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.

Infinite solutions

Step-by-step explanation:

I converted y + 2 = -5x into y=-5x-2

The two equation are the same (coinciding lines) and therefore have the same points and they have an infinite amount of solutions.

Answer:

1/5 = 0.2 so, she can drink 0.1 of a gallon each day

to turn a fraction into a decimal you should do..

1/5 since 5 can't go into 1 you add a 0 to the 1 making it a 10 and move the decimal point, since 5 goes into 10, 2 times, we get 0.2

Answer:

maybe y= 9 because side A B is 10 and side C D is almost the same just sleep slightly shorter.

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:

8. 3x + 2 < or = 5

3x < or = 5 - 2

3x < or = 3

x < or = 1

0 and 1 you have to look at the conditions x ...W

The equation represents from starting position of 3 meters below sea level, the fish is descending 7 meters per second. Then the correct option is C.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

A fish is swimming at a constant rate toward the ocean floor. The equation y = – 7x – 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.

The equation represents from starting position of 3 meters below sea level, the fish is descending 7 meters per second. Then the correct option is C.

The complete question is attached below.

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:

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

Answer:

Part 1: Number of extra round balloons that long balloons = 12 balloons

Part 2 : Leftover blown-up balloons = 247 balloons

Note: The question is incomplete. The complete question is given below:

A clown bought 5 bags of round balloons with 24 balloons in each bag. the clown also bought 3 bags of long balloons with 36 balloons in each bag.

Part 1

How many more round balloons than long balloons did the clown buy?

Part 2 out of 2

The clown also bought 3 bags of heart-shaped balloons with 14 balloons in each bag. when the clown blew up all of the round, long, and heart-shaped balloons, 23 balloons burst. How many blown-up balloons were left? explain your answer.

Step-by-step explanation:

Step 1 : Finding the total number of each balloon

Round balloon = 5 × 24 = 120 balloons

Long balloons = 3 × 36 = 108 balloons

Heart-shaped balloons = 3 × 14 = 42 balloons.

Part 1:

Number of extra round balloons that long balloons = 120 - 108

Number of extra round balloons that long balloons = 12 balloons

Part 2:

Total number of balloons = 120 + 108 + 42 = 270 balloons.

Number of burst balloons = 23

Leftover blown-up balloons = 270 - 23 Leftover blown-up balloons = 247 balloons

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

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°

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.

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.
