During a mayoral election, candidate A spent $960,000 on her campaign, and candidate B spent
$720,000 on her campaign. What is the ratio of candidate A's campaign spending to candidate
B's campaign spending?
Answer:
I think it is 4:3
Step-by-step explanation:
From $960,000 take away $720,000 and you get $240,000 and that $960,000 divide by $240,000 and you get 4 and you do the same with $720,000 and you get 3
The requried ratio of candidate A's campaign spending to candidate B's campaign spending is 4 : 3.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
here,
During a mayoral election, candidate A spent $960,000 on her campaign, and candidate B spent $720,000 on her campaign.
The ratio of candidate A's campaign spending to candidate B's campaign spending,
= 960000 / 720000
= 96 / 72
= 4 / 3
Thus, the requried ratio of candidate A's campaign spending to candidate B's campaign spending is 4 : 3.

The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients. Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 44 slices of bread and 69 slices of cheese. number of sandwiches: 22 Which of the two ingredients limits the number of sandwiches that can be made
Answer:
SLICE OF BREADStep-by-step explanation:
If a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, in order to determine the number of whole cheese sandwiches that can be prepared from 44 slices of bread and 69 slices of cheese, we will use the equality postulate as shown;
1 cheese sandwich = 2 slices of bread
x cheese sandwiches = 44 slices of bread
cross multiply
2 * x = 1 * 44
2x = 44
divide both sides by 2
2x/2 = 44/2
x = 22
Similarly;
1 cheese sandwich = 3 slices of cheese
y cheese sandwiches = 69 slices of cheese
cross multiply
3 * y = 1 * 69
3y = 69
divide both sides by 3
3y/3 = 69/3
3y = 23
Since both values of x and y are greater than or equal to 22 hence 22 sandwiches can be prepared from 44 slices of bread and 69 slices of cheese.
Since the amount of cheese sandwiches made from slices of bread (22) is not up to that made from slices of cheese (i.e 23), hence the ingredient that limits the number of sandwiches that can be made is the slice of bread

Based on the information marked in the diagram, ABC and DEF must be congruent.
True Or False?
Applying the HL congruence theorem, the information marked in the diagram cannot be congruent, so it is FALSE.
What is the HL Congruence Theorem?The HL congruence theorem states that if the corresponding legs of two right traingles are congruent, and the their hypotenuse are also congruent, then the triangles are congruent.
From the information given, we are not told if the hypotenuse of the right triangles are congruent, so we can't apply the HL congruence theorem to prove they are congruent. The answer is FALSE.

subtract 30 from 40 multiplyed by 3
Answer:
30-40=-10
-10x3= -30
Step-by-step explanation:
The point A has coordinates (-1, 6) and the point B has coordinates (7, 2).
i Find the equation of the perpendicular bisector of AB, giving your answer in the form y = mx + c.
ii A point C on the perpendicular bisector has coordinates (p, q). The distance OC is 2 units, where O is
the origin. Write down two equations involving p and q and hence find the coordinates of the possible
positions of C.
Answer:
a) y = 2x -2
b) Equation: q = 2p - 2 ----(1)
p² + q² = 4 ----(2)
The coordinates of C may be (0, -2) or (6/5, 8/5)
Step-by-step explanation:
a) Step 1: Find the coordinates of midpoint, P of AB
x-co-ordinate of P = (x₁ + x₂)/2 = (-1 + 7)/2 = 3
y- co-ordinate of P = (y₁ + y₂)/2 = (6 + 2)/2 = 4
Step 2: Determine the gradient, m₂ of perpendicular bisector of AB
For perpendicular lines, m₁ * m₂ = -1 where m₁ is slope of AB
m₁ = (2 - 6)/(7 - -1) = -4/8 = -1/2
-1/2 * m₂ = -1
m₂ = 2
Step 3: Deriving the equation of the perpendicular bisector in the form y = mx + c
y - y₁ = m(x - x₁); substituting the values of the midpoints of the line
y - 4 = 2(x - 3)
y - 4 = 2x - 6
y = 2x -2
b) Step 1: Derive the values of the p and using the formula of distance between two points:
y = 2x - 2
therefore q = 2p - 2 ----(1)
OC = √(x₂ -x₁)² + (y₂ - y₁)²
2 = √(p - 0)² + ( q - 0)²
2 = √p² + q²
squaring both sides
p² + q² = 4 ----(2)
Substituting (1) in (2)
p² + (2p - 2)² = 4
p² + 4p² - 8p + 4 = 4
5p² - 8p = 0
p(5p - 8) = 0
Therefore p = 0 or 5p - 8 = 0
p = 0 or p = 8/5
Substituting p = 0 in (1)
q = -2
substituting p = 8/5 in (1)
q = 2(8/5) - 2
q = 16/5 - 2
q = 6/5
Hence the coordinates of C may be (0, -2) or (6/5, 8/5)

Answer:
D. [tex] l = \frac{P - 2w}{2} [/tex]
Step-by-step explanation:
Given:
[tex] P = 2l + 2w [/tex]
Required:
Solve for l
Solution:
To solve for l, we would make l the subject of the given formula.
[tex] P = 2l + 2w [/tex]
[tex] P = 2(l + w) [/tex]
Divide both sides by 2
[tex] \frac{P}{2} = \frac{2(l + w)}{2} [/tex]
[tex] \frac{P}{2} = l + w [/tex]
Subtract w from both sides
[tex] \frac{P}{2} - w = l + w - w [/tex]
[tex] \frac{P}{2} - w = l [/tex]
[tex] \frac{P}{2} - \frac{w}{1} = l [/tex]
[tex] \frac{P - 2w}{2} = l [/tex]
Rewrite
[tex] l = \frac{P - 2w}{2} [/tex]

Which is the largest of the following numbers?
0.1, 0.02, 0.003, 0.0004, 0.00005
PLEASE HELP DUE TONIGHT!!! THANK YOU SO MUCH.
We need to use the place values to compare different numbers.
By only looking at the place value, we can see that the largest number is: 0.1
Let's see how to get the solution.
We can define place value as the place where a digit is with respect to the decimal point.
The digits that are at the far left are the larger ones, for example in:
11
The left one represents 10, while the right one represents 1:
10 + 1 = 11
The same happens when we look at the right of the decimal point, there the digits at the left will be larger than the ones at the right.
0.10 is larger than 0.01
From this, we can see that for the set:
{0.1, 0.02, 0.003, 0.0004, 0.00005}
The largest number will be the one with the leftmost first digit different than zero, which is the first one: 0.1
