QR = 23
Because the triangles are equal to each other, sides QR and TV are also equal. You can create an 3 or 4 step equation by writing the the QR equation is equal to the TV equation and then solving for X. After you solve for X, plug it back into the QR equation to solve for QR.
Answer:
Each equal part is called one-fourth or a quarter of the whole sheet. Thus, any whole can be divided into four equal parts and each part is one-fourth or a quarter of the whole. It is expressed as 1/4 and read as one over four or one upon four.
Step-by-step explanation:
Answer:
Cost of the binder = $5
Cost of the highlighter = $2.5
Cost of the folder = $2
Step-by-step explanation:
Let
Cost of the binder = x
Cost of the highlighter = 1/2x
Cost of the folder = x - 3
Total cost = $9.50
Total cost = Cost of the binder + Cost of the highlighter + Cost of the folder
9.50 = (x) + (1/2x) + (x-3)
9.50 = x + 1/2x + x - 3
9.50 + 3 = x + 1/2x + x
12.50 = 2x + 1/2x
12.50 = 2 1/2x
12.50 = 5/2x
x = 12.50 ÷ 5/2
= 12.50 × 2/5
= 25/5
x = $5
Cost of the binder = x = $5
Cost of the highlighter = 1/2x = 1/2*6 = $2.5
Cost of the folder = x - 3
= 5 - 3 = $2
<u>Answer-</u>
<em>It </em><em>is reasonable</em><em> that the state education department claims the percentage for the entire state is 63%.</em>
<u>Solution-</u>
153 out of the 258 high school students surveyed at a local school said they went outside more during school hours as elementary school students than they do now as high school students.
Here,
x = 153,
n = 258,
Then,
And,
Putting the values,
The interval would be,
As population proportion p=63% lies in this interval, so it is reasonable.
