Answer:

C - 6 < = 5.3

Step-by-step explanation:

Writing the above as an equality, we would have ;

Since C is less than 6, then;

C - 6

Therefore, C minus 6 is less than or equal to 5.3 is

C - 6 < = 5.3

An inequality is when an unequal relationship exist between two expressions, which uses signs such as not equal to , less than < , greater than > etc.

Answer:

480

Step-by-step explanation:

12 x 60 = 720

1200 - 720 = 480

Answer: 1,920

Step-by-step explanation:

12ft per second, so to find out his elevation after one minute you would have to convert from seconds to minutes. (60 sec = 1 min). So you would do 12*60 to get 720. And since he already started at 1,200 feet, you add 720. So 1,200+720 = 1,920 ft.

Step-by-step explanation:

Answer:

The slowest train goes at 86 mph and the fastest train goes at 96 mph.

Step-by-step explanation:

Distance and Speed

Assume x is the speed of the slowest train, therefore the speed of the fastest train is x+10.

The distance is calculated as:

d = vt

Where v is the speed and t is the time.

The distance traveled by each train in 5 hours is:

Slowest: 5x

Fastest: 5(x+10)

The sum of both distances is 910 miles:

5x + 5(x + 10) = 910

Operating:

5x + 5x + 50 = 910

10x = 910 - 50 = 860

x = 860/10

x = 86

The slowest train goes at 86 mph and the fastest train goes at 96 mph.

Answer: 3234 cubic units

Step-by-step explanation:

Volume of cylinder: πr²h

The diameter of the cylinder is 14 units so the radius is 7 units.

Now we'll substitute.

π = 22/7

h = 21

πr²h

π × 7² × 21

22/7 × 49 × 21 = 3,234

The volume is 3,234 cubic units.

Answer: Jerry walked 2 7/20 miles to get to the park

Step-by-step explanation:

1/2 of 3 1/2

1/2 of 7/2 = 7/4

7/4 + 3/5

Find the LCM of the denominator

LCM of 4 and 5 = 20

35/20 + 12/20 = 47/20 = 2 7/20

Answer:

126

Step-by-step explanation:

  70

If Ed and Whitney are 70 feet apart, then Candice and Ed are 42 feet apart.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that the Candice is deep-sea diving with two friends

Whitney is exploring a coral reef 56 feet in front of Candice

The distance between Whitney and Candice is 56 feet.

Ed is floating on the surface directly above Candice.

Ed and Whitney are 70 feet apart, we need to find the distance between Ed and candice.

By using Pythagoras theorem we can find this.

70²=56²+x²

4900=3136+x²

Subtract 3136 from both sides

4900-3136=x²

x²=1764

Take square root on both sides

x=42

Hence, If Ed and Whitney are 70 feet apart, then Candice and Ed are 42 feet apart.

Work Shown:

Problem 1

6 cups water: 4 cups flour

(6/2) cups water: (4/2) cups flour

3 cups water: 2 cups flour

3:2 is the ratio of water to flour

In the second step, I divided both parts by the GCF 2 to reduce the ratio.

-------------------------

Problem 2

(3 cups water)/(2 cups flour) = (x cups water)/(6 cups flour)

3/2 = x/6

3*6 = 2*x ... cross multiply

18 = 2x

2x = 18

x = 18/2

x = 9

You'll need 9 cups of water

-------------------------

Problem 3

(3 cups water)/(2 cups flour) = (2 cups water)/(y cups flour)

3/2 = 2/y

3y = 2*2

3y = 4

y = 4/3

y = (3+1)/3

y = 3/3 + 1/3

y = 1 + 1/3

y = 1 & 1/3

You'll need 1 & 1/3 cups of flour

This value is a mixed number with the first "1" being the whole part, and the 1/3 being the fractional part.

This is saying you'll need 1 full cup of flour, plus an additional one-third cup of flour to go on top of that.

Step-by-step explanation:

Answer:

a = 249 and b = 1.16

Step-by-step explanation:

Consider the provided information.

The exponential function for growth is:  [tex]y=a(1+ r)^x[/tex]

Here, a is the initial value and r is the rate of change.

It is given that the number of birds is 249.

It means a = 249

The rate is given 16%

r=0.16

Put the value of a and r in the above formula.

[tex]y=249(1+0.16)^x[/tex]

[tex]y=249(1.16)^x[/tex]

Now we will compare it with the exponential function form [tex]y=ab^x[/tex]

Therefore, a = 249 and b = 1.16

Step-by-step explanation:

y = -3x² + mx + 10

dy/dx = -6x + m.

When dy/dx = 0, -6x + m = 0. => x = m/6.

We have y = -3(m/6)² + m(m/6) + 10 = 37.

=> -m²/12 + m²/6 = 27

=> -m² + 2m² = 324

=> m² = 324

=> m = 18 or m = -18.

Answer:

Step-by-step explanation:

x²-2=2⅔ +2-⅔

x^2 = 2^1 + 2⅔ +2-⅔

x^2 =   4.21736

x = 2.0536.

Plug this into 2x^3 - 6x:

= 2(2.0536)^3 - 6(2.0536)

= 5

So 2x^3 - 6x = 5.

Answer:

g(f(x)) = -x^2 + 4

Step-by-step explanation:

What we simply have to do here is to put f(x) into g(x)

What this mean is that every x in g(x) will be represented by f(x)

Thus, we have it that

-x^2 - 1 + 5

= -x^2 + 4

Answer:

See below.

Step-by-step explanation:

Create a system of equations to represent this scenario.

1) A graph of these equations is attached below. Lin is in red; Diego is in blue.

2) The time (seconds) is on the x-axis, while the milkshake (oz) is on the y-axis. The graph shows the rate of change that the volume of the milkshake is decreasing for both Lin and Diego. The intersection point tells us at what time t (s) Lin and Diego have the same amount of milkshake left.

There is only one solution to this system of equations: (24, 4). This tells us that at t = 24 s, Lin and Diego both have 4 oz of milkshake left.

The zeros, aka where the graph touches the x-axis, tell us at what time Lin and Diego finish their milkshakes.

Lin finishes her milkshake later than Diego, at t = 36 s (36, 0), while Diego finishes his milkshake at t = 30 s (30, 0).
