दोन लघुकोन परस्परांचे कोटीकोन असु शकतील का |
|
Answer» एका सरळ रेषेत नसलेले तीन बिंदु सरळ रेषांनी जोडून तयार झालेल्या आकृतीस त्रिकोण म्हणतात. या रेषांना त्रिकोणाच्या बाजू म्हणतात. त्रिकोणाच्या आकृतीतील सर्वात खालच्या बाजूला त्रिकोणाचा पाया म्हणतात. सर्वात वरच्या कोनबिंदूला शिरोबिंदू. शिरोबिंदूपासून पायावर टाकलेल्या लंबरेषेच्या, शिरोबिंदू ते पाया या लांबीला त्रिकोणाची उंची म्हणतात. त्रिकोणाच्या तिन्ही कोनांची बेरीज १८० अंश असते. त्यामुळे कोणतेही दोन कोन माहीत असल्यास तिसरा कोन सहज काढता येतो. त्रिकोणाच्या सर्वात मोठ्या बाजूसमोरील कोन सर्वात मोठा असतो. त्रिकोणाचा पाया व उंची माहीत असल्यास त्या त्रिकोणाचे क्षेत्रफळ काढता येते. आशा आहे की हे आपल्या शंका दूर करेल!! |

|
Answer» Step-by-step explanation: (m−1) m
=N if logm+logn=log(m+n), FIND m in TERMS of n We can write this as: log(mn)=log(m+n) ∴mn=m+n Subtracting n from both the sides we get, mn–n=m n(m−1)=m m−1 m

What is radius of cylinder of height 20cm formed by melting sphere of radius 15 cm |
|
Answer» Step-by-step EXPLANATION: VOLUME of cylinder = Volume of sphere π×r^2×h = 4×π×r^3/3 r^2×20 = 4×15^3/3 (π CUT down from both sides) r^2 = 4×15×15×15/3×20 r^2 = 13500/60 r^2 = 225 r = √225 r = 15 Hence, radius of cylinder is 15 cm. |

In the first box there are 5 white, 3 red and 2 green balls. In the second box there are 2 white, 4 red and 3 green balls. We take one ball out of the first box and transfer it to the second box, and then we draw three balls from the second box. If all the balls drawn from the second box were different colour, what is the probability that the ball we transferred from the first to the second box was red? |
|
Answer» Answer: Correct option is A 16 7
For the bag A we can see that there are 2 white, 3 red and 2 BLACK BALLS. SIMILARLY, from bag B we have 4 white, 2 red and 3 black balls. Probability of choosing a white and then a red ball from bag B is given by = 9 C 2
4 C 1
× 2 C 1
Probability of choosing a white ball then a red ball from bag A is given by = 7 C 2
2 C 1
× 3 C 1
So, the probability of getting a white ball and then a red ball from bag B is given by 9 C 2
4 C 1
× 2 C 1
+ 7 C 2
2 C 1
× 3 C 1
9 C 2
4 C 1
× 2 C 1
= 7 2
+ 9 2
9 2
= 18+14 2×7
= 16 7

If a^b=17 and a-b =1 then a,b are |
|
Answer» Answer: if a^b=17 and a-b =1 then a,b are We are given a system of two linear, simultaneous equations in two unknowns, a and b: a+ b = 19 and a - b = 1. To solve for the UNKNOWN a, we'll use the Elimination Method (Addition/Subtraction Method) as follows to get rid of the variable b: Adding the two equations, we get: a + b = 19 a - b = 1 --------- 2a + 0 = 20 2a = 20 (2a)/2 = 20/2 (2/2)a = 20/2 (1)a = 10 a = 10 The student should continue using the Elimination Method(Addition/Subtraction Method) by subtracting equation a - b = 1 from a + b = 19 to see that b = 9, and then substituting a = 10 and b = 9 into BOTH of the given equations to see that the ordered-pair solution (a, b) = (10, 9) makes BOTH equations true. 1K views View upvotes 1 Related Questions (More ANSWERS Below) |

.If there are 10 more students, i.e. (x+10) students. Then, the number of apples received by each student is x+10 300
. ACCORDING to the question, x 300
− x+10 300
=1 ⇒ x(x+10) 300x+3000−300x
=1 ⇒3000=x 2 +10x ⇒x 2 +10x−3000=0 ⇒x 2 +60x−50x−3000=0 ⇒x(x+60)−50(x+60)=0 ⇒(x+60)(x−50)=0 ⇒x=−60 or x=50 |
