Answer:
Mariana takes the two pills together after 18 hours.
Step-by-step explanation:
Mariana must take two pills; one every 6 hours and another every 9 hours.
She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.
To find the time to take the two pills together, take the least common multiple of 6 and 9.
6 = 2 x 3
9 = 3 x 3
So, the least common multiple is 2 x 3 x 3 = 18
So, she takes the two pills together after 18 hours.
Ramesh went from place A to place B and then from place B to place CA is 10.8 km from B and place B is 15.5 km from place C, Rahul went from place A to place D and then place D to place C, distance between place A and D is 11.7 km and distance between place D and place C is 18.2 km, Who travelled more distance and by how much, also calculate the total distance between place A and place D and express the total distance in M,CM and KM.
Answer:
Part A
Rahul by 3.6 km
Part B
The distance between A and D, through place C, d are;
The distance between A and D in meters, m = 44,500 m
The distance between A and D in centimeters, cm = 4,450,000 cm
The distance between A and D, in kilometers, km = 44.5 km
Step-by-step explanation:
Part A
The details of the journeys are;
The distance of A from B = 10.8 km
The distance of B from C = 15.5 km
The total distance Ramesh traveled, d₁ = The distance of A from B + The distance of B from C
Therefore;
d₁ = 10.8 km + 15.5 km = 26.3 km
The total distance Ramesh traveled, d₁ = 26.3 km
The distances of the journey of Rahul is as follows;
The distance between place A and D = 11.7 km
The distance between place D and C = 18.2 km
The total distance Rahul traveled, d₂ = The distance between place A and D + The distance between place D and C
d₂ = 11.7 km + 18.2 km = 29.9 km
The total distance Rahul traveled, d₂ = 29.9 km
Therefore, given that d₂(29.9 km) > d₁(26.3 km), Rahul travelled more distance than Ramesh
The difference between the distance Rahul travelled and the distance Ramesh travelled, d₂ - d₁ = 29.9 km - 26.3 km = 3.6 km
Therefore;
Rahul travelled more distance than Ramesh by 3.6 km
Part B
The total distance from place A to place D through place C, d₃, is given as follows;
d₃ = The distance from A to B + The distance from B to C + The distance from C to D
∴ d₃ = 10.8 km + 15.5 km + 18.2 km = 44.5 km
The total distance from place A to place D, d₃ = 44.5 lm
The total distance from place A to place D in meters, m = 1000 m/km × 44.5 km = 44,500 m
The total distance from place A to place D in cm = 100 cm/m × 44,500 m = 4,450,000 cm

Luce is single and making $763 biweekly. She claims no federal withholding allowances. If the state tax is 19% of the federal tax, how much in state tax does Luce contribute? a.
$12.92
b.
$15.13
c.
$15.77
d.
$16.34
Answer: d. $16.34
Step-by-step explanation:
The table shows that if the wages are between 760 and 780 and there are no withholding allowances, the federal tax is $86.
Luce therefore has a federal tax of $86 as she falls in the bracket described.
If state tax is 19% of this, state tax is:
= 19% * 86
= $16.34
The amount of state tax which is contributed by the Luce for the no federal withholding allowances is $16.34.
What is federal income tax?Federal income tax is the tax which is used to develop and run the city or country and charged on the citizen residing there .
A 9-column table with 7 rows is given in the prooblem.
Luce is single and making $763 biweekly. She claims no federal withholding allowances.
This amount is come between the values of $760 and $780. If we look into the table provided into the problem, the federal tax for this slab is $86.
Now the state tax is 19% of the federal tax. Thus, the 19 percent of the federal tax $86 is,
[tex]\rm tax=86\times\dfrac{19}{100}\\tax=16.34[/tex]
Thus the amount of state tax which is contributed by the Luce for the no federal withholding allowances is $16.34.

An exam has 20 exercises.For every exercise solved correctly you get 8 points and for every exercise solves wrong are taken off 5 points.Ben had 13 points.How many exercises did he solve?
Answer:
13 exercises
Step-by-step explanation:
The number of exercises in the exam = 20
The points received for questions solved correctly = 8 points
The points taken off for exercises solved wrong = 5 points
The number of points Ben has = 13 points
Let 'c' represent the number of exercises he solved correctly and let 'w' represent the number of exercises he solved wrong, we have;
0 < c + w ≤ 20...(1)
8·c - 5·w = 13...(2)
Given that 5·w has either a 0 or 5 as the unit digit, and x3 = x8 - 5, such as 13 = 18 - 5, we have that the last digit of 8·c is 8, and the last digit of 5·w is 5
The products of 8 with '8' as the unit are, 8 × 6, 8 × 11, and 8 × 16
Therefore, when c = 6, and w = 7, we get;
8 × 6 - 5 × 7 = 13
The number of exercises Ben solved, c + w = 6 + 7 = 13 < 20
When c = 11, we get;
8 × 11 - 5 × 15 = 13
11 + 15 = 26 > 20
The number of exercises Ben solved = 13 exercises
George earned $3,200 for one month of work. He paid $640 in income tax for the month. What percent tax did he pay? (Ignore the percent sign when gridding your answer.
Answer:
He paid $640 out of his total $3,200 for the month.
As a fraction it is (640/3200) which equals (1/5)
We want it as a percentage so we multiply the fraction by 100.
1/5×100=20%
20% is the final answer.

14. A polygon ABCD is inscribed in a circle. Find angle ABC
15. A polygon GHIJ is inscribed in a circle if GHI=76 and HIJ=66 what is IJG
Answer:
m<ABC = 100degrees
m<IJG = 104degrees
Step-by-step explanation:
14. The sum of the opposite angle of the quadrilateral is 180degrees. Hence;
m<ADC + m<ABC = 180
3y+8+4y+4 = 180
7y + 12 = 180
7y = 180 - 12
7y = 168
y = 168/7
y = 24
Get <ABC
m<ABC = 4y+4
m<ABC = 4(24) + 4
m<ABC = 96 + 4
m<ABC = 100degrees
15. Similarly for this;
GHI + IJG = 180
76 + m<IJG = 180
m<IJG = 180 - 76
m<IJG = 104degrees

x = 8
Step-by-step explanation:
Given 2 intersecting chords.
Then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
14(2x + 2) = 12(2x + 5) ← distribute parenthesis on both sides
28x + 28 = 24x + 60 ( subtract 24x from both sides )
4x + 28 = 60 ( subtract 28 from both sides )
4x = 32 ( divide both sides by 4 )
x = 8
