Answer:

$277,419

Step-by-step explanation:

Relevant Data provided as per the question is

Net amount = 50,000

Closing cost = 8,000

Loan amount = 200,000

Commission percentage = 7%

According to the given situation, the calculation of the minimum contract price is shown below:-

[tex]Minimum\ contract\ price = \frac{(Net\ amount\ +\ Closing\ cost\ +\ Loan\ amount) }{Remaining\ percentage}[/tex]

[tex]= \frac{(50,000 + 8,000 + 200,000)}{(100\% - 7\%)}[/tex]

[tex]= \frac{258,000}{93\%}[/tex]

= $277,419

Therefore for calculating the minimum contract price we simply applied the above formula.

Answer:

A. England = 56000000

B. 1.046 * 10^7

C. 9.7 to 2sf

Step-by-step explanation:

A. England = 5.60*10000000

=56000000

B. Wale = 3.14*1000000 = 3140000

Scotland = 5.44*1000000 = 5440000

Northern Ireland = 1.88*1000000 =1880000

Total = 10460000

In standard form =1.046*10^7

C. Total population as at 2018 = 66460000

expected population by 2041 = 72900000

increase or change = (72900000 - 66460000) = 6440000

% change = (6440000/66460000)*100

= 0.0969003912 * 100

= 9.69003912

= 9.7 to 2sf

Answer:

Step-by-step explanation:

Given the function f(x) = 12, the function is only a constant with no degree. For a function to have roots, it must have at least degree of 1. Let us write the function f(x) = 12 in terms of x

f(x) = 12x⁰

From the function above it can be seen that the introduction of x⁰ can not in any way affect the function of x because x⁰ will return 1.

From the function, it can be seen that the highest power of the variable x is zero. This means that the function has no roots.

Hence, there are no real zeros of the function.

Answer:

500 and 5,000

Step-by-step explanation:

The value of the first 5 is five hundred (500)

The value of the second is five thousand (5,000)

The place value of 5 in the number 25,578 is 500 and 5,000.

The value of each digit in a number is known as the place value. The 5 in 5,006 signifies 5 thousand, or 5,000, while the 5 in 350 represents 5 tens, or 50. Children must learn that while a digit can have the same value, its value changes depending on where it appears in the number.

A number is a numerical unit of measurement and labeling in mathematics. The first examples are the numbers 1, 2, 3, and 4.

The place value of 5 in the number 25,578 will be calculated as below:-

The value of the first 5 is five hundred 500.

The value of the second is five thousand 5,000.

Therefore, the place value of 5 in the number 25,578 is 500 and 5,000.

Answer:

Step-by-step explanation:

The distance between two points can be found by using the formula

We can now substitute 15 in as d, to see how much this will cost.

[tex]20\cdot15 + 7\\\\300+7\\\\307[/tex]

So the total cost will be $307.

Since $307 is more than $250, she does not have enough money.

Answer:

(2x+9)  ^3

Step-by-step explanation:

 (((8 • (x3)) +  729) +  (22•33x2)) +  486x

 ((23x3 +  729) +  (22•33x2)) +  486x

Factoring:  8x3+108x2+486x+729  

 8x3+108x2+486x+729  is a perfect cube which means it is the cube of another polynomial  

 In our case, the cubic root of  8x3+108x2+486x+729  is  2x+9  

 Factorization is  (2x+9)3

Answer:

128 markers.

Step-by-step explanation:

7 x 8 =  56

12 x 6 = 72

72+ 15 = 87

Hadley and Delaney therefore bought 128 markers all in total.

Hope I helped ! :))))))

The amount of markers Hadley and Delaney bought in all is equal to 128 markers.

Given  the following data:

To determine the amount of markers Hadley and Delaney bought in all:

First of all, we would determine the total number of marker in each box.

For Hadley:

[tex]Hadley = 7 \times 8[/tex]

Hadley = 56 markers

For Delaney:

[tex]Delaney = 6\times 12[/tex]

Delaney = 72 markers

Now, we can find the total markers:

[tex]Total \;markers = Hadley + Delaney\\\\Total \;markers = 56+72[/tex]

Total markers = 128 markers

Using Point Slope formula :

[tex](y - y_1) = \frac{(y_2 - y_1)}{(x_2 - x_1)} (x - x_1)[/tex]

[tex](y - 4) = 5(x - 3)[/tex]

[tex]y = 5x - 11[/tex]

Answer:

The point slope formula is : y-y₁ =m(x-x₁), so first u need to find the value of slope.

Step-by-step explanation:

finding the value of slope:

slope(m)= y₂-y₁ ÷ x₂-x₁

              = -1-4 ÷ 2-3

               = 5

now finding equation;

y-y₁=m(x-x₁)

y-4 = 5(x-3)

11=5x - y

0= 5x - y -11

therefore equation of line in point slope is : 5x-y-11=0

Answer: They are both right triangles so you can use the Pythagorean Theorem to get the length of the missing side

Answer: a. ​is always an upper tail test.

Step-by-step explanation:

The chi-square goodness-of-fit test is a test to check whether the sample comes from the population with the expected distribution or not.

If the observed frequency is close to the expected frequency, then the square of the deviations will be small. The square of the deviation is divided by the expected frequency to get the weighted frequencies.

If the sum of these weighted squared deviations is large is then it creates a doubt for the distribution claimed other wise not. Therefore, the chi-square goodness-of-fit test is always a right tail test.

Hence correct option is "a. ​is always an upper tail test. "

Your question has been heard loud and clear.

M1 = 2kg , M2=2kg , V1=10m/s V2=5m/s

Total momentum before collision = M1V1+M2V2 = 2*10 + 2*5 = 30kgm/s  

Now , by law of conservation of momentum ,

Total momentum before collision = total momentum after collision

Therefore , total momentum of objects before and after collision = 30kgm/s
