Answer:

Angle M = 63

Angle N = 96

Step-by-step explanation:

By exterior angle of triangle:

Angle M + Angle N = 159

(4y+3)+(6y+6)=159

y = 15

Angle M = 4y + 3 = 4(15) + 3 = 63

Angle N = 6y + 6 = 6(15) + 6 = 96

Answer:

[tex]Sum = -81[/tex]

Step-by-step explanation:

See the comment for complete question.

Given

[tex]c = 36[/tex] ----- Constant

No coefficient of x^2

Required:

Determine the sum of all distinct positive integers of the coefficient of x

Reading through the complete question, we can see that the question has 3 terms which are:

x^2 ---- with no coefficient

x ---- with an unknown coefficient

36 ---- constant

So, the equation can be represented as:

[tex]x^2 + ax + 36 = 0[/tex]

Where a is the unknown coefficient

From the question, we understand that the equation has two negative integer solution. This can be represented as:

[tex]x = -\alpha[/tex] and [tex]x = -\beta[/tex]

Using the above roots, the equation can be represented as:

[tex](x + \alpha)(x + \beta) = 0[/tex]

Open brackets

[tex]x^2 + (\alpha + \beta)x + \alpha \beta = 0[/tex]

To compare the above equation to [tex]x^2 + ax + 36 = 0[/tex], we have:

[tex]a = \alpha + \beta[/tex]

[tex]\alpha \beta = 36[/tex]

Where: [tex]\alpha, \beta <0[/tex] and [tex]\alpha \ne \beta[/tex]

The values of [tex]\alpha[/tex] and [tex]\beta[/tex] that satisfy [tex]\alpha \beta = 36[/tex] are:

[tex]\alpha = -1[/tex] and [tex]\beta = -36[/tex]

[tex]\alpha = -2[/tex] and [tex]\beta = -18[/tex]

[tex]\alpha = -3[/tex] and [tex]\beta = -12[/tex]

[tex]\alpha = -4[/tex] and [tex]\beta = -9[/tex]

So, the possible values of a are:

[tex]a = \alpha + \beta[/tex]

When [tex]\alpha = -1[/tex] and [tex]\beta = -36[/tex]

[tex]a = -1 - 36 = -37[/tex]

When [tex]\alpha = -2[/tex] and [tex]\beta = -18[/tex]

[tex]a = -2 - 18 = -20[/tex]

When [tex]\alpha = -3[/tex] and [tex]\beta = -12[/tex]

[tex]a = -3 - 12 = -15[/tex]

When [tex]\alpha = -4[/tex] and [tex]\beta = -9[/tex]

[tex]a = -4 - 9 = -13[/tex]

At this point, we have established that the possible values of a are: -37, -20, -15 and -9.

The required sum is:

[tex]Sum = -37 -20 -15 - 9[/tex]

[tex]Sum = -81[/tex]

Answer:

500,000 to 200,000 is a 60% decrease.

Step-by-step explanation:

volume of water flows through the pipe per second= π r² h = 22/7 × ( 3/4)² × 16

= 22/7 × 9/16 × 16

= 22/7 × 9

= 3.14 × 9 = 28.26 cm ³= 28.26/ 1000= 0.02826 litre

0.02826litre = 1 second

1 litre = 1 / 0.02826 = 100000/2826

= 35 .38 seconds

answer = 35.38 seconds

Answer:

Step-by-step explanation:

Did you mean: Change 19/4 into a mixed number (fraction).

How do you turn 19/4 into a mixed number?

As an improper fraction. (numerator larger than denominator): 19/4 = 19/4

As a mixed number (mixed fraction) (a whole number and a proper fraction, of the same sign): 19/4 = 4 3/4

As a decimal number: 19/4 = 4.75.

As a percentage: 19/4 = 475%

4 and 3/4

16/4 equals 4; then 19/4-16/4 = 3/4, so that's left over.

Answer:

All angles are different.

Internal angles can be acute, obtuse, or right angle.

The smallest side is opposite to the smallest angle and the longer side is opposite to the larger angle.

Step-by-step explanation:

Given - In ΔOPQ, PQ = 17, QO = 9, and OP = 15.

To find - Which statement about the angles of ΔOPQ must be true?

Proof -

As given,

In ΔOPQ, PQ = 17, QO = 9, and OP = 15.

As all the sides of the given triangle is different, So the given triangle is a Scalene triangle.

Now,

We know that , In Scalene triangle -

All sides are different.

All angles are different.

Internal angles can be acute, obtuse, or right angle.

The smallest side is opposite to the smallest angle and the longer side is opposite to the larger angle.

Smallest angle: ∠P

Opposite shortest side.

Middle angle: ∠O

Opposite middle side.

Largest angle: ∠Q

Opposite longest side.

Therefore:

m∠P<m∠O<m∠Q

Less than symbol goes from smallest to largest

Answer:

B, 6 inches

Step-by-step explanation:

The formula for area is width * height. If the area is the same in both times, increasing height means you must be decreasing width. B has a taller height so must have a shorter width.

7 and 1/2 = 15/2

45 / (15 / 2) = 45 * 2 / 15 = 6 inches
