Answer:

9 pieces

Explanation:

From the question, we're told that the length of the stick is 10 1/5 inches, let's convert the mixed fraction into an improper fraction;

Also, we're told that the stick was cut into shorter pieces of length 1 2/15 inches each. Converting 1 2/15 into an improper fraction, we'll have;

To determine the number of pieces that the stick will be cut into, we'll need to divide 51/5 by 17/15;

The value of x can be determined as,

In triangle ABC,

Since the graphs are parallel to each other, there is no solution to the system. If a system has no solution, it is said to be an inconsistent system. So, the given system is inconsistent.

The solution of the simultaneous equation using substitution is

(x ,y) = (-9,-4) .

The given system of equation are:

x=-9............................................1

-4x+4y=20 ...............................2

Now we will simplify the equation 2

or, -x + y = 5

now we will substitute the value of x in the equation 2

or, -(-9) + y = 5

or, 9+ y= 5

or, y = -4

Two or more algebra equations that share variables, such as x and y, are said to be simultaneous equations. Since the equations are resolved simultaneously, they are known as simultaneous equations. Each equation represents a straight line.

These equations alone could have an endless number of solutions. There are several ways to solve the simultaneous linear equations.

The simultaneous equations can be solved using one of four methods:

Hence the values of x and y are -9 and -4 respectively.

From the question, there are some scenarios we need to cater for:

- The team is down 14 points.

- It is a given that the team scores 2 touchdowns whatever the case. This means the team has 12 points in the bag.

- That leaves 2 points to overturn the loss, or draw or lose

If the team wins:

The team can only win if they score their 2 points runs twice. i.e. An increase in 4 points from the two plays would overturn the score and the team would lead the game by 2 points.

The question asks us to find the probability of the team winning if the team goes for 2 points after each 6-point touchdown.

We can solve this as:

If the team loses:

If the team loses, there are some scenarios to take into consideration:

1. If the team tries 1 point plays and succeeds one time and failing the other time

2. If the team tries 1 point plays and fails twice.

3. If the team tries 2 point plays and they fail twice. (i.e. if they succeed even once, they can draw the match

The general form of a quadratic is:

We need to plug in the 3 pair of points into "x" and "y" and simultaneously solve the 3 equations for a, b, and c.

Putting (0,9):

We substitute a=b/6 into this equation and solve for b:

Thus, "a" will be:

Thus, we have a = 1, b = 6, c = 9

The given point is (-3,2). It is required to identify the quadrant in which the point is located.

Notice that the x-coordinate of the point is negative, while the y-coordinate is positive.

This implies that the point is located in the second quadrant.

Plot the point on the coordinate plane:

The answer is quadrant II.

From the trapezoid,

x + ( 31 + 38 ) + y = 180 ------------ equ 1

x + y + 69 = 180

x + y = 180 - 69

x + y = 111 .................... equ 2

Also, x + 31 + 90 = 180

x + 121 = 180

x = 180 -121

x = 59.....................equ 3

put x = 59 in equ 2 ,

59 + y = 11

Let's write the equation for every function:

Since f(x) passes through (0,-1) and (5,14), the equation will be given by:

Using the point-slope equation:

Using the same procedure for g(x):

Now we have our functions:

Part A:

We can translated f(x) k units up in order to get g(x) ( A vertical translation)

Or, we can translated f(x) k units to the left in order to get g(x) ( A horizontal translation)

We can see a graph of the functions:

Where the red function is f(x) and the blue function is g(x).

The x-intercept and the slope Set y=0 giving 0=10x+3000 x=300010=300 seconds, or precisely 5 minutes.

Y is described as being "above ground" in height. He will get into problems if he descends below ground!

In regard to time x, the right hand side (RHS) has negative 10x, which decreases 3000. Consequently, the starting height must be 3000 feet. Moreover, it is the y-intercept.

The number of feet that the parachutist will descend in x seconds must be the -10x. It is also the graph's gradient or slope.

The graph's intersection with the x-axis indicates that y=0 and y is the height above the earth.

The point when the item is about to strike the ground is therefore the x-intercept.

The rate of descent, or slope, remains constant as time (x) passes.

The rate of fall is actually a extremely rounded value In metric form, I believe the speed to be 9.81 meters per second per second, to two decimal places.

It is approximately 32.2 feet per second per second in imperial form.

becasue  i solved in. my phone and my teacher said its right

Answer

The answer = -25

Explanation

As long as we note that

(+) × (-) = (-)

(-) × (+) = (-)

We can easily solve this,

(-25) + (42) + (-62) + (20)

= -25 + 42 - 62 + 20

= 17 - 62 + 20

= -45 + 20

= -25

The area of the inner section is 320 cm^2

The area of the bigger section is 96 cm^2 (bigger trapezoid)

The area of the smaller trapezoid is 80 cm^2

Here, we want to calculate the area of each section of the frame

As we can see, there are 5 sections of the frame

The inner section represented by a rectangle and 4 adjoining shapes looking like a trapezoid

The inner part of the frame is a rectangle that measures 16 cm by 20 cm

Now, for the trapezoid part, we have 2 different sets

The first two set, has a longer length 28 cm, and shorter length of 20 cm

The second set has a longer length of 24 cm and a shorter length of 16 cm

Now, to get the area of the trapezoid, we need the height of the trapezoid which is called the width in this case. This measure corresponds to a measure of 4 cm on the two sets

Mathematically, the area of a trapezoid is;

Where a is the longer length and b is the shorter length with h representing the width of 4 cm

For the bigger trapezoid, we have;

For the smaller trapezoid, we have;

Then, we have the inner section as;

p' = 25% = 0.25

Let's find the probability that a sample proportion will over- or under-estimate the parameter by more than 5%.

Here, the error is:

Errror = |p' - p| = |0.25 - 0.30| = |-0.05| = 0.05

This error is not surprising.

Now, to find the probability that a sample proportion will be over or underestimate more than 5% will be:

Hence, we have:

Using the standard normal distribution table, we have:

NORMSDIST(-1.09) =0.1379

NORMSDIST(1.09) = 0.8621

Hence, we have:

p(z<-1.09) = 0.1379

p(z>1.09) = 1 - 0.8621 = 0.1379

p(z<-1.09) + p(z>1.09) = 0.1379 + 0.1379 = 0.2758

Therefore, the probability is 0.2758.

In order to identify bounds on the real zeros of this polynomial, first we need to find tendencies about the signal of f(x)

We know that the two term with highest degree is being multiplied by a positive coefficient. Therefore, we can initially conclude the f(x) tends to positive infinite as x grows either positive or negative.

We can check that, for x = -2, the first term is 272, and the remaining thermis togheter are given by:

Then for x < -2, and for also for x > 2, we can state for sure that f(x) remains always positive.

Then, any possible roots must lies in the intervel (-2,2)

e can also chegck that, for x = 1, f(x) = -103, and, for x = -1, f(x) = -1.

The second inequality is y > -5x + 10. To graph this inequality we have to draw a dashed line y = -5x + 10 and since the inequality represents the values of y greater than the line, the shaded area is the one above the line.

Two points on the line are the y-intercept (0, 10) and the x-intercept (2, 0).

To answer this question, we need to know that we can represent, algebraically, two consecutive positive odd numbers as follows:

Then, if we have that the product of both consecutive positive odd numbers is 323, then:

Now, we have:

We have here a polynomial (a quadratic equation) that we can solve using the quadratic formula:

Then, we have that:

• a = 4

• b = 8

• c = -320

Then

Then, the solutions are:

Therefore, we have two solutions for n, n = 8 or n = -10.

If we substitute the value of n = 8 in the original equations, we have:

If we use the negative value for the solution, we obtain:

Since these two numbers are negative, we have that the appropriate solution is n = 8.

Therefore, we have that the smaller of the two numbers is 17:

The numbers 17 and 19 are consecutive positive odd numbers.

In summary, we have that the smaller number is 17.

to determine the lcm of 6 and 8, express these numbers as the product of prime numbers:

6 = 2x3

8 = 2x2x2

the same factors determine the lcm. In this case, the factors
