9514 1404 393
Answer:
a. x + 4y = 160
b. 160
c. 40
Step-by-step explanation:
a. We can define the variables as ...
x = number of 1/2-liter bottles
y = number of 2-liter bottles
For the total number of liters to be 80, we require
1/2x + 2y = 80
We can multiply this by 2 to eliminate the fraction.
x + 4y = 160
__
b. The x-intercept is 160. It is the number of 1/2-liter bottles required when no 2-liter bottles are used.
__
c. The y-intercept is 40. It is the number of 2-liter bottles required when no 1/2-liter bottles are used.
The answer is B: Y
Y did not change position even after it is reflected
Answer:
The number is 492,875.
Step-by-step explanation:
Given:
A number that is = 
Place value of 4 = 
Place value is ten thousands.
We have to identify the number where the place value of 4 is 10 times of the given number.
Numbers given:
284,796 or 327,498 or 492,875 and 742,186.
Lets see the place value of 4 in each of the number.
⇒
-
place value of
is
. - Place value of 4 is thousands.
⇒
place value of
is
.- Place value of 4 is hundreds.
⇒
place value of
is
.- Place value of 4 is hundred thousands.
⇒
place value of
is
.- Place value of 4 is ten thousands.
Notes:
Ten thousands multiplied with ten is hundreds thousand.
⇒ 
So,
The number which has digit 4 as hundred thousands place values is 492,875.
The magnification factor is given as

. Therefore multiplying this by the spider's actual length will give its apparent length.

This gives an apparent length of 12,000 mm.
Since 1,000 mm = 1 m, this apparent length is also equivalent to 12 m.
