What Is The Measurement Of Angle A?

Answers

Answer 1
The answer should b 55 degrees
Answer 2

Answer:

∠A  = tan⁻¹ (35/12) ≅  71.075 ° or 1.24 radians

Step-by-step explanation:

Since this is a right angled triangle, then we can use basic trigonometry to solve for ∠A.

We have the measure of the  side opposite (35) and adjacent (12) to ∠A.

Since tan(x) = opp/adj

 then tan (∠A) = 35/12

              ∴ ∠A  = tan⁻¹ (35/12)     [by taking the tan⁻¹ of both sides of the eq]

                  ∠A ≅ 71.075 ° or 1.24 radians

At school 40% of the teachers teach English if 20 teachers teach English how many teachers work at school

Answers

Answer:

Step-by-step explanation:

Change the 40% to a decimal, which is 40/100 or also equivalent to 2/5

Then divide the number of teachers by the percentage/decimal of teachers

20/(2/5) = 100/2 = 50 total teachers

The total number of teachers in the school is 50 teachers

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the total number of teachers in the school be = A

The percentage of teachers in the school who teach English = 40 %

The total number of English teachers = 20 teachers

So the percentage equation is ,

To calculate the total number of teachers

40 percentage of total teachers = 20 English teachers

So ,

( 40 / 100 ) x A = 20

Multiply by 100 on both sides , we get

40A = 2000

Divide by 40 on both sides , we get

A = 50

Therefore , the value of A is 50

Hence , the total number of teachers in the school is 50 teachers

SOLVE USING SUBSITUTION

Answers

Answer:

( 1, 5 )

x = 1

y = 1

Step-by-step explanation:

y = x + 4

2x + 3y = 17

Since they gave us the value of "y" we can use that and substitute it into the equation to find what "x" is.

2x + 3y = 17

2x + 3 ( x + 4 ) = 17

Distributive Property

2x + 3 * x + 3 * 4 = 17

2x + 3x + 12 = 17

Combine Like Terms ( 2x and 3x)

5x + 12 = 17

Subtract 12 on both sides of the equation

5x + 12 - 12 = 17 - 12

5x = 5

Divide by 5 on both sides to isolate the variable

5x/5 = 5/5

x = 1

Now that we have what "x" is, we can substitute that into one of the equations to get the value of "y"

y = x + 4

y = 1 + 4

y = 5

x = 1

y = 5

( x, y )

If Holly gets 14 % off a shirt , what percent of the original price will still pay​

Answers

Answer:

Holly will still pay 86% of the original price.

Step-by-step explanation:

Given

Holly gets 14% off a shirt, soDiscount = 14%

To determine

What percent of the original price will still pay.

All we need is to subtract the percentage of discount from 100.

i.e.

100 - Discount = 100 - 14 = 86%

The amount left over would be what remains of the original price after Holly gets 14 % off a shirt.

Thus, Holly will still pay 86% of the original price.

Which equation, together with y =-1.5x +3, makes a system with one solution?
A.
y =-1.5x + 6
B.
y=-1.5x
C.
2y =-3x + 6
D.
2y + 3x = 6
E.
y=-2x + 3

Answers

Answer:

Its would be E

Step-by-step explanation:

1.5x + 3 = -2x + 3    -1.5x = -2x   0.5x = 0  x = 0

Which is 0,3 and it’s only one solution.

The equation that gives the solution together with y = -1.5x + 3 is

y = -2x + 3

Option E is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 - 9 is an equation.

We have,

y = -1.5x + 3 ____(1)

y = -2x + 3 ____(2)

From (1 ) and (2) we get,

-2x + 3 = -1.5x + 3

-2x + 1.5x = 3 - 3

-0.5x = 0

x = 0

Now,

y = -2x + 3

y = 0 + 3

y = 3

Thus,

The solution is (0, 3).

Answers

Answer:

y = 42

Step-by-step explanation:

Since QT is a midsegment then it is half of RS , that is

QT = [tex]\frac{1}{2}[/tex] RS, substitute values

y = [tex]\frac{1}{2}[/tex] (y + 42) ← multiply both sides by 2 to clear the fraction

2y = y + 42 ( subtract y from both sides )

To shift a graph to the left you add to the x value

The answer would be B. g(x)=[1/2]×+3

The equation of g(x) = [1/2]x + 3 which is correct option (B)

What is translation of graph?

A translation of a graph is a shifting of the graph either horizontally or vertically parallel to the axis.

If g(x) was translated three units to the left to create f(x)= [1/2]x, then

g(x) - 3 = f(x)

g(x) = f(x) + 3 = [1/2]x + 3
