Step-by-step explanation:

Answer:

y = 45/x

Step-by-step explanation:

Here, we want to write an inverse relationship

for an inverse relationship, the product of both variables will be equal to the constant term

Let us have the constant term as k

Thus, we have it that;

xy = k

9 * 5 = k

k = 45

So the inverse function is;

xy = 45

or y = 45/x

if y is a function of x, we can have it as;

f(x) = 45/x

Answer:

2a(a+2b) square metres

Step-by-step explanation:

surface area of a box = 2(lw+wh+lh)

l is the length = a metres

w is the width = a mtres

h is the height = b metres

Substitute into the formula

surface area of a box = 2(a*a+ab+ab)

surface area of a box = 2(a² + 2ab)

surface area of a box = 2a(a+2b) square metres

This give sthe surface area of the box

Answer:

30

Step-by-step explanation:

We can start by writing an equation:

2 + x / 5 = 8

We are adding 2 since we are asking for two more than the quotient, and it is set equal to 8 as given by the problem.

We can subtract 2 from both sides to isolate the x term:

2 + x / 5 = 8

-2             -2

x / 5 = 6

Now, we can multiply by 5 to cancel out the division by 5:

x / 5 = 6

* 5        * 5

x = 30

So, the number is 30.

The requried number is 30, and the equation model is x/5 + 2 = 8.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
In the question, we have given a statement, and using that we have to model an equation,
To model an equation 1 step is to assign a variable.

So let the number be x.
According to the quesiton,
Two is more than the quotient of a number and 5 is equal to 8
x/5 + 2 = 8
x/5 = 8 - 2
x /5 = 6
x = 5 × 6
x = 30

Thus, the requried number is 30, and the equation model is x/5 + 2 = 8.

Answer:

p = -2

Step-by-step explanation:

Start by dividing both sides by 81 to get the power by itself.

[tex]3^p \cdot 81 = 9\\\\3^p=\frac{9}{81}=\frac{1}{9}[/tex]

Write the fraction using a power of 3.

[tex]3^p=\frac{1}{3^2}\\\\3^p=3^{-2}\\\\p=-2[/tex]

This assumes you know about negative exponents:  [tex]a^{-n}=\frac{1}{a^n}[/tex]

Given:

The vertices of a triangle JKL are J(0, 2), K(–1, 2), and L(0, –3).

To find:

The coordinates of the image of point J after a dilation with a scale factor of 3.

Solution:

If a figure is dilated by a scale factor of k, then

[tex](x,y)\to (kx,ky)[/tex]

The given triangle JKL dilated by a scale factor of 3. So,

[tex](x,y)\to (3x,3y)[/tex]

The coordinates of point J are J(0,2). By using the above rule, we get

[tex]J(0,2)\to J'(3(0),3(2))[/tex]

[tex]J(0,2)\to J'(0,6)[/tex]

Therefore, the coordinates of the image of point J after a dilation with a scale factor of 3 are J'(0,6).

Answer:

V would equal -7.1.

Step-by-step explanation:

It appears you have set the decimal points as commas. Let's remove that and replace it with decimal points. (AkA ".")

First, we move every term with "V" in this problem to the left.

-9.45 - 3.3v = 13.98

Next, we add -9.45 to 13.98 which equals 23.43.

We then make 3.3v negative.

-3.3v = 23.43

We then divide 23.43 and 3.3v by 3.3.

We cancel out 3.3v to leave 23.43/3.3.

We can now divide 23.43 by 3.3 to get -7.1.

V = -7.1

Answer:

V would equal -7.1.

Answer:

C. Add the exponents

Step-by-step explanation:

The given expression is presented as follows;

6·x·y²·z⁴·2·x²·y⁵·z

The expression can be rearranged by according to like terms as follows;

6·2·x·x²·y²·y⁵·z⁴·z = 3·2·2·x·x²·y²·y⁵·z⁴·z

By the law of indices, we add the exponents of the like terms to simplify the expression as follows;

3·2·2·x·x²·y²·y⁵·z⁴·z = 3·2⁽¹⁺¹⁾·x⁽²⁺¹⁾·y⁽⁵⁺²⁾·z⁽⁴⁺¹⁾ = 3·2²·x³·y⁷·z⁵

In order to simplify the expression the step Tim needs to use for each variable's exponent is to add the exponents.

Answer:

Step-by-step explanation:

So, I started solving this problem by writing all the possible options, then pairing them each up with a fruit and drink..

...But when I read the question again, I noticed I forgot to leave out the fruit, as this question states that you're trying to retrieve "a turkey sandwich and a bottle of water.."

Well, oof.

Despite that, I'm still giving this answer as if it never left out the fruit. So, let's see what we need to do.

To find all the possible lunch options, I started out by writing down one of our meats, Turkey. As per requested, I made every possible turkey combination that included a fruit and drink, which gave me this:

Same for the ham:

Putting these together, this gives up 8 different lunchbox combinations. If we're trying to get one and we randomly select it, then we have a 1/8 chance of grabbing the turkey sandwich and a bottle of water....

..and a fruit.

Hope this helped!

Answer:

Step-by-step explanation:

Answer:

a. d(x) = x

b. yes

Step-by-step explanation:

a. since c(x) = [tex]x^{2}[/tex] + 1

c(d(x)) = (d(x))^2 + 1 (replace x with d(x))

that means d(x) has to be x for c(d(x)) to equal [tex]x^{2}[/tex] + 1

b. for example if you use 2 as x, c(d(x)) will equal 5 since d(x) = 2 and [tex]2^{2}[/tex] + 1 = 5

d(c(x)) will also equal 5 because c(x) = [tex]2^{2}[/tex] + 1 = 5 and d(c(x)) = c(x) = 5

Answer:

6957  inches squared

Step-by-step explanation:

surface area of a cone  = πr × (r + √[h² + r²])

h = height

r = radius = 4/2 = 2 inches

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

(3.14 x 2) x (2 + √5² + 2²) = 6.28  x 7.39 = 46.38 inches squared

the amount of coated paper needed for 1 cup is 46.38 inches squared

Amount needed for 150 cups = 46.38 x 150 = 6957

Answer:

1: C =69.3 m2

2: F = ll units

3. C:  3 in.

4. G =65 units

Step-by-step explanation:

1: C =69.3 m2

We see from the figure that height of the parallelogram ABCD is not known and the base is 10 m

Taking the right angled triangle the height is given by

Sine theta= height/hypotenuse

height = hypotenuse* sine theta

         = 8* sine 60

         = 8* 0.866= 6.928

Area of parallelogram= base * height

                   = 10 * 6.928

                   = 69.28

                  =69.3 m²

2: F = ll units

We see from the figure that height of the parallelogram DEFG is not known and the base is 13 cm

Area of parallelogram= base * height

                  143 = 13 * height

           Height = 143/13= 11 units

3. C:  3 in.

The area of the triangle = 1/2 * base * height

Let the height be x then the base is 3x

54= 1/2*x*3x

54= 3x²/2

27= 3x²

x²=27/3

x²= 9

x= 3

The height is 3 inches

4. G =65 units

Area of the quadrilateral = 1/2 *PR*QO + 1/2 *PR*OS

                                      = 1/2*13*4+ 1/2*13*6

                                        =26+ 39

                                        = 65 units
