Dalton's Desserts made a batch of fresh scones with 9/10 of a pound of butter and 1/5 of a pound of sugar. How much more butter than sugar was used?

= 7/10

Step-by-step explanation:

butter = 9/10

sugar = 1/5 = 2/10

butter - sugar = 9/10 - 2/10 = 7/10 = 0.7 = 70%

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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
