Answer:

\mathsf {SA = 112 in.^{2} }

Step-by-step explanation:

\textsf {Formula used :}\\\implies \textsf {SA = 2(length * width + width * height + length * height) }

\textsf {Given :}\\\textsf {Length = 5 in.}\\\textsf {Width = 4 in.}\\\textsf {Height = 4 in.}

\textsf {Solving :}

\implies \mathsf {SA = 2 (5 * 4 + 4 * 4 + 5 * 4)}

\implies \mathsf {SA = 2 (20 + 16 + 20)}

\implies \mathsf {SA = 2 (56)}

\implies \mathsf {SA = 112 in.^{2} }

Nicole is playing a video game where each round lasts 3/44 of an hour. She has scheduled 3 3/4 hours to play the game. How many
Marrrta [24]
Let's not think about the problem, let's think about the fractions and dividing. We're are trying to find how many sets of 3/44 are in 3 3/4. We need to divide. Using keep change and flip, we can divide successfully.
Let's make sure the first fraction is improper.
15/4÷3/44=?
Keep, Change, and Flip.
15/4×44/3
660/12
Let's simplify.
55.
So Nicole can play 55 rounds.

Jaimie said that one million less than 26 470 035 000 was 26 370 035 000. Kristin said that 0.008 was less than one thousandth.
Novosadov [1.4K]
Jaimie was wrong, because 26,470,035,000-one million(1,000,000) = 2.646904e10
And Kristin was right because 0.008<1,000 is a true statement.

A shop sells a party hat at x dollars and a mask at y dollars. On a particular morning, 3 hats and 4 masks were sold for $27. In
Aleks [24]

Answer:

Cost of each hat: $5

Cost of each mask: $3

Step-by-step explanation:

Let be "x" the cost in dollars of a party hat and "y" the cost in dollars of a mask.

Set up a System of equations using the information given in the exercise:

\left \{ {{3x+4y=27} \atop {3x+6y=33}} \right.

You can use the Elimination Method to solve this System of equations:

1. You can multiply the first equation by -1.

2. Then you must add the equations.

3. Solve for "y".

Then:

\left \{ {{-3x-4y=-27} \atop {3x+6y=33}} \right.\\.....................\\2y=6\\\\y=\frac{6}{2}\\\\y=3

4. Now you can substitute the value of "y" into any original equation.

5. Finally, solve for "x" in order to find its value.

Then:

 3x+4(3)=27\\\\3x=27-12\\\\x=\frac{15}{3}\\\\x=5
