The equation Choose can be used to determine the value of the number of months Isabella has been a member of the fitness club. She has been a member of the fitness club for Choose months.

**Answer: 19 months**

**Step-by-step explanation:**

**given data:**

**amount paid initially when joining the club = $50.**

**monthly payments made = $10.**

**total amount paid since joining the club = $240.**

**Solution:**

**= 10X + 50 = 240**

**collect like terms**

**= 10X = 240 – 50**

**10X = 190**

**divide both sides by 10**

**10X/10 = 190/10**

**X = 19**

**isabella has been a member of the club for 19 months.**

I'm doing sine, cosine, and tangent and I don't know what an opposite is in the triangle so if anyone can explain it in the most simple terms possible, that'd be great

**Step-by-step explanation:**

okay so basically when you have a triangle, the side that is directly across from the angle you are looking for is the "opposite". here is an attachment.

Answer:

A side opposite of an angle in a triangle is the angle that’s not adjacent to it.

In other words, an angle will touch 2 sides in a triangle. The one it doesn’t is the opposite angle.

The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. Here are data for beak heat loss, as a percent of total body heat loss, at various temperatures in degrees Celsius:

Temperature (degrees Celsius) 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Percent heat loss from beak 35 36 38 28 41 43 55 46 39 54 45 58 60 56 62 67

a. The equation of the least-squares regression line for predicting beak heat loss, as a percent of total body heat loss from all sources, from temperature is: _____ (Use decimal notation. Give your answer to four decimal places.)

b. Use the equation to predict (

Â±

0.01) beak heat loss, as a percent of total body heat loss from all sources, at a temperature of 25 degrees Celsius.

c. What percent (

Â±

0.01) of the variation in beak heat loss is explained by the straight-line relationship with temperature?

d. Find the correlation r (

Â±

0.001) between beak heat loss and temperature.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

Temperature (degrees Celsius) : 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Percent heat loss from beak : 35 36 38 28 41 43 55 46 39 54 45 58 60 56 62 67

Using an online regression calculator ; the regression equation obtained is :

ŷ = 2.0927X + 0.6029

X = independent variable

Y = predicted variable

2.0927 = slope

0.6029 = intercept

B.) temperature = 25

ŷ = 2.0927(25) + 0.6029

= 52.9204

C.) the explained variance is the value of the coefficient of determination (R²) which is the square of the correlation Coefficient

0.8785² = 0.7718

D.) the correlation Coefficient r is 0.8785 using the Coefficient of regression calculator

Tara's website, verdantveggies.com, specializes in the sale of rare or unusual vegetable seeds. Tara sells packets of sweet-pepper seeds for $2.85 each and packets of hot-pepper seeds for $4.29 each. She also offers a 16-packet mixed-pepper assortment combining packets of both types of seeds at $3.30 per packet. How many packets of each type of seed are in the assortment?

**Answer:**

Let's define the variables:

S = # of sweet pepper seeds in the mix pack.

H = # of hot pepper seeds in the mix pack.

Let's suppose that $3.30 is the mean price of the seeds in the mix pack.

Then we have two equations:

S + H = 16.

(S*$2.85 + H*$4.29)/16 = $3.30

Now let's solve this system.

The first step is isolating one variable in one of the equations, i will isolate S in the first equation.

S = 16 - H.

Now we can replace this in the second equation, and solve it for H.

( (16 - H)*$2.85 + H*$4.29)/16 = $3.30

( (16 - H)*$2.85 + H*$4.29) = $3.30*16 = $52.80

$45.60 + H*$1.44 = $52.80

H*$1.44 = $52.80 - $45.60 = $7.20

H = $7.20/$1.44 = 5

Then in the mix pack there are 5 hot-pepper seeds.

And the other 11 must be sweet-pepper seeds

**Algebraic equations **are equations that contain **unknown variables.**

The* number of packets of sweet-pepper seeds* is **11 **and the *number of packets of hot-pepper seeds* is **5. **

Let's represent:is

The number of packets of sweet-pepper seeds =** s**

The number of packets of hot-pepper seeds =** h**

Based on this question, our system of equations are:

$2.85 x s + $4.29 x h = $3.30(16)

**2.85s + 4.29h = 52.8...........Equation 1**

**s + h = 16...........Equation 2**

**s = 16 - h**

We substitute 16 - h for s in Equation 1

2.85(16 - h) + 4.29h = 52.8

45.6 -2.85h + 4.29h = 52.8

Subtract 45.6 from both sides

45.6 - 45.6 -2.85h + 4.29h = 52.8 - 45.6

1.44h = 7.2

**h = 5**

There are *5 hot-pepper seeds* in the assortment.

Solving for the number of sweet-pepper seeds.

s = 16 - h

s = 16 - 5

**s = 11**

There are *11 sweet-pepper seeds* in the assortment.

Therefore, *the number of packets of sweet-pepper seeds* is **11 **and the *number of packets of hot-pepper seeds* is **5. **

bob is on his way home in his car. he has driven 30 miles so far, which is three-fifths of the way home. what is the total length of his drive?

The length of Bob's drive as a fraction = 5/5

Let the length of his total drive be = x

30 miles driven by Bob as a fraction =

= 3/5 of x = 30

= 3/5x = 30

= 5/x = 30 ÷ 3 ( transposing ×3 from LHS to RHS changes ×3 to ÷3 )

=5/x = 10

= x = 10 × 5 ( transposing ÷5 from LHS to RHS changes ÷5 to ×5 )

= x = 50

Now we have to see what is =

= 2/5 of 50

= 2/5 × 50

= 100/5

= 20 miles

So , total length of Bob's drive = 30 miles + 20 miles = 50 miles .

∴ The total length of Bob's drive is **50 miles .**

Solve for X please :(( Will give brainliest.

5x+6+92 = 22x-4

5x+98 = 22x-4

add 5x to both sides

98 = 27x-4

add 4 to both sides

102 = 27x

divide both sides by 27

x = 3 and [tex]\frac{7}{9}[/tex]

175 students enrolled in a freshman-level chemistry class. By the end of the semester, 4 times the number of students passed as failed. Find the number of students who passed, and the number of students who failed.

**Answer:**

35 failed and 140 passed

**Step-by-step explanation:**

Let p = number who passed

f = number who failed

p+f = 175

4 times the number of students passed as failed, so we need to balance this to set it equal

4f = p

Substitute this into the first equation

4r+f = 175

5f = 175

5f/5 =175/5

f = 35

Now find the number who passed

p = 4f

p = 4*35

p =140

2/15 = h/125 need a step by step please

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

Work Shown:

2/15 = h/125

2*125 = 15*h .... cross multiply

250 = 15h

15h = 250

h = 250/15

h = (5*50)/(5*3)

**h = 50/3**

-----------------

Extra info:

50/3 = (48+2)/3

50/3 = (48/3)+(2/3)

50/3 = 16 + (2/3)

50/3 = 16 & 2/3

The improper fraction 50/3 converts to the mixed number 16 & 2/3

Another way to see this is to use long division to get 50/3 = 16 remainder 2.

Show that each conjecture is false by finding a counterexample.

1.For any integer n, n3 > 0.

2. Each angle in a right triangle has a different measure.

3.For many years in the U.S, each bank printed its own currency. The variety of different bills led to widespread counterfeiting. By the time of the Civil War, a significant fraction of the currency in circulation was counterfeit. If one soldier had 48 bills, 16 of which were counterfeit, and another soldier had 39 bills, 13 of which were counterfeit, make a conjecture about what fraction of bills were counterfeit at the time of the Civil War.

**Answer:**

1. [tex]n: n^3 > 0[/tex]* is not true for negative integers*

2. [tex]45\ and\ 45[/tex]** **show that all angles do not have different measure

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

**Step-by-step explanation:**

**Solving (1):**

[tex]n: n^3 > 0[/tex]

**Take **

[tex]n = -1[/tex]

[tex]-1^3 = -1[/tex]

[tex]n: n^3 > 0[/tex]* is not true for negative integers*

**Solving (2):**

**The angles of a right angled triangle are:**

[tex]45, 45\ and\ 90[/tex]

[tex]45\ and\ 45[/tex]** **show that all angles do not have different measure

**Solving (3):**

When

[tex]Bills = 48[/tex]

[tex]Counterfeit = 16[/tex]

The fraction is calculated as thus:

[tex]Fraction = \frac{Counterfeit}{Bills}[/tex]

[tex]Fraction = \frac{16}{48}[/tex]

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

Similarly, when

[tex]Bills = 39[/tex]

[tex]Counterfeit = 13[/tex]

[tex]Fraction = \frac{Counterfeit}{Bills}[/tex]

[tex]Fraction = \frac{13}{39}[/tex]

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

In order to test for the significance of a regression model involving 5 independent variables and 123 observations, the numerator and denominator degrees of freedom (respectively) for the critical value of F are

**Answer: ** The numerator and denominator degrees of freedom (respectively) for the critical value of F are 4 and 118 .

**Step-by-step explanation:**

We know that , for critical value of F, degrees of freedom for numerator = k-1

and for **denominator = n-k, where n= Total observations and k = number of independent variables.**

Here, Numbers of independent variables(k) = 5

Total observations (n)= 123

So, Degrees of freedom for numerator = 5-1=4

Degrees of freedom for denominator =123-5= 118

Hence,** the numerator and denominator degrees of freedom (respectively) for the critical value of F are ****4**** and**** 118 .**
