Step-by-step explanation:

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 of the following is the reciprocal of 1/5 ?
answers
5
1/5 5/5 1

Answers

Answer:

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 number

From 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

Step-by-step explanation:

for the first three rooms,

for the next two rooms,

area= 6l² = 6×15² = 1350

total area = 3084

Martha was making apple tarts. She added 1/2 cup of sugar in the beginning. Later, she added another 1/4 cup of sugar. Martha estimated that she added about 1/6 cup of sugar in all. Is Martha's estimate reasonable?

Answers

Answer: her answer is NOT reasonable because 1/2 is bigger that 1/6. The real addition to 1/2 and 1/4 is 3/4.

Step-by-step explanation:

1/2 is 2/4 and 1/4 stays the same because it is the common denominator

Add them and you get 3/4

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

So both equations are exactly the same thing, meaning that we have infinitely many solutions.

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:

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.
