Find the measure of angle b

Answer:

Its 33,44,55.

Step-by-step explanation:

Answer:

"The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x)." 

Answer:

It is how steep a linear graph/function is.

Step-by-step explanation:

It is the m in the formula y=mx+b. The bigger the member the steeper.

Answer:

x is 10.

Step-by-step explanation:

3x + 12 = 42

Subtract 12 from both sides

3x = 42 - 12

Subtract 12 from 42 to get 30

3x = 30

Divide both sides by 3

x = 30/3

Divide 30 by 3 to get 10

x = 10

Here's how to solve the problem

Step-by-step explanation:

50% of participants are in 6th grade.

100% - 50% = 50

0.3, when converted to percentage form is 30%

50% - 30% = 20%

This remaining 20% is how many participants, out of the whole, are in the 7th grade

20% = 0.2 = 2/10 = 20/100

Answer:

(5,-2)

Step-by-step explanation:

Answer: 168.5 inches

50 yards = 1800 inches

50 meters = 1968.5 inches.

So, if you run 50 yards, you run 1968.5 - 1800, 168.5 inches less than 50 meters.

The number of bass are 9 and the number of trout are 3.

Given that, Pat was in a fishing competition at Lake Pisces. He caught some bass and some trout.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Let x be the number of bass and y be the number of trout.

Each bass weighed 3 pounds, and each trout weighed 1 pound. Pat caught a total of 30 pounds of fish.

So, 3x+y=30 --------(I)

Since trout are endangered in Lake Pisces, he lost 1 point for each trout. Pat scored a total of 42 points.

5x-y=42 --------(II)

Use elimination method

Add equation (I) and (II), we get

3x+y+5x-y=30+42

⇒ 8x=72

⇒ x=9

Put x=9 in equation (I), we get

3(9)+y=30

⇒ y=3

Hence, the number of bass are 9 and the number of trout are 3.

Answer:

Can you pls enter the correct question

Answer:

A. X < 3

Step-by-step explanation:

Let x represent the average number of shots Kaydence can take on each hole in order to beat Delilah's score.

Delilah final score is 42 while Kaydence has 5 holes left and has a score of 27. Hence:

number of holes left for Kaydence * x < Delilah final score - Kaydence present score

That is:

5*x < 42 - 27

Simplifying gives:

5x < 15

Dividing both sides by 5 to make x the subject of the inequality:

5x / 5 < 15 / 5

x < 3

Answer:

The person from the top was correct

Step-by-step explanation:

Answer:

Triangle P

Step-by-step explanation:

The solution to the system of equations 9x - 4y = 19 and 4x + 4y = 20

is x = 3 and y = 2.

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x - 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear.

Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, Two linear equations in two variables 'x' and 'y',

9x - 4y = 19 and 4x + 4y = 20.

Now, Adding these two equations we have,

13x = 39.

x = 3 and hence y = 2.

Joel need to practice this week = [tex]\frac{3}{4}[/tex] hour

Step-by-step explanation:

P.S - the exact question is -

As given

Total practice goal of Joel = [tex]4\frac{1}{2}[/tex] hours

He practiced on : Monday - [tex]1\frac{1}{2}[/tex] hours

                             Wednesday - [tex]1\frac{1}{4}[/tex] hours

                             Thursday - 1 hour

Let the remaining practice = x hours

⇒ Total practice =  [tex]4\frac{1}{2}[/tex] hours

⇒[tex]1\frac{1}{2}[/tex] + [tex]1\frac{1}{4}[/tex] + 1 + x = [tex]4\frac{1}{2}[/tex]

⇒ 1 + [tex]\frac{1}{2} + 1 + \frac{1}{4} + 1 + x = 4 + \frac{1}{2}[/tex]

⇒3 + x - 4 = [tex]\frac{1}{2} - \frac{1}{2} - \frac{1}{4}[/tex]

⇒x - 1 = [tex]-\frac{1}{4}[/tex]

⇒x = [tex]-\frac{1}{4} + 1 = \frac{-1 + 4}{4} = \frac{3}{4}[/tex]

⇒x = [tex]\frac{3}{4}[/tex] hour

∴ we get

Joel need to practice this week = [tex]\frac{3}{4}[/tex] hour

The distance that the base of the telephone pole to point B where the guy wire is secured to the ground is 57.7 feet

Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.

Given that triangle ABC is a right triangle.

Point A is the top of the telephone pole.

Point B is the point on the ground.

Point C is the base of the telephone pole.

Given,

AB = 79 feet

AC is the height of the telephone pole = 54 feet

Angle C is a right angle.

Using Pythagoras theorem,

(AB)² = (AC)² + (BC)²

79² = 54² + (BC)²

(BC)² = 79² - 54²

(BC)² = 3325

BC = √3325 = 57.66 ≈ 57.7 feet

Hence the length of the base of the pole form the ground where the wire is secured is approximately 57.7 feet.
