Answer:

35 minutes

Step-by-step explanation:

First, we can convert everything to minutes.

10/12 of an hour

60 minutes = 1 hour

1/12 of an hour = 60/12 minutes = 5 minutes

10/12 of an hour = 1/12 of an hour * 10 = 50 minutes

1/4 hour = 1/4 of 60 minutes = 15 minutes

time doing daily exercises - time doing hiking = time doing other body exercises = 50 minutes - 15 minutes = 35 minutes

Answer:

35

Step-by-step explanation:

10/12 of an hour/60 minutes = 50 minutes so they spent that amount of time doing daily exercises

1/4 of an hour/60 minutes = 15 minutes so they spend that time hiking

subtract the 15 mins of hiking from the total 50 of exercises = 35 for other body exercises

Hope this helped!

Gwar [14]

Answer:

y=x+2

Step-by-step explanation:

the standard form is y=mx+b where m is the slope and b is the y intercept

TO FIND THE SLOPE: we take the x and y intercepts as a fraction. in this case the line touches the y axis (vertical) at point/value 2 and the x axis at point 2 as well. This means the slope is 2/2x which can be simplified to 1x or just x.

TO FIND THE Y INTERCEPT: we find where the line touches the y axis at point 2.

the slope is plugged into the m of the equation and the y intercept is plugged into the b of the equation.

The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a price tag
Step2247 [10]

Answer:

$96.15

Step-by-step explanation:

Given data

markup = 30%

cost price= $125

let the cost price before markup be x

125-30/100*x= x

125-0.3x= x

125= x+0.3x

125= 1.3x

divide both sides by 1.3

x= 125/1.3

x= $96.15

Hence the price before markup is $96.15

What 2 numbers multiply to be -14 and add to be -3
Svetach [21]
Xy = -14
x + y = -3

xy = -14
\frac{xy}{x} = \frac{-14}{x}
y = \frac{-14}{x}

x + y = -3
x + \frac{-14}{x} = -3
\frac{x^{2}}{x} + \frac{-14}{x} = -3
\frac{x^{2} - 14}{x} = -3
x^{2} - 14 = -3x
x^{2} + 3x - 14 = 0
x = \frac{-(3) \± \sqrt{(3)^{2} - 4(1)(-14)}}{2(1)}
x = \frac{-3 \± \sqrt{9 + 56}}{2}
x = \frac{-3 \± \sqrt{65}}{2}
x = \frac{-3 \± 8.06}{2}
x = -1.5 \± 4.03
x = -1.5 + 4.03    or    x = -1.5 - 4.03
x = 2.53    or    x = -5.53

        x + y = -3
   2.53 + y = -3
 - 2.53         - 2.53
              y = -5.53
        (x, y) = (2.53, -5.53)
         
         x + y = -3
  -5.53 + y = -3
+ 5.53         + 5.53
              y = 2.53
        (x, y) = (-5.53, 2.53)

The two numbers that multiply to -14 and add up to -3 are -5.53 and 2.53.
