Answer:

8 guppies

Step-by-step explanation:

Let:

x = number of goldfishes

y = number of guppies

We can come up with two equations:

x + y = 26

3x +4y = 86

We use the first equation to come up with a solution for one of the unknowns:

x = 26 - y

We can use this to substitute the x on the second equation:

[tex]3x + 4y = 86\\\\3(26-y) + 4y=86\\\\78 - 3y + 4y = 86\\\\78 + y = 86\\\\y = 86 - 78\\\\y = 8[/tex]

So she bought 8 guppies.

The total guppies Samantha buys are 8 and the total goldfish she buys are 18 and this can be determined by forming the linear equation.

Given :

Let the total number of goldfish be 'x' and the total number of guppies be 'y'. Then the linear equation that represents the total number of fish is given by:

x + y = 26  

x = 26 - y   ---- (1)

The linear equation that represents the total spent $86 is given by:

3x + 4y = 86    --- (2)

Now, substitute the value of 'x' in equation (2).

3(26 - y) + 4y = 86

Simplify the above equation.

78 - 3y + 4y = 86

y = 86 - 78

y = 8

Now, substitute the value of 'y' in equation (1).

x = 26 - 8

x = 18

So, Samantha buys 8 guppies.

Answer:

>,<,<,>,<

Step-by-step explanation:

The bigger side in the >/< Symbols mean that value is larger

First put your numbers in order from least to greatest (These are negative numbers so that means that the smallest number is the one farthest away from zero)

-49, -43, -39, -18, -14, -12, -9

Mean is adding all the numbers together and dividing the sum by how many numbers there are in the data set

-49 + (-43) + (-39) + (-18) + (-14) + (-12) + (-9) = -184

There are seven numbers so divide -184 by 7:

-184 ÷ 7 ≈ 26.29

Median is the number in the middle. Take away the smallest number and the biggest number on each layer until you get to the middle

-49, -43, -39, -18, -14, -12, -9

       -43, -39, -18, -14, -12

              -39, -18, -14

                      -18 <-------------------Median

Mode is whatever number appears the most often in the data. In this case all the numbers appear only once so there is no mode

Range is subtracting the largest number by the smallest number

-9 - (-49) = 40

2. Data in order

13, 13, 13, 15, 21, 23, 25, 37

Outlier is the number that is a number that is rather far from the other number in the data

a. In this case the outlier is 37

b. 13 + 13 + 13 + 15 + 21 + 23 + 25 + 37 = 160

160 ÷ 8 = 20

c. 13 + 13 + 13 + 15 + 21 + 23 + 25  = 123

123 ÷ 7 = 17.57

Hope this helped!

Answer:

(1, 3)

Step-by-step explanation:

If the translation is ...

(3, 2) + (a, b) = (4, 5)

Then we can find (a, b) by subtraction:

(4, 5) -(3, 2) = (a, b) = (4-3, 5-2) = (1, 3)

Not the image of point (0, 0) will be ...

(0, 0) + (a, b) = image

(0, 0) + (1, 3) = (0+1, 0+3) = (1, 3)

The image of the point is (1, 3).

Answer:

C. 7  1/2 pounds; 120 ounces

Step-by-step explanation:

I'll assume you wanted to write each loaf weighs 1 and 1/4 (1.25) pounds  and not 114 pounds... since that makes sense considering the choices for answer.

So, to get the total weight of the 6 loafs, we multiply by 6 the weight of one...

TP = 6 * 1.25 = 7.5 or 7 1/2 pounds

To get that in ounces, we just have to remember there are 16 ounces per pound... so

TO = 7.5 lbs * 16 ounces/lbs = 120 ounces

B is correct. I’ve noticed that you’ve posted a lot of questions like this, so here’s how I remember it. Soh-Cah-Toa

Soh stands for Sin=Opposite (the side opposite to the angle) over hypotenuse (the side opposite to the right angle)

Cah stands for Cos=Adjecent (the side next to the angle that is not the hypotenuse) over the hypotenuse

Toa stands for Tan=opposite over adjacent

Good luck! Hope I helped you understand.

Answer:

Step-by-step explanation:

A situation in which doubling time is constant is a situation that can be modeled by an exponential function. Here, you're given an exponential function, though you're not told what the variables mean. That function is ...

[tex]P(t)=P_0(2^{t/d})[/tex]

In this context, P0 is the initial salary, t is years, and d is the doubling time in years. The function gives P(t), the salary after t years. In this problem, the value of t we're concerned with is the difference between age 22 and age 65, that is, 43 years.

In Collin's case, we have ...

P0 = 55,000, t = 43, d = 15

so his salary at retirement is ...

P(43) = $55,000(2^(43/15)) ≈ $401,157.89

In Cameron's case, we have ...

P0 = 35,000, t = 43, d = 10

so his salary at retirement is ...

P(43) = $35,000(2^(43/10)) ≈ $689,440.87

___

Sometimes we like to see these equations in a form with "e" as the base of the exponential. That form is ...

[tex]P(t)=P_{0}e^{kt}[/tex]

If we compare this equation to the one above, we find the growth factors to be ...

2^(t/d) = e^(kt)

Factoring out the exponent of t, we find ...

(2^(1/d))^t = (e^k)^t

That is, ...

2^(1/d) = e^k . . . . . match the bases of the exponential terms

(1/d)ln(2) = k . . . . . take the natural log of both sides

So, in Collin's case, the equation for his salary growth is

k = ln(2)/15 ≈ 0.046210

P(t) = 55,000e^(0.046210t)

and in Cameron's case, ...

k = ln(2)/10 ≈ 0.069315

P(t) = 35,000e^(0.069315t)

Answer:

Step-by-step explanation:

You find out how much the sale price is by subtracting 25% of 40 from 40:

40 - [(.25)(40)] and that equals 30.  So the sale price is $30.  Now if the tax is 10% (.1 in decimal form), we find the total cost by adding .1(30) to 30:

30 + [(.1)(30)] which is $33

Answer:

  b ≈ 3.1

Step-by-step explanation:

The law of sines tells you ...

  b/sin(B) = c/sin(C)

Here, you have to find angle C based on the sum of the angles of a triangle being 180°.

 C = 180° - A - B = 180° - 69° - 32° = 79°

Multiplying the above law of sines equation by sin(B), you have ...

  b = c·sin(B)/sinc(C) = 5.7·sin(32°)/sin(79°) ≈ 3.07707

  b ≈ 3.1 . . . . . rounded to tenths

Answer:

[tex]\displaystyle 3,1 ≈ b[/tex]

Step-by-step explanation:

First, find [tex]\displaystyle m∠C,[/tex]accourding to the Triangle-Sum Theorem:

[tex]\displaystyle 180° = 32° + 69° + m∠C \hookrightarrow 180° = 101° + m∠C; 79 = m∠C[/tex]

Now that we have all three angles, we can solve for edge b

[the second edge], using the Law of Sines:

[tex]\displaystyle \frac{c}{sin∠C} = \frac{b}{sin∠B} = \frac{a}{sin∠A} \\ \\ \frac{5,7}{sin\:79°} = \frac{b}{sin\:32°} \hookrightarrow 3,0770743283... = \frac{5,7sin\:32°}{sin\:79°} \\ \\ 3,1 ≈ b[/tex]

Answer:

The perimeter of the triangle is 56 cm.

Step-by-step explanation:

Given:

The length of the hypotenuse is 24 cm

Radius of the circle r=4 cm

To Find:

The perimeter of the triangle=?

Solution:

Let us see the below diagram representing situation.  

Here, first we have drawn the radius of circle perpendicular to the sides of triangle,

We have Taken PB = 4 because, it is a side of square formed there, and we take OC as x.

Then, QC also becomes x as they are tangents from single point, so they are equal.

Now, AQ becomes 24 – x as AC is 24 according to given information.

So, perimeter = AB + BC + CA  

Perimeter = (24 – x + 4) + (4 + x) + (24 – x + x)

Perimeter = 28 – x + 4 + x + 24  

Perimeter = 28 + 28 = 56

Hence, the perimeter of the triangle is 56 cm.

ANSWER

[tex]16\pi \: sq.in[/tex]

EXPLANATION

The area of a sector is calculated using the formula,

[tex]Area = \frac{arc \: measure}{360 \degree} \times \pi {r}^{2} [/tex]

The arc measure is given as 45°

The radius of the circle is 8 inches.

We substitute to obtain,

[tex]Area = \frac{45 \degree}{360 \degree} \times \pi \times {8}^{2} [/tex]

[tex]Area = \frac{1}{4} \times 64\pi = 16\pi[/tex]

The answer is:

The correct option is the second option:

[tex]SectorArea=8\pi in^{2}[/tex]

To answer the question, we need to calculate the total area of the circle (which corresponds to 360°) and then, calculate the equivalent area to the sector of the arc that measures 45°

Calculating the total area, we have:

[tex]TotalArea=\pi radius^{2} \\\\TotalArea=\pi 8^{2} =64\pi in^{2}[/tex]

Now, we need to consider that the calculated area (total area) correspondes to all 360° that conforms the interior angle of a circle, now, if we want to calculate the area that represents a sector of the arc that measures 45°, we have to use the following formula:

[tex]SectorArea=\frac{360\°}{45\° }*TotalArea\\\\SectorArea=\frac{45\°}{360\° }*64\pi in^{2}=\frac{1}{8} *64\pi in^{2}\\\\SectorArea=8\pi in^{2}[/tex]

Hence, we have that the correct option is the second option:

[tex]SectorArea=8\pi in^{2}[/tex]

To solve the equation cos(2θ) + sin^2(θ) = 0 using a double- or half-angle formula, rewrite the equation and combine like terms to simplify.

To solve the equation cos(2θ) + sin^2(θ) = 0 using a double- or half-angle formula, we can rewrite the equation as:

2cos^2(θ) - 1 + sin^2(θ) = 0

Using the identity sin^2(θ) = 1 - cos^2(θ), we can substitute and simplify:

2cos^2(θ) - 1 + (1 - cos^2(θ)) = 0

Combining like terms, we have:

-cos^2(θ) + cos^2(θ) = 0

This simplifies to:

0 = 0

Since 0 = 0 is a true statement, the equation is satisfied for all values of θ within the interval [0, 2π).

The average rate of change is the change in attendance over change in time.

Δy / Δx

(333.7 - 298.3) / (5 - 2)

11.8

So the average rate of change is an increase of 11.8 thousand people per year.

The average rate of change from Year 2 to Year 5 is 11.8 if at year 2 the attendance is 298.3 and at year 5 the attendance is 333.7

It is defined as the change in values of a dependent variable with respect to the independent variables.

We have to find the average rate of change from Year 2 to Year 5:

At year 2 the attendance = 298.3

At year 5 the attendance = 333.7

Average rate of change = (333.7-298.3)/(5-2)

= 11.8

Thus, the average rate of change from Year 2 to Year 5 is 11.8 if at year 2 the attendance is 298.3 and at year 5 the attendance is 333.7
