Answer:
311.6 cm
Step-by-step explanation:
To solve this problem, let's call:
k = Keith's height
n = nephew's height
Since the ratio is 15:7, we have
(1)
Then, Keith's height is increased by 16%, so the new height of Keith is
(2)
While the nephew's height is doubled:
(3)
We also know that Keith is now 34 cm taller than his nephew, so
(4)
Substituting (2) and (3) into (4), we get
And substituting (1),
Solving for n,
So the current height of the nephew is:
While Keith's current height is
So their total current height is
The answer is rounded to the nearest tenth.
The new coordinates of the dilated polygon would have coordinates at M'(1.6, 3.2) and N'(3.2, 4).
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Dilation is the increase or decrease in the size of a figure by a scale factor.
Given that Polygon MNOPQ is dilated by a scale factor of 0.8 with the origin. If point M(2, 4) and N(4, 5). The new coordinates would be at M'(1.6, 3.2) and N'(3.2, 4).
The new coordinates of the dilated polygon would have coordinates at M'(1.6, 3.2) and N'(3.2, 4).
