Lee is buying roses. If each rose costs $2, which equation does not describe how many roses Lee might buy for $24?

Answers

Answer 1

Answer:

[tex](a)\ y = 2x[/tex]

[tex](b)\ x= 12[/tex]

Step-by-step explanation:

Given

[tex]rose = \$2[/tex]

Solving (a): The equation

Let

y = total amount

x = number of roses

So:

If [tex]x = 1, y = 2[/tex]

If x = x.

[tex]y = 2* x[/tex]

[tex]y = 2x[/tex]

Solving (a): Number of roses for $24

This implies that

[tex]y = 24[/tex]

So:

[tex]y = 2x[/tex]

[tex]24 = 2x[/tex]

Divide both sides by 2

[tex]12 = x[/tex]

[tex]x = 12[/tex]

Answers

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

Two more than the quotient of a number and 5 is equal to 8

Answers

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.

What are equation models?

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.

Given y varies inversely as x, and y = 5 when x = 9. *Write the inverse function

Answers

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

Mrs. James is making snow cone cups using a special-coated paper to sell at a school
fundraiser. The snow cone cups have a diameter of 4 inches across the widest part of the
snow cone and are 5 inches tall.
What value most closely represents the amount of coated paper in square inches that Mrs.
James will need to make 150 snow cone cups?

Answers

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

In order for Tim to simplify the expression below, what step will he need to use for each variable's exponent? 6 x y^2 z^4 2 x^2 y^5 z A Divide the exponents B Multiply the exponents C Add the exponents D Subtract the exponents

Answers

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.

Solve for v.

–9,45 − 6,1v = –2,8v + 13,98

Answers

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.

Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)

The factors are + 1 and + 7 , since

1 × 7 = 7 and 1 + 7 = 8 , then

x² + 8x + 7 = (x + 1)(x + 7) ← in factored form
