Help me with this problem? GIVING BRAINLIEST!!
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

A triangle with sides of 14 15 and 29 does it form a right triangle 
Answer: No.
Step-by-step explanation: This triangle does not form a right triangle because it does not have a 90 degree angle.
Answer:
No
Step-by-step explanation:
Use Pythagorean Theorem: (a^2 + b^2 = c^2)
a^2 + b^2
(14)^2 + (15)^2
196 + 225 = 421
Now for c:
29^2 = 841
841 does not 421 so its not a right triangle

Car Survey In a survey of 1,300 people who owned a certain type of car, 910 said they would buy
that type of car again. What percent of the people surveyed were satisfied with the car?
% of the people surveyed were satisfied with the car.
Answer: let
Total number of those who took part in the survey (T) = 1300
Those were satisfied with the car(t)=910
Percentage of those who are satisfied (S)= (t/T)*100
S=(910/1300)*100
S=70%
Therefore 70% were satisfied

Composition of functions~
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.
please help me! ( pythagorean theorem)
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

Solve each equation with the quadratic formula. (Show work please)
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
:.(x1,x2)=(-1.17,-6.83)
Step-by-step explanation:
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
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]
