Is it more difficult to run up a ramp with a slope of 1/5 or a ramp with a slope of 5? Explain.
VARVARA [1.3K]
It would be more difficult to run up a slope of 5 because it would be steeper. with a 1/5 slope you would have a rise over run but with a slope of 5 it would just be all rise

The product of two integers is 72.one number is two less than 5 times the other
harkovskaia [24]
X*y=72
x = 5y-2

x=72/y
72/y=5y-2

72=5y^2-2y
5y^2 -2y - 72 = 0
(5y+18)(y-4)=0
y = -18/5 discard
or y = 4
4x=72
x=18

12+root of 35 divided by 2 + 12-2 root of 35 divided by 2
nadya68 [22]
So : 12+ \frac{\sqrt{35}}{2} + \frac{12-2 \sqrt{35} }{2}?

First, you want to bring everything together on the top of the fraction. 
12=24/2 so you can have \frac{24+ \sqrt{35}+12-2 \sqrt{35} }{2}

Add like terms -- 12 +24 = 36       \sqrt{35}-2 \sqrt{35} = \sqrt{35}

Now we are at \frac{24+ \sqrt{35} }{2} Which is the lowest possible simplified version while remaining at exact value. 

Feel free to check my math! I kinda did this off the top of my head.

A solution is heated from 0°C to 100°C. Between 0°C and 50°C, the rate of temperature increase is 1.5°C/min. Between 50°C and 10
muminat

Answer:

0.6 °C/min

Step-by-step explanation:

The relationship between rates and movement is ...

time = distance/speed

Here, the "distance" is measured in °C, and the "speed" is the rate of change of temperature.

For the first half of the heating, the time required is ...

(50°C -0°C)/(1.5 °C/min) = 50/(3/2) min = 100/3 min

For the second half of the heating, the time required is ...

(100°C -50°C)/(4/10 °C/min) = 50/(4/10) = 125 min

Then the total time is ...

((100/3) +125) min = (475/3) min

And the average rate of temperature increase is ...

total temperature change / total time

= (100°C -0°C)/(475/3 min) = 300/475 °C/min = 12/19 °C/min ≈ 0.6 °C/min
