Answer:

36.5 = AC

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj side/ hypotenuse

cos A = AC / AB

cos 51 = AC /58

58 cos 51 = AC

36.50058 = AC

Rounding to the nearest tenth

36.5 = AC

A box contains 95 pink rubber bands and 90 brown rubber bands. You select a rubber band at random from the box. Find each probab

vivado [14]

Answer:A. The theoretical probability for pink is 95/185 or about 51.35%

B. The theoretical probability for brown is 90/185 or about 47.82%.

C. To find the experimental probability, we will make another fraction. The number of outcomes will be the numerator and the total will be the denominator.

Pink 36/69 = 52.17%

Brown 33/69 = 47.82%

Connie's dog fido weighs 35 pounds. Her vet placed fido on a diet. What inequality can you write to find the average number of p

lawyer [7]

Fido's dog must lose 1.17 pounds each month to reach healthier weight.

Step-by-step explanation:

Given,

Weight of fido's dog = 35 pounds

Time period = 6 months

Goal weight to reach = 28 or less pounds

Let,

m be the weight to be lose each month.

Weight of dog - Time period * Weight to lose each month ≤ Goal weight

$35-6m\leq 28\\-6m\leq 28-35\\-6m\leq -7$

Dividing both sides by -6

$\frac{-6m}{-6}\leq \frac{-7}{-6}\\\\m\leq 1.17$

Fido's dog must lose 1.17 pounds each month to reach healthier weight.

alexdok [17]

Let h = weight of the hardcover book.
Let p = weight of the paperback book.

"The hardcover version of a book weighs twice as much as its paperback version."

h = 2p

"The hardcover book and the paperback together weigh 5.3 pounds."

h + p = 5.3

The equations are:

h = 2p
h + p = 5.3

Angle θ is in standard position and (−6,−3) is a point on the terminal side of θ. What is the exact value of csc θ in simplest f

bearhunter [10]

Answer:

$\displaystyle \csc\theta=-\frac{\sqrt{5}}{2}$

Step-by-step explanation:

Since $\displaystyle \csc\theta=\frac{1}{\sin\theta}=\frac{1}{\frac{\text{Opposite}}{\text{Hypotenuse}}}=\frac{\text{Hypotenuse}}{\text{Opposite}}$ , we need to find the hypotenuse given our corresponding opposite and adjacent lengths of -6 and -3 accounting for Quadrant III:

$(-6)^2+(-3)^2=c^2\\\\36+9=c^2\\\\45=c^2\\\\\sqrt{45}=c\\\\c=3\sqrt{5}$

Thus, $\displaystyle \csc\theta=\frac{\text{Hypotenuse}}{\text{Opposite}}=\frac{3\sqrt{5}}{-6}=-\frac{\sqrt{5}}{2}$
