lauren planted 20 flowers, but her neighbors dog ate 7 of them. what percent of the flowers did the dog eat

LuckyWell [14K]

35 percent got eaten.

To solve: you’d take the number of flowers eaten, 7. And you’d divide it by the overall number, 20. Then you’d get 0.35, which would be your percent.

∠QPS is a right angle and m∠QPR = 71°, what is m∠RPS?

natta225 [31]

Answer: <RPS = 161

Step-by-step explanation:

P is the common vertex in all of these angles. From this we know that these have to be adjacent angles (<QPR and <QPS) that equal the whole angle (<RPS)

<QPR+<QPS= <RPS

71+90= 161

(<QPS is a right angle. Right angles are equal to 90 degrees.)
