iren [92.7K]

Answer:

335\:\text{ft}

Step-by-step explanation:

The circumference of a circle is given by C=2\pi r, where r is the radius of the circle. Therefore, we can set up the following equation and solve:

2\pi r=2107,\\r=\frac{2107}{2\pi},\\r\approx \boxed{335\:\text{ft}} (rounded to the nearest foot).

The value of x must be greater than <br> .
iogann1982 [59]

we know that

The <u>Triangle Inequality Theorem,</u> states that the sum of the lengths of any two sides of the triangle is greater than the length of the third side

so

AB+AC > BC\\AB+BC > AC\\AC+BC > AB

we have

AB=12\ units\\AC=15\ units\\ BC=x\ units

substitute the values

12+15 > x ----->x < 27\ units

12+x > 15 -----> x > 3\ units

15+x > 12 -----> x > -3\ units

3\ units < x < 27\ units

therefore

<u>the answer is</u>

The value of x must be greater than 3

85% of what number equals 17

Percent means parts out of 100
85%=85/100=0.85
'of' means multiply

therefor
85% of x equals 17 means
0.85 times x=17
divide both sides by 0.85
x=20



the number is 20
