Answer:
Answer: 9
Step-by-step explanation:
• For f(0), substitute x with zero:
If you divide how many total seconds she got off in each game by its penalty, you will see this:
-35 - (-7) = 5
-25 - (-5) = 5
35 divided by 7 is 5, and 25 divided by 5 is 5.
The amount of penalties Yolanda received is equal.
Answer:
Number of students van can carry = 11
Number of students bus can carry = 41
Step-by-step explanation:
Given the following :
HIGH SCHOOL A:
Number of students = 184
Number of vans(v) = 13
Number of buses(b) = 1
Mathematically,
13v + 1b = 184 - - - - (1)
HIGH SCHOOL B:
Number of students = 520
Number of vans(v) = 10
Number of buses(b) = 10
Mathematically,
10v + 10b = 520 - - - - (2)
Multiply (1) by 10 and (2) by 1
130v + 10b = 1840 - - - (3)
10v + 10b = 520 - - - (4)
Subtract (4) from (3)
120v = 1320
v = 11
Substitute v = 11 into (1)
13(11) + 1b = 184
143 + b = 184
b = 184 - 143
b = 41
Number of students van can carry = 11
Number of students bus can carry = 41
multiply by 4 for each number
5*4=20
20*4= 80
80*4=320
Answer is 320
Hi,
BC²=CA²-BA²=13-9=4=2² (Pythagore)
CB/ED=AB/AD (Thalès)
2/2.5=3/AD==>AD=3*2.5/2=7.5/2
DB=DA-AB=7.5/2-3=0.75
I don't know how you call this 2 theorems (sorry)
