Answer:
hope it helps...
Step-by-step explanation:
Mathematicians Marijn Heule from the University of Texas, Victor Marek from the University of Kentucky, and Oliver Kullmann from Swansea University in the UK teamed up to figure it out, feeding a number of different techniques into University of Texas’s Stampede supercomputer and letting it narrow down the number of colour combination possibilities from 102,300 trillion (that’s 102,300) to just 1 trillion.
Answer:
B
Step-by-step explanation:
Given
2x² - 4x = 14 ( divide through by 2 )
x² - 2x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 7 + 1
(x - 1)² = 8 → B
For number 1 ↓
A) Cards increase the score by 8 points → <span>5 + 3; 4 + 4</span>
B)Cards decreased the score by 9 points→ <span>-29 + 20; -2 +-7</span>
C) Removing cards that increase the score by 10 points → <span>-4 + -6 & -5 + -5 </span>
D. Positive cards that decrease the score by 18 points. → Well since their aren't "positive card" that'll decrease the score. It might be negative cards which will decrease the scores
For number 2 ↓
Number of Cards → 5 | -3 | -4 | 3|
New cards: 5 | -12 | 4 | 3|
5 + -12 + -4 + 3 = -8
For number 3.↓
12: |-6 | -6|
8: |4 | 4 |
So, the numbers of "cards" hand would: -6 | -6 | 2 | 2| 2| 2 | ; 4| 4
Answer:
The answer to your question is 9 gallons
Step-by-step explanation:
Data
height = 20 ft
perimeter = 147 ft
1 gallon covers 300 ft²
paint = ?
Formula
Area of a cylinder = 2πrh + πr²
2πr = 147 ft
r = ?
Process
1.- Calculate the radius
2πr = 147
r = 147/2π
r = 23.4 ft
2.- Substitution
Area of the cylinder = 147(20) + 3.14(23.4)²
3.- Simplification
Area of the cylinder = 940 + 1719.33
Area of the cylinder = 2659. 33 ft²
4.- Divide the area of the cylinder by the area a gallon can cover.
Number of gallons = 2659.33/300
= 8.86 ≈ 9
