Answer:
1/2
Step-by-step explanation:
because there are 2 cards and you are going to get one of them so the probability is a half
Answer:
47°
Step-by-step explanation:
if it is the same, then the angles are the same
180 - 85 - 48 = 47
the answer choices don't make sense but I can help u with solving the equation it's x = 1
- 3x-12=-9 , minus 12 on both sides
- 3x = 3 , divide 3 on both sides
- x = 1
now that u know this go through your answer choices and solve their equation and see which one produces x = 1 and that'll be the answer!!
This equal the base * height
= 14.2 * 7.18
= 101.956 cm^2 (answer)
The width of the border will be about 2.5 feet.
The area of the rug is 9 by 7. Let's call the width of the border x. Therefore, the length of the rug will switch to 9 + 2x. The border is on both sides of it, so we add on 2x. Then, the width is 7 + 2x.
The area of the room is therefore: (9 + 2x)(7+ 2x).
We know the area of the room, so we can write and solve the following equation.
(9 + 2x)(7 + 2x) = 167
4x^2 + 32x + 63 = 167
4x^2 + 32x - 107 = 0
At this point, use the quadratic formula and x will equal about 2.5.
