Answer:
Hence, his driving cost of the trip= $ 145.
Step-by-step explanation:
It is given that:
Joshua is planning on 1404 miles driving trip.
His car gets an average of 36 miles per gallon.
i.e. for 36 miles his car uses 1 gallon of gas.
Hence for 1 mile his car uses=1/36 gallon of gas.
Hence, for 1404 miles his car uses=1404/36 gallon of gas
= 39 gallons.
Cos of 1 gallon of gas= $ 3.72
Cost of 39 gallons of gas=$ (3.72×39)=$ 145.08
which is approximately equal to $ 145.
Hence approximately his driving cost of the trip is $145.
Answer:
A
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan12° = 
= 
= 
( multiply both sides by 44 )
44 × tan12° = AC , then
AC ≈ 9.35 ( to 2 dec. places )
Answer:
y=7.51
Step-by-step explanation:
First, you have to simplify one of the equations down
3x-y=4
y=-4+3x
Second, you insert the value of y into the other equation and then solve for x
9x+5(-4+3x)=8
9x-20+15x=8
24x=28
x=1.17
Last, insert the value of x into the original equation and then solve for y
y=4+3(1.17)
y=7.51
Foil:
First term
Outer term
Inner term
Last term
By using foil we just times the first terms together so: x*x=x^2
Then we times the outer terms together so: x*9=9x
Then we times the inner terms together so:7*x=7x
Finally we times the last terms together so: 7*9=63
So our equation is:
X^2+9x+7x+63
Now we collect the like terms
Answer: x^2+16x+63

Answer:
12.04m = l
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 =c^2
where a and b are the legs and c is the hypotenuse
12^2 + 1 ^2 = l^2
144 + 1 = l^2
145 = l^2
Take the square root of each side
sqrt(145) = sqrt(l^2)
12.04159458 = l
To the nearest hundredth
12.04m = l
