4 divided by 236 equals to 0.016
If you mark up 584 by 25%, you get 730. Therefore, the price of the refrigerator after the markup is $730.
An equation for annealing soda-lime glass is y(t)=−14t+500 , where t is time in minutes and y is the temperature of the glass in ˚C.
To find the y intercept , we plug in 0 for t
y intercept is the value , where time is 0 minutes
so we plug in 0 for t and find out y(0)
y(t)=−14t+500
y(0)=−14(0)+500 = 500
When t=0 , the value of y = 500
So , y intercept is (0,500)
It would be 80% since it decreases 20% each year so 20*4 is 80 so it’s 80%
