Convert the following measurements. Round your answers to two decimal places. a. 14,974 pounds to tons b. 8,047 ounces to pounds

Vikki [24]

For this case we have to know the following conversions:
$1 ton = 2204.62 pounds

1 oz = 0.0625 pounds$
Now we apply the conversions:

14,974 pounds to tons:
$(14974) * (1 / 2204.62) = 6.79 tons
$

8,047 ounces to pounds:
$(8047) * (0.0625) = 502.94 pounds
$

64 ounces to pounds:
$(64) * (0.0625) = 4 pounds
$

27 ton to pounds:
$(27) * (2204.62) = 59524.74 pounds$

A line with a slope of -2 passes through the points (0,d) and (-8,9). What is the value of d?

Verizon [17]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have m = -2 and the points (0, d) and (-8, 9). Substitute:

$\dfrac{9-d}{-8-0}=-2\\\\\dfrac{9-d}{-8}=-2\qquad\text{multiply both sides by (-8)}\\\\9-d=16\qquad\text{subtract 9 from both sides}\\\\-d=7\qquad\text{change the signs}\\\\\boxed{d=-7}$
