Mathematics
1 answer:
gavmur [86]3 years ago
3 0

Answer:

no

Step-by-step explanation:

30 cents < 10 cents/dime ×  d dimes <  1 dollar × 100 cents/dollar

   if d = 10

30 cents < 10 cents/dime ×  10 dime < 1 dollar × 100 cents/dollar

30 cents < 10 cents/dime ×  10 dime < 1 dollar × 100 cents/dollar

     notice how the units bolded all cancel out, just leaving cents

30 cents < 100 cents  is NOT < 100 cents

The figure below shows a straight line AB intersected by another straight line t:
BaLLatris [955]

When two straight lines intersect, the pairs of nonadjacent angles in opposite posi-tions are known as vertical angles.

If a segment AB is intersected by a transversal labeled t, then ∠1 and ∠3 and ∠2 and ∠4 are vertically angles formed by the transversal t on the segment AB.

Angles ∠1 and ∠2 can be described as adjacent and supplementary angles, so

m\angle 1+m\angle 2=180^{\circ}.

Angles ∠3 and ∠2 can be also described as adjacent and supplementary angles, so

m\angle 3+m\angle 2=180^{\circ}.

Subtract from the first equation the second equation:

m\angle 1+m\angle 2-(m\angle 3+m\angle 2)=180^{\circ}-180^{\circ},\\ m\angle 1-m\angle 3=0,\\ m\angle 1=m\angle 3.

Similarly you can prove that m\angle 2=m\angle 4.

To get an A in a course, you must have an average of at least 90% on four tests worth 100 points each. Your scores so far are 85
kondaur [170]

Answer:

A score of 117 is needed, which Is not possible since the test is over 100.

Step-by-step explanation:

The other 3 scores are 85, 94,84 . Let's x be the 4th score he must score.

Therefore ( 85 + 94 + 84 + X)/4 =95

Then 263+X /4 =95

Cross mutiplying 4*95=263+X

Therefore X= 380-263

X= 117 which is not possible since the test score is over 100.
