The Osborne Bakers want to make 30 pounds of a berry mix that costs $3.00 per pound to use in their pancake mix. They are using blueberries that cost $2.00 per pound and blackberries that cost $3.50 per pound. How many pounds of blackberries should be used in this mixture?

Need 50 will mark brainliest answer. find the lengths of all the sides and the measures of the angles.

Can somebody 1. what is the formula for finding the vertical distance between two points on a coordinate plane?

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
