Answer:

Step-by-step explanation:

To find the volume of this prism, find the area of the (white) face and then multiply it by the length of the prism.

The face is a triangle with base 8 in and height 15 in. According to the area-of-a-triangle formula, the area is A = (1/2)(base)(height), which here is:

A = (1/2)(8 in)(15 in) = 60 in^2.

Multiply this by 11 in to get the volume of the prism:

V = (60 in^2)(11 in) = 660 in^3 (this is the fourth possible answer)

Select all the expressions that are equivalent to −5/6 / -1/3

Sindrei [870]

Step-by-step explanation:

We need to find an expression for $\dfrac{\dfrac{-5}{6}}{\dfrac{-1}{3}}$ .

We can solve it as follows.

We know that,

$\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}$

So,

$\dfrac{\dfrac{-5}{6}}{\dfrac{-1}{3}}=\dfrac{-5}{6}\times -3\\\\=\dfrac{5}{2}$

$=2\dfrac{1}{2}$

Hence, this is the required solution.

Eric and Linda are paid 52.25 for they're work. Eric worked 3.5 hours, and Linda worked 2 hours. They split the money according

Ne4ueva [31]

Answer:

$33.25

Step-by-step explanation:

Taking Eric's hours as a ratio to the total hours :

3.5 : 3.5 + 2
3.5 : 5.5
3.5 x 2 = : 5.5 x 2
7 : 11

Multiply the ratio into the amount paid :

52.25 x 7/11
4.75 x 7
$33.25

Eric's share of the money is $33.25

Jake drove 300 miles from his house to a soccer tournament. This graph shows the distance Jake had traveled (m) and the time tha

Bad White [126]

Part A. The trip starts at 8am which corresponds to 0 hrs, point (0hr, 0mi)

2hrs later it's 10am. .point (2hr, 140mi)

The average speed is the slope between 0 and 2 hrs. Remember the slope formula m = Δy/Δx

m = (140 - 0) / (2 - 0)

m = 70 mph

Part B. Average speed from 11am - 2pm

11am is point (3hr, 140mi)

2pm is point (6hr, 300mi)

As you can see from the graph, the speed or slope changes at 1pm (5,260). You Can just use the start and end points.

m = (300-140) / (6-3)

m = 160/3

53.3 mph

* It comes out the same solution as if you average the two different slopes. 2hrs at 60mph + 1 hr at 40mph = (120 + 40)/3 = 160/3

Part C. Total average speed = total distance / total time driving

He went 70 mph for 2 hrs

stopped for an hour (slope is zero, no speed)

60 mph for 2hrs

40mph for 1 hr

300mi /5hr = 60mph

Part D. No Question....
