We are given that the initial depth of snow is 10 cm

while the rate of melting is 1/3 cm per hour. So the melted ice after 3 hours

is:

melted = (1/3 cm/hr) * 3 hours = 1 cm

Hence the depth left is:

depth = 10 cm – 1 cm = 9 cm

Answer:

9 cm

Slope of -8,4 and 3,-4

nata0808 [166]

For this case we have that by definition, the slope of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

Where:

$(x_ {1}, y_ {1})$ and $(x_ {2}, y_ {2})$ are two points through which the line passes

According to the statement we have:

$(x_ {1}, y_ {1}): (- 8,4)\\(x_ {2}, y_ {2}) :( 3, -4)$

Substituting we have:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-4-4} {3 - (- 8)} = \frac {-8} {3 + 8} = \frac {-8} {11} = - \frac {8} {11}$

Thus, the slope of the line is:

$m = - \frac {8} {11}$

Answer:

$m = - \frac {8} {11}$

Solve for x. 5/6 x = 10/3 x = 4/3 x = 2 x = 25/9 x = 4

SashulF [63]

Answer: LAST OPTION.

Step-by-step explanation:

In order to solve for the variable "x" from the expression $\frac{5}{6}x=\frac{10}{3}$ , you need to follow these steps:

1) You need to multiply both sides of the equation by 3:

$3(\frac{5}{6}x)=(\frac{10}{3})(3)\\\\\frac{15}{6}x=10$

2) You need to multiply both sides of the equation by 6:

$(6)(\frac{15}{6}x)=(10)(6)\\\\15x=60$

3) Finally, you can divide both sides of the equation by 15:

$\frac{15x}{15}=\frac{60}{15}\\\\x=4$
