Answer: 8 gumballs

Step-by-step explanation:

We can solve this problem with the Rule of three, since we are given as data three factors and one is unknown.

If 2 gumballs cost 8 cents, how many gumballs can we buy with 32 cents?:

[tex]2 gumballs[/tex]-----[tex]8 cents[/tex]

[tex]x[/tex]-----[tex]32 cents[/tex]

Then:

[tex]x=\frac{(2 gumballs)(32 cents)}{8 cents}[/tex]

[tex]x=8 gumballs[/tex] We can buy 8 gumballs with 32 cents

Step-by-step explanation:

(9-4)/(5+7)= 5/12

y - 4 = 5/12(x + 7)

y - 48/12 = (5/12)x + 35/12

y = (5/12)x + 83/12

In a system of two linear equations if the slopes are same then no solutions and different slope means exactly one solution.

Step-by-step explanation:

Let us consider two linear equations, each linear equation has slope and y-intercept.

Among those slope plays a major role, if there are no slope means than the line equation will be parallel to the x-axis. The slope will indicate the line's direction.

If two linear equations, having an identical slope then they will become like parallel lines. Thus the parallel lines won't intersect with each other. So there will be no solutions to the system.  (refer 1st image of both equations having slope 5)

If two linear equations have different slope they will intersect at any point. That is, it will result in exactly one solution. (refer 2nd image of both equations having different equations 1 and -1).

To find the slope of g(x), use the slope formula(m):

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]        And plug in two points, I will use:

(0, 2) = (x₁, y₁)

(5, 4) = (x₂, y₂)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{4-2}{5-0}[/tex]

[tex]m=\frac{2}{5}[/tex]

You could do the same to find f(x) by finding two points and using the slope formula, or you could use this to tell visibly:

[tex]m=\frac{rise}{run}[/tex]

Rise is the number of units you go up(+) or down(-) from each distinguished point

Run is the number of units you go to the right from each distinguished point

If you look at the graph, you can see the points (0, -1) and (3, 1). From each point, you go up 2 units and to the right 3 units (you can make sure by using another point). So the slope of f(x) is  [tex]\frac{2}{3}[/tex]

Whichever line looks more vertical(and is positive) has the greater slope. So the slope of f(x) is greater than the slope of g(x). The answer is option A

Answer:

w=4.9

Step-by-step explanation:

If you are solving for w, you want to isolate the variable. If it is easier to write it out, it would look something like this..

-5 x w = -24.5

To get w by itself, use the inverse of multiplication, which is division. Divide the expression to the left of the equal sign by -5. Remember, what you do to one side, you must do to the other. When you divide -24.5 by -5, you end up with

w=4.9

Answer:

65 degrees

25 degrees

Step-by-step explanation:

x=first angle

y=second angle

x+y=90            x-y=40

                       x=40+y

(40+y)+y=90

40+2y=90

2y=50

y=25

                      x=40+25

                         x=65

Final answer:

The sum and difference of two angles can be found by setting up a system of equations and solving it. In this case, the two angles are 65 degrees and 25 degrees.

Explanation:

The question is asking for the sum and difference of two angles. Let's represent the two angles as x and y. We know that the sum of the two angles is 90 degrees, so we can write the equation x + y = 90. We also know that the difference of the two angles is 40 degrees, so we can write the equation x - y = 40.

We can solve this system of equations using substitution or elimination. Let's use the substitution method. From the second equation, we can rewrite it as x = y + 40. Substitute this value of x into the first equation:

(y + 40) + y = 90. Combine like terms: 2y + 40 = 90. Subtract 40 from both sides: 2y = 50. Divide by 2: y = 25.

Now substitute this value of y back into the equation x = y + 40: x = 25 + 40 = 65.

So, the two angles are x = 65 degrees and y = 25 degrees.

Answer:

5817 Newtons.

Step-by-step explanation:

Total mass of the cage + the miners = 700 Kg which is a downward force of  700g N.

The net downward force = 700g - T where T is the tension (force) in the cable. The g = acceleration due to gravity = 9.81 m s-2.

We  calculate the  acceleration of the cage by using an equation of motion:

Distance = ut + 1/2 a t^2     where u = initial velocity , t = time and a = acceleration:

75 = 0(t) + 1/2 a (10^2)

50a =  75

a = 1.5 m s-2.

So using Newtons second law of motion

Force = mass * acceleration:

700*9.81 - T = 700 * 1.5

T = 700 * 9.81 - 700*1.5

= 5817 N.

The force in the cable during the first 10 seconds is 7930N. This was determined using the formulas s = ut + 1/2at² (to calculate acceleration) and F = ma + mg (to calculate the force).

The subject of this question is Physics, specifically dealing with forces and acceleration. The total weight of the miners and the cage equals the sum of the miners' weight and the cage's weight, giving a total of 700kg, using the formula weight = mass x gravity (assumed to be 9.8m/s²). Therefore, the total weight is 700kg x 9.8m/s² = 6860N.

Then, we'd calculate the acceleration. The formula used is s = ut + 1/2at², where s is distance, u is initial velocity, a is acceleration, and t is time. Given that initial velocity is 0, the formula is simplified to s = 1/2at². After rearranging, we get acceleration (a) = 2s/t² = 2*75/10² = 1.5m/s².

Finally, we can determine the force on the cable using the formula F = ma + mg (F = force, m = mass, a = acceleration, g = gravity). Substituting, we get F = 700kg x 1.5m/s² + 700kg x 9.8m/s² = 7930N. Therefore, the force in the cable during the first 10 seconds is 7930N.

Final answer:

To write an equation with (1,3) as a solution, choose an arbitrary slope and use the given point to solve for the y-intercept, forming a complete linear equation.

Explanation:

To write an equation in two variables that has (1,3) as a solution, you start by understanding linear equations in the form y = mx + b, where m is the slope, and b is the y-intercept. Given the point (1,3), we can choose an arbitrary slope (for example, 2) and plug the point into the equation to solve for b.

Note: y = 2x + b, and with the point (1,3), substituting x with 1 and y with 3 gives 3 = 2(1) + b, which simplifies to b = 1. Therefore, an example equation that fits the criteria is y = 2x + 1.

The width of the garden is 9 feet.

The length of the garden is 15 feet.

Step-by-step explanation:

Area of the rectangle = length[tex]\times[/tex]width

⇒ 135 = (x+6)x

⇒ 135 = x² + 6x

⇒ x²+6x-135 = 0

Using factorization method,

x²+6x-135 = 0

⇒ (x+15)(x-9) = 0

∴ x = -15 and x = 9

The width of the garden is 9 feet.

The length of the garden is (x+6) = 15 feet.

By assigning a variable to the width of the garden and using the provided length and area, we can create and solve an equation which tells us that the width of the garden is 9 feet and the length is 15 feet.

Let's assign the width of the vegetable garden as 'x', so the length of the garden would be 'x + 6' feet because we know it is 6 feet longer than the width. The area of a rectangle is computed by multiplying the length and the width. So, the equation we come up with, based on the question, is 'x(x + 6) = 135' square feet.

Let's solve this equation. We first expand the multiplication on the left-hand side which gives us 'x2 + 6x = 135'. By rearranging this equation, we set it to zero: 'x2 + 6x - 135 = 0'. Subsequently, we can factor this equation to ' (x - 9)(x + 15) = 0'. Setting each factor equal to zero gives us the solutions 'x = 9' or 'x = -15'. However, since a negative width doesn't make sense in this context, we discard '-15'. Therefore, the width of the garden is 9 feet, and the length is 9 + 6 = 15 feet.

Final answer:

The approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth is about 14.7 meters.

Explanation:

To find the approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth, we can use the formula for the period of a pendulum:

T = 2π √(L/g)

Where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.

Given that the period is 2.4 pi seconds, we can substitute this value into the formula:

2.4 pi = 2π √(L/g)

Simplifying the equation, we can divide both sides by 2π:

1.2 = √(L/g)

Squaring both sides of the equation, we get:

1.44 = L/g

Since we don't have the value of g, we cannot solve for L exactly. However, if we assume that g is approximately 9.8 m/s², which is the average acceleration due to gravity on Earth, we can estimate the value of L:

1.44 = L/9.8

Multiplying both sides by 9.8, we find:

L ≈ 14.7 m

Answer:

Neither positive nor negative—the sum is zero.

Step-by-step explanation:

Final answer:

The mathematics problem involves cancelled positive and negative numbers. Adding a number to its negative results in zero. Therefore, the expression simplifies to zero.

Explanation:

The question provided appears to be a mathematics problem that involves adding a number and its negative equivalent. Specifically, it looks like the sum of 123 and 1/23 plus the negative of 123 and 1/23 is being asked.

When you sum a number and its negative, they cancel each other out, resulting in zero. This is because the definition of a negative number is that it's the additive inverse of its positive counterpart, meaning when the two are added together, their sum is zero. The calculation is straightforward:

123 and 1/23 + (-123 and 1/23) = 0.

Answer:

Step-by-step explanation:

y = 5/3x + 5...in y = mx + b form, the slope is in the m position and the y int is in the b position.

so we have a slope of 5/3 and a y int of 5.....(0,5)

the x int can be found by subbing in 0 for y and solving for x

0 = 5/3x + 5

-5/3x = 5

x = 5 * -3/5

x = -15/5

x = -3......so ur x int is (-3,0)

go ahead and plot ur intercepts....(0,5) and (-3,0).....now start at (-3,0)....and since ur slope is 5/3....go up 5 spaces and to the right 3 spaces...plot that point.....then go up 5 and to the right 3...plot that point....keep doing this pattern....u should cross the y axis at (0,5). Then just connect ur dots and u have ur line.

It’s A. I go To Uva too

Step-by-step explanation:

Dalton has 4 ten-dollar bills and 3 twenty-dollar bills.

To find out how many of each bill Dalton has, we can set up a system of equations.

Let's assume Dalton has x number of ten-dollar bills and y number of twenty-dollar bills. The total number of bills he has is given as 7, so we have the equation: x + y = 7.

Additionally, the total value of the bills is given as $100. Since each ten-dollar bill is worth 10 dollars and each twenty-dollar bill is worth 20 dollars, we have the equation: 10x+20y = 100.

Now we can solve the system of equations to find the values of x and y.

Multiplying the first equation by 10 to eliminate x, we have: 10x + 10y = 70.

Subtracting this equation from the second equation, we get: 10x + 20y - (10x + 10y) = 100 - 70.

Simplifying, we have: 10y = 30.

Dividing both sides of the equation by 10, we find that y = 3.

Substituting this value back into the first equation, we can solve for x: x + 3 = 7.

Subtracting 3 from both sides, we find that x = 4.

Therefore, Dalton has 4 ten-dollar bills and 3 twenty-dollar bills.
