false becasue 11,12,13,14,15,16,17,18,19,20,21, and 22 is bigger and 111,112,113,114,115,116,117,118,119,120,121, and 122 is smaller.
#2 is 35°C (just plug in 95 to the formula)
#3:
in the left column are:
(8x-(6+y))
(3/4)w+x^2
in the right column are:
y^2-0.5w
w/4+3(x+y)
to solve you just plug in to the formula
Answer:
x=7
7-7/7-6=0
0/1=0
Zero divided by anything=0
Answer:
89·98 mph
Step-by-step explanation:
First, we get the circumference of the tires:
Circumference =
× (radius × 2)
Circumference = 3.142 × (1·5 × 2)
Circumference = 3·142 × 3
Circumference = 9·426 ft
The circumference of the tire is equal to one round.
1 round = 9·426 ft
840 rounds = ?
We cross multiply to get the length that the tires would cover in a minute
= <u>840 × 9·426</u>
1
1 minute = 7917·84 ft
60 minutes = ?
<u>60 × 7917·84</u>
1
= 475070·4 ft
5280 feet = 1 mile
475070·4 feet = ?
<u>475070·4 × 1</u>
5280
475070·4 ÷ 5280 = speed of the car in mph
89·97545
Round this off to 2 decimal places...
= 89·98 mph
hope this helps! =)
z=3. If z varies inversely as w, and z=4 when w=9, then when w=12 the value of z is 3.
The key to solve this problem is using reverse proportionality, in which two magnitudes a and b are inversely proportional when there is a constant k such that
a⋅b=k, where constant k is called the proportionality constant.
Then if z varies inversely as w, and z=4 when w=9
z.w=k -------> 4.9=k -------> k=36
So, let's find z when w = 12. With k = 36
z.w=K, clear z from the equation
z=k/w -------> z=36/12 -----> z=3
