Answer:

The 180 degrees angle.

Step-by-step explanation:

We can start by dividing 1260 / 360 = 1080. Therefore, a 1080 degrees angle would be coterminal with 360.

Now we take 1260 - 1080, to see how many degrees we have left, this gives us: 180, therefore, the angle between 0 and 360 that is coterminal with 1260 degrees is the 180 degrees angle.

Travel time when Carlos traveled at 52 miles/hr = t1
Travel distance when Carlos traveled at 52 miles/hr = 52 t1

Travel time when Maria traveled at 54 miles/hr = t2
Travel distance when Maria traveled at 54 miles/hr = 54 t2

total time 
t1 + t2 = 4.1 

total distance
52 t1 + 54 t2 = 217

( t1 + t2 = 4.1 ) * 52
52 t1 + 52 t2 = 213.2

Subtract last 2 equations
2 t2 = (217-213.2)
2 t2 = 3.8
t2 = 1.9

t1 = 2.2

Hours Maria driven = 2.2 hours

We are given with the total number of library books of 66. 18 of these 66 books were classified as fiction while the remaining are non-fiction books. The ratio of non-Fiction to fiction can be determined by first finding out the number of non-fiction books. that is 66-18 or 48 books.The ratio then is 48/18 or 8/3.

Uno dos tres sorry I don't understand

you pay x for ten laps an you pay y for every additional lap you just multiply y by seven an add x

so all an all your answer would be (B)

hope this helps!!!

B- 1/2 the books are science books. You have to add the two fractions and subtract that from one.

The main contours of English colonization in the seventeenth century was that English colonization was funded by proprietary provinces operating with land grants, or charters, from the English monarchy.

What are you choices?

A product increases its value because of the imposition of  tax. For example, a medicine that cost $1 can be bought possibly at $1.4 because of the value added tax. To determine the original bill without tax, the equation is $7.95/1.06. This is equal to $7.5.

40% off of 45$ would leave you with 27$

The resultant force is the sum of all forces positioned at different directions and placed in a specific angle. In this case, we can take the short way to answer this problem. we use the calculator and shift the mode to complex to add 100<50 and 50<160. the answer is 95.29<79.54. The magnitude is 95.29 pounds and the angle is 79.54°.

C. the rate of travel i believe.

 Statement 1:
Supplementary angles 2 angles whose measures have a sum of 180 degrees.Linear pair  are 2 adjacent angles whose non common sides are opposite rays.
Statement 2:
This statement states that the two lines are perpendicular.

The triangle made by Susan, the flagpole and her line of sight is similar to the triangle formed between Susan and the mirror. In this case, using the theorem of similar triangles, the equation is x/(72+12)= 5/12 where x is the height of the pole. The height of the pole is 35 feet.

Do you happen to know what the width of the rectangle is?
because the formula to find the area of a rectangle is

A=wl
A is the area
w is the width
l is the length

The formula log b C= log a C/ log ab for logarithms can be used for simplifying equations or deriving equations from one to another. This is a common logarithmic expression that can be simplified to solve calculus equations under integral and differential applications, for example.

To find x, the answer of the equation 5 / 6 x+7=12- 5 / 12x, we group the x and the numerics. Hence, the equation becomes 5/6 x -5/12 x = 12-7. we simplify this to 5/12 x = 5. We find x by multiplying 5 to 12 and dividing the product by 5. Hence the answer to this problem is 12.

The students' profit from each shirt=$10.99-$3.99=$7.00.
To break even, they need to sell $280/$7=40 shirts.
The correct answer is C

volume of a cylinder= πr²h
where r is radius and h is height.

here,
3.14 x 2.5²in x h = 170in²
3.14 x 6.25in x h = 170in²
19.625 x h = 170in²
h = 170in²/19.625
h = 8.66242038...in

corrected to the nearest hundredth, it is 8.66 inches

To quickly calculate this problem, we multiply the square root of two to 19 inches and check if the product is equal to 20.62 inches. Square root of two comes from the pythagorean theorem assuming the angle of the corners is 90 degrees. In this case, the answer is 26.87 inches which is greater than 20.62 inches. This means the shape of the room is not a square. 

The answer is;
Am+m3
Your welcome
I thought no it's right

1/sqrt8 = 4(m+2)

1/sqrt8 = 4m +8

1 = (4m +8)*sqrt8

1 = 4m*sqrt8 +8sqrt8

sqrt8 = 2sqrt2

1 - 16sqrt2 = (8sqrt2)*m

m = (1 - 16sqrt2)/8sqrt2 

m = (1 -16sqrt2)*sqrt2 / (8*2)

m = (sqrt2 -32)/16

hope this will help you

Volume of the cone is 23 in^3. = (1/3)pi r^2 h.
Given r=1, pi=3.14
so we have
(1/3)(3.14)1^2 h=23
h=23/((1/3)(3.14)1^2)
=21.97
=22 in. (approx.)
