Answer:

1/2 or 2/4

Step-by-step explanation:

The total amount of pieces is 4. The dot is at the second piece. Therefore, it is at 2/4. We can simplify 2/4 to 1/2 by dividing both the numerator and the denominator by 2.

I hope this helped and please mark me as brainliest!

Paul lands a home mortgage of $58,200 at a

qwelly [4]

Answer:

$72,100

Step-by-step explanation:

To calculate the total principal+interest payment, you can use the formula to find the future value:

FV=PV(1+i)^n

FV= Future value

PV= Present value= $58,200

i= Interest rate= 7.40%

n= Number of periods of time= 3 years

Now, you can replace the values on the formula:

FV=58,200*(1+0.0740)^3

FV=58,200*(1.0740)^3

FV=72,100

According to this, the answer is that the total principal + interest payment will be $72,100.

1. What is an equation of the line through (3, 12) with slope = 3?

mafiozo [28]

Answer:

see below

Step-by-step explanation:

We can use point slope form

y - y1 = m(x-x1)

where m is the slope and ( x1,y1) is a point on the line

y-12 = 3(x-12)

If we want it in slope intercept form

Distribute

y-12 = 3x-36

Add 12 to each side

y-12+12 = 3x-36+12

y = 3x-24

Answer:

For a: The answer is $2.3\times 10^1$

For b: The answer is $8.0\times 10^{-6}$

For c: The answer is 127.6

For d: The answer is $4.66\times 10^4$

Step-by-step explanation:

Significant figures are defined as the figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.
All non-zero numbers are always significant. For example: 654, 6.54 and 65.4 all have three significant figures.
All zero’s between integers are always significant. For example: 5005, 5.005 and 50.05 all have four significant figures.
All zero’s preceding the first integers are never significant. For example: 0.0078 has two significant figures.
All zero’s after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures.
All zeroes used solely for spacing the decimal point are not significant. For example : 8000 has one significant figure.

Rule applied for the addition and subtraction is:

The least precise number present after the decimal point determines the number of significant figures in the answer.

Rule applied for the multiplication and division is:

The number of significant digits is taken from the value which has least precise significant digits.

For the given options:

Option a: (2.7)(8.632)

The given problem is a multiplication one.

$\Rightarrow (2.7\times 8.632)=23.3$

Here, the least precise significant digits are 2. So, the answer is $2.3\times 10^1$

Option b: (3.600 x 10^-4) / 45

The given problem is a division one.

$\Rightarrow \frac{(3.600\times 10^{-4})}{45}=0.08\times 10^{-4}$

Here, the least precise significant digits are 2. So, the answer is $8.0\times 10^{-6}$

Option c: 2.365 + 125.2

The given problem is an addition one.

$\Rightarrow (2.365+125.2)=127.565$

Here, the least precise significant digits after decimal is 1. So, the answer is 127.6

Option d: (4.753 x 10^4) - (9 x 10^2)

The given problem is a subtraction one.

$\Rightarrow (4.753\times 10^4)-(9\times 10^2)=(4.753\times 10^4)-(0.09\times 10^4)=4.663\times 10^4$

Here, the least precise significant digits after decimal are 2. So, the answer is $4.66\times 10^4$
