Answer:
A distância do porto A ao porto D pode ser calculada com auxílio do teorema de Pitágoras, pois o triângulo retângulo que se pode obter traçando-se uma paralela à trajetória do porto B ao porto C passando pelo ponto A tem as seguintes medidas
catetos 30 e 40 sendo que a hipotenusa é a distãncia de A até D:
Step-by-step explanation:
resolvendo:
Logo, pelo caminho percorrido completou 70+30+110= 210 milhas
Teria economizado, então, 210 - 50 = 160 milhas
Answer:
Adrian needs to pay $5 for all the fruit.
Step-by-step explanation:
Consider the provided information.
Grapes cost $2.35 per pound, oranges cost $0.99 per pound, and apples cost $1.65 per pound.
In order to find how much Adrian needs to pay we need to add $2.35, $0.99 and $1.65.
Now round $4.99 to the nearest whole number.
Hence, Adrian needs to pay $5 for all the fruit.
Answer:
C. Use properties of equality to get the variable on one side of the equation and constant terms on the other.
Step-by-step explanation:
In solving an equation, It is true that properties of equality should be used by putting the variable on one side and the constant on the other side.
Now let use an example to drive this;
Given:
2x - 9 = x + 8
This is an equation, and what we have on both sides should be equal.
Collect like terms;
2x - x = 8 + 9
x = 17
So the solution is 17.
This is the best way to solve an equation.
