Answer:
Yes
Step-by-step explanation:
It not a continues number like 1.33333... therefore it is rational. If it went on forever it would be concidered irrational.
Answer:
Yes. 5.67 is a rational no.
Step-by-step explanation:
5.67 is a terminating & non-repeating decimal . And we know that a terminating non-repeating (or repeating i.e. the decimal would have a bar) decimal no. is a rational number.
5.67 can also be written as [tex]\frac{567}{100}[/tex] . A rational is always in the form of [tex]\frac{p}{q}[/tex] form where p & q are integers. Hence 5.67 is a rational number.
Parker signed up for a streaming music service that costs $6 per month. The service
allows Parker to listen to unlimited music, but if he wants to download songs for
offline listening, the service charges $0.50 per song. How much total money would
Parker have to pay in a month in which he downloaded 50 songs? How much would
he have to pay if he downloaded s songs?
Answer:
Parker will have to pay $31 in a month in which he downloaded 50 songs.
Total amount Parker will pay for s songs = 6 + 0.50s
Step-by-step explanation:
Cost per month = $6
Cost of Offline download = $0.50 per song
A. How much total money would
Parker have to pay in a month in which he downloaded 50 songs?
Total amount Parker will pay = $6 + $0.50(50)
= 6 + 25
= $31
Parker will have to pay $31 in a month in which he downloaded 50 songs.
B. How much would
he have to pay if he downloaded s songs?
Total amount Parker will pay for s songs = $6 + $0.50 * s
= $6 + $0.50s
Total amount Parker will pay for s songs = 6 + 0.50s
Solve for n 19 + 10n = 7n - 20
Answer:
n = -13
Step-by-step explanation:
19 + 10n = 7n - 20
Subtract 7n from each side
19 + 10n-7n = 7n-7n - 20
19+3n = -20
Subtract 19 from each side
19+3n -19 = -20-19
3n = -39
Divide each side by 3
3n/3 = -39/3
n = -13
if the whole numbers are added the sum would be
113.5+22.41
a rectangle with sides of length n+2 and n is compared to a square with sides of length n+1 are the two shapes equal in perimeter?
Answer:
yes
Step-by-step explanation:
Both of the figures have the same perimeter (4n + 4) hence equal in perimeter,
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
We know the perimeter of a rectangle is 2(length + width) and the perimeter of a square is 4×side.
Given, A rectangle with sides of length n+2 and n.
∴ Perimeter = 2((n + 2) + n)
= 2(2n + 2).
= 4n + 4.
Also given, A square with sides of length n + 1.
∴ Perimeter = 4(n + 1).
= 4n + 4.
So, yes the two shapes are equal in the perimeter.

Your temperature is 99 degrees during first period. By 7th period,your temperature is 102 degrees. How many degrees did your temperature change? Should you be at school.?
Given :
Temperature at first period , [tex]T_1=99^oF[/tex] .
Temperature at seventh period , [tex]T_7=102^oF[/tex] .
To Find :
The change in temperature .
Solution :
We know , change in temperature is given by the difference between final and initial temperature .
[tex]\Delta T=T_7-T_1\\\\\Delta=(102-99)^oF\\\\\Delta=3^oF[/tex]
So ,the change in temperature is [tex]3^oF[/tex] .
Now , the average body temperature of human body is [tex]98.6^oF[/tex] and [tex]100.4^oF[/tex] is considered a fever .
Therefore , we should not be in school and take rest .
Hence , this is the required solution .

Which table has a constant of proportionality between y and x of 8/5
Answer:
Table 1
Step-by-step explanation:
Constant of proportionality is simply the ratio of y to x. In each of the given tables, the second column is y and the first is x.
Table 1:
4 32/5
10 16
11 88/5
Let's find the constant of proportionality for each row:
R1: (32/5) / 4 = 8/5
R2: 16/10 = 8/5
R3: (88/5) / 11 = 8/5
Thus, since this matches the requirements and all three rows have the same constant, Table 1 is the answer.
If you check the other two tables in the same way, you'll see that neither has a constant of proportionality of 8/5.
Hope this helps!

what is the value of k?
Answer:
k = 10
Step-by-step explanation:
∡ZYX = 180° - 115° = 65° (angles in a line add up to 180°)
*∡ stands for angle.
∑ of ∡Z , Y and X should be equal to 180° (angles in a triangle add up to 180°)
∴ (4k + 5)° + 65° + (6k + 10)° = 180°
10k + 80 = 180
10k = 100
k = 100 ÷ 10 = 10
3(4x-1) greater than or equal to 2(4-x)
Answer:
Greater than
Step-by-step explanation:
First, I solved the expressions.
3(4x-1)=12x-3
2(4-x)=8-2x
12x-3>8-2x
As we can see, 12x-3 is greater than 8-2x.
Step-by-step explanation:
12x - 3 (expand 3(4x-1))
8-2x (expand 2(4-x))
if you assume that x=1 then 12x-3 would be 12(1)-3 then it would be 9 for the first
for the second equation, 8-2x, it would be 8- 2(1) or 6
9>6 so, 3(4x-1) > 2(4-x)

Answer:
Length of route that passes the mall= 11 miles
Length of route that passes the theater= 13 miles
Step-by-step explanation:
route to school that passes the mall (highlighted in red)
= (x +1) +(x +2)
= 2x +3
route to school that passes the theater (in yellow)
= (2x +1) +x
= 3x +1
Since the first is 2 miles shorter,
2x +3= 3x +1 -2
Simplify:
2x +3= 3x -1
Bring constants to 1 side, x terms to the other:
3x -2x= 3 +1
x= 4
Substitute x=4 to find the length of each route:
Length of the route that passes the mall
= 2x +3
= 2(4) +3
= 8 +3
= 11 miles
Length of route that passes the theater
= 3x +1
= 3(4) +1
= 12 +1
= 13 miles
Alternatively, length of route that passes the theater
= 11 +2= 13 miles since it is 2 miles longer than that which passes the mall.

if 17% of a certian num mber of mangoes is egual to 1360 then find total number of mangoesf
Answer:
If you're trying to find the whole number from a percentage of the number, divide the number by its percent: 1360/17%= 8000. The total number of mangoes is 8000.
Step-by-step explanation:
Answer:
[tex]\boxed{\bold{\huge{\boxed{\sf x = 8000 \ mangoes}}}}[/tex]
Step-by-step explanation:
Let the number be x
The given condition is:
=> 17 % of x = 1360
=> [tex]\sf \frac{17}{100} * x = 1360[/tex]
Multiplying both sides by [tex]\frac{100}{17}[/tex]
=> [tex]\sf x = \frac{136000}{17}[/tex]
=> x = 8000
So, total number of mangoes is 8000.

X-5(x-1)=x-(2x-3) what does it equal
Answer:
[tex]x = \frac{2}{3} [/tex]
Step-by-step explanation:
[tex]x - 5(x - 1) = x - (2x - 3) \\ x - 5x + 5 = x - 2x + 3 \\ x - 5x + 2x - x= 3 - 5 \\ - 3x = - 2[/tex]
Divide both sides of the equation by -3
[tex] \frac{ - 3x}{ - 3} = \frac{ - 2}{ - 3} \\ x = \frac{2}{3} [/tex]
160+3x=195-2x what is the answer
Answer:
x = 7
Step-by-step explanation:
160+3x=195-2x
Add 2x to each side
160+3x+2x=195-2x+2x
160 +5x = 195
Subtract 160 from each side
160+5x-160 = 195-160
5x = 35
Divide by 5
5x/5 = 35/5
x = 7
