Mathematics

-5/12 x (6/5 x 1/3) x 9/2 = (-5/12 x 6/5) x (1/3 x 9/2) as said equation correlates with the following formula: (a x b) x c = a x (b x c) where the way you group three or more numbers when adding or multiplying does not change their overall sum or product. Hope this helped! :)

Answer:

C.-\frac{5}{12}\cdot (\frac{6}{5}\cdot (\frac{1}{3})\cdot \frac{9}{2}=(-\frac{5}{12}\cdot \frac{6}{5})\cdot \frac{1}{3}\cdot \frac{9}{2})

Step-by-step explanation:

We have to find the equation in which associative property of multiplication is used.

Associative property of multiplication:

If a, b and c are number

Then, a\cdot (b.c)=(a\cdot b)\cdot c

A.(\frac{-7}{8}\cdot \frac{2}{5})+(\frac{-7}{8}\cdot \frac{3}{5})=-\frac{7}{8}\cdot (\frac{2}{5}+\frac{3}{5})

It is false because distributive property is used not associative property of multiplication.

B.(\frac{-1}{4}-\frac{5}{3})-\frac{3}{5}=-\frac{1}{4}-(\frac{5}{3}-\frac{3}{5})

It is false because associative property of multiplication is not used.

In option C

-\frac{5}{12}\cdot (\frac{6}{5}\cdot \frac{1}{3})\cdot \frac{9}{2}=(-\frac{5}{12}\cdot \frac{6}{5})\cdot (\frac{1}{3}\cdot \frac{9}{2})

It is true because associative property of multiplication is used.

In option D

\frac{-6}{7}\cdot \frac{8}{11}\cdot \frac{1}{3}=\frac{8}{11}\cdot \frac{-6}{7}\cdot \frac{1}{3}

It is not true because commutative property of multiplication is used not associative.

Answer:

\huge\boxed{\sf x = 55\°}

Step-by-step explanation:

When a quadrilateral is inscribed in a circle, the opposite angles of it add up to 180 degrees.

Here,

∠DCB + ∠DAB = 180 (Opposite angles of a quad inscribed in a circle.)

<u>Given that:</u> ∠DCB = 135° and ∠DAB = x

135 + x = 180

Subtract 135 to both sides

x = 180 - 135

x = 55°

\rule[225]{225}{2}

Hope this helped!

In the figure, lines a, b, and c are parallel and m∠4=68° . Drag and drop the correct angle measure for each angle. m∠1 = m∠2 =
melisa1 [442]
The complete question in the attached figure

we have that
<span>m∠4=68°

we know that
</span>m∠4 and m∠3 are supplementary angles
so
m∠3=180-m∠4----- m∠3=180-68------> m∠3=112°

m∠3 = m∠2 --------> by alternate interior angles
so
m∠2=112°

m∠1 = m∠4 --------> by alternate exterior angles
so
m∠1=68°

m∠5 = m∠4---------> by corresponding angles
so
m∠5=68°

the answers are
m∠1=68°
m∠2=112
m∠3=112°
m∠5=68°

Which of the following options results in a graph that shows exponential growth?
poizon [28]

Answer:

f(x)=0.7(5)^x

Step-by-step explanation:

\text{Exponential function: }y=a\cdot b^x

It is two types of function.

  • Exponential Growth: If function increase as value of x increase.

In this case, a>0 and b>1

  • Exponential decay: If function decrease as value of x increase.

In this case, a>0 and 0<b<1

We need to choose exponential growth function.

\text{Exponential Growth function: }f(x)=0.7(5)^x

Here a=0.75>0 and b=5>1

Therefore, This function is exponential growth.
