Joes mother gave him 1/3 of the money in her purse. His father gave him 5.00. If they gave joe a total of 12.00, How much money did his mother have in her purse. Joes mother had $ money in her purse (Enter a number only and make sure to include the decimal and 2 numerical decimal places.)
Answer:
$21Step-by-step explanation:
let the money in her purse be $x
1/3 of the money is 1/3x
Since his father gave him $5 and the total amount became $12
the expression for the total amount would be
12= 1/3x+5
We can now solve for x
12-5= 1/3x
1/3x= 7
cross multiply we have
x= 7*3
x= $21
Therefore the money in joes mother's purse is $21

Find the distance between the points (4,10) and (0,0) the answer must be a whole number
Answer:
10.77
Step-by-step explanation:
√(4-0)²+(10-0)²
√4²+10²
√16+100
√116
10.77
Answer:
11
Step-by-step explanation:
For this problem, we simply need to apply the distance formula:
distance = sqrt[ (y2 - y1)^2 + (x2 - x1) ]
distance = sqrt[ (10 - 0)^2 + (4 - 0)^2 ]
distance = sqrt[ (10)^2 + (4)^2 ]
distance = sqrt[ 100 + 16]
distance = sqrt [ 116 ]
distance ~= 10.77
The approximate distance rounded to a whole number is 11.

Answer:
I believe it would be A
Step-by-step explanation:
Find the slope of the line parallel to the given line.
y= 2/5x+2
Slope:
[tex]\sf{\dfrac{2}{5}}[/tex]
Explanation:
Parallel lines have the same slope, so the slope of y = 2/5x + 2 will be the same as the slope of the line which is parallel to it.
The equation is written in slope-intercept form, aka y = mx + b, where m is the slope and b is the y-intercept.
In slope intercept, the slope is always the number that comes before x.
For this equation, the number in front of x is 2/5.
So, I come to the conclusion that the slope of the line parallel to y = 2/5x + 2 is 2/5.
If we decrease the time it takes for a car to travel over the same distance, this will (2 points) increase the speed have no effect on velocity or speed decrease the speed decrease the velocity
Answer:
Increase the speed
Step-by-step explanation:
The only way to decrease the time it would take to travel over a distance would be to increase the speed.
Answer:
see below
Step-by-step explanation:
if time decreases.... the velocity will decrease.
ex.
d = v/t
100 m = v/10 sec v = 1000 m/s
100 m = v/5 sec v = 500 m/s
100 m = v/1 sec v = 100 m/s
therefore,
if we decrease the time it takes for a car to travel over the same distance,
the velocity decreases too.

in a flowchart proof, _____ and ______ are connected with arrows ?
In a flowchart proof, statements and conclusions are connected with arrows.
In terms of mathematics, a statement is simply any sentence in which it can be verifiably true or false. A statement cannot be a subjective opinion. It must be an objective fact and there must not be any ambiguity involved. A conclusion is also a statement that derives from the first statement made.
As an example, you can have the simple argument "if it rains, then it gets wet outside". So the box on the left would be "it rains" and the box on the right would be "it gets wet outside". An arrow connecting the two shows the logical flow of how the argument is set up.
See the diagram below.
Side note: the box on the left is also considered the antecedent because it comes before the conclusion.

Somebody plz answer just number 15 and 13
Thank you!!
Answer:
13. 60
15. 200
Step-by-step explanation:
These are the answers because:
1) Since they are asking us to round to the tens place or the hundreds place we have to look at the ones digit and the tens digit.
2) For 13, the answer is 60 because the rounding digit is 5. Since the digit is 5, we have to round up the digit in the tens place. Therefore, it becomes 60.
3) For 15, the answer is 200 because the rounding digit is 3. Since the digit is 3, we have to keep the same number. Therefore, the answer is 200.

It cost Hudson $28.20 to send 188 text messages. How much would it cost to send 63 text messages? Good luck!
Answer:
$9.45
Step-by-step explanation:
1. First, you want to figure out how much one text message costs. To do this, divide the dollar amount (28.20) by the number of text messages (188). You get 0.15, or $0.15 per text message.
2. Using this $0.15 per text message, you can calculate how much 63 text messages costs. You simply multiply $0.15 by 63 to get $9.45, which is your answer.
Hope this helps! :)
When can you use proportional reasoning to solve a problem? A: When two quantities add to 1 B: When one quantity is a constant multiple of the other C: When the two quantities multiplied equal a constant D: When one quantity is 1 more than the other
Proportional reasoning is a form of 'operational reasoning' based on
Piaget's theory.
Proportional reasoning can be used to solve a problem; B. When one
quantity is a constant multiple of the other.
Reasons:
Proportional reasoning is the reasoning based on the cognition that a
relationship exists between the multiples of the variables in the problem,
such that the magnitude of a variable can implied from the changes made
to the relationships connecting the variables.
An example of proportional reasoning is the distance travelled, d, after a
given time, t, at a constant velocity, v;
d = v·tTo judge the distance travelled, a constant, v, multiplies the time, t, such
that, at a longer time, it can be reasoned that the distance travelled is
much further.
Therefore;
Proportional reasoning can be used to solve a problem in which one quantity is a constant multiple of the other.Learn more here:
https://brainly.com/question/11518481
Options B and C are the correct conditions under which you can use proportional reasoning to solve a problem:
Proportional reasoning is a mathematical concept that involves understanding and solving problems that relate two or more quantities in a proportional manner. It helps us analyze and predict how changes in one quantity affect another based on their proportional relationship.
B: When one quantity is a constant multiple of the other:
In this case, if one quantity is a constant multiple of another, it means that they are directly proportional. For example, if the quantity of oranges you buy is always twice the quantity of apples you buy, then the quantities of oranges and apples are directly proportional. Proportional reasoning can be used to solve problems related to this relationship.
C: When the two quantities multiplied equal a constant:
If the product of two quantities remains constant, regardless of their individual values, they are inversely proportional. For instance, if the time taken to complete a task is inversely proportional to the number of people working on it, as the number of people increases, the time taken decreases. Proportional reasoning can be used to solve problems involving inverse proportionality.
In summary, proportional reasoning is used when two quantities are directly or inversely proportional to each other, i.e., when one quantity is a constant multiple of the other or when the product of the two quantities remains constant.

to pass a course with an a grade a student must have an average of 90 or greater. a student's grade's on three tests are 83 91 and 86. find what score the student must get on the next test to get an a average
Answer:
90
Step-by-step explanation:
Find total marks needed for a 90.
90 x 4 = 360 marks
Then, add up the marks on the three tests.
83+91+86 = 260 marks
Finally, subtract from the 360 marks needed.
360 - 260 = 100
Thus, the student needs to score 100 marks in order to get a 90.

x=2/3
x=-3
x=3
Answer:
x=3
Step-by-step explanation:
Answer:
[tex]\boxed {\tt x=3}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]5x-2=3x+4[/tex]
We want to solve for x, therefore we must isolate x on one side of the equation.
First, move all the constants to one side of the equation. 2 is being subtracted from 5x. The inverse of subtraction is addition. Add 2 to both sides.
[tex]5x-2+2=3x+4+2[/tex]
[tex]5x=3x+4+2[/tex]
[tex]5x=3x+6[/tex]
Next, move all the terms with variables to one side. 3x is being added to 6. The inverse of addition is subtraction. Subtract 3x from both sides.
[tex]5x-3x=3x-3x+6[/tex]
[tex]5x-3x=6[/tex]
[tex]2x=6[/tex]
x is being multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.
[tex]\frac{2x}{2} =\frac{6}{2}[/tex]
[tex]x=\frac{6}{2}[/tex]
[tex]x=3[/tex]

Which equation represents a line which is parallel to the line y=-3/4 x -2
Answer: Any equation that is of the form y = -3/4x + b, where b is a real number, will be parallel to y = -3/4x - 2.
Step-by-step explanation:
A parallel line has the same slope as the original line. Therefore, if the equation of the original line is y = mx+b, m (the slope) will remain the same, while b can change.
The equation y = -3/4x - 2 has the same slope -3/4, represents a line which is parallel to the line y=-3/4 x -2
What is a linear function?A function that can be represented in the form of y =mx +c, is called a Linear Function. where m is the slope and c is the y-intercept.
The slope of the given line can be found as;
A parallel line has the same slope as the original line. Thus, if the equation of the original line is y = mx+b, m (the slope) will remain the same, while b can change.
Any equation that is of the form y = -3/4x + b,
where b is a real number, will be parallel to the equation.
y = -3/4x - 2.
m = -3/4
The equation y = -3/4x - 2 has the same slope -3/4, represents a line which is parallel to the line y=-3/4 x -2
