1/4 I believe this is the answer sorry if it’s not
X=5 is a definite answer and one solution. While X greater than OR equal to 5 means that it could be 5 AND anything above 5, which gives multiple of choices for solutions. (I believe this write but it’s been awhile since I did algebra stuff)
We have:
- 49KN = 49 × 1000 = 49000N
- 1 foot² = 30² = 900 cm²
So: 49KN/foot² = 49000N/900 cm² = 54,5 N/cm²
P/s: 1 KN = 1000 N
ANSWER: 54,5 N/cm²
Ok done. Thank to me :>
Answer:
y = $2.5x, where "x" is the number of drinks.
Step-by-step explanation:
Step 1: Let "x" be the number of drinks and "y" be the cost.
Step 2: The cost of a drink = $2.5
Now we can find the cost for "x" drinks.
y = $2.5x.
Hope you will understand.
Thank you :)
1. Since we have <span>two sides (AC and AB) and the included angle (60°), we are going to use the law of cosines to find the length of BC:
</span>
<span>
We can conclude that the length of the side BC is </span>
.
2. To find the area of triangle ABC we are going to use Heron's formula:
where
is the area of the triangle
is the semi-perimeter of the triangle
But first, we are going to find the semi-perimeter of our triangle using the formula:
We can infer for our triangle and from our previous calculation that
,
, and
. Lets replace those values to find the semi-perimeter of our triangle:
Finally, we can use Heron's formula to find the area of our triangle:
We can conclude that the area of our triangle is
10.42 square units.
