Write two number so that the value of the digit 9 in the second number is 10 times the value of digit 9 in the first number ?

Answers

Answer 1

That’s easy it’s 18 because the 9x9=18 and there’s a 10s digit

Answer 2

The two numbers with the value of 9 in the first digit being 10 times the value of 9 in the second digit are 98 and 9.

Given that the value of the digit 9 in the second number is 10 times the value of digit 9 in the first number .

The first number will be 9 and the second number will be 98.

In the second number, the 9 is in the tens position which means that it has the value of 90.

In the first number, the value of 9 is simply 9.

90 is 10 times the value of 9 which means that 9 and 98 satisfy the requirements.

The first number will be 9 and the second number will be 98.

The rearranged formula for volume in terms of radius,r is [tex]\sqrt[3]{\frac{V}{\pi } }[/tex].

What is volume?

Volume is a measure of enthralled three-dimensional space.It's frequently quantified numerically using SI-deduced units or by colorful Homeric units( similar to the gallon, quart, boxy inch). The description of length( cubed) is interrelated with volume. The volume of a vessel is generally understood to be the capacity of the vessel; i.e., the quantum of fluid( gas or liquid) that the vessel could hold, rather than the quantum of space the vessel itself displaces.In ancient times, volume is measured using analogous-structured natural holders and latterly on, standardized holders. Some simple three-dimensional shapes can have their volume fluently calculated using computation formulas. Volumes of more complicated shapes can be calculated with integral math if a formula exists for the shape's boundary.

Volume, V = [tex]\pi r^3[/tex]

Rearranging,

r =[tex]\sqrt[3]{\frac{V}{\pi } }[/tex]

Suppose that the ratio of males to females in the sales field of a large company is 4:5. if there
are 81 sales representatives in the company, how many are male and how many are female?

Answers

There are 36 males and 45 females in the sales field.

Ratio of the number:

Ratios compare two numbers, usually by dividing them.

For example,

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.

Given.

Suppose that the ratio of males to females in the sales field of a large company is 4:5.

Total number of representatives = 81.

Now, we need to find the number of males and number of females.

Let x be the number of representatives.

So, based on the ratio we have written this as,

=> 4x : 5x = 81

So, the total number of representatives is,

=> 4x + 5x = 81

=> 9x = 81

=> x = 81/9

=> x = 9

So, the number of males is

=> 4x => 4(9) = 36

And the number of females is,

=> 5x => 5(9) = 45

Therefore, there are 36 males and 45 females in the sales field.

Complete the standard form equation representing the quadratic relationship displayed above, where a,b, and c are consonants.

Answers

Answer:

y = - 2x² + 8x + 5

Step-by-step explanation:

the equation of a quadratic function in standard form is

y = ax² + bx + c ( a ≠ 0 )

to find a, b and c use ordered pairs from the table

(0, 5 )

5 = a(0)² + b(0) + c = 0 + 0 + c = 5 ⇒ c = 5 , then

y = ax² + bx + 5

(1, 11 )

11 = a(1)² + b(1) + 5 = a + b + 5 ( subtract 5 from both sides )

a + b = 6 → (1)

(2, 13 )

13 = a(2)² + b(2) + 5 = 4a + 2b + 5 ( subtract 5 from both sides )

4a + 2b = 8 → (2)

solve the 2 equations simultaneously to find a and b

multiplying (1) by - 2 and adding to (2) will eliminate b

- 2a - 2b = - 12 → (3)

add (2) and (3) term by term to eliminate b

2a + 0 = - 4

2a = - 4 ( divide both sides by 2 )

a = - 2

substitute a = - 2 into (1) and solve for b

- 2 + b = 6 ( add 2 to both sides )

b = 8

then a = - 2, b = 8 and c = 5 gives the standard quadratic function

y = - 2x² + 8x + 5

Step-by-step explanation:

standard equation would be

y = ax² + bx + c

out of that we know already from (0, 5) that c = 5, as

a×0² + b×0 + c = 5.

because of (-1, -5) we see

-5 = a×1 + b×-1 + 5 = a - b + 5

-10 = a - b

a = b - 10

because of (1, 11) we see

11 = a×1 + b×1 + 5 = a + b + 5

6 = a + b

now we use the previous equation :

6 = (b - 10) + b = 2b - 10

16 = 2b

b = 8

a = b - 10 = 8 - 10 = -2

so, our standard equation is

y = -2x² + 8x + 5

Answers

Answer:

Both sentences are false.

Step-by-step explanation:

Let's solve for x:

2x + 4y - 31 = 123

2x = 123 - 4y + 31

2x = 154 - 4y

x = 77 - 2y

The product of two number is -100. One of the factor is less than 10 and more than 0

Answers

The given problem has 4 different solutions as below.

(1, -100)(2, -50)(4, -25)(5, -20)

Given that the product of the two numbers is -100.

And one of the factors is less than 10 and more than 0.

Assume c and d are the two required numbers.

Then we have cd = -100, here 0 < c <10.

We know that the factors of 100, which are less than 10 and greater than 0 are 1, 2, 4, and 5.

When c = 1, we get 1 x d = -100 ⇒ d = -100

When c = 2, we get 2 x d = -100 ⇒ d = -100/2 = -50

When c = 4, we get 4 x d = -100 ⇒ d = -100/4 = -25

When c = 5, we get 5 x d = -100 ⇒ d = -100/5 = -20

So, the other factors corresponding to the above factors are -100, -50, -25, and -20.

Therefore, the given problem has 4 different solutions as below.

identify the graph of the ellipse.
[tex]\frac{(x-3)^{2} }{16} +\frac{y-4^{2} }{9} =1[/tex]

Answers

The correct graph of the ellipse is identified and attached below.

Given the equation is (x₋3)²/16 ₊ (y₋4)²/9 = 1

step 1: identify the center (h,k) of the ellipse in standard form:

(x₋h)²/a² ₊ (y₋k)²/b² = 1

In the standard form of an ellipse, notice that there is a minus sign in front of the h and k.

In our equation (x₋3)²/16 ₊ (y₋4)²/9 = 1 , we have:

h = 3 and k = 4

Therefore, center (h,k) = (3,4)

Step 2: Identify the orientation by determining the major axis and minor axis in (x₋h)²/a² ₊ (y₋k)²/b² = 1

if a>b, the major axis is horizontal and the minor axis is vertical, making the ellipse a horizontal ellipse.

if a<b, the minor axis is horizontal and the major axis is vertical, making the ellipse a vertical ellipse.

For (x₋3)²/16 ₊ (y₋4)²/9 = 1

a² = 16, a = 4 and b² = 9 , b = 3

so, 4>3, the major axis is horizontal and the minor axis is vertical, making the ellipse a horizontal ellipse.

Step 3:

Plot the co-vertices along the minor axis and the vertices along the main axis (endpoints). No matter which way around, draw points a horizontal distance of a to the left and right from the center and points b above and below the center.

Therefore the vertices are marked along the major axis.

vertices are (3,7) and (3,1)

and co vertices are marked along the minor axis

co vertices are (₋1,4 ) and (7,4)

step 4: connect the vertices and co vertices making a smooth horizontal ellipse.

Hence a horizontal ellipse is made.

Answers

Using the 14c calibration on the x-axis, the approximate age of the neanderthal fossils is (C) 40,110 years old.

What is calibration?Calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy in measurement technology and metrology. A standard could be another known-accuracy measurement device, a device that generates the quantity to be measured, such as a voltage or a sound tone, or a physical artifact, such as a meter ruler. Calibration's goal is to reduce measurement uncertainty by ensuring the accuracy of test equipment. Calibration quantifies and controls measurement errors or uncertainties to an acceptable level.

So, using calibration on the x-axis, the approximate age of the neanderthal fossils came out to be 40,110 years old.

What is the total profit after selling 0 ribbons?

Answers

Using a linear function, we have that:

The rule is P(x) = 0.5x - 75.The total profit after selling 0 ribbons is of -$0.75.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For this problem, when x increases by 10, the profit increases by 5, hence the slope is:

m = 5/10 = 0.5.

Then:

P(x) = 0.5x + b.

When x = 10, P(x) = -70, hence:

-70 = 0.5(10) + b

b = -75.

Hence:

The rule is P(x) = 0.5x - 75.The total profit after selling 0 ribbons is of -$0.75.
