12/49

4*3=12
7*7=49
12/49 miles long is being repaved.

This can be tested by taking a mile (in feet for example) and multiplying 5280 ft by 4/7 then by 3/7 to get the same answer as taking 5280 ft times 12/49.

1/3 cup of flour makes 5 dinner rolls. How many cups of flour for 1 roll? and how much flower for 36 rolls?
shtirl [24]
For one roll, you need to take that 1/3 cup and split it into 5 parts. To do this, divide by 5, which means the fraction becomes 1/15, giving you 1/15 cup flower for one roll.

36 rolls is just 36 times the one roll, which is 36/15 cups. You can divide both parts by 3 to make that 12/5 cups for 36 rolls.

One angle of a parallelogram measures 45°. What are the measures of the other three angles
Sergeu [11.5K]

Answer: 135, 45, and 135 are the three other angles

==================================================

Explanation:

For a parallelogram, we'll have opposite angles with the same measure. So if one angle is 45 degrees, then the opposite angle is also 45 degrees. The other two angles are 180-45 = 135 degrees each. Adjacent angles in a parallelogram add to 180 degrees.

Point b lies on segment AC. find the length of segment BC if AB = 4mm and AC = 4cm
Nataly_w [17]

Answer:

Segment BC = 36 mm or 3.6 cm

Step by Step Explanation:

There are 10 mm in 1 cm

meaning that segment AC is 40 mm long

if AB is 4 mm and it is one part of the two, then we need to subtract that from the total to find out what is left.

40 - 4 = 36

Segment BC = 36 mm or 3.6 cm
