Answer- Yes it is a right triangle.
You can use the Pythagorean Theorem.
( a^2 + b^ = c^2 ) and replace a with 10, b with 24, and c with 26 and the equation will be balanced on both sides.

(10^2 + 24^2 = 26^2)
(100 + 576 = 676 )

A stadium has two sections, A and B.
Alekssandra [29.7K]
ANSWER: a=12 b=15
Explanation: (look at work below)

4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15

If the diameter of a circle is 18 feet, which is closest to the circumference
MAXImum [283]

If the diameter of the circle is 18 feet, the circumference of the circle is 56.55 feet.

The circumference of a circle or ellipse in geometry is its perimeter. That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.

The diameter of a circle is 18 feet.

D = 18 feet

Now, the radius of the circle is half the diameter of the circle.

Therefore,

Diameter = 2 × Radius

Radius = Diameter / 2

D = 2r

r = D / 2

r = 18 feet / 2

r = 9 feet

Now, the circumference of a circle is given as:

Circumference = π × diameter

Circumference = π × 2r

Circumference = 2πr

Circumference = 2 × π × 9 feet

Circumference = 2 × 3.14159 × 9

Circumference = 56.55 feet

a skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $61. A season ski pass costs $300. The s

D=61d+30d=91d, 

S=300+30d

S<D

300+30d<91d

300<61d

d>4.91  Since days are integers,

The skier would have to go at least 5 days to make the season pass less expensive than using the daily pass.

Please help me this is the last question of the day.
FrozenT [24]
So 5.10 is 100% and 0.57 is x%
percent means parts out of 100
5.10/100%=0.57/x% since they are equal (exg 2/4=3/6)
5.10/100=0.57/x
multipy both sides by x/0.57 to clear fraciton
(5.1x)/57=1
multiply both sides by 57 to get rid of the denomeator (bottom number

5.1x=57
divde both sides by 5.1
x=11.1765
increase of 11.2%
( an easy way is (0.57/5.1) times 100)
