What is the length of the diagonal of a TV that measures 2.25 feet high and 4 feet wide?

NikAS [45]

Answer: Rounded, the diagonal is 4.6 feet

Step-by-step explanation: Use the Pythagorean Theorem: c² = a² + b²

Then take the square root of c² to find the length

2.25² =5.0625 This is a²

4² = 16 This is b² Add a² + b² to get c²

5.o625 + 16 = 21.0625 This is c²

√21.0625 = 4.589389938 This is the square root.

Round this to common measurements or "significant digits" 4.6 feet.

Half of the class likes chips 4th of the class likes pennies and the 7kids left want waterfront how many kids are in the class

S_A_V [24]

There are 28 kids in the class

Step-by-step explanation:

If an object is divided into different part, then

The total of all parts is 1
To find a missing part subtract the sum of the other parts from 1

∵ Half of the class likes chips

- Have means $\frac{1}{2}$

- Assume that the number of kids in the class is x

∴ The number of kids likes the chips = $\frac{1}{2}$ × x =

∵ 4th of the class likes pennies

- 4th means $\frac{1}{4}$

∴ The number of kids likes pennies = $\frac{1}{4}$ x

∵ The rest of the class want waterfront

- Find the rest of the class in terms of x by subtracting the sum

of the two given fractions from the number of kids

∴ The number of kids left = $x-(\frac{1}{2}x+\frac{1}{4}x)$

∵ $\frac{1}{2}x+\frac{1}{4}x=\frac{3}{4}x$

∴ The number of kids left = $x-\frac{3}{4}x$

∴ The number of kids left = $\frac{1}{4}$ x

∵ 7 kids left

- Equate $\frac{1}{4}$ x by 7 and find x

∴ $\frac{1}{4}$ x = 7

Multiply both sides by 4

∴ x = 28

There are 28 kids in the class
