Answer:

13.75

Step-by-step explanation:

First you know there are 5 students and 5 teachers, for each student it costs 6.25 and for every teacher it cost 1.50. So 5 teachers x 1.50= 7.5. 5 students x 1.25 =6.25. 7.5 +6.25= 13.75

On the following number line, two rational numbers are graphed.Represent the two numbers as fractions (or mixed numbers) in lowe
nordsb [41]
The first graphed rational number is at the middle of -2 and -1, thus the number represented is -1 \frac{1}{2}

The second graphed number is five out of six places from from 0 to 1, thus the number graphed is 0+ \frac{5}{6} = \frac{5}{6}

The difference between the two numbers can be represented as
-1 \frac{1}{2} - \frac{5}{6}
or
\frac{5}{6} -(-1 \frac{1}{2} )= \frac{5}{6} +1 \frac{1}{2}

To find the difference,

-1 \frac{1}{2} - \frac{5}{6} \\ \\ =-1 \frac{3+5}{6}  \\  \\ =-1 \frac{8}{6} =-2 \frac{2}{6}  \\  \\ =-2 \frac{1}{3}

Also,

\frac{5}{6} +1 \frac{1}{2} \\  \\ =1 \frac{5+3}{6}  \\  \\ =1 \frac{8}{6} =2 \frac{2}{6}  \\  \\ =2 \frac{1}{6}

2. IQS = 4 and QR is a perpendicular bisector of TS , determined which of the following claims is true
Pavel [41]

Answer:

RS=5 TRUE

RS=4 FALSE (it’s 5)

ST=10 FALSE (it’s 8)

QR=4 FALSE (its 3)

Step-by-step explanation:

First, we have to determine the sides of the triangle.

4x-3=2x+1

4x-2x=1+3

2x=4

x=2

SO, RS=4x-3=4(2)-3=8-3=5

RT=2(x)+1=2(2)+1=5

QR=4²+b²=5².    16+b²=25.    b²=25-16.    b²=9.     b=3

CLAIMS:

RS=5 TRUE

RS=4 FALSE (it’s 5)

ST=10 FALSE (it’s 8)

QR=4 FALSE (its 3)

What are rational numbers
Sophie [7]
A rational number is a number that can be written as a fraction or "ratio".
It includes the set of integers because all of them have a denominator of 1.  A rational number can take on the form of \frac{a}{b} where b ≠ 0.  Terminating and repeating decimals are rational numbers because they too can be written as a ratio; for example, 0.3 = \frac{3}{10} or 0.3333... = \frac{1}{3}.
