Answer:
4.84% of trees on the island are poisonous.
Step-by-step explanation:
The proportion of fruit trees that are poisonous is the number of poisonous fruit trees divided by the total number of trees.
The percentage is the proportion multiplied by 100.
In this question:
60 poisonous trees.
1240 total trees.
60/1240 = 0.0484
0.0484*100 = 4.84%
4.84% of trees on the island are poisonous.
Answer:
a. 3/4 inches per minute
b. -1 1/8 inches per minute
c. B is fastest; 1 1/8 is more than 3/4
Step-by-step explanation:
A <em>change</em> is a <em>difference</em>. A <em>rate of change</em> is <em>one difference divided by another</em>, usually the change in y-value divided by the change in x-value.
__
<h3>a.</h3>
The change in elevation is the difference between the elevation at the end of the period (6 inches) and the elevation at the beginning of the period (3 inches). The change in time period is the difference between the end time (8 min) and the beginning time (4 min).
change in elevation per minute = (6 -3 inches)/(8 -4 min)
= (3 inches)/(4 min) = 3/4 inches/minute
__
<h3>b.</h3>
Similarly, ...
change in elevation per minute = (3 -7 1/2 inches)/(18 -14 min)
= (-4 1/2 inches)/(4 min) = -1 1/8 inches/minute
__
<h3>c.</h3>
We know that 3/4 is more than -1 1/8, but when we talk about the "fastest rate of change", we're generally interested in the magnitude--the value without the sign. That means we understand a rate of change of -1 1/8 inches per minute to be "faster" than a rate of change of 3/4 inches per minute.
The rate of change from Part B is fastest. 1 1/8 inches per minute is more than 3/4 inches per minute.
7 total cups of flour divided by 2.33 cups of flour needed per batch of 24 muffins equals three batches, then multiply total number of batches by number of muffins in each batch- 3x24- gives you a total of 72 muffins

Answer:
Find the perimeter of the quadrilateral with sides 5 cm, 7 cm, 9 cm and 11 cm.
Solution:
The formula to find the perimeter of the quadrilateral = sum of the length of all the four sides.
Here the lengths of all the four sides are 5 cm, 7 cm, 9 cm and 11 cm.
Therefore, perimeter of quadrilateral = 5 cm + 7 cm + 9 cm + 11 cm
= 32 cm
2. The perimeter of the quadrilateral is 50 cm and the lengths of three sides are 9 cm, 13 cm and 17 cm. Find the missing side of the quadrilateral.
Solution:
Let the missing side of the quadrilateral = x
Perimeter of the quadrilateral = 50 cm
