A designer builds a model of a bicycle. The finished model is exactly the same shape as the original, but smaller. The scale factor is 2:7. (a) Find the ratio of the height of the model to the height of the original. (b) Find the ratio of the surface area of the model to the surface area of the original. (c) Find the ratio of the volume of the model to the volume of the original. Write these ratios in the format m:n.

We know that there are tomato juice, orange juice, and cherry juice bottles in a ratio of 4:3:4, respectively.

As you can observe in the given ratio, to get 30 orange juice, we have to multiply it by 10. So, if we multiply the whole ratio, we obtain the following

This means that 30 orange juice bottles are in the same ratio as 40 tomato juice bottles and 40 cherry juice bottles.

The original price of the pants is $28.23

Let the original price of the pants be 100x

Then, the discount given will be 15x

and the sale price would be 85x

According to the question, the sale price given is 24

So,

85x = 24

x = 24÷85

x= 0.2823

Therefore,

100x = 100*0.2823

= 28.23

Hence, the original price of the pants is $28.23

(a) The angles are exterior angles.

(b) The angles are alternate exterior angles and are equal to each other.

(C) The value of x is 6 and the measure of angle 27x - 5 is equal to 130°.

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Two parallel lines and a transversal cutting them are given. The two angles are 130° and 27x - 5.

Both angles are exterior angles.

The angles 130° and 27x - 5 are alternate exterior angles and are equal.

Now,

130° = 27x - 5

Adding 5 on each side.

27x - 5 + 5 = 130 + 5

27x = 135

Dividing each side by 27

x = 5°

Therefore, substituting the value of x.

27x - 5 = 27(5) - 5 = 135 - 5 = 130°

Hence, the measure of angle 27x 0 5 = 130°

• A triangle with a base of 40 inches and a height of 30 inches.

Thus:

The area of the arrow is 1200 square inches.

The measure of angle p is 213 degrees

The possible question is added at the end of the solution and as an attachment

From the attached figure, we have the following angles

Also, from the attached figure:

We can see that the three angles named above are formed by lines that meet at a point (say the point of origin)

When multiple lines meet at a point, the sum of the angles formed at this point is 360 degrees

This means that

Angle 1 + Angle 2 + Angle 3 = 360

Substitute the known values in the above equation

So, we have

p + 57 + 90 = 360

Evaluate the sum in the above equation

So, we have

p + 147 = 360

Evaluate the like terms in the above equation

So, we have

p = 213

Answer: My new music player has a capacity of  3.6*10^11 bytes.

Step-by-step explanation: Scientific notation of a number is going to be in the form of a*10^b where a is a number greater than 1 but less than 10 which is then multiplied by the appropriate power of 10 so that the numbers are equal. This allows us to see numbers concisely without getting distracted by the sheer number of zeroes in some numbers. For 360, since 3.6 is between 1 and 10, we use that for a. To get 3.6 to equal 360 you have to move the decimal two places to the right, or multiply by 10^2, so b=2. Since this is in gigabytes, and giga=10^9, to express the answer in bytes we just multiply 10^2 to 10^9=10^11

To make a profit with the revenue of R=113.95x and cost of C =93x + 750 the value of x is 36units.

As given in the question,

The revenue for selling x units of a product is R = 113.95 x.

The cost of producing x units is C = 93 x + 750

To make a profit, the revenue must be greater than the cost.

R > C

113.95x > 93x +750

Subtract 93x from both the sides

113.95x -93x +93x-93x +750

⇒20.95x > 750

⇒x > 750/20.75

⇒x>35.799

Value of x to produce a profit is 36units

Therefore, to make a profit with the revenue of R=113.95x and cost of C =93x + 750 the value of x is 36units.

Answer:

1 1/2

Explanation:

We can illustrate the relationship between addition and subtraction using the following example:

If we have 5 - 3 = 2, then we can say that 2 + 3 = 5

So, in this case, the result of 3 1/4 - 1 3/4 is a number that added to 1 3/4 is equal to 3 1/4. Then, the answer will be 1 2/4 because:

Because 1 3/4 is equivalent to 7/4 and 1 2/4 is equivalent to 6/4.

Finally, 2/4 is equivalent to 1/2, so we can rewrite the result 1 2/4 as follows:

1 2/4 = 1 1/2

Car B travelled with the rate of speed of 40mph .

In the question ,

it is given that ,

Car B travelled 5mph slower than Car A .

let the rate of speed at which Car B travelled be x mph.

So , the rate of speed of Car A is = (x+5) mph

Car A travelled the distance in 4 h , with the speed of (x+5) mph ,

the value of T = 4 h and R = (x+5) mph

So, by the formula R*T=D ,

we get ,the distance travelled by Car A = 4(x+5) miles .

Car B travelled the distance in 4.5 h , with the speed of x mph .

the value of T= 4.5h  and R = x mph

So, by the formula R*T=D,

we get , the distance travelled by Car B = 4.5*x = (4.5x) miles .

Since , both the cars travelled the equal distance ,

we get ,

4(x+5) = 4.5x

4x+20=4.5x

4.5x-4x = 20

0.5x= 20

The $7,000 worth of purchase and payment of $5,000 before the three months deadline gives the amount owed at 2.49% monthly compound interest rate as $2,153.15

Owed: $2,153.15

Compound interest accounts for the interest that is earned on an interest, such that the interest rate is compounded on an initial amount.

The given parameters are;

The amount of the items purchased from the store = $7,000

The amount of down payment required = 10%

The amount paid in three months = $5,000

Monthly interest on amount owed after three months = 2.49%

Required;

The amount owed after payment of $5,000 before three months

Solution;

Using the compound interest formula, we have;

[tex] \displaystyle{A = P \cdot \left(1 + r \right)^{n} }[/tex]

Where;

A = The amount owed

P = The amount loaned = $7,000 - $5,000 = $2,000

r = Monthly interest rate = 2.49%

n = The number of months = 3 months

Which gives;

[tex] \displaystyle{A = 2000 \times \left(1 + 0.0249 \right)^{3} \approx 2153.1509}[/tex]

To find the y =?

Now, According to the question:

Because the graph of a quadratic goes through point (-8 ,0) and point   (2, 0)

So, supposing the equation of the quadratic function is  

y = a [x - (-8)] (x - 2) = a (x + 8)(x - 2)

The graph passes through the point (-6, 16)

So, -16 = a(-6 + 8)(-6 -2)

=> -16 = a x 2 x (-8)

=> a = 1

So, y = (x + 18)(x - 2)

y = [tex]x^{2}[/tex] + 8x - 2x - 16

y = [tex]x^{2}[/tex] + 6x - 16

The resulting exponent form is, 1/9¹⁰

Exponent:

Exponent is used to show repeated multiplication of a number by itself. For example,

7 × 7 × 7 can be represented as 7³

Here, the exponent is ‘3’ which stands for the number of times the number 7 is multiplied.

Given,

Here we have the exponent form is,

9⁻⁸x9⁻²

Here we have to use the product property and then we have to get rid of negative exponents.

First step is to use the product property,

We know that, the product property states that,

for any non-zero term a,

yᵃ x yᵇ = yᵃ⁺ᵇ

where a and b are real numbers.

So, the given expression is written as,

=> 9⁻⁸⁺⁽⁻²⁾

=> 9⁻⁸⁻²

=> 9⁻¹⁰

Now the second step is to get rid of the negative components,

As per the rule, the exponent is negative, we can change the exponent into positive by writing the same value in the denominator and the numerator holds the value 1.

So, the value is,

=>  9⁻¹⁰ = 1/ 9¹⁰
