Answer:
Step-by-step explanation:
<h3><u>Formula to be used in the question:</u></h3>
<h3><u>Distance for the first 2 hours:</u></h3>
= 130 km
<h3><u>Distance for the next 3 hours:</u></h3>
Speed = 85 km/h
Time = 3 hours
So,
Distance = Speed × Time
Distance = 85 × 3
Distance = 255 km
So,
<h3><u>Total distance from home to destination:</u></h3>
= 130 + 255
= 385 km
<h3><u>Speed on the return journey:</u></h3>
Total distance = 385 km
Time = 5 hours
Speed = Distance / Time
Speed = 385 / 5
Speed = 77 km/hr

Answer: 230. 34 times five is 170. Then you are left with 170 + 3 + 43 + 4 + 3 +4 + 3. You can combine the 3's and you get 9. You are left with 179 + 4 +4 + 43 You combine the 4's and you get 187. 187 + 43 = 230.
Answer:
1,395 sq feet
Step-by-step explanation:
lets start with the area of the green cube b×h. 15×15=225. 225×5= 1125. I got five because there are 5 visible faces on the cube. to find the area of a triangle you use the formula 1/2 bh 9×15= 135 multiply that by 2 instead of one half because you have four triangular faces. add your areas together and you get 1395
The simplified form of this polynomial is (n(20n + 1))/5
So we know d. is out and that's all I got help wise sorry its not much..:)
