Answer:
inverse variation
Step-by-step explanation:
F is inversly proportional to r
Answer: A, B, D
A, B, and D are equations because an equation has an equal sign that connects two expressions together (i.e., equations have equal signs). In this case, only A, B, and D have equal signs.

Espero que la info. ayude
El símbolo de grado no se usa para informar la temperatura usando la escala Kelvin, sino que se indican como Kelvin. El agua hierve a 100 grados Celsius o 212 grados Fahrenheit, o 373,15 Kelvins. El agua se congela a 0 grados Celsius o 32 grados Fahrenheit, o 273,15 Kelvins. El cero absoluto es 0 Kelvin.
Answer:
Decimal Form:
4.99873244
Step-by-step explanation:
geometry is the worst. but i have a way to remember how to find the area. (Apple Pies are too --> A=πr^2 --> area = pie×radius^squared) so basically you sub in 78.5 in for area and then you solve for r.
Hope i helped kinda lol
Answer: 22 small snow cones and 34 large snow cones were sold.
Step-by-step explanation:
Let x represent the number of small snow cones that were sold.
Let y represent the number of large snow cones that were sold.
Selena's snow cone stand sells small snow cones for $2 and large snow cones for $3.50. One summer day, she sold $163 worth of snow cones. This means that
2x + 3.5y = 163 - - - - - - - - - - 1
If the number of large snow cones sold was 12 more than the number of smalls snow cones, it means that
y = x + 12
Substituting y = x + 12 into equation 1, it becomes
2x + 3.5(x + 12) = 163
2x + 3.5x + 42 = 163
5.5x = 163 - 42
5.5x = 121
x = 121/.5 = 22
y = x + 12 = 22 + 12
y = 34
