Answers
A. 18 ft in 20 minutes
B. 90 feet in 150 minutes
C. 60 feet in 90 minutes
D. 11 feet in 15 minutes
18/20 = .9
90/150 = .6
60/90 = 2/3
11/15 = 7.33333
A is the fastest
Answer:
Speed = Distance/time in km/h
a) 18 feet in 20 minutes
0.0054864 km/0.333333hours
=0.01645921645 km/h
b) 90 feet in 2.5 hours
0.027432km/2.5
=0.0109728 km/h
c) 20 yards in 1.5 hours
0.018288km/1.5
=0.012192 km/h
d) 3 2/3 yards in 15 minutes
0.003352800000003048km/0.25hours
=0.0134112
So I think its safe to say that A is the fastest in comparison

Solve each equation with the quadratic formula. (Show work please)
Answers
Answer:
Let b=x
Such that b^2 =8b-8 will x^2=8x-8
Using the almighty quadratic formula
x1={-b+sqrt (b^2-4ac)}/2a
x2={-b-sqrt (b^2-4ac)}/2a
From the question
a=1
b=8
c=-8
x1={-8+sqrt (8^2-4(-8))}/2
x1=(-8+5.66)/2
x1=-1.17
x2={-8-sqrt (8^2-4(-8))}/2
x2=(-8-5.66)/2
x2=-6.83

Your factory installed tires have a comfort that 95 inches if the odometer reading reading is 32,000 miles on your car you have tires with a conference have 103 inches how many miles have you actually traveled
Answers
Answer:
The correct solution is "35440.8".
Step-by-step explanation:
The given values are:
Bigger tire's circumference,
= 103 inches
Factor installed tire's circumference,
= 95 inches
Odometer reading,
= 32,000 miles
As we know,
⇒ [tex]Actual \ distance = K\times odometer \ reading[/tex]
Where,
⇒ [tex]K = \frac{Bigger \ tier \ circumference}{Factor \ installed \ tier \ circumference}[/tex]
i.e.,
⇒ [tex]K=\frac{103}{95}[/tex]
On applying the formula,
⇒ [tex]Actual \ distance \ travelled=\frac{103}{93}\times 32,000[/tex]
⇒ [tex]=35440.8[/tex]

Answer:
the missing side is √65
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 7^2 = c^2
16 + 49 = c^2
65 = c^2
√65 = √c^2
√65 = c
4 squared = 2 squared + c
16= 4+ c
c squared =12
c=3.464
now that you’ve found c , u have to move on to the bigger triangle
a squared= 7 squared + 3.464 squared
a squared= 49+ 12

Composition of functions~
Answers
Answer:
[tex]g(h(-8)) = 119[/tex]
Hence, option B) is true.
Step-by-step explanation:
Given
g(x) = 2x-5
h(x) = x² - 2
To determine
[tex]g(h(-8)) = ?[/tex]
In order to determine g(h(-8)), first we need to determine h(-8), so
substituting x = -8 in h(x) = x² - 2
h(x) = x² - 2
h(-8) = (-8)² - 2
h(-8) = 64 - 2
h(-8) = 62
so we can write
[tex]g(h(-8)) = g(62)[/tex]
now, to determine g(62), substitute x = 62 in g(x) = 2x-5v
g(x) = 2x-5
g(62) = 2(62) - 5
g(62) = 124 - 5
g(62) = 119
so,
[tex]g(h(-8)) = g(62)=119[/tex]
Therefore,
[tex]g(h(-8)) = 119[/tex]
Hence, option B) is true.
