Angles A and B are complementary. The measure of angle A is yº. What is the measure of angle B?

Mathematics
1 answer:
Nana76 [90]3 years ago
4 0

Answer:

D, (90-y) degrees

Step-by-step explanation:

Complementary angles are angles that add up to 90 degrees. Since angle A and angle B are complementary, they add up to 90. Since the value of angle A is y degrees, we can substitute y into the equation to get

y+B=90

To get the measure of angle B, we must isolate B.

To isolate B, we have to remove every term from its side.

The only term on the side that B is on other than B is y. To remove y from the left side, we must subtract y from both sides. Doing this will result in the equation:

B=90-y

The only answer option that meets this criteria is D.

14. The property tax on a medical center is 1 mill or no of a cent ($0.001)
mezya [45]

Answer:

a) $235.65

b) $57,499.58

Step-by-step explanation:

Tax rate is 1 mill or $0.001 on every $1 of appraised value. This means the tax rate is:

Tax rate = $0.001 per $1 = \frac{0.001}{1} \times 100\%=0.1\%

Part a)

Appraised value of medical center = $ 235,654

Tax rate = 0.1%

Tax Amount due = 0.1% of $ 235,65 = \frac{0.1}{100} \times 235,654= \$ 235.654

Thus, the tax due for 1 mill is $235.65 rounded to nearest cent.

Part b)

New Tax rate = 244 mills = \$ \frac{244}{1000} =$0.244

Tax rate is 1 mill or $0.001 on every $1 of appraised value. This means the tax rate is:

Tax rate = $0.244 per $1 = \frac{0.244}{1} \times 100\%=24.4\%

Tax Amount due = 24.4% of $ 235,65 = \frac{24.4}{100} \times 235,654= \$ 57499.576

Thus, the tax due for 244 mills is $57,499.58 rounded to nearest cent.

Naddik [55]

Step-by-step explanation:

The formula for the area of a square is:

A

=

s

2

Where:

A

is the area of the square.

s

is the length of the side of a square.

Substituting and solving for

s

gives:

225

cm

2

=

s

2

We can take the square root of each side of the equation giving:

√

225

cm

2

=

√

s

2

15

cm

=

s

s

=

15

cm

The formula for the perimeter of a square is:

p

=

4

s

Where:

p

is the perimeter of the square.

s

is the length of the side of a square.

Substituting for

s

from the solution for the previous formula and calculating

p

gives:

p

=

4

×

Is it possible for a system to have more than one solution? Explain your answer
Anastasy [175]
A linear system can have infinite solutions if both systems represent the same line. if a linear system down not represent the same line then it can only have one or no solutions. No solution is if the system is representing parallel lines and one solution represents an intersection of the two lines.  in a nonlinear system you can have infinite or up to a maximum of intersections as the highest degree of the systems.
