Supposing all were child tickets:
145x$5=$725
$1153-$725=$428 (diff. between above price and original price)
$9-$5=$4 (diff. between adult price and child price)
$428÷$4=107 (no. of adult tickets)
Ans: 107
Answer:
The population of California is about 5 times the population of south Dakota
Step-by-step explanation:
Let
x ------> the population of California
y -----> the population of south Dakota
we have
x=4,000,000 people
y=800,000 people
Divide the population of California by the population of south Dakota, to find out how many times the population of South Dakota is the population of California
so
x/y
substitute
4,000,000/800,000=5
therefore
The population of California is about 5 times the population of south Dakota
A / B
= 80 / 8
= 10
Therefore the answer is 10
Answer:
Length = 20 inches
Area = 300 inches
Step-by-step explanation:
<em><u>TO FIND THE LENGTH</u></em>
Pythagorean Theorem: 15 squared + x squared = 25 squared
= 225 + x squared = 625
- 225 - 225
= x squared = 400
find square root
= x = 20 inches
x = 20 inches
Length = 20 inches
<u><em>TO FIND THE AREA</em></u>
length x width
length = 20 inches
width = 15 inches
20 x 15 = 300
Area = 300 inches
Answer:
Q1) D
Q2) C
Step-by-step explanation:
Q1)
y ∝ x
y = kx
Let x=-1,y=2
2 = k(-1)
k = -2
Q2)
directly (y=kx)
Let x=2,y=4
4 = k(2)
k = 2
y = 2x
inverse (y = k/x)
Let x=2,y = 4
4 = k/2
k = 8
xy = 8
