If y equals 7 when x equal 2/3, so when x =7/3 the y is equal to 14/7

If y varies inversely with x, this means that the product of x and y is a constant. So if we know that y = 7 when x = 2/3, then we can set up the equation: x*y = k, where k is the constant.

Substituting the known values we get: (2/3)*7 = k.

So we know that k = 14/3

Now, we can use this value of k to find the value of y when x = 7/3.

x*y = k

(7/3)*y = 14/3

y = 14/7

So, when x = 7/3, y = 14/7

Step-by-step explanation:

The height of her pear tree is 20 inches

First subtract 46 from 26 to get 20. So 20+26=46inches

x=20

Step-by-step explanation:

you know how to transform an equation ?

you need to apply the same operating to both sides of the equation. always. otherwise the equality relation is destroyed.

x + 26 = 46

to get to "x = ..." the "+ 26" is in the way.

clearly we need to subtract 26. but we need to do it on both sides.

x + 26 - 26 = 46 - 26

x = 20

that simply means the last tree is 20 in.

it is 26 in shorter than 46 in (fig tree).

that's all there is to it.

The values of the expression are given by the inequality below:

11/3 < 5/x + 2 < 9/2

Here we want to find the possible values of the expression:

5/x + 2

Where we have the restriction:

2 < x < 3

Notice that x is on the denominator, so when x takes the largest value x = 3, we will have a lower bound for the expression:

5/3 + 2 = 5/3 + 6/3 = 11/3

When x takes the smallest value, we will get the upper bound:

5/2 + 2 = 5/2 + 4/2 = 9/2

Then the possible values of the expression are:

11/3 < 5/x + 2 < 9/2

The probability of being born on a Tuesday is= 18/343

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The likelihood that an event will occur increases with its probability.

A straightforward illustration is tossing a fair (impartial) coin.

The coin is fair, thus the outcomes "heads" and "tails" are equally likely; the likelihood of "heads" is equal to the likelihood of "tails"; and because there are no other conceivable outcomes, the likelihood of either "heads" or "tails" is 1/2 (which is also an acceptable spelling).

Hence, The probability of being born on a Tuesday is= 18/343.

$2094.28 interest will she pay by the time the loan is repaid.

What is compounded monthly?

Theoretically, continuously compounded interest means that an account balance continuously earns interest as well as reinvesting that interest into the balance so that it too earns interest.

As we know the formula of per month installments

[tex]E.M.I = \frac{P*r*(1+r)^n}{(1+r)^n^-^1}[/tex]

By putting the value of P (loan applied for)=$5500

r (Monthly rate of interest)  [tex]= \frac{6.8}{12*100}[/tex]

n = number of monthly installments = 10 × 12 = 120

[tex]E.M.I = \frac{5500*(\frac{6.8}{12*100} )(1+\frac{6.8}{1200} )^1^2^0}{(1+\frac{6.8}{1200} )^1^2^0-1}\\ E.M.I= \frac{5500*0.00567*1.971}{1.971-1}\\ E.M.I = \frac{61.461}{0.971} \\E.M.I = 63.29[/tex]

E.M.I.=$63.29

Total Installments of loan =120

Therefore total amount paid against loan = $63.39 × 120 = 7594.28

So interest paid = 7594.28 - 5500= $2094.28

Hence, $2094.28 interest will she pay by the time the loan is repaid.

Therefore , the solution of the given problem of interest rate comes out to be $271.94 you will be depositing every month.

The original capital is multiplied by the interest rate, the loan term, and other factors to calculate simple interest. A simple return is equal to the principal plus interest hrs. This method of calculating interest is the simplest. The most typical method is to calculate it as a fraction of the principal amount. For instance, he was only liable for paying his portion of the interest if he acquired $100 from a buddy and agreed to repay the money on 5% interest. $x (0.05) = $5. When you make loans or lend money, you both have to pay interest. Interest is frequently determined as a percentage of a loan.

Here,

Given  :  interest = 9%

time  =35 years

The prime factorization of the radicand 2 is 9√15.

A number can be expressed as the product of its prime components through the process of prime factorization. A number with precisely two elements, 1 and the number itself, is said to be a prime number.

As an illustration, let's use the number 30. We know that 30 = 5 × 6, but 6 is not a prime number. The number 6 can further be factorized as 2 × 3, where 2 and 3 are prime numbers. Therefore, the prime factorization of 30 = 2 × 3 × 5, where all the factors are prime numbers.

Given that,

x= 3√135

Solving the equation further using the rule √A*B = √A*√B

x= 3√9*15

x= 3√9*√15

x=3*3*√15

According to BODMAS

The region inside cardioid r = 1 + cos(θ) and outside the circle r = 3 cos(θ) is equal to [tex]\frac{\pi}{4}[/tex]

Now, According to the question:

We will first draw both of them on the same plane and then find their point of intersection. Then using the given information, we will shade the region whose area we have to find.

The point of intersection of  r = 1 + cos(θ) and  r = 3 cos(θ)

1 + cos(θ)  = 3 cos(θ)

1 = 2 cos(θ)

=> cos(θ) = 1/2

=> θ = [tex]cos^-^1[/tex][tex]\frac{1}{2}[/tex]

=> θ = ±[tex]\frac{\pi }{3}[/tex]

So, two curves intersect at θ = ± [tex]\frac{\pi }{3}[/tex]

Area of the cardioid,

[tex]A_1 = \int\limits^\pi _\frac{\pi }{3} {\frac{1}{2}(1+cos\theta)^2 } \, d\theta= \frac{1}{2} \int\limits^\pi _\frac{\pi }{3} (1+cos^2\theta+2cos\theta) } \, d\theta=\frac{1}{2}[/tex]

          [tex]\int\limits^\pi _\frac{\pi }{3} {(1 + \frac{cos2\theta+1}{2} +2cos\theta)} \, d\theta[/tex]

 => [tex]A_1 = \frac{1}{2}[\theta+\frac{1}{2}(\frac{sin2\theta}{2} +\theta)+2sin\theta ]^\pi _\frac{\pi }{3}[/tex]

=> [tex]A_1= \frac{1}{2}[\frac{3\pi }{2}+0+0-\frac{\pi }{2}-\frac{\sqrt{3} }{8} -\sqrt{3} ][/tex]

=> [tex]A_1= \frac{1}{2} [\pi +\frac{-9\sqrt{3} }{8} ]\\\\A_1 = \frac{\pi }{2} - \frac{9\sqrt{3} }{16}[/tex]

Area of the circle,

[tex]A_2 = \int\limits^\frac{\pi }{2} _\frac{\pi }{3} {\frac{1}{2}(3cos\theta)^2 } \, d\theta \\\\A_2 = \frac{9}{2} \int\limits^\frac{\pi }{2} _\frac{\pi }{3} \frac{cos2\theta+1}{2}d\theta\\ \\A_2 = \frac{9}{4}[\frac{sin2\theta}{2}+\theta ]^\frac{\pi }{2}_\frac{\pi }{3}[/tex]

[tex]A_2 = \frac{9}{4}[0+\frac{\pi }{2} -\frac{\sqrt{3} }{4} -\frac{\pi }{3} ][/tex]

[tex]A_2=\frac{9}{4}[\frac{\pi}{6}-\frac{\sqrt{3} }{4} ][/tex]

[tex]A_2= \frac{3\pi }{8}-\frac{9\sqrt{3} }{16}[/tex]

Area of the shaded region,

[tex]A = A_1-A_2[/tex]

[tex]A = \frac{\pi }{2} - \frac{9\sqrt{3} }{16} - \frac{3\pi }{8}+\frac{9\sqrt{3} }{16}[/tex]

[tex]A = \frac{\pi }{8}[/tex]

This is the area of the shaded region in the first and the second quadrant. We see that by symmetry, the area of the shaded region in the first and the second quadrant is equal to the area of the shaded region in the third and the fourth quadrant.

So, the total area is 2 ×[tex]\frac{\pi}{8}[/tex] = [tex]\frac{\pi}{4}[/tex]

Answer:

First account: $16,000

Second account: $4,000

Step-by-step explanation:

Let x be the amount Christine invested in the 8% account and y be the amount she invested in the 10% account. We know from the problem that:

x + y = $20,000 (the total amount she had to invest)

0.08x + 0.1y = $1920 (the total amount of interest she received)

We can use the first equation to solve for one variable in terms of the other.

x = $20,000 - y

Now we substitute this expression into the second equation:

0.08($20,000 - y) + 0.1y = $1920

Solving for y:

0.08x + 0.1y = $1920

0.08($20,000 - y) + 0.1y = $1920

1,600 - 0.08y + 0.1y = $1920

-0.08y = -320

y = $4,000

Now, we know that Christine invested $4,000 in the 10% account, we can use the first equation again to find out how much she invested in the 8% account:

x + y = $20,000

x + $4,000 = $20,000

x = $16,000

So Christine invested $16,000 in the 8% account and $4,000 in the 10% account
