HELP MEEEE !!! Plsssss

1 answer:

6 0

Answer: option B

This is because you have to work out the range of both periods

The range is the highest number - the lowest number

Range for period 1: 92-81=11
Range for period 3:92-74=18

As you can see the range for period 3 is 7 points greater than period 1 therefore the answer is the second option ( option B)

Hope this helped

Which system is equivalent to 3x squared - 4y squared = 25 over -6x squared -2y squared = 11

TEA [102]

So we are given the following system:
$3x^2-4y^2=25\\
-6x^2-2y^2=11\\\text{Multiply the second equation by -2:}\\12x^2+4y^2=-22\\\text{Add to the first equation we get:}\\15x^2=3
\text{ therefore }x=\pm \sqrt{ \frac{1}{5} }$
Using the first equation again we get:
$3x^2-4y^2=25\\
3x^2=4y^2+25\\
x^2= \frac{1}{3}(4y^2+25)\\x^2= \frac{1}{3}(4 \frac{1}{5} +25)\\= \frac{43}{5}\\x=\pm \sqrt{ \frac{43}{5} }$

Bobbi can mow the park in 3 hours and Deshaun can do the same job in 7 hours. How long will it take them to mow the park

Bogdan [553]

Answer:

2.1 hours (2 hours and 6 minutes)

Step-by-step explanation:

The rate of work of Bobbi is ⅓ while for Deshaun is 1/7 hence combined rate will be

⅓+1/7=(7+3)/21=10/21

The equivalent hours is the reciprocal of the above hence 1021/10=2.1 hours

0.1 of an hour is equivalent to 0.1*60=6 minutes

Therefore, the efforts combined will take 2.1 hours or 2 hours and 6 minutes
