1/8=2/16 or 4/32 or 3/24
As long as you multiply or divide by the same number to both the numerator and denominator you will get a proportional ratio
Answer:
15.71 metros cúbicos de aceite transportará el depósito del camión.
Step-by-step explanation:
Un camión transporta aceite de oliva en un deposito con forma de cilindro de 1 m de radio y 5 m de altura.
Para calcular la cantidad de aceite que transportará se debe calcular el volumen del depósito, siendo con forma de cilindro. El volumen de dicha figura es calculada como V=π*r²*h, donde r es el radio y h es la altura.
En este caso, el volumen del depósito cilíndrico es:
V=π*( 1 m)²*5 m
Resolviendo:
V=15,71 m³
<u><em>15.71 metros cúbicos de aceite transportará el depósito del camión.</em></u>
All you have to do is substitute the y value from the 1st equation into the second equation and solve...
a) y= 2-x
5x + 4y = 5
Substitute (2-x) into the second equation anywhere there is a y...
5x + 4y = 5
5x + 4(2-x) = 5
Now solve
5x + 8 - 4x = 5
5x - 4x + 8 = 5
x + 8 = 5
x = -3
Now that you have a solution for x, substitute -3 into either of the original equations anywhere there is an x then solve for y...
y = 2 - x
y = 2 - (-3)
y = 2+3 = 5
You solved for x and got -3 and solved for y and got 5, so your solution set is
(-3, 5).
Now check it by substituting both numbers into one of the original equations and you should have a true statement if it is correct...
y = 2 - x
5 = 2 - (-3)
5 = 2+3
5 = 5
True statement... it checks!
note* during the check, if the equation would have worked out to something like 2 = 5, then that is a false statement therefore the solution set would be wrong and you'd have to go back and find the mistake.
Answer:
B. 1.2 x 10^-1
Step-by-step explanation:
3.6 x 10^7 = 36,000,000
3 x 10^8 = 300,000,000
36,000,000 ÷ 300,000,000 = 0.12
= 1.2 x 10^-1
Geometric, hope this help
