Answer: f - 36
Step-by-step explanation:
Number of frogs in the pond originally was f.
Then 36 of them hopped away which means that these 36 have to be subtracted from the original f to find out the number of frogs still in the bond.
Expression is therefore:
= Number of frogs originally in the pond - Number of frogs that left
= f - 36

Baking Brownies
A brownie recipe needs one cup of sugar for every 1⁄2 cup of flour to make a batch of cookies. To make multiple batches, we represent the relationship between flour and sugar with the function f = 1⁄2 s where f is the number of cups of flour and s the number of cups of sugar. What graph represents this relationship?
Answer:
A
Step-by-step explanation:
A because it is the only one the recipe calls for 1 cup of sugar and 1/2 cup of flour, the point is in the middle but also on one.

A researcher wished to compare the average amount of time spent in extracurricular activities by high school students in a suburban school district with that of high schoolers in a school district of a large city. The researcher obtained an SRS of 60 high school students in a large suburban school district and found the mean time spent in extracurricular activities per week to be x1 = 6 hours, with a standard deviation s1 = 3 hours. The researcher also obtained an independent SRS of 40 high school students in a large city school district and found the mean time spent in extracurricular activities per week to be x2 = 4 hours, with a standard deviation s2 = 2 hours. Let u1 and u2 represent the mean amount of time spent in extracurricular activities per week by the populations of all high school students in the suburban and city school districts, respectively. Assume the two-sample t-procedures are safe to use.
With a level of 5%, test the hypothesis that the amount of time spent on extracurricular activities is no different in the two groups.
For the problem above, a 95% confidence interval for u1-u2 is (use the conservative value for the degrees of freedom)
a. 2 +- 0.5 hours.
b. 2 +- 0.84 hours.
c. 2 +- 1.01 hours.

which is longest 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters
Answer:
30 Kilometers
Step-by-step explanation:
The longest measure from the given measures is 30 kilometers.
A no. of measurement values are given in the question.
We have to find out which is the longest from them.
What is the meaning of unit conversion ?
A unit conversion is done to express the same property as a different unit of measurement.
As per the question ;
Some measures i.e., 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters are given.
Let's check which is the longest by converting them all in same units say centimeters.
So ;
a) 90 centimeters
= 90 centimeters
b) 40 meters
= 40 × 100 centimeters
= 4000 centimeters
c) 30 kilometers
= 30 × 1000 meters
= 30000 × 100 centimeters
= 3000000 centimeters
d) 10 meters
= 10 × 100
= 1000 centimeters
e) 40 millimeters
= 40 / 10 centimeters
= 4 centimeters
So ; the longest is 30 kilometers.
Thus , the longest measure from the given measures is 30 kilometers.

Convert the equation to Standard Form.
y=2(x+1)^(2)-4
Answer:
y = 2x^2 + 4x - 2
Step-by-step explanation:
y=2(x+1)^(2)-4 is in vertex form. We want the same equation in standard form, which looks like y = ax^2 + bx + c.
Perform the indicated multiplication (squaring of x + 1):
y = 2(x^2 + 2x + 1) - 4, or
y = 2x^2 + 4x + 2 - 4, or
y = 2x^2 + 4x - 2 This is in the standard form of a quadatic.

Step-by-step explanation:
Put the numbers in order from least to greatest.
72, 73, 75, 76, 76, 79, 83, 86
Then, cross off each number at each end until you reach the one in the middle. Which, since they are the same, is 76.
to rent a certain meeting room, a college charges a reservation fee of $18 and an additional fee of $6 per hour. The chemistry club wants to spend at most $72 on renting the room. what are the possible numbers of hours the cemetery club could rent the meeting room? use t for the number of hours. write your answer as an inequality solved for t.
Answer:
t ≤ 9 hours
Step-by-step explanation:
Reservation fee = $18
Additional fee per hour = $6
Let x = number of hours
At most in inequality means ≤ less than or equal to
The inequality is

David made a batch of 5 liters of blue liquid everyday for 3 days how many milliliters of blue liquid did he make in all
Answer: 15000 millimeters
Step-by-step explanation:
Since David David made a batch of 5 liters of blue liquid everyday. The number of liters that'll be made for 3 days will be:
= 5 liters × 3
= 15 liters
We should note that 1000 millimeters = 1 liter. Therefore, 15 liters will be converted to millimeters which will be:
= 15 × 1000
= 15000 millimeters

At a school. Number of boys:number of girls=11:9. There are 124 more boys than girl. Work out the total number of students at the school
Answer:
Total students = 1240
Step-by-step explanation:
Given that,
Number of boys: number of girls=11:9
[tex]\dfrac{x}{y}=\dfrac{11}{9}\\\\9x=11y[/tex] ......(1)
There are 124 more boys than girls i.e.
x = 124+y .....(2)
Put the value of x from equation (2) in equation (1). So,
9(124+y) = 11y
1116 +9y = 11y
1116 = 2y
y = 558
Put the value of y in equation (2).
x = 124+558
x = 682
Total students = x+y
= 682+558
= 1240
So, there are 1240 students at the school.
