Find the midpoint of A(5, -13) & B(10, -8).

Answer»

Answer:

15/2 , -22/2

Step-by-step explanation:

let the mid POINT be P

by mid point formula

p = (x1 + x2/2 , Y1 + y2/2)

= (5 + 10/2 , -13 - 8/2)

= (15/2 , -22/2 )

Briefly explain the transport of water and minerals in plants.​

Answer»

Answer:

Xylem- Fundamental tissue for transportation of water

In plants, minerals and water are transported through the xylem cells from soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts. The ROOT cells OBTAIN IONS from the soil which CREATES a difference in the concentration of ions between the roots and soil. Thus, there is a continuous water movement into the xylem.

Find the compound interest on Rs. 10,000 for one year at the rate of 20% per annum, if the interest is compounded quarterly. *

Answer»

Step-by-step EXPLANATION:

Principle=Rs. 10000

Rate QUARTERLY= 20/4= 5%

Time conversion PERIODS= 4

By FORMULA,

Amount=P[1+(R/100)]^T

=10000[1+(5/100)]^4

=10000[1+(1/20)]^4

=10000[21/20]^4

=10000*(194,481/160,000)

=Rs. 12155.06

Therefore,

CI=12155.06-10000=Rs. 2155.06

The angles of a triangle are in the ratio 3:5:2. Find each angle of the triangle.​

Answer»

Answer:

The angles are 54° , 90°  and 36° .

Step-by-step explanation:

let the NAME of the TRIANGLE be triangle ABC .   ---( 1)

The angle SUM of a triangle = 180 degrees .

ratio can be removed by multiplying a VARIABLE to it .

> 3:5:2 = 3x + 5x + 2x

let angle A be 3x , angle B be 5x , angle C be 2x ,now

> 3x + 5x + 2x = 180        [ refer ( 1 ) ]

> 10x = 180

> x = 180/10

> x = 18 .

now , let us find the values of the angle's ,

angle A =  3x   =>  3*18  =>  54

angle B =  5x   =>  5*18  =>  90

angle C =  2x   =>  2*18  =>  36

Therefore the angles are 54° , 90°  and 36° .

20% of 70 and 70% of 20

Answer»

Answer:

20% of 70 = 20/100 × 70

= 70/5 = 14

Hence,20% of 70 is 14.

70% of 20 = 70/100 × 20

= 70×20/100 = 70/5

=14

Hence,70% of 20 is 14 .

A two number is such that the product of its digits is 6. If 9 is added to the number, the digits interchange their places.Find the number.​

Answer»

━━━━━━ ◦ ❖ ◦  ANSWER  ━━━━━━ ◦ ❖ ◦

Let us assume  the two digit number to be ,  x + 10 y

It is ALSO GIVEN that the product of its digits is 6 , \implies x × y = 6\longrightarrow (1)

It is also told that if  9 is added to the number, the digits interchange their places ,  \implies 10x + y + 9 = 10y + x  \longrightarrow (2)

On Solving (2) ,

10x + y  + 9 = 10y + x

( 10x - x ) + ( y - 10 y ) +9 = 0

9x - 9y + 9 = 0

x − y + 1 = 0

y = x + 1  \longrightarrow (3)

Substituting the value of y in (3) in (1)

x ( x + 1 ) = 6

x² + x = 6

Now Let us SOLVE the equation , x² + x = 6

x² + x - 6

Product = -6

Sum = +1

\implies x² + 3x − 2x −6 = 0

\implies (x+3) (x−2) = 0

x = -3

and

x = 2

Therefore x = 2 , substituting x = 2 in x + 10 y we GET ,

∴ The  two digit number = 10×2 + 3 = 23

Let us Verify The Answer :-

23 + 9 = 32 , Here the digit got reversed so our answer is correct

А Aladder of 20m. high ishigh is arrangedarranged stantly to reach (touch the wall at a height of 10mfrom its foot find the angle betweenthe ladder and ground and also thedistance betweenthe foot of ladder andthefoot of the wall with process​

Answer»

Given:-

⠀⠀⠀◍ LENGTH of LADDER = 20m

⠀⠀⠀◍ Length of wall = 10m

⠀

To Find:-

⠀⠀⠀◍ Distance between the FOOT of

⠀⠀⠀⠀wall and foot of ladder.

⠀⠀⠀◍ ANGLE between the ladder

⠀⠀⠀⠀and ground

⠀

Let:-

⠀⠀⠀◍ Let ladder be = LA

⠀⠀⠀◍ Let wall be = AO

⠀⠀⠀◍ Let distance between their foot

⠀⠀⠀⠀= LO

⠀

Identity used:-

⠀⠀⠀◍ Sin Ø = \dfrac{P}{H}

⠀⠀⠀◍ Tan Ø = \dfrac{P}{B}

⠀⠀

⠀

Solution:-

★ Angle between the ladder and ground

⠀⠀⠀✯ Sin Ø = \dfrac{P}{H}

⠀⠀⠀✯ Sin Ø = \dfrac{10}{20}

⠀⠀⠀✯ Sin 30° = \dfrac{1}{2}

⠀⠀⠀✯ \fbox{ Ø = 30°}

⠀

★ Distance between their foot

⠀⠀⠀✯ Tan Ø = \dfrac{P}{B}

⠀⠀⠀✯ Tan 30° = \dfrac{P}{B}

⠀⠀⠀✯ \dfrac{1}{√3} = \dfrac{10}{LO}

⠀⠀⠀✯ LO = 10√3

⠀⠀⠀✯ LO = 17.32

⠀

⠀

So,

⠀⠀⠀★ The angle between the ladder

⠀⠀⠀⠀and ground = 30°

⠀⠀⠀★ The distance between their foot

⠀⠀⠀⠀= 17.32

10. In figure, OP perpendicular AB and OQ PerpendiAC. Prove that AO isbisector of ZCAB. ​

Answer»

Let us take Right triangle APO, right-angled at P,

OP is perpendicular to AB or APO = 90 °

Now,  

In triangle ΔAQO, right-angled at Q,

QO is perpendicular to AC or AQO = 90 °

Taking both TRIANGLES ΔAPO and ΔAQO,

AO = AO (COMMON SIDE)

APO = AQO = 90 °

AQ = AP (Perpendicular being drawn from same point O)

HENCE, by SAS (Side-Angle-Side Congruence Condition)

ΔAPO ≅ ΔAQO,

So, QAO = BAO (CORRESPONDING Parts of Congruent triangles )

Or we can conclude that AO is the bisector of \angle QAP,

Calculate the number of mole present in 10g of common table salt​

Answer»

Answer:

0.171 moles

Step-by-step explanation:

Sodium CHLORIDE , commonly known as salt or table salt, is an ionic compound with the chemical formula NACL.

Also, we know that ;

No. of moles = WEIGHT / MOLAR mass

Given: weight = 10 g

Molar mass of NaCl = 58.44 g/mol ⤵️

(22.98 + 35.45 = 58.44) g/mol

therefore,

No. of moles present = 10/58.44 = 0.171 mol
