What is the slope of the line shown in the graph below?
Answer:
2/3
Step-by-step explanation:
Between the two points, the line goes up 4 points and to the right 6 points. The slope is rise over run, so in this case the rise is 4 and the run is 6
This makes our slope:
4/6 which simplifies to 2/3

The level of water in a tank is 16 feet. The level decreases steadily, and the tank is emptied in 8 hours. What was the change in water level in the tank during the first hour?
Answer:
During the first hour, the water change was 2 feet (or 14 feet)
Step-by-step explanation:
We know that the level of water in a water tank was 16 feet, and that by 8 hours, it was empty. To find the change in the water level per hour, we need to divide 16 by 8.
16 ÷ 8 = 2
Therefore, during the first hour, the water change was 2 feet (or 14 feet)

Answer: Lunch:$16 Coffee: $4 Julie had $12 left.
Step-by-step explanation:
Answer:
1. Lunch ($16)
2. Coffee ($4)
3. how much money did she have left?
she had ($12) left
Step-by-step explanation:
1. To get the amount of money she used on lunch you have to look at the word problem it says "she spent 1/2 of her money on lunch" her total is $32 dollars and 1/2 is .5 as a decimal and 50% as a percentage so 50% of 32 is (16) so she spent $16 dollars on lunch alone.
2. To find how much money she used on Coffee you need to read the context of the problem its asking for "how much did she use of the money that is left from her lunch" so she has $16 dollars she used from lunch so now it wants you to find 1/4 of $16 dollars or 25% of 16 and 25% of 16 is (4)
so she spent 4 dollars of what was left so the answer is 4.
3. To find how much is left add up 16 and 4 and you get 20 then subtract it by the original number which is 32 so it should look like this 32 - 20 = 12
so the money she has left is $12 dollars.

__________________MIGHTY MT. EVEREST
The Earth’s surface is composed of gigantic plates that are constantly moving. Currently, India lies on a plate that is slowly drifting northward. India’s plate is grinding into the rest of Asia. As it does so, it pushes up the Himalayan Mountains, which contain the world’s highest peak, Mt. Everest. In 1999, mountain climbers measured Mt. Everest with satellite gear and found it to be 8850 meters high. Geologists estimate that Mt. Everest may be growing by as much as 5 cm per year.
Your Task: Assuming a constant growth of cm per year, determine how tall Mt. Everest was in the year 0. (The year 0 is the year that came 2000 years before the year 2000.) Write an equation for the height of Mt. Everest over time, with x representing the year and y representing the height of the mountain.
What are the units for m and b in your equation? How many decimal places should be in your answer? Explain why.
The general equation representing the height of Mt. Everest over time can be written as → y = 0.05x + 8850. The unit of 'b' is meters and 'm' is a dimensionless quantity.
What is a time - varying quantity?A quantity whose magnitude is a function of time is called a time - varying quantity. For example → x = 2t.
Given is the measured height of Mt. Everest with the help of satellite gear. Geologists estimate that Mt. Everest is growing by as much as 5 cm per year.
Height of Mount Everest in the year 1999 → 8850 meters.
Rate at which Mt. Everest grows per year → 5 cm/yr = 1/20 m/yr.
The general equation representing the height of Mt. Everest over time can be written as →
y = 0.05x + 8850
where -
'x' represents the year.
'y' represents the height of the mountain.
The general equation of a straight line is given by -
y = mx + b [ m → slope, b → y-intercept ]
'y' represents height and is measured in meters. The slope 'm' of line is a dimensionless quantity as it the ratio of two lengths (y/x) and 'b' is measured in meters.
Now for x = - 2000
y = - 100 + 8850
y = 8750 m
Therefore, the general equation representing the height of Mt. Everest over time can be written as → y = 0.05x + 8850. The unit of 'b' is meters and 'm' is a dimensionless quantity.

The speed of sound in air is 343 meters per second. You see lightning and hear thunder 12 seconds later.
The distance from the lightning strike is 4,116 meter.
What is relation between speed, distance and time?
The relation between speed, distance and time is defined as,
Distance = Speed x Time
Given that;
The speed of sound in air = 343 meters per second
Time to see lightning and hear thunder = 12 second.
Since, Distance = Speed x Time
Substitute values in above equation,
Distance = 343 x 12
= 4,116 meter.
Hence, The distance from the lightning strike is 4,116 meter.

Solve the following simultaneous equations 2x+5y=0 and 3x-4y=23
Answer:
x = 5, y = -2
Step-by-step explanation:
2x + 5y = 0 --- Equation 1
Equation 1×3: 6x + 15y = 0 --- Equation 2
3x - 4y = 23 --- Equation 3
Equation 3×2: 6x - 8y = 46 --- Equation 3
We will be eliminating 6x from Equation 2.
Equation 3-2: 6x - 8y - 6x - 15y = 46-0
-23y = 46
y = 46 ÷ -23
y = -2
Substitute y = -2 into Equation 1:
2x + 5y = 0
2x + 5(-2) = 0
2x + (-10) = 0
2x - 10 = 0
2x = 10
x = 10 ÷ 2
x = 5

2x-y=7
x*2+y*2=49
(x, y) = (0, -7) and ((28/5 , 21/5)) , as found by solving the system of linear equations.
What is a system of linear equations?
A system of linear equations is a set of two or more linear equations. Linear equations refer to the equations that involve two or more variables in the form of "ax + b".
Given: 2x - y = 7x² + y² = 49
to find: Values of x and y.
Finding:
Solving the system of two linear equations, by deriving the value of one variable from an equation and substituting it in the other equation and solving for the two variables.
eqn1 2x - y = 7
y = 2x - 7
eqn2 x² + y² = 49O
substituting the value of y from eqn1,
we get: x² + (2x - 7)² = 49
x² + 4x² + 49 - 28x = 49
5x² -28x = 0
x ( 5x - 28) = 0
x = 0, x = 28/5
For x = 0, y = -7 (in eqn1)=>
(x, y) = (0, 7)
For x = 28/5
y = 2(28/5) - 7
= (56 - 35) / 5
= 21 / 5
(x,y) = (28/5 , 21/5)
Hence, (x, y) = (0, -7) and (28/5 , 21/5), as found by solving the system of linear equations.
