Answer:
1) c, f
2) a, e
3) b, d
Step-by-step explanation:
If you think about the units associated with a coordinate (feet, for example), then you may recognize the following
a) each difference is of "feet", so each difference will have units of "feet". The ratio of "feet" to "feet" cancels the units, leaving a pure number. In this case, it is called "steepness" in selection e. Steepness is given by the slope formula (2).
__
b) The difference in parentheses has units of "feet" (as in (a)), so the square will be "square feet". The sum of two of those will still be "square feet" and the square root of that will be "feet". The units of the formula are those of distance, or length, matching selection d. Distance is given by the distance formula (3).
__
c) The form shown is an ordered pair. That is the same as the representation of a coordinate point, selection f. Coordinates of a point are given by the midpoint formula (1).

Answers
Answer:
- 8/3
Step-by-step explanation:
Simply subtract 4 from 4/3
4/3 - 4 = 4/3-12/3=-8/3

I need the answer mate
Answers
Answer:
d
Step-by-step explanation:
The only viable solutions for the given condition are (4.5, 1.35) and (8, 2.40).
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Since the fee is charged at a rate of $0.30 per day, if a book is x days late, the total fee charged would be y = 0.30x.
We can check each ordered pair given to see if it satisfies this equation:
For (-3,-0.90), y = 0.30x = 0.30(-3) = -0.90.
This satisfies the equation, but the fee cannot be negative, so this is not a viable solution.
For (-2.5, -0.75), y = 0.30x = 0.30(-2.5) = -0.75.
Again, this satisfies the equation but the fee cannot be negative, so this is also not a viable solution.
For (4.5, 1.35), y = 0.30x = 0.30(4.5) = 1.35.
This satisfies the equation and the fee is positive, so this is a viable solution.
For (8, 2.40), y = 0.30x = 0.30(8) = 2.40.
This satisfies the equation and the fee is positive, so this is also a viable solution.
Therefore, the viable solutions are (4.5, 1.35) and (8, 2.40).

a garden contains 135 flowers, each of which is either red or yellow. there are 3 beds of yellow flowers and 3 beds of red flowers. there are 30 yellow flowers in each yellow flower bed.
Part A: if r represents the number of flowers in each red flower bed, what equation could you use to represent the number of red and yellow flowers.
Answers
Answer:
135 = 3y + 3r
y = 30; r = 15
Step-by-step explanation:
y = 3y + 3r
Where,
y = total number of flowers in the garden = 135
y = number of flowers in each yellow flower bed = 30
r = number of flowers in each red flower bed
135 = 3(30) + 3r
135 = 90 + 3r
135 - 90 = 3r
45 = 3r
r = 45/3
r = 15 flowers
number of flowers in each red flower bed = 15
Students running a food drive have collected their goal amount of canned goods. Over the weekend, volunteers collect an additional 18% of the goal. Write an expression to represent the total percentage of their goal collected in two different ways.
Answers
Answer:
[tex]Expression = x + 18x\%[/tex]
[tex]Expression = 1.18x[/tex]
Step-by-step explanation:
Given
Represent their goal with x
Additional = 18%
Required
Write two expressions to describe the total percentage
The expression is derived using:
[tex]Expression = Goal + Additional[/tex]
This gives:
[tex]Expression = x + 18\% * x[/tex]
[tex]Expression = x + 18x\%[/tex]
Solving further (Express percentage as decimal)
[tex]Expression = x + 0.18x[/tex]

SOH CAH TOA (if you don't just ask)
For 5: we have the adjacent and opposite side, we need the angle
I think here it's easiest to use TOA
so we have
tanx=60/70
take the arctan or tan^-1 and get
arctan(60/70)=x x= 40.6
For number 6 it's just the same deal
tanx=10/20
arctan(10/20) =x =26.57
For number 7 we have the adjacent side and we need to find the oppsoite side
for this I will once again use TOA
tan(48)=x/20

For number 8 it's the same deal as 7

Ray starts walking to school at a rate of 2 mi/h. Ten minutes later, his

to determine how much time it took Ray's sister to catch up to him.
Your answer
Answers
Answer:
Ray walks 15 minutes prior to his sister and walk for 5 minutes to catches up
Step-by-step explanation:
The computation of the time taken is as follows:
Let us assume the Ray time be t
So his sister time would be t - 10
Since Ray distance is 2t
So his sister distance is 6(t - 10) = 6t - 60
As the distance is the same
So, the following equation must be made
2t = 6t - 60
-4t = -60
t = 15
Therefore Ray walks 15 minutes prior to his sister and walk for 5 minutes to catches up

pythagorean theorem. and I need to calculate the missing sides. If possible I would like an explanation but an answer is also fine.
Answers
Answer:
Step-by-step explanation:
To calculate the missing sides square the side length of the legs of the triangles( the lines that form a 90 degree angle) then add them together, then take the sqr root of that to find the hypotunse( the slanted side). In simplier terms, here how it look.
[tex]a^{2}+b^{2} =c^{2}[/tex]
where a and b are the legs, and c is the hypotunese. For example, Ill do 3. The bases are 22, and 11 so plug them in the equations.
[tex]a^{2}+b^{2} =c^{2}[/tex]
11^2+22^2=c^2
121+484=c^2
605=c^2
c=about 24.6

Include all combinations in your answer, but include each combination only once be sure to indicate what your guess is.
Answers
Answer:
20 cents
Step-by-step explanation:
Possible coins in grandfather's pocket include : nickel, dime, quarter
A nickel = 5 cents
A dime = 10 cents
A quarter = 25 cents
First combination= nickel+dime+quarter+quarter
Second combination=nickel+quarter+quarter+quarter=
Third combination= dime+quarter+quarter+quarter
Third combination=quarter+quarter+quarter+quarter
4th combination = nickel + nickel+dime+quarter
5th combination= nickel +nickel+nickel+dime
6th combination =nickel+nickel+nickel+quarter
7th combination= nickel + nickel + nickel +nickel
8th combination = dime + dime +quarter +nickel
9th combination = dime +dime+dime+quarter
10th combination =dime+dime+dime+nickel
11th combination=dime+dime+dime+dime
If Grandpa offers to give you the coins if you are able to guess the amount within ten cents, then all coins are below ten cents and all coins are nickels = 4 nickels ×5 = 20 cents
