Alinara [238K]

To solve this you have to first find out how many 1000s are in 14000

There are 14 1000s in 14000 so now you multiply 15.68 by 14

15.68*14=219.52

myrzilka [38]

Answer:

Siw's age is 10 years old

Mona's age is 8 yers old

Mother's age is 40 years old

Step-by-step explanation:

Let

x ----> Siw's age

y ---> Mona's age

z ---> Mother's age

we know that

Siw is a fourth as old as mother

so

x=\frac{1}{4}z ----> equation A

Mona is a fifth as old as mother

so

y=\frac{1}{5}z ----> equation B

Mother is 22 years older than the two girls together.

so

z=x+y+22 ----> equation C

substitute equation A and equation B in equation C

z=\frac{1}{4}z+\frac{1}{5}z+22

solve for z

Multiply by 20 both sides to remove the fraction

20z=5z+4z+440

20z-9z=440\\11z=440\\z=40\ years

Find the value of x

x=\frac{1}{4}(40)=10\ years

Find the value of y

y=\frac{1}{5}(40)=8\ years

therefore

Siw's age is 10 years old

Mona's age is 8 yers old

Mother's age is 40 years old

Write two equations. the first equation should express the area of the square (a as a function of the length (l of a side. the s
Sergeu [11.5K]

Answer:

a = l²

v = s³

Step-by-step explanation:

The area of a rectangle is the product of its length and width. When that rectangle is a square, the length and width are the same. Here, they are given as "l". Then the area of the square is ...

a = l·l = l²

__

The volume of a cuboid is the product of its height and the area of its base. A cube of edge length s has a square base of side length s and a height of s. Then its volume will be ...

v = s·(s²) = s³

The two equations you want are ...

• a = l²

• v = s³
