Answer:

the answer is 2.87

Step-by-step explanation:

use the pythagorean theorem

2^2+b^2=4^2

that goes to b= 3.5

for the triangle with x you also need to use the pythagorean theorem

[tex]2^{2}[/tex]+[tex]x^{2}[/tex]=[tex]3.5^{2}[/tex]

4+[tex]x^{2}[/tex]=12.25

subtract 4 on both sides

[tex]x^{2}[/tex]=8.25

[tex]\sqrt{x}[/tex]=[tex]\sqrt{8.25}[/tex]

x=2.87

Answer:

[tex]\frac{4}{4} ,\frac{5}{5}[/tex]

Step-by-step explanation:

In order to find the answer to this question you need to remember that if the denominator and the numerator are the same they equal one or one whole.

[tex]\frac{2}{2} =1[/tex]

[tex]\frac{3}{3}=1[/tex]

[tex]\frac{4}{4}=1[/tex]

[tex]\frac{5}{5} =1[/tex]

As long as the numerator and the denominator are the same they will be equivalent to 2/2 and 3/3.

Hope this helps.

Answer:

∠ P = 40°

Step-by-step explanation:

Since PQ = PR then the triangle is isosceles and the base angles are congruent, then

∠ R = ∠ Q = 70° , so

∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°

∠ P = 180° - 140° = 40°

Answer:

x = ±9

Step-by-step explanation:

x² - 55 = 26

   +55   + 55

     x² = 81

     x = √81

     x = ± 9

Answer:

x = 9, -9

Step-by-step explanation:

x^2 - 55 = 26

x^2 = 81.

Now, you might think that x = 9, but don't be fooled. -9 squared is also equal to 81.

So, x = 9, -9

Answer: Y=4

Step-by-step explanation:

Answer:

The missing value is 3.

Step-by-step explanation:

I plugged in -2 as y.

-2 = -2x+4

-2 -4 = -2x -4

-6 = -2x

-6/-2 = -2x/-2

3 = x

So the point is (3, -2)

Answer:

There are many..

One would be y = 4x + 7

The trick is the slope is always the same. The only difference is the y-int. You could make one yourself, just use 4x at the beginning.

Answer:

  y = 4x

Step-by-step explanation:

A parallel line will have the same slope. The given line is written in "slope-intercept form", so the slope is readily identified from the equation.

  y = mx + b . . . . . line with slope m and y-intercept b

  y = 4x -7 . . . . . . line with slope 4 and y-intercept -7

So, the parallel line will be something of the form ...

  y = 4x + b

for any value of b. The simplest is to let b=0. If b=-7, then the lines are coincident, not parallel, so that value must be excluded. Any other value of y-intercept will give a parallel line.

  y = 4x . . . . . parallel line

Graph is a way to represent a lot of data in a visual formal. The graph that best represents the student's walk is graph A.

A graph is a way to represent a lot of data in such a visual formal that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

As we can see that the y-axis of the graph represents the distance traveled by the student while, the time taken by the student to cover the distance is given on the x-axis.

We know that the rate of 1.5 meters per second, means that the student will cover the 1.5 meters in 1 second, therefore, the line will be a slope that will represent the walk of the student. At time t=4 seconds, a student stopped for 4 seconds therefore, the time will increase but the distance will be constant for the student, therefore, the situation will be represented by a horizontal line.

Hence, the graph that best represents the student's walk is graph A.

If cell phone plan costs $0.20 cents per minute. Lisa has budgeted $35 a month for her cell phone then 175 minutes  Lisa can use each month

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that A cell phone plan costs $0.20 cents per minute.

Lisa has budgeted $35 a month for her cell phone.

We need to find  how many minutes Lisa can use each month.

Let us form a proportional equation to find this.

Let x be the number of minutes Lisa can use each month.

0.20/1=35/x

Apply cross multiplication

x=35/0.2

x=175

Hence, 175 minutes Lisa can use each month.
