Given:

A figure of a rectangular prism with length l, width w and height h.

To find:

The surface area of the rectangular prism.

Solution:

The product of twice of the length l and the width w is:

[tex]2\times l\times w=2lw[/tex]          ...(i)

The product of twice of the length l and the height is:

[tex]2\times l\times h=2lh[/tex]           ...(ii)

The product of twice of the width w and the height h is:

[tex]2\times w\times h=2wh[/tex]       ...(iii)

The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:

[tex]A=2lw+2lh+2wh[/tex]

[tex]A=2(lw+lh+wh)[/tex]

Therefore, the required expression is [tex]2(lw+lh+wh)[/tex].

Answer:

[tex]-8a^{7b}[/tex]

Step-by-step explanation:

[tex](-4 a^{5b}) (2a^{2b}) = -(2^2 a^{5b}) (2a^{2b})\\[/tex]

                    [tex]= -(2 ^2 \times 2) \times a^{5b + 2b}\\\\= -(2 ^{2+1}) \times a^{7b}\\\\=-(2^{3}) \times a^{7b}\\\\= - 8 a^{7b}[/tex]

Answer:

27

Answer: 9/4

Step-by-step explanation: Think of [tex](\frac{4}{9})^{-1}[/tex]as [tex]\frac{4^{-1} }{9^{-1}}[/tex].

Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and

we can change 9⁻¹ to 9¹ by moving it to the numerator.

So we have 9¹/4¹ which simplifies to 9/4.

Explanation:

By definition the perimeter of an object is the length of all its sides.

Also by definition, for a rectangle the 2 sides of the width are equal and the 2 sides of the length are equal.

Therefore the equation for the perimeter of a rectangle can be written as:

p

=

2

⋅

l

⋅

where  

p

is the perimeter,  

l

is the length and  

w

The distance between A and B is 7 squares to the right and 3 squares down

Answer:

The yellow trapezoid, blue rectangle, and whatever that purple thing is are zingoes

Step-by-step explanation:

As far as I can tell, all the correct examples are

1) Symmetrical

2) Have a line splitting them symmetrically and does not go above or below the shape (Does that make sense?)

The wrong examples don't have any of the characteristics told above. For example, the square would be wrong because it doesn't even have a line

(P.S- This isn't my picture, just found it on the web. Shout out to whoever owns this)

Answer:

Step-by-step explanation:

Divide the numbers first because that's the easy part and we've been dividing since like 5th grade.

1.6/.2 = 8. Now for the exponents.

When you divide like bases, you subtract the exponents. Our bases are both 10's, so they are like. Subtracting the exponents gives us 10³. So the answer is 8 × 10³, choice B.

Answer:

210

Step-by-step explanation:

Lets use BEDMAS (Brackets, Exponents, Division, Multiplication, Addition, Subtraction)

45 ÷ 2 = 22.5

22.5 × 8 = 180

180 - 12 = 168

168 + 42 = 210

Answer:

Each friend raised $ 182.50.

Step-by-step explanation:

Given that four friends raised a total of $ 730 for a local charity, and each friend raised the same amount of money, for model the total amount that the friends raised the following calculation must be performed:

730/4 = X

182.5 = X

Therefore, each friend raised $ 182.50.

Answer:

$77429.824

Step-by-step explanation:

Let the total college cost for one year = x

43% of x was paid with scholarship fee

Percentage left = 100% - 43% = 57%

57% is equivalent to 11,033.75

57/100x= 11,033.75

0.57x = 11033.75

x = 11033.75 / 0.57

x =19357.456 ; this is Jacinta's college fee for a year ;

Hence

College fee for 4 years :

19357.456 * 4 = $77429.824

Answer: 26 cards

Step-by-step explanation:

Suppose there are x cards initially

Min gave half to bill i.e. 0.5x

Bill gives one-third of those cards to Sam i.e. [tex]\frac{1}{3}\times 0.5x[/tex]

Sam gave 2 cards back to min and kept 6 i.e. Sam gets 8 cards from Bill

[tex]\Rightarrow 8=\dfrac{1}{3}\times 0.5x\\\\\Rightarrow 0.5x=24\\\Rightarrow x=48[/tex]

So, min has 0.5x+2 cards i.e.

[tex]\Rightarrow 0.5\times 48+2\\\Rightarrow 26\ \text{cards}[/tex]

Answer:

Doña Juana tiene 83,782 hectáreas cultivadas en total.

Step-by-step explanation:

Dado que Doña Juana tiene cultivadas 80 hectómetros cuadrados de naranjas, 300 decámetros cuadrados de mandarinas, 700000 decímetros cuadrados de limones y 8200000 centímetros cuadrados de toronjas, para determinar cuántas hectáreas en total tiene cultivadas se deben realizar los siguientes cálculos:

1 Hm2 = 1 hectárea x 80 = 80 hectáreas

1 Dam2 = 0.01 hectárea x 300 = 3 hectáreas

1 Dm2 = 0.000001 hectárea x 700000 = 0.7 hectáreas

1 Cm2 = 0.00000001 hectárea x 8200000 = 0.082 hectáreas

80 + 3 + 0.7 + 0.082 = X

83,782 = X

Por lo tanto, Doña Juana tiene 83,782 hectáreas cultivadas en total.

1011₂ + 10111₂

= (1000₂ + 10₂ + 1₂) + (10000₂ + 100₂ + 10₂ + 1₂)

= 10000₂ + 1000₂ + 100₂ + 2 (10₂) + 2 (1₂)

= 10000₂ + 1000₂ + 100₂ + 2 (10₂) + 10₂

= 10000₂ + 1000₂ + 100₂ + 100₂ + 10₂

= 10000₂ + 1000₂ + 2 (100₂) + 10₂

= 10000₂ + 1000₂ + 1000₂ + 10₂

= 10000₂ + 2 (1000₂) + 10₂

= 10000₂ + 10000₂ + 10₂

= 2 (10000₂) + 10₂

= 100000₂ + 10₂

= 100010₂

Answer:

step-by-step explanation: 1cm is equal to 10mm

The volume of a cuboid is length ×breadth×height

We start by converting 60 mm into cm which will be 6cm

Solution :

462cm3=11cm×6cm

462cm3/66=66cm/66

The final answer will be 7cm

Therefore the height is 7cm

Answer:

11 in

Step-by-step explanation:

The area of a square is given by

A = s^2 where s is the side length

121 = s^2

Taking the square root of each side

sqrt(121) = sqrt(s^2)

11= s

Answer:

The side of square is 11 m.

Step-by-step explanation:

To calculate the side of square .

Here, given area of square which is 121 inches².

Using Formula :-

where, side is the length of side of square.

Solution :-

Area of square = ( side )²

121 inches² = side²

Taking square root of both side

√121 inches² = √side²

11 inche = side

Hence, The side of square is 11 inche.

Answer:

$480

Step-by-step explanation:

multiply the normal price $600 by 20 then divide it by one hundred

the discount is $120

the sales price is subracting the discount of $120 from the original price of $600 then get $480 as the sales price.

Answer:

Step-by-step explanation:

Method 1:  Subtract 20% from 100%, obtaining 80%, and then multiply the regular price ($600) by the decimal equivalent 0.80.  We get $480 as the sale price.

Method 2: Calculate the amount of the discount by multiplying $600 by 0.20, obtaining $120.  Then subtract this discount from the regular price, $600, obtaining $480.
