Answer:

A. x is ⅓ of y

Step-by-step explanation:

x : y

= 1 : 3

Therefore,

x = 1

y = 3

If so x is 1/3 of y

Answer:

3

Step-by-step explanation:

x x6=18

x=3

Answer:

(18=6 times x)  you would divide both sides by 6 since inverse operations and to leave the x by itself. 18/6 is 3 so 3=x

Answer:

1250 m²

Step-by-step explanation:

Let x and y denote the sides of the rectangular research plot.

Thus, area is;

A = xy

Now, we are told that end of the plot already has an erected wall. This means we are left with 3 sides to work with.

Thus, if y is the erected wall, and we are using 100m wire for the remaining sides, it means;

2x + y = 100

Thus, y = 100 - 2x

Since A = xy

We have; A = x(100 - 2x)

A = 100x - 2x²

At maximum area, dA/dx = 0.thus;

dA/dx = 100 - 4x

-4x + 100 = 0

4x = 100

x = 100/4

x = 25

Let's confirm if it is maximum from d²A/dx²

d²A/dx² = -4. This is less than 0 and thus it's maximum.

Let's plug in 25 for x in the area equation;

A_max = 25(100 - 2(25))

A_max = 1250 m²

2 inches : 8 feet

simplified scale:

1 inch : 4 feet

Answer:

3i

Step-by-step explanation:

3i x 3i = -9

-3i x -3i = -9

Therefore the square root of -9 is 3i or -3i

The simplified radical expression ±√(-9) is ±3i

The expression ±√(-9) involves finding the square root of a negative number. In the real number system, this is not possible, as no real number multiplied by itself will result in a negative value. To overcome this limitation, mathematicians introduced the concept of imaginary numbers. The imaginary unit, denoted by 'i,' is defined as √(-1).

Now, let's simplify the expression ±√(-9) step by step:

Step 1: Begin by recognizing that √(-9) is the square root of -9.

Step 2: Since √(-1) is 'i,' we can rewrite √(-9) as √(9) * √(-1).

Step 3: The square root of 9 (√9) is 3.

Step 4: Replace √(-1) with 'i.'

Step 5: The final result is 3i.

Therefore, the simplified form of ±√(-9) is ±3i.

Answer:

a. 76 cm

b. 16 in.

c. 225 cm

Step-by-step explanation:

a. Converting 30 inches to centimetres:

When y(inches) = 30, x (centimetres) = 76

So, 30 in. = 76 cm

b. When x (cm) = 40, y (in.) = 16

So, 40 cm = 16 in.

c. Given that a fence is 7 ft 6 in. high, and 1 ft = 12 in., to find the height of the fence in cm, first convert the height to in.

Convert 7ft to inches:

If 1 ft = 12 in., then,

7 ft = 7*12 = 84 inches

The height of the fence in inches = 84 + 6 = 90 inches

Using the graph, find the unit rate using any point on the line, say (100, 40):

Unit rate = y/x = inches/centimeters =

Unit rate (m) = 40/100 = ⅖

Write an equation for the line:

To do this, substitute m = ⅖ into y = mx

Equation: y = ⅖x

Let's convert the height of the fence, 90 inches, to centimetres:

To convert to cm, substitute y = 90 into y = ⅖x

Thus:

90 = ⅖*x

5*90 = 2x

450 = 2x

Divide both sides by 2

450/2 = x

225 = x

Height of the fence in cm = 225 cm

Step-by-step explanation:

Answer:

Radius, r = 26.57 cm and diameter = 53.14 cm

Step-by-step explanation:

Given that,

The circumference of a coin, C = 167 cm

We need to find the radius and the diameter of the coin.

The formula for the circumference of a circle is given by :

[tex]C=2\pi r[/tex]

Where

r is radius of coin

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{167}{2\pi}\\\\r=26.57\ cm[/tex]

Diameter, d = 2r

d = 2(26.57) cm

= 53.14 cm

Hence, this is the required solution.

Answer:

Claire has 16 stamps

Step-by-step explanation:

Proportions

If two variables are proportional, their ratio is constant. For example, the distance traveled by car is proportional to the time it travels at a constant speed. We write it as d:t=constant.

It's known the number of Claire's stamps to the number of John's stamps is 2:3 and John has 24 stamps.

This means the following relation must stand:

[tex]\displaystyle \frac{C}{J}=\frac{2}{3}[/tex]

Where C is the number of stamps of Claire and J is the number of stamps of John. We know J=24, thus:

[tex]\displaystyle \frac{C}{24}=\frac{2}{3}[/tex]

Solving for C:

[tex]\displaystyle C=24\cdot\frac{2}{3}[/tex]

C = 16

Answer:

x = 5.943

Step-by-step explanation:

Reference angle = 23°

Side opposite to reference angle = x

Adjacent side = 14

Therefore, we would apply TOA to find x.

Thus:

tan (23) = x/14

Multiply both sides by 14

14 × tan(23) = x

5.94264742 = x

x = 5.943 (to 3 decimal places)

Answer:

18/5

Step-by-step explanation:

To find the improper fraction change the whole number into a fraction:

3 *5/5 = 15/5 which is the same as 3

then add the remaining 3/5 to the fraction

15/5 + 3/5

Answer:

[tex]\frac{dr}{dh} =-\frac{r}{2h}[/tex]

Step-by-step explanation:

The volume of a cylinder is given by the formula:

V = πr²h,

Where V is the volume, r is the radius of the cylinder and h is the height of the cylinder.

We are to express the rate of change of the radius of the clay with respect to the height of the clay in terms of height h and radius r.

That means we express dr / dh in terms of height h and radius r. To do this, we have to first differentiate the volume with respect to the height, i.e. find dV / dh:

V = πr²h

[tex]\frac{dV}{dh}= \frac{d}{dh} (\pi r^2h)\\\\\frac{dV}{dh}= \pi r^2 + 2\pi rh \frac{dr}{dh} \\\\The\ volume\ is\ constant\ hence\ \frac{dV}{dh}=0.\ We\ get\ that:\\\\0= \pi r^2 + 2\pi rh \frac{dr}{dh}\\\\- \pi r^2 =2\pi rh \frac{dr}{dh}\\\\ \frac{dr}{dh}=-\frac{\pi r^2}{2\pi rh}\\\\ \frac{dr}{dh}=-\frac{r}{2h}[/tex]:

The given expression is 14x²+21x

Fourteen x square plus twenty one times of x.

x is the variable and plus is the operator.

14x²+21x

We need to take 7x as common from two terms.

When the quadratic expression is a product of two factors where each one is a linear expression, this is called the factored form.

Seven x is product of two times of x plus three.
