konstantin123 [22]

Answer:

He would need to run 5/12 more miles to reach his goal.

Step-by-step explanation:

You want to get all your fractions to the denominator of 12.

1/2 = 6/12

1/4 = 3/12

2/3 = 8/12

Then you would want to add them all up, 6/12+3/12+8/12 = 17/12.

Then you subtract his goal of 22/12-17/12, to get your answer of 5/12.

Hope this helps! :)

What is the volume of a rectangular prism with a length

lana [24]

The volume of the rectangular prism is 1 $inch^{3}$ , If the rectangular prism have a length of 2 inches, a width of 1 inch, and a height of 1/2 inch.

Step-by-step explanation:

The given is,

Let, l - Length of the rectangular prism

w - Width of the rectangular prism

h - Height of the rectangular prism

Step:1

From the given,

l - 2 inches

w - 1 inch

h - $\frac{1}{2}$ inch

Step:2

Formula for the volume of a rectangular prism is,

$V = w h l$

Substitute the values of the w, h and l

= ( 1 × $\frac{1}{2}$ × 2 )

= 1

V = 1 $inch^{3}$

Result:

Thus the volume of the rectangular prism is 1 $inch^{3}$ , for the given rectangular prism have a length of 2 inches, a width of 1 inch, and a height of 1/2 inch.

Jason is scuba diving at a constant rate toward the ocean floor. The equation

Anon25 [30]

Answer:

Jason started scuba diving 5 meters below sea level and is descending at a rate of 2.5 meters per second.

Step-by-step explanation:

Jason is scuba diving at a constant rate toward the ocean floor.

Equation: $y= -2.5x- 5$

x = The number of seconds Jason has been swimming.

y=The depth of Jason in meters below sea level

General equation : y=mx+c

m = Slope = rate of change per unit

On comparing m = -2.5

Negative signs represents the descending .

So, rate of descending per second = 2.5 m/sec

-5 denotes the initial position below sea level

So, Option D is true

So, Jason started scuba diving 5 meters below sea level and is descending at a rate of 2.5 meters per second.
