Based on this information, who worked at the highest intensity level? Name Target Heart Rate Zone Janna 146bpm—188bpm Shania 145bpm—188bpm Paige 140bpm—182bpm Mimi 140bpm—185bpm A.Janna B Shania C Paige DMimi (02.06 MC)Emma has evaluated her skills and determined that she has many strengths, but power is her least-developed skill. She is signing up for a sport, but she wants to avoid anything that plays to her weakness. Which two sports should she avoid? Gymnastics and soccer Archery and bicycling Swimming and baseball Tennis and volleyball

Gymnastics and soccer since those sports are very active and involve a lot of physical cardio, soccer involves a lot of running.

Swimming and baseball are also some hard sports especially swimming since most are your muscles are used during that activity.

Hope this helps 😉

## BILL CAN HAMMER 20 NAILS IN 6 MINUTES. JEFF CAN DO THE SAME JOB IN ONLY 5 MINUTES. HOW LONG WILL IT TAKE THEM TO FINNISH IF BILL HAMMERS THE FIRST 5 NAILS, THEN JEFF HAMMERS FOR 3 MINUTES, THEN BILL FINISHES THE JOB?

Part A: Coefficients: 85 and 15

Variables: x = shifts at the theater, y = dog-walking jobs

Part B: 2 terms, the first one represents how much he earns working in the theater and the second how much he earns dog-walking. Each term is separated with a sum or a subtract sign.

Part C: 15y

Step-by-step explanation:

Part A: The variable of an expression is the information we don’t know. In this case, we don’t know how many shifts he has at the theater and how many dog-walking jobs he has. That’s why we have 2 variables, x and y. The coefficient is the number that multiplies the variable. In this case, as we have 2 variables, we have 2 coefficients, 85 and 15.

Part B: In an expression, every term is separated with a sum or a subtract sign. In this case, we have just one sum, so the terms are the numbers and variables that appear before and after the sum sign. That’s 85x and 15y. The first one is the amount of money he earns for every shift at the theater multiply by how many shifts he has, so that’s how much he earns in total at the theater. The second one is the amount of money he earns for every dog-walking job multiply by how many he does, so that’s how much he earns in total from the dog-walking jobs.

Part C: As I said in Part B, the second term is the total earned from the dog-walking jobs, so 15y represents it.
