Which equation shows the inverse property of multiplication?

Mathematics
1 answer:
serious [3.7K]3 years ago
8 0

Answer:

C

Step-by-step explanation:

The options are:

<em>A. 4 + (-4) = 0 </em>

<em>B. -8 + (-3) = -3 + (-8) </em>

<em>C. 2 </em>×<em> 1/2 = 1 </em>

<em>D. 8/5 + 0 = 8/5</em>

<em />

The inverse property of multiplication states that the product of a number and its inverse is one.

The inverse of 2 is 1/2. The multiplication of 2 × 1/2 = 1 , as the property states.

What is 0.91 meter equal to 1 what?
telo118 [61]

Answer:2.986

Step-by-step explanation:

0.91 meter = 2.986 feet

Formula: multiply the value in meters by the conversion factor '3.2808398950132'.

So, 0.91 meter = 0.91 × 3.2808398950132 = 2.986 feet.

0.91 METER TO THE NEAREST FRACTIONS OR INTEGER OF FOOT:

3 feet (e* = 0.48%)

The latest values above are alternative ones for 0.91 meter. They are represented in the form of usable fractions (1

2

, 1

4

, 3

4

etc.) or of an integer. We show these results, when it is possible to convert them to a fraction or integer with a small error e* which means the maximum rounding error (positive or negative).

To calculate a meter value to the corresponding value in feet, just multiply the quantity in meter by 3.2808398950131 (the conversion factor).

Here is the formula:

Value in feet = value in meter × 3.2808398950131

Suppose you want to convert 0.91 meter into feet. Using the conversion formula above, you will get:

Value in feet = 0.91 × 3.2808398950131 = 2.986 feet

Vanessa typically works 8 hours per day in a normal 5 day work week. last week, however, vanessa had to take 90 minutes off on t
Rasek [7]

The total number of hours Vanessa work in a week is:

total work hours = (8 hours / day) * 5 day / week

total work hours = 40 hours per week

The total number of hours she did not work:

<span>total hours did not work = (90 minutes)(1 hour / 60 minutes) + (45 minutes)(1 hour / 60 minutes)  + 2.5 hours</span>

total hours did not work = 4.75 hours

The amount of hours Vanessa work last week can be calculated using the formula:

work hours = total work hours - total hours did not work

work hours = 40 hours – 4.75 hours

<span>work hours = 35.25 hours</span>

If one zero of the following polynomial 8x^2-13x-4k is the reciprocal of the other, then find k
tekilochka [14]

Answer:

k = -2

Step-by-step explanation:

2 way to solve:

1st: 8x²-13x-4k = 8(x²-(13/8)x-(k/2))

if 2 roots: a and 1/a

8(x-a)(x-1/a) = 8(x²-(13/8)x-(k/2))

x²-(a+1/a)x+1 = x²-(13/8)x-(k/2)

1 = -(k/2)

<u>k = -2</u>

<u>2nd:</u> 2 roots of 8x²-13x-4k      x=(-b±√b²-4ac)/2a

x = (13±√169-4*8*(-4k))/16 = (13±√169+128k)/16

(13+(√169+128k))/16 = 16/ (13-(√169+128k))  ... root1=1/root2

(13+(√169+128k))*(13-(√169+128k)) = 16*16

13² - (√169+128k)² = 256

169-169-128k = 256

-128k = 256

k = -2

In the diagram below, quadrilateral ABCD is inscribed in a circle. What is the measure of angle D?
grin007 [14]

Given:

In the circle P, ABCD is inscribed quadrilateral.

And, ∠DAB = 110°, ∠ABC = 72°

To find the value of ∠ADC.

Theorem:

A quadrilateral can be inscribed in a circle if and only if the opposite angles are supplementary [ sum of the opposite angles will be 180°]

According to the theorem,

\angle ABC+\angle ADC = 180^{\circ}

     \angle ADC +72^{\circ} = 180^{\circ}

               \angle ADC = 180^{\circ}-72^{\circ}

               \angle ADC = 108^{\circ}

Hence,

The value of ∠ADC is 108°.

Hence, Option b is the correct answer.
