What is it? I don't understand it or know it.​

Answer:

The original number is 572.

Step-by-step explanation:

Let the 3 digit number by xyz.

Where x is the hundreds digit, y is the tens digit and z is the units digit.

Hence, the digit is (100x + 10y + z).

From the question, the tens digit equals to the sum of the hundreds digit and the units digit.

That is,

y = x + z ...... (1)

Also, from the question, the hundreds digit of this number is 3 more than the units digit.

That is,

x = z + 3 ...... (2)

Also, from the question, If the digits were reserved, the new number is 11 less than half of the original number

If the digit were reversed, that is xyz becomes zyx. Then, the new number is (100z + 10y + x).

the new number is 11 less than half of the original number

That is,

(100z + 10y + x) + 11 = 1/2(100x + 10y + z)

This becomes

200z + 20y + 2x + 22 = 100x + 10y + z

200z - z +20y -10y +2x - 100x = -22

199z + 10y -98x = -22 ...... (3)

Solving the equations simultaneously,

Put the value of x in equation (2) into equation (1)

x = z + 3 ...... (2)

y = x + z ...... (1)

That is,

y = (z+3) + z

y = 2z + 3 ...... (4)

Put the value of y in equation (4) into equation (3)

199z + 10y -98x = -22

199z + 10(2z +3) -98x = -22

199z + 20z + 30 -98x = -22

219z -98x = -22-30

219z -98x = -52 ...... (6)

Put the value of x in equation (2) into equation (6)

219z -98(z+3) = -52

219z -98z -294 = -52

121z = -52 + 294

121z= 242

z = 242/121

∴ z = 2

Put the value of z into equation (2)

x = z + 3

x = 2 + 3

∴ x = 5

Put the values of z and x into equation (1)

y = x + z

y = 5 + 2

∴ y = 7

Hence, x = 5, y = 7 and z = 2.

Recall that the original number is 100x + 10y + z.

100x + 10y + z = 100(5) + 10(7) +2 = 500 + 70 + 2 = 572

Hence, the original number is 572.

Answer:

Height of ball after 3rd bounce = 8 inch

Step-by-step explanation:

Given:

Height of ball dropped = 27 inch

Bounces = 2/3  of previous height

Find:

Height of ball after 3rd bounce

Computation:

Height of ball after 1st bounce = 27[2/3]

Height of ball after 1st bounce = 18 inch

Height of ball after 2nd bounce = 18[2/3]

Height of ball after 2nd bounce = 12 inch

Height of ball after 3rd bounce = 12[2/3]

Height of ball after 3rd bounce = 8 inch

Note: Your question sounds a little unclear and incomplete. I assume you want to get the idea about the graph of 3|x|. My answer may still clear your concept about the graphs.

Answer:

The graph of y=3|x| is attached below.

Step-by-step explanation:

Given the function

[tex]y=3\left|x\right|[/tex]

Determining the domain:

We know that the domain of a function is the set of input or argument values for which the function is real and defined.

The function has no undefined points nor domain constraints. Therefore, the domain is:

[tex]-\infty \:<x<\infty \:[/tex]

Determining the range:

We also know that the range of a function is the set of values of the dependent variable for which a function is defined.

[tex]\mathrm{The\:range\:of\:an\:absolute\:function\:of\:the\:form}\:c|ax+b|+k\:\mathrm{is}\:\:f\left(x\right)\ge \:k[/tex]

[tex]k=0[/tex]

[tex]f\left(x\right)\ge \:0[/tex]

Thus,

[tex]\mathrm{Range\:of\:}3\left|x\right|:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}[/tex]

Determining the x-intercept and y-intercept:

Answer:

Se obtuvo $ 448 de ganancia por la venta de donas.

Se obtuvo $ 280 de ganancia por la venta de bolillos.

Step-by-step explanation:

1) ¿Cuanta ganancia se obtuvo en la venta de donas?

La ganancia es el producto del porcentaje producido de donas, expresado como razón, el precio unitario de la dona y el total producido de panes. Es decir:

[tex]C = \frac{40\,donas}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{dona} \right)[/tex]

[tex]C = 448\,USD[/tex]

Se obtuvo $ 448 de ganancia por la venta de donas.

2) ¿Cuanta ganancia se obtuvo en la venta de bolillos?

La ganancia es el producto del porcentaje producido de bolillos, expresado como razón, el precio unitario del bolillo y el total producido de panes. Es decir:

[tex]C = \frac{25\,bolillos}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{bolillo}\right)[/tex]

[tex]C = 280\,USD[/tex]

Se obtuvo $ 280 de ganancia por la venta de bolillos.

In this exercise we have to use the knowledge of finance to calculate the profit.

1) $ 448 profit was made from donut sales.

2) A profit of $ 280 was obtained from the sale of cupcake.

1)The profit is the product of the percentage produced of donuts, expressed as a ratio, the unit price of the donut and the total produced of breads. That is to say:

[tex]C= (\frac{40}{100} )*(140)*(8)= 448 USD[/tex]

$ 448 profit was made from donut sales.

2) The profit is the product of the percentage of cupcake produced, expressed as a ratio, the unit price of the cupcake and the total amount of bread produced. That is to say:

[tex]C= (\frac{25}{100}) *(140)*(8)= 280 USD[/tex]

A profit of $ 280 was obtained from the sale of cupcake.

Answer:

The value if x is 20

Step-by-step explanation:

Hope this helps :)

The value of the variable x is 20. Then the correct option is A.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

If the two chords of the circle intersect at a point, then the product of the segments of the chord will be equal.

We know that the product of (x - 5) & (x - 8) and (x - 5) & (x) will be equal. Then we have

(x - 5) · (x - 8) = (x - 11) · x

Simplify the equation, then the value of the  variable x will be

(x - 5) · (x - 8) = (x - 11) · x

x² - 13x + 40 = x² - 11x

2x = 40

x = 20

Thus, the value of the variable x is 20.

Then the correct option is A.

Answer:

87,000,000

Step-by-step explanation:

The millionths place in 87,365,219 starts at 7.

87,365,219

The rhyme that I learned for this when I was younger was: 5 and above give it a shove, 4 or below, let it go.

The number 3 after the 7 is less than five so you would have to let it go. So, everything after 7 would become zeros and you would not round 7 up.

Your final answer becomes 87 million

Hope this helps! :)

After rounding 87,365,219 to the nearest million, the number is 87000000.

Focus on the digit in the next position to the right for rounding a number to the nearest million. If the number is 5, round up and if the number is 4 or less than 4, round down.

Consider the following figure.

The hundred thousand place number is 3 which is less than 4.

Thus, round down to 87000000.

Therefore, after rounding 87,365,219 to the nearest million, the number is 87000000.

[tex]\frac{3}{5}[/tex]  ↔ sinC

[tex]\frac{16}{15}[/tex] ↔ cosC × tanD

[tex]\frac{4}{5}[/tex] ↔ sinD

Step-by-step explanation:

In the given triangle CBD

∵ ∠B is a right angle

∴ CD is the hypotenuse

→ We can use the trigonometry ratios

∵ sinC = opposite side of ∠C ÷ hypotenuse

∴ sinC = [tex]\frac{BD}{DC}[/tex]

∵ BD = 3 and CD = 5

∴ sinC = [tex]\frac{3}{5}[/tex]

∵ cosC = adjacent side of ∠C ÷ hypotenuse

∴ cosC = [tex]\frac{BC}{DC}[/tex]

∵ BC = 4 and CD = 5

∴ cosC = [tex]\frac{4}{5}[/tex]

∵ tanC = opposite side of ∠C ÷ adjacent side of ∠C

∴ tanC = [tex]\frac{BD}{BC}[/tex]

∵ BD = 3 and BC = 4

∴ tanC = [tex]\frac{3}{4}[/tex]

∵ sinD = opposite side of ∠D ÷ hypotenuse

∴ sinD = [tex]\frac{BC}{DC}[/tex]

∵ BC = 4 and CD = 5

∴ sinD = [tex]\frac{4}{5}[/tex]

∵ cosD = adjacent side of ∠D ÷ hypotenuse

∴ cosD = [tex]\frac{BD}{DC}[/tex]

∵ BD = 3 and CD = 5

∴ cosD = [tex]\frac{3}{5}[/tex]

∵ tanD = opposite side of ∠D ÷ adjacent side of ∠D

∴ tanD = [tex]\frac{BC}{BD}[/tex]

∵ BD = 3 and BC = 4

∴ tanD = [tex]\frac{4}{3}[/tex]

Answer:

x ≤ $30

Step-by-step explanation:

Including the $15 for flowers, there is a budget of $45. Josh cannot spend more than $30 on a gift.

x can be less than or equal to $30

The inequality for the $x of gift x≤ 30.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

For example, In the 12U Softball division, Olivia gets chosen. What is Olivia's age?

Olivia's age is unknown to you since the word "equals" is missing. However, because you are aware that she should be under or equal to 12, you can write Olivia's Age ≤ 12.

Given:

Total amount spend on gift = $45

price of flower= $15

So, the amount of gift only is

=45- 15

=$30

Thus, Josh can only spend $30 for the gift not more than that.

Hence, the inequality for the $x of gift

x≤ 30
