Answer:
Step-by-step explanation:
Ryan works mowing lawns and babysitting. He earns $8.20 an hour for mowing and $7.70 an hour for babysitting. Therefore, the expression for the total amount that he would earn if he mows lawns for x hours and babysits for y hours would be
8.2x + 7.7y
Therefore, the amount that he would earn for 3 hours of mowing and 7hours of babysitting is
(8.2 × 3) + (7.7 × 7)
= 24.8 + 53.9
= $78.7
Answer:
s=5+3w independent variable is 5+3w. Dependent variable is s, since the total depends on the amount of weeks plus the 5 seashells from the start. s=5+4(3)=17 s=5+5(3)=20 s=5+6(3)=23 s=5+7(3)=26 s=5+8(3)=29 s=5+9(3)=32 s=5+10(3)=35
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
subtract 3 from both sides
then divide by -2/3 from both sides and flip the inequality sign
then you get h > 36/2
Then h > 18
Answer: i know for a fact that one of the options is SAS
Step-by-step explanation:
Using Pythagoras's theorem, we can get that 60 inches is the hypotenuse and 52 inches is one of the legs. 60^2 - 52^2 = b^2, where b is the leg that we are trying to find, aka the length of the shadow. We find that b^2 = 896. The square root of 896 is closest to 30 inches, therefore the answer is A) 30 inches
