A rectangular swimming pool is 19 meters long, 11 1/2 meters wide, and 1 1/2 meters deep. What is its volume?

2 answers:

8 0

Volume = length x breadth (width) x height

19m long --> length
11 1/2m wide --> width (aka breadth)
1 1/2m deep --> height

Volume = 19m x 11 1/2m x 1 1/2m = 327.75m²

Answer:

$327\frac{3}{4}$

Step-by-step explanation:

→ State the volume of a rectangular prism

Length × Width × Height

→ Substitute in the numbers

$19*11\frac{1}{2} *1\frac{1}{2}$

→ Convert to improper fractions

$\frac{19}{1} *\frac{23}{2} *\frac{3}{2}$

→ Multiply

$\frac{1311}{4}$

→ Convert to mixed fraction

$327\frac{3}{4}$

ycow [4]

Answer: B. 350.

Step-by-step explanation:

Given: Total number of fluorescent colors = 7

Total number of pastel colors = 5

Since , he want three fluorescent colors and two pastel colors.

Number of ways to select r things out of n things = $^nC_r=\dfrac{n!}{r!(n-r)!}$

Number of ways to choose colors = $^7C_3\times\ ^5C_2$

$=\dfrac{7!}{3!4!}\times\dfrac{5!}{2!3!}\\\\=\dfrac{7\times6\times5\times4!}{3\times2\times1\times4!}\times\dfrac{5\times4\times3!}{2\times3!}\\\\=350$

Hence, the correct option is B. 350.

laiz [17]

You would do

(1.1)(80,000,000)=88,000,000

That is the total cars for year two. To find the increase you would do

(1.1)(88,000,000)=96,800,000

Then you would subtract year 2 from year three

96,800,000-88,000,00=8,800,000

That gives you ur answer.

6j-k=23<br>3k+6j=11<br>Solve j and k using the elimination method on the simultaneous equations

frez [133]

Answer:

Step-by-step explanation:

6j - k = 23

6j + 3k = 11.....multiply by -1

---------------

6j - k = 23

-6j - 3k = -11 (result of multiplying by -1)

---------------

-4k = 12

k = -12/4

k = - 3 <=====

6j - k = 23

6j - (-3) = 23

6j + 3 = 23

6j = 23 - 3

6j = 20

j = 20/6

j = 10/3 <===

solution is : j = 10/3 and k = -3
