Answer 1
Answer:
1.625
Step-by-step explanation:
So you have to convert the 5/8ths into something that can go into 10.
So 100/8 is equivalent to 12.5. But you'll have to make that into decimal form, so move that 2 places to the right, to get 0.125. 0.125 times 5 is 0.625. And 1 is just 1 as a whole number. 1 plus 0.625 is 1.625.

Answers
Answer:
C. The number 5/11 is a rational number because it is a repeating decimal.
Step-by-step explanation:
The importance of this question is to distinguish a rational number from an irrational number.
A rational number can be written as a ratio or a set of repeating decimals.
An irrational number cannot be written as a ratio and cannot be represented by repeating decimals.
So out of the four options you have, the first two, A and B, are false, C is true, and D is false since rationality doesn't have anything to do with signs.

in a triangle PQR,if angle P is equal to 60 and angle Q is equal to 40 degree what the value of exterior angle formed by producing QR
Answers
Answer: 140 degrees
==================================================
Explanation:
See the diagram below.
We start with triangle PQR with the given angles mentioned. Then you extend out segment QR to form line QR. It goes off infinitely in both directions.
The exterior angle x adds to the interior angle Q = 40 to get 180
x+40 = 180
x+40-40 = 180-40 ... subtract 40 from both sides
x = 140
The exterior angle is 140 degrees
find the midpoint of the line segment joining points A(6,-5) and B(,6,1)
Answers
Answer: (6, -2)
Explanation:
The two given points have x coordinates of x = 6 each. They add to 6+6 = 12. Divide this in half to get 12/2 = 6. Since the x coordinates were both the same, the midpoint x coordinate is the same as well.
The y coordinates are a bit more interesting. Add them up to get -5+1 = -4. Then cut this in half to get -4/2 = -2. The y coordinate of the midpoint is -2.
Overall, the midpoint is (6, -2)

Answers
Answer:
The correct option is;
B. GT PT ET GV PV EV
Step-by-step explanation:
The given information we have;
The number mathematics topics Travis has to chose from tonight = 3 topics
The number of ways he can chose to study each topic = 2 ways
Therefore the number of different combo Travis can chose from is given as follows;
The number of combos = The number of topics × The number of ways
∴ The number of combos = 3 × 2 = 6 combos
Therefore, the possible combos are;
B. GT PT ET GV PV and EV which is the same as GT, GV, PT, PV, ET, and EV.
Nswer two questions about Systems A AA and B BB: System A AA start text, end text System B BB { − 3 x + 12 y = 15 7 x − 10 y = − 2 ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ −3x+12y=15 7x−10y=−2 { − x + 4 y = 5 7 x − 10 y = − 2 ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ −x+4y=5 7x−10y=−2 1) How can we get System B BB from System A AA? Choose 1 answer: Choose 1 answer: (Choice A) A Replace one equation with the sum/difference of both equations (Choice B) B Replace only the left-hand side of one equation with the sum/difference of the left-hand sides of both equations (Choice C) C Replace one equation with a multiple of itself (Choice D) D Replace one equation with a multiple of the other equation
Answers
Answer:
(Choice C) C Replace one equation with a multiple of itself
Step-by-step explanation:
Since system A has the equations
-3x + 12y = 15 and 7x - 10y = -2 and,
system B has the equations
-x + 4y = 5 and 7x - 10 y = -2.
To get system B from system A, we notice that equation -x + 4y = 5 is a multiple of -3x + 12y = 15 ⇒ 3(-x + 4y = 5) = (-3x + 12y = 15).
So, (-x + 4y = 5) = (1/3) × (-3x + 12y = 15)
So, we replace the first equation in system B by 1/3 the first equation in system A to obtain the first equation in system B.
So, choice C is the answer.
We replace one equation with a multiple of itself.

Diego and Max are buying soft drinks for a neighborhood picnic. Each person is expected to drink one can of soda. Diego says that if you multiply the unit price for a can of soda by the number of people attending the picnic, you will be able to determine the total cost of the soda. Max says that if you divide the cost of a 12-pack of soda by the number of sodas, you will determine the total cost of the sodas.
Which choices best illustrates who is correct and why?
Max is incorrect because he calculated the cost of one can of soda
Diego is incorrect because he calculated the price of one can of soda
Max is correct because the total cost divided by the number of sodas gives you the total cost of the sodas
Diego is correct because the price of one can of soda multiplied by the number of sodas needed will give you the total cost of the soda.
Answers
Answer:
D). Diego is correct because the price of one can of soda multiplied by the number of sodas needed will give you the total cost of the soda.
Step-by-step explanation:
Since every person is expected to drink one can of soda:
Let the price of each can of soda = p
and the total number of people present at the picnic = n
∵ Total price = p(the price of each soda can) * n(number of people)
Thus, Diego correctly asserts that if he multiplies the 'unit price for a can of soda by the number of people attending the picnic', he would be able to deduce the total cost of soda. Hence, Max is incorrect and option D is the correct answer.
A liter of water contains about (first image) molecules. A certain river discharges about (second image) L of water every second. About how many molecules does the river discharge every minute? Write your answer in scientific notation.
Answers
Answer: 4.623 * 10^34 molecules
================================================
Work Shown:
1 second = 2.3 * 10^7 liters of water
60*1 second = 60*2.3* 10^7 liters of water
60 seconds = 138 * 10^7 liters of water
1 minute = (1.38 * 10^2) * 10^7 liters of water
1 minute = 1.38 * (10^2*10^7) liters of water
1 minute = 1.38 * 10^(2+7) liters of water
1 minute = 1.38 * 10^9 liters of water
The river discharges 1.38 * 10^9 liters of water per minute.
--------------------------------
1 liter = 3.35 * 10^25 molecules
1.38 * 10^9*1 liter = 1.38 * 10^9*3.35 * 10^25 molecules
1.38 * 10^9 liters = (1.38*3.35) * (10^9*10^25) molecules
1.38 * 10^9 liters = 4.623 * 10^(9+25) molecules
1.38 * 10^9 liters = 4.623 * 10^34 molecules
1 minute = 4.623 * 10^34 molecules
-------------------------------
Every minute, about 4.623 * 10^34 molecules of water are discharged from the river.

For annual salaries, on the first $11,000, no income tax is paid, 2. On the first $11,000 to $25,000, 8% of the income is deducted, 3. On the first $25,000 to $50,000, 12% of the income is deducted, 4. On the first $50,000 to $100,000, 15% of the income is deducted, 5. And on the rest of the income, 20% of that income is deducted. Henry makes an annual gross salary of $70,000, what is his net salary?
Answers
Answer:
$57,700
Step-by-step explanation:
The deductions are ...
for pension and employment insurance, (5+2.4)% of $70,000
= 0.074 × $70,000 = $5,180
for income tax, ...
8% of the 14,000 between $11,000 and $25,000 = $1,120
12% of the 25,000 between $25,000 and $50,000 = $3,000
15% of the 20,000 between $50,000 and $70,000 = $3,000
Then the total of deductions is ...
$5,180 +1,120 +3,000 +3,000 = $12,300
Net salary after these deductions is ...
$70,000 -12,300 = $57,700

17. Factorise using factor theorem:
x^3-3x^2-4x+12
Answers
Answer:
(x - 3)(x - 2)(x + 2)
Step-by-step explanation:
Given
x³ - 3x² - 4x + 12 ( factor the first/second and third/fourth terms )
= x²(x - 3) - 4(x - 3) ← factor out (x - 3) from each term
= (x - 3)(x² - 4) ← x² - 4 is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
x² - 4
= x² - 2²
= (x - 2)(x + 2)
Thus
x³ - 3x² - 4x + 12 = (x - 3)(x - 2)(x + 2) ← in factored form
Answer:
(x - 2)(x - 3)(x + 2).
Step-by-step explanation:
The Factor Theorem states that if x - a is a factor of f(x) the f(a) = 0.
f(x) = x^3 - 3x^2 - 4x + 12
We try the factors of 12:
f(2) = 2^3 - 3*4 - 8 +12
= 8 - 12 - 8 + 12 = 0
- so (x - 2) is a factor of f(x)
Dividing:
x^2 - x - 6 <-----------Quotient
-----------------------------
x - 2 )x^3 - 3x^2 - 4x + 12
x^3 - 2x^2
-x^2 - 4x
-x^2 + 2x
-6x + 12
-6x + 12
So we factor x^2 - x - 6:
= (x - 3)(x + 2)

Step-by-step explanation:
2x+4(x-1)=2+4x
Expand brackets.
2x+4x-4=2+4x
Combine like terms.
6x-4=2+4x
Subtract 4x from both sides.
Add 4 to both sides.

25-x=15-(3x+10)
Distribute negative sign.
25-x=15-3x-10
25-x=-3x+5
Add x and -5 to both sides.
20=-2x
Divide both sides by -2.
-10=x (One solution)
4x=2x+2x+5(x-x)
Solve for brackets.
4x=2x+2x+5(0)
4x=2x+2x
Combine like terms.
4x=4x
Divide both sides by 4.

John and 4 friends are going out for pizza. They split one pizza and
5 drinks. The pizza cost $12.50 and they spent a total of $19.25.
Answers
Answer:
Step-by-step explanation:
If you are asking how much money were the drinks?
Then, the answer is $6.75. This is because 19.25 - 12.50 = 6.75
If you are asking how much money per drink, then the answer is $1.35
What is the question? If they’re asking how much each drink cost then the answer would be: $1.35 because you have to subtract $19.25-12.50=6.75 and then you divide that by the number of drinks which would be 6.75/5=$1.35
