Leah ran 5/7 of a lap and Ryan ran 2/3 of a lap. Who ran farther and by how much?
Goryan [66]
Leah, she ran farther by 1/21

How you get the answer:

5/7
Multiply 7x3 to get the denominator and do the same to the numerator 5x3! Which is 15/21
To get 21 from 2/3 is to multiply 3x7 (denominator) and 2x7 (numerator) to get 14/21

15/21 > 14/21 so Leah ran farther by 1/21

Please solve this i really need this
d1i1m1o1n [39]

Answer:

a = 8 (to nearest whole number)

Step-by-step explanation:

Given:

m<B = 36°

m<C = 104°

c = 12

Required:

a

SOLUTION:

✔️First find m<A:

m<A = 180 - (104 + 36)

m<A = 40°

✔️Find a using Sine Rule:

Thus:

\frac{a}{sin(A)} = \frac{c}{sin(C)}

Plug in the values

\frac{a}{sin(40)} = \frac{12}{sin(104)}

Multiply both sides by sin(40)

\frac{a}{sin(40)} * sin(40) = \frac{12}{sin(104)} * sin(40)

a = \frac{12*sin(40)}{sin(104)}

a = 8 (nearest whole number)

Which answer describes the polynomial?
slava [35]
<span>B) Cubic Trinomial It is cubic because it goes up to the 3rd power, as seen in 3x^3. A quadratic function would only go up to the 2nd power, and a quartic function would go to the 4th. It is a trinomial rather than a binomial as it has three terms. The constant is considered as a term. It would be a binomial only if there were two terms.</span>
