Answer: x=0.6 btw how do you put a picture into a question.
Answer:
1a) t = 0.17b
1b) $36.03
2) 51,167.50
Step-by-step explanation:
1a) 17% converted to a decimal (divide by 100) = 0.17. Multiply that by the amount of the bill (before tipping) to get the amount of the tip
1b) The bill of $248 represents the entire bill (100%) plus the tip amount (17%) which makes 117%. As a decimal, this is 1.17.
To find what the cost was without the tip, divide the bill total by 1.17
248/1.17 = 211.97. That was the bill before the tip was added.
248-211.97 = 36.03 was the tip added.
2) 5.5% converted to a decimal is 0.055
0.55 x 48,500 = 2667.50
$2,667.50 + $48,500 = 51,167.50
Or, you can use what we did in 1b, and his new salary is 1.055 times 48,500
1.055 x 48,500 = 51,167.50

here is the answer
Answer:
a
Step-by-step explanation:
Given end points of diameter,
(x1,y1)=(-3,-4)
(x2,y2)=(0,0)
Now,
the equation of circle is,
(x-x1)(x-x2)+(y-y1)(y-y2)=0
or, (x+3)(x-0)+(y+4)(y-0)=0
or, x^2 +3x +y^2 +4y =0
or, x^2 +y^2 +3x + 4y=0
which is in the form of x^2 +y^2 +2gx +2fy + c=0
where,
g=3/2
h=2
c=0
Now,
![radius(r) = \sqrt{ {g}^{2} + {f}^{2} - c } \\ = \sqrt{ \frac{ {3}^{2} }{ {2}^{2} } + {2}^{2} - 0 } \\ = \sqrt{ \frac{9}{4} + 4} \\ = \sqrt{ \frac{25}{4} } \\ = \frac{5}{2}](https://tex.z-dn.net/?f=radius%28r%29%20%3D%20%20%5Csqrt%7B%20%7Bg%7D%5E%7B2%7D%20%20%2B%20%20%7Bf%7D%5E%7B2%7D%20-%20c%20%20%7D%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%20%5Cfrac%7B%20%7B3%7D%5E%7B2%7D%20%7D%7B%20%7B2%7D%5E%7B2%7D%20%7D%20%2B%20%20%7B2%7D%5E%7B2%7D%20%20-%200%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%20%5Cfrac%7B9%7D%7B4%7D%20%20%2B%204%7D%20%20%5C%5C%20%20%3D%20%20%20%5Csqrt%7B%20%5Cfrac%7B25%7D%7B4%7D%20%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B5%7D%7B2%7D%20)
