Answer:
22
Step-by-step explanation:
A square has 4 equal diagonals
And the perimeter of a square is 4L(length)
So the equation will be
=>Perimeter (P) =4L(length)
=>88=4L
=><u>88</u>=<u>4L</u>
4. 4
=>the 4 will divide the 88 to get 22
=>L=22cm
Answer:
( , 8 )
Step-by-step explanation:
y = 8x + 6 → (1)
y = 32x → (2)
substitute y = 32x into (1)
32x = 8x + 6 ( subtract 8x from both sides )
24x = 6 ( divide both sides by 24 )
x = =
substitute this value into either of the 2 equations and solve for y
substituting into (2)
y = 32 × = 8
solution is ( , 8 )
Answer:
132 cm cubed
Step-by-step explanation:
so if = 3
cylinder 1 = 3 x 2 x 2 x 7 = 84 cm cubed
cylinder 2 - 3 x 4 x 4 x 1 = 48 cm cubed
all together = 84 + 48 = 132 cm cubed
area of this object = 132 cm cubed
We can start this problem by finding out what the lowest consecutive number's value is (x). Since consecutive numbers are numbers that are 1 apart from each other, the sum of 9 consecutive numbers would look like
x + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) + (x+6) + (x+7) + (x+8)
Since we know that they equal 153,
x + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) + (x+6) + (x+7) + (x+8) = 153
Now we combine like terms
9x + 36 = 153
Simplify
9x = 117
x = 13
Now, we need to find what the 5th consecutive number is equal to. The fifth consecutive number is (x+4), so 13 + 4 is 17, meaning that the 5th of 9 consecutive numbers that add up to 153 is 17.
