Determine the greatest common factor of 28xy^9z and 32x^2y^7z

RSB [31]

Answer:

GCF = 4xy⁷z

Step-by-step explanation:

Do Prime Factorizations for each term and select only those terms common to each:

28xy⁹z = 2·2·7·x·y·y·y·y·y·y·y·y·y·z

32x²y⁷z = 2·2·2·2·2·x·x·y·y·y·y·y·y·y·z

GCF = 2·2·x·y·y·y·y·y·y·y·z

GCF = 4xy⁷z

(1 point) All that is left in a packet of candy are 7 reds, 3 greens, and 3 blues.

Sauron [17]

Answer:

A 21 /169

B independent

Step-by-step explanation:

The total number of candies is 7+3+3 = 13

P( 1st red) = red/total = 7/13

Since the candy is put back there are still 13 candies in the dish

P(2nd green) = green/total = 3/13

P( red, then green) = P( 1st red) * P(2nd green)

= 7/13* 3/13 = 21/169

The events are independent since the candies are put back

Allison and Megan were at track practice. The track is 3/8 kilometers around.

Ad libitum [116K]

Allison ran 3/8 km (0.375 km) in 3 minutes.

Set up a proportion to find how long it takes for her to run 1 km

$\frac{0.375\textrm{km}}{3 \textrm{min}} = \frac{1\textrm{km}}{x \textrm{min}}$

Cross multiply to get:

$3 = 0.375x$

Solve:

$x = \frac{3}{0.375}$

x = 8 minutes

Question 12 helllllllppppp plazzzzzzz

Eddi Din [679]

Answer:

Step-by-step explanation:

It says Renita takes minutes to ride half a mile.

She leaves 30 minutes before school.

Total distance is

$2\frac{1}{2} = \frac{1}{2}+ \frac{1}{2} +\frac{1}{2} +\frac{1}{2} +\frac{1}{2}\\$

$2\frac{1}{2} \ there \ are \ 5 \ times \ \frac{1}{2} \ mile .\\$

Therefore total time to reach school will be 5 x 5 = 25minutes.

Since she leaves 30minutes before school. She will reach 5minutes early before school.
