Answer 1

Answer: so the qustion is which of these shos the commutative property
the commutative property of multiplication is
note:ab=a times b=a(b)

so a(bc)=(ab)c

first choice: 4.1 times (6.2 times 5.0)=(4.1 times 6.2) times 5.0
this is obviously the right answer A is the answer

B
2.7 times 1=2.7 this is the identity property of multiplicaiton, anything times 1= same thing

C 7.2 times 0=0 this is the 0 property of multiplication

D. 8.5 times 0.4=0.4 times 8.5
this is the equality property

the answer is A

Roderigo has just finished paying back his $8,575 unsubsidized Stafford loan, which he took out to fund his four-year degree. The loan had a duration of ten years and an interest rate of 7.1%, compounded monthly. Roderigo will allow interest capitalization. If Roderigo made monthly payments to pay off his loan, how much interest did he pay in total? Round all dollar values to the nearest cent.

Answers

Answer:

Roderigo will pay $7353.80 in interest.

Step-by-step explanation:

Interest capitalization means the interest earned is added to the principle amount so first we will use compound interest formula.

Compound interest formula is :

$p(1+(r)/(n) )^(nt)$

p = 8575

r = 7.1% or 0.071

n = 12

t = 4

Putting the values in formula we get;

$8575(1+(0.071)/(12) )^(48)$

Solving this we get;

Amount = $11381.94

For the next part we have EMI formula as:

$(p* r*(1+r)^(n) )/((1+r)^(n)-1 )$

p = 11381.94

r = $7.1/12/100=0.005917$

n = $12*10=120$

$(11381.94*0.005917*(1+0.0059147)^(120) )/((1+0.005917)^(120)-1 )$

= $(11381.94*0.005917*(1.005917)^(120) )/((1.005917)^(120)-1 )$

EMI = $132.74

Now total payments made in 120 months (10 years) = $132.74*120=15928.80$ dollars

Now, interest paid = $15928.80-8575=7353.80$ dollars

Hence, Roderigo will pay $7353.80 in interest.

Find the distance between the two points (6, -2), (1, -5)

Answers

Answer:

5.83095

Step-by-step explanation:

X1= 6

X2= 1

Y1 = -2

Y2= -5

Distance Formula = √(X2-X1)²+ (Y2-y1)²

Step 1. calculate (X2-X1)²

(1 - 6)2 = 25

Step 2. calculate (Y2-Y1)²

(-5 - -2)2 = 9

Step 3. calculate √25 + 9

= 5.83095

How are rational expressions related to rational numbers?

Answers

A rational expression is the same way that any integer is also a rational number. You can stick to any polynomial in the numerator of a fraction and put "1" in the denominator.

During a four-week period, you worked the following hours: Week 1- 363 /8 hr; Week 2- 411 /4 hr; Week 3- 401 /2 hr; Week 4- 383 /8 hr What is the average number of hours you worked in one week?A. 393 /8 hr
B. 381 /4 hr
C. 391 /8 hr
D. 383 /4 hr

Answers

Total hours worked in 4 weeks = (363/8) + (411/4) + (401/2) + (383/8)
= (363 + 822 + 1604 + 383)/8
= 3172/8 hours
= 793/2
Then
Average hours worked in a 4 weeks = (793/2) hours
So
Average hours worked in 1 week = 793/(2 * 4) hours
= 793/8 hours
So the average number of hours worked in 1 week is 793/8 hours.
