The ratio of soccer players to baseball players on two school teams is 4 to 7. Which of the following could be the number of players on each team?
A.
12 soccer players and 15 baseball players
B.
12 soccer players and 21 baseball players
C.
16 soccer players and 19 baseball players
D.
16 soccer players and 49 baseball players
Answer:
B
Step-by-step explanation:
Multiply each ratio by the same number
4x3=12 7x3=21
The number of players on each team could be; B. 12 soccer players and 21 baseball players.
What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b. Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.
We have been given that the ratio of soccer players to baseball players on two school teams is 4 to 7.
That is; 4: 7
Then Multiply each ratio by the same number.
4 x 3 = 12
7 x 3 = 21
Therefore, the number of players on each team could be; B. 12 soccer players and 21 baseball players.

The language arts teacher wants to know whether the students in the entire school prefer a debate or a speech. The teacher draws a random sample from the following groups:
A - All teachers in the school
B - All boys in each grade
C-All students in the speech club
D-All students in each grade
Which group best represents the population she should take a random sample from to get the best results for her survey?
Answer:
d- all students from each grade
Step-by-step explanation:
Answer:
D, all students in each grade.
Step-by-step explanation:
If you did a random sample from the students in the speech club it will be biased because they will probably all say giving speeches because they are in the speech CLUB. You cannot do the teahcers because their answers will also be biased. If you do all the boys in each grade it will be biased only to what boys like and not girls or any other student in the grade. Therefore, using the process of elimination, the answer is D, you should take a random sample of all the students in each grade.
You are tasked with constructing a rectangular box with a square base, an open top, and a volume of 184 in3. Determine what the dimensions of the box should be to minimize the surface area of the box. What is the minimum surface area? Keep your answer in radical form and omit units.
Answer:
7.17 by 7.17 by 3.58
Step-by-step explanation:
Since the rectangular box is square based, the total surface area is expressed as;
S = x²+2xh+2xh (the top is opened)
S = x² + 4xh ..... 1
x is the side length of the square
h is the height of the box
Also the volume V = x²h
Given V = 184
184 = x²h
h = 184/x² .... 2
Substitute 2 into 1;
S = x² + 4xh
S = x² + 4x(184/x²)
S = x² + 4(184/x)
S = x² + 736/x
Since we need a dimension that will minimize the surface area of the box then, dS/dx = 0
dS/dx = 2x -736/x²
0 = 2x -736/x²
multiply through by x²
0 = 2x³- 736
2x³ = 736
x³ = 736/2
x³ = 368
x = ∛368
x= 7.17 in
Since V = x²h
184 = 7.17²h
h = 184/7.17²
h = 184/51.4089
h = 3.58 in
Hence the dimensions of the box should be to minimize the surface area of the box are 7.17 by 7.17 by 3.58

2. 2x + y = -4
5x + 3y = -6
Answer:
x=15/4,y=-8.25
Step-by-step explanation:
Well to begin with it make both y's equal so multiply the first equation by 3 making it into: 6.6x+3y=-12. next subtract this new equation by the other one making it one equation as, 1.6x=-6, simplify to get: x=15/4, or 3.75 input that into one of the equations the secound one would be easier to make it 18.75+3y=-6 simplify again, 3y=-24.75 than you get y as y=-8.25

The zeros of a parabola are 6 and −5. If (-1, 3) is a point on the graph, which equation can be solved to find the value of a in the equation of the parabola?
A: 3 = a(−1 + 6)(−1 − 5)
B: 3 = a(−1 − 6)(−1 + 5)
C: −1 = a(3 + 6)(3 − 5)
D: −1 = a(3 − 6)(3 + 5)
Answer:
B:3=a(-1-6)(-1+5)
Step-by-step explanation:
The zeroes are 6 and -5 so we can write it as y=a(x-6)(x+5)
Now the point(-1,3) is on the line so substituting for x and y:
3=a(-1-6)(-1+5)

Answer:
x=50
Step-by-step explanation:
A= 30+2x
B= x
Supplementary angles are angles that always add up to 180 degrees.
therefore, A + B=180 degrees
30 + 2x + x = 180: Now we solve
30 + 3x =180
subtract 30 from both sides
3x=150
divide by 3
3x/3 = 150/3
x= 50

Step-by-step explanation:
Elias has read 18 pages of a book. He will continue to read at an average rate of 4 5 5 4 page per minute. The total number of pages (p) Elias reads after m minutes can be represented by the equation p = 4 5 m + 18 p= 5 4 m+18. How many minutes will it take Elias to read a total of 39 pages?
Answer:
26.25 minutes
Step-by-step explanation:
Given that :
Number of pages (p) read by Elias can be modeled by the function ;
p = 45m + 18
Where P = Number of pages ; m = number of minutes
Number of minutes it will take to read a total of 39 pages
p = 4/5m + 18
39 = 4/5m + 18
39 - 18 = 4/5m
21 = 4/5m
4m = 21 * 5
4m = 105
m = 105 / 4
m = 26.25

Answer:
50°
Step-by-step explanation:
angle 5 = angle 4 ( Alternative Interior Angles are equal )
But angle 3 & angle 4 are linear pairs. So,
angle 3 + angle 4 = 180°
=> angle 3 + angle 5 = 180° (angle 5 = angle 4)
=> angle 3 + 130° = 180°
=> angle 3 = 180° - 130° = 50°
