Answer: The change in height is 30 1/4 feet.
Solution:
Change in height: h=?
The car starts by going up 80 and one half feet:
h=+80 1/2 feet
Then the car goes down 50 and one fourth feet:
h=80 1/2 feet - 50 1/4 feet
h=80 2/4 feet - 50 1/4 feet
h= 80-50 2/4-1/4 feet
h=30 (2-1)/4 feet
h=30 1/4 feet
Answer:
It's a
Step-by-step explanation:
This is a quadratic expression with the highest power of X being 2.
The coefficient of X² = 1
Note that the general form of a quadratic equation is aX² + bX + C
In this question,
a = 1
b = 7
C = 10
First step is to multiply a and C ( a x C)
= 1 X 10 = 10
Then, find 2 factors of 10 which can both add up to give 7, the coefficient of X given in the question.
The possible factors of 10 are 5 and 2. The sum of 5 and 2 is
5 + 2
Hence, the equation can be written as;
X² + 7X + 10 = X² + 5X + 2X + 10
The next step is to group using a bracket and factorise each bracket individually
(X² + 5X) + (2X + 10) =
X( X + 5) + 2( X + 5) =
(X + 5) (X + 2)
(X + 5) (X + 2) are the factors of the quadratic equation, X² + 7X + 10
Answer:
342.30
Step-by-step explanation:
342.296 would round up because 6 is higher than five. The 0.09 would round up to 0.10, making the 0.2 become a 0.3.
You can add the length of the sides to find the perimeter.
8 + 8 + 7 + 12 = 35 inches
