The value of z in the given inverse variation is,  z= 1 / 9

The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity.

In the question given,

first of all find the value of K in the model by putting in the values of x, y, and z so that to find the function model.

z = k / (x) (y)

0.5 = k / (2) (4)

k = 4

now write the function equation again by putting value of k,

⇒ z = 4 / (x) (y)

put x = 4 and y = 9 to find the value of z.

z = 4 / 36

z = 1 /9

Thus, z = 1/9

Step-by-step explanation:

5 digit number

5abcd

a = 2 or a = 3. but a = 3 means the upper limit of 53,000. and the sum of digits is 8 and not 21.

so, a = 2.

d = 3n

c = b

5 + a + b + c + d = 21

5 + a + 2b + 3n = 21

a + 2b + 3n = 16

2 + 2b + 3n = 16

2b + 3n = 14

so, n must be an even number to allow an even result (14). therefore, n = 0 or n = 2 (any larger even number n like 4 would not create a single digit result)

if n = 0, then 2b = 14, b = 7

if n = 2, then 2b + 6 = 14, 2b = 8, b = 4

so, we have the options

The amount invested in the bond with 5% simple interest is $16,666.67

The amount invested in the bond with 6.5% simple interest is $33,333.33  

What is simple interest?

The interest earned under a simple interest arrangement is determined as the amount invested multiplied by the interest rate and the time the investment lasts

I=PRT

let us assume that x was invested in the bond with 5%

interest on x=5%*x=0.05x

amount invested in other bond=50000-x

interest earned on 6.5%=(50000-x)*6.5%

interest earned on 6.5%=3250-0.065x

total interest=0.05x+3250-0.065x

total interest=3250-0.015x

total interest=3000

3000=3250-0.015x

0.015x=3250-3000

0.015x=250

x=250/0.015

1: 500,000 cm

500,000cm can also be written as 5000m or 5 km

So it becomes 1:5km

the 1 represents 1cm on the map so every centimeter in the map is 5 kilometers in real life

If we want to get what 7 cm would be in kilometers then we have to multiply both sides by 7.

So it would be 1 x 7 and 5x 7

it would end up being 7 : 35 km

The answer is: 35km

The distance between two points (2,-2) and (-3,-1) is √26 units.

Given points are (2,-2) and (-3,-1)

Let A(2,-2), B(-3,-1)

We need to calculate the distance between two points.

We know that distance between two points means the length of the line segment that connects two points in the 2D plane.

The formula for finding the distance between the two points A(x₁, y₁),

B(x₂, y₂) in a plane is given by

                                D = √((x₂ - x₁)² + (y₂ - y₁)²)

Now we have two points A(2,-2), B(-3,-1)

By using the above formula we get the distance as

D = √((-3 - 2)² + (-1 - (-2))²)

D = √((-5)² + (-1+2)²)

D = √(25 + (1)²

D = √(25+1)

D = √26 units

The time taken to reach $14200 in the bank with 4.25% interest compounded is 50 years

The time taken to reach 14200 with interest compounded semi-annually can be calculated by

[tex]A = P (1 +\frac{R}{100n})^{nT}[/tex]

where A is the total amount at the end of the period

          P is the principal amount

          R is the rate of interest

          n is the no. of interest compounded per year

          T is the time period

We know that A = 14200

                       P = 9000

                       R = 4.25%

                       n = 2

By substituting these values, we get

                    14200 = 9000 [1 + (4.25 /200[tex]]^{2T}[/tex]

                    14200/9000 =  [tex](1+0.02125)^{2T}[/tex]

                              1.5778 =  [tex](1+0.02125)^{2T}[/tex]

                          1.5778 =  [tex](1+0.02125)^{2T}[/tex]

                           1.5778  =[tex](1 +0.02125)^{2T}[/tex]

Taking logs on both sides,

                    log (1.5778) = log [tex](1+0.02125)^{2T}[/tex]

                    log (1.5778) = 2T log(1 +0.02125)

                              0.198 = 2T log(1.02125)

                             0.198 = 2T (0.00913)

                             0.918 = 0.01826 T

                                    T = 0.918 / 0.01826

                                    T = 50.27 yrs

The rate at which Riya is applying mulch in m³/m² is 0.25m³/m²

From the question, we are to determine the rate at which Riya is applying mulch in m³/m²

From the given information, we have that

Riya is applying mulch to her garden at a rate of 250,000 cm³ of mulch for every m² of the garden space

That is,

The rate at which she is applying mulch is 250,000 cm³/m²

Now, to determine the rate in m³/m², we will convert 250,000 cm³ to m³

Converting 250,000 cm³ to m³

250,000 cm³  = 250000 × (10⁻²)³ m³

= 250000 × 10⁻⁶ m³

The measure of ∠B is 60°

The measure of ∠H is 135°

The length of AB is 2cm

From the question, we are to determine the measure of the angles and the length of line AB.

From the given information, we have that

Quad ABCD. is similar to Quad, EFGH

In the diagram,

Measure of ∠F = 60°

But, ∠B ≅ ∠F

∴ The measure of ∠B = 60°

Measure of ∠H

∠E + ∠F + ∠G + ∠H = 360° (Sum of angles in a quadrilateral)

From the diagram,

m ∠E = 90°

m ∠F = 60°

∠G ≅ ∠C

m ∠C = 75°

∴ m ∠G = 75°

Thus,

90° + 60° + 75° + ∠H = 360°

225° + ∠H = 360°

∠H = 360° - 225°

∠H = 135°

Hence, the measure of ∠H is 135°

Length of AB

The length of HE is twice the length of DA,

Thus,
