Question

Ten years ago, Melissa planted a tree in
her backyard. She has taken a photo of
the tree every week so she can see how
it has grown as time passed. How many
photos of the tree does Melissa now have?​

Answer 1

Answer:

The number of photos is equal to 520

Step-by-step explanation:

Remember that

$1\ year=52\ weeks$

To convert years to weeks multiply by 52

we know that

The number of photos is equal to the number of weeks in 10 years

so

$10\ years=10(52)=520\ weeks$

therefore

The number of photos is equal to 520

Answer 2

Answer:

100 m

Step-by-step explanation:

The tree's first measurement = 15 centimeters

The tree's measurement after a week =25 centimeters

The difference in growth = 25 - 15 = 10 cm

Since we are asked to find out how many millimeters the tree grew, we convert our result to millimeters.

Conversion Unit: 1 centimeter = 10 Millimeters

Therefore: 10 cm = 10 X 10 =100 Millimeters

The tree grew 100 Millimeters in a week.
