Answer:
561
Step-by-step explanation:
assuming the ^ means to the power of, 7*7 is 49 and 8*8*8 is 512
C = -5/3 = -1 2/3
Write down the equation and solve for c
-3 - 3/4(c-4) = 5/4
Distribute the 3/4
-3 -(3/4)c + 3 = 5/4
Perform the addition of -3 and 3
-(3/4)c = 5/4
Divide both sides by -(3/4)
c = 5/4 / (-3/4) = 5/4 * (-4/3) = -20/12 = -5/3
So the value of c is -5/3. Let's verify it.
-3 - 3/4(-5/3 - 4) = x
Distribute the -3/4
-3 - (3/4)(-5/3) + (3/4)4 = x
-3 +15/12 + 3 = x
Combine terms
15/12 = x
Simplify
5/4 = x
The snowman is made of 3 spheres (balls) of snow. The diameters, from top to bottom, are 12, 16, 18 inches
Therefore, the radii of the 3 spheres are, respectively, 6, 8, and 9 inches.
The volume of a sphere of radius, r, is given by the formula: V = 4/3 π r3
So, the total volume of snow is the sum of the 3 volumes: V = 4/3 π (63 + 83 + 93)
= 4/3 π (1,457)
=6,099.97
Your answer would be D. 6,099.97
I hope this helps!
Answer:
El 40% de los estudiantes reprobaron la asignatura.
Step-by-step explanation:
Dado que sabes el número total de estudiantes y cuántos aprobaron la asignatura, puedes restar el número de estudiantes que aprobaron del total de estudiantes para encontrar los estudiantes que reprobaron la asignatura:
50-30=20
Ahora puedes calcular el porcentaje dividiendo el número de estudiantes que reprobaron entre el total de estudiantes y multiplicando el resultado por 100:
20/50*100=40%
De acuerdo a esto, la respuesta es que el 40% de los estudiantes reprobaron la asignatura.
