If bc+ad=b solve for a (please show work)

Answers

Answer 1

Answer:

a = [tex]\frac{b-bc}{d}[/tex]

Step-by-step explanation:

Given

bc + ad = b ( subtract bc from both sides )

ad = b - bc ( isolate a by dividing both sides by d )

a = [tex]\frac{b-bc}{d}[/tex]

Bill is making accessories for the soccer team. He uses 777.35 inches of fabric on headbands for 32 players and 3 coaches. He also uses 301.76 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Answer:

Fabric used on a headband for each player = 22.21 inches

Fabric used on a wristband for each player = 9.43 inches

Step-by-step explanation:

Let fabric used on each headband = [tex]h[/tex] inches

Let fabric used on each wristband = [tex]w[/tex] inches

Number of players for which headband is made = 32

Fabric used on 32 players = 32[tex]h[/tex] inches

Number of coaches for which headband is made = 3

Fabric used on 3 coaches = 3[tex]h[/tex] inches

As per question statement:

Total fabric used on headbands = 777.35 inches

[tex]32h + 3h = 777.35\\\Rightarrow 35h = 777.35 inches \\\Rightarrow h = 22.21\ inches[/tex]

Number of players for which wristband is made = 32

As per question statement:

Fabric used on wristbands = 301.76 inches

[tex]32w = 301.76\\\Rightarrow w = 9.43\ inches[/tex]

Therefore, the answer is:

Fabric used on a headband for each player = 22.21 inches

Fabric used on a wristband for each player = 9.43 inches

Considerando las siguientes variables a = ancho y l = longitud, determina su valor, si se sabe que se cuenta con un rectángulo que tiene como perímetro 35 metros, y se sabe que el doble de su ancho es igual a 3 veces su longitud.

Answers

Answer:

La longitud = 7 metros

La anchor = 10.5 metros

Step-by-step explanation:

La fórmula para el perímetro de un rectángulo es

P = 2L + 2W

L = longitud

A = ancho

P = 35 metros

se sabe que el doble de su ancho es igual a 3 veces su largo.

2A = 3L

Ancho = 3L / 2 = 1.5L

Sustituimos 1.5L por W

35 = 2 L + 2 (1.5 L)

35 = 2L + 3L

35 = 5 litros

L = 35/5

L = 7 metros

Por lo tanto, la longitud = 7 metros

Recuerda

A = 1.5 L

A = 1.5 × 7

A = 10.5 metros

La anchor = 10.5 metros

A circle has a diameter of 32 m. What is its circumference?
Use 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer.

Answers

Answer:

[tex]C=32(3.14)=100.48\text{ meters}[/tex]

Step-by-step explanation:

We know that the circle has a diameter of 32 meters.

And we want to find its circumference.

The circumference of a circle is given by the formula:

[tex]C=\pi d[/tex]

Where d is the diameter.

So, we will substitute 32 for d and we will use 3.14 for π. Hence, our circumference will be:

[tex]C=32(3.14)=100.48\text{ meters}[/tex]

Answer:

100.48 m

Step-by-step explanation:

C=2(3.14)r

C=2(3.14)(16)

C= 100.48 m

4.A trapezoid with a perimeter of 30 units is
graphed on a coordinate grid. The trapezoid is
dilated by a scale factor of 0.3 with the origin as the
center of dilation. If (x,y) represents the location of
any point on the original trapezoid, which ordered
pair represents the coordinates of the corresponding
point on the resulting trapezoid?
A. (30x, 30y)
B. (X - 0.3, y +0.3)
C. (0.3x, 0.3y)
D. (x + 0.3, y +0.3)

Answers

Answer:

It would be (x0.3,y0.3). C is the answer

Step-by-step explanation:

Because if you actually read it, it already gave you the answer which is the scale factor of 0.3

so that would lead to (x0.3,y0.3)

A video posted on the internet is becoming very popular, and the total number of views is increasing by 40% every hour. If the video currently has 74,300 views, how many views will it have in 9 hours?

Answers

Answer:

74304 approx.

Step-by-step explanation:

Step one:

given data

current view of the video is marked at =74300

the rate of increase is 40%

let the number of hours be x

and let the total views be y

hence the linear function for the total is

y=0.4x+74300

Required is the value of y when x=9

Step two:

substitute x=9

y=0.4(9)+74300

y=3.6+74300

y=74303.6

y=74304 approx.

Answers

Answer: 32/27 Equation: 8/9 x 4/3

Steps:

For dividing fractions remember the phrase “keep, change, change”

So keep the first fraction, change the division sign to a multiplication sign, and change the second fraction to its reciprocal.

8/9 x 4/3

Multiply the numerators together. Next, multiply the denominators together.

8 x 4 = 32

An art teacher mixes 20 ounces of yellow paint with 8 ounces of red paint. How many ounces of yellow paint would she need to mix with 18 ounces of red paint to maintain the same proportion

Answers

30. Answer if u place the equation into a fraction: example 20/8 yellow over red. Next let’s put the other amount into a fraction, we don’t know yellow so for the fraction we will put x: x/18. For our next step we will then cross multiply 20 by 18 and 8 by x getting 8x=360 from there you divide for x getting 45 yellow.

The total amount of yellow paint she needs to mix with 18 ounces of red paint to maintain the same proportion is 45 ounces and this can be determined by using the unitary method.

Given :

An art teacher mixes 20 ounces of yellow paint with 8 ounces of red paint.

The following steps can be used in order to determine the total amount of yellow paint:

Step 1 - The unitary method can be used in order to determine the total amount of yellow paint she needs to mix with 18 ounces of red paint to maintain the same proportion.

Step 2 - Let the total amount of yellow paint she needs be 'x'.

Step 3 - So, the value of 'x' can be calculated as:

[tex]x = \dfrac{18}{8}\times 20[/tex]

Step 4 - Simplify the above expression.

[tex]x = 45\;{\rm ounces}[/tex]

The total amount of yellow paint she needs to mix with 18 ounces of red paint to maintain the same proportion is 45 ounces.

To win a sum, a duck with a green star on the underside must be selected

The number of ducks with this is 4 out of 75

The probability of selecting one is 4/75

The expected value of selecting is ;

4/75 * 10 = 0.5333

The cost of selecting a duck is $1

The probability that a duck that wins will not be selected is 71/75 which at a price of $1 is 0.9467

Since the price to lose and the amount to win is not the same, then the game is not fair

The Statue of Liberty stands as perhaps the most iconic symbol of our nations largely immigrant past and its European heritage in particular.Under the watchful gaze of this imposing monument, lives converged. Between 1892 and 1954, over 12 million immigrants passed through the processing facility on Ellis Island. Many of those people left homes across Europeparticularly England, Ireland, the German and Russian empires, and Scandinavian countriesto escape famine, political and economic oppression, or in search for greater opportunities in America. Upon crossing Americas shores, European immigrants spread across the North American continent, altering its physical and cultural landscape along the way. These experiences are often told through the treasured European American narrative of the melting potwhere diverse groups traveled to a New World, where they peopled a nation and forged a uniquely American identity. However, these immigrants arrived on a continent already populated by indigenous nations who possessed their own complex political, economic, and cultural systems. The ensuing encounters between these diverse groups serve as some of the foundational moments in American history.
