The middle school band has a boy to girl ratio of 4:6.
The band had 20 members last year and 25 members this year.
How many girls and how many boys are in the band in each of these two years?
Answer:
8:12Step-by-step explanation:
Ok so the starting ratio is 4:6
It is 20 members last year and 25 member the next year.
LAST: 20 THIS YEAR:25
When u use the ratio of 4:6 IN 25 students, u get
8:12 LAST year.
You can check because 8 + 12 = 20, or the total number of students.
show your work - and explain how to do it cuz im lost
Answer:
(0,7)
Step-by-step:
Slope is equal to the change in y over the change in x, or rise over run.
m= Change in y/Change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m= y2-y1/x2-y1
Substitute in the values of x and y into the equation to find the slope.
m= −8−(1)/5-(2)
Simplify the numerator.
Multiply −1 by 1.
m=-8-1/5-(2)
Subtract 1 from -8
m=-9/5-2
Simplify the denominator.
Multiply −1 by 2.
m=-9/5-2
Subtract 2 from 5
m=-9/3
Divide −9 by 3.
m=−3
Find the value of the y-intercept.
Substitute the value of m into the slope-intercept form of the equation, y=mx+b.
y=(−3)⋅x+b
Substitute the value of x into the slope-intercept form of the equation, y=mx+b
y=(−3)⋅(2)+b
Substitute the value of y into the slope-intercept form of the equation , y=mx+b.
1=(−3)⋅(2)+b
Rewrite the equation as (−3)⋅(2)+b=1.
(−3)⋅(2)+b=1
Multiply −3 by 2.
−6+b=1
Move all terms not containing b to the right side of the equation.
Add 6 to both sides of the equation.
b=1+6
Add 1 and 6.
b=7
List the slope and y-intercept.
Slope:−3
y-intercept: (0,7)

Step-by-step explanation:
A 2-column table with 4 rows. Column 1 is labeled x with entries 1, 2, 4, 5. Column 2 is labeled y with entries 15, 30, 60, 75. Does this table represent a proportional relationship? No. The points are not on the same line. No. The line does not pass through the origin. No. The ordered pairs do not make equivalent ratios. Yes. The points are on a line that passes through the origin.
Answer:
Yes
Step-by-step explanation:
The correct option is Yes, the points are on a line that passes through the origin.
Variation:From the information given in the table shown, we can see that as the value of x is increasing, the value of y is increasing. This shows a direct relationship.
If y is directly proportional to x, then;
y = kx
k = y/x
Given that x = 1 when y = 15
k = 15/1
k = 15
The equation that represents the table will be y = 15x
The correct option is Yes, the points are on a line that passes through the origin.

Griffin uses a courier service that charges $18.50 plus $0.25 per mile for each delivery. The courier’s fee for a delivery was $45.75. Griffin wrote this equation using x as the number of miles: 18.50 + 0.25x = 45.75.
Solve the equation to find the number of miles the courier drove.
Put the steps in order to solve the problem. Then solve.
(Please help!!)
Answer:
x=109
Step-by-step explanation:
18.50 + 0.25x = 45.75
-18.50. -18.50
0.25x=27.25
/0.25. /0.25
x=109

If a car traveling at 75 mph west, changes its direction to east, does it accelerate?
Answer:
Yes, that's right, a change in the direction of motion results in an acceleration even if the moving object neither sped up nor slowed down. That's because acceleration depends on the change in velocity and velocity is a vector quantity — one with both magnitude and direction.

Farmers have long used aquifers as a source of groundwater for irrigation, but when water is conserved, they have to dig even deeper into the Earth to extract the water they need. Which argument do you believe that farmers will face using this process?
Argument 2: This is an affordable process and it can have a huge impact on the agriculture industry.
Argument 3: Groundwater is a valuable resource in the United States only and farmers will not have a problem with needing water for their crops.
Argument 4: Groundwater is a valuable resource in the United States and throughout the world, but farmers have an unlimited supply.
Argument 1: This is a costly process and it can have a huge impact on the agriculture industry.
Answer:
Argument 1.
Step-by-step explanation: This is not cheap, and if becomes impossible or to costly, the farm industry will collapse. food shortages sure will follow.
Answer:
I believe it's argument 2.
Explanation:
Farmers don't have to pay to dig for water.

We can solve this by calculating the arch lengths on the track and adding them to the straight lengths on the track.
To calculate the arch lengths, we can pretend the arches are semicircles and calculate the arch length. We know that the diameter is 100 meters, and the circumference formula is diameter times pi. 100 times pi is 314, using 3.14 as pi, but we divide this by two since we are calculating the arch length of a semicircle, not a full circle. Dividing 314 by two gives us 157. However, we multiply this by two since we have to include the other arch's length and the lengths are the same, giving us 314 again. adding this to 200, the straight side lengths of the track, we get our final answer, 514 meters.
