Answer:

  • 63°
  • 50° , 40°

Step-by-step explanation:

1.

3 :7 \\Acute \: angle = 90\°\\7+3 = 10\\\frac{7}{10} \times 90\\\\= \frac{630}{10}\\ = 63 \°\\

2.

Let \:the\: other\:acute \:angle\: be \:x\\According\:to \:the \:question ; \\ \:\\(2x-30)+x =90\\2x - 30 +x =90\\2x +x = 90+30\\3x = 120\\\frac{3x}{3} =\frac{120}{3} \\x = 40 \\\\(2x -30)\\2(40) -30\\80 - 30 = 50\\\\\\Angle \:1 = 50\°\\Angle \: 2 = 40\°\\

Which of the models show 1.28 ÷ 4?
Talja [164]

Answer:

1.28 ÷ 4 = 0.32

But the "models" make little or no sense.  I can see the three bars and two dots representing the digits 3 and 2, but that is the only image I see, repeated three times.  It also shows no reference to the decimal place, so I would say there is no real representation of it all.

A box of small crackers holds 4 equal servings. If there are 124 crackers in the box, how many crackers are in each serving?
kotykmax [81]

For this equation, we can simply divide the box's total (124) by 4 servings. 124/4 = 31. So, there is 31 crackers per serving.
