Answer:

$2.16

Step-by-step explanation:

if the store sells 9 cm for $0.72

they are selling 27 cm now which is 3 times the amount of 9

so if 27 is 3 x the amount of cm than we need to triple to amount of the cost to.

and 0.72 x 3 is 2.16.

Unit rate

Answer:

1½ miles/day .

Step-by-step explanation:

To find:-

Answer:-

It is given that the crew made 8¼ miles of road in 5½ days . To find the rate of work done , simply divide the total length of road nade by total time taken . That would be , ( rate is represented by "r" . )

[tex]:\implies \sf r = 8\dfrac{1}{4}\div 5\dfrac{1}{2} \ miles/day\\[/tex]

Convert the mixed fraction into improper fraction.

[tex]:\implies \sf r = \dfrac{33}{4}\div \dfrac{11}{2} \ miles/day \\[/tex]

For dividing them , multiply the reciprocal of 11/2 by 33/4 as ,

[tex]:\implies \sf r = \dfrac{33}{4}\times \dfrac{2}{11} \ miles/day\\[/tex]

[tex]:\implies \sf r = \dfrac{3}{2} \ miles/day \\[/tex]

[tex]:\implies \sf \pink{ r = 1\dfrac{1}{2}\ miles/day } \\[/tex]

Hence the unit rate of constructing the road is 1½ miles/day .

How to measure an angle with a protractor:

Place the midpoint of the protractor on the VERTEX of the angle.

Line up one side of the angle with the zero line of the protractor (where you see the number 0).

Read the degrees where the other side crosses the number scale.

Step-by-step explanation:

you can use a protractor to measure and draw angles. To measure angles with a protractor, first place the center point along the bottom edge of the protractor over the vertex of the angle you're measuring. Line up the bottom edge of the protractor with one leg of the angle.

Answer:

81/5 or 16 1/5.

Step-by-step explanation:

First convert the mixed number to an improper fraction:

3 6/7

= (3*7 + 6) / 7

=  27/7.

So we have

27/7 / 5/21

Invert the second fraction and multiply:

= 27/7 * 21/5

= (27*21) / (7*5)

= (27*3) / 5        ( as 21/7 = 3)

= 81/5

= 16 1/5.

If you vertically compress the absolute value parent function, f(x) = 1x1, by a factor of 3 then the equation of the new function is g(x) = (1/3)|x|

A relation is a function if it has only One y-value for each x-value.

The absolute value function, f(x) = |x|, has a "V" shape with the vertex at (0, 0).

f(x) can also be called as parent function.

A parent function is the simplest function that still satisfies the definition of a certain type of function

When we vertically compress the graph by a factor of 3, we are multiplying the y-value by 1/3.

So the new function g(x) can be expressed as:

g(x) = (1/3) f(x)

g(x) = (1/3)|x|

Hence, if you vertically compress the absolute value parent function, f(x) = 1x1, by a factor of 3 then the equation of the new function is g(x) = (1/3)|x|

The previous price given the percentage decrease is 400.

It follows from the task content that the previous price of the commodity is required;

let, x = previous price

New price = 340

Percentage decrease = 15%

Hence, it follows from the given information that;

340 = x - (15% × x)

340 = x - (0.15x)

340 = 0.85x

x = 340/0.85

x = 400

Therefore, the previous price given the percentage decrease is 400.

After 1.959 years Evan's money has doubled in value and at that time Brandon have $43,481.78 in his account.

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

Let's suppose, after t time, Evan's money has doubled in value.

[tex]\rm 2P = P(1+\dfrac{0.37}{4})^{4t}[/tex]

After solving

x = 1.959 years

Use x = 1.959 years to get how much money would Brandon have.

[tex]\rm A = P e^{rt}[/tex]

[tex]\rm A = 41000\times e^{0.03\times 1.959}[/tex]

A = $43,481.78

Thus, after 1.959 years Evan's money has doubled in value and at that time Brandon have $43,481.78 in his account.

Minimum number of hours which a person need to rent a tube in order for the second company to be a better deal is more than 2.5 hours.

A mathematical model is the model which is used to explain any system, the effect of the components by study and estimate the functions of systems.

Two companies (first and second) offers river tubing trips and the rates of them are as follows: The first company charges $7.50 rental fee for one tube, with a charge of $3.00 an hour.

For the x hours, the charge of the company is,

7.50+3.00x

The second company charges $10.50 rental fee for one tube with a charge of $2.00 an hour. For the x hours, the charge of the company is,

10.50+2.00x

Let x is the hour at which the cost of both companies are equal. Thus,

7.50+3.00x=10.50+2.00x

3x-2x=10.5-7.5

x=2.5

Thus, the minimum number of hours which a person need to rent a tube in order for the second company to be a better deal is more than 2.5 hours.

Answer:

D. y = -1/8(x-2)² - 3

Step-by-step explanation:

General eqaution of a parabola : y = a(x-h)² + k where (h,k) is the vertex and a determines whether the parabola goes up or down as well as the width of the parabola

step 1 identify vertex

the vertex is the point that starts the curve

the vertex appears to be at (2,-3)

step 2 plug in h and k using the x and y values of the vertex

again we have  y = a(x-h)² + k where (h,k) is the vertex

here the vertex is (2,-3) so h = 2 and k = -3

we get y = a(x-2)² - 3

because the curve goes down a must be negative 1/8

so the final equation would be y = -1/8(x-2)² - 3 meaning D would be the answer

Answer:

8mm

Step-by-step explanation:

The volume of a cylinder is the base area times the height. The base is a circle, and we are not given the radius, so let the radius of the circle of the base of the circle be r. The area of a circle would be [tex]\pi r^{2}[/tex]. This multiplied by the height, which is 15, is [tex]15\pi r^{2}[/tex]. The volume is given to be 753.6, so we can make this an equation:

753.6 = [tex]15\pi r^{2}[/tex]

We are told to use 3.14 for pi, so:

[tex]753.6 = 15 * 3.14 * r^{2}[/tex]

[tex]r^{2} = 16[/tex]

[tex]r = 4[/tex]

The diameter is twice the radius, so the diameter is 8mm.

Answer:

8 mm

Step-by-step explanation:

Formula to find volume :

Volume (cylinder) = πr²h

⇒ 753.6 = 3.14 × r² × 15

⇒ 47.1 × r² = 753.6

⇒ r² = 753.6/47.1

⇒ r² = 16

⇒ r = 4 mm

Relating radius and diameter :

Diameter = 2 × Radius

⇒ Diameter = 2 × 4 mm

⇒ Diameter = 8 mm

Using proportions, it is found that the coordinates of p in the line segment are given as follows: (-1,2).

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the points are:

p is two-thirds the length of the line segment from a to b, hence:

[tex]p - a = \frac{2}{3}(b - a)[/tex]

For the x-coordinate, we have that:

[tex]x - 9 = \frac{2}{3}(-6 - 9)[/tex]

x - 9 = -10

x = -1

For the y-coordinate, we have that:

[tex]y + 8 = \frac{2}{3}(7 - (-8))[/tex]

y + 8 = 10

y = 2.

The coordinates of p are (-1,2).
