If the sum of measures of angle a and b is 280 degrees, what is the measure of angle C?

A. 80 degrees
B. 160 degrees
C. 140 degrees
D. 40 degrees

Answers

Answer:

40 degrees

Step-by-step explanation:

because angle b and angle a are vertical angles they are congruent and if they add up to 280 you just have to divide that by 2 to get the value of one of the angles

280/2=140

because angle c and angle b are supplementary they are going to add up to equal 180

180-140=40 so c=40

Answer:

40

Sarah borrows $5575 on a 2 year loan at 3% simple interest. What will be the total amount Sarah has to pay back at the end of year 2?

Answers

Answer:

$5909.50

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 5575 × 0.03 × 2 = 334.5

I = $ 334.50

The simple interest accumulated

on a principal of $ 5,575.00

at a rate of 3% per year

for 2 years is $ 334.50.

Joy has a ribbon that measures 16 yards. She cuts 9 pieces of ribbon to decorate gifts. Each piece of ribbon that Joy cuts measures 4 feet.

What is the length, in yards, of the remaining ribbon?

Answers

Answer:

4 yds

Step-by-step explanation:

So... 16 yards is 48 feet (because one yard is 3 feet so I just multiplied by 3)

and she cuts 9 pcs of ribbon each 4 feet

so it's 9 x 4 = 36

48 - 36 = 12

And 12 feet equals 4 yards

So, Joy has 4 yards of remaining ribbon

Answer:

9.3 yards

Step-by-step explanation: the exact answer is 9.3333333

12y = 8x + 29 write in slope intercept from and show all your work plz help!

Answers

Answer:

2/3x + 29/12

Step-by-step explanation:

P.S Brace yourself cause this is a lot lol :D

The slope-intercept form is

y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

First, you divide each term by 12 and simplify:

Divide each term in 12y = 8x + 29 by 12:

12y/12 = 8x/12 + 29/12

Cancel the common factor of 12:

You do this by dividing 12y/12 leaving you just with y = 8x/12 + 29/12

Then you cancel the common factor of 8 and 12:

You do this by factoring 4 out of 8x:

y = 4 (2x)/12 + 29/12

Then you cancel even more common factors:

Factor 4 out of 12:

y = 4 (2)/ 4 (3) + 29/12

Then you cancel the common factor in that dividion (which is 4) Leaving you with 2x/3 + 29/12

Finally, you rewrite the expression:

y = 2/3x + 29/12

It can be solved as follows :

[tex]\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}=\dfrac{a}{b(a-b)}+\dfrac{b}{a(b-a)}\\\\=\dfrac{a}{b(a-b)}+\dfrac{b}{-a(-b+a)}\\\\=\dfrac{1}{a-b}(\dfrac{a}{b}-\dfrac{b}{a})\\\\=\dfrac{a^2-b^2}{ab(a-b)}\\\\=\dfrac{(a-b)(a+b)}{ab(a-b)}\\\\=\dfrac{(a+b)}{ab}[/tex]

So, the solution of the given expression is equal to [tex]\dfrac{(a+b)}{ab}[/tex].
