Isaac's parents borrow $3600.00 from the bank for new appliances for their kitchen. The simple interest rate is 9% per year. How much interest will they have to pay if it takes them 4 years and 3 months to repay the loan?

Based on the number of dice rolled, the probability of getting the sum of 6, and 4 and 6 or 4 can be found to be:

Probability of getting sum of 6:

(1 and 5) (2 and 4) (3 and 3) (4 and 2) ( 5 and 1)

= 5 / (6 x 6)

= 5 / 36

The number of sums of 4 are:

= (1 and 3), (2 and 2), (3 and 1)

= 3 / (6 x 6)

= 1 / 12

The probability of getting sums of 6 and 4 are:

= (5 + 3) / (6 x 6)

= 8 / 36

= 2 / 9

These events are mutually exclusive because they cannot roll a sum of 6 or 4.

Answer:

180=x+42

collect like terms

x=180-42

x=138

Answer:

Step-by-step explanation:

(i) Find the value of y when x = - 2

(ii) See the graph attached

(iii) The axis of symmetry is the vertical line passing through the vertex, which is x + 1 = 0 or x = - 1.

This is also reflected on the attached graph.

(iv) From the graph it is visible that in the given interval the function is decreasing, so the value at x = - 4 is the maximum and the value at x = - 2 is minimum:

These two points too are given on the same graph.

(v) There ate two x-intercepts, the one on the right is the larger one.

It is (0.732, 0), marked on the graph.

(vi) This function is the standard form of the given:

With the positive leading coefficient of 1, it has a minimum value but no maximum. The minimum of this function is at its vertex, which is (- 1, 3) as per graph.

(vii) The function y = x² + 2x is the translation of the given function up by two units.

So its minimum value is 2 units greater:

The inverse function of one-to-one function f(x)= 7x - 2 is [tex]f^{-1}=\frac{x}{7}+\frac{2}{7}[/tex].

The graphs of f and [tex]f^{-1}[/tex] are symmetric with respect to the line defined by y = x.

Given that:-

f(x)= 7x - 2

Let f(x) = y

Hence,

[tex]f^{-1}(y)=x[/tex]

Hence, we can write,

y = 7x - 2

y + 2 = 7x

x = y/7 + 2/7

[tex]f^{-1}(y) = y/7 + 2/7[/tex]

Replacing y by x, we get,

[tex]f^{-1}(x) = x/7 + 2/7[/tex]

Hence, the inverse function of f(x) is [tex]f^{-1}(x) = x/7 + 2/7[/tex].

The graph of inverse is always the mirror image of the function's graph in the line y = x. It is because they're basically 100% similar but in reverse just like you in a mirror.

Answer: 57.14 km/hr

Step-by-step explanation:  if an hour is divided into quarters it will be in increments of 15 minutes, since  one hour is 60 minutes.  60 minutes divided by 5 is 15 minutes.  

So 1 hour and 38 minutes is rounded off to 1 hour and 45 minutes.

this is 1 hour + 3/4 hour = 1 3/4 hour.  This is same as 1.75 hour

3/4 is .75

speed divided by the time will give the average speed.

100km/1.75hours  = 57.14 km/per hour

Answer:

(a)  1 hour 45 min

(b)  57.1 km/h (nearest tenth)

Step-by-step explanation:

Given information:

[tex]\large\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]

[tex]\begin{aligned}\sf \dfrac{1}{4}\;hour &= \sf 1 \; hour \div 4 \\& = \sf 60 \;mins \div 4\\& = \sf 15 \; mins\end{aligned}[/tex]

Therefore, the nearest ¹/₄ hours either side of the given time is:

1 h 38 min 45 sec is 8 min 45 sec more than 1 hour 30 min.

1 h 38 min 45 sec is 6 min 15 sec less than 1 hour 45 min.

Therefore, the nearest ¹/₄ hour to the given time is:  

1 hour 45 min = 1.75 min (in decimal form)

Substitute the given distance and the rounded time (in decimal form) into the formula and solve for speed:

[tex]\begin{aligned} \implies \sf Speed & =\sf \dfrac{Distance}{Time}\\\\& = \sf \dfrac{100}{1.75}\\\\& = \sf 57.1\;km/h\;(nearest\;tenth)\end{aligned}[/tex]

The system of equations for the given conditions in question includes equation: 3.40 = 0.05x + 0.1y + 0.25z, and 2x = z. and we have 2 nickels, 23 dimes, and 4 quarters.  

What is system of equations?

A system of equations is a collection of some equations with one or more numbers of variables. Systems of equations have solutions that are either the variable mappings that satisfy each component equation or the intersections of all of these equations.

Let the quantities of nickels, dimes, and quarters are x, y, and z respectively.

We know that, 1 nickel = $0.05, 1 dime = $0.1, and 1 quarter = $0.25

So, the values of nickels, dimes, and quarters would be value of one times total quantity.

Nickels = 0.05x, dimes = 0.1y, and quarters = 0.25z

As given in the question, the total value is 3.40

So, we get equation:

3.40 = 0.05x + 0.1y + 0.25z

Also it is given that there are twice as many nickels than quarters.

2x = z

Combining above two equations

3.40 = 0.05x + 0.1y + 0.25(2x)

3.40 = 0.05x + 0.1y + 0.5x

3.40 = 0.55x + 0.1y

Lets put 2 in place of x, we get y

(3.40 - 1.1)0.1 = y

y = 23.

Now, putting values of x, y in equation to get value of z

3.40 = 0.05(2) + 0.1(23) + 0.25z

3.40 = 0.1 + 2.3 + 0.25z

(3.40 - 2.4)/0.25 = z

z = 4

Therefore, we have 2 nickels, 23 dimes, and 4 quarters.

The problem is that the $100 bill was fake, so at this point the total amount that he loses is:

Step-by-step explanation:

x^3 + 8x^2 + 11x = -800

I just plugged it into my calculator

The principal amount is $693.33.

Simple interest is a quick and simple approach to figure out how much money has accrued interest. Interest is always applied to the original principal amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount.

The formula is

Simple Interest = P x R x T/100

Given:

Interest = 78

Rate= 7.5%

Time= 1 and half year = 1.5 year

Now, Simple Interest= P x R x T / 100

                             78 = P x 7.5 x 1.5 / 100

                             7800= P x 11.25

                             P = 7800/11.25

                              P = 693.33

The linear equation 20x + 35(60-x) = 1500 can be solved to find the number of tickets.

What is an equation?

An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its related terms in various languages may have somewhat different definitions; for example, in French, an equation is described as including one or more elements, but in English, an equation is any well-formed formula that includes two expressions linked by an equals sign.

Let the number of advance tickets sold = x

And then, the number of same-day tickets sold = 60 - x

Then, the equation formed is

20x + 35(60-x) = 1500

=> 20x + 2100 - 35x = 1500

=> -15x = 1500 - 2100

=> x = -600/ -15 = 40

Hence, the number of advance tickets sold = 40

And the number of same-day tickets sold = 60 - 40 = 20
