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?
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

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.

Find the measure of the smaller angle formed by the hands of a clock at the following time.
1:25
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

help me with this geometry
Answer:
x= (5X+3) DEGREES = 90 degrees (right angle)
5x=90 degrees - 3 degrees =87 degrees
5x÷5 =87 degrees ÷ 5
x=17.4 degrees
we now know our angles x = 17.4 degrees so we can know substitute into the give formula

Answer:
Step-by-step explanation:
Answer:
the numbers are 67 and 14
Step-by-step explanation:
let the other number be x
first number = 5x - 3
second number = x
5x - 3 + x = 81
6x = 81 +3
6x = 84
x = 84/6
x = 14
first number = 5x -3
= 5(14) -3
= 70 - 3
= 67
Second number = x

Which statement about the polygons is true?
Polygon A is similar to Polygon B because Polygon B is a reflection of Polygon A.
Polygon A is not similar to Polygon B.
Polygon A is similar to Polygon B because Polygon B is a dilation of Polygon A.
Polygon A is similar to Polygon B because Polygon B is a rotation of Polygon A.
Answer:
Your answer would be C. Polygon A is similar to Polygon B because Polygon B is a dilation of Polygon A.
Step-by-step explanation:
The shape is dilating (example: pupils growing larger or shrinking), it is not rotating, it is not a reflection, and it is not a rotation.
Polygon A is similar to Polygon B because Polygon B is a dilation of Polygon A. Then the correct option is B.
What is a polygon?The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
Polygon A and polygon B is shown.
There are four possible transformations of a point, line, or geometric figure, each of which changes the object's place or design.
Dilation is the technique of expanding an object's size without changing its shape. The size of the object can be increased or decreased according to the scale factor.
Polygon A is similar to Polygon B because Polygon B is a dilation of Polygon A.
Then the correct option is B.

Write an 11-digit number that uses every digit at least once, and the value of the digit in the millions place is 10 times the value of the digit in the hundred thousands place. Explain what you did.
An 11 digit number which is a solution to the problem Giveb is 32,561,100,000
All we have to do is write out an 11 digit number such that the value in the 1 million place is 10 times the value in the 100,000 place.
32,561,100,000
Writing the value given in expanded form :
3 in 10 billion place = 30,000,000,000
2 in one billion place = 2,000,000,000
5 in 100 million place = 500,000,000
6 in 10 million place = 60,000,000
1 in 1 million place = 1,000,000
1 in 100 thousand place = 100,000
Comparing the value in the 1 million place and that in the 100 thousand place :
1,000,000 / 100,000 = 10
This means that the value in the 1 million place is 10 times the value in the 100,000 place.
