Answer:

The number of possible chip dip combinations = 5040

Step-by-step explanation:

There are 7 different kinds of chip dip available

The number of chip dip combinations available = 7! combinations

n! = n*(n-1)*(n-2)*........*1

7! = 7 * 6 * 5 * 4* 3 * 2* 1 = 5040

The number of possible chip dip combinations = 5040

Answer:

$29.4

Step-by-step explanation:

I assume the question is based on simple interest since you didn't specify

Using simple interest

Simple interest=P×R×T

Where,

P=principal=$1470

R=interest rate=4%=0.04

T=time=6 months=0.5 year

Simple interest=P×R×T

=1470×0.04×0.5

=29.4

Interest earned=$29.4

Answer:

the price of the socks is 22€

Step-by-step explanation:

To find the value of a pair of socks you first write an algebraic expression for the situation of the problem.

Maria has 52€, she spent 23€ and also she spent in buying the three pairs of socks. You can chose x as the price of one pair of socks, then, Maria spent 3x. In the end Maria is owd 23€.

If you subtract 23€  and 3x to 52€  you obtain a negative value of -13€ . That is:

53 - 3x = -13    (1)

From the last equation you obtain x:

- 3x = - 13 - 53

-3x = - 66

x = (66/3) = 22

hence, the price of the socks is 22€

Answer:

the number of tomatoes he gathered for 3 days = 3 × x = 3x  

Step-by-step explanation:

According to the question Stan gathered x number of tomatoes every single day for three days. The total number of tomatoes she gathered altogether can be calculated below.

The number of tomatoes she gathered daily = x

The number of tomatoes she gathered for 3 days will be the product of the daily number of tomatoes she gathered(x) and the number of days she gathered it(3).

Therefore,

the number of tomatoes he gathered for 3 days = 3 × x = 3x  .

Or you could calculate the number of tomatoes she gathered for that 3 days by summing the number of tomatoes she had daily for that 3 days .

The firs day she gathered x number of tomatoes , the second day another x number and finally the last day another x number of tomatoes. Therefore,

x + x + x = 3x

Answer:

111.58 feet

Step-by-step explanation:

Given that the length of the string (AB in the attached diagram) is 120 feet.

Selena (at point D) is standing 24 feet from point A, where the kite is attached to the ground.

Since the kite is directly above Selena's head, the problem forms a right triangle.

Using Pythagoras theorem

[tex]|AB|^2=|BD|^2+|AD|^2\\120^2=|BD|^2+24^2\\|BD|^2=120^2-24^2\\|BD|^2=13824\\|BD|=\sqrt{13824} \\|BD|=117.58$ ft[/tex]

Serena's height (CD=6 feet)

The distance of the kite above her head is BC in the drawn diagram.

Therefore:

|BD|=|BC|+|CD|

117.58=|BC|+6

|BC|=117.58-6

|BC|=111.58 feet

The kite is approximately 111.58 feet above Selena's head/

Answer:

5+4x=25

Step-by-step explanation:

You already know you bought 1 $5 magazine so that is the constant. And the question asks how many erasers you bought to equal $25. So to write the equation you know it equals 25 and the 5 is constant, if each eraser is $4 then the x goes with the 4 making it, 5+4x=25

Answer:

The answer to the far left/the Blue Answer.

Step-by-step explanation:

The reason why is because if 1 magazine was the price of $5, that would mean that the total of the erasers AND the magazine equals 25 dollars, as said in the statement. This means that when subtracting 5 dollars from 25 dollars, there are 20 dollars left. This means that if there were 4 erasers, that means that 20 dollars divided 4 erasers equals 5 dollars. This means that each eraser costs 5 dollars, making the Blue Answer/Statement true.

Answer:

28043.3 [tex]m^{3}[/tex]

Step-by-step explanation:

Formula for volume of a hemisphere can be termed as:

[tex]V = \dfrac{2}{3} \pi r^{3}[/tex]

where [tex]r[/tex] is the radius of hemisphere

Please refer to the figure attached for the sample figure of a hemisphere.

We are given here, diameter of hemisphere = 47.5 m

Relation between diameter and radius is given as :

[tex]r = \dfrac{d}{2}[/tex]

where, [tex]r[/tex] is the radius and

[tex]d[/tex] is the diameter.

So, [tex]r = \dfrac{47.5}{2}\ m[/tex]

Volume is:

[tex]V = \dfrac{2}{3} \pi (\dfrac{47.5}{2})^3\\\Rightarrow \dfrac{2}{3} \times 3.14 \times (\dfrac{47.5}{2})^3\\\Rightarrow 28043.3\ m^3[/tex]

Hence, volume of given hemisphere is 28043.3 [tex]m^{3}[/tex].

Answer:

115.7 km/h

Step-by-step explanation:

velocity = distance/time

velocity = (0.9 km)/(28 s) = 0.032143 km/s

The velocity is 0.032143 k/s. The question is answered, but since km/s is not a common unit of speed, we can convert to a more common unit of speed such as km/h.

velocity = (0.9 km)/(28 s)[(3600 s)/(1 h)] = 115.7 km/h

Answer:

1. y = -3x + 5

2. y = 1/4x - 2

Step-by-step explanation:

y=mx+b

1. 5 = -3(0) + b, so b = 5

y = -3x + 5

2. (-2-(-1))/(0-4) = -1/-4 = 1/4

-2 = 1/4(0) + b, so b = -2

y = 1/4x - 2

Answer: -3x+5

Answer:

0.5 Inches

Step-by-step explanation:

1/16=.0625 which is about .1 for estimating purposes

.1 on Saturday + .4 on Sunday = .5 inches of rain over the two days

Answer: 1.5 inches

Step-by-step explanation:

"The amount of rain that fell over two days" means the sum of the two amounts of rain that fell on Saturday and Sunday.

[tex]1\frac{1}{16} +0.4=1\frac{10}{160} + \frac{4}{10} = 1\frac{10}{160} + \frac{64}{160} = 1\frac{74}{160}[/tex]

This number is close to [tex]1\frac{80}{160}[/tex], which is 1.5 inches.

Answer:

yes, they're equivalent

Answer:

Yes ,they are equivalent.

Step-by-step explanation:

2(n + 5) + 4(n + 5) ; here since n+5 is a common factor so we can factor it out :

2(n + 5) + 4(n + 5) = (n + 5)×(2 + 4)

                             = (n + 5)×(6)

                             = 6(n + 5)

Answer:

[tex]f(3) = f(3 - 2) \times f(3 - 1)[/tex]

[tex]f(3) = f(1) \times f(2)[/tex]

[tex]f(3) = 4 \times 25[/tex]

[tex]4 \times 25 = 100[/tex]

12 is the measure of the value of f(3).

Based on the given information, we have f(1) = 4 and f(2) = 25.

To determine the value of f(3), we will use the recursive formula

f(n) = f(n - 2) * S(n - 1), where:

S represents the successor function.

Determine f(3):

f(3) = f(3 - 2) * S(3 - 1)

f(3) = f(1) * S(2)

f(3) = 4 * 3

f(3) = 12

Therefore, the value of f(3) from the sequence is 12.

Answer:

It will take 4 years

Step-by-step explanation:

Here, given the exponential equation that approximates the cost of a car after a certain amount of time, we are tasked with calculating the amount of time it will take to be worth a certain amount.

The exponential equation that approximates the cost of the car is given as;

V = 2,000(0.8)^x

Now, our V = 820 but we want to calculate x which gives the number of years. Substituting this value of V, we get;

820 = 2000(0.8)^x

divide through by 2000

0.41 = 0.8^x

Take the log of both sides

log 0.41 = log 0.8^x

log 0.41 = xlog 0.8

x = log 0.41/log 0.8

x = 3.99 which is approximately 4 years

Answer:

Plug in your x and y values and use the information

The value of the expression  14 - (2x - y) when x = 3 and y = 2 is 10.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given,  14 - (2x - y) to obtain the value of the expression when x = 3 and y = 2 we'll imply replace the numerical values of x and y which is,

Answer:

The distance from point P to point V = 17 ft.

Step-by-step explanation:

A rectangular prism is simply a cuboid,

The image describing the cuboid described, as obtained from from internet is attached to this solution. (It is redrawn to avoid the solution being removed due to violation of community guidelines)

From the image, PR, PS and SR form a right angled triangle on the case of the cuboid.

With PR as the hypotenuse side, using Pythagoras theorem,

(PR)² = (PS)² + (PR)²

(PR)² = 12² + 9² = 144 + 81 = 225

PR = √225

PR = 15 ft.

On a second evaluation, the required length, PV, PR and RV form another right angled triangle with PV as the hypotenuse side, using Pythagoras theorem again,

(PV)² = (PR)² + (RV)²

(PV)² = 15² + 8² = 225 + 64 = 289

PV = √289

PV = 17 ft.
