Answer:
33.49 mm³
Step-by-step explanation:
The formula of volume of sphere

The volume of the sphere



= 33.49 mm³ (rounded to the nearest hundredth)
Answer:
96 square inches
Step-by-step explanation:
The scale is 2 inches : 3 feet
Thus for 18 feet in Serika's real house, the model is 18 * (2"/3') = 12 inches
For 12 feet in Serika's real house, the model is 12 * (2"/3') = 8 inches
Area of carpeting needed in Serika's dollhouse = 12" * 8" = 96 square inches
Answer:
91
Step-by-step explanation:
12∣∣−x+3∣∣−5
Let x = 11
12∣∣−11+3∣∣−5
Do the absolute value first
12∣∣-8∣∣−5
Taking the absolute value, which means making it positive
12* 8 -5
Multiply and divide
96 -5
91
The best approximation for the solution to this system of equations is (-2.2,-3)
Option C is correct.
Step-by-step explanation:
Solving the system of equations to get the exact value of x:

Let

Putting value of y from eq(1) into eq(2)



So, Value of x is -2.2
The best approximation for the solution to this system of equations is:
x=-2.2 and y = -3
(-2.2,-3)
Option C is correct.
