We're given the hypotenuse and the opposite side so that means that we're gonna be using the inverse of sine to find the angle.

${sin}^{ - 1} = \frac{opp}{hyp} = \frac{6}{12}$

$= 30 \: degrees$

How many cardboard did Shauna use to marry the box

DiKsa [7]

Answer:

D. 360 in.²

Step-by-step explanation:

Since all the answers are labeled as in.², we know that we have to find the area of the rectangular prism. The formula for area of a rectangular prism is: lwh (length x width x height).

l = 12

w = 6

h = 5

12 x 6 x 5 = 360

Drag numbers to fill in the table to organize the information in this problem. Carter works for a fence company. He can paint a

OLEGan [10]

Answer:

394.67 minutes (or about 6.58 hours)

Step-by-step explanation:

For 145.8 feet long fence:

At a rate of 2.25 feet per minute, its gonna take him

$\frac{145.8}{2.25}=64.8$ minutes to pain

Also

At a rate of 0.75 feet per minute, its gonna take him

$\frac{145.8}{0.75}=194.4$ minutes to stain

For 76.2 feet long fence:

At a rate of 2.25 feet per minute, its going to take him

$\frac{76.2}{2.25}=33.87$ minutes to pain

At a rate of 0.75 feet per minute, its gonna take him

$\frac{76.2}{0.75}=101.6$ minutes to stain

In total, it's gonna take him:

64.8 + 194.4 + 33.87 + 101.6 = 394.67 minutes

In hours, that is 394.67/60 = 6.58 hours

What is the measure of x?

UkoKoshka [18]

Answer:

x=4

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(x+5) *x = 6^2

x^2 +5x = 36

Subtract 36 from each side

x^2 +5x - 36 = 0

Factor

( x-4) (x+9) = 0

Using the zero product property

x-4 = 0 x+9 =0

x = 4 x=-9

Cannot be negative since that is negative length

x=4
