1.

If the ordered pairs (x - 1, y + 3)and (2, x + 4)are equal, find x and y.a) 1.4b) 3.4c)3.7d) 3.2​

Answer»

ANSWER:

x-1,y+3=x+4,2.

so x-1-x+4 = y-3+2.

3=y-1y=2

x-1,y+3=x+4,2

x-1,2+3=x+4,2

x-1,5=x+4,2

2x=3

x=3/2

x+y =1.5+2=3.5. it is CLOSE to 3.4 so answer should be B)3.4

2.

किसी विद्यालय के विद्यार्थियों से एक आधार वाले बेलनाकार कलमदानों को गत्ते से बनाने और सजाने की प्रतियोगिता में भाग लेने के लिए कहा गया। प्रत्येक कलमदान को 3 cm क्रिया और 10.5 cm ऊँचाई का होना था। विद्यालय को इसके लिए प्रतिभागियों को गत्ता देना था। यदि इसमें 35 प्रतिभागी थे, तो विद्यालय को कितना गत्ता खरीदना पड़ा होगा?

Answer»

ANSWER:

विद्यालय को 7920 cm² गत्ता प्रतियोगिता के लिए खरीदना आवश्यक है।

Step-by-step explanation:

दिया है :  

प्रत्येक कलमदान की त्रिज्या, (R) = 3 CM

प्रत्येक कलमदान की ऊँचाई ,(h) = 10.5 cm

प्रत्येक प्रतिभागी के लिए आवश्यक गत्ता = एक कलम दानी का वक्र पृष्ठीय क्षेत्रफल + आधार का क्षेत्रफल  = 2πrh + πr²  

= [(2 × 22/7 × 3 × 10.5) + 22/7 × 3²]  

= [44 × 3 × 1.5 + 22/7 × 9 ]

= [132 × 1.5 + 198/7]

= (198 + 198/7)  

= 1584/7 cm²

प्रत्येक प्रतिभागी के लिए आवश्यक गत्ता = 1584/7 cm²

∴ 35 प्रतिभागियों के लिए आवश्यक गत्ता  = (35 × 1584/7) cm² = 7920 cm²

अतः विद्यालय को 7920 cm² गत्ता प्रतियोगिता के लिए खरीदना आवश्यक है।

आशा है कि यह उत्तर आपकी मदद करेगा।

a triangle whose two sides are 60 cm and 100 cm with perimeter of 300 cm find the area with heron's formula​

Answer»

HEYA USER ❤️

AB = 60 CM(a)

BC = 100 cm(b)

CA = ?

PERIMETER = AB+BC

+CA

300 = 60+100+CA

300=160 + CA

300-160=CA

CA = 140 cm(c)

NOW,

SEMI PERIMETER = PERIMETER/2

= 300/2

=150

BY USING HERON'S FORMULA,

Ar. = [s(s-a)(s-b)(s-c)]

Ar. = [150(150-60)(150-100)(150-140)]

Ar. = [150×90×50×10]

Ar. = [5×3×2×5×3×3×2×5×5×5×2×2×5]

Ar. = 5×3×2×5×5×23

Ar. = 750×23

Ar. = 2598.076 cm² ( required answer )

Locate root 4.1 on number line...

Answer»

Given :   root 4 .1     √4.1

To find  : represent on NUMBER line

Solution:

Step 1  :  Draw a number line  AOB    ( O being 0)

Step 2 : Take a length of 4.1 cm from O on left side mark it M

Step 3 : Take 1 cm from O on right side  , mark it N

Step 4 : Using suitable compass width draw arcs on both sides of MN taking M & N as center & intersecting at X & Y

Step 5 : join X & Y intersecting MN at  P  

Step 6 :  Draw a semicircle taking P as center & PM = PN as radius ( compass width)

Step 7 : Draw a right angle at AO  such that it intersect semicircle at  Z

OZ = √4.1

Step 8 : Taking compass width = OZ  and taking O as center  cut the number line on right side at C

point C  represent  √4.1 on a number line

Mathematical proof

Semicircle radius  =  (4.1 + 1)/2  =  5.1/2  ( hypotenuse)

5.1/2 - 1  = 3.1/2  = Base

Perpendicular OZ²  =( 5.1/2)² - (3.1/2)²

=>  OZ²  = (5.1/2 + 3.1/2) (5.1/2 - 3.1/2)

=> OZ²  = 4.1

=> OZ = √4.1

Find the volume of cube whose surface area is 150. (A) 125 (B) 124 m3 (C) 121 m3 (D) 120 m3 ​

Answer»

ANSWER:

Hello Dear User__________

Here is Your Answer...!!

____________________

Step by step SOLUTION:

Given surface area is 150 \ m^2

Let SIDE be a m

We KNOW that surface area =6\ a^2

So 6\ a^2 = 150

a = 5 m

Now volume = \ a^3

volume of cube  having side 5m = \ 5^3 = 125\ m^3.

So OPTION A. is correct.

If p and q are Corrine then find hcf if p and q

Answer»

ANSWER:

Step-by-step explanation:

The “COMMON factor” of p and q is one.

Solution:

HCF: The full form of HCF is “Highest Common Factor”.

The largest common factor of TWO or more NATURAL numbers is called as “highest common factor”.

HCF is also known as “greatest common Divisor (GCD)”.

Given that  

P and q are two prime numbers

The HCF of two p and q prime numbers is one and itself.

Here the “common factor” is 1.

Therefore, the “common factor” of p and q is one.

Step-by-step EXPLANATION:

अर्थ: पूर्व वाले से एक अधिक

प्रयोग: आवर्ती दशमलव भिन्न[recurring decimal fraction],वर्ग ज्ञात करने में,आंशिक भिन्नों द्वारा समाकलन[integration by using partial fractions].

उदाहरण: --वर्ग निकालने के लिए--(यहाँ केवल 5 से अंत होने वाली संख्याओं की बात की जा रही है)--

25 का वर्ग:यहाँ पूर्व का अंक(संख्या) है 2 .----->2 का एकाधिक है 3.

अब अंतिम हल है 2x3\25------->वर्गफल के दुसरे भाग में हमेशा 25 ही होगा.

इस तरह 25 का वर्ग=625.
