The alloy of copper will be 600 ounces.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Let us represent

Number of ounce of 30% copper = x

Hence, our Equation will be given below:-

x × 30% + 200 × 70% = (x + 200) × 40%

0.3x + 140 = (x + 200)0.4

0.3x + 140 = 0.4x + 80

Collect like terms

0.4x - 0.3x = 140 - 80

0.1x = 60

x = 60/0.1

x = 600 ounces

Therefore the alloy of copper will be 600 ounces.

Leah have to put down 13% of the total money in order to pay for the home.

The amount of money a person borrows from a bank to buy a house is termed as Home Loan.

It is given that

Leah wants to buy a home for $380,000

The amount of money he can get from bank is $ 330,600

The amount of money Leah needs to have

= $ 380000 - $ 330600 = $49400

The percentage Leah have to put down in order to pay for the home is

=($49400 /$380000 ) * 100%

= 0.13 * 100 %

= 13%

Therefore Leah have to put down 13% of the total money in order to pay for the home.

Multiply through by x - 3

Then factor the result

4*(x - 3) / (x - 3) = x*(x - 3)

4 = x * (x - 3 )                          Remove the brackets

4 = x^2 - 3x                            Subtract 4 from both sides

4-4 = x^2 - 3x - 4                    Simplify

0 = x^2 - 3x- 4

This factors

0=(x - 4)(x + 1)

Answer

x - 4 = 0

x = 4

x+ 1 = 0

x = - 1

The system of inequalities of the graph is (a) y > x² + 2x - 3 and y > 2x + 3

The complete question requires that we determine the system of inequalities of the graph (the graph is attached)

Going by the list of options, the equation of the quadratic curve is:

y = x² + 2x - 3

From the graph, we can see that:

The above means that the inequality is greater than i.e. >

So, we have:

y > x² + 2x - 3

The above eliminates options (b) and (c)

From the graph, we can see that the straight line has a positive slope, a dotted line and the upper part is shaded.

The linear inequality in option (a) has the above characteristics.

So, the inequality is:

y > 2x + 3

Hence, the system of inequalities of the graph is (a) y > x² + 2x - 3 and y > 2x + 3

The water level increases by 0.608 meters per minute when the water is 3.5 m deep

The given parameters are:

The relationship between the radius and height is:

r/h = 3/7

Make r the subject

r = 3h/7

The volume of a cone is;

[tex]V = \frac 13\pi r^2h[/tex]

This gives

[tex]V = \frac 13\pi (\frac{3h}{7})^2h[/tex]

Expand

[tex]V = \frac{3h^3}{49}\pi[/tex]

Differentiate

[tex]V' = \frac{9h^2}{49}\pi h'[/tex]

Make h' the subject

[tex]h' = \frac{49}{9\pi h^2}V'[/tex]

When the water level is 3.5.

We have:

[tex]h' = \frac{49}{9\pi * 3.5^2}V'[/tex]

Also, we have:

V' = 4.3

So, the equation becomes

[tex]h' = \frac{49}{9\pi * 3.5^2} * 4.3[/tex]

Evaluate the products

[tex]h' = \frac{210.7}{346.36}[/tex]

Evaluate the quotient

h' = 0.608

Hence, the water level increases by 0.608 meters per minute

After 85 minutes of calls, there are $27.25 left on the card.

A linear equation in slope-intercept form is:

y = a*x + b

Where a is the slope.

If the line passes through two points (x₁, y₁) and (x₂, y₂) the slope is:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

In this case, we know that the line passes through the points (22, 36.7) and (52, 32,20)

(points of the form (time, dollars)).

So the slope is:

[tex]a = \frac{32.2 - 36.7}{52 -22} = -0.15[/tex]

The linear equation is then:

y = -0.15*x + b

To find the value of b, we use the point (22. 36.7)

36.7 = -0.15*22 + b

36.7 + 0.15*22 = b = 40

Then the linear equation is:

y = -0.15*x +40

The amount remaining in the credit card after 85 minutes is given by evaluating the above equation in x = 85.

y = -0.15*85 + 40 = 27.25

This means that after 85 minutes of calls, there are $27.25 left on the card.

Answer:

35.1% chance of going sledding

Step-by-step explanation:

45% chance of snow on Friday

Convert percentage to decimal form (divide by 100)

45% = 0.45

78% chance of sledding if it snows

Convert percentage to decimal form (divide by 100) to multiply

78% = 0.78

Multiply to find the probability of both occurring

0.78 * 0.45 = 0.351

Convert back into a percentage (multiply by 100)

0.351 = 35.1% chance of sledding

The  probability that more than 562 drivers is 0.9328

It is a branch of mathematics that deals with the occurrence of a random event.

Given: p = 0.60

n = 900

Let X denote the number of drivers that wear a seat belt,

P(X > 562)

[tex]\mu[/tex] = n*p = 900(0.60) = 540

[tex]\sigma^{2}[/tex]= n*p*(1-p)

=900*0.60*0.40

=216

P(X >562) = Pr( Z > 1.4976)

                = 0.9328

Hence, the probability that more than 562 drivers is 0.9328
