Sorry, why didn't I answer this sooner?
Answer:

114 units^2

Step-by-step explanation:

I know I know it's a bit weird and childish answer, but it works, really, all you have to do given the dotted line is:

2*12=24

15*12=180

180/2, since it's not a rectangle, but half of it, think of it like a rectangular sandwich. Cut it in half diagonally and it's still half.

180/2=90

90+24=

114

Consider Akelia’s sequence 5, 8, 11, 14, 17, ….

bonufazy [111]

Answer:

It would be 20

Step-by-step explanation:

As we can see, the sequence starts from 5 and increases by three each time. In fact, one possible formula for that sequence could be:

$a_n=3n+2\hspace{10}n\in N$

Let's confirm the formula by evaluating the first 6 terms:

$a_1=3(1)+2=3+2=5\\a_2=3(2)+2=6+2=8\\a_3=3(3)+2=9+2=11\\a_4=3(4)+2=12+2=14\\a_5=3(5)+2=15+2=17\\a_6=3(6)+2=18+2=20$

Hi pls help.you do not have to do all 3. just either one will be ok pls explain as well:) thank you

noname [10]

Answer:

${7a^{5}b^{5} c\\$

Step-by-step explanation:

$\frac{28a^{8}b^{6} c^{3} }{4a^{3}bc^{2} }$

→ First look at the first term of each expression and see if they can be simplified, and they can

$\frac{7a^{8}b^{6} c^{3} }{a^{3}bc^{2} }$

→ Now look at the a terms, since a larger one is at the top, you subtract

$\frac{7a^{5}b^{6} c^{3} }{bc^{2} }$

→ Now simplify the b and c terms

${7a^{5}b^{5} c$

Find the pressure exerted by a force of 240 N on an area of 30 cm2. Find the answer in SI unit

NeTakaya

Answer:

Pressure is 80,000 pascals.

Step-by-step explanation:

Area:

$= { \bf{ 30 \times {10}^{ - 4} \: {m}^{2} }}$

Pressure:

${ \bf{pressure = \frac{force}{area} }} \\ \\ { \tt{ = \frac{240}{30 \times {10}^{ - 4} } }} \\ = { \tt{80000 \: pascals}}$

Aly's science class was looking at bacteria through a microscope. Aly's teacher said some bacteria can be as small as 0.00365 cm

Thepotemich [5.8K]

Answer:

The answer is 3.65 x 10^3 power.

Step-by-step explanation:

In scientific notation, you need only the one's place, so 36.5 would not work. I hope this helps, I know this is a day late and you probably figured it out, but just in case you didn't, here is the answer :)
