The answer is B. 34.7

Take the cosine (adjacent over hypotenuse) of 38°
Multiply this number by 44 (the hypotenuse)

Your answer is 34.67, which rounds to 34.7

find the missing angle measure in each triangle. Then classify the triangle as acute, right, or obtuse. PLEASE ANSWER QUICK ILL

larisa86 [58]

X=72 cause 180-(51+57) so 180-108 and the triangle is acute cause all of the angle measures are below 90 degrees.

So your answer is
x=72
Acute Triangle

bazaltina [42]

(40 * 25) + 0.10x = (40 * 20) + 0.20x
1000 + 0.10x = 800 + 0.20x
1000 - 800 = 0.20x - 0.10x
200 = 0.10x
200/0.10 = x
2000 = x <=== weekly sales must be $ 2000

the volume of a cube is increasing at a constant rate of 824 cubic centimeters per minute. At the instant when the volume of the

Maurinko [17]

Answer:

DA/dt = 75.27 cm²

Step-by-step explanation:

Cube Volume = V(c) = 683 cm³

DV(c) /dt = 824 cm³

V(c,x) = x³

Then

DV(c,x)/ dt = 3x² Dx/dt

( DV(c,x)/ dt )/ 3x² = Dx/dt (1)

Now as V(c,x) = x³ when V(c,x) = 683 cm³ x = ∛683

x = 8.806 ( from excel)

And by subtitution of this value in equation (1)

Dx/dt = ( DV(c,x)/ dt )/ 3x² ⇒ Dx/dt = 824 / 3*x²

Dx/dt = 824 /3*77.55

Dx/dt = 824/232,64

Dx/dt = 3,542

Then we got Dx/dt where x is cube edge. The area of the face is x² then

the rate of change of the suface area is

DA/dt = ( Dx/dt )²*6 ( 6 faces of a cube)

DA/dt = (3.542)²*6

DA/dt = 75.27 cm²

An animal shelter spends $3.00 per day to care for each cat and $6.50 per day to care for each dog. Amelia noticed that the shel

Ede4ka [16]

Answer:

There were 15 cats at the shelter on Friday.

Step-by-step explanation:

Cost of caring each cat = $3.00

Cost for caring each dog = $6.50

Total money spent by shelter = $84.00

Total Cats and Dogs in the shelter = 21

Let the number of cats in the shelter = k

So, the number of dogs in shelter = 21 -k

Also according to the question:

Total expenditure on cats + total expenditure on dogs = $84.00

or, k ($3.00) + (21-k)($6.50) = $84.00

or, 3k + 136.5 - 6.5 k = 84

or, -3.5 k = 84 - 136.5 = -52.5

⇒3.5 k = 52.5 or k = 52.5/3.5 = 15

⇒ k = 15

Hence, the number of cats in the shelter was 15 on Friday.
