Answer:
-0.5
Step-by-step explanation:
2^2-3/2-3=4-1.5-3=-0.5
Step-by-step explanation:
The equation that Kaitlyn solved is as follows :
-5.4+x=12.2
The steps to solve it as follows :
Step 1. Add 5.4 to both sides,
-5.4+x+5.4=12.2+5.4
Step 2. 5.4 will cancel out as both have opposite signs
x=17.6
But Kaitlyn solved it as :
5.4.x=6.8
She has multiplied -5.4 and x which is wrong. The correct answer is 17.6.
Answer:
8% increase
Step-by-step explanation:
In this question, we are asked to calculate the percentage increase that a certain increment will give over a period of 10 years.
Let the increment be x
Mathematically from the question, we can obtain that ;
(1+x)^10 = (1+1.2)
(1+x)^10 = 2.2
1+ x = 2.2^1/10
1+x = 1.082
x = 1.082 - 1
x = 0.082
This means that x = 8.2% which is approximately 8%
Answer:
It will cost him $616 for 160 gallons of gas.
Step-by-step EXPLANATION FIRST YOU HAVE TO MULTIPLY 3.25 BY 160 TO GET $520, THEN JUST ADD IT BY $96 TO GET $616.
Answer:
583 miles
Step-by-step explanation:
Let's draw this out (see attachment).
The straight line path creates the hypotenuse of a right triangle with legs of lengths 300 and 500. So, we use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, a = 300 and b = 500. Then:
300² + 500² = c²
90000 + 250000 = c²
340000 = c²
c = √340000 ≈ 583.1 ≈ 583 mi
Thus, the answer is 583 miles.
