Answer:
Number of people surveyed is 240 people
Step-by-step explanation:
We are told that Seventy-five percent of the people surveyed were pleased with the condition of the parks.
Now, if the number of people surveyed is represented by y, then number of people that were pleased with the condition of the parks = 75%y
This can be written as: 75y/100
Now, we are 180 people were pleased.
This means that;
75y/100 = 180
Let's multiply both sides by 100 to get;
(75y/100) × 100 = 180 × 100
This gives;. 75y = 18000
Divide both sides by 75 to get;
75y/75 = 18000/75
y = 240
Number of people surveyed is 240 people

glenn has 2 times as many hats so, h2 and then he has 4 less so -4
Answer:
It would be the first, 2h-4
Step-by-step explanation:
H stands for hats
We don’t have the numbers to solve, which we don’t need for this problem. But if we were solving we would multiply the amount of hats Mia has by two (2h). It says Glenn has four less than that, so you would then subtract four from whatever 2h would equal.
Find two fractions equivalent to each fraction of 8/36
Answer:
Thus, 2/9 is the simplified fraction for 8/36 by using the GCD or HCF method. Thus, 2/9 is the simplified fraction for 8/36 by using the prime factorization method.
Step-by-step explanation:
The two equivalent fractions for the given fraction are 4/18 and 2/9.
The given fraction is 8/36.
The equivalent fraction will be obtained by dividing or multiplying both the numerator and denominator of the fraction by same number.
Here, divide both the numerator and denominator by 2, we get
(8÷2)/(36÷2)
= 4/18
Again divide both the numerator and denominator by 2, we get
(4÷2)/(18÷2)
= 2/9
Therefore, the two equivalent fractions for the given fraction are 4/18 and 2/9.

The depth of a lake in Greenpoint changes over time due to rainfall and evaporation. This year it was 539 feet, which is 10% deeper than it was last year. What was last year's depth
Answer:
485.1 feets
Step-by-step explanation:
Given that:
Depth of Lake changes over time due to Rainfall and evaporation :
Depth this year = 539 feets
Depth this year is 10%deeper than last year's depth
Depth last year will be ;
Since, this year's depth is greater Than last year :
depth last year equals ; (depth this year - 10% of depth this year)
Depth last year:
539 - (0.1 *539)
539 - 53.9
= 485.1 feets

O y = -5x - 3
Oy=52 - 2
O y = 5x + 2
O y=-10 - 2
Answer:
y=-5x-3
Step-by-step explanation:
put -1 and 1 in equation and you will get the answer
The equation that best represents a line perpendicular will be y = - 5x - 3. Then the correct option is A.
What is the equation of a perpendicular line?Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0
The equation of the line passing through (-1, 2) and (1, -8). Then the equation of the line will be
y + 8 = [(-8 - 2) / (1 + 1)] (x - 1)
y + 8 = -5x + 5
y = - 5x - 3
The equation that best represents a line perpendicular will be y = - 5x - 3. Then the correct option is A.

Step-by-step explanation:
A freight elevator can carry a maximum cargo weight of 100,000 pounds . A convention center uses one of these elevators to move 2,500 pound containers. The total cargo weight is a function of the number of containers in the freight elevator and can be modeled by the equation f(x)=2500c . What is the domain and range?
Answer:
Domain: [0, 4]
Range: [0, 100000]
Step-by-step explanation:
Given the function:
[tex]f(x)=2500c[/tex]
Where [tex]c[/tex] is the number of container that can be carried by the freight elevator and
[tex]f(x)[/tex] is the total cargo weight.
Domain of any function is defined as the values that can be given as input and
Range of any function is defined as the values that can be of output.
Weight of each container = 2500 pound
Maximum weight that can be carried by the freight elevator = 100,000 pounds
Here, input is the number of containers.
Minimum of which can be 0 and maximum can be [tex]\frac{100000}{2500}=4[/tex]
So, domain is [0, 4] i.e. any value from {0, 1, 2, 3, 4}
Range is [0, 100000] i.e. any value between 0 and 100000 including both the values.
An object is 4900 ft above the ground. The object falls, and its height is given by the quadratic function: h(t) = −16t 2 + 4900 . The height of the object above the ground is in feet and the time, t, is in seconds. Determine when the object hits the ground.
Answer:
Step-by-step explanation:
The the height of an object modeled by the function
h(t) = −16t^2 + 4900
The object hits the ground when h(t) = 0
The equation becomes:
0 = −16t^2 + 4900
-16t² = -4900
t² = 4900/16
t² = 306.25
t = √306.25
t = 17.5 secs
This means that the object hits the ground after 17.5secs

Using a graphing or online calculator, graph this set of data on a scatter plot for reference. Then, in two or more complete sentences, explain why a quadratic function should be used to model this set of data.
Answer:
13.2m
Step-by-step explanation:
the initial vertical velocity of the ball is 25 sin 40 = 16.1m/s
since gravity reduces the vertical velocity of objects by 9.8m/s/s, this ball will reach max altitude in a time of
time = 16.1m/s / 9.8m/s/s = 1.6s
the max height is equivalent to the height an object will fall in 1.6s, so we have
height =1/2 g t^2 = 1/2 x 9.8m/s/s x (1.6s)^2 = 13.2m

If you borrow $500 for 4 years at
an annual interest rate of 6%, how
much will you pay altogether?
500×6/100×4=120 500+120=620
Step-by-step explanation:
[tex]\frac{500}{1}[/tex]×[tex]\frac{4}{1}[/tex]×[tex]\frac{6}{100}[/tex]=
Anything divided by one gives itself.
500*(4/1)*(6/100)
Anything divided by one gives itself.
500*4*(6/100)
Multiply 500 and 4 to get 2000.
2000*(6/100)
Reduce the fraction 6/100 to the lowest terms by extracting and canceling out 2.
2000*(3/50)
Express 2000×(3/50) as a single fraction.
[tex]\frac{2000*3}{50}[/tex]
Multiply 2000 and 3 to get 6000.
6000/50
Divide 6000 by 50 to get 120.
120
Add 500 to 120 because it is just your interest rate
500+120=620
You then get your full payment and it is $620.
