Which of the following statements uses the multiplicative identity?
Roman55 [17]

Answer:

(-8)(1) = -8

Step-by-step explanation:

The expression that uses utilizes a multiplicative inverse is (-8)(1) = -8

A multiplicative inverse is such that when an identity element such as the number 1 multiplies another, it does not change it in any way.

    The expression where we see this is the option C;

          (-8)(1)   -8 multiplied by 1 does not change -8, it is still -8.

A+b+c=24. <br> 30a=40b=24c
liberstina [14]

30a=24c\ \ \ \ \ |:30\\\\a=\dfrac{24}{30}c\\\\a=\dfrac{4}{5}c\\\\40b=\dfrc{24}{c}\ \ \ \ |:40\\\\b=\dfrac{24}{40}c\\\\b=\dfrac{3}{5}c

substitute to a + b + c = 24

\dfrac{4}{5}c+\dfrac{3}{5}c+c=24\ \ \ \ |\cdot5\\\\4c+3c+5c=120\\\\12c=120\ \ \ |:12\\\\\boxed{c=10}\\\\a=\dfrac{4}{5}c\to a=\dfrac{4}{5}\cdot10=\to\boxed{a=8}\\\\b=\dfrac{3}{5}c\to b=\dfrac{3}{5}\cdot10\to\boxed{b=6}

A point is randomly chosen in the diagram shown below.
Anni [7]

Answer:

The likelihood that a point chosen inside the square will also be inside the circle: 78.54%

Step-by-step explanation:

  • Let x is the side of the suqare

=> the area of the square is: x^{2}

  • Let d is the diameter of the circle

=> the area of the circle : \frac{1}{4} d^{2}π

However, d=x because of the square property  

<=> the area of the circle : \frac{1}{4} x^{2}π

The likelihood that a point chosen inside the square will also be inside the circle:

the area of the circle / the area of the square

= \frac{1}{4} x^{2}π / x^{2}

= \frac{1}{4} π *100%

= 0.7854 * 100%

= 78.54%
