What makes b in the equation true 3/8 X 8/b

Mathematics
1 answer:
Gala2k [10]4 years ago
8 0

\frac{3}{8} *  \frac{8}{b} =  \frac{3}{1} *  \frac{1}{b}  (I crossed simplify)

Next cross multiply;

3b = 1

b = 1/3

To check if the statement is true just substitute the value of b in the equation;

3b = 1

3(1/3) = 1

1 = 1

Here's the question ​
zheka24 [161]

Answer:

60

Step-by-step explanation:

perimeter (p) = 8 + 17 + 15 = 40

semi-perimeter (s) = p/2 = 20

Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.

Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60

Someone help with this midpoint question please
Natali5045456 [20]

Answer: D) (2,0)

Step-by-step explanation:

These are your values.

(-2,4);(6,-4)

Remember this means;

(x_1,y_1);(x_2,y_2)

The formula for finding the midpoint of a segment is simple. Add both x's and y's and divide them by 2 separately. Or, if you like to follow formulas, here you go.

Let M be midpoint.

M=\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}

M=\frac{-2+6}{2},\frac{4+(-4)}{2}

M=\frac{4}{2} ,\frac{4-4}{2}

M=\frac{4}{2} ,\frac{0}{2}

M=2,0
