Option C) 120cm² is the correct answer.

Hence, the lateral surface area of the rectangular prism in 120cm².

This question is incomplete, the complete question is;

Find the lateral surface area of the rectangular prism in centimeters.

L=4, W=3, H=9

A) 96 cm2 b) 108 cm2 c) 126 cm2 d) 142 cm2.

<h3>Rectangular prism</h3>

A rectangular prism or Cuboid is simply a three dimensional solid shape with six faces that are rectangles.

The lateral surface area of the rectangular prism is the perimeter of the base multiply by the height of the prism. It is expressed as:

$LSA = 2 ( l + w ) h$

To determine the lateral surface area of the rectangular prism, we substitute our given values into the above expression.

$L.S.A = 2(l+w)h\\\\L.S.A = 2( 4cm + 3cm )9cm\\\\L.S.A = 2( 7cm)9cm\\\\L.S.A = 126cm^2$

Option C) 120cm² is the correct answer.

Hence, the lateral surface area of the rectangular prism in 120cm².

Sean received both the 5th highest and the 5th lowest mark in the class. How many students are there in the class?.

kolezko [41]

If we read the complete exercise, we can understand that the correct answer is 9 students.

This is a math related exercise.

If we take into consideration that Sean is the 5th highest in the class, it means that there are four more people before him.

However, he is also the 5th lowest mark in the class, so it means that there are four more people below him.

If we also count Sean, there are:

9 students in the class.

Roman55 [17]

Answer:

"if all the money spent on war was spent on ending poverty and finding environmental answers, what a wonderful place this earth would be!"

Explanation:

"The Girl Who Silenced the World for Five Minutes" was a speech delivered in 1992 by a twelve-year-old girl named Severn Cullis Suzuki. The speech was addressed in the U.N. assembly in Brazil.

She spoke about the threat being posed by humans on the environment. She called the whole earth a family of 5 billion people with some 30 million species.

<u>In her speech, she opines about how can the government use the monetary system to strengthen and make the earth a beautiful place to live in. She opined that the money that is spent on war instead should be used to end poverty and build the environment.</u>

The excerpt that suggests her opine is stated above in the answer section.

The population of two different villages are modeled by the equations shown below. The population (in thousands) is represented

PilotLPTM [1.2K]

Answer:

1990 and 2010

$y_l_w(15)=315\hspace{3}thousands\\y_l_c(15)=315\hspace{3}thousands\\y_l_w(35)=715\hspace{3}thousands\\y_l_c(35)=715\hspace{3}thousands$

Explanation:

Let:

$y_l_w=Population\hspace{3}of\hspace{3}Lewiston\\y_l_c=Population\hspace{3}of\hspace{3}Lockport$

We need to know, in what year(s) the villages had the same population, mathematically this is:

$y_l_w=y_l_c$

So:

$x^2-30x+540=20x+15\\\\Subtract\hspace{3}20x\hspace{3}from\hspace{3}both\hspace{3}sides\\\\x^2-50x+540=15\\\\Subtract\hspace{3}15\hspace{3}from\hspace{3}both\hspace{3}sides\\\\x^2-50x+525=0$

Solving for x:

Factoring

$(x-15)(x-35)=0$

Hence:

$x=15\\\\or\\\\x=35$

Therefore the year(s) which the village had the same population are:

$1975+15=1990\\\\and\\\\1975+35=2010$

In order to find the population of both cities during the year(s) of equal population, just evalue the equations at x=15 and x=35:

$y_l_w(15)=315\hspace{3}thousands\\y_l_c(15)=315\hspace{3}thousands\\y_l_w(35)=715\hspace{3}thousands\\y_l_c(35)=715\hspace{3}thousands$

A new car is purchased for 19000 dollars. The value of the car depreciates at 11. 25% per year. What will the value of the car b

VikaD [51]

Answer:

3573.64

Explanation:

y=ab^x

a=starting value = 19000

r=rate = 11.25%=0.1125

Exponential Decay:

b=1-r=1-0.1125=0.8875

Write Exponential Function:

y=19000(0.8875)^x

Plug in time for x:

y=19000(0.8875)^14

y= 3573.6388855

Evaluate :

y≈3573.64
