calculate the exact value of (5/12-11/13)/3/26
Answer:
-67/12168
Step-by-step explanation:
(5/12-11/13)/3/26 Find the least common denominator to get
65/156 - 132/156 = -67/156
-67/156 /3 /26 multiply -67/156 by 1/3 to get -67/468
-67/468 /26 multiply -67/468 by 1/26 to get 12168
-67/12,168

Answer:
C. I,II,III
Step-by-step explanation:
Absolute value is the distance of a number from 0 on a number line. 6 is 6 units from 0, therefore this option is correct. -6 is 5 units to the left of 0, but it is still 6 units away, therefore this option is correct. 6 is 6 units away from 0, therefore, III is correct. But 0 is 0 units away from 0, therefore this option is incorrect.

What is the second number in the sequence?
Answer:
Step-by-step explanation:
Let "n" be the second odd number in the sequence
(n - 2) + n + (n + 2) + (n + 4) + (n + 6) = 135
5n + 10 = 135
5n = 125
n = 25
23 + 25 + 27 + 29 + 31 = 135

if g(n) varies inversely with n and g(n) = 9 when n = 4 then find the value when g(n)=8.
round final answer to the tenths place. if answer is a whole number then put a zero in the tenths place before entering your answer.
Answer:
Step-by-step explanation:
I'm ASSUMING you want to find n where g(n) = 8
g(n) = a/n
g(4) = 9 = a/4
a = 36
g(n) = 8 = 36/n
n = 36/8 = 4.5

When I divide an integer by 15, the remainder is an integer from 0 to 14. When divide an integer by 27, the remainder is an integer from 0 to 26. For instance, if the integer is 100 then the remainders are 10 and 19, which are different. How many integers from 1 to 1000 leave the same remainders after division by 15 and after division by 27?

Find m
∠
K
M
L
∠KML.
Answer:
m∠KML = 35°
Step-by-step explanation:
This is an isosceles triangle because 2 of the sides are equal so we know the 2 unknown angles are equal. The 3 angles of any triangle always add up to 180° so since we know 1 angle is 110° then the 2 unknown angles must add up to 70° (because 180° minus the known 110° leaves us with 70°). Since we know the 2 unknown sides are equal 70° ÷ 2 = 35°. So, m∠KML = 35°
Given the following polynomials
x = (a + b + c)^2
y= a^2 + b^ 2 + C^2
z = ab + bc + ac
Which identity is true?
A. x=y-z
B. x=y+z
C. x=y-2z
D. x=y+2z
Answer:
D. x=y+2z
Step-by-step explanation:
if you expand out the first equation (x) you will get: a^2+b^2+c^2+2ab+2bc+2ac
then looking at all of the choices, it can be seen that the third equation (z) needs to be multiplied by to get 2ab+2bc+2ac and then added to the second equation (y) which would result in D being the correct answer.
D. x=y+2z

The plans for a shed call for a rectangular floor with a perimeter of 186 ft. The length is two times the width. Find the length and width.
Answer:
length: 62 ft
width: 31 ft
Step-by-step explanation:
Let w represent the width. Then the length is 2w and the perimeter is ...
P = 2(L+W)
186 = 2(2w +w)
31 = w . . . . . . . . . divide by 6
2w = 2(31) = 62
The length of the shed is 62 feet; its width is 31 feet.
