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.

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.

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.

A street light is 7.5 feet tall casts a 3-foot-long shadow A nearby flagpole casts a 16.5 foot long shadow what is the height of the flag pole
Answer:
h = 41.25 foot
Step-by-step explanation:
Given that,
Height of a street light = 7.5 feet
It casts a 3-foot-long shadow.
A nearby flagpole casts a 16.5 foot long shadow. We need to find the height of the flag pole. Let the height be h. It can be calculated as :
[tex]\dfrac{\text{height of street light}}{\text{height of shadow of street light}}=\dfrac{\text{height of flagpole}}{\text{height of shadow of the flag pole}}\\\\\dfrac{7.5}{3}=\dfrac{h}{16.5}\\\\h=\dfrac{7.5\times 16.5}{3}\\\\h=41.25\ foot[/tex]
So, the height of the flag pole is equal to 41.25 foot.
The height of the flag pole is 41.25 feet tall.
Word problems in mathematics are methods used to solve real-life cases. They usually follow a logical approach with the use of arithmetic operations when solving them.
From the parameters given:
If 7.5 feet tall casts = 3-foot long shadowLet the height of the flag pole be = x
∴
(x) feet tall casts = 16.5 foot long shadow.To determine the height of the flag pole, we have:
[tex]\mathbf{x = \dfrac{7.5 feet \ tall \times 16.5 \ foot \ long} {3 \ foot \ long} }[/tex]
x = 41.25 feet tall

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

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)

- Multiply the coefficient of the first term by the constant 1 -7 = -7
- Find two factors of -7 whose sum equals the coefficient of the middle term, which is -6 .
-7+ 1 = -6
-Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and 1.

A quantity with an initial value of 980 decays exponentially at a rate of 0.3% every 6 decades. What is the value of the quantity after 49 decades, to the nearest
hundredth?
Answer:
956.73
Step-by-step explanation:
0.3% = 0.003
1-0.003 = 0.997
49/6 = 8 r1 (use 8 because decay is not continuous)
0.997^8 = 0.97625...
0.97625... x 980 ≈ 956.73

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.
