Write -6/11 * 3/4 lowest terms​

Mathematics
1 answer:
Andrej [43]3 years ago
7 0

Answer:

(-\frac{6}{11})  \times( \frac{3}{4}) = -(\frac{9}{22} )  in the lowest terms.

Step-by-step explanation:

Here, the given expression is : (-\frac{6}{11})  \times( \frac{3}{4})

Solving the given expression, we get:

(-\frac{6}{11})  \times( \frac{3}{4})  = \frac{-6 \times 3}{11 \times 4}   =- \frac{18}{44}

Now, to express the fraction into lowest terms

18 = 2 x 3 x 3,                       44  =  2  x 2 x  11

So, -\frac{18}{44}  = -(\frac{2 \times 3 \times 3}{2 \times 2\times 11} )  = -(\frac{9}{22} )

Hence, (-\frac{6}{11})  \times( \frac{3}{4}) = -(\frac{9}{22} )  in the lowest terms.

Answer:

Step-by-step explanation:

LET ORANGES=X

PEARS ARE 3 TIMES =3X

LET CHILDREN=Y

IF WE GIVE 5 ORANGES PER CHILD WE NEED 5Y ORANGES.SO THIS =X

X=5Y........................I

IF WE GIVE 8 PEARS PER CHILD WE NEED 8Y PERARS...THERE ARE STILL 21 PEARS LEFT OUT AFTER THIS THAT IS

8Y+21=3X....................II

SUBSTITUTING FOR X FROM EQN.I..

8Y+21=3*5Y

15Y-8Y=21

7Y=21

Y=3

X==5Y=5*3=15..

SO CHILDREN =3

ORANGES=15

PEARS=3*15=45

THANKYOU AND PLEASE AMRK IT BRAINLIEST

Cylinders A and B are similar solids. The base of cylinder A has a circumference of 4π units. The base of cylinder B has an area
Alex
The formula for the circumference of a circle is
  C = 2π·r
or
  r = C/(2π)
The radius r of cylinder A is
  r = (4π)/(2π) = 2

The formula for the area of a circle is
  A = π·r²
or
  r = √(A/π)
The radius of cylinder B is
  r = √(9π/π) = 3

The dimensions of cylinder A must be multiplied by 3/2 to produce the corresponding dimensions of cylinder B.

In Rectangle ABCD, m
storchak [24]

Answer:

m∠ACD = 24°

Step-by-step explanation:

Measure of the interior angles of a polygon = \frac{(n - 2)\times 180}{n}

Therefore, measure of the interior angles of a rectangle = \frac{(4 - 2)\times 180}{4}

                                                                                              = \frac{360}{4}

                                                                                              = 90°

m∠BCD = 90°

Since, m∠BCD = m∠BCA + m∠ACD

90° = 66° + m∠ACD

m∠ACD = 90° - 66°

              = 24°

Therefore, measure of angles ACD is 24°.

The frequency of sound varies inversely as the wavelength.
daser333 [38]

Let's assume the frequency of sound be f and wave length is w.

Given that, the frequency of sound varies inversely as the wavelength.

So, we can set up an equation as following:

f*w = k Where k= constant of variation.

Other information is, the frequency of a musical note is 276 cycles per second when the wavelength is 1.2m.

So, next step is to plug in f = 276 and w = 1.2 in the above equation to get the value of k.

276 * 1.2 = k

So, k = 331.2

Next step is to plug in k = 331.2 in the above equation. So,

f * w = 331.2

Now we need to find the wave length : w when frequency : f = 600.

Therefore,

600 * w = 331.2

w = \frac{331.2}{600}

So, w = 0.552

Hence, the wave length is 0.552 m.

Hope this helps you!.
