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 unit rate is 20 i think
<h3><u>Question:</u></h3>
A swimming pool measures 35 feet wide by 50 feet long. What is the ratio of the length to the perimeter
<h3><u>Answer:</u></h3>
The ratio of length to perimeter of pool is 5 : 17
<h3><u>Solution:</u></h3>
Given that, swimming pool measures 35 feet wide by 50 feet long
Therefore,
Length = 50 feet
Width = 35 feet
Swimming pool is usually of rectangular shape
<em><u>The perimeter of rectangle is given as:</u></em>
Perimeter = 2(length + width)
Perimeter = 2(50 + 35)
Perimeter = 2(85) = 170
Thus perimeter of pool is 170 feet
<em><u>Ratio of length to perimeter:</u></em>
Thus ratio of length to perimeter of pool is 5 : 17
Well, we can really show our work because their is no work to be done. Question 7 is a right angle because it is exactly 90 degrees. So since you now know what a right angle is, you can probably guess Question 8 a would be either 3 o'clock or 9 o'clock. For question 8b , he first one, and acute angle is an angle where it is below 90 degrees. So an example of an acute time is 3:05. An obtuse angle is an angle above 90 degrees. So an obtuse time would be (for example) 3:55. Hope this helped.
Answer:
Reproduction in Gymnosperms: Gymnosperms are heterosporous and sexual reproduction is oogamous type. In living gymnosperms the reproductive structures are arranged in the form of strobili or cones (except the ovulate structures of Cycas).
