Simplify the expression.
OlgaM077 [116]

Answer:

5.1

Step-by-step explanation:

-44.288-31.6 / -3.1(6-1.2)

Add -44.288 and -31.6

= -75.888 / -3.1(6-1.2)

Subtract 1.2 from 6

= -75.888 / -3.1(4.8)

Multiply -3.1 and 4.8

= -75.888 / -14.88

Divide -75.888 by -14.88

-75.888 / -14.88

=5.1

vivado [14]

Answer:

Arnold descended a distance of 5,250 ft after his parachute opened

Step-by-step explanation:

Here in this question, we want to know the distance Arnold descended after his parachute opened.

Mathematically, we know that distance = speed * time

In this case;

The speed is the rate at which he descended = 70 ft per second

Now the time is 1 minute and 15 seconds; since 1 minute is 60 seconds, then 1 minute and 15 seconds is 60 + 15 = 75 seconds

So what we are saying is he descended at a rate of 70 ft per second for 75 seconds

Thus, his distance of descent will be 70 ft per second * 75 seconds = 5,250 ft

lukranit [14]
The stem and leaf plot will look like:
6 | 1 5 8 - 3 scores
7 | 1 7 7 9 - 4 scores
8 | 2 3 4 5 7 9 - 6 scores
9 | 0 1 4 7 9 - 1 score
To total up the number of students who scored less than 90, we have 3 under 60-69, 4 under 70-79, and 6 under 80-89, so this is 3 + 4 + 6. This is the third choice.
