Assuming he has the money to make the down payment, my classmate will borrow 90% of the home price.

A down payment is the upfront payment or an initial portion of the total purchase price of expensive property.

It is required that the buyer of a mortgaged property deposits this initial portion before taking the mortgage for the balance.

Mortgage period = 30 years

Interest rate = 3.5% fixed

Down payment = 10%

Balance (Mortgage) = 90% (1 - 10%)

The answer is the Second Number Line.

The exact time is 93 days

The interest is  $20.38

The maturity value is  $1020.38

The interest is a function of the time, amount borrowed and the interest rate.

Interest = amount borrowed x time x interest rate

Time = June 9 - March 8 = 93 days

Answer:

The first one: 12/13  > 36/30

Step-by-step explanation:

The first one would be correct as 12/13 is less than 36/30.

To explain why 13/17 is actually less than 24/28, see below:

So when comparing fractions, we must follow steps.

Step One: convert mixed numbers to a fraction, if there are any

There are not mixed numbers to compare, so we can move to the next step.

Step Two: find the least common denominator of the two fractions

Least common denominator = 476

Check out our least common denominator calculator for help on finding this.

Step Three: rewrite each fraction to an equivalent fraction using the denominator 476

To do this, start by dividing 476 by the denominator of the first fraction. Next, multiply the result by the numerator to find the new numerator. To rewrite, put the new numerator over 476. Repeat this for the second fraction

364/476                              408/476

Step Four: compare the numerators

At this point, to compare the fractions, we can simply compare the numerators to see which is larger

364<408

Step Five: rewrite each fraction as the original fraction

13/17<24/28

Therefore, the first statement (12/13 > 36/30) is true.

Answer:

  12/13 < 36/30

Step-by-step explanation:

There are many ways to compare numbers. One way is to compare them to some value that lies between. Another is to consider their difference from a value that does not lie between.

In the first fraction, 12 < 13, so the value of the fraction is less than 1:

  12/13 < 1

In the second fraction, 36 > 30, so the value of the fraction is greater than 1:

  1 < 36/30

Then the order of the fractions is ...

  12/13 < 1 < 36/30

  12/13 < 36/30 . . . . . the given order is True

We notice the difference between numerator and denominator is 4 in each case, so we can write each fraction as a difference from 1:

  (13/17) vs (24/28)

  = (1 - 4/17) vs (1 -4/28) . . . . . fractions rewritten

  = -4/17 vs -4/28 . . . . . . . . . subtract 1 from both

The first fraction, 4/17, has a smaller-value denominator, so its magnitude is larger than that of the fraction 4/28. In other words, the ordering of these fractions is ...

  -4/17 < -4/28

  1 -4/17 < 1 -4/28 . . . . . . add 1 to both sides

  13/17 < 24/28 . . . . . the given order is False

__

Additional comment

One sort of "no brainer" way to compare the fractions is to multiply them by the product of their denominators. This looks like "cross multiplication" where each numerator is multiplied by the opposite denominator. As long as you keep the numerators in the same relative places, the comparison symbol will be the correct one for the fractions.

  12/13 vs 36/30   ⇒   (12·30) vs (13·36)   ⇒   360 < 468

The left fraction is smaller than the right fraction.

Similarly, ...

  13/17 vs 24/28   ⇒   (13·28) vs (17·24)   ⇒   364 < 408

The left fraction is smaller than the right fraction.

Here, we have used the fractions "as is." In each case, the fraction on the right could be reduced, possibly making the comparison easier.

Given the radius of 50 miles and the line joining the cities at (0, 56) and (58, 0), the transmitter signal can be picked during 59.24 miles of the drive.

Radius of broadcast of the transmitter = 50 miles

Location of starting point = 56 miles north of the transmitter

Location of destination city = 58 miles east of the transmitter

Therefore we have;

Slope of the line joining the two cities

= 56 ÷ (-58) = -0.966

Which gives the equation of the line as follows;

y = -0.966•x + 56

The equation of the circle is;

[tex] {x}^{2} + {y}^{2} = {50}^{2} [/tex]

[tex] {x}^{2} + { ( - 0.966x + 56)}^{2} = {50}^{2} [/tex]

1.933156•x^2 - 108.192•x + 636 = 0

Which gives;

Therefore;

When x = 6.67, we have;

When x = 49.29, we have;

The requried, numerator of the simplified sum is 4x + 6. The option is correct.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve. For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property

The given expression is x/(x²+3x+2) + 3/(x+1). To make the denominators the same, we need to factor the denominator of the first fraction:

x/(x+1)(x+2) + 3/(x+1)

Now we can add the two fractions by finding a common denominator, which is (x+1)(x+2):

x/(x+1)(x+2) + 3(x+2)/(x+1)(x+2)

Simplifying the numerators, we get:

x + 3x + 6 / (x+1)(x+2)

Combining like terms in the numerator, we get:

4x + 6 / (x+1)(x+2)

Therefore, the simplified expression is (4x+6)/(x+1)(x+2).

So, Number of maths textbooks sold = x-62

The textbook store sold a combined total of 460 physics and math textbooks in a week.

So, the equation becomes,

(x-62)+x = 460

⇒ x-62+x = 460

⇒ 2x-62 = 460

⇒ 2x = 460+62

⇒ 2x = 522

Given that the line passes through the point (-6, -5) with a slope of 6, we can plug these values into the equation to find the y-intercept (b).

Using the point-slope form of the equation:

y - y₁ = m(x - x₁)

Substitute (-6, -5) and the given slope (m = 6):

y - (-5) = 6(x - (-6))

y + 5 = 6(x + 6)

Now, let's simplify the equation:

y + 5 = 6x + 36

Answer:

96 sq. inch

Step-by-step explanation:

rectangle has 24 inches × 8 inches dimensions

Hence, Area of Rectangle,

A1=24×8

=192 sq. inch

We, know triangle with base 24 inches and height 8 inches has area exactly half of the rectangle's.

ie. A2=½(24×8)

=96 sq. inch

This was for unshaded region. Then remaining half area is for shaded region.

A1-A2=A

ie. 192-96=96 sq. inch

The area of the shaded region is 96 square inches.

To find the area of the shaded region, we need to subtract the area of the triangle from the area of the rectangle.

The area of a rectangle is calculated by multiplying its length by its width. In this case, the rectangle has a length of 24 inches and a width of 8 inches, so its area is 24 inches * 8 inches = 192 square inches.

The area of a triangle is calculated by multiplying its base by its height and dividing the result by 2. In this case, the triangle has a base of 24 inches and a height of 8 inches, so its area is (24 inches * 8 inches) / 2 = 96 square inches.

Now, to find the area of the shaded region, we subtract the area of the triangle from the area of the rectangle:

Shaded Area = Area of Rectangle - Area of Triangle

= 192 square inches - 96 square inches

= 96 square inches

Therefore, the area of the shaded region is 96 square inches.
