres with legs 3 and d and hypotenuse 6
Using Pythagoras' identity, then
d² + 3² = 6²
d² + 9 = 36 ( subtract 9 from both sides )
d² = 27 ( take the square root of both sides )
d = = 3
Thus width of rectangle = 3 + 3 + 3 = 6 + 3
Hence
area = length × width
= 12 × (6 + 3 ) = 36 + 72 mm ²
What are the roots of the equation x ^2+ 6x + 8 = 0?
Answers
Hi there! :)
Answer:
[tex]\huge\boxed{x = -4, -2}[/tex]
x² + 6x + 8 = 0
Factor the equation by finding two numbers that sum up to 6 and multiply into 8:
4 + 2 = 6
4 ×2 = 8
Rewrite in factored form:
(x + 4) (x + 2) = 0
Find the roots using the Zero-Product Property:
x + 4 = 0
x = - 4
x + 2 = 0
x = -2.
Therefore, the roots of this equation are at x = -4 and -2.

if m<FHI=142, what are m<FHG and m<GHI
Answers
angle FHG = 42 degrees
angle GHI = 100 degrees
=========================================================
Explanation:
FHI is the largest angle. It is split into two pieces FHG and GHI which have measures of (3x+6) and (9x-8) degrees respectively.
Put another way, those two smaller angles (FHG and GHI) combine to form the larger angle (FHI)
This is the angle addition postulate.
------------------
(angle FHG) + (angle GHI) = angle FHI
(3x+6) + (9x-8) = 142
3x+6+9x-8 = 142
(3x+9x) + (6-8) = 142
12x - 2 = 142
12x-2+2 = 142+2 ... adding 2 to both sides
12x = 144
12x/12 = 144/12 .... dividing both sides by 12
x = 12
------------------
Use that x value to find the angles we're after
angle FHG = 3x+6 = 3*12+6 = 36+6 = 42
angle GHI = 9x-8 = 9*12-8 = 108-8 = 100
Note how
(angle FHG) + (angle GHI) = 42 + 100 = 142
which is the measure of angle FHI. This confirms the answers.
joe is responsible for reserving hotel rooms for a company trip. His company changes plans and increases how many people are going on the trip, so they need at least 50 5050 total rooms. Joe had already reserved and paid for 16 1616 rooms, so he needs to reserve additional rooms. He can only reserve rooms in blocks, and each block contains 8 88 rooms and costs $ 900 $900dollar sign, 900. Let B BB represent the number of additional blocks that Joe reserves. 1) Which inequality describes this scenario? Choose 1 answer: Choose 1 answer: (Choice A) A 16 + 8 B ≤ 50 16+8B≤5016, plus, 8, B, is less than or equal to, 50 (Choice B) B 16 + 8 B ≥ 50 16+8B≥5016, plus, 8, B, is greater than or equal to, 50 (Choice C) C 16 + B ≤ 50 16+B≤5016, plus, B, is less than or equal to, 50 (Choice D) D 16 + B ≥ 50 16+B≥5016, plus, B, is greater than or equal to, 50 2) What is the least amount of additional money Joe can spend to get the rooms they need? dollars
Answers
The inequality expression is :
16 + 8B ≥ 50
Least amount that could be spent = $4500
The total number of rooms required should be atleast 50
Already booked = 16
Number of rooms per block = 8
If the number of blocks = B
Summing together :
Then we have :
16 + 8B ≥ 50
The leat additional amount to be spent:
(50 - 16) / 8
34/8 = 4.25
Least number of blocks, B = 5
Least amount = $900 * 5 = $4500

Inequalities are used to represent unequal expressions.
The inequality that represents the scenario is: [tex]8B + 16 \ge 50[/tex].The least additional amount is $4500Given that:
[tex]Room = 50[/tex] at least
[tex]Reserved = 16[/tex]
[tex]Rate = 8[/tex] per block
A. The inequality
Let the number of blocks be B.
"At least" means, greater than or equal to. So, we have:
[tex]Rate \times B + Reserved \ge 50[/tex]
Substitute known values
[tex]8 \times B + 16 \ge 50[/tex]
[tex]8B + 16 \ge 50[/tex]
So, the inequality that describes the scenario is:
[tex](b).\ 8B + 16 \ge 50[/tex]
B. The least amount
Solve for B in: [tex]8B + 16 \ge 50[/tex]
[tex]8B \ge 50 - 16[/tex]
[tex]8B \ge 34[/tex]
Divide both sides by 8
[tex]B \ge 4.25[/tex]
The number of blocks cannot be a decimal. So, we round 4.25 to the smallest integer greater than 4.25
This gives:
[tex]B \ge 5[/tex]
The least number of block is 5.
Given that:
[tex]Cost = \$900[/tex] per block
The least amount is calculated as follows:
[tex]Least = B \times Cost[/tex]
So, we have:
[tex]Least = 5 \times \$900[/tex]
[tex]Least = \$4500[/tex]
Hence, the least additional money is: $4500

In a class of 40 students, 30 read chemistry and 20 read physics. If all the students read at least one if the subjects, find the probability that a student selected at rand from the class reads only chemistry
Answers
hi
40 students
30 read chemistry
20 read physics
so logical deduction is that 10 read chemistry and physics.
So only 20 read only chemistry and only 10 read only physics.
So read only chemistry is 20/40 = 1/2
Answer as a fraction = 1/2
Answer in decimal form = 0.5
Answer in percent form = 50%
All three represent the same idea, but in a different form.
=======================================================
Work Shown:
30 read chem, 20 read physics
30+20 = 50 read either one, but this is over 40, so 50-40 = 10 students must read both
From that,
30-10 = 20 read chem only
20-10 = 10 read physics only
This makes the venn diagram you see below
Divide the number of people who read chemistry only (20) over the total number of people (40). This gives 20/40 = 2/4 = 1/2
Then you would use your calculator to find 1/2 = 0.5 = 50%

How do you tell when the slope is negative?
Answers
If the line goes downhill as you read from left to right, then the slope is negative.
The slope is positive when you go uphill, reading from left to right.
A slope of 0 means the line is completely horizontal or level
If the line is completely vertical, then the slope is undefined.
Suppose the roots of the polynomial $x^2 - mx + n$ are positive prime integers (not necessarily distinct). Given that $m < 20,$ how many possible values of $n$ are there?
Answers
Answer:
18 values for n are possible.
Step-by-step explanation:
Given the quadratic polynomial:
[tex]$x^2 - mx + n$[/tex]
such that:
Roots are positive prime integers and
[tex]$m < 20$[/tex]
To find:
How many possible values of [tex]n[/tex] are there ?
Solution:
First of all, let us have a look at the sum and product of a quadratic equation.
If the quadratic equation is:
[tex]Ax^{2} +Bx+C[/tex]
and the roots are: [tex]\alpha[/tex] and [tex]\beta[/tex]
Then sum of roots, [tex]\alpha+\beta = -\frac{B}{A}[/tex]
Product of roots, [tex]\alpha \beta = \frac{C}{A}[/tex]
Comparing the given equation with standard equation, we get:
A = 1, B = -m and C = n
Sum of roots, [tex]\alpha+\beta = -\frac{-m}{1} = m[/tex]
Product of roots, [tex]\alpha \beta = \frac{n}{1} = n[/tex]
We are given that [tex]m<20[/tex]
[tex]\alpha[/tex] and [tex]\beta[/tex] are positive prime integers such that their sum is less than 20.
Let us have a look at some of the positive prime integers:
2, 3, 5, 7, 11, 13, 17, 23, 29, .....
Now, we have to choose two such prime integers from above list such that their sum is less than 20 and the roots can be repetitive as well.
So, possible combinations and possible value of [tex]n (= \alpha \times \beta)[/tex] are:
[tex]1.\ 2, 2\Rightarrow n = 2\times 2 = 4\\2.\ 2, 3 \Rightarrow n = 6\\3.\ 2, 5 \Rightarrow n = 10\\4.\ 2, 7\Rightarrow n = 14\\5.\ 2, 11 \Rightarrow n = 22\\6.\ 2, 13 \Rightarrow n = 26\\7.\ 2, 17 \Rightarrow n = 34\\8.\ 3, 3\Rightarrow n = 3\times 3 = 9\\9.\ 3, 5 \Rightarrow n = 15\\10.\ 3, 7 \Rightarrow n = 21\\[/tex]
[tex]11.\ 3, 11\Rightarrow n = 33\\12.\ 3, 13 \Rightarrow n = 39\\13.\ 5, 5 \Rightarrow n = 25\\14.\ 5, 7 \Rightarrow n = 35\\15.\ 5, 11 \Rightarrow n = 55\\16.\ 5, 13 \Rightarrow n = 65\\17.\ 7, 7 \Rightarrow n = 49\\18.\ 7, 11 \Rightarrow n = 77[/tex]
So,as shown above 18 values for n are possible.
