To make a scarf, jenny uses blue and white yarn. the number of yards of blue yarn she uses is 4 times the number of white yarn in each scarf. write 4 ratios to show the number of yards of white yarn to blue yarn for a scarf? 7th grade math

 4:1, 8:2, 12:3, 16:4

Step-by-step explanation:

blue is 4 times white  

 blue: white

     4 : 1

multiply both numbers by 2 to get 8:2

multiply both numbers by 3 to get 12:3

multiply both numbers by 4 to get 16:4

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
