Step-by-step explanation:

Vamsi is X years old

Vamsi = X

his brother is 3 years elder to him

Brother = X + 3

his uncle is 4 times his age

Uncle = 4X

his aunt is 5 years younger than his uncle

Aunt = Uncle - 5

what will be the age of his uncle 6 years from now

= 4X + 6

what are the ages of vamis brother, uncle and aunt?

Assume Vamis = 15 years

Brother = X + 3 = 15 +  3 = 18

Uncle = 4X = 4 * 15 = 60

Aunt = Uncle - 5 = 60 - 5 = 55

what will be the age of his uncle 6 years from now

Uncle = 4X + 6 = 60 + 6 = 66

Step-by-step explanation:

The attached graph shows the square root relation (red) and the cube root function (blue). The function values are shown for x=0 and x=±8.

You can see that there are 2 square roots for positive numbers, one square root for 0, and 0 square roots for negative numbers. There is exactly 1 cube root for any number.

Additional comment

We call the square root curve a "relation" because it is not a function. A relation that is a function will have only one y-value for each x-value. For positive x-values, there are two square roots.

y = 5/4 x + 7

Answer:

[tex]\frac{214}{6}[/tex]cm

Step-by-step explanation:

To find the perimeter of a rectangle, add all its sides.

Length + Length + Width + Width

[tex]\frac{25}{2} + \frac{25}{2} + \frac{32}{3} + \frac{32}{3}[/tex]

= [tex]\frac{50}{2} + \frac{64}{3}[/tex]

Find the LCM. It will be 6. Multiply the denominators with 2 and 3, respectively to get similar denominators, and that you can add.

 = [tex]\frac{50}{2}\frac{X 3}{X 3}[/tex] + [tex]\frac{32}{3} \frac{X2}{X2}[/tex] (the X is the multiplication sign..)

 = [tex]\frac{150}{6}[/tex] + [tex]\frac{64}{6}[/tex]

Now that the denominators are both the same, you can add the fractions.

 = [tex]\frac{214}{6}[/tex]cm ( or also 35.7cm (to 3 significant figures) or [tex]35\frac{4}{6}[/tex])

Answer:

.2 degrees

Step-by-step explanation:

180-170 is 10

10/50 is .2

The size of the other angle will be 0.2 degrees.

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

It is given that a polygon has 50 sides but one of its angles is 170 degrees.

The remaining angle will be calculated as:-

180-170 = 10

The size of the other angle is calculated below:-

Angle = 10/50

Divide the value 10 by 50 to get the angle.

Angle = 0.2

Therefore, the size of the other angle will be 0.2 degrees.

Step-by-step explanation:

let the ratio 7:8 be 7x and 8x.

now

7x+8x=30

or, 15x=30

or, x= 30/ 15

or, x= 2

here

no. of boys = 7x= 7*2 = 14

no. of girls= 8x = 8*2= 16

hope this helps u...

Answer:

16 girls

Step-by-step explanation:

sum the parts of the ratio, 7 + 8 = 15 parts

Divide the number of pupils by 15 to find the value of one part of the ratio.

30 ÷ 15 = 2 pupils ← value of 1 part of the ratio, then

8 parts = 8 × 2 = 16 ← number of girls

Answer:

[tex] \frac{2}{3} n - 11 \geqslant 17[/tex]

[tex]n \geqslant 42[/tex]

Explanation:

difference equals -

two-thirds equals 2/3

a number n equals variable of n

and 11 equals 11

at least equals _> (but like those together)

For solving equations just use photomath

The solution to the expression is n ≥ 42

An equation, statement of equality between two expressions consisting of variables and/or numbers

An equation is a mathematical expression that contains an equals symbol.

Equations often contain algebra.

Algebra is used in maths when you do not know the exact number in a calculation.

Translating the equation

[tex]\rm \dfrac{2}{3} \;n-11 \geq 17[/tex]

[tex]\rm \;n \geq (17 + 11)\times\dfrac{3}{2}\\\\\\ n \geq 42[/tex]

Answer:

The right answer is x = 8, y = 40.

Step-by-step explanation:

Since this triangle is isosceles we know that...

∠ACB = ∠ABC

40° = (5x)°

40 = 5x

x = 40 / 5

x = 8

We also know that the sum of all angles inside the triangle is equal to 180°, therefore...

∠BAC = 180° - ∠ACB - ∠ABC

(2y + 20)° = 180° - 40° - 40°

2y + 20 = 100

2y = 100 - 20

2y = 80

y = 80 / 2

y = 40

From this, we know that the right answer is x = 8, y = 40.

Step-by-step explanation:

To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :

$5.89 + $1.45

Taking the whole numbers first:

$5 + $1 = $6

Take the sum of the decimals :

$0.89 + $0.45 = $1.34

Sum initial whole + whole of sum of decimal

$6 + $1 = $7

Remaining decimal : $1.34 - $1 = $0.34

$7 + $0.34 = $7.34

Step-by-step explanation:

Length of garden = 10-w

Area = (10-w)w = 18.75

w² - 10w + 18.75 = 0

Answer is  [tex]w^{2} - 10w + 18.75 = 0[/tex]

Rectangle Formulas:

Area of the Rectangle (A) = length x breadth.

Perimeter of rectangle (P) = 2 x (length + breadth)

(Given),

A = 18.75square meters

P = 20 meter

Let's length be l and width be w.

P = 2 (l + w)

20 = 2(l + w)

l + w = 10

l = 10 - w    ----( 1 )

Now, A = l x w

18.75 = (10 - w) x w

18.75 = 10w - [tex]w^{2}[/tex]

[tex]w^{2} - 10w + 18.75 = 0[/tex]
