Before running in a 100-m race, Gaalen's heart rate was
70 beats/min. Which do you think is more likely after the race:
60 beats/min or 120 beats/min? Explain.

Answer:

- [tex]\frac{27}{25\\}[/tex]

Step-by-step explanation:

4x−5y=39

for x=3

12 - 5y = 39

-5y = 39 -12

-5y = [tex]\frac{27}{5\\}[/tex]

-y = [tex]\frac{27}{25\\}[/tex]

y = - [tex]\frac{27}{25\\}[/tex] = -1 [tex]\frac{2}{25\\}\\[/tex]

-27/5 or -5 2/5

Step-by-step explanation:

4x-5y=39 while x=3

4(3)-5y=39 add x into bracket

12-5y=39 result of 4*3

12-5y-12=12-39 substrate non variable number to each side

5y = -27 the result from upper substraction

y= -27/5 the result mixed fraction form -5 2/5

Answer:

Step-by-step explanation:

Step one:

given data

the brown family has 5 liters of lemonade that weighs 1 kg per liter

this implies that they have 5kg of lemonade.

convert 5kg to grams we have 5*1000= 5000grams

(because 1000g is equal to 1kg)

Step two:

if at the end of the day there was 290grams left, then they drank

=5000-290

=4710

They drank 4710grams of lemonade.

Answer:

A

Step-by-step explanation:

Use the method of completing the square to express in vertex form.

Given

y = x² - 6x + 11

To complete the square

add/subtract ( half the coefficient of the x- term )² to x² - 6x

y = x² + 2(- 3)x + 9 - 9 + 11 , then

y  = (x - 3)² + 2 → A

Answer:A

Answer:

  0.579

Step-by-step explanation:

You can consider what the offered numbers are when they are rounded to hundredths:

  0.574 ⇒ 0.57

  0.579 ⇒ 0.58 . . . matches your requirement

  0.585 ⇒ 0.59

  0.681 ⇒ 0.68

The only number on the list that matches your rounding requirement is 0.579.

Answer:

x = -4

Step-by-step explanation:

Answer: -4 is correct

Step-by-step explanation:

Answer:

32.8

Step-by-step explanation:

The average is calculated as

average = [tex]\frac{sum}{count}[/tex]

let x be the fourth number, then

[tex]\frac{24.2+14.5+50.5+x}{4}[/tex] = 30.5 ( multiply both sides by 4 )

89.2 + x = 122 ( subtract 89.2 from both sides )

x = 32.8

Thus the fourth number is 32.8

Answer:

f(x) = (x + 4)² - 4

Step-by-step explanation:

Write the equation f(x) = x² + 8x + 12 in vertex form by completing the square:

f(x) = (x² + 8x + (8/2)²) + 12 - (8/2)²

Simplify:

f(x) = (x² + 8x + 16) + 12 - 16

Subtract to find the 'k' value:

f(x) = (x + 4)² - 4. This is the equation in vertex form.

Answer:

y=8x2+8x−12

Step-by-step explanation:

Rewrite in vertex form and use this form to find the vertex (h,k).

Answer:

See Explanation

Step-by-step explanation:

See attachment for complete question.

From the attachment, we have that:

[tex]A = 71[/tex]

[tex]C = 121[/tex]

[tex]T = 66[/tex]

First, we calculate the total

[tex]Total = A + C + T[/tex]

[tex]Total = 71 + 121 + 66[/tex]

[tex]Total = 258[/tex]

Solving (a): Probability of A

This is calculated using:

[tex]Probability = \frac{A}{Total}[/tex]

[tex]Probability = \frac{71}{258}[/tex]

[tex]Probability = 0.275[/tex]

Solving (b): Probability of C

This is calculated using:

[tex]Probability = \frac{C}{Total}[/tex]

[tex]Probability = \frac{121}{258}[/tex]

[tex]Probability = 0.469[/tex]

Solving (b): Probability of T

This is calculated using:

[tex]Probability = \frac{T}{Total}[/tex]

[tex]Probability = \frac{66}{258}[/tex]

[tex]Probability = 0.256[/tex]

Answer:

Step-by-step explanation:

Answer:

∠ 1 = 136°

Step-by-step explanation:

The diagonals of a rhombus bisect the angles, thus other side of the diagonal to 22° is also 22°. Making the whole angle = 44°

Consecutive angles are supplementary, thus

∠ 1 + 44° = 180° ( subtract 44° from both sides )

∠ 1 = 136°

Step-by-step explanation:

plz mark brainlyest

The probability of one who is more likely to brush both time morning and evening is Braxton, he has a 0.61 probability of brushing both times.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

The probability of Braxton brushing both times = (0.72×0.85) = 0.612

The Probability of Arabella brushing both times = (0.82×0.79) = 0.6478

Hence, the probability of one who is more likely to brush both time morning and evening is Braxton, he has a 0.61 probability of brushing both times.

Answer:

hat=£(9*9)/3*24)/3/8/9

Scarf=£1.5

Step-by-step explanation:

Let's suppose hats is the variable h

And Let's suppose scarves is the variable s

3h+2s=12

5h+4s=21

so, 3h+2s=12 which is also 2s=12-3h

so, in the equare 5h+4s=21 we can replace the 4s with 2(12-3h) Now the equation is this:

5h+24-6h=21

*Simplified*

Now 5h-6h= -1h

-1h+24=21

+1h      +1h

on each side.

now the equation is(remember 1h=h): 24=h+21

I think you can do it now.

Now with the cost of the hats, we can use the first equation: 3h+2s=12

h=3

Answer:

y= -5x-5

Step-by-step explanation:

Y is equal to 5 less than -5 times x, which means it is 5 less than -5x.

If y is 5 less than -5x, that means it is equal to -5x-5.

If you were to put that in an equation, it would be y= -5x-5

Answer:

It would be 2x -5=y

Step-by-step explanation:

The equation for the two points is 2x -5=y so the slope intercept would be 2x -5=y

Judy scored 45 points in the board game.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

In a board game,

Judy scored 5 points, more than twice the number of points Ann scored.

If Judy scores x points and Ann scores y points,

that means,

x = 2y + 5

x - 2y = 5.   {equation 1}

There was a total of 65 points scored.

x + y = 65  {equation 2}

Subtract the equation 2 to equation 1,

we get,

-3y = -60

y = 20

Then, x = 45.

Therefore, 45 points Judy scored.

Step-by-step explanation:

Answer:

Initial money -->$846,375,593

You spend 250,678 dollars on shoes, 10,008 dollars on clothes, and 40,034 dollars on accesories.

$846,375,593-$250,678-$10,008-440,034 = $845,674,873

Later, your friend and you get robbed and the robber takes half of the remaining money. How much do you have left?

$845,674,873/2 = $422,837,436.5

You have $422,837,436.5 left.

Answer: Ok look at the explaination

Step-by-step explanation:

$846,375,593 - everything you spend = 846,074,873

You both have 846,074,873 after the shopping spree

To calcute how much is left after the robbery you divide the money you have left by two since the robber took half. Then your are left with 423,037,436

Then you earn money so add 234,458.78 to your 423,037,436 and you have 423,271,922

At the end you are left with $423,271,922

Distance between points =  [tex]37/64\\[/tex]

Step-by-step explanation:

This is a relatively simple problem. Here we have to find the distance between two points on the number line.

The given two numbers are fractions and to find the difference between these two numbers, we have to make their denominators common.

One has denominator as 8 and the other as 64.

We make the common denominator as 64.

Then the fractions 24/64 are 61/64  and .

The distance between the two points = 61/64  - 24/64  

                                = 37/64

tsp of red food coloring = 25

Step-by-step explanation:

Red food coloring = 5 tsp

Blue food coloring = 3 tsp

Red food coloring : Blue food coloring = 5 tsp : 3 tsp

Blue food coloring = 15 tsp

how many tsp of red food coloring would you use to get the same recipe of frosting ?

Let

x = tsp of red food coloring

Red food coloring : Blue food coloring = x tsp : 15 tsp

Equate the ratios to find x

Red food coloring : Blue food coloring

5 tsp : 3 tsp = x tsp : 15 tsp

5 / 3 = x / 15

Cross product

5 * 15 = 3 * x

75 = 3x

Divide both sides by 3

x = 75 / 3

= 25

x = 25 tsp

tsp of red food coloring = 25
