Mr. Jansen is building an ice rink in his backyard that will measure 8.4 meters by 22 meters. What is the area of the rink?

Answers

Answer 1
The area of Mr.Jansen ice rink in the backyard is 184.8
Answer 2

The area of the rink is 184.8 m²

Further Explanation

From the problem above we know the measurement of the ice rink is

22 x 8.4 m

to calculate the area = length x width

                                   = 22 x 8.4

Here is how to solve the decimal multiplication, we are going to multiply them as a whole number. The different is the placement of the decimal point in the answer. Using the standard algorithm method, the calculation would be:

 22             ⇒ whole number (no decimal place)

 8.4  x        ⇒ 1 decimal place

 88          

176  +

184.8           ⇒ 1 decimal place

The first factor 22 doesn't decimal place

The second factor 8.4 has one decimal place

The result will has one decimal place (0+1=1)

Which fraction is bigger 5/6 or 8/9?

Answers

5/6 = 5 ÷ 6 = 0.8333

8/9 = 8 ÷ 9 = 0.8888

so 8/9 is bigger.

hope this helped, God bless!
8/9 would be bigger.

This would be because, the number on the right side of the dash, is how many times 1 is split up, and the number on the left is the amount of split up chunks you would take.

In this case, 5/6, you would have 1 split into 6 chunks, and taking 5 out of 6 of them. 8/9 would be 1 split into 9 chunks, and taking 8 out of 9 of them.

Since there are more parts in 8/9 and you're taking almost all of them, it would be bigger then 5/6.

So therefore 8/9 is bigger.

And help on this one too.

To find the amount of syrup, multiply the amount of syrup per gallon by the number of gallons of soda. In this case, this would be 2 1/5 cups and 4 gallons.

2 1/5 x 4

(Changing the mixed number 2 1/5 to an improper fraction!)

11/5 x 4/1 = 44/5

Express as decimal numerals one and three hundred twenty four thousandths

Answers

The answer would be 1.324

One and three hundred twenty four thousandths expressed as a decimal numeral is [tex]1.324[/tex].

To express "one and three hundred twenty four thousandths" as a decimal numeral, follow these steps:

Understand the components:

• "One" represents the whole number part.

• "Three hundred twenty four thousandths" represents the fractional part.

Express the whole number part as a decimal:

• The whole number "one" is simply [tex]1[/tex].

Convert the fractional part to a decimal:

• "Three hundred twenty four thousandths" means 324 out of 1000, which can be written as the fraction [tex]\frac{324}{1000}[/tex].

• To convert [tex]\frac{324}{1000}[/tex] to a decimal, divide 324 by 1000. This gives us [tex]0.324[/tex].

Combine the whole number and the fractional part:

• Add the whole number part [tex]1[/tex] to the fractional part [tex]0.324[/tex]. This results in [tex]1 + 0.324 = 1.324[/tex].

How do you turn 8/10 as a percent

Answers

Since the percentage is 8/10, we can take it and mutiply it by 10 (8 and 10) to get 80/100. The percentage is 80%.
Hello! To turn 8/10 as a percent, just write out and solve a proportion. It would be set up like this: 8/10 = x/100. Percent is parts of 100 and you want to know the percent that 8/10 would be, so you put the “x” up top. Cross multiply the values. 8 * 100 is 800 and 10 * x = 10. You would get 800 = 10x. Now, divide each side by 10 to isolate the “x”. 800/10 is 80. x = &”. There. 8/10 as a percent is 80%.

An ostrich egg has about the same volume as a sphere with a diameter of 5 inches. If the eggshell is 1/12 inch thick, find the volume of just the shell, NOT including the interior of the egg. Round to the nearest tenth

Answers

volume of the shell is 3.1 cubic inches

The equation below shows the total volume (V),in cubic units, of 2 identical boxes with each side equal to s units:

V = 2s3

If s = 3.5 units, what is the value of V?

A: 21.0 cubic units
B: 24.5 cubic units
C: 36.75 cubic units
D: 85.75 cubic units

Answers

A. 21.0 cubic units
2 × 3.5 × 3

when [tex]$s = 3.5$[/tex] units, the total volume V of the two identical boxes is  85.75 cubic units. So option (d) is correct.

To find the total volume V of two identical boxes, we use the formula $V [tex]= 2s^3$[/tex], where s represents the length of a side of the box.

Given that s = 3.5 units, we substitute this value into the equation:

[tex]$$V = 2 \times (3.5)^3$$[/tex]

First, calculate the cube of 3.5:

[tex]$$(3.5)^3 = 3.5 \times 3.5 \times 3.5 = 42.875$$[/tex]

Now, multiply the result by 2 to find V:

[tex]$$V = 2 \times 42.875 = 85.75$$[/tex]

So, when [tex]$s = 3.5$[/tex] units, the total volume V of the two identical boxes is  85.75 cubic units.

The answer is:  "25 feet" 
____________________________________________
Explanation:
___________________________________________

Perimeter  = 2*(length) + 2*(width); 

or;  "P = 2L + 2w " ;.
____________________________________________
In this case:  

"P = (2L + 2w) − 2 ⅚ " ; solve for "P" ; all units are in "feet (ft)" ;
____________________________________________________
From the diagram; we are given:
____________________________________________________
  L = 12 ¼ ;
 
  w = 10 ; 
____________________________________________________

        →   " P = { [2* (12 ¼) ] + [2* 10] }  − 2 ⅚  " ;  Solve for "P" ;
__________________________________________________________
Note:  Rewrite "12 ¼" ;  AND:  "2 ⅚" as "improper fractions" :
_________________________________________________________
→ " 12 ¼ = [ (4*12) + 1 ] / 4 = [tex] \frac{48+1}{4} [/tex] = [tex] \frac{49}{4}[/tex] "  ;

→ " 2 ⅚  = [ (6*2) + 5 ] / 6 = [tex] \frac{12+5}{6} [/tex] = [tex] \frac{17}{6}[/tex] "   ;
_________________________________________________________ 
Rewrite our equation: 

→   " P = { [2* (12 ¼) ] + [2* 10] }  − 2 ⅚  " ;;

substituting the "mixed numbers" with "improper fractions" ;
→   " P = { [2* ([tex] \frac{49}{4}[/tex]) + [2* 10] }  − [tex] \frac{17}{6}[/tex] " ;
________________________________________________________
→ Note: " 2*[tex] \frac{49}{4}[/tex] ;

                   = [tex] \frac{2}{1} [/tex] *[tex] \frac{49}{4}[/tex] " ;

The "2" in the "  [tex] \frac{2}{1} [/tex]  " 
      cancels to "1" ; and the "4" in the " [tex] \frac{49}{4}[/tex] " 
     cancels to "2" ;  {Since:  "(4÷2=2)" ; and since:  "(2÷2=1)" ;

    →  and we have:   " 2*[tex] \frac{49}{4}[/tex] = "  [tex] \frac{49}{2} [/tex]   " .
___________________________________________________
Note:  {2*10] = 20 .
___________________________________________________
So; we can rewrite our equation as follows:
___________________________________________________
→ " P =  [tex] \frac{49}{2}[/tex]  +  20 − [tex] \frac{17}{6}[/tex] " ;  
___________________________________________________
Now, multiply the entire equation (both sides) by "6" ;
                                        to get rid of the fractions;
____________________________________________________
→ 6*{P =  [tex] \frac{49}{2}[/tex]  +  20 − [tex] \frac{17}{6}[/tex] } ;
____________________________________________________
to get:
____________________________________________________
  → 6P = ([tex] \frac{6}{2}[/tex] *49)  +  20  −  (6*[tex] \frac{17}{6}[/tex]) ;

  → 6P = (3 * 49) + 20  −  ([tex] \frac{6}{6} [/tex] * 17) ;

             →  6P = ( 3 * 49) + 20  −  (1 * 17)  ;

             →  6P = ( 3 * 49) + 20  −  (1 * 17)  ;

             →  6P =  (147) + 20 − 17 ;

             →  6P = 147 + 20 − 17 ;

             →  6P  = (147 + 20) − 17 ;
 
             →  6P = 167 − 17 ;

             →  6P = 150 ;
__________________________
Now, divide EACH SIDE of the equation by "6" ; to isolate "P" on one side of the equation; and to solve for "P" (which is our answer, in units of "feet" (ft). ;
__________________________
             → 6P / 6  =  150 / 6 ;

to get:  →   P = 25 .
_____________________________________________
The answer is:  "25 feet" .
