——Give —— Lowri kicks a football vertically upwards with a speed of ums-1 from a point which is 0-9m
above horizontal ground. The ball reaches a greatest height of 10.9 m above the ground.
You may assume that there is no air resistance acting on the ball during its motion.
a) Show that u = 14.

Achemist has 200 ml of a 10% sucrose solution. she adds x ml of a 40% sucrose solution. the percent concentration, y, of the final mixture is given by the rational function: the chemist needs the concentration of the final mixture to be 30%. how many milliliters of the 40% solution should she add to the 10% solution to get this concentration?

What is the slope of the equation y =

Yuto and hila attempted to solve the same inequality. their work is shown below. which statement is true about the work shown above? yuto is correct because he isolated the variable correctly and reversed the inequality symbol. yuto is incorrect because he should not have reversed the inequality symbol. hila is correct because she isolated the variable correctly and reversed the inequality symbol. hila is incorrect because she should not have reversed the inequality symbol.
