Answer:
-1.2
Step-by-step explanation:
Given that the designer also programs a bird with a path that can be modeled by a quadratic function.
The bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8).
If we treat this curve as line joining these two points then we can find the slope by the formula
Slope = change in y coordinate/change in x coordinate
Here the points given are
(0,20) and (10,8)
Slope of the line that represents the turtle's path
=-1.2
Answer: 0.8

k= 20
a= -0.12
third part is letter B
B. 3 eggs / 2 cups of flour = 12 eggs / 18 cups of flour.
C. 2 eggs / 3 cups of flour = 18 cups of flour / 12 eggs.
D. 3 eggs / 12 cups of flour = 32 eggs / 18 cups of flour.
How much does a bottle of water cost?
How much does a gallon of milk cost?
Answer:
Cost of a snack size bag of chips = $0.8
Cost of a water bottle = $1.6
Cost of a gallon of milk = $3.4
Step-by-step explanation:
Let the cost of water bottle = $a
Cost of 1 gallon milk = $b
and cost of 1 bag of chips = $c
So, cost of 4 gallons of milk, 6 bottles of water and 5 bags of chips = $(4b + 6a + 5c)
4b + 6a + 5c = 27.2 -----(1)
Cost of one water bottle = 2 × cost of one bag of chips
a = 2c -----(2)
A gallon of milk = cost of water bottle + $1.80
b = a + 1.8
From equation (2)
b = 2c + 1.8 -----(3)
Now we substitute these values from equations (2) and (3) in equation (1)
4(2c + 1.8) + 6(2c) + 5c = 27.2
8c + 7.2 + 12c + 5c = 27.2
25c = 27.2 - 7.2
c =
c = $0.8
From equation (2)
a = 2×0.8
a = $1.6
From equation (3)
b = 2(0.8) + 1.8
b = 1.6 + 1.8
b = $3.4
Therefore, cost of a snack size bag of chips = $0.8
Cost of a water bottle = $1.6
Cost of a gallon of milk = $3.4
Answer:
The difference between the size of white blood cells and the size of red blood cells in scientific notation is m.
Step-by-step explanation:
we are given that the size of white blood cells is 0.000012 metres and the size of red blood cells is 0.0000065 metres.
And we have to find the difference between the size of both cells in scientific notation.
SO, Size of White blood cells = 0.000012 m
Size of Red blood cells = 0.0000065 m
Now, Difference between both cell sizes = Size of white blood cells - Size of Red blood cells
= 0.000012 m - 0.0000065 m
= 0.0000055 m
Now, in scientific notation it is represented as = m
Hence, the difference between the size of white blood cells and the size of red blood cells in scientific notation is m.
