Answer:
t = 4.2 h
Step-by-step explanation:
We can calculate the time taken by the car to travel 400 miles, easily by taking a difference of time in graph between 0 miles and 400 miles value:
t₄₀₀ = 3.5 h - 0 h
t₄₀₀ = 3.5 h
Now, we calculate the constant speed of the car from the following formula:
s = vt
v = s/t
where,
v = velocity of the car = ?
s = distance covered by the car = 400 mi
t = time taken = 3.5 h
Therefore,
v = 400 mi/3.5 h
v = 114.28 mi/h
Now, for this uniform speed the time taken to cover the distance of 480 miles will be:
114.28 mi/h = 480 mi/t
t = (480 mi)/(114.28 mi/h)
t = 4.2 h

the cube of twice a number
Answer:
The cube of twice a number.
Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.

solve for x. 3x+2=38
The value of x by solving for x from 3x +2 = 38 is; 12.
According to the question;
We are required to solve for x from 3x+2=383x+2 = 383x = 38 - 23x = 36x = 12The value of x from the equation is; x = 12

Answer:
A
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle, thus
x = 64° + 45° = 109° → A
Answer:
A
Step-by-step explanation:
64+45=109

How to calculate the area of this?
Answer:
1601 m²Step-by-step explanation:
Split the quadrilateral into 2 triangles as pictured
One of them is right triangle with 2 sides known
The third side is the hypotenuse and is:
√(60²+25²) = √4225 = 65 mTotal area is the sum of the areas of the 2 triangles
A= A1 + A2Area 1
A1 = 1/2*15*60 = 750 m²Use Heron's formula for the second triangle:
A2 = 1/4√(65 + 64 + 27)(-65 + 64 + 27)(65 - 64 + 27)(65 + 64 - 27) ≈ 851m²Total area
A = 750 + 851 = 1601 m²I NEED HELP ASAP PLEASE ANSWER !!!!!!!!!!!
