If the measure of ABC = 91. What is the measure of QRS?

Answers

Answer 1
71 is the right answer
Answer 2

Answer:A normal QRS complex measures 0.06 to 0.12 seconds which is 1.5 to 3 small boxes on the EKG strip. When you measure the QRS complex you start by measuring at the END of the PR interval to the END of S-wave.

Describe two ways in which you can solve: [tex]-\frac{1}{2} (5x-9)=17[/tex]

Answers

Answer:

Method 1 is distribution of the -1/2 to 5x and -9. Method 2 is simplification by multiplying -1/2 to both sides of the equation.

Step-by-step explanation:

Method 1:                                   Method 2:

[tex]-\frac{1}{2} (5x-9)=17[/tex]                         [tex]-\frac{1}{2} (5x-9)=17[/tex]

[tex]-\frac{1}{2}[/tex](5x-9)=17                                [tex]-\frac{1}{2}[/tex](5x-9)=17                                

[tex]-\frac{1}{2}[/tex]*5x-([tex]-\frac{1}{2}[/tex]*9)=17                         [tex]-\frac{1}{2}[/tex]*(-2)(5x-9)=17*(-2)  

[tex]-\frac{5}{2}[/tex]x+([tex]\frac{1}{2}[/tex]*9)=17                               5x-9=-34

[tex]-\frac{5}{2}[/tex]x+9/2=17                                5x-9+9=-34+9

([tex]-\frac{5}{2}[/tex]x+9/2=17)*2                           5x=-25

-5x+9=34                                    5x/5=-25/5

-5x+9-9=34-9                              x=-5

-5x=25

-5x/(-5)=25/(-5)

x=-5

Use the expression 5x + 2y + 9 − 7 to identify: a. The terms, b. The coefficients, c. The constants.

Answers

The required answers are,

a. The terms - 5x, 27, 9, -7

b. The coefficients - 5 and 2

c. The constants - 9 and -7

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given expression is 5x + 2y + 9 − 7

Now the terms in the equation are 5x, 27, 9, -7

Therefore,

Terms = 5x, 27, 9, -7

Now coefficient is a number or any symbol representing a constant value that is multiplied by the variable.

So the variables in the given expressions are x and y.

And their multiples are 5 and 2, 5 is in multiplication of x and 2 is in multiplication of y.

Thus, coefficients are, 5 and 2

or, Coefficients = 5 and 2

Now th constants are the numbers that are not in multiplication with the variable. Thus, their value remains unchanged.

So in the given expression 9 and -7 are the constants that are not in multiplication with the variables.

Thus,

Constants =  9 and -7

Hence we get,

Terms = 5x, 27, 9, -7

Coefficients = 5 and 2

Constants =  9 and -7

Thus, the required answers are,

a. The terms -5x, 27, 9, -7

b. The coefficients - 5 and 2

c. The constants - 9 and -7

Answers

Orio and Ted buy an equal number of comic books every month. Orio has 9 more comic books than Ted.

What are a definition and an example of a linear equation?

A linear equation is an algebraic equation with each term having an exponent of 1, and a straight line is produced when the equation is graphed. Y=mx+b is an illustration of a linear equation.

The following equation shows the number of comic books, y, that Orio has after x months:

y = 2x + 15

Using the equation y=mx+b to find Orio's number of comic books, we can plug 2 months to substitute for the variable x.

y = 2(2) + 15

y = 4+15,

y = 19.

We know Ted has 10 comics after 2 months from the graph.

19-10= 9

Therefore, Orio has 9 more comic books than Ted.

Answers

35, ∠2 and ∠4 are alternate interior angles, so m∠2 = m∠4.

What is alternate interior angles?

Two angles that are on the interior of and, but on different sides of the transversal, are said to be alternate interior angles. The alternate interior angles theorem states that the alternate interior angles must be congruent if two parallel lines are cut by a transversal.

Given

           m∠4=35

From the image given, angle 2 and angle 4 lie on opposite side of the line that intercepts the two parallel lines, AB and CD. Angle 2 and angle 4 both lie within the parallel lines.

Therefore, ∠2 and ∠4  are alternate interior angles.

Thus,

m ∠2 = m∠4 (alternate interior angles theorem)

since m∠4 = 35°

therefore m∠2 = 35°

At the beginning of the fall, the water level of a lake is 11 1/3
feet below normal level. After a drought, the lake's water
level dropped 7 2/3 feet. Where is the lake's current water
level in relation to its normal water level?

Answers

The lake's current water is dropped ( 55 / 3 ) feet below the normal water level.

A collection of ordered pairs having one item from each set makes up a relation between two sets. If the ordered pair (x,y) is present in the relation and the objects x and y come from different sets, then the objects are said to be connected. One kind of relation is a function.

Let x be the normal water level of the lake.

At the beginning of the fall, the level of water of the lake is [tex]11\frac{1}{3}[/tex] feet below the water level.

So, the change in water level [tex]-11\frac{1}{3}[/tex].

Then, the water level of the lake dropped [tex]7\frac{2}{3}[/tex] feet after the drought.

Again, the change in water level will be [tex]-7\frac{2}{3}[/tex].

Hence, the total change in water level will be:

[tex]=-11\frac{1}{3}-7\frac{2}{3}[/tex]

= ( - 33 + 1 ) / 3 - ( 21 + 2 ) / 3

= ( - 32 / 3 ) - ( 23 / 3 )

= ( - 55 / 3 )

Therefore, the lake's water level dropped ( 55 / 3 ) feet below the normal water level.

The first term is 1. It appears that, to get each consecutive term, we have to multiply the previous term by -3.

i.e. 1 x -3 = -3-3 x -3 = 99 x -3 = -27

Therefore, to get each the next two terms, we have to multiply the previous term by -3.

a cell phone company charges an initial price of $400 for a new phone and then $50 each month after the purchase. if c (t) is a rational function that represents the average monthly cost of owning the cell phone, what is the range of the function? r: ℝ r: (–[infinity], [infinity]) r: (0, 400) r: (50, 450)

Answers

The range of the average cost function of a cell phone that has an initial and monthly costs $400 and $50 is r:(50, 400)

Which method can be used to find the range of the average cost function?

Initial price for the cell phone = $400

Charges per month after purchase = $50

The rational function representing the average monthly cost = c(t)

Required; The range of the average monthly cost function, c(t)

Solution:

The total cost of owning the cell phone, C, is therefore;

C = 400 + 50•t

Where;

∆t = The number of months after purchase

The average monthly cost is therefore;

[tex]c(t) = \frac{C}{ \Delta t} [/tex]

At ∆t ≈ 0, we have;

C ≈ 400

The cost for the month at ∆t ≈ 0, is therefore, c(t) = $400

At ∆t ≈ ∞, we have;

[tex] \lim\limits_{∆t→∞} \frac{400}{ ∆t} = 0[/tex]

Therefore;

[tex] \lim\limits_{∆t→∞} c(t) = \frac{400+ 50× ∆t}{ ∆t} ≈ 50[/tex]

Which gives;

The range of c(t) is (50, 400)

Answer:  D)  subtract 15 from both sides

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

Explanation:

15 - 2.5x is the same as 15 + (-2.5)x

Then we can swap the terms to get -2.5x+15

Therefore, the original equation is the same as -2.5x+15 = 40

To solve this equation, we follow PEMDAS in reverse. So instead of starting with the "P", we start with the "S". There's no subtraction operations to undo, so we move onto the "A". There is an additional operation to undo, which is the +15

To undo the +15, we subtract 15 from both sides

-2.5x+15 = 40

-2.5x+15-15 = 40-15

-2.5x = 25

The next step after this would be to divide both sides by -2.5 to undo the multiplication. The -2.5x means "-2.5 times x".
