Answer: The equation that has resulted from this is 5x - 6.
Step-by-step explanation:
So far, we know that the givens are:
fives times a number and the difference of 6
Then, we can conclude that the term "a number" means an unknown term, so all we have to do is put a variable in its place. It can be k, s, h, z, x, etc. Next, just find the difference of 6. So, from what we know, this is what our new equation looks like:
5 times ( a number) - the difference of 6
In math form:
5 (x) - 6
Simplify:
5x - 6
Hence the answer!
a recipe for 1 loaf of bread calls for 2 cups of flour, 12 tablespoons of water, and 1 teaspoon of salt. The recipe can be scaled up to make multiple loaves of bread. Complete the table that shows the quantities to use for multiple loaves of bread.
Answer:
Step-by-step explanation:
A recipe for 1 loaf of bread calls for 2 cups of flour, 12 tablespoons of water and 1 teaspoon of salt.
Therefore, if we add 2 loaves of bread then double of ingredients will be required for the recipe.
In the same way if 4 loaves of bread have been added, 4 times ingredients will be required.
If 3 cups of flour are added then 3 times of other ingredients will be required.
So the table will be,

A runner gets a 30.0 meter head start then runs 5.0km/hr. Write an equation which will represent the runners distance from the start line at any second
Answer:
d = 1.4 t + 30
Step-by-step explanation:
Head start means any advantage achieved or advantage gained in any race or competition.
In the context, the runner is gained a head start of 30 meter from the starting point.
It is also given that the speed with which the runner is running is 5.0 km per hour.
Therefore, the equation that gives the distance covered by the runner from his start line at any time in seconds is given by d = 1.4 t + 30.

Answer:
0.37 feet.
Step-by-step explanation:
The following data were obtained from the question:
Volume (V) = 4100 ft³
Height (h) = 1.8 miles
Radius (r) =?
Next, we shall convert 1.8 miles to foot.
This can be obtained as follow:
Recall:
1 mile = 5280 ft
Therefore,
1.8 miles = 1.8 × 5280 = 9504 ft
Finally, we determine the radius as follow:
Volume (V) = 4100 ft³
Height (h) = 9504 ft
Pi (π) = 3.14
Radius (r) =?
V = πr²h
4100 = 3.14 × r² × 9504
4100 = r² × 29842.56
Divide both side by 29842.56
r² = 4100/29842.56
Take the square root of both side
r = √(4100/29842.56)
r = 0.37 ft
Therefore, the radius of the hole is 0.37 feet.
Daredevil Danny was cliff jumping. He jumped off a cliff that was 1 4 . 2 14.214, point, 2 meters above the surface of the water. At the end of his jump, Danny was 2 . 3 2.32, point, 3 meters below the surface of the water.
Question:
Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the water. At the end of his jump, Danny was 2.3 meters below the surface of the water.
The following equation describes this situation 14.2 + (-16,5) = -2.3 .
What does -16.5 tell us?
Answer:
The displacement between his current position and his initial position
Step-by-step explanation:
Given
[tex]Initial\ Position = 14.2m[/tex]
[tex]Final\ Position = -2.3m[/tex]
[tex]14.2 + (-16.5) = -2.3[/tex]
Required
What does -16.5 represents?
To understand this, we need to first calculate the displacement between his initial and final position
[tex]Displacement = Final\ Position - Initial\ Position[/tex]
[tex]Displacement = -2.3m - 14.2m[/tex]
[tex]Displacement = - 16.5m[/tex]
So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)

Put the numbers in scientific notation, with one digit left of the decimal point.
The number with the largest exponent is largest.
If exponents are equal, the number with the largest mantissa is the largest.

[tex](-7,4]\text{ or }\{x|-7<x\leq 4\}[/tex]
Step-by-step explanation:
The domain is the span of x-values covered by the function.
From the graph, we can see that the graph covers all the x-values from x=-7 to x=4.
However, note that closed and open circles. There is an open circle at x=-7, which means that the domain excludes x=-7. However, the circle at x=4 is closed, meaning it is included in the domain.
Therefore, the domain is, in interval notation:
[tex](-7,4][/tex]
We use parentheses on the left because we do not include -7. And we use brackets on the right because we do include the 4.
And in set notation, this is:

Find the area of the triangle below
Answer:
[tex]A=73.5\text{ cm}^2[/tex]
Step-by-step explanation:
The formula for an area of a triangle is:
[tex]A=\frac{1}{2}bh[/tex]
Where b is the base length and h is the vertical height.
From the triangle, we can see that the base is 21 cm while the vertical height is 7. Thus:
[tex]A=\frac{1}{2}(7)(21)[/tex]
Multiply:
[tex]A=\frac{1}{2}(147)[/tex]
Multiply:
[tex]A=73.5\text{ cm}^2[/tex]
And that's our answer :)
The Area of triangle is 73.5 square cm.
We have from the figure,
Base of triangle = 21 cm
Height of triangle = 7 cm
side of triangle = 15 cm
We know the formula for Area of Triangle
Area of Triangle = 1/2 x base x height
Now, plugging the value of base and height in the formula we get
Area of triangle = 1/2 x base x height
= 1/2 x 21 x 7
= 147/2
= 73.5 square cm

What is the arithmetic equation?Arithmetic is the fundamental branch of mathematics that covers number operations. Addition, subtraction, multiplication, and division are the operations involved.
The difference between each consecutive term in an arithmetic series is constant. The series 3, 5, 7, 9..., for example, is arithmetic because the difference between consecutive terms is always two.
Because the difference between subsequent words is always negative five, the sequence 21, 16, 11, 6... is also arithmetic.
Let the number added to 12 is x
Then,
12 + x = 36
x = 36 - 12 = 24
Therefore, the equation for the given calculation is 36 - 12 = 24.

The probability of spinning an even number on a spinner is 0.4. What is the probability of not spinning an even number, expressed as a percent?
Answer:
60%
Step-by-step explanation:
There are only even and odd numbers. If a number is not even, it is odd. If the probability of spinning an even number is 0.4, or 40%, then just subtract that by the whole spinner, which is equivalent to 100%:
100% - 40%
= 60%
This means that the odds of spinning an odd number is 60%

If given an equation of a line such as y = -1/2x + 6, demonstrate on the whiteboard how to create an equation of a line parallel and perpendicular to this line that goes through another point such as (4, 10).
Answer:
parallel line y = -1/2x + 12
perpendicular line y = 2x + 2
Step-by-step explanation:
slope = -1/2
perpendicular slope = 2
y = mx + b
10 = -1/2(4) + b
10 = -2 + b
12 = b
y = -1/2x + 12
10 = 2(4) + b
10 = 8 + b
2 = b
y = 2x + 2
During a fourth of July celebration, a cannon is fired upwards from Fort Ontario. The height, h, in feet, of the cannonball above sea level at any given time, t, in seconds, can be determined by the formula h = -16t2 + 120t + 200. Find the height, in feet, of the cannonball above sea level 5 seconds after the cannon is fired.
Answer:
400 feet
Step-by-step explanation:
We just need to find h when t = 5. To do so, we can plug t = 5 into the function, which would be:
h = -16t² + 120t + 200
= -16 * 5² + 120 * 5 + 200
= -400 + 600 + 200 = 400 feet
Answer:
h = 400 feet
Step-by-step explanation:
given t = 5 seconds
h = -16t² + 120t + 200
just substitute t = 5
h = -16(5)² + 120(5) + 200
h = 400 feet

A bag contains 8 red marbles, 7 blue marbles and 5 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that both marbles drawn will be green?
Answer:
Probability that both marbles drawn will be green = 1 / 20
Step-by-step explanation:
(It is assumed that marbles are not returned in the bag)
[tex]p(1st \: marble \: drawn \: is \: green) = \frac{5}{20} [/tex]
[tex]p(2nd \: marble \: drawn \: is \: green) = \frac{4}{20} [/tex]
