The aquarium has 198 guppies, angelfish and catfish altogether.
There are 4 times as many guppies as angelfish. There are 6 more
angelfish than catfish.
How many catfish are there?​

Answers

Answer 1

Answer:

Number of catfish = 28

Step-by-step explanation:

Let the number of catfish = c

Number of angle fish = c + 6

Number of guppies = 4*(c + 6) = 4c + 4*6 = 4c + 24

Total fishes = 198

c + c + 6 + 4c + 24 = 198           {Combine like terms}

c + c +4c + 6 + 24 = 198

                6c + 30 = 198              {Subtract 30 from both sides}

                     6c    = 198 - 30

                     6c   = 168

                       c = 168/6           {Divide both sides by 6}

                       c = 28

Answer:

-2.8 x 10^5 or -280,000

Step-by-step explanation:

We first have to look at:

P : Parenthesis

E : Exponents

M : Multiply

D : Divide

A : Add

S : Subtract

We have to solve the question in that order:

The first thing we do is figure out the value of the exponents from left to right since there are exponents inside the parenthesis.

10^4 is just 10x10x10x10 = 10,000

10^5 same thing 10x10x10x10x10 = 100,000

Now that we know the value of the exponents we can solve the equations inside the parenthesis:

12 x 10,000 = 120,000

(120,000) - ( 4 x 100,000)

4 x 100,000 = 400,000

So the final expression is:

(120,000) - (400,000) = -280,000

Factor 60x-12y
Plz help

Answers

Answer: 12(5x - y)

Step-by-step explanation:

60x - 12y can be factorized as 12(5x - y).

What is Factorization?

Factorization is the process of writing a number or expressions as a product of it's factors. In other words, it is the breaking down of a single number or expression into many using it's factors. When we multiply these factors altogether, we will get the original number.

Factorization can be done to numbers or expressions like polynomials and matrices as well.

We have two terms here, 60x and 12y.

Let us find the common factor of 60x and 12y.

12 is a common factor of both 60x and 12y.

60x = 12 × 5x and 12y = 12 × y

Taking 12 outside the bracket indicating as a common term,

60x - 12y = 12 (5x - y)

Hence, 60x - 12y is factorized as 12(5x - y).

The cross-section of a prism is in the shape of a trapezium as shown.​

Answers

Answer:

[tex]Length = 15cm[/tex]

Step-by-step explanation:

Given

The cross-section

[tex]Volume = 630cm^3[/tex]

Required

Calculate the length

We start by calculating the area of the trapezium cross-section.

[tex]Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height[/tex]

[tex]Area = \frac{1}{2}(9cm + 5cm) * 6cm[/tex]

[tex]Area = \frac{1}{2}* 14cm* 6cm[/tex]

[tex]Area = 42cm^2[/tex]

The length is then calculated from volume as:

[tex]Volume = Area * Length[/tex]

Substitute values for Volume and Area

[tex]630cm^3 = 42cm^2 * Length[/tex]

Make Length the subject

[tex]Length = \frac{630cm^3}{42cm^2}[/tex]

[tex]Length = 15cm[/tex]

Answer:

12 = 4

Step-by-step explanation:

Answer:

c ⋅ 4 = 12

Step-by-step explanation:

We know that on the right side of the hanger, it holds one square, and that square has a value of 12 units.

And on the left side, the hanger holds four pentagons, and each pentagon has a value of c.

So, we know that 4 pentagons equal one square, or 4c = 12.

So how can we make that into an equation?

To get 4c, we multiply c four times. It should look like this:

c ⋅ 4 = 4c

And, we know that 4c equals 12, so all we have to do is make an equation showing that. You should get:

c ⋅ 4 = 12

 *If you are looking for the value of c, you should get 3 because 3 ⋅ 4 = 12, proving c = 3

When Joseph moved into a new house, he planted two trees in his backyard. At the time of planting, Tree A was 16 inches tall and Tree B was 37 inches tall. Each year thereafter, Tree A grew by 6 inches per year and Tree B grew by 3 inches per year. Let AA represent the height of Tree A tt years after being planted and let BB represent the height of Tree B tt years after being planted. Write an equation for each situation, in terms of t,t, and determine the interval of time, t,t, when Tree A is taller than Tree B.

Answers

The tree A is 3t taller than tree B.

Equation to represent tree A = 16 + 6t

Equation to represent Tree B= 37+ 7t

What is linear equation?

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Given that : Tree A was 16 inches tall and Tree B was 37 inches tall.

Tree after 't' year

A= 16 + 6t

B = 37 + 7t

so,

A-B= 16 + 6t -(37+3t)

    = 16 + 6t - 37 -3t

    = 3t- 21

As tree A grew 2 times the tree B

then t'= 2t

A'- B'= 3t' -21

        = 3(2t)-21

        =6t -21

Thus, (A'- B')(A-B) = 6t-21- (3t-21)

                   = 6t-3t

                   = 3t

Hence the tree A is 3t taller than tree B

Equation to represent Tree A = 16 + 6t

                                     Tree B= 37+ 7t

The following sample data are from a normal population: 12 7 6 3 5 12 9 10 11 2 Calculate the point estimate of the population mean.

Answers

Answer:

The sample mean (x⁻ ) is the point of estimate of the Population mean

x⁻ = 7.7

The sample standard deviation   (S)  is the point of estimate of the Population standard deviation

 S = 3.65

Step-by-step explanation:

Step(i):-

Given data    12  7  6  3   5   12   9   10  11  2

Mean of the data

          [tex]x^{-} = \frac{12+7+6+3+5+12+9+10+11+2}{10} = 7.7[/tex]

x          :     12      7       6       3        5         12      9       10           11        2

x-x⁻      :   4.3     -0.7    -1.7   -4.7    -2.7     4.3    1.3      2.3         3.3     -5.7

(x-x⁻  )² :  18.49  0.49   2.89  22.09 7.29  18.49 1.69    5.29  10.89   32.49

Step(ii):-

Standard deviation of the sample

[tex]S^{2} = \frac{sum (x-x^{-})^{2} }{n-1} = \frac{120.1}{10-1} = 13.344[/tex]

Standard deviation of the sample

 S = √13.344 =3.65

Final answer:-

The sample mean (x⁻ ) is the point of estimate of the Population mean

x⁻ = 7.7

The sample standard deviation   (S)  is the point of estimate of the Population standard deviation

 S = 3.65

Mya bought 6 slices of bread for $2.40 at her local grocery
store. How much would a package with 10 slices cost at the price
per slice?

Answers

Answer:

$4.00

Step-by-step explanation:

Find how much it would cost for one slice of bread by dividing 2.40 by 6 to get .4.

So .40 cents is for 1 slice of bread. If you got 10 slices of bread (multiply 10 by .4) you would get 4.

So it costs 4 dollars for 10 slices of bread.

carol used 1 1/4 cups of flour in 2 muffins How many cups of flour are needed to make 12 similar muffin

Answers

Answer:

B

Step-by-step explanation:

Hey there! first, we divide 1 1/4 by 2 to get how much flour is used to make one muffin then we multiply 0.625by 12  because 1 1/4  ÷ 2 = 0.625

12 × 0.625 = 7.5            

  (7.5 is equivalent to 7 1/2)

Carol need  7[tex]\frac{1}{2}[/tex] cups of flour for 12 muffins.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Carol used 1[tex]\frac{1}{4}[/tex] cups of flour in 2 muffins.

That means, Carol used 5/4 cups of flour in 2 muffins.

Unit rate = 2x4/5

              = 8/5

When we have 12 muffins,

then flour = 12x 5/8

                = 60/8

                = 7[tex]\frac{1}{2}[/tex] cups of flour.

Therefore, 7[tex]\frac{1}{2}[/tex] cups of flour for 12 muffins.
