In triangle abc, the median ad is perpendicular to BC. Prove that ABC is a isosceles triangle . |
|
Answer» Answer:Consider triangles ABD and ACD. As AD is a median of ABC, D is the midpoint of BC. So BD = CD. The side AD is common to both triangles. If AD is perpendicular to BC, then ∠ADB = 90° = ∠ADC. So by the SAS RULE, triangles ABC and ACD are congruent. Therefore AB = AC. It follows that ABC is isosceles Please mark it brainliest And plzz thanks Step-by-step EXPLANATION: |

A man took 2 hours 10 minutes to drive from Town A to Town B, and 1 hour 15 minutes to drive back. Determine the percentage change in his speed two 2 decimal places. |
|
Answer» Step-by-step explanation: In this lesson, we will investigate the relationship between the distance traveled, the rate or speed or travel, and the time that it takes to travel that distance at that rate. We will also look at a few other related products. Distance = (Rate)(Time) The equation that relates distance, rate, and time is d = rt Where d is the distance traveled, r is the rate, and t is the time. On the CAHSEE exam, you will be given two of these and will be asked to use the above equation to find the third. Example 1 It took Markus half an hour to drive home from WORK. He averaged 34 miles per hour. How far does Markus live from his work? Solution We are given that it takes 1/2 an hour for the trip. This is a time: t = 1/2 We are given that he averages 34 miles per hour. This is a rate: r = 34 We are asked how few he has traveled. This is a distance. We use the d=rt equation: d = rt = (34)(1/2) = 17 Markus lives 17 miles from work. Now try one by yourself. If you want to see the answer, put your mouse on the yellow rectangle and the answer will appear. Exercise 1 The current along the beach is moving towards the south at 1.5 miles per hour. If a piece of DEBRIS is placed into the water, how far will the current take it in 6 hours? 9 miles Example 2 Elena always rides her bicycle at a speed of 15 miles per hour. On Sunday, she goes on a 24 mile bike ride. How many hours does this ride take? Solution The speed of 15 miles per hour is a rate. The key words that tell us that this is a rate are "speed" and "miles per hour". We can write: r = 15 Next, 24 miles is a distance. We have: d = 24 Now use the d=rt equation to get 24 = 15t To SOLVE this, DIVIDE both sides by 15 to get t = 24/15 Both are divisible by 3, so this fraction reduces to t = 8/5 = 1.6 Elena's ride takes 1.6 hours. |

Hii hlo. pls tell me prove that 5-3/7√3is irrational |

Answer» Proving: let 5-2/7√3 be rational no. therefore 5-2/7√3=p/q (where p and q are co PRIME) 2/7√3=5-p/q 2/7√3=5q-p/q √3=7(5q-p)/2q here 7,5,2,q,and p are integers. therefore 7(5q-p)/2q is rational therefore √3 is rational no but this contradicts the FACT that √3 is irrational no therefore 5-2/7√3 is irrational no. hence proved.

kangaroo jumps and lands exactly 22 feet away at a time. What is the least number of jumps required to reach a point 7 feet away? 5 points321Not possible to travel such distance |
|
Answer» Given : kangaroo jumps and LANDS exactly 22 FEET away at a time To find : least number of jumps required to reach a point 7 feet away Solution: kangaroo jumps and lands exactly 22 feet away at a time least number of jumps required to reach a point 7 feet away is 2 As kangaroo jumps exactly 22 feet and he has to go 7 feet away hence in 1st jump its not possible in 2 jump Kangaroo can can reach 7 feet Let say A kangaroo is at point A and he has to go point B at 7 feet distance He will jump at point C which will be at 22 FT distance from A & B Then from C he will jump 22 feet to reach B which is at 7 feet from A . Hence at least two jumps are required by kangaroo to reach a point 7 feet away 2 Jumps Learn more: we know in a triangle sum of any two sides is greater than the third ...

10. Find area of a rectangle in m², whose length is 3400cm and breadth 720 cm. |
|
Answer» Step-by-step EXPLANATION: Hi !!! This is a REALLY easy question but the only thing you need to concentrate is the calculation and conversion of units. So, here we go, Given, Breadth = 720cm = 7.2m We know that the area of a rectangle = Length * Breadth = 34m*7.2m = 244.8m^2 Thus the area of a rectangle in m^2 is 244.8m^2. If you mark this answer as brainliest answer, it WOULD make my day!!! Hope it helps!!! |
