Mr pilgrim needs fencing for his turkey coop the perimeter is 240 yards the length is 16 yards longer than the width
Answers
Based on the information given, the length will be 68 yards while the value of the width will be 52 yards.
Width = wLength = w + 16The calculation will go thus:
Perimeter = 2l + 2w
240 = 2(w + 16) + 2w
240 = 2w + 32 + 2w
240 = 4w + 32
4w = 240 - 32
4w = 208
w = 208/4 = 52
Therefore, the length will be:
= w + 16 = 52 + 16 = 68

Answer:
1/20 E
Step-by-step explanation:
11.74 - 11.69 = .05
.05 =1/20
Answer:
E. 1/ 20 seconds
Step-by-step explanation:
The distance covered by both the athletes is the same.
So, calculating the difference between their times:
Bryan completed the race in 11.74 secondsLuis completed the race in 11.69 secondsDIFFERENCE:That means, Luis completed the race before Bryan, and the difference between their times is:
= 11.74 - 11.69
= 0.05 seconds
CONVERSION:To convert this decimal into a fraction we'll multiply and divide the decimal by 100 (as the number of decimal places is "2", the decimal will be handled by 10 exponent "2" )
[tex]=0.05 \times \frac{100}{100}[/tex]
[tex]= \frac{5}{100}[/tex]
5's a common factor in both numerator and denominator hence, it cancels out
[tex]=\frac{1}{20}[/tex]
ANSWER:Therefore, we got [tex]\frac{1}{20}[/tex] seconds. That is option E.

30 min = ½ hr.[tex]\implies \footnotesize \text{ Average Speed} = \dfrac{ 6.7 \: km}{ \frac{1}{2} \: hr }[/tex]
[tex]\implies \footnotesize \text{ Average Speed} = 6.7 \times 2 \: km/h[/tex]
[tex]\implies \footnotesize \textbf{ Average Speed = 13.4 \: km/h}[/tex]
His rate is 13.4km/ hour
Data;

[tex]60min =1 hour\\[/tex]
Since his rate is 6.7kmin 30 minutes, let's convert it to hour
[tex]6.7km = 30min\\x km = 1min\\x = \frac{6.7}{30} \\x = 0.223km/min[/tex]
But to convert minutes to hours, we have to divide the time by 60

A local store is selling fresh tuna. The table below shows the price for the amount of tuna. Amount of tuna (in pounds) 2, 6, 7 price (in dollars) 12, 30, 35.
predicted price for 9 pounds of tune?
Answers
Answer:
Its not always the same, 45 dollars
Step-by-step explanation:
Here is why its not always the same:
12/2 = 6 dollars/pound
30/6 = 5 dollars/pound
35/7 = 5 dollars/pound
we can see that they are not the same price as they vary.
For 9 pounds we can assume that the price would continue to be 5 dollars/pound:
x/5 = 9
x=5*9
x= 45

solving systems of equations in three variables
Answers
Answer:
Option B: (x= -8, y=10, z=-6)
Step-by-step explanation:
2x + 4y + 3z = 6 ... eq.(1)
5x + 8y + 6z = 4 ... eq.(2)
4x + 5y + 2z = 6 ... eq.(3)
From eq.(1),
2x= 6 - 4y - 3z
x= (6-4y-3z)/2 ... eq.(4)
Putting x as (6-4y-3z)/2 in both eq.(2) and eq.(3)
In eq.(2),
5[(6-4y-3z)/2] +8y +6z =4
Multiplying through by 2
5(6-4y-3z) + 16y + 12z = 8
30-20y-15z+16y+12z = 8
22= 4y + 3z ... eq(5)
In eq.(3),
4[(6-4y-3z)/2] +5y +2z = 6
2(6-4y-3z) +5y + 2z =6
12-8y-6z + 5y +2z = 6
6= 3y + 4z ... eq.(6)
Multiplying eq.(5) and eq.(6) by 3 & 4 respectively
66=12y + 9z ... eq(8)
24=12y + 16z ... eq(9)
Subtracting eq(8) from eq(9)
42= -7z
z= -42/7
z = -6
Putting z as -6 in eq.(5)
22= 4y + 3(-6)
22= 4y -18
4y = 40
y = 40/4
y = 10
Putting y as 10 and z as -6 in eq(4)
x = [6 - 4(10) - 3(-6)]/2
x = (6 - 40 - 18)/2
x = -16/2
x = -8
x= -8, y= 10 , z= -6
There are 495 pages in the mathematic book, from this 330 pages are included for the first term. Find the proportion of total pages to allotted pages in simplest form.
Answers
Answer:
330/495 = 2/3
the answer is 2/3
Answer:
3 : 2
Step-by-step explanation:
Total pages : allotted pages = 495 : 330
Find the HCF of 495 and 330
495 = 5 * 3*3*11
330 = 5 * 3 * 2 * 11
HCF = 5 * 3 * 11 = 165
Divide 495 and 330 by 165
495 : 330 = 3 : 2

find the 6th term of geometric sequence whose common ratio is 3/2 and whose first term is 2
Answers
Answer:
243/16
Step-by-step explanation:
we have a1 = 2
r = 3/2
n = 6
The 6th term of the geometric sequence is 243/16
The given parameters are:
[tex]a = 2[/tex] --- the first term
[tex]r = 3/2[/tex] --- the common ratio
The nth term of a geometric sequence is:
[tex]T_n = ar^{n-1[/tex]
So, the 6th term would be:
[tex]T_6 = 2 \times (3/2)^{6-1[/tex]
Subtract 1 from 6
[tex]T_6 = 2 \times (3/2)^5[/tex]
Evaluate the exponent
[tex]T_6 = 2 \times (243/32)[/tex]
Simplify
[tex]T_6 = 243/16[/tex]
Hence, the 6th term of the geometric sequence is 243/16
