what is the sum of x+52+67+75=1

The graph that represents the situation on the gymnast paying membership for yoga is Graph C.

The equation given for the amount spent in total by the gymnast is y = 10 + 20 x. What this means is that even if the gymnast takes no classes, he still has to pay the monthly fee of $ 10.

The graph should therefore begin at $10. If the gymnast takes 1 class, then the total cost for the month is:

= 10 + 20 ( 1 )

= $ 30

This is shown in the third graph so this is the correct graph.

Step-by-step explanation:

The potential energy of an object can be calculated as the sum of its kinetic and gravitational potential energy. At its highest point, the ball has zero kinetic energy, so the potential energy is equal to its gravitational potential energy.

The gravitational potential energy of an object is given by:

PE = m * g * h

where m is the mass of the object (7 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height above a reference point. In this case, the reference point is the ground, so h = 100 m.

Substituting in the given values, we find:

PE = 7 * 9.8 * 100 = 686 J

This is the potential energy of the ball at its highest point.

Answer: The equation 63 = 9k is correct.

To solve for k, you can divide both sides of the equation by 9:

63/9 = 9k/9

k = 7

So, k = 7 is the solution to the equation 63 = 9k.

Step-by-step explanation:

The value of k in the equation 63= 9k is 7

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.

The equation 63 = 9k is a type of linear equations with one variable.. The variable here is K

To find k;

63 = 9k

divide both sides by 9

63/9 = 9k/9

k = 7

therefore the value of k is 7

Answer:

y=4x-1

Explanation:

looking at the x row, as you can see, it goes up by 1 each time. In the y row, it goes up by 4, because -1+4=3, 3+4=7, etc. So your slope is 4, and in the funtion y=mx+b given, that would go in the “m” spot. Then for the “y” spot you need to figure out if x is 0, what is y. Well, that is given to you in the picture. It shows that when x=0, y=-1. So that is you y intercept, going into the b spot. If you put it together, it looks like this: “y=4x-1”.

Answer:

26 students

Step-by-step explanation:

We know

The ratio of students failing the test to students passing the test was 2/9

For every 11 students, 2 students fail the test, and 9 passes it.

2:9 = 11

143 students took the test. How many did not pass?

To get from 11 to 143, we time 13. To find how many did not pass, we take

2 times 13 = 26 students did not pass the test.

So, 26 students did not pass the test.

Answer:

e = 190

Step-by-step explanation:

Rearrange to:

e/(-95)+6-(4)=0

Now we simplify, and get this:

(e/-95 + 6) - 4 = 0

Rewrite the equation to get this:

6 = 6/1 = 6x(-95)/-95

after adding fraction with a common denominator we get:

(570 - e)/95 - 4 = 0

Rewrite the whole as an equivalent fraction:

4 = 4/1 = 4x95/95

After adding fractions with a common denominator we get:

190-e/95 = 0

Now we must get the numerator to equal 0:

190-e/95 x 95 = 0 x 95

We get:

190 - e = 0

So we solve:

-e + 190 = 0

Subtract 190 from both sides:

-e = -190

Multiply both sides by (-1):

e = 190

53.9 degree is the angle of the compass direction of a line connecting your starting point to your final position measured from north of west.

A compass is a tool for orientation and navigation that displays direction in relation to the four cardinal directions of the earth (or points). The directions north, south, east, and west are typically represented on the compass face as initialised abbreviations in a design called a compass rose. The rose can be aligned with the corresponding geographic directions when the compass is employed; for instance, the rose's "N" mark points northward. Compass roses are frequently joined with (or occasionally replaced by) marks indicating angles in degrees. East is 90° degrees, south is 180° degrees, and west is 270° degrees, with north being 0° and the angles increasing clockwise.

Here,

You started by travelling west to north.

The required system of equations equation besides y = 8x + 7 is y = 8x + 15  has no solution.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,

A system of equations has no solution when the equations describe lines that are parallel and do not intersect. In other words, there is no common solution for both equations, or in other words, there is no ordered pair that satisfies both equations.

If y = 8x + 7 is one of the equations, the other equation could be any line that is parallel to it and does not intersect it. This means that the other equation would have the same slope as y = 8x + 7, which is 8, but a different y-intercept.

For example, y = 8x + 15 is a line that is parallel to y = 8x + 7 and does not intersect it. Thus, the system of equations

The two numbers are 3 and 6. We can then solve for y using the quadratic formula:y = [9 ± √(81 - 120)]/2 , y = 3 or 6

The sum of two numbers (x + y) = 9

The product of two numbers (x * y) = 30

We can solve for x and y using the following equations:

x + y = 9

x * y = 30

We can solve for x by dividing both sides of the equation by y:

x = (30/y)

We can then substitute this into the first equation:

(30/y) + y = 9

We can then solve for y by subtracting 30/y from both sides:

y = 9 - (30/y)

We can then solve for y by multiplying both sides by y:

y^2 = 9y - 30

We can then solve for y using the quadratic formula:

y = [9 ± √(81 - 120)]/2

y = 3 or 6

Therefore, the two numbers are 3 and 6.

Step-by-step explanation: The degree represents the highest exponent in the function. In this case, there is a cubed term which has an exponent of 3. The leading coeffient represents the number before x that makes that highest exponent and in this case its 2.

The length, width, and height of the right square prism are all equal to 7units, i.e., 7units * 7units * 7units.

The volume of a right square prism can be expressed as the product of its length, width, and height. If the volume is 360 cubic units, and the prism is a square prism, then we can assume that its length, width, and height are all equal, so we can call them x. The volume formula can be expressed as:

V = x * x * x = 360

Taking the cube root of both sides of the equation, we get:

x = ∛(360) = 7.11

The cube root of 360 is approximately 7, so the length, width, and height of the square prism are all equal to 7 units.

The slope is negative three halves for option 2 and the y-intercept is 2. Hence option 2 is the correct answer.

A line's steepness and direction are determined by the line's slope. Without actually using a compass, determining a line's slope in a coordinate plane can aid in determining whether the line is parallel, perpendicular, or not.

Any two clearly separated points on a line can be used to calculate the slope of any line. Calculated using the slope of a line formula, the ratio of "vertical change" to "horizontal change" between two different locations on a line is determined.

The y-intercept is obtained when the x coordinate is 0.

From the given options the y-intercept is 2 for option 1 and 2.

The slope is given as:

m = (y2 - y1) / (x2 - x1)

For option 1:

m = (0 - 2) / (3 - 0)

m = -2/3

For option 2:

m = (-1 - 2) / (2 - 0)

m = -3/2

Among the 3 cards the probability of picking an odd number and then picking an odd number is 1/3.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

The probability of picking a card with odd number is -

Probability = Favourable outcomes / Total outcomes

Substitute the values in the equation -

P(odd1) = Odd number of cards / Total number of cards

P(odd1) = [tex]\frac{^1C_1}{^3C_1}[/tex]

P(odd1) = 1/3

This is followed by picking up a second card without putting the first card back.

So, out of remaining two cards an odd card needs to be picked.

Probability = Favourable outcomes / Total outcomes

Substitute the values in the equation -

P(odd2) = Remaining odd number of cards / Remaining number of cards

P(odd2) = [tex]\frac{^0C_1}{^1C_1}[/tex]

P(odd2) = 0/1

P(odd2) = 0

The probability of both the events is -

P(odd1) + P(odd2)

1/3 + 0

1/3

Therefore, the probability value is 1/3.
