1/5 5/5 1
Answers
Answer:
5
Step-by-step explanation:
A reciprocal is the inverse of a fraction.
To find it just flip the numerator and denominator.
1/5 becomes 5/1, or 5.
The calculated reciprocal of the number 1/5 is 5
How to determine the reciprocal of the numberFrom the question, we have the following parameters that can be used in our computation:
Number = 1/5
By definition, the reciprocal of a number x is represebted as
reciprocal = 1/x
In this case,
x = 1/5
Substitute the known values in the above equation, so, we have the following representation
reciprocal = 1/(1/5)
Evaluate
reciprocal = 5
Hence, the reciprocal is 5

Two angles are complementary. The larger one is 3 times the measure of the
smaller one. What is the measure of the smaller angle in degrees?
Type just the numerical value.
Answers
Answer: 22.5°
Step-by-step explanation:
Complementary angles are the angles that when we add them together, they're equal to 90°.
Let the smaller angle be represented by x.
Then, the larger one will be 3 × x = 3x
We then add both angles together and equate them to 90°. Therefore,
x + 3x = 90°
4x = 90°
x = 90/4
x = 22.5°
The smaller angle is 22.5°

Which equation results from adding the equations in this system? 11 x minus 3 y = negative 17. Negative 4 x + 3 y = negative 18.
Answers
Answer:
7x = - 35
Step-by-step explanation:
Equation 1 :
11x - 3y = - 17
Equation 2 :
-4x + 3y = - 18
Equation 1 + 2
11x - 3y = - 17
-4x + 3y = - 18

Which values for A and B will create infinitely many solutions for this system of equations? A x minus y = 8. 2 x + y = B.
Answers
Answer:
A = -2
B = -8
Step-by-step explanation:
A system of equations has infinitely many solutions when both equations are exactly the same equation, then both graphs intersect in infinitely many points, meaning that the system has infinitely many solutions.
Then if we have the equations:
A*x- y = 8
2*x + y = B
We want to find A and B such that both equations are exactly the same thing.
Notice that in the first one we have negative y, while in the second we have positive y.
Then A needs to be minus the coefficient that multiplies x in the other equation, this means that:
A = -2
And B needs to be minus the corresponding therm in the other equation, then B = -8.
Then the system becomes:
-2*x - y = 8
2*x + y = -8
We can see that one equation is -1 times the other, so if we write both of them as linear equations in the slope-intercept form, we get:
y = -8 - 2*x
y = -8 - 2*x
So both equations are exactly the same thing, meaning that we have infinitely many solutions.

Answers
Answer:
im pretty sure the answer would be 40m
Step-by-step explanation:
Answer:
Area: 40m²
Step-by-step explanation:
The first thing we need to do in order to solve this problem is split the shape into three different rectangles. We are going to have one rectangle that is 3 m by 7 m, one that's 4 by 4, and one that is 3 by 1. We are now going to find the area of each one individually.
To find the area of a rectangle, you multiply the length by the width. So, for the first rectangle, you would multiply 7 and 3. This equals 21, so that is the area of the first rectangle. Repeat this for the other two rectangles, then add all the areas together and you will get the total area of this shape.
Remember, when you are finding the area of an object, you must always put the label and a squared sign next to the number!
7×3=21
4×4=16
3×1=3
21+16+3=40
Area = 40m²

Consider the following data set: {4, 5, 6, 7, 10}. If you remove one of the numbers from the list, then the mean increases and the median doesn’t change. Which number is it?
Answers
Answer:
6
Step-by-step explanation:
Right now, the mean is 6.4 and the median is 6. If you take away 6, the mean would be 6.5 and the median will stay the same. The median will stay the same because when there is no middle number, you add the two closest numbers and divide by two.
