Find the measure of the arc or central angle indicated. Assume that lines which appear to be
diameters are actual diameters.

Answer:

r

Step-by-step explanation:

sin is o/h so across from 12 would be the angle r

Answer is Option-D => ∠R

Sinθ Formula:

The sine of an angle of a right-angled triangle is the ratio of its perpendicular (that is opposite to the angle) to the hypotenuse. The sin formula is given as: sinθ = Perpendicular / Hypotenuse

Here, (Given)

Perpendicular = 12

Hypotenuse = 37

So, For sinR, we get 12/37 value as the opposite side of an angle ∠R is 12.

Answer is ∠R.

Answer:

72 cm³

Step-by-step explanation:

i just took the test :)

The volume of the given right square pyramid is 72 cm³. The correct answer would be an option (A).

The formula for the volume of a right square pyramid is:

V = (1/3) B × h

where B is the area of the base and h is the height of the pyramid.

Since the perimeter of the base is 24 cm, and there are four equal sides, each side must be 24/4 = 6 cm.

The area of the square base is:

B = s² = 6² = 36 cm²

The volume of a right square pyramid is:

V = (1/3) B × h

Substituting in the given values, we get:

V = (1/3) × 36 × 6

V = 72 cm³

Therefore, the volume of the pyramid is 72 cm³.

Answer:

14 minutes

Step-by-step explanation:

The barrel held 21 quarts of oil, which is equal to 84 cups. Trina drains the barrel at 6 cups per minute, so to find out how much time it takes her to drain it, divide 84 by 6:

84 / 6 = 14

So, it took Trina 14 minutes to drain the whole barrel.

Answer:

$15.20

Step-by-step explanation:

When you are asked to find the mean, you would add up the costs of the shirts and then divide them by however many shirts she got.

56.80 + 19.20 = 76

76 ÷ 5 = 15.20

Thus the mean cost is $15.20

Answer:

A: 1800h-25,000

B: Yes, he would have time.

Step-by-step explanation:

A:

Lets turn 30 gallons/minute into hours so we can make it easier.

18000h-25000

Then plug in h which is hours. To get your answer

B:

From May 7 at 8:00 a.m. to May 8 at 12 p.m. would be 28 hours.

So we plug in 28 for h and get our answer of 25400 gallons/hour

Answer:

Step-by-step explanation:

7+3 = 10 $4+$6=$10

so it costs 10 dollars to make ten cards, how many times does 10 go into 25? 2

so $20 so far, I'm not that good at explaining.

Now with the remaining 5 cards that we have to make, we add three and have 24$ for 23 cards. Now with the remaining two cards we add $1.50.

because 2 x 1.50 = 3

so $25.50 for 25 cards I think...

I really hope I'm right and I hope this helps!

Answer:

See Explanation

Step-by-step explanation:

For an object at temperature T and supposing that the ambient temperature is Ta then we can write the differential equation that typifies the Newton law of cooling as follows;

dT/dt=-k(T-Tₐ)

So

dT/dt = 2 degrees Celsius per minute

T = 70 degrees Celsius

Ta = 25 degrees Celsius

2 = -k(70 - 25)

-k = 2/(70 - 25)

k = - 0.044

Hence we can write;

dT/dt=-(- 0.044)(95-25)

dT/dt= 3 degrees Celsius per minute

Answer:

[tex]BA = 6.0[/tex]

[tex]BC = 13.4[/tex]

Step-by-step explanation:

Given

The attached triangle

Solving (a) BA

Considering the tangent of angle C, we have:

[tex]tan\ C = \frac{BA}{AC}\\[/tex]

This gives:

[tex]tan\ 25 = \frac{BA}{12}[/tex]

Make BA the subject

[tex]BA = 12 * tan\ 25[/tex]

[tex]BA = 12 * 0.4663[/tex]

[tex]BA = 6.0[/tex] --- approximated

Solving (a) BC

Using Pythagoras theorem

[tex]BC^2 = BA^2 + AC^2[/tex]

[tex]BC^2 = 6.0^2 + 12^2[/tex]

[tex]BC^2 = 180[/tex]

Square root of both sides

[tex]BC = \sqrt{180[/tex]

[tex]BC = 13.4[/tex]

Answer:

domain:{10,28,42,52}

range:{-10,6,10}

Step-by-step explanation:

Hello There!

If you didn´t know the domain is the set of x values

the x values in the given relation are

10,28,42,10 and 52

so the domain is {10,28,42,52}

The range is the set of y values

the y values in the given relations are

6,-10,6,10,10

so the range is {-10,6,10}
