45 feet. 4 x 10 =40 then add the other half an inch to get the total of 45 feet or you could say 9 x 5= 45
Answer:
m∠RMS = 20°
Step-by-step explanation:
Find ∠RMS and look at the two values it crosses.
∠RMS crosses through 180 and 160.
Find the difference between the two values to get the measure:
180 - 160 = 20°
So, m∠RMS = 20°
(Its also an acute angle.)
Check the picture below.
make sure your calculator is in Degree mode.
79,350 cm
Explanation:
115x115=13,225 (this is the area of one side)
13,225x6=79,350(a cube has 6 sides)
Ok so for number 5, AB is proportional to BC just like PQ is proportional to QR. AB = 9, BC = 15, PQ = 3, and QR = x. 9/15 = 3/x. Cross Multiply: This gives you - 9x = 45. Divide both sides by 9, and you get x = 5. QR = 5
