Front

What is the mass of Jupiter in scientific notation?

Back

5.69 X 10^{28} kg

Front

What is the mass of Mars in scientific notation?

Back

6.4 X 10^{21} kg

Front

How do you calculate how many times more mass Jupiter has than Mars?

Back

Divide the mass of Jupiter by the mass of Mars: \( \frac{5.69 \times 10^{28}}{6.4 \times 10^{21}} \approx 8.9 \times 10^{6} \)

Front

What is the formula for the surface area of a rectangle?

Back

Front

If the surface area of a figure is 800 cm², what could be the dimensions if it is a rectangle?

Back

Possible dimensions could be Length = 20 cm and Width = 40 cm.

Front

What is the formula for the volume of a rectangular prism?

Back

Volume = Length × Width × Height

Front

If the volume of a rectangular prism is 179.59 cm³, what could be the dimensions if Height = 1 cm?

Front

How do you write an equation for a word problem involving students in cars and buses?

Back

Let x be the number of students in each bus. The equation is: 4 + 9x = 472.

Front

What is the perimeter formula for a rectangle?

Back

Perimeter = 2(Length + Width) or P = 2L + 2W.

Front

If the perimeter of a rectangular garden is 44 cm and Length is 12 cm more than Width, how do you express this?

Back

Let Width = w, then Length = w + 12. The equation is: 2(w + (w + 12)) = 44.
