Answer:

The answers are as follows:

2 Green = 25%

2 Red = 4%

1 Black 1 Green = 15%

1 Green 1 Red = 10%

Step-by-step explanation:

In order to find any of these, we first have to find the probability of pulling any of them individually. To find that, we simply divide the number of marbles by the total in the jar.

Green = 5/10 = 50%

Black = 3/10 = 30%

Red = 2/10 = 20%

Now to find any combination, simply multiply the percentages together. For instance, for 1 black and 1 green, multiply those percentages together.

Black * Green

30% * 50% = 15%

You can do this for any number of combinations

Answer:

9 quarters and 12 nickles

Step-by-step explanation:

9 quarters = $2.25

12 nickles = .60

$2.25 + .60 = 2.85

12 is 3 more than 9

Answer: 8.50 dollars

The result is positive, so this is a gain (instead of a loss)

====================================

Explanation:

Focus on the "stock JKL" row only when it comes to the percentages we'll use. We need to convert them to decimal form

15% ---> 0.15

65% ---> 0.65

20% ---> 0.20

I just moved the decimal point over 2 spots, or you can divide by 100 (eg: 15% = 15/100 = 0.15)

Multiply each of these values by their corresponding loss or gain. Use negative numbers for losses

15% chance of losing $25 ---> 0.15*(-25) = -3.75

65% chance of winning $5 ---> 0.65*(5) = 3.25

20% chance of winning $45 ---> 0.20*(45) = 9

Now add up those results: -3.75+3.25+9 = 8.50

s in the expression s • (16) = 2.5  represents the speed in miles per hour.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

here,
A theme park has a tram that goes around the 2.5-mile perimeter of the park in 10 minutes.
So,
Speed = 2.5 miles / 10 minutes

Since, 1 hour = 60 minutes,
And 1 minute = 1/60 hours,

Now, converting the unit of speed of tram from miles per minute to miles per hour where,
Speed = 2.5 miles / 10 (1/60 hours)
Speed = s (say)

s = 2.5/ (1/6)
s (1/6) = 2.5

hence, s in the above expression represents the speed.

Final answer:

The symbol 's' in the equation represents the speed of the tram in miles per minute

Explanation:

The student's question involves solving for the speed s of a tram that goes around the perimeter of a theme park. The equation provided is s (16) = 2.5, where s represents the speed of the tram in miles per minute. To find the value of s, we need to divide both sides of the equation by 16, which yields:

s = 2.5 / 16

Now, performing the division gives us:

s = 0.15625

Therefore, the speed of the tram is 0.15625 miles per minute.

Answer:

The Answer is c) 6

Step-by-step explanation:

Solve for x:

5 (x - 3) + 7 = 22

5 (x - 3) = 5 x - 15:

5 x - 15 + 7 = 22

Grouping like terms, 5 x - 15 + 7 = 5 x + (7 - 15):

5 x + (7 - 15) = 22

7 - 15 = -8:

5 x + -8 = 22

Add 8 to both sides:

5 x + (8 - 8) = 8 + 22

8 - 8 = 0:

5 x = 22 + 8

22 + 8 = 30:

5 x = 30

Divide both sides of 5 x = 30 by 5:

(5 x)/5 = 30/5

5/5 = 1:

x = 30/5

The gcd of 30 and 5 is 5, so 30/5 = (5×6)/(5×1) = 5/5×6 = 6:

Answer:  x = 6

Answer:

x=6

Step-by-step explanation:

7 + 5(x - 3) = 22

The first step is to distribute the 5

7+ 5x-5*3 =22

7+ 5x-15 =22

Combine like terms

5x-8 =22

Add 8 to each side

5x-8+8 =22+8

5x = 30

5x/5 = 30/5

Answer:

The equation of the line would be y = 1/3x + 2

Step-by-step explanation:

To find this, we must first solve the original equation for y.

3x + y = 6

y = -3x + 6

This means the original slope is -3. Since the original slope is -3, we know that the perpendicular slope is 1/3. This is because perpendicular slopes are opposite and reciprocal.

Now we use the slope and the intercept in slope-intercept form to get the equation.

y = mx + b

y = 1/3x + 2

The equation of a line perpendicular to the line 3x + y = 6 and passing through the y-intercept of 2 is y = 1/3x + 2.

To find the equation of a line that is perpendicular to a given line and passes through a certain y-intercept, we first find the slope of the given line, and then use the negative reciprocal of that slope as the slope of the new line.

The given line is in standard form 3x + y = 6. To convert it to slope-intercept form, we isolate y: y = -3x + 6. Therefore, the slope of the given line is -3. The slope of any line perpendicular to this line is the negative reciprocal of this slope, or 1/3.

The new line must pass through the point where y = 2. So, we plug this value into the slope-intercept form of the equation: y = mx + b, where m is the slope and b is the y-intercept. As a result, the new equation is: y = 1/3x + 2.

4. x=2 y=3

5. x=-3, y=-6

6. x=0, y=6.5

Step-by-step explanation:

A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. To use substitution, we substitute a equivalent expression in for a variable and solve for the remaining variable. We then substitute again to find the other variable.

y=5x-7  & -3x-2y=-12

We will input for y, the expression 5x-7 into -3x-2y=-12. We will then isolate x to solve for it using inverse operations.

-3x-2(5x-7)=-12

-3x-10x+14=-12

-13x+14=-12

-13x+14-14=-12-14

-13x=-26

x=2

We substitute back in now to solve for y. y=5(x)-7=5(2)-7=10=7=3

-4x+y=6  & -5x-y=21

We will input for y, the expression 6+4x into -5x-y=21. We will then isolate x to solve for it using inverse operations.

-5x-(4x+6)=21

-5x-4x-6=21

-9x-6=21

-9x-6+6=21+6

-9x=27

x=-3

We substitute back in now to solve for y. y=4(x)+6=4(-3)+6=-12+6=-6

-7x-2y=-13  & x-2y=-13

We will input for x, the expression 2y-13 into -7x-2y=-13. We will then isolate y to solve for it using inverse operations.

-7(2y-13)-2y=-13

-7(2y)+-7(-13)-2y=-13

-14y+91-2y=-13

-16y+91=-13

-16y+91-91=-13-91

-16y=-104

y=6.5

We substitute back in now to solve for x. x=2y-13=2(6.5)-13=13-13=0.

Answer:

the maximum height is 1054.500 meters

Step-by-step explanation:

h ( t ) = − 4.9t^2 + 133t + 152

a= -4.9 , b= 133  and c= 152

To find maximum height , we find vertex

[tex]x= \frac{-b}{2a}=\frac{-133}{2(-4.9)}= 13.5714 [/tex]

Now plug in 13.5714 for 't' in h(t)

[tex]h(t) =-4.9t^2 + 133t + 152[/tex]

[tex]h(t)=-4.9( 13.5714)^2 + 133( 13.5714)+ 152=1054.500[/tex]

the maximum height = 1054.500 meters

The maximum height of the drone is approximately 1347.174 meters.

To find the maximum height of the drone, we need to find the vertex of the quadratic function h(t) = -4.9t^2 + 133t + 152. The vertex of a quadratic function in the form f(t) = at^2 + bt + c is given by the coordinates (t, f(t)) where t = -b/2a and f(t) is the maximum value.

Plugging in the values from our function, we have t = -133/(2*(-4.9)) = 13.67347. Substituting this value of t back into the function, we get h(13.67347) = -4.9*(13.67347)^2 + 133*(13.67347) + 152 = 1347.174 meters. Therefore, the maximum height of the drone is approximately 1347.174 meters.

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

We will use the math operation division to find the answer. Division takes a total and divides it into equal amounts. We have a total of 96 and need equal amounts in to each of the 12 groups.

96/12=8 students per group

To divide 96 students into 12 equal groups, you perform a division operation. Using 96 / 12, we find that there are eight students per group.

To determine how many students will be in each of the 12 equal groups, you use division. The total number of students which is 96 will be divided by the number of groups which is 12. Therefore, the equation you need is 96 / 12 = eight students per group.

This division operation is similar to when five students working on a group assignment divide it into five equal parts. Each of the students completes one part. In our scenario, instead of five parts, we are dividing 96 students into 12 parts, hence creating equal groups for the gym class activity.

The midpoint of line segment MN with endpoints M (6, 14) and N (-4, -4) can be calculated using the formula: ( (x1 + x2) / 2, (y1 + y2) / 2 ) which gives the midpoint coordinates as (1, 5).

In order to find the midpoint of a line segment in a 2-dimensional space, you can use the midpoint formula: ( (x1 + x2) / 2, (y1 + y2) / 2 ). For the given endpoints M (6, 14) and N(-4, -4), substitute the respective values into the formula:

X-Midpoint = (6 + -4) / 2 = 1

Y-Midpoint = (14 + -4) / 2 = 5

Thus, the coordinates of the midpoint of segment MN are (1, 5).

Answer:

(a) A system of equations:

[tex]0.38x+1.56y = 24.80[/tex]  

[tex]x+y = 28[/tex]

(b) Number of blocks were in the order is, 12

Step-by-step explanation:

(a)

Let x represents the number of bricks and y represents the number of blocks.

As per the given statement:

A bricks costs $ 0.38 and a block costs $1.56.

Total  bricks costs = 0.38x and total block costs = 1.56y

The brickyard filled $24.80 order.

⇒ [tex]0.38x+1.56y = 24.80[/tex]                          ......[1]

Since, it contained 28 items.

⇒[tex]x+y = 28[/tex]                                               ....[2]

Multiply equation [2] both sides by 0.38 we have;

[tex]0.38(x+y) = 0.38 \times 28[/tex]

Using distributive property: [tex]a\cdot (b+c) = a\cdot b + a\cdot c[/tex]

0.38x +0.38 y = 10.64                                        ......[3]

Subtract equation [3] from [1] to get x eliminated ;

[tex]0.38x+1.56y -0.38x -0.38y= 24.80 - 10.64[/tex]  

Combine like terms;

1.18y =14.16

Divide both sides by 1.18 we have;

[tex]\frac{1.18y}{1.18} = \frac{14.16}{1.18}[/tex]

Simplify:

[tex]y = 12[/tex]

Substitutes this y value in equation [2] to solve for x;

x + 12= 28

Subtract 12 from both sides we get;

x +12-12 =28-12

Simplify:

x = 16

Therefore, a system of equations that can be used to find the number of bricks and the number of blocks in the order:

[tex]0.38x+1.56y = 24.80[/tex]  

[tex]x+y = 28[/tex]

(b)

The number of blocks are in order(y), is  12.

So, in this case, the raph doesn't have a returning point like a parabola or an U movement, that means possible answers are A and B.

Choice B cannot be the answer because the negative sign in the first term indicates a reflection accros the vertical axis, and the graph is showing an original function.
