Assuming that 2 people who will repair a refrigerator equally fast will do it twice as fast when working together: Jannete repairs 1/60 refrigerator per minute. Lisa repairs 1/40 refrigerator per minute. Togheter they repair 1/60+1/40= 1/60 + 1,5/60 = 2,5/60=5/120=1/24 refrigerator per minute thus it will take them 24 minutes

If they are working together well it already takes jannette 60 minutes and liza is 20 minutes faster since Liza is the faster one you would use her time and that would be 60 - 20 = 40 so B

Answer:

m∡A = 14

m∡B = 76

Step-by-step explanation:

Two Angles are Complementary when they add up to 90 degrees.

So 3x -7 + 11x - 1 = 90, which we can solve.

14x - 8 = 90

14x = 98

x = 98/14 = 7

with the knowledge of x=7, we can find the angles:

m∡A = 3·7 - 7 = 14

m∡B = 11·7 - 1 = 76

Supplementary angles are angles that add up to 180 degrees, so the next assignment is very comparable, try it!

${( {2}^{8} \times {3}^{ - 5} \times {6}^{0} })^{ - 2} \\ = \frac{1}{ {( {2}^{8} \times {3}^{ - 5} \times {6}^{0} })^{2} } \\ = \frac{1}{ {(256 \times \frac{1}{ {3}^{5} } \times 1 })^{2} } \\ = \frac{1}{ {(256 \times \frac{1}{243} \times 1 })^{2} } \\ = \frac{1}{ ({ \frac{256}{243} })^{2} } \\ = \frac{1}{ \frac{ {256}^{2} }{ {243}^{2} } } \\ = \frac{1}{ \frac{65536}{59049} } \\ = \frac{59049}{65536}$
The answer is 59049/65539
The value is 0.901

2x <10 or x\2 >3 someone knows what does x equal

DaniilM [7]

Step-by-step explanation:

For the first one,

2x < 10

Divide both sides of the inequality by 2,

2x ÷ 2 < 10 ÷ 2

x < 5

Now, for the second one,

x/2 > 3

Multiply both sides of the inequality by 2,

x/2 × 2 > 3 × 2

this will cancel the fraction and will give us,

x > 6

That's it! I hope this explanation was useful enough ;)
