You are driving home on a weekend from school at 55 mi/h for 110 miles. It then starts to snow and you slow to 35 mi/h. You arri

Gemiola [76]

SOLUTION:

If you drive at 55 mi/h for 110 miles, this means you drovefor 110 / 55 = 2 hours

Your total driving time is 4 hours and 15 minutes which meansthat you drove 2 and 15 minutes at the rate of 35 mi/h

2 hours and 15 minutes = 2×60 + 15 = 135minutes

35 miles / 60 minutes × ( 135 minutes) = 78.75miles

So total miles driven is 78.75 + 110 =188.75 miles

Someone please help me. SERIOUS answers only.

So, we need to know what the unit rate. Basically, how many miles in 1 hour is what we are looking for. To do this, we must use the data given. Let's do 2 hours. So, we have to divide 2 hours by 36 miles. 36/2 is 18. So, 18 miles per hour is our unit rate. Now, we need to find how many miles in 8 hours. So, we need to multiply 18 miles (because that's 1 hour) by the number of hours we need, which is 8 in this case. So, 18*8 is equal to 144. So, 144 miles is the distance traveled in 8 hours. Hope this helped!

Answer:

The position of Michael's hands relative to the surface of the water is -1.3 meters.

Step-by-step explanation:

The question is incomplete, so below is the complete question?

Michael is doing an underwater handstand. His feet are sticking up 0.5 meters above the surface of the water. Michael's hands are 1.8 meters directly below his feet. What is the position of Michael's hands relative to the surface of the water?

Now, to find the position of Michael's hands relative to the surface of the water.

Meters of Michael's hands directly below his feet = 1.8 meters.

Meters of his feet sticking above the surface of the water = 0.5 meters.

So, to get the position of Michael's hands relative to the surface of the water we subtract meters of Michael's hands directly below his feet from meters of his feet sticking above the surface of the water:

$0.5\ meters\ -\ 1.8\ meters\\\\=-1.3\ meters.$

Therefore, the position of Michael's hands relative to the surface of the water is -1.3 meters.

6+x6+x 6+x 6, plus, x when x=3x=3 x=3 x, equals, 3 .

fgiga [73]

Answer:

$2196$

Step-by-step explanation:

Okay so we have $6+x^{6} +x^{6} +x^{6} +x$ when $x=3$ since we know that $x=3$ we can rewrite the problem as $6+3^{6}+3^{6}+3^{6}+3$ then it can be rewritten as $(6+3)+(3*3^{6})$ which would then become $(9)+(3*729)$ then $(9)+(2187)$ which finally equals $2196$ .
