A truck is carrying 3 tons of cement and 150 pounds of bricks. How many pounds does the truck's load weigh in total

vodomira [7]

Answer: $6,150 \text{ pounds}$

Step-by-step explanation:

Given: The weight of cement = 3 tons

The weight of bricks = 150 pounds

We know that $\text{1 ton = 2,000 pounds}$

Therefore, $\text{3 tons}=3\times2,000=6,000$

Now, the total weight of load in truck = $150+6,000=6,150\text{ pounds}$

Hence, the truck's load weigh in total = 6,150 pounds.

A line contains the points (-9,-7) and (13,-19). Find the x-value of the x-intercept.

Karolina [17]

Answer:

x = -21.83 or (-21.83, 0)

Step-by-step explanation:

Use the given points to find the slope of the line.

$m=\frac{y2 - y1}{x2 - x1}$

(-9, -7) (13, -19)

$m=\frac{-19-(-7)}{13 - (-9)} = \frac{-12}{22} = -\frac{6}{11}$

Use the slope and one of the given points to solve the point-slope formula

$y - y=m(x-x)$

$y-(-7)=-\frac{6}{11} (x-(-9))$

$y+7=-\frac{6}{11} x-\frac{54}{11}$

$y=-\frac{6}{11} x-\frac{131}{11}$

Since you are looking for the x-intercept, set y=0 and solve for x

$0=-\frac{6}{11}x - \frac{131}{11}$

$\frac{131}{11} =-\frac{6}{11} x$

$-21.83 = x$

Nitric acid (specific gravity 1.42) costs $51.95 per liter. A student spills 5.112 kg of nitric acid in the laboratory, what is

Leno4ka [110]

Answer:

The cost of wasted nitric acid is $187.02

Step-by-step explanation:

Since it is given that specific gravity of Nitric Acid is 1.42 Thus the density of nitric acid is

$\rho _{acid}=S.G\times \rho _{water}\\\\\\\rho_{acid}=1.42\times 1\frac{g}{cm^3}\\\\\rho_{acid}=1.42g/cm^3$

Now from the basic relation of mass volume and density we have

$\rho =\frac{Mass}{Volume}\\\\\therefore Volume=\frac{Mass}{\rho }$

Since the mass of the nitric acid is given to be 5.112 kg = 5112 grams

Thus the volume of nitric acid is

$Volume=\frac{5112}{1.42}=3600cm^3$

Now we know that 1000 cubic centimeters euals 1 litrer

Thus the calculated volume in liters is

$V_{liters}=\frac{3600}{1000}=3.6Liters$

Thus the cost of acid spilled equals

$Cost=3.6\times 51.95=187.02$
