Please help me with this one

19.1 cm

Step-by-step explanation:

the other side = √8.1²-7.1²=√65.61- 50.41

= √15.20 = 3.9

perimeter = 7.1+8.1+3.9= 19.1 cm

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
