Answer: $27.50
Step-by-step explanation:
45% = 0.45
$50 × 0.45 = $22.50
$50 - $22.50 = $27.50
Don't worry because I be the dumb too. Me could have been using 0.55 as multiplier but am too dumb so made meself get extra step
Lol
You could have also done:
$50 × 0.55 = $27.50

Answer:
Your answer is <em>8.06</em>.
Step-by-step explanation:
Since you're finding the hypotenuse of the triangle through Pythagorean theorem, you need to use the formula:
a² + b² = c²
Here, you have to remember that x is the same as c in the formula. c is the hypotenuse and x.
a is going to be your smallest leg, so in this case a = 4.
b is going to be your longest leg, so it is b = 7.
Now, you don't know what c yet is so you simply write it as:
4² + 7² = c²
Do the exponents.
16 + 49 = c²
Add.
65 = c²
Now you need to get the exponent away from the c. To do that, all you have to do is square root both sides.
√65 = √c2
Once you do that, you have your answer!
<u>8.0622577483 = c</u>
Now just simplify and you're done :)
<u>8.06</u>

Might sound hard now but you'll get the hang of it.
keeping in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
