Answer 1

Answer:

∠AOC = 98°

∠BOC = 82°

∠DOE = 39°

Step-by-step explanation:

∠DOE = 180 - (43 + 98)

= 39°

∠BOC = 180 - ∠DOB

= 180 - 98

= 82°

∠AOC = ∠DOB (they are vertical angles which are equal)

Answers

3x - 1 can be written in a verbal form as "1 less than the product of 3 and a number x

Functions can be translated using words in mathematics

Given the function 3x - 1

Let x be the unknown number

3x is translated as the product of 3 and a number.

Since 1 is subtracted from the function this means that the function 3x is lesser by a value of 1.

In this case, 3x - 1 can be written in a verbal form as " less than the product of 3 and a number x

Answer:

Step-by-step explanation:

The three pairs of corresponding angles have the same measures, so the triangles are similar by AA similarity. However, at least one pair of corresponding sides must be shown congruent before the triangles can be declared congruent.

There is nothing in the diagram to require the triangles be congruent.

With three corresponding equal angles triangles are not congruent. Therefore, the given statement is false.

What is the congruence theorem?

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

The three pairs of corresponding angles have the same measures, so the triangles are similar by AA similarity. However, at least one pair of corresponding sides must be shown congruent before the triangles can be declared congruent.

With three corresponding equal angles triangles are not congruent. Therefore, the given statement is false.

PLEASE HELP MEEEE!!!!!!!!!

Answers

Answer:

a) 1,144 rad/min

b) 182.1 rev/min

Step-by-step explanation:

d= 24 inches

radius = 24/2 or 12 inches

speed = 13mi/h

need to convert speed to inches/min

v = Θ * r

1 mile = 63360 inches, and 1 hour = 60 min

13 mi * (63360 in / mi)

= 823680 in / (1 hr * 60 min / hr)

=13728 in/min

Now go back to the equation

13728 in / min = ω * 12 in

13728 /12 = Θ

1,144 rad/min

b) 1 revolution = 2π

w= Θ/2π

w= 1,144rad/ min/2pi rad

w= 182.1 rev/min

The governor of state A earns $51,615 more than the governor of state B. If the total of their salaries is $291,335, find the salaries of each.

Answers

Answer:

A = $171,475, B = $119,860

Step-by-step explanation:

A represents the salary of the governor of state A.

B represents the salary of the governor of state B.

A is $51615 larger than B, so you get the equation:

A = B + 51615

The total of the two salaries is $291335, so you can the second equation:

A + B = 291335

Using the first equation, substitute the quantity (B + 51615) for A in the second equation.

(B + 51615) + B = 291335

2B + 51615 = 291335

2B = 239720

B = 119860

Plug this value of B back into either of the equations.

A = B + 51615 = 119860 + 51615 = 171475

A man covers a distance of 150m in 1.5mins. Find the average speed in km per hour

Answers

Answer:

6 Km / hour

Step-by-step explanation:

Convert distance to Km ( 1 Km = 1000 m )

150 m = 150 ÷ 1000 = 0.15 Km

Convert 1.5 mins to hours ( 1 hour = 60 minutes )

1.5 = 1.5 ÷ 60 = 0.025 hours

average speed = [tex]\frac{distance}{time}[/tex] = [tex]\frac{0.15}{0.025}[/tex] = 6 Km / hour

The average speed in km per hour is 6 kilometers per hour

How to determine the average speed?

The given parameters are:

Distance = 150 mTime = 1.5 mins

Convert meters to kilometers

Distance = 150/1000 km

Distance = 0.15 km

Convert minutes to hours

Time = 1.5/60 hour

Time = 0.025 hour

The average speed is then calculated as:

Speed = Distance/Time

This gives

Speed = 0.15 km/0.025 hour

Evaluate

Speed = 6 kilometers per hour

Hence, the average speed in km per hour is 6 kilometers per hour

Find the surface area of the following cylinder.

Round your answer to the nearest square centimeter.

Answers

The surface area, to the nearest square centimeter, of the given cylinder is: 182 cm²

Recall:

Surface area of a cylinder = 2πrh + 2πr²

From the diagram given, we have:

radius (r) = half of diameter = 10/2 = 5 cmheight (h) = 0.8 cm

Substitute each value into the surface area formula for a cylinder.

Thus:

Surface area = 2(π)(5)(0.8) + 2(π)(5²)

Surface area = 182.212

Therefore, the surface area, to the nearest square centimeter, of the given cylinder is: 182 cm²
