Mathematics
1 answer:
Gnesinka [82]3 years ago
7 0

Answer:

a rational number

Step-by-step explanation:

1) First, find the sum of \frac{4}{7} +\frac{-1}{3}:

\frac{4}{7} + \frac{-1}{3} \\= \frac{12}{21} - \frac{7}{21} \\= \frac{5}{21}

2) Any number that can be written as a fraction is a rational number. Therefore, the sum, \frac{5}{21}, is rational.

A box-and-whisker plot shows the distribution of a set of data along with... Quartiles are values that divide a set of data into four equal parts. The second Quartile ( designated Q2) also called the median or the 50th percentile (cuts data set in half ).

Triangle ABC is to be dilated through point P with a scale factor of 3. How many units away from point A along ray PA will A’ be
drek231 [11]

Answer:

A' will be located 10 units from point A along ray PA

Step-by-step explanation:

we know that

The scale factor is equal to 3

To obtain PA', multiply PA by the scale factor

so

PA'=PA*3

PA=5 units

substitute

PA'=(5)*3=15 units

AA'=PA'-PA=15-5=10 units

therefore

A' will be located 10 units from point A along ray PA
