Answer:. 400%
Step-by-step explanation:
Divide 160 by 40.
The result is 4.
To Change to a percentage, multiply by 100.
4 × 100 = 400%
The integer number 40 will be 25 percent of the integer number 160.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The percentage of 40 out of 160 will be given as,
P = (40 / 160) x 100
P = 0.25 x 100
P = 25%
The integer number 40 will be 25% of the integer number 160.

A player in a board game rolls a six-sided
number cube labeled 1 through 6 once.
Determine the theoretical probability of
rolling a 1 or 2.
Answer:
A six sided number from 1 to 6 is rolled in a game.
Step-by-step explanation:
Theoretical probability of rolling a 1 or 2.
1) The cube has 6 faces so the total number of the outcome would be 6 only.
2) As per the question we need only 1 or 2 so the favorable outcome would be 2.
3) P(E) = favorable outcome/ total number of outcome
P(E) = 2/6
P(E) = 1/3
Theoretical probability of rolling a 1 or 2 is 1/3

−2 1/4=r−4/5
Help
Plz
Answer:
r=-29/20
Step-by-step explanation:
because
-2 1/4 will be -9/4=r-2/5 now you add 2/5 to both sides
witch means you have to increase the denominator to the greatest common denominator of 4 and 5 witch is 20 multiply the number used to combine with the denominator to get 20 to the numerator so itll be -45/20+16/20 witch will be -29/20 so there fore r=-29/20 or 1 9/20.

help what is the value of b?
Answer:
44 °
Step-by-step explanation:
180- (84+52) = 44
Answer:
44 degrees
Step-by-step explanation:
A triangle has a total of 180 degrees.
First, add the 2 sides that are given to you:
84 + 52 = 136 degrees
Subtract 136 from 180 to find the remaining angle:
180 - 136 = 44 degrees
b = 44 degrees

Does y = 2x + 4 show direct variation?
Answer:
no
Step-by-step explanation:
Direct variation is of the form
y = kx
This has a constant added
y = kx+b so it is not a direct variation
Answer:
NO
Step-by-step explanation:
in order for it to be a direct variation, "+4" must be out of the equation. y=kx

cancel out
−12=16
because −12=16 is false there is no solution.

the area of the triangle formed by points of intersection of parabola y=a(x-3)(x+2) with the coordinate axes is 10. find a if it is known that parabola opens upward
Answer
1/4 × 6 × (5a) = 12
15a=12
a= 4/5
Step-by-step explanation:
The area of the triangle formed by points of intersection of parabola y=a(x-3)(x+2) with the coordinate axes is 10. The constant (a) of the function is 4.
How to find the if the parabola is open?The triangle formed by the parabola has a base equal to the distance between the points where the graph touches the x-axis and height (h) is the point where the graph touches the y-axis.
The points on the x-axis are the roots of the quadratic equation:
a(x-3)(x+2)=0
(x-3)(x+2)=0
x - 3 = 0
x = 3
or
x + 2 = 0
x = -2
So, the base is the distance between (-2,0) and (3,0).
Since they are in the same coordinate, the distance here;
b = 3 - (-2)
b = 5
The area of the triangle is 10. So
5a = 10 x 2
a = 4
The constant (a) of the function y = a(x-3)(x+2) is 4.

Amanda's monthly salary increased from $5,300 to $5,538.50. Mary's salary also increased by the same percentage as Amanda's.
If Mary was earlier getting $6,300, what is her new salary?
Answer:
$6,583.5
Step-by-step explanation:
Amanda's monthly salary increased by 4.5%. You can get the percentage by getting the increased amount in salary and dividing it by the previous salary of Amanda.
$5,538.50 - $5,300 = $238.5$238.5 ÷ $5,300 = 0.045 (4.5%)In order to get the new salary of Mary, you have to multiply the same percentage, 4.5%, to Mary's previous salary, $6,300. This will give you the amount that will be added to her new salary.
$6,300 x 0.045 (4.5%) = $283.5$283.5 + $6,300 = $6,583.5Mary's new salary is $6,583.5

Which equation could represent the relationship shown in the scatter plot?
A: y=−3/4x+10
B: y=−3x−2
C: y=−2/3x+1
D: y=9x−1/2
Answer:
A
Step-by-step explanation:
Use POE, none of the answer makes any sense
Answer: The correct answer would be A
Step-by-step explanation:
This question asks us what equation could represent the scatter plot. While we may not be looking for an exact line of fit we want one that can best represent the data that we have. While I would highly recommend graphing each equation as it would give you a much greater understanding of the material you can also piece together a correct answer just by looking at the equations. First of all, by looking at the graph we can tell that the slope is negative because as we progress along the x axis the values on the y axis get lower and lower meaning that we have a downward sloping line. This immediately narrows out D because we can see that there is no - sign before the 9x which represents the slope. We can also narrow out B right away as the slope is too extreme for our scenario. A slope of -3 means that it would have to be a lot more vertical than we see represented in this scatter plot. -3 means that the line would have to go down 3 units for every 1 unit it horizontally moves if that makes sense. Now we are left with two possible answer choices, A and C. We can now look at the y intercept point of these equations to determine the best answer. The y intercept is the point at which the line crosses the y axis. C has a y intercept of 1 and we see the scatter plot points congregate much higher on the y axis than 1 so that rules out that answer leaving us with A! Just to double check our answer we know a slope of -3/4x seems reasonable based on the previous information and we can certainly see that a y intercept of 10 would make sense! I hope this has been of use to you and please do not hesitate if you have anything you would like me to elaborate on :) Have a wonderful rest of your day!
