The equation for density is:
To help you remember - my teacher told us to remember "We <span>♡ density," and the heart stands for </span>
, or
. Cheesy, but it works!<span>
</span>
Back to the problem:We know the mass if 49g and the volume is 7
, so plug these values into the equation for density:
Answer: The density is 7 g/
<u>Answer:</u>
66 pictures
<u>Step-by-step explanation:</u>
180 ÷ 3 = 60 60 x 2 = 120
120 = 2/3. He took <em><u>120 pictures on the first day </u></em><em><u>of his vacation.</u></em>
120 ÷ 4 = 30 30 x 1 = 30
30 = 1/4. <em><u>He took </u></em><em><u>30 pictures of landscapes</u></em>
120 ÷ 10 = 12 12 x 3 = 36
0.3 = 36. <em><u>He took </u></em><em><u>36 pictures of people.</u></em>
36 + 30 = 66 pictures.
<em><u>He took 66 pictures of landscapes and people.</u></em>

Step-by-step explanation:
do 21×3.14= 65.94
then divide by 2 since its a semicircle
equals: 32.97
than find perimeter altogether
21+28+28+32.97= 109.97ft
Answer:
Step-by-step explanation:
Use identity : (a + b)² =a² + 2ab + b²
49m⁴ + 140m² + 100 = 7²(m²)² + 2 * 7m² * 10 + 10²
= (7m²)² + 2 *7m²*10 + 10²
= (7m² + 10)²
= (7m² + 10)(7m² + 10)
