jenyasd209 [6]

Answer:

Sentence structure needs to simple, standalone, Grammarly justified and able enough to convey the writer thoughts and feelings clearly

Step-by-step explanation:

Sentence structure is very essential to convey the idea of the writer clearly. It is just like the skeleton of a write up and hence its framework needs to be clear and able enough to express the real sense. The structure of sentence needs to be complete with adequate grammar and punctuations. A good sentence must be able to express a complete idea on its own.

A right triangle has a leg that measures 15 ft and the hypotenuse measures 24 ft. What would the

Serhud [2]

Answer:

x=19

Step-by-step explanation:

First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:

$15^{2} +x^{2}=24^{2}$

Then you square the numbers that you currently have:

$225+x^{2}=576$

Then subtract 225 from both sides to isolate the x:

$x^{2} =576-225$

This gives you the equation:

$x^{2} =351$

Then take the square root of both sides which gives you:

$x=18.7349939952$

Then round to the nearest whole number which gives you x=19

Reuben bought 5CDS that were each the same priceIncluding sales tax, he paid a total of \$81.50. Each CD had a tax of $0.60. wha

Liula [17]

Answer:

The price of each CD before tax is $15.70

Step-by-step explanation:

Given that:

Number of CDs bought by Reuben = 5

Cost of five CDs = $81.50

Sales tax on each CD = $0.60

Sales tax on 5 CDs = 0.60*5 = $3.00

Price of CDs without tax = 81.50 - 3.00 = $78.50

Price of each CD = $\frac{Cost\ of\ CDs}{No.\ of\ CDs}$

Price of each CD = $\frac{78.50}{5}$

Price of each CD = $15.70

Hence,

The price of each CD before sales tax is $15.70
