How do you simplify: 2 radical 50- 3 radical 8

Mathematics

3 0
Let A = <span>2 radical 50- 3 radical 8 
</span> radical 50 = sqrt( 2* 25 ) = 5sqrt( 2 )
 radical 8  = sqrt(2*4) = 2 sqrt(2)
so 
A = 2 radical 50- 3 radical 8 = 10sqrt( 2 ) - 6sqrt( 2 ) = 4sqrt( 2 )
finally 

A = 4sqrt( 2 )

Answer:

1. The height is 9 feet

2. The height will increase. The new height is 15

3. The total cost will be $1,875

Step-by-step explanation:

15² = (24÷2)² + h²

Step 1: Simplify both sides of the equation.

225=h²+144

Step 2: Subtract h^2 from both sides.

225−h²=h²+144−h²

−h²+225=144

Step 3: Subtract 225 from both sides.

−h²+225−225=144−225

−h²=−81

Step 4: Divide both sides by -1.

−h²/-1 = −81/-1

h² = 81

Step 5: Take square root.

√h² = √81

h = 9

2. 18² = 10² + h²

Step 1: Simplify both sides of the equation.

324=h²+100

Step 2: Subtract h^2 from both sides.

324−h²=h²+100−h²

−h²+324=100

Step 3: Subtract 324 from both sides.

−h²+324−324=100−324

−h²=−224

Step 4: Divide both sides by -1

−h²/-1 = −224/-1

h² = 224

Step 5: Take square root

√h² = √224

h = 14.96663

round the number to the nearest whole number

h = 15

3. Find the area of the of the material. (length × height) ÷ 2

length = 20feet

height = 15feet

20 × 15 ÷ 2

300 ÷ 2

150

Area = 150feet

Since the sun shade costs 12.50 per square foot, and the sun shade is 150feet, we must multiply them

12.50 × 150 = 1,875

Aldo made a shirt using 1/5 meters of yellow fabric and 2/3 meters of red fabric. How many meters of fabric did he use in all? W
fgiga [73]

Answer:

\frac{13}{15} m of fabric

Step-by-step explanation:

To solve this problem, we add the meters of yellow fabric Aldo used with the meters of red fabric he used.

\frac{1}{5}+\frac{2}{3}

However, we have to find a common denominator between the two fractions first in order to add them together. We can do this by multiplying the numerator and denominator in 1/5 by 3, and then multiplying the numerator and denominator in 2/3 by 5.

Essentially, we're multiplying the values in each fraction by the other fraction's denominator.

\frac{1}{5} ⇒ x3 ⇒ \frac{3}{15}

\frac{2}{3} ⇒ x5 ⇒ \frac{10}{15}

Now, we add the two fractions.

\frac{3}{15} + \frac{10}{15}\\=\frac{13}{15}

I hope this helps!
