Answer:
-74
Step-by-step explanation:
Answer:
Since this is a right triangle with one angle and hypotenuse given and opposite side unknown, we can use the definition of sine to find the unknown side.
sin 17 = x/hypotenuse = x/19
x = 19sin17 = 5.6
Answer:
79
Step-by-step explanation:
78

78^2 = 6084.
We observe that 78^2 < 6203.
79^2 = 6241.
We observe that 79^2 > 6203.
Hence the number to be added to 6203 is 6241 - 6203 = 38.
6203 + 38 = 3241
= 79 * 79
= 79.
Therefore 38 should be added to 6203 to obtain a perfect square.
Answer:
290 gramas
Step-by-step explanation:
Podemos interpretar a questão acima matematicamente como:
3 pacotes = 870 gramas
1 pacote = x
Multiplicação cruzada
3x = 1 × 870 gramas
Divida os dois lados por 3
3x / 3 = 1 × 870 gramas / 3
x = 290 gramas
Portanto, cada pacote conteria 290 gramas de carne moída
