Answer:

Substraction

Step-by-step explanation:

Given that  

The amount paid in the year 2018 is $3,200

And, in the year 2019 the amount paid is $3,516'

We need to find the differnece between two years so how we can find

Basically we need to subtract the amount i.e.

= $3,516 - $3,200

= $316

hence, the difference is of $316 from 2018 to 2019

Step-by-step explanation:

Since WZ=1287ft .XY=54ft

WX is congruent to YZ

so WX= 1/2 (128-54)

= 1/2 x(<—times) 74

=37ft

WY= WX + XY

=37+54

= 91ft

The value of c such that f(c) equals the average value of the function over [-5,1] is c = -3.

To find the average value of a function over an interval, we need to calculate the definite integral of the function over that interval and divide it by the length of the interval.

First, let's find the definite integral of f(x) over the interval [-5,1]:

∫[-5,1] -4x + 2 dx

Using the power rule of integration, we can integrate term by term:

= [-2x^2 + 2x] evaluated from -5 to 1

= [(-2(1)^2 + 2(1)) - (-2(-5)^2 + 2(-5))]

= [(-2 + 2) - (-50 + (-10))]

= [0 - (-60)]

= 60

Now, let's find the length of the interval [-5,1]:

Length = 1 - (-5) = 6

To find the average value of the function, we divide the definite integral by the length of the interval:

Average value = 60 / 6 = 10

To find c such that f(c) equals the average value, we set -4c + 2 = 10 and solve for c:

-4c + 2 = 10

-4c = 10 - 2

-4c = 8

c = 8 / -4

c = -2

Therefore, the value of c such that f(c) equals the average value of the function over [-5,1] is c = -2.

The value of c is -2, such that f(c) equals the average value of the function f(x) = -4x + 2 over the interval [-5,1]. The average value of the function is 10, and by solving the equation -4c + 2 = 10, we find that c = -2.

By applying total cost concept, it can be concluded that the expression represents the total cost is 1.45d (option A).

Algebra is a branch of mathematics that uses symbols and mathematical operations, such as addition, subtraction, multiplication, and division to solve problems.

It is usually used to solve a problem in various fields of study, such as chemistry, biology, economics, and so on.

One of the most familiar uses of algebra is how to calculate the total cost:

Total cost = n x p , where:

n = number of products

p = product price per piece

We know that Jim is going to buy donuts for his family:

p = $1.45

n = d

So the total cost can be calculated by multiplying 1.45 by d, which equals 1.45d.

Thus the expression represents the total cost is 1.45d (option A).

Answer:

The equation representing the relationship is;

Amount charged to work a dog once a day = $1.25 * Number of days

Step-by-step explanation:

Here, we want to find the equation representing the relationship between the charges and the number of days

Firstly, he charges $6.25 to walk a dog a day for 5 days, the amount charged per day will be $6.25/5 = $1.25

For the 7 days, amount charged = 8.75/7 = $1.25

This means he charges an amount of $1.25 to walk a dog once a day

The equation that represents the relationship is thus;

Amount charged = $1.25 * Number of days

B. y = 5x² represents a proportional relationship.

In a proportional relationship, the ratio of the dependent variable (y) to the independent variable (x) is constant. In this equation, as x increases, y also increases by a constant factor (5 times x). This indicates that the two variables are proportional to each other.

In A. y = 4x + 1 and C. y = 9, there is no constant ratio between y and x, so they do not represent proportional relationships.

Step-by-step explanation:

Formula:

1/3(area of the base x height)

1/3 [2.175(2.175)(6.3)]

1/3(4.730625)(6.3)

1/3(29.8029375)

9.9343125

Is the perimeter of the base is 8.7, we need to divide that by 4 (2.175) to find out the side length of the square.  The area of the square, we need to multiply 2.175 by 2.175.

9.9343125 rounded to the nearest tenth is 9.9

The volume of the gas at a pressure of 3.5 atm would be 1.196 liters, which is smaller than the initial volume at 1.9 atm. This is because as the pressure of a gas increases, its volume decreases, assuming constant temperature and number of particles.

To find the new volume of the gas, we can use the Boyle's Law equation, which states that the pressure and volume of a gas are inversely proportional to each other at constant temperature. Therefore, we can write:
P1 x V1 = P2 x V2
where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.
Plugging in the values given in the question, we get:
1.9 atm x 2.2 L = 3.5 atm x V2
Solving for V2, we get:
V2 = (1.9 atm x 2.2 L) / 3.5 atm
V2 = 1.196 L
Therefore, the volume of the gas at a pressure of 3.5 atm would be 1.196 liters, which is smaller than the initial volume at 1.9 atm. This is because as the pressure of a gas increases, its volume decreases, assuming constant temperature and number of particles.

The compound interval for the given interval is (-∞, ∞).

A compound inequality is a combination of two inequalities that are combined by either using "and" or "or". The process of solving each of the inequalities in the compound inequalities is as same as that of a normal inequality but just while combining the solutions of both inequalities depends upon whether they are clubbed by using "and" or "or".

The given intervals are (-∞, -2] or [-3, ∞).

Now, the compound interval is (-∞, ∞)

Thus, the interval notation is -∞<x<∞

The z-score of an appliance that stopped working at 64 months is 2

Standard score or z score in statistics is defined as the number of standard deviations by which that the value of a score is above or below the mean value.

The formula to find the z score of a data is,

z = (x - μ) / σ

Here x is the observed value, μ is the mean and σ is the standard deviation.

Given that,

Mean = 48 months

Standard deviation = 8 months

x = 64 months

Substituting in the formula,

z = (64 - 48) / 8 = 2

Answer:

for me it is a circle

Step-by-step explanation:

Answer:

42 = 8x + 13x

42 = 21x

x = 2

8 = 8c -4(c + 8)

8 = 8c - 4c - 32

8 = 4c - 32

40 = 4c

c = 10

Answer:

42 = 21x

42/21 = x

x = 2

check:

42 = 8*2 + 13*2

42 = 16 + 26

8 = 8c -4*c -4*8

8 = 8c - 4c - 32

8 + 32 = 4c

40 = 4c

The required speed in km/hr are 108km/hr and 25.704km/hr

Given the following conversion rate

Given that the speed of cheetah is 30meters per second. Converting to m/s will give:

30m/s = \(\frac{30m}{1s} \times \frac{1km}{1000m} \times \frac{3600s}{1hr} \\\)

30m/s = 30 * 3.6

30m/s = 108km/hr

For the person with speed of 7.14m/s, the value in km/hr is expresssed as:

7.14m/s = 7.14 * 3.6

17.4cm

Step-by-step explanation

17) In a triangle ABC, BC=8cm, AC=12cm and angle ABC=120

To get the length of AB, we will use the cosine rule

AB² = BC² + AC² - 2(BC)(AC) cos <ABC

AB² = 8² + 12² - 2(8)(12) cos 120

AB² = 64 + 144 - 192cos12

AB² = 208 - (-96)

AB² = 208 +96

AB² = 208 - (-96)

AB² = 304

AB² = 17.4cm
