Answer:
128
Step-by-step explanation:
The two angles form a straight line so they add to 180
2m+62 + 3m +143 = 180
Combine like terms
5m+205=180
Subtract 205 from each side
5m+205-205=180-205
5m = -25
Divide by 5
5m/5 = -25/5
m = -5
We want to find the angle so we substitute the value of m into the the formula for the angle.
< RBM =3m +143 = 3(-5) +143 = -15+143 =128
. The number is either 10^1 or 10^3 or 10^ 5 or . . . .
<span>If it is more than 10, then it is not 10^1. The next possibility is 10^3which is 1000, which has factors 2, 5, 10, 20, 25, 40, 50, 80, . . . . . </span>
<span>What constitutes a "multiplication sentence" exactly ? This is not a standard mathematical term. Do you mean "reduce it to its prime factors" ? </span>
<span>1000 = 2 x 2 x 2 x 5 x 5 x 5 </span>
<span>which is a lot more than 4 factors. Or not, if you write it as 2³ x 5³. </span>
<span>But you could say the same about 100 000 = 2^5 x 5^5 </span>
<span>or about 10 000 000 = 2^7 x 5^7 </span>
<span>Take your pick. This is a very badly stated question. </span>
Answer:
30°
Step-by-step explanation:
In m KÔL, the angle is Ô and angle Ô is actually 30 degrees ;)
Answer:
it is on the nearest tenth. The number on the other side of the dot are tenths
Answer:
Circle requires ≈ 20 m of edging
Step-by-step explanation:
A = πR²
R = √(A/π)
C = 2πR = 2π√(A/π)
C = 2π√(30/π) = 19.41625... ≈ 20 m
square needs ≈ 22 m of edging
equilateral triangle needs ≈ 25 m of edging
