Answer:

Sale price= $26.25

Step-by-step explanation:

Giving the following information:

Selling price= $35

Discount rate= 25%

To calculate the sale price of the sweater, we need to use the following formula:

Sale price= selling price*(1 - discount rate)

Sale price= 35*(1 - 0.25)

Sale price= 35*0.75

Sale price= $26.25

Answer:

x = 2

Step-by-step explanation:

2x−3-x+4=3

combine like terms:

x + 1 = 3

x = 2

The equation is true for the value of x = 2.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is as given below.

2x − 3 - x + 4 = 3

We have to operate the like terms together.

Here 2x and x are like terms and 3 and 4 are like terms.

(2x - x) - 3 + 4 = 3

x - 3 + 4 = 3

x + 1 = 3

Subtracting 1 on both sides,

x = 3 - 1

x = 2

Hence the equation is true for x = 2.

Answer:

(-2.5, 1) and (0.5, 5)

Step-by-step explanation:

The main idea is to divide the line into four segments.

so you find the midpoint between (-4, -1) and (2, 7), which is (-1, 3).

then you find the midpoint again between (-4, -1)  (-1, 3) and (2, 7) (-1, 3), which is (-2.5, 1) and (0.5, 5).

Answer:

x = 116°

Answer:

Part A

1.5 seconds

Part B

By substitution and factorization because h = 0 at ground level

Step-by-step explanation:

Part A

The height from which the soccer player heads the ball, h = 6 feet

The initial velocity of the ball, v = 20 ft./s

The height of the ball in feet, h = -16·t² + 20·t + 6

From the given equation of the ball, we have;

At the initial height, t = 0, from the given equation, h = 6

At the  ground level,  the height, h = 0, therefore, we get;

0 = -16·t² + 20·t + 6

Factorizing using a graphing calculator gives;

0 = 2 × (-8·t² + 10·t + 3) = -2 × (8·t² - 10·t - 3) = -2 × (2·t -3)·(4·t + 1)

∴ (2·t -3)·(4·t + 1) = 0

t = 1.5 or t = -1/4 = -0.25

Therefore;

The time it takes the ball to hit the ground, t = 1.5 seconds.

Part B

The method used in solving the given quadratic equation is by plugging in the value of 'h' as h = 0 in the given equation and factorizing the result because at ground level, the height, h = 0.

Answer:

1/6

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability of choosing dimes twice = total number of dimes / total number of coins

At first pick = 4/9

because there is no replacement, dimes and total coins reduce by 1 and

second pick = 3/8

4/9 x 3/8 = 1/6

By definition of the focus of a parabola, the coordinates of the focus of the parabola - 8 · (x - 5) = (y + 1)² are represented by the point F(x, y) = (3, - 1). (Correct choice: A)

The standard equation of the parabola with an horizontal axis of symmetry is presented below:

[tex]x - h = \frac{1}{4\cdot p}\cdot (y - k)^{2}[/tex]     (1)

Where:

The coordinates of the focus is described by the following expression:

F(x, y) = (h + p, k)

If we know that h = 5, k = - 1 and p = - 2, then the coordinates of the focus are:

F(x, y) = (5 - 2, - 1)

F(x, y) = (3, - 1)

By definition of the focus of a parabola, the coordinates of the focus of the parabola - 8 · (x - 5) = (y + 1)² are represented by the point F(x, y) = (3, - 1). (Correct choice: A)

Step-by-step explanation:

Answer:

The time Lamar will catch up to Fran is 50.26 mins and they would have walked 2.5 km each.

Step-by-step explanation:

Given;

total distance walked by both Fran and Lamar, d = 5 km = 5,000 m

speed of Fran, = 45 m/min

speed of Lamar, = 50 m/min

Let the time Lamar catch up to Fran = t (mins)

At the time "t" Lamar would have walked a distance of 50(t),

At the time "t" Fran would have walked a distance of 45(t + 5)

The total distance they walked; d = 50t  +  45(t + 5)

5000 = 50t  +  45(t + 5)

5000 = 50t  + 45t + 225

5000 - 225 = 95t

4775 = 95t

t = 4775/95

t = 50.26 mins

The distance walked by Frans: = 45 (50.26 + 5)

                                                    = 2487 m

The distance walked by Lamar: = 50 (50.26)

                                                    = 2513 m
