ANSWER:

B  & 8

Step-by-step explanation:

rule :

If a card has a consonant on one SIDE, then it has an odd number on the other side

We need to just turn Card MENTIONING B  & 8

B is a consonant so it Should have odd number on back side

8 is not an odd number so it should have a vowels on back side

We need not to turn 3 as it is an odd number , if consonant is on back side , its good , even if its not consonant , then no rule defined for VOWEL back side.

U is a vowel and has no rule for back side

so we need to turn B & 8

we need no

For, v = velocity, m = mass of man.

Kinetic Energy (KE) = 1/2 m v^2

So, v = (2 KE / m)^1/2

v = (2 . 750 / 60)^ 1/2

v = (25)^1/2 = 5 m/s

Answer:

Step-by-step explanation:

Selection of 5 out of 7 and PERMUTING them.

Answer is 7C5*5=105

Let the work of women be x.
let the work of manln be y.

Therefore,
let both in one day be,
2/x + 5/y = 1/4............... (i)
condition 2:
3/x + 6/y = 1/3......... (ii)

let 1/x be a and 1/y be y.

from (I) and (ii),
(2a +5b =1/4) * 3
(3A + 6b = 1/3) * 2

6a +15b = 3/4. ( subtract (ii) from (i) )
6a +12b = 2/3

3b= 3/4 - 2/3
3b= 9-8/12
b= 1/12*3
b = 1/ 36
therefore,
1/y = b
y = 1/b
y = 36 days

2a + 5b = 1/4
2a + 5 / 1/36 = 1 /4
(72A + 5)/36=1/4
72a + 5 =9
72a = 4
a = 4/72
a = 1/18

1/x = a
x= 18


therefore work of one man is 36 days and work of one woman is 18 days.

Because sin=Opp.angle/ HYPOTENUSE
so. SIN30 = X/2x
so. sin30 =1/2

because COS=adj.angle/hypotenuse
so cos 60= X/2x
so. COS60 =1/2

-10/3 is the VALUE of X

First you will have to find the discriminant of the equation by using b^2 - 4AC ..
if the answer is a perfect root of some number then your answer will be REAL ... if the root is not a perfect root of some number then your answer will consist of so.e complex no like √2 etc..
after finding the D ..
PUT on the formula -b +_ √ b^2 - 4ac

So 0.08, the decimal part of the decimal quotient, must equal THEREMAINDER, 14, divided by the divisor J. 2) USE the rule dividend = (integerquotient)*(divisor) + REMAINDER totranslate each sentence. The first sentence BECOMES N = 18P + 7.

By the FACTORS which FORM the no PERFECT SQUARE no.

A+B+3y is THRICE of y ADDED to SUM of a and b

O its very easy
SEE ;
when we DRAW SQUARE
we see that all the angles of a square is of 90 degree
HENCE they are perpendicular to each other.
and if they have angles of 90 degree then there diagonals will also. be equal.

The NUMBERS are 165 and 99

Ritu can row downstream 20 km in 2 hours
so, SPEED of downstream,
Sd = 20/2 = 10km/h

Ritu can row upstream 4 km in 2 hrs
so, Speed of upstream,
Su = 4/2 = 2km/h

Speed of the boat in still WATER = 1/2( speed of downstream - speed of upstream) = 1/2( 10+2) = 1/2(12) = 6KM / hr

Speed of the stream = 1/2( speed of downstream - speed of upstream) = 1/2(10-2) = 1/2(8) = 4km/hr

The VALUE of a=-6 and B = -√5

let ONE NUMBER be X

other number be x + 11

the other number be x + 22

x + x + 11 + x + 22 = 363

3x + 33 = 363

3x = 363 - 33

3x = 333

x = 111

x + 11 = 122

x= 22 = 133

hope it helps you mate<3<3

please MARK as brainliest

The VALUE of a=-6 and value of b=-√5

SOLUTION

TO PROVE

If A ⊆ B then A × C ⊆ B × C

EVALUATION

Let (x, y) ∈ A × C

⇒ x ∈ A ∧ y ∈ C

⇒ x ∈ B ∧ y ∈ C ( ∵ A ⊆ B )

⇒ (x, y) ∈ A × C

∴ A × C ⊆ B × C

Hence PROVED

I don't KNOW about this

The PERFECT CUBE of 142884 is 278

I can definitely say there exist no such positive even INTEGERS, Whose sum is 0,

If you think negative integers are ALSO classified as even and odd, Then the solution is,

LET three consecutive even integers be

X-2, X, X+2,

according to data, their sum is 0,

(X-2) + (X) + (X+2) = 0,

3X = 0,

X = 0,

Now the three integers are -2, 0, +2 !!
