Step-by-step explanation:

Krystal Ball's pulse rate is 30% higher than its normal rate of 70bpm. What is her pulse rate? After
lying down it decreased 20%. What is her heart rate now?

Answers

Answer:  

Starting bpm = 91

Resting bpm = 72.8

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

Explanation:

A 30% increase is represented by the multiplier 1.30 because

100% + 30% = 1.00 + 0.30 = 1.30

So Krystal's initial heart rate is 1.30*70 = 91 bpm.

If you wanted, you can think of it like this

30% of 70 = 0.30*70 = 21 is added onto the initial 70 bpm to get 70+21 = 91 bpm.

-----------

To decrease by 20%, we use the multiplier 0.80 since

100% - 20% = 1.00 - 0.20 = 0.80

Losing 20% of something means we keep the remaining 80%

So,

80% of 91 = 0.80*91 = 72.8 bpm.

-----------

Here's one way to find the final bpm in one single line

1.30*0.80*70 = 72.8

in which you could write it like this

(1 + 0.30)*(1 - 0.20)*(70) = 72.8

The second way may be a bit longer, but I find it's more descriptive to see where the percentage increases vs percentage decreases are.

When solving an ______, use inverse operations to undo the operations.

Answers

Answer:

equation

Step-by-step explanation:

Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry. Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on.

[RevyBreeze]

Answer:

equation

Step-by-step explanation:

To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation. Performing the same operation on both sides of an equation does not change the validity of the equation, or the value of the variable that satisfies it.

Step-by-step explanation:

to find the perpendicular line then you have to find the negative reciprocal which is 2 and to get that you flip the fraction and change the sign so

(-1/2) → 2/1 or 2

the y-intercept coordinate is (0, 3) so the y-intercept is 3

Terry calculates how much wood he needs to build the desk shown in the diagram . He says the area is 600ft2

What error did terry make

Find the correct area and explain your answer

Answers

the correct area is 3600ft2

Answer:

He forgot to multiply by 1/2 when finding the area of the above triangle.

Now we find the correct area;

A = BH x 1/2 (formula for finding area of triangle)

A = 10 x 24 x 1/2

A = 240 x 1/2

A = 240/2

A = 120

Now the rectangle's formula which is just (W x L) where "w" is the width and "l" is the length;

A = W x L

A = 24 x 15

A = 360

Now we add both the sums of the two areas:

120 + 360 = 480 square feet, the information provided here is your explanation.

A stock rises in value from $20 to $40. Then it decreases in value from $40 to $20. Is the percentage increase from $20 to $40 the same as the percentage decrease from $40 to $20? Explain.

Answers

Answer:

No

Step-by-step explanation:

To find how much something is a percent of another number, divide it by said other number

20/40 = 0.5

0.5 × 100 = 50%

The first one is a 50% increase

Then, 40/20 = 2

2 × 100 = 200%

It is a 200% decrease

So no, because 50% doesn't equal 200%

Find the distance from point L to point M, if the point L has coordinates (-10,-9)

and the point M has coordinates (-2,6).

Answers

Answer:

The distance from point L to point M is 17

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is calculated as follows:

[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Point L has coordinates (-10,-9) and point M has coordinates (-2,6).

Calculate the distance between L and M:

[tex]d=\sqrt{(6+9)^2+(-2+10)^2}[/tex]

[tex]d=\sqrt{15^2+8^2}[/tex]

[tex]d=\sqrt{225+64}=\sqrt{289}[/tex]

[tex]\boxed{d=17}[/tex]

The distance from point L to point M is 17
