LOTS OF POINTSFind The Perimeter Of The Figure Below, Composed Of A Parallelogram And One Semicircle.

Answers

Answer 1

Answer:

38.3

Step-by-step explanation:

The perimeter of the figure can be broken down into the perimeter of 3 sides of the parallelogram, and the perimeter of the semicircle (without its diameter).

The three sides of the parallelogram would be 14+14+4=32.

The perimeter of the semicircle would be 1/2*diameter*pi, which is about 1/2*4*3.14=6.28.

Therefore, the perimeter is 32+6.28=38.3 (to the nearest tenths).

Answers

15/2.49 = 6.02 round down to a whole number is 6

Answer: 6.02

Step-by-step explanation:

If we know 1 gallon = 2.49

We would have to do 15.00 divided by 2.49 in order to figure out how many gallons we need. When we do that we would get 6.024 but you can round by the nearest tenth because you need to have a whole number and you would get 6 ·ω·

Heyyy! What is 0.45 (5 repeating) as a fraction?

Answers

Answer:

41/90

Step-by-step explanation:

- The answer given above does not actually have the repeating 5, this fraction does:

x = 0.455555

100x = 45.55555

10x = 4.5555555

90x = 41 (rounded)

therefore, the fraction is 41/90

What is 5x-7(x+1)=9
Thanks for the help

Answers

Answer:

x = -8

Step-by-step explanation:

Step 1: Write equation

5x - 7(x + 1) = 9

Step 2: Solve for x

Distribute -7: 5x - 7x - 7 = 9Combine like terms: -2x - 7 = 9Add 7 to both sides: -2x = 16Divide both sides by -2: x = -8

Step 3: Check

Plug in x to verify it's a solution.

5(-8) - 7(-8 + 1) = 9

-40 - 7(-7) = 9

-40 + 49 = 9

9 = 9

Answers

Answer:

the measure of angle 4 is 52 degrees.

Step-by-step explanation:

The measure of angles 3 and 4 added together is 90 degrees. Angle 3 is 38 degrees. 90-38=54.

Answer:

∠ 4 = 52°

Step-by-step explanation:

The 3 angles lie on a straight line and sum to 180°, that is

90 + ∠ 3 + ∠ 4 = 180, substitute ∠ 3

90° + 38° + ∠ 4 = 180°

128° + ∠ 4 = 180° ( subtract 128° from both sides )

∠ 4 = 52°

There are 365 days in a year and 24 hours in a day. An airport camera records for 18 hours and then automatically resets itself to start recording again how many times does the video camera reset itself in a year.
pls help

Answers

The answer is 486.6

There are 8,760 hours in a year, so 18 divided by 8,760 would = 486.6

Answer:

Step-by-step explanation:

You could do it this way.

How many hours are there in a year?

365 * 24 = 8760 hours.

This camera does not recognize days. It works on hours. Every 18 hours it resets. So

8760/18 = 486  and 2/3 times.

Obviously it cannot have 2/3 of a day. Normally you would round up, but this time you round down.

The answer is 486 times.

2/3 * 24 = 16

The camera would reset 2 hours into the next day.

If 3x+4y=4 and 2x+y=1, then the value of 2x+3y is equal to

Answers

Answer:

3.

Step-by-step explanation:

3x + 4y = 4..........1

2x + y = 1.............2           Multiply this by 4:

8x + 4y = 4     Subtract this from equation 1:

-5x = 0

x = 0.

So substituting in equation 2:

2(0) + y = 1

y = 1.

Therefore 2x + 3y = 2(0) + 3(1) = 3.

Step-by-step explanation:

A screwdriver is dropped from the top of an elevator shaft. Exactly 6.0 seconds later, the sound of the screwdriver hitting bottom is heard. How deep is the shaft? Hint: The distance that a dropped object falls in t seconds is represented by the formula s = 16t2. The speed of sound is 1100 ft/sec. The shaft is approximately (Round to the nearest tenth.) | feet deep.

Answers

Answer:

Step-by-step explanation:

Using the equation of motion

S = ut+1/2gt²

S is the height of fall

g is the acceleration due to gravity = 9.81m/s²

u is the initial velocity = 0m/s

t is the time = 6s

Substitute in the formula;

S = 0+1/2(9.81)×6²

S = 4.905×36

S = 176.58m

The shaft is 176.58m deep

Given the expression for distance

S = 16t²

Velocity V = dS/dt

V = 32t

Given v = 1100

1100 = 32t

t = 1100/32

t = 34.375secs

Substitute t = 34.375 into S = 16t²

S = 16(34.375)²

S = 18,906.25ft
