Area de la base es un hexagono: Nota: asumiendo que 39 cm son el lado de un hexagono. Menuda pizza.
A = 3*sqrt(3)/2*a^2 = 3*sqrt(3)/2*39^2 = 3951.67391746839972 cm^2
Hay dos base y tapa, doble:
7903.34783493679944 cm^2
Luego los lados verticales:
6 * 39 * 4.7 = 1099.8 cm^2
TOtal = 9003.14783 = 9003.147 cm^2 = 9003.15 cm^2
The one that makes the most sense is C
For this case, what we are going to do first is to assume that all the exams are worth the same percentage of the final grade.
We have then that Lisa's average grade point equation is:
Where,
x: minimum note that lisa must obtain in the last exam.
Clearing x we have:
Answer:
the lowest grade she can get on her last test is:
x = 94
Answer:
x+ x+1 + x+2 = 30
3x+3 =30
Step-by-step explanation:
Let x be the smallest integer
x+1 be the next smallest
x+2 be the third
x+ x+1 + x+2 = 30
Combine like terms
3x+3 =30
Answer:
-7< x < 6
Step-by-step explanation:
|4x + 2| < 26
The absolute value has a positive and a negative. Remember to flip the inequality when taking the negative
4x+2 < 26 and 4x+2 > -26
Subtract 2 from each side
4x+2-2 < 26 -2 and 4x+2 > -26-2
4x < 24 and 4x > -28
Divide by 4
4x/4 < 24 4x/4 >-28/4
x <6 and x> -7
-7< x < 6
