Answer:

35?

Step-by-step explanation:

3x+2y=70

Geometric figure: Straight Line

Slope = -3.000/2.000 = -1.500

x-intercept = 70/3 = 23.33333

y-intercept = 70/2 = 35

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 35/1 so this line "cuts" the y axis at y=35.00000

y-intercept = 70/2 = 35

Calculate the X-Intercept :

When y = 0 the value of x is 70/3 Our line therefore "cuts" the x axis at x=23.33333

x-intercept = 70/3 = 23.33333

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 35.000 and for x=2.000, the value of y is 32.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 32.000 - 35.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -3.000/2.000 = -1.500

Geometric figure: Straight Line

Slope = -3.000/2.000 = -1.500

x-intercept = 70/3 = 23.33333

y-intercept = 70/2 = 35

Larissa argued that since log2(2) = 1 and log2(4) = 2, then it must be true that log2(3) = 1.5. Is she correct?

mestny [16]

Answer:

$2^{1.5} = 2.8284$ . This means that Larissa is not correct.

Step-by-step explanation:

To solve logarithms, we have to consider the following:

$\log_{a}(b)$ = c means that $a^{c} = b$ .

So, for example:

$log_{2}(2) = 1$ because $2^{1} = 2$ .

$log_{2}(4) = 2$ because $2^{2} = 4$ .

If $2^{1.5} = 3$ , then Larissa is correct. However, $2^{1.5} = 2.8284$ . This means that Larissa is not correct.

La finca de Federico tiene tiene un área de 576 m2, En ella ha sembrado naranja y café, 3/8 de la finca están sembrados de naran

Vanyuwa [196]

Answer:

El área de la finca que está sembrada por café es 360 m².

Step-by-step explanation:

La finca de Federico tiene tiene un área de 576 m². $\frac{3}{8}$ de la finca están sembrados de naranjas. Entonces, el área de la finca que está sembrada por naranjas se calcula mediante:

576 m²* $\frac{3}{8}$ = 216 m²

Sabiendo que el resto de la finca esta sembrada de café, esta área se calcula mediante la diferencia del área total de la finca y el área sembrada por naranjas:

576 m² - 216 m²= 360 m²

El área de la finca que está sembrada por café es 360 m².
