<em>The answer is Ms Hernandez can bring up to 6 people to the zoo.</em>
<em />
<em>x - the number of people that she can bring to the zoo</em>
<em>The parking will cost $7: a = 7</em>
<em>Admission tickets will cost $15.50 per person: b = 15.50x</em>
<em>She can spend on parking and admission tickets $100:</em>
a + b ≤ 100
a = 7
b = 15.50x
7 + 15.50x ≤ 100
15.50x ≤ 100 - 7
15.50x ≤ 93
x ≤ 93 / 15.50
x ≤ 6
5*3 + 5*4
The 5 must multiply through the parenthesis.
Answer:
1) b= 39.5
2) c= 3.6
3) a=19
Step-by-step explanation:
Use the Pythagorean Theorem to find the missing side length.
"C" is the hypotenuse. Pythagorean Theorem: a^2+b^2=c^2
1) 11^2+b^2=c^41
121+b^2=1681
121-121+b^2=1681-121
b^2=1560
b= 39.5
2) 2^2+3^2=c^2
4+9=c^2
13=c^2
c= 3.6
3) a^2+9^2=21^2
a^2+81=441
a^2+81-81=441-81
a^2=360
a=19
Hope this helps!
