Which monomial is a perfect cube? 49p9q3r24 81p12q15r12 121p9q3r6 343p6q21r6.
Makovka662 [10]

The monomial is a perfect cube is \rm 343p^6q^{21}r^6.

<h3>Perfect cubes;</h3>

Perfect cubes are the numbers that are the triple product of the same number.

We have to determine

Which monomial is a perfect cube?

A perfect cube monomial must have three identical roots, such that the product of the roots equals the perfect square monomial.

It must be possible for the coefficient of a perfect cube monomial to be written in the form n3, where n equals the cube root of the coefficient.

A perfect cube monomial must have exponents on the variables.

Then

The monomial is a perfect cube is;

\rm= 343p^6q^{21}r^6\\\\= \sqrt[3]{  343 }= 7

Hence, the monomial is a perfect cube is \rm 343p^6q^{21}r^6.

Step-by-step explanation:

  • right triangle is A right triangle or right-angled triangle is a triangle in which one angle is a right angle
  • acute triangle is An acute triangle is a triangle with three acute angles. An obtuse triangle is a triangle with one obtuse angle and two acute angles
  • obtuse triangle is An obtuse triangle is one that has an angle greater than 90°. Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). It's impossible for a triangle to have more than one obtuse angle.

Find the area of the unshaded region for these two problems​
Grace [21]

1. Area of the right angled ∆ = 1/2 × base × height

height = 16m

base = √20² – 16²

= √400 –256

= √144

= 12 m

Area of the unshaded portion

= 1/2 × base × height

= 1/2 × 12 × 16

= 96m²

2. Area of the rectangle = 300ft × 150ft

= 45000sq. ft

Area of the shaded portion = 100² + (1/2×b×h)

= 10000 + (1/2×120×150)

= 10000 + 9000

= 19000 sq. ft

Area of the unshaded part of the rectangle

= (45000 – 19000)sq. ft

= 26000 sq. ft

Brian invests £1800 into his bank account.
SVEN [57.7K]

Step-by-step explanation:

\underline{ \underline{ \text{Given}}} :

  • Principal ( P ) = £ 1800
  • Rate ( R ) = 5%
  • Time ( T ) = 3 years

\underline{ \underline{ \text{To \: find}}} :

  • Total amount

\underline{ \underline{ \text{Solution}}}:

First , finding the amount of interest :

\boxed{ \sf{Interest =  \frac{PTR}{100}}}

⇢ \sf{Interest =  \frac{1800 \times 5 \times 3}{100}}

⇢ \sf{Interest =  \frac{27000}{100}}

⇢ \sf{Interest = £ 270}

Now , Finding the total amount :

\boxed {\sf{Total \: amount = Principal + Interest}}

⇢ \sf{Total \: amount = 1800 + 270}

⇢ \sf{Total \: amount   =  \: £ 2070}

\red{\boxed{ \boxed{ \tt{Our \: final \: answer : brian \: will \: have £ 2070 \: after \: 3 \: year.}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ
