Answer:
-5/7
Step-by-step explanation:
When you divide fractions, you flip the second fraction, then multiply.
So it becomes -25/28 x 4/5.
This equals -100/140 which reduces to -5/7.

Answer:
- arc BC: 8.55 cm
- chord BC: 8.03 cm
Step-by-step explanation:
The length of an arc that subtends central angle α will be ...
s = rα . . . . where α is in radians
The central angle BOC is twice the measure of angle QBC, so is 70°, or 7π/18 radians. So, the length of arc BC is ...
s = (7 cm)(7π/18) ≈ 8.55 cm . . . arc BC
__
For central angle α and radius r, the chord subtending the arc is ...
c = 2r·sin(α/2)
c = 2(7 cm)sin(35°) ≈ 8.03 cm . . . . chord AB
Answer:
Answer is A(-3/4, 1/4), B(1,3/4), C(1/2,3/4) D(1/4,1)
Step-by-step explanation:
From the attached diagram, the coordinates are:
A(-3,1), B(4,-3), C(2,3), D(1,4)
The image is gotten by dividing the coordinates by the scale factor 4 to get the above answer
Divide 108 and 72 by twelve and you get 9 and 6 which all you have to do it multiply together
