Solve for x in the equation 3x2 - 18x+5=47.

Answer:

11.8 m:

Step-by-step explanation:

Volume = pi×r²×h
95 = pi×1.6²×h
h = 95/(pi×1.6²)
h = 11.8122809326
h = 11.8 m (nearest tenth)

Answer:

11.8 m:

Step-by-step explanation:

Volume = pi×r²×h

95 = pi×1.6²×h

h = 95/(pi×1.6²)

h = 11.8122809326

To solve this we first of all need to find the distances travelled by both Vaimiti and Jabril and then we will find their difference...

Let's start solving ~

Distance covered by Vaimiti ⤵️

[tex] \tt \leadsto \: Distance = Speed × Time[/tex]

Vaimiti's speed = 1.1 m/s

Time taken by her = 25 minutes = 25×60 = 1500 seconds

[tex] \sf \leadsto \: Distance = 1.1 \times 1500[/tex]

[tex] \boxed{ \rm\multimap \: Distance = 1650 \: m}[/tex]

Distance covered by Jabril ⤵️

[tex] \tt \leadsto \: Distance = Speed × Time[/tex]

Jabril's speed = 1.3 m/s

Time taken by her = 30 minutes = 30×60 = 1800 seconds

[tex] \sf \leadsto \: Distance = 1.3\times 1800[/tex]

[tex] \boxed{ \rm\multimap \: Distance = 2340 \: m}[/tex]

[tex]\rule{300pt}{3pt}[/tex]

Difference between distances travelled by them↯

Distance travelled by Vaimiti = 1650 m

Distance travelled by Jabril = 2340 m

[tex] \bf\nRightarrow \: Difference = 2340 - 1650[/tex]

[tex] \bf \nRightarrow \: Difference = 690 \: m[/tex]

➪ Therefore, The difference between distance travelled by them is 690 meter...~

Answer:

5 hours and 30 minutes

Step-by-step explanation:

Convert all fractions to decimals for easier division

9 and 5/8 = 9.625

1 and 3/4 = 1.75

Then divide 9.625 by 1.75 to get the hours amount

9.625 / 1.75 = 5.5

0.5 of an hour is 30 minutes, so the final answer is 5 hours and 30 minutes

Answer:

5.5 hours

Step-by-step explanation:

9.625/1.75=5.5hr

Answer:

n/4-9 +3

Step-by-step explanation:

to answer this question we have to analyze the information given.

The quotient of a number means the result of the division of 2 numbers.

In this case the numbers are: a number (n) and 4 . n/4

Nine less than that quotient means we have to subtract 9 to the quotient.

n/4-9

Increase by three: we simply have to add 3

n/4-9 +3

Answer:

     x ≈ 67.1

Step-by-step explanation:

The side adjacent to x° is given, along with the hypotenuse. That suggests the relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(x°) = 28/72 = 7/18

The angle is found from the cosine using the inverse cosine function:

  x° = arccos(7/18)

  x° ≈ 67.1°

Step-by-step explanation:

The height of the flagpole to the nearest hundredth is 11.41 m

In order to get the height of the flagpole, we will use the similarity theorem of shapes.

From the given diagram, we will have the expression

1.65/1.15 = x/7.95

Cross multiply

1.15x = 1.65 * 7.95

1.15x = 13.1175

x = 13.1175/1.15

x = 11.406

Hence the height of the flagpole to the nearest hundredth is 11.41 m

Answer:

d) 35ft

e) 6 seconds

f) 250°

Step-by-step explanation:

If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.

   36 secs = 360°

⇒ 1 sec = 360/36 = 10°

d)  After 9 seconds, it has turned:

9 x 10 = 90°

Therefore, it will be 15 + 20 = 35ft from the wall

e) 60° = 6 seconds

f) 25 seconds = 25 x 10 = 250°

Answer:

(3, -6)

Step-by-step explanation:

Both equations are equal to y, so you can make them equal to each other:

-2x = 5x-21

Get the same terms on the same side by subtracting 5x from both sides"

-7x = -21

Get x alone by dividing both sides by -7:

x = 3

The simplest way to find y is by filling in 3 for x in the first equation:

y = -2(3)

Multiply:

y = -6

Check your answer by filling in 3 for x in the second equation:

y = 5(3) - 21

Multiply:

y = 15 - 21

Subtract:

y = -6

To check both answers together, fill in 3 for x and -6 for y in both equations (although we already checked both answers above):

-6 = -2(3)

-6 = -6

-6 = 5(3) - 21

-6 = 15 - 21

-6 = -6
