50 is the value cause 20 is 40 of the percent, 20+20 is 40 now you made it into 80%.20% is remaining so add 10.

Angle 1 and angle 2 form a linear pair.if m angle =5x+9 and m angle 2=3x+11,find the measures of both angels.

lbvjy [14]

Answer: ∠1 = 109° ∠2 = 71°

Step-by-step explanation:

If the two angles form a linear pair, then their sum is 180°

∠1 + ∠2 = 180°

(5x + 9) + (3x + 11) = 180

8x + 20 = 180

8x = 160

x = 20

∠1 = 5x + 9

= 5(20) + 9

= 100 + 9

= 109

∠2 = 3x + 11

= 3(20) + 11

= 60 + 11

= 71

CHECK:

∠1 + ∠2 = 180°

109° + 71° = 180°

180° = 180° $\checkmark$

Two cell phone companies have different rate plans. Runfast has monthly charges $10 plus $4 per gig of data. B A &D’s monthl

leva [86]

Let x be the number of gb used.

Question (1):
Runfast = 10 + 4x
BA&D= 6 + 6x

Question (2):
 10 + 4x = 6 + 6x
2x = 4
x = 2

Both companies will cost the same if you use 2 Gb of data.
BA&D will be cheaper if you use less than 2 Gb of data.
Runfast will be cheaper if you use more than 2 Gb of data.

A sphere shaped orange has a diameter of 7 centimeters. Find the volume of the orange to the nearest tenth.

krok68 [10]

22cm^3

Step-by-step explanation:

My education system is different so I dont know what nearest tenth would mean in this .

But going mathematically:

Its diameter is 7 centimetres.

So to find its volume we can use the formula pi/d or pi/r^2

Now, 22/7÷7 would be 22cm³.
