Answer:
13.19m
Step-by-step explanation:
Divide the total height by the number of step leading
24/91=0.2637 m/step
step 2
Multiply 0.2637 m/step by 50 step
0.2637(50) = 13.19m
Hope this helps!!! :)
So 1 nickle=5 cents
1 quarter=25 sents
q=number of quarters
n=number of nickles so
total is
q+n=20
5n+25q=400 (since 100 cents=1 dollar and 4 dollares=400 cents)
SO THE 2 EQUATIONS WOULD BE
n+q=20
5n+25q=400
so q+n=20
subtract q from both sides
n=20-q
subsitute 20-q for n in the second equation
5(20-q)+25q=400
distribute
100-5q+25q=400
add like terms
100+20q=400
subtract 100 from both sides
20q=300
divide both sides by 20
q=15
thhere are 15 quarters
subsitute 15 for q in first equation
15+n=20
subtract 15 from both sides
n=5
5 nickles
15 quarters

Answer:
59 F
Step-by-step explanation:
F=1.8C+32
Let C = 15
F = 1.8 (15) +32
Multiply 1.8 times 15
F = 27+32
F = 59
15 degrees C is 59 degrees F
