Answer:1234
Step-by-step explanation:123456
The slope m of a straight line passing through points (x₁,x₂) and (y₁,y₂) can be calculated like this:
m = change in y-value / change in x-value
m = (y₂ - y₁) / (x₂ - x₁)
We are given the points as (7,r) and (4,6) and slope m=0 . Substituting these:
⇒m = 6 - r / 4 - 7
⇒0 = 6 - r / -3
∴ r = 6
Irrational number because it cannot be expressed as a fraction of two whole numbers and it has no accurate decimal equivalent.
So its Irrational hope this helped :)
Answer:
yes it is irrational

Answer:
Surface Area of the juice box = 269.6 cm²
Step-by-step explanation:
The dimensions of the box in shape of rectangular prism is given by :
6.4 cm × 4 cm × 10.5 cm
⇒ Length = 6.4 cm
Width = 4 cm
Height = 10.5 cm
Surface Area of rectangular prism is given by the formula = 2(wl + hl + hw) ,where w = width, h = height and l = length
⇒ Area of rectangular prism shaped box = 2(4×6.4 + 10.5×6.4 + 10.5×4)
= 2(25.6 + 67.2 + 42)
= 2 × 134.8
= 269.6 square cm
Hence, Surface Area of the juice box = 269.6 cm²
Therefore, The correct option is D. 269.6

Answer: There are 165 boys
Step-by-step explanation:
Let's call b the number of boys and call g the number of girls in the class.
Then we know that:
There are 462 students. This is:
We also know that there are 132 more girls than boys, this means that:
Now we substitute the second equation in the first and solve for b.
