Step-by-step explanation:
vamsi is X years old.his brother is 3 years elder to him. his uncle is 4 times his age and his aunt is 5 years younger than his uncle.what are the ages of vamis brother, uncle and aunt? what will be the age of his uncle 6 years from now
pls send the ans fast
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

a polygon has 50 sides
all but one of its angle is 170 degrees
what is the size of the other angle?
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.
What are polynomials?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.

In a class of 30 pupils the ratio of the number of boys to the number of girls is 7 : 8. How many girls are there?
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

what is the value of x and y?
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.

Olivia has a 20 meter-long fence that she plans to use to enclose a rectangular garden of width w. The fencing will be placed around all four sides of the garden so that its area is 18.75 square meters. Write an equation in terms of w that models that situation.
Answer:
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]

A group of friends wants to go to the amusement park. They have $243.25 to spend on parking and admission. Parking is $15.75, and tickets cost $22.75 per person, including tax. How many people can go to the amusement park?
Answer: 10 people
Step-by-step explanation:
Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.
The amount spent on just tickets is therefore:
= 243.25 - 15.75
= $227.50.
If $227.50 was for tickets alone, the number of tickets they could buy is:
= Total amount left/ Price of tickets
= 227.50 / 22.75
= 10 people
