A number c minus 6 is less than or equal to 5.3. Write this word sentence as an inequality.
An inequality is
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.

Determined to finish her milkshake before Diego, Lin now drinks her 12 ounce milkshake at a rate of 1/3 an ounce per second.
Diego starts with his usual 20 ounce milkshake and drinks at the same rate as before, 2/3 an ounce per second.
1) Graph this situation on
2) What does the graph tell you about the situation and how many solutions there are?
Answer:
See below.
Step-by-step explanation:
Create a system of equations to represent this scenario.
Lin: 12 - 1/3x = yDiego: 20 - 2/3x = y1) 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).
From stations A and B, the distance between which is 910 mi,
two trains left simultaneously moving towards each other. The
speed of one train was 10 mph greater than the speed of the
other one. In 5 hours the trains met. Find the speed of each train.
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.
5 pencils cost £4.25.
How much do 9 pencils cost?
Answer:
£ 7.65
Step-by-step explanation:
Cost of 5 pencils = £ 4.25
Cost of 1 pencil = £ 4.25 / 5 = £ 0.85
Now
Cost of 9 pencils = £ 0.85 * 9 = £ 7.65
Hope it will help :)❤
Step-by-step explanation:
Hey there!
Given;
The cost of 5 pencils is £ 4.25.
Cost of 9 pencils= ?
Now;
~ Finding cost of one pencil.
Cost of 1 pencil= £4.25/5
= £0.85
~ Finding cost of 9 pencils.
Cost of 9 pencils= £9*0.85
= £7.65
Therefore, the Cost of 9 pencils is £7.65.
Hope it helps....

3) A skier traveled downhill at a rate of 12 feet per second. If he started at an elevation of 1,200 feet, what is his elevation after one minute?
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.

A population of 249 birds increases at a rate of 16% annually. jewel writes and exponential function of the form f(x)=abc to represent the number of birds after x years. Which values should she use for a and b
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
If x²-2=2⅔ +2-⅔
then prove that 2x³-6x =5 solve and send photo please
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.

could someone help me with this please, thank u
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

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.

Round your answer to the nearest million dollars.
If the maximum value of y=-3x² + mx + 10 is 37, find the values of m.
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.

A recipe calls for 6 cups of water and 4 cups of flour. a. What is the ratio of water to flour?
b. If the recipe is increased to use 6 cups of flour, how much water should be used?
c. If the recipe is decreased to use 2 cups of water, how much flour should be used?
Answers:
a) The ratio of water to flour is 3:2b) 9 cups of waterc) 1 & 1/3 cups of flour====================================================
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.

126
If Ed and Whitney are 70 feet apart, then Candice and Ed are 42 feet apart.
What is Trigonometry?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.
