Answer:

The equation is 4² + x² = 7²; x² = 33; x = √33

\sin( \infty )  =  \frac{ \sqrt{33} }{7}

The expression equivalent to tan 8 (theta) is

\tan( \infty )  =  \frac{ \sqrt{33} }{4}

1. Marcus bought a $40.00 tennis racket. He has a coupon for 20% off. The Sales tax where he bought the tennis racket is 6%. a.
jeka94

Answer:

$33.92

Step-by-step explanation:

First, we have to find how much the sale price for the tennis racket is before tax.

100% - 20% = 80%          Marcus has to pay 80% of the original price.

80% * 40 = .8 * 40 = 32

Marcus has to pay $32 for the tennis racket before tax.

6% = .06  (tax percentage)

.06 * 32 = 1.92 ————> tax

Add the tax with the sale price.

32 + 1.92 = 33.92

Marcus has to pay $33.92 for the tennis racket.

I hope this helped and please mark me as brainliest!

Nut B fits on Bolt B. Nut A fits on Bolt C, but does not fit on Bolt A. Bolts B and A are exactly the same. Given the scenario,
Colt1911 [192]
Nut A does not fit on Bolt A.

Bolt A is the exact same as Bolt B.

So it follows that Nut A will not fit Bolt B.

8(2x + 3) = PxQ
anyanavicka [17]

Respuesta:

P = 16; Q = 24

P = 0; Q = 0

Explicación paso a paso:

Dada la relación:

8 (2x + 3) = Px + Q

Abra el soporte

16x + 24 = Px + Q

Los valores de P y Q para los que la ecuación tiene infinidad de solución:

Px = 16x

Q = 24

Por tanto, en P = 16; Q = 24, la ecuación tiene infinidad de soluciones.

Valores de P y Q para los que la ecuación no tiene solución:

Px = 0; P = 0

Q = 0

Por tanto, los valores de P y Q para los que la ecuación no tiene solución es 0
