6 0

Answer:

2/5 or 0.4

Step-by-step explanation:

Let the number be x

75% of x = 30%

\frac{75}{100}*x=\frac{30}{100}\\\\x =\frac{30}{100}*\frac{100}{75}\\\\x=\frac{30}{75}\\\\x=\frac{2}{5}

The diagonal of a rectangular swimming pool measures 29 yards. If the length of the pool is 25 yards, which measurement is close
nirvana33 [79]

Answer:

Width of the pool = 15 yards

Step-by-step explanation:

Given that:

Length of diagonal of swimming pool = 29 yards

Length of the pool = 25 yards

Let,

w be the width.

This will form a right angled triangle where the diagonal will be hypotenuse.

Using Pythagorean theorem;

(25)^2+(w)^2 = (29)^2\\625+w^2=841\\w^2= 841 - 625\\w^2 = 216

Taking square root on both sides

\sqrt{w^2}=\sqrt{216}\\w=14.70

Rounding off to nearest whole number

w = 15 yards

Hence,

Width of the pool = 15 yards

What is x when 2(x+3)=x-4
denpristay [2]

Answer:

x=-10

Step-by-step explanation:

First, use distribution to simplify

2(x+3)=x-4\\2x+6=x-4

Then, simplify further by combining like terms

2x+6=x-4\\2x+10=x\\10=-1x

Solve

10=-1x\\x=-10\\
