What are the coordinates of the point on the directed line segment from (−4,10) to (-2, -2) that partitions the segment into a ratio of 3 to 1? HURRYYYY!!!!
Answers
Answer:
(-2.5 , 1)
Step-by-step explanation:
the x- coordinates :
[(3×(-2)) + (1×(-4))] /(3+1)
= (-6 +(-4))/(4)
= -10/4
= -2.5
the y-coordinates :
[(3×(-2)) + (1×10)] / (3+1)
= (-6+10)/(4)
= 4/4
= 1
so, the coordinates are (-2.5 , 1)
Answer:
(-2.5, 1)Step-by-step explanation:
Directed line segment from (−4,10) to (-2, -2).
The ratio = 3/1.
The coordinates are:
x = -4 + 3/4*(-2 - (-4)) = -4 + 3/4*(2) = -4 + 1.5 = - 2.5y = 10 + 3/4(-2 - 10) = 10 + 3/4*(-12) = 10 - 9 = 1

Find the measure of the smaller angle formed by the hands of a clock at the following time.
1:25
Answers
The smaller angle formed by the hands of a clock at the following time.
1:25 is 42.5 degrees and 107.5 degrees
What is total angle of a circle?360 degrees
We need to find the angles of clock at 1:25
At 1:25, the hour hand has moved 85 out of 720 possible times from the top of the clock. 85 times 0.5 degrees is 42.5 degrees.
At 1:25, the minute hand has moved 25 out of 60 possible times from the top of the clock. 25 times 6 degrees is 150 degrees.
150 - 42.5 = 107.5 degrees
Therefore the smaller angle formed by the hands of a clock at the time 1:25 is 42.5 degrees and 107.5 degrees

True/False Review and Chapter SummaryUse your knowledge of argument forms and the counterexample method to determine which, if any, of the following statements are true.Check all that apply.Every argument form is either a valid form or an invalid form.Counterexamples are used to prove the validity of an argument.When attempting to give a counterexample, you should substitute terms or statements that will yield premises and a conclusion with indisputable truth values.In an argument form for a hypothetical syllogism, the letters will stand for statements.A substitution instance with true premises and a true conclusion will not prove that an argument form is valid.A counterexample may have false premises and a false conclusion.A substitution instance is a representation of the logical structure of an argument using form words and letters.To represent the logical relationships in an argument, an argument form uses capital letters as a replacement for the meaningful content.Any set of sentences such that some are true and another is false is a counterexample to every invalid argument form.Not all valid arguments have the same argument form.Some valid arguments are substitution instances of invalid argument forms.If an argument is a substitution instance of both a valid argument form and an invalid argument form, then the argument is valid.Since it is impossible for the premises to be true and the conclusion to be false when an argument is valid, it follows that no counterexample can be given to a valid argument form.It is possible to give a counterexample to a valid argument that has false premises and a false conclusion.Some invalid arguments have valid argument forms.

Skye wants to buy 3 erasers each for her 4 best friends. If erasers cost $0.72 each, how much money does Skye need?
Answers
Answer:
3 x 4 = 12 erasers 12 x $0.72 = $8.64
Step-by-step explanation:
Answer: Skye will need $8.64
Step-by-step explanation:
We can start by seeing how many erasers she needs in total. We can multiply the 3 erasers for all 4 of her friends.
3 x 4 = 12 Erasers
Now we multiply the cost of one eraser by the total amount she needs, 12.
0.72 x 12 = 8.64
So the amount of money Skye needs for all her friends to have 3 erasers is $8.64

Marten bought 7 pairs of socks for $3 each, and a sweater for
for $12. Then he bought a $5 coffee, what was the change in
the amount of money Marten had?
Answers
Answer:
The total amount spent would be $38
Step-by-step explanation:
Because he bought 7 pairs of socks (each costing $3) for $21, a sweater for $12 and a $5 coffee. If we add the $21 (The cost of the socks) to the $12 (the cost of the sweater) and the $5 (the cost of the coffee) the total amount spent is $38. To find out the change given subtract $38 from the money he originally had

What is the radius of the circle? Example how you know..
Answers
Answer:
r=7
Step-by-step explanation:
C is at x=1 at circle side is at 8
8-1= 7
so, r=7
Answer:
The radius of the circle is 7 units.
Step-by-step explanation:
Radius is the measure from the center point of a circle to a point on the outside edge. Since you have coordinates, you can find the radius using distance formula.
You could also just count how many units are between the center and the edge to get 7 units because 8 - 1 = 7
The length of a rectangle is four times its width. If the perimeter of the rectangle is 50 in, find its area
Answers
Answer:
The perimeter of a rectangle is the sum of all of it’s sides. Since a rectangle has 2 lengths of the same size and two widths of the same size, the perimeter is length + length + width + width, or 2(length) + 2(width), or, to make it shorter, 2l + 2w.
Since the length of the rectangle (l) in this scenario is really 4w, we can replace those, and get 2(4w) + 2w, and since we know the total is 50, we can say 2(4w) + 2w = 50.
Using the distributive property, we get 8w + 2w = 50, and 10w = 50, or w = 5. Since the length is 4w, the length is 4*5 = 20.
To find the area, you multiply length and width to get 5 * 20 = 100 sq meters.

3 crates of cookies
were delivered One
crate hold 24 boxes of
cookies, with each box
containing 40 cookies
How many cookies ore
in the crate?
Answers
Answer:
990 cookies in one crate and 2880 cookies in all three crates combined.
Step-by-step explanation:
In each of the three crates are 24 boxes. First, let's find the number of boxes by multiplying:
3 crates x 24 boxes
3 x 24
72
So we have 72 boxes of cookies. Now we must complete the final step in order to calculate the number of cookies. We will do so by once again multiplying.
72 boxes x 40 cookies
72 x 40
2880
In total, that is, including all the cookies from all the boxes in all three crates, we have 2880 cookies.
The questions seems to ask how many cookies are in one crate, however. In order to find that, we must simply divide the number of cookies, 2880, by the number of crates, 3.
2880 cookies ÷ 3 crates
2880 ÷ 3
960
Therefore, there are 990 cookies in one crate and 2880 cookies in all three crates combined.
Answer:
A total of 2880 cookies in 3 crates.Step-by-step explanation:
Givens: 3 crates of cookies, crate hold 24 boxes of cookies, each box contains 40 cookiesOperation: MultiplicationSolution:24 × 40 = 960• There are 960 cookies in one crate.960 × 3 = 2880• Therefore, there are 2880 total numbers of cookies inside of 3 crates.[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]
