Answer:

4/5 or 0.8

Step-by-step explanation:

so, -4/4 and 1/5 are both already fractions.

160% as a decimal would be 1.6. 1.6 as a fraction would be 8/5.

-4/4 is just -1

-1+1/5+8/5

so, -5/5 +1/5 +8/5

-5/5 plus 9/5

4/5

the answer would be 4/5 or 0.8

Renita started her homework at 3:45 P.M. She worked for 2 hours and 15 minutes. What time did she finish her homework?

Flauer [41]

Answer:

6:00 or 6 o'clock

Step-by-step explanation:

1) Add 2 to the hours. So, 3+2=5

2) Add 15 minutes to 45 minutes. So, 15+45=60

3) 60 minutes is an hour, so therefore add one more hour. 5+1=6

4) There are 6 hours and 0 minutes.

So, the time that Renita finished her homework was 6:00.

A basketball player makes 80% of her free throws. The random numbers below represent 20 trials for

Taya2010 [7]

Answer:

0.6

Step-by-step explanation:

The numbers 0 to 7 represent a made free throw
The numbers 8 to 9 represent a missed free throw.

Given the simulation data

(8,2) (9,3) (4,0) (5,8) (2,7) (2,0) (5,4) (8,0) (0,4) (9.1)

(9,6) (6,5) (4,4) (1,7) (0,4) (8,5) (8,8) (1,7) (3,5) (0,3)

A pair that contains only numbers between 0 and 7 shows the player makes both throws.

These pairs are:

(4,0) (2,7) (2,0) (5,4) (0,4) (6,5) (4,4) (1,7) (0,4) (1,7) (3,5) (0,3)

There are a total of 12 cases where the player makes both throws.

Therefore:

P(Player makes both throws)=12/20=0.6

In preparing a certain ointment, a pharmacist used 28.35 g of zinc oxide instead of the 31.1 g called for. Calculate the percent

Vilka [71]

Answer: 9.70%

Step-by-step explanation:

The formula to find the percentage error is given by :-

$\%\text{ error}=\dfrac{|\text{Estimate-Actual}|}{\text{Actual}}\times100$

Given : Actual mass of zinc oxide used by pharmacist = 28.35 g

Estimated mass of zinc oxide used by pharmacist =31.1 g

Now, $\%\text{ error}=\dfrac{|31.1-28.35|}{28.35}\times100$

i.e. $\%\text{ error}=\dfrac{2.75}{28.35}\times100$

i.e. $\%\text{ error}=9.70017636684\approx9.70\%$

Hence, the percentage of error on the basis of the desired quantity.= 9.70%
