Answer: he would get 1000

Step-by-step explanation:

100 x 10 =1000

Answer:

$1,000

Step-by-step explanation:

Since he makes 100 pesos in 1 hour, all you have to do is multiply 100 by 10. When multiplying a number by 10, all you do is move the decimal point back one. In this case, our decimal point is imaginary, so when we move it back one, you just add a zero at the end of the number. That gives you 1000.

Answer:

33%

Step-by-step explanation:

Prob(heads) = 1/2

Prob(either red or blue) = 2/3

So Prob( heads and red/blue) = 1/2 * 2/3

= 2/6

= 1/3   which is 33%.

:))))))) good luck

Answer: First Option is correct.

Step-by-step explanation:

Since we have given that

\begin{gathered}f(x)=-x+1,x < 0\\\\f(x)=x+1,x\geq 0\end{gathered}

f(x)=−x+1,x<0

f(x)=x+1,x≥0

If we let f(x)=y

then, y=x+1 and y=-x+1

Put x=0,

\begin{gathered}y=0+1\\\\y=1\end{gathered}

y=0+1

y=1

so, there must be coordinate on y -axis at 1.

and it must take Ist and II nd quadrant .

Hence, First Option is correct.

Answer:

The correct answer is C: [tex]t\leq 58[/tex]

Step-by-step explanation:

In order to solve this problem, start by first creating an inequality to represent the situation above. The price of the hours and the supply fee can't go over $1,500, so you can set the representative inequality as [tex]25t+50\leq 1500[/tex]. Now solve the inequality, and you will get [tex]25t+50\leq 1500[/tex] => [tex]25t\leq 1450[/tex] => [tex]t\leq 58[/tex] hrs. So C is the correct answer.

Answer:

The answer is C.t is less than or equal to 58.

Step-by-step explanation:

Let x = Number of tutoring sessions

Supplies + tutoring cost = total cost

50 + 25x = 1500

Now need to solve:

Subtract 50 from both sides and simplify

50/ + 25x - 50 = 1500 - 50

25x = 1450

Divide both sides by 25 and simplify

25x/25 = 1450/25

Therefore,

[tex]x\leq 58[/tex]

The tax on the item costs $1425.89 is 106.94175 dollars.

In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.

Given that, tax rate =7.5% and the cost of an item = $1425.89.

Here, tax = 7.5% of 1425.89

= 7.5/100 ×1425.89

= 0.075×1425.89

= $106.94175

Therefore, the tax on the item costs $1425.89 is 106.94175 dollars.

Answer:

Step-by-step explanation:

4x + 32 = 5x -22

Group like terms

32 + 22 = 5x - 4x

54 = X

X = 54

Answer:

x = 54

Step-by-step explanation:

4x + 32 = 5x - 22

5x - 4x = 32 + 22

x = 54

To clarify this,

(4 x 54) + 32 = 248

(5 x 54) - 22 = 248

Answer:

Step-by-step explanation:

Solve the following system:

{3 y + 2 x = -2 | (equation 1)

{-y + 52 x = -2 | (equation 2)

Swap equation 1 with equation 2:

{52 x - y = -2 | (equation 1)

{2 x + 3 y = -2 | (equation 2)

Subtract 1/26 × (equation 1) from equation 2:

{52 x - y = -2 | (equation 1)

{0 x + (79 y)/26 = -25/13 | (equation 2)

Multiply equation 2 by 26:

{52 x - y = -2 | (equation 1)

{0 x + 79 y = -50 | (equation 2)

Divide equation 2 by 79:

{52 x - y = -2 | (equation 1)

{0 x + y = -50/79 | (equation 2)

Add equation 2 to equation 1:

{52 x + 0 y = -208/79 | (equation 1)

{0 x + y = -50/79 | (equation 2)

Divide equation 1 by 52:

{x + 0 y = -4/79 | (equation 1)

{0 x + y = -50/79 | (equation 2)

Collect results:

Answer: {x = -4/79, y=-50/79

The factor of the quadratic equation n² + n = 56 is (n + 8)(n - 7). Then the value of the n is 7 and negative 8.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The quadratic equation will be given below.

n² + n = 56

The equation can be written as

n² + n - 56 = 0

On factorization, we have

        n² + n - 56 = 0

n² + 8n - 7n - 56 = 0

      (n + 8)(n - 7) = 0

                       n = 7, -8

The value of the n is 7 and negative 8.

the slopes are perpendicular

find a slope perpendicular to 3/2

how to find:

change the sign of the slope and flip the fraction

-2/3 is the slope

The slope of BD is -2/3.

Numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it.

Given:

BD is a diameter of circle A. If the slope of BE is 3/2.

We have to find the slope of BD.

According to given question we have

We know that the slope of a perpendicular line from the slope of a given line is obtained by taking the negative reciprocal of the slope of the given line. If the slope of the given line is [tex]m_{1}[/tex] and the slope of a perpendicular line is [tex]m_{2}[/tex] then we have

[tex]m_{2} = -1/m_{1}[/tex]

So, the slope of BD is -2/3.

Therefore, the slope of BD is -2/3.

In monthly sales would mr. gonzalez need to have $100000

Mr. Gonzalez earns his living as a salary plus commission employee, then his annual earnings can be represented by

Monthly earnings=a+bx

Where a =his annual salary (fixed),

b = the percentage of sales commission and

X =represents the volume of sales made each year.

Therefore When  Mr. Gonzalez annual salary is $18,000 and makes a commission of 4%, his annual sales that will enable him earn an annual salary of $60,000 will be equal to

$60000 = $18000 + 0.04X

$60000 - $18000 = 0.04X

$48000 = 0.04X

0.04X = $1200000

X = $48000/0.04=12000000

X=$12000000

Therefore, his monthly sales is given by his  earnings divided evenly each month is equal to

$1200000/12=$100000
