Answer:
π-2 ,√2, √10–2, e-1 and the Golden Ratio Φ which equals (√5+1)/2.
Answer:
93,675
Step-by-step explanation:
We see that the given sequence is an arithmetic sequence with first term 997, common difference -5, and last term 252.
The number of terms in the sequence (n) can be found from the formula for the n-th term:
an = a1 +d(n -1)
(an -an)/d +1 = n
(252 -997)/(-5) +1 = n = 150
The sum of these terms is the average of the first and last terms, multiplied by the number of terms:
S150 = (997 +252)/2·150 = 93,675
The sequence sum is 93,675.
Answer:
x = -7
Step-by-step explanation:
8x - 9 = 12 + 11x
Subtract 11x to both sides of the equation. Then, it will look like this:
-3x - 9 = 12
Add 9 to both sides of the equation. After that, it will look like this:
-3x = 21
Divide both sides of the eqution by -3. Your answer is:
x = -7

0.2 x 1120 = 240 + 1120
The coefficient 3 means the length is 3 times the width ⇒ B
Step-by-step explanation:
The formula of the area of a rectangle is A = l × w, where
- l is the length of the rectangle
- w is the width of the rectangle
∵ The width of the rectangle is x
∴ w = x
∵ The length of the rectangle is 3x
∴ l = 3x
- That means the length of the rectangle is 3 time the width
because x × 3 = 3x
∴ Area of the rectangle is A = 3x × x
∵ x × x = x²
∵ 3 × 1 = 3
∴ A = 3x²
∴ The coefficient 3 means the length is three times the width
The coefficient 3 means the length is 3 times the width
