Answer:
Jiri is 38 years old.
Step-by-step explanation:
First, 67 - 29 = 38 and 29 + 9 = 38.
Hope this helps!
Answer: D) Reflect over x-axis
=======================================================
Explanation:
When we do this type of reflection, a point like (1,2) moves to (1,-2).
As another example, something like (5,-7) moves to (5,7)
The x coordinate stays the same but the y coordinate flips in sign from positive to negative, or vice versa.
We can say that
as a general way to represent the transformation. Note how y = f(x), so when we make f(x) negative, then we're really making y negative.
If we apply this transformation to every point on f(x), then it will flip the f(x) curve over the horizontal x axis.
There's an example below in the graph. The point A(2,8) moves to B(2,-8) after applying that reflection rule.
Distribute
(x-3)(x+9)=-27
x^2+6x-27=-27
add 27 to both sides
x^2+6x=0
factor out x
x(x+6)=0
set each to zero
x=0
x+6=0
x=-6
x=0 and or -6
x=-6 or 0
The formula for the surface area of a cylinder is pi×2rh+2pi(r^2)
In this problem, r is 4 in and h is 16 in
Answer: SOLUTION -
Let’s convert first the unit dimension of the garden from inches-feet to yards.
HEIGHT: 4 in * (1 ft / 12 in) = 1/3 ft * (1 yard/3 ft) = 1/9 yard
WIDTH: 28 ft * (1 yard/3 ft) = 28/3 yards
LENGTH: 32 ft * (1 yard/3 ft) = 32/3 yards
Then, let’s get the total soil capacity or volume of the garden:
(32/3) * (28/3) * (1/9) = 896/81 = 11.06 cubic yards
Since we can’t buy 0.06 cubic yard of soil, we need to round off 11.06 to the next number of cubic yards that is exactly divisible by 1/4.
It will give us then with 11 & 1/4 cubic yards.
