If each acute angle of a parallelogram measures 59 degrees, then what is the masure of each obtuse angle?

There are two acute angles in a parallelogram and 2 obtuse angles. This means that there is 360-(59*2) degrees left, or 242 degrees left to split between the two obtuse angles. Divide 242 by 2 to get 121 degrees.

A parallelogram has to have a total of 360 degrees in angles, so we take 59 x 2 to get 118, we then subtract 118 from 360, 360 - 118 = 242, we then divide by two because a parallelogram has 2 obtuse angles, giving us an answer of 121 degrees. Hope this helps

If a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month, what

OLEGan [10]

Answer:

$97.15.

Step-by-step explanation:

We have been given that a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month. The interest rate of credit card is 3.35% monthly.

We will use interest formula to solve our given problem.

$I=PrT$ , where,

$I=\text{Interest}$ ,

$P=\text{Principal amount}$ ,

$r=\text{Interest rate in decimal form}$ ,

$T=\text{Time}$

Let us convert our given interest rate in decimal form.

$3.35\%=\frac{3.35}{100}=0.0335$

Upon substituting our given values in interest formula we will get,

$I=2,900*0.0335*1$

$I=2,900*0.0335$

$I=97.15$

Therefore, the monthly interest charge at the end of the 1st month will be $97.15.

Ty has 230 pages of text to read in the next three days. if he averages 25 pages every 1 1/4 hours, how many hours is he going t

sineoko [7]

Answer:

11.5 hours

Step-by-step explanation:

25 pages every 75 minutes (1 1/4)

Thats means 1 page every 3 minutes (divide 25 and 75 by 25 to get this)

230 pages would mean 690 minutes (times the 3 by 230)

690/6 = 11.5

Perimeter of given figure is equal to :

Perimeter of square - side length + quarter Circumference of the circle

that is :

$\qquad \sf \dashrightarrow \:(10 \times 4) - (5 + 5) + \dfrac{2 \pi r}{4}$

$\qquad \sf \dashrightarrow \:40- 10 + \dfrac{3.14 \times 5}{2}$

$\qquad \sf \dashrightarrow \:30+ \dfrac{15.7}{2}$

$\qquad \sf \dashrightarrow \:30 + 7.85$

$\qquad \sf \dashrightarrow \:37.85 \: \: units$

So, the required perimeter is 37.85 units

Step 2: Simplify

[Distributive Property] Distribute negative: 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x
Combine like terms (x²): 4x² + 2y² - 3x + y² - 2x - 3y² - x
Combine like terms (y²): 4x² - 3x - 2x - x
Combine like terms (x): 4x² - 6x
