2. In a triangle, the measure of the first angle is six times a number. The measure of the second angle is nine less than the first angle. The measure of the third angle is three times the number more than the measure of the first angle. Determine the measure of each angle in degrees.

Answers

Answer 1

The measure of the angle 1, 2, and 3 will be 54°, 45°, and 81°, respectively.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The initial angle of a triangle is measured by multiplying a value by six. The second angle's measurement is nine less than the first angle's. The third angle's measure is three times greater than the first angle's measurement. Let x be the number. Then the measure of the angle 1, 2, and 3 will be

∠1 = 6x

∠2 = 6x - 9

∠3 = 3x + 6x

The sum of all angles will be 180°, then the equation will be

∠1 + ∠2 + ∠3 = 180°

6x + 6x - 9 + 3x + 6x = 180°

21x = 189°

x = 9°

Then the measure of the angles will be

∠1 = 6x = 6 × 9 = 54°

∠2 = 6x - 9 = 6 × 9 - 9 = 45°

∠3 = 3x + 6x = 9x = 9 × 9 = 81°

Finding LCM for the problem, you should cut the cornbread into 6 parts, Sue will get 3 parts and Dena will get 2 parts.

LCM is referred to as the least common multiple for a set of numbers that can be divided by the same whole number as a result.

At first, we have to find LCM of 2 and 3, which is the denominator of 1/2 and 1/3, and its 6 and we will cut it into 6 pieces.

So, Sue will get 3 pieces from the cornbread ( 3/6 = 1/2 ) and Dena will get 2 pieces from the cornbread ( 2/6 = 1/3 ).

Answers

Answer:

(2, -3)

Step-by-step explanation:

x= -3y-7    

5x+6y=-8  

1. Substitute x= -3y-7 into 5x+6y=-8 which becomes

5(-3y-7)+6y=-8

2. expand the brackets

-15y-35+6y=-8

3. simplify the equation

 -9y-35=-8

4. from this we can find the value of y by adding 35 on each side and then dividing by -9 on each side

-9y=27

y=-3

5. so, the value of y is -3 to find the value of x we just substitute the value of y (-3) into the x=-3y-7

x= -3(-3)-7

expand the brackets and simplify the expression

x=9-7

Answers

True response is that the function represented by the graph is Increasing on (-∞, 0) and decreasing on (0, ∞)

A function is said to be increasing in its domains if the value of its range is increasing in that domain.

Similarly, if the function is decreasing in its domain then it's range must be decreasing with the domain.

When the value of x(domain) is increasing on the left side. The value of y(range) is increasing constantly. But when the value of x increases further after 0, then the value of y is decreasing constantly.

So we can say, the following function represented on the graph is increasing in the interval of ( -∞,0) and decreasing in (0,∞).

What is a square?

A square in geometry is a two-dimensional plane figure having four equal sides and four equal but 90 degree angles. The characteristics of a rectangle and a square are somewhat comparable, however only the opposite sides of a rectangle are equal. So, only if all four of a rectangle's sides are the same length can it be said to be a square.

A square is a regular quadrilateral with four equal-length sides and four equal-length angles. The square's angles are 90 degrees or at right angles. In addition, the square's diagonals are equally spaced and split at a 90-degree angle. A square is another name for a rectangle with two sides that are opposite and the same length.

The following is a list of a square's most significant characteristics:

The sum of the four inner angles is 90°.The square's four sides are equal to one another or congruent. The square's opposing sides run parallel to one another. The square's diagonals form a 90° angle with one another. The two diagonals of the square are equal to one another. The square is made up of four vertices and four sides. Two identical isosceles triangles are formed by the diagonal of the square. The square has longer diagonals than sides.

We know that,

Diagnose of a square are equal in magnitude and bisect each other.

So, In the given figure,

diagonals PR and QS are bisected at T.

RT = PT = 17

Hence,

PR=2RT=2*17=34

each day to meet his goal?

Answers

Answer:

Rahul needs to ride 3 miles a day to meet his target.

==============================

Given

Target distance = 22 miles,Distance already ridden = 10 miles,Time to travel the rest of the distance = 4 days,Average rate for 4 days = x miles.

We have the following linear equation to represent given situation:

22 = 10 + 4x

Solve it for x to get the average number of miles:

4x = 22 - 104x = 12x = 12/4x = 3

In linear equation, He ride 3 miles each day.

Variable: x = Constant distance distance traveled each day.

Equation : 10+4x= 22

What is a formula for linear equations?

Y = mx + b, where x and y are the variables, m is the slope of the line, and b is the y-intercept, is a straightforward way to write the linear equation formula. Slopes provide information about a line's direction and steepness.

Total distance needs to travel = 22 miles

Distance already traveled = 10 miles

He will ride bicycle for 4  more days.

Let x = Constant distance distance traveled each day.

Total distance = 10+4x

10+4x = 22

4x = 22 - 10

4x = 12

  x = 3

Hence, he rode 3 miles each day.

For each annual rate of change, find the corresponding growth or decay factor. +12.5 %

Answers

The growth factor for the annual rate of change of +12.5 % is 1.125.

A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.

With the function displayed to the right, you may represent exponential growth or decay.

A(x) = a( 1 + r)ˣ

Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.

Now, we have the annual rate of change as:

r = + 12.5 % = + 12.5 / 100 = + 0.125

From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.

So, let B = 1 + r

B = 1 + r

B = 1 + (+ 0.125)

B = 1.125

Now, the value of B is greater than 1 therefore, the corresponding growth factor is 1.125.

Based on Cameron's current music service fees, the number of songs that would make the new service a less expensive option is 101 songs

What number makes the service less expensive?

The expression for the new service assuming the number of songs is x is:

The expression for Cameron's current service is:

the equation for the parabola is:

f(x) = 2*(x + 4)*(x - 5)

How to write the equation for the parabola?

We know that if a parabola has x-intercepts a and b, and a leading coefficient A, then the equation is:

f(x) = A*(x - a)*(x - b)

In this case the x-intercepts are x = -4 and x = 5, then we have:

f(x) = A*(x + 4)*(x - 5)

Now we use the fact that the parabola passes through the point (1, -40), then we have that:

f(1) = -40 =  A*(1 + 4)*(1 - 5)

        -40 = A*(5)*(-4) = A*-20

Answer:

y = 105

x = 31

Step-by-step explanation:

We have y and 75 as consecutive interior angles.
(Consecutive interior angles are are found between the two parallel lines and on the same side of the transversal)

Sum of two consecutive interior angles = 180°

so we have y + 75 = 180
y = 180-75 = 105

So y = 105

y and (3x+12) are opposite angles and are equal
So 3x+12 = y
3x + 12 = 105
3x = 105-12 = 93
x = 93/3 = 31

So x = 31
