Answer:

here is the ratio  1 : 1.25   (sharks: dolphins)

Step-by-step explanation:

The ratio of sharks to dolphins is 4 : 5

Suppose the  real measurements were "a" and "b"

This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.

Thus, a = px, b = qx

Given Number of sharks = 4

Number of dolphins = 5

Therefore, the ratio of sharks to dolphins

= 4 : 5

Or  1 : 1.25

Number of animals = number of sharks + number of dolphins

Number of animals = 4 + 5 = 9

Answer:

Substitute x = -9 and x = -3 into  \(y=5-\dfrac13x\)  

\(\implies y=5-\dfrac13(-9)=8\)

\(\implies y=5-\dfrac13(-3)=6\)

Plot a closed circle at (-9, 8) and and open circle at (-3, 6).

Connect the points with a line segment.

Substitute x = -3 and x = 8 into \(y=\dfrac23x\)

\(\implies y=\dfrac23(-3)=-2\)

\(y=\dfrac23(8)=\dfrac{16}{3}\)

Plot closed circles at (-3, 2) and (8, 16/3).

Connect the points with a line segment.

The volume of the closet space = 207,936 in³

The volume of the one roll of toilet paper = 141.3in³

To calculate the volume of the closet, the formula that should be used is the formula for the volume of a rectangle = length×width×height.

Where;

length = 57 in

width = 57

height = 64

volume = 57×57×64 = 207,936 in³

The slope of the tangent line is:

a = (df(x1)/dx)

The slope of the normal one is:

a' = -1/(df(x1)/dx)

For any function y = f(x), we define the slope of the tangent line at the point x as the derivative evaluated in x.

So if we want to find the slope of the tangent line at the point (x1, y1), we just need to differentiate and evaluate in x1, then the slope will be given by:

df(x1)/dx

And the normal slope is the slope of the perpendicular line, two slopes are perpendicular if the product is -1, then:

a*(df(x1)/dx) = -1

a = -1/(df(x1)/dx)

Where df/dx reffers to the derivative of f(x).

To write the ratio of 2/3 to 8 as a fraction in simplest form, we need to divide the numerator and denominator by their greatest common factor (GCF).The GCF of 2 and 8 is 2.So, we divide both the numerator and denominator by 2:2/3 ÷ 8/1 = (2/3) ÷ (8/1) = 2/3 x 1/8 = (2 x 1) / (3 x 8) = 2/24Now, we can simplify the fraction by dividing the numerator and denominator by their greatest common factor again.The GCF of 2 and 24 is 2.So, we divide both the numerator and denominator by 2:2/24 ÷ 2/2 = (2/24) ÷ (2/2) = 2/24 x 1/2 = (2 x 1) / (24 x 2) = 1/12Therefore, the ratio of 2/3 to 8 as a fraction in simplest form is 1/12.

Answer:

How to find Ratio?

Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B. For example, if A is five and B is 10, your ratio will be 5/10

In order to find the ratio of a certain number to another number or the relation of each other, we also need to know the concept of fraction and percentage.

1/12 or 1 to 12

The ratio is 2/3*8=23⋅8=2/24=1/12

Answer:

if q is odd

Step-by-step explanation:

Hello,

Either q is odd or is even.

Case 1 - we can find k integer so that q = 2k

Then, in the case

\(q^2-1=4k^2-1\)

This is not divisible by 8, for instance, q = 6

\(q^2-1=36-1=35=7*5\)

Case 2 - we can find k integer so that q = 2k+1

\(q^2-1=(2k+1)^2-1=4k^2+4k+1-1=4k(k+1)\)

k(k+1) is divisible by 2 so the initial number is divisible by 8

Conclusion, the answer is q is odd.

Step-by-step explanation:

The expression for the perimeter is P = 12x - 16

The given parameters are

Length = 3x + 1

Width = 3x - 9

The perimeter is calculated as

P = 2 * (Width + Length)

So, we have

P = 2 * (3x + 1 + 3x - 9)

Evaluate

P = 2* (6x - 8)

Expand

P = 12x - 16

Hence, the expression for the perimeter is P = 12x - 16

Answer:

B. By personal experimentation and testing

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

10x - 20 + 6x + 8 = 180

Supplementary angles

Answer:

x = 12

Step-by-step explanation:

The two given angles create a straight line (Definition of Straight Line). This means that:

\((10x - 20) + (6x + 8) = 180\)

First, combine like terms. Like terms are terms that share the same amount of the same variables:

\((10x + 6x) + (8 - 20) = 180\\(16x) + (-12) = 180\\16x - 12 = 180\\\)

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

~

First, add 12 to both sides of the equation:

\(16x - 12 = 180\\16x - 12 (+12) = 180 (+12)\\16x = 180 + 12\\16x = 192\)

Next, divide 16 from both sides of the equation:

\(\frac{16x}{16} = \frac{192}{16} \\x = \frac{192}{16}\\ x = 12\)

12 is your answer.

Answer:

There is enough paint to cover the tank with one layer of paint.

Step-by-step explanation:

Given the cilindrical configuration of the tank and supposing that only external face must be painted, the surface area of the section (lateral wall + lid) can be calculated by the following expression:

\(A_{s} = 2\pi\cdot r\cdot h + \pi\cdot r^{2}\)

Where \(r\) and \(h\) represent the radius and the height of the cube, respectively.

If \(r = 0.55\,m\) (a diameter is two times the length of radius) and \(h = 1.4\,m\), the intended surface area is:

\(A_{s} = 2\pi\cdot (0.55\,m)\cdot (1.1\,m)+\pi\cdot (0.55\,m)^{2}\)

\(A_{s} \approx 4.751\,m^{2}\)

It is known that 250 mL of paint are needed to cover a square meter of the surface area, the needed amount of paint to cover the required area is estimated by simple rule of three:

\(Q = \frac{4.751\,m^{2}}{1\,m^{2}}\times (250\,mL)\)

\(Q = 1187.75\,mL\,(1.188\,L)\)

In consequence, there is enough paint to cover the tank with one layer of paint.

Step-by-step explanation:

1. To solve, first wrote it into an equation. Also, the letter x will stand for the unknown number.

4 + 7 = 11

11 + x = 16

2. Isolate the varable by subtracting 11 from both sides of the equation.

11 + x = 16

- 11 - 11

x = 5
