Answer:

Step-by-step explanation:

Step 1: Obtain zero on one side and then factor. Step 2: Set each factor equal to zero. Step 3: Solve each of the resulting equations. This technique requires the zero factor property to work so make sure the quadratic is set equal to zero before factoring in step 1.

Imelda rode her bicycle 39 kilometers. If 1 meter = 1.094 yards, find the distance Imelda rode her bicycle to the nearest mile.

Alborosie

Answer: 24.24 miles

Step-by-step explanation:

We should note that 1000 metres = 1 kilometer.

Imelda rode her bicycle 39 kilometers which will be converted to meters a:

= 39 × 1000

= 39000 meters

Since 1 meter = 1.094 yards

39000 meters = 39000 × 1.094 = 42666 yards

To find find the distance Imelda rode her bicycle to the nearest mile goes thus:

1 mi = 1760 yd

42666 yards will be converted to miles. This will be: 42666/1760 = 24.24 miles

A corner of a rectangle is cut, creating a trapezoid.

forsale [732]

Answer:

the last option of 135°.

Step-by-step explanation:

The total degree of the rectangle is 360°. But it was sliced, so with the remaining measurements, subtract each of them from 360°.

90°+90°+45°+x°=360°

225°+x°=360° add all of the values on the left side, then subtract 225 on both sides to solve for the value of x°.

x°=135°
