The answer to ur problem is 15 x
Take a look at the diagram below.
This problem looks like a great candidate for using the Law of Cosines.
If you know two sides, you can find the third side from the angle opposite or vice versa. Should the sides be a, b, and c, and their opp. angles A, B, and C...
a² + b² - 2ab(cosC) = c²
Let's plug in what we know...a = 55, b = 25, and m<C = 25".
55² + 25² - 2(55)(25)(cos(25")) = c²
One thing to note is that our angle measure is in <em />seconds. Unless you're using Google's built in calculator, you'll wind up having to convert to degrees. 60 seconds in a minute, 60 minutes in a degree...blahblahblah.
Anyways, cos(25") comes out to be practically 1. (0.99999993)
Let's get evaluating.
3025 + 625 - 2750(1) = c²
3025 + 625 - 2750 = c²
900 = c²
30 = cThe tree is

Answer:
43 1/3 minutes to iron 10 shirts
Step-by-step explanation:
Number of shirts : Time taken
3 shirts : 13 minutes
10 shirts : x minutes
3 / 13 = 10 / x
Cross product
3 * x = 13 * 10
3x = 130
Divide both sides by 3
3x / 3 = 130 / 3
x = 43 1/3 minutes
x = 43 minutes 20 seconds
It will take 43 minutes 20 seconds to iron 10 shirts
In the case of Irina shown below, the rule for this translation that is best is T-3, 2(x, y).
<h3>What is the translation about?</h3>
Note that we know that the tile floor is said to be shifted or moved to the left hand side by 3 units, and also it was moved up by 2 units (See image).
Therefore, this can be shown as:
(x,y) -> (x - 3, y + 2)
This in another method can also be written as:
T -3,2 (x,y)
Therefore, we can say that the translation rule is T -3,2 (x,y)

Answer:
$333.5
Step-by-step explanation:
First we have to find 45% of 230 and then add that value to 230
(we can also find 145% of 230, which is essentially the same thing)
so 45% of 230 is:
230*(45/100)= $103.5
230+103.5= $333.5
