A machine produces 440 bolts in 48 minutes. At the same rate, how many bolts would be produced in 30 minutes?

1 answer:

3 0

The units you want is $\frac{bolts}{min}$ , so you set up the following equation:
$\frac{440\ bolts}{48\ mins} = \frac{x}{30\ mins} \\
440*30=48*x\\
13200=48x\\
x=\frac{13200}{48}=275 \frac{bolts}{min}$

-3/4

To calculate slope, use the formula

Slope (m) = y2 - y1/x2 - x1

Then choose two points on the line of the graph (as shown in attached file)

Input the values as read from the graph and solve for slope using the graph

Note that the discrepancy in answer is due to the assumption made, no value was given on the graph.

Find the volume of the following solid:

Nadya [2.5K]

Answer:

390cm³

Step-by-step explanation:

IF you look at the figure attached, you will see that your figure is made up of 3 rectangular prisms.

All you need to do is solve for the volume of each prism and add them up together.

The formula to use to get the volume of a rectangular prism is:

$V=whl$

Where:

V = Volume

w = width

l = length

h = height

Let's get the first one and double it because you have rectangular prisms with the same dimensions:

$V = wlh\\\\V= (5cm)(2cm)(12cm) = 120cm^3\\\\120cm^3 \times 2=240cm^3$

Next we get the rectangular prism in the middle:

Notice that the height of the side rectangular prisms is 12 cm. To get the height of the middle figure, just subtract 5cm and 2 cm from the height because they are the excess of the middle.

12cm - (5cm + 2cm)

12 cm - 7cm = 5cm

Then we plug it into the formula

$V = wlh\\\\V= (5cm)(6cm)(5cm) = 150cm^3$
