Long-billed curlews eat many different kinds of insects, including grasshoppers, as a source of food. It has been shown that pesticide use kills many of these insects. How would you expect an increase in pesticide use to affect to the population of long-billed curlews in the same area
An increase in the use of pesticides in the same area would lead to the population of long - billed curlews decreasing.
How will the population of long-billed curlews be affected by pesticides ?An increase in pesticide use that kills many of the insects that long-billed curlews eat, such as grasshoppers, would likely have a negative impact on the population of long-billed curlews in the same area.
Since grasshoppers and other insects are a primary food source for long-billed curlews, a decline in insect populations due to pesticide use could lead to reduced food availability and increased competition for remaining food sources. This could lead to decreased population size and potentially even local extinctions.

A road is 4350m long, correct to the nearest 10 metres. Kirsty drove along the road in 205 seconds, correct to the nearest 5 seconds.
The average speed limit for the road is 80km/h
Could kirsty’s average speed have been greater than 80km/h?
Kirsty's Average speed is not greater than 80km/h
What is speed?Speed is the rate of change of distance.
Analysis:
length of road = 4350m = 4350/1000km = 435/100km
time taken = 205 seconds = 205/3600 hour
Her Speed = 435/100 ÷ 205/3600 = 435/100 x 3600/205 = 76.4km/h
In conclusion, Kirsty's average speed is not greater than 80km/h.

does anyone know what the questions are for module 3 algebra dba
Answer:
no
Step-by-step explanation:
I never knew u had dba for math
I need help on this question I don’t get what it’s asking what so ever
Answer:
y=4
Step-by-step explanation:
The question is asking what is the value of y:
Since all lengths have a dash on them they are all equal :
So 3y = y+8
3y = y + 8
First we subtract y from both sides:
3y-y = y+8-y
2y = 8
Divide both sides by 2:
2y÷2 = 8÷2
y = 4
Answer:
Step-by-step explanation:
The question is asking you to find the value of y in a square.
A square has same length in all sides so we can achieve that:
y+8 is equal to 3y
simplifying that, we find out the answer is 4. How?
We have previously acheived that:
y+8=3*y
So we need to find y using these steps:
1. Subtract 3y from both sides:
y+8−3y=3y−3y
−2y+8=0
2. Divide both sides by -2:
y=4

The measure of the vertex angle is
degrees.
Answer:
x = 50
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
Since triangle ABC is an isosceles triangle the measure of <c is also = x
x + x + x + 30 = 180 add like terms
3x + 30 = 180 subtract 30 from both sides
3x = 150 divide both sides by 3
x = 50

Kalyue drew a rectangle with a perimeter of 20 inches. Then he tried to draw a square with a perimeter of 20 inches. What are the dimensions of square with a perimeter of 20 inches?
Step-by-step explanation:
a square has 4 identical sides.
so, when you have to "walk" around the perimeter of a square you have to go 4 times the same distance.
therefore
20 = 4×side length
side length = 20/4 = 5 in
it is a 5 in × 5 in square.
FYI a rectangle has 2 pairs of sides that are equally long inside their pair.
and so you have in this case a perimeter of
2×6 + 2×4 = 12 + 8 = 20 in

Use a graphing calculator to sketch the graph of the quadratic equation, and then state the domain and range
y = x + 2x - 5
Answer:
d. D: allreal numbers
R: y>= -6
Step-by-step explanation:
You are allowed to use a graphing calculator to see the graph. See image.
This curve is a parabola. Upward and downward opening parabolas have a domain of all real numbers. Any x can be found on the graph and/or any x can be used in the equation without limit. That's "all real numbers"
See the graph does not exist below -6. Range is all the y's on the graph and/or all the possible y's the equation will spit out. Here we can clearly see the graph only exists from -6 and up. Range is y>= -6.

Please Help ! What is the slope of the line?
Answer:
There are 3 ways to find the slope of a line.
I'll use a simple method.
First, let's look at a random point on this line(and make sure it's close to the start of the line).
I'll choose (1,4).
Then, see how much it rises and how far it runs to another fixed point.
Though, in this case we can see that the rise is going down and the run is moving towards the right. So, the slope will be negative since the rise is negative.
You always want to confirm if it'll be a negative or positive slope and which direction the slope is guiding you to.
Now, if we go down 8 and over 3, we'll reach a fixed point of (4, -4).
Therefore, we can infer that the slope of this line will be 8/3.
Answer:
8/3
Step-by-step explanation:
rise over run, only clearly intercepts a point twice.
