Answer:
5) y=5
6)x=7
7)a=18
Step-by-step explanation:
5) y= any number will work. don't add a variable like x
6)x= any number will work. don't add a variable
My work for 7 is in the picture. If you'd like me to explain more for 7 lmk :)
Answer:
The y-intercept is the height of the candle before it was lit
Step-by-step explanation:
The y-intercept is at 0 on the x-axis meaning that not time has passed, so the candle is at its original height
By the Pythagorean Theorem:
h^2=x^2+y^2
Which just means that the hypotenuse (longest side) squared is equal to the sum of the side lengths squared...in this case:
h^2=5^2+13^2
h^2=25+169
h^2=194
h=√194
h≈13.93 in (to nearest hundredth of an inch)
Mckensey is correct as shown above.
Cara's mistake was in letting c be a side length instead of the length of the hypotenuse...
Answer:
<u>6 : 1</u>
Step-by-step explanation:
The length is the longer side compared to the width.
Hence, the length is <u>42 inches</u> and width is <u>7 inches</u>.
<u>Taking the ratio</u> :
- Length : Width
- 42 : 7
- 7 x 6 : 7
- 6 : 1
