Answer:
(a) y = (p - 3x) cm
(b) p = 35 cm
Step-by-step explanation:
Total length of the ribbon = p cm
The length of the first part = x cm
The length of the second part = 2x cm
Let the length of the third part be represented by y.
(a) Thus,
x + 2x + y = p
3x + y = p
y = p - 3x
An expression for the length of the third part is (p - 3x) cm
(b) If x = 10 cm, then;
length of first part = 10 cm
length of the second part = 2x
= 2(10)
= 20 cm
But,
length of the second part = 4y
i.e 20 = 4y
y = 5 cm
The value of p = 10 + 20 + 5
= 35 cm
p = 35 cm

This past winter, 643 flamingos migrated to Gordon Lake. A researcher states that the number of flamingos migrating to the lake is decreasing by 12 birds every year. Which of the following represents the number of flamingos, n, that will migrate to the lake t winters from last winter if the researcher’s trend continues? A. t = 643 - 12n B. n = 643 - 12t C. t = 12 - 643n D. n = 12 - 643t
Answer:
n=643-12t

a number with 2 decimal places, that is bigger than 4 1/5 but smaller than 4.25
Answer:
4.21, 4.22, 4.23,
4.24 (choose any one)
Step-by-step explanation:
since 4 1/5 is 4.20, so the numbers in between 4.20 and 4.25 are 4.21, 4.22, 4.23,
4.24 (choose any one)

Ned types 360 words in 6 minutes. Nate types 220 words in 4 minutes.
Who would type more words in 10 minutes? What assumptions do you
make?
Answer and step-by-step explanation:
We know that Ned types 360 words in 6 minutes while Nate types 220 words in 4 minutes. We are then asked to find out who would type more words in 10 minutes.
To solve this, we need to first reduce the fraction of how many words can be typed to a certain amount of minutes to find how many minutes exactly can Ned and Nate type in one single minute.
Ned types 360 words in 6 minutes, our fraction would be :
[tex]\frac{360}{6}[/tex]
Nate types 220 words in 4 minutes, our fraction would be :
[tex]\frac{220}{4}[/tex]
Now divide both sides by their LCM :
Ned:
[tex]\frac{360/6}{6/6}[/tex]
Nate:
[tex]\frac{220/4}{4/4}[/tex]
Ned :
[tex]\frac{60}{1}[/tex]
Nate:
[tex]\frac{55}{1}[/tex]
This means that in one minute, Ned can type 60 words while Nate can type 55 words. Since we know that 60 is a greater number than 55, we can assume that Ned will type more words than Nate in 10 minutes.

Find the first 6 terms of the sequence.
Step-by-step explanation:
you really need help with that ? it is all already given in the problem description. you only need to do the 6 little calculations (anyways adding 6). what is the problem ?
a1 = 7
a2 = a1 + 6 = well ? ... ... ... 13, of course
a3 = a2 + 6 = 13 + 6 = weeeeelllll ?
a4 = a3 + 6 = 13 + 6 + 6 = weeeellll ?
a5 = a4 + 6 = 13 + 6 + 6 + 6 =
a6 = a5 + 6 = 13 + 6 + 6 + 6 + 6 =
I am really not doing your very basic and just "mechanical" work of doing simple calculations in your head or on your calculator.
I help you, when you have a problem understanding the issue, but not when you ask me to do your pure "mechanical" job that every elementary school student can do easily.
to help with the understanding, such a sequence (using this example) can then be described and every element calculated by
a(n) = a(1) + 6*(n-1)
so, for example
a20 = 7 + 6*19 = 121
so, and now that you truly understand the concept, just use your calculator (if you truly cannot do that in your head) and do your job.
