85 + 45 = 130
130km in 1.5 hours
130 / 1.5 = 86.6666666666666
the average speed was:
86.6666666666666
a brainliest would be appreciated
The answer that best completes the statement above is COST-EFFECTIVE ANALYSIS. Occasionally, DUI checkpoints, also known as sobriety checkpoints are being established by police on the roadsides for safety purposes. This is also the same with the seatbelt laws. Both of these aim in decreasing motor-vehicular accidents. Comparing these two, we call it cost-effective analysis. When we say cost-effective, the effectivity of the action if being assessed in relation to the cost it takes to enforce the rule.
Answer:
104 kWh
Explanation:
To calculate the kWh you multiply power with the amount of hours.
So for this we take 5200 W × 20 = 104 000 Wh
Then change Wh to kWh so that makes 104 kWh
Thank you for posting your question here at brainly. Below is the answer:
sum of Mc = 0 = -Ay(4.2 + 3cos(59)) + (275)(2.1 + 3cos(59)) + M
<span>- Ay = (M + (275*(2.1 + 3cos(59)))/(4.2 + 3cos(59)) </span>
<span>sum of Ma = 0 = (-275)(2.1) - Cy(4.2 + 3cos(59)) + M </span>
<span>- Cy = (M - (275*2.1))/(4.2 + 3cos(59)) </span>
<span>Ay + Cy = 275 = ((M+1002.41)+(M-577.5))/(5.745) </span>
<span>= (2M + 424.91)/(5.745) </span>
<span>M = ((275*5.745) - 424.91)/2 </span>
<span>= 577.483 which rounds off to 577 </span>
<span>Is it maybe supposed to be Ay - Cy = 275</span>
