Answer:
B. 22
Step-by-step explanation:
124.06 = 2.35h + 72.36
124.06 - 72.36 = 2.35h
51.7 = 2.35h
51.7/2.35 = h
22 = h
You have to do Pythagorean theorem:
"a" and "b" are the legs. In this case 7 is a leg and x is a leg
"c" is the hypotenuses, which is 19 here
so...
a = 7
b = x
c = 19
Plug the numbers above into the equation:
Isolate x by subtracting 49 to both sides:
To solve for x you have to take the square root to both sides of the equation:
x = 17.6635
x = 17.7
Hope this helped!
You would need to do 2.069+73% which would get you 3.57937
Answer:
75:125=3:5
Step-by-step explanation:
1. Add the total number of parts
3+5=8
2. Find out how much one part is
200/8=25
3. Multiply each ratio by 25
3*25=75
5*25=125
4. Check they add up to 200
75+125=200
x equals 4 and y equals 5 . so the formula would be 5x+12y=80 and if we need 4 of the small boxes we sub x for 4 and we get 5(4) =20. Next, 80 minus 20 is 60, and the equation would now be 12y=60. we now divide both sides by 12 and we get left with y=5. 5x + 12y = 80 5(4) + 12(5)=80 20+60=80. That is all. I hope that doesn't sound confusing
