seraphim [82]

The amount of the down payment and the fixed rate mortgage is $35000 and $9625.

According to the statement

We have given that the

Thomas osler is buying a house selling for $175,000 And we have to find the amount of the down payment and the monthly payment.

So, The down payment is :

percentage of the down payment is 20%

So,

Amount = 20/100*175000

Amount = 35,000$

And the percentage of the fixed rate mortgage with 5.5%

So,

Amount = 5.5/100*175000

Amount = $9625.

This the amount of the down payment with the given percentage and with the fixed rate mortgage.

So, The amount of the down payment and the fixed rate mortgage is $35000 and $9625.

If the surface area of a cube is increased by a factor of 2 (so that the new surface area is twice the size of the original surf
Mariana [72]

Answer:2.828

Step-by-step explanation:

Given

Surface area of a cube is increased by a factor of 2

Let the original surface area be A

such that new surface area is 2A

for volume we need to know new radius

6(a')^2=2\times 6r^2

where r'=new radius

r=original radius

a'=\sqrt{2}a

New volume(V')=(a')^3=(\sqrt{2}a)^3

V'=2\sqrt{2}a^3

Original volume=a^3

\frac{V'}{V}=\frac{2\sqrt{2}a^3}{a^3}

V'=2\sqrt{2}V=2.828V

After working 80 hours at his job, Tyshawn earned a total of $1080. How much does Tyshawn earn
bogdanovich [222]

The amount  Tyshawn earn per hour is $13.5

<h3>Ratio and proportion</h3>

Fractions are written as a ratio of two integers

If after working 80 hours at his job, Tyshawn earned a total of $1080, then;

80 hrs = $1080

In order to calculate the amount earned per hour

Amount per hour = 1080/80

Amount per hour = $13.5

Hence the amount  Tyshawn earn per hour is $13.5

Which values of m and b will create a system of equations with no solution? choose 1 options.
hichkok12 [17]

Answer:

The graph of a linear equation is a straight line.  The "solution" to a system of two linear equations is the point where the two lines cross.  If the two lines are parallel, they never cross; hence parallel lines have no solution.  Two lines are parallel if they have the same slope (the m value in y = mx+b).  One of your equations is y = -2x + (you left the y-intercept out).  The slope is -2.  So any line with a slope of m = -2 will be parallel to this line and will not cross it.  The second line also needs a different value of b, the y-intercept.  Otherwise it is the same line and every point is a solution.  So if your equation is:

 

y = -2x + 1

 

Then any equation of the form y = -2x + b, b≠1 will create a system with no solution.  Hence the values of m and b are m = -2, b ≠ 1.
