In a triple batch of a spice mix, there are 6 teaspoons of garlic powder and 15
teaspoons of salt. Answer the following questions about the mix.
2. How much salt is used with 8 teaspoons of garlic powder
3. If there are 14 teaspoons of spice mix, how much salt is in it.
4. How much More salt is there than garlic powder if 6 teaspoons of garlic powder are use
The answers of the given questions are:
8 teaspoons of garlic powder are combined with 20 tablespoons of salt.10 teaspoons of salt are included in every 14 teaspoons of spice mixture.If 6 teaspoons of garlic powder are used, there are 15 teaspoons more salt than garlic powder.What exactly are ratio and proportion?A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other. For example, if there is one boy and three girls, the ratio could be written as: 1: 3 (for every one boy, there are three girls).Given: There are 6 teaspoons of garlic powder and 15 teaspoons of salt in a triple batch of spice mix.
Let x be the teaspoons of salt.
Salt used with 8 teaspoons of garlic powder:
6/15 = 8/x
x = 20
Therefore, 20 teaspoons of salt is used with 8 teaspoons of garlic powder.
6 + 15 = 21 teaspoons of spice mix
Salt used in 14 teaspoons of spice mix:
21/15 = 14/x
x = 10 teaspoons of salt.
Therefore, if there are 14 teaspoons of spice mix, 10 teaspoons of salt is there in it.
If 6 teaspoons of garlic powder are used then,
21-6 = 15 teaspoons of more salt is used
Therefore, 15 teaspoons of more salt is there than garlic powder if 6 teaspoons of garlic powder are used.
The answers of the given questions are:
20 teaspoons of salt is used with 8 teaspoons of garlic powder.If there are 14 teaspoons of spice mix, 10 teaspoons of salt is there in it. 15 teaspoons of more salt is there than garlic powder if 6 teaspoons of garlic powder are used.Learn more about ratio and proportion here:

Please describe some of these new postulates and include a diagram on the whiteboard to help explain how they are applied.You have learned some new ways in this module to prove that triangles are similar Please describe some of these new postulates and include a diagram on the whiteboard to help explain how they are applied.
The Solution:
Required:
To use the three theorems of similarity:
There are 3 theorems for proving triangle similarity:
AA Theorem
SAS Theorem
SSS Theorem
SAS Theorem
What happens if we only have side measurements, and the angle measures for each triangle are unknown? If we can show that all three sides of one triangle are proportional to the three sides of another triangle, then it follows logically that the angle measurements must also be the same.
SSS Theorem
Or what if we can demonstrate that two pairs of sides of one triangle are proportional to two pairs of sides of another triangle, and their included angles are congruent?
AA Theorem
As we saw with the AA similarity postulate, it’s not necessary for us to check every single angle and side in order to tell if two triangles are similar. Thanks to the triangle sum theorem, all we have to show is that two angles of one triangle are congruent to two angles of another triangle to show similar triangles.

In order to add these two numbers, we need to add the algarisms that are in the same position.
Since the first number has 7 zeros and the second one has 8 zeros, the numbers 2 and 3 will not be added, since they are in different positions (the number 3 has more "value", since it's in a higher position).
So, adding these two numbers, we have:

Which equation best represents the graph above?
The equation is (x+1)²-4.
Here the graph is in the form parabola, where the parabola is basically a graph for a quadratic function which is a curve in such an order that a point on it is equidistant from a fixed point called the focus of the parabola, and a fixed line called the directrix of the parabola. The general formula for a parabola is: y = a(x-h)² + k , where (h,k) signifies the vertex whereas the standard equation of a parabola is y² = 4ax.
For the given graph the vertex is (h,k)=(-1,-4)
so the equation for the parabola is
=>y= a(x+1)^²-4 .......1
Since we can see the parabola intercept at the x-axis at point (1,0), putting those in the above equation :

attained by the arrow?
Answer: Maximum height reached is 804.88 m
Step-by-step explanation:
At maximum height velocity is zero
We have equation of motion v² = u² + 2as
Initial velocity, u = 320 ft/s = 97.536 m/s
Final velocity, v = 0 m/s
Acceleration, a = -9.81 m/s²
Substituting
v² = u² + 2as
0² = 97.536² + 2 x -9.81 x s
s = 484.88 m
So the arrow further a height of 484.88 m
Total height = 320 + 484.88 = 804.88 m

The given system of equations : 6x - y = 2 and 4x - y = -8.
6x - y = 2 ( 1 )
4x - y = -8 ( 2 )
for the value of y, use substitution method:
Solve the equation (1) for y :
6x - y = 2
y = 6x - 2
Susbtitute the value of y in the equation ( 2 )
4x - y = - 8
4x - (6x - 2) = - 8
4x - 6x + 2 = - 8
4x -6x = - 8 - 2
-2x = -10
Divide both side by ( -2)
-2x/(-2) = -10/(-2)
x = 5
Substitute x = 5 in the equation ( 1 )
6x - y = 2
6( 5 ) - y = 2

y = 30 - 2
y = 28
So, the value of y is 28

How to calculate the number of popcorn and drink?Liam went into a movie theater and bought 9 bags of popcorn and 8 drinks costing a total of $97.50. This will be:
9p + 8d = 97.50
Jacob went into the same movie theater and bought 5 bags of popcorn and 4 drinks, costing a total of $51.50. This will be:
5p + 4d = 51.50
where P = popcorn
d = drink
The equations will be:
9p + 8d = 97.50
5p + 4d = 51.50
Multiply equation i by 5
Multiply equation ii by 9
45p + 40d = 487.50
45p + 36d = 463.50
Subtract
4d = 24
Divide.
d = 24/4
d = 6
Drink = $6
Since 9p + 8d = 97.50
9p + 8(6) = 97.50
9p + 48 = 97.50
9p = 97.50 - 48
p = $5.50
