Giving brainliest to first person hurry help!!
Artemon [7]

Answer: If you're looking for the sum of the equation, it's 9.57.

If you're looking for a better way to add it. It's this. (1.7 + 5.3) + 2.57.

Step-by-step explanation: The reason for my answer is quite simple. Since 1.7 and 5.3 add up to 7, all you need to do is add 7 and 2.57. That way, it's much easier to get the answer 9.57

Hope this helped :)

In the diagram below PQR are point on the circle with centre o and diameter 14cm <PRQ=35° Find the length of the minor arc PQ
Gekata [30.6K]

Answer:

Step-by-step explanation:

I'll draw a quick sketch. It's hard to "see" this kinda of problem w/o a drawing , so start there.   just draw as much as you can from what the problem tells you.

diameter = 14 cm

radius = 7 cm

pi = 3.142

PRQ = 35 °

to find Y use law of sines

sin(70) / Y = sin(55) / 7

sin(70) / sin(55) / 7 = Y  ( I'll use my calculator for all the non standard angles )

sin(70) * 7 / sin(55) = Y   ( and invert and multiply the fraction in the denom )

8.03007 = Y

x = 70 °

if you have questions, and  you should, just put them in the comments , I'll see them later :)

Vilka [71]

Answer:

Find the volume of all the fish tanks.

Green fish tank...

4 x 9 x 6 = 216

Brownish fish tank...

4 x 4 x 8 = 128

Orange Fish tank...

6 x 4 x 8 = 192
