Answer:

42/5% as a decimal is 8.4

Based on the amount that Luis earns per week, and the state flat rate income tax, Luis's state income tax for the week is $11.66

First, find out what Luis's earnings for the week were:

= Number of hours worked for the week x Earnings per hour

= 28 x 11.90

= $333.20

The state income tax is therefore:

= Amount earned weekly x State tax rate

= 333.20 x 3.5%
= $11.66

In conclusion, the state income tax of Luis for the week comes to an amount of $11.66.

Step-by-step explanation: The measure of the exterior angle is equal to the sum (adding together) of the interior angles. 42+46=88.

The cost for each pound of walnuts is $ 2.25 and each pound of chocolate chips is $ 1.5.

We are given that:

Cost of 4 pounds of walnuts and 8 pounds of chocolate chips = $ 21.

Cost of 2 pounds of walnuts and 3 pounds of chocolate chips = $ 9.

Let the cost of pounds of walnuts be x and the cost of pounds of chocolate chips be y.

So, we get the following equations:

4 x + 8 y = 21    …(1)

2 x + 3 y = 9

2 x = 9 - 3 y

x = 1 / 2 (9 - 3y)   …(2)

Put the value of x in (1)

4 ( 1 / 2 (9 - 3y) ) + 8 y = 21

2(9 - 3y) + 8 y = 21

18 - 6 y + 8 y = 21

2 y + 18 = 21

2 y = 21 - 18

2 y = 3

y = 3 / 2

y = 1.5

x = 1 / 2 (9 - 3y)

x = 1 / 2 ( 9 - 4.5)

x = 1 / 2 ( 4.5)

x = 2.25

Therefore, we get that, the cost for each pound of walnuts is $ 2.25 and each pound of chocolate chips is $ 1.5.

Answer:

5 (1 + 5)

Step-by-step explanation:

It would be this because the 5 would distribute itself multiplying into the 1 and other 5 equaling 5 + 25 and it is in the distributive property.

The equation of the line in y = mx + c form is y = (-25/4)(x) + 5.

Here, we are given a line as shown in the figure.

Let us take 2 points that the line passes through. We can see that the line passes through (0, 5) and (0.8, 0)

Now, we have two points, we can find the slope of the line.

Slope is taken to be m. Thus,

m = (y2-y1)/ (x2-x1)

here, (x1, y1) = (0, 5)

and (x2, y2) = (0.8, 0)

Therefore,

m = (0-5)/ (0.8 -0)

m = -5/0.8

we can simplify this as follows-

m = -50/8

m = -25/4

Thus, the slope of the line is -25/4.

Now, we already know that  (0, 5) is a point on the line. Thus, the y intercept of the line is 5.

⇒ c = 5

Now, substituting the values in the equation we get-

y = (-25/4)(x) + 5

Thus, the equation of the line in y = mx + c form is y = (-25/4)(x) + 5.

Answer:

The car passed the truck after 60 minutes.

Step-by-step explanation:

We should first find how far the truck was from the entrance to the highway when the car entered (after 11 minutes). We know that the distance travelled is the product of the time and speed, therefore, the location of the truck is given by [tex]d = 60 * 11 = 660[/tex].

Now we can build functions representing the distance from the entrance of both vehicles, in respect to the time travelled.

Truck's Function
[tex]x_0 = 660m \\ v = 60mph \\ \to x(t) = 660m + 60t[/tex]

Car's Function
[tex]x_0 = 0m \\ v = 71mph \\ \to x(t) = 71t[/tex]

Finally, we can equalize both functions to find out at what time the car passed the truck (when their graphs intercepted):

[tex]660 + 60t = 71t \\ \to 660 = 11t \\ \to t = 60m[/tex]

Saying that the populations of the U.S. and India went up by 2.6 million and 15.8 million respectively is an absolute comparison.

The relative comparison of the populations of the U.S. and India from 2015 to 2016 would be 0.81% and 1.21% respectively.

In terms of population growth, an absolute comparison is made when the increase in population is denoted through the use of whole numbers. No percentages or fractions are used.

By simply mentioning that the U.S. population rose by 2.6 million and that of India rose by 15.8 million is therefore absolute.

The relative comparison is found as:

= Change in population / Population in 2015

For the United States:

= 2.6 million  / 320.7 million

= 0.81%

For India:

Answer:

The maximum number of people that can be invited is 65.

Step-by-step explanation:

Based on the information given in the question, the equation to solve the question will be:

80 + 37x = 2500

80+37x=2500

Step 1: Simplify both sides of the equation.

37x+80=2500

Step 2: Subtract 80 from both sides.

37x+80−80=2500−80

37x=2420

Step 3: Divide both sides by 37.

37x/37 = 2420/37

x= 2420/37

x = 65.4

Solution :  Distance between (-1/2, -1) , (5/8, -1) = .75

Distance Formula :

Distance between two points can be evaluated if we know the c

[tex]\sqrt{{(y2-y1)^{2} } +(x2-x1)^{2}][/tex] = XY

The difference between the x-axis coordinates gives the horizontal distance and the difference between the y-axis coordinates gives the vertical distance.

Distance between the points P and Q is calculated as follows:

S and T are the points on the x-axis which are endpoints of two parallel line segments PS and QT respectively.

⇒ PR = ST

Coordinates of S and T are (x1, 0) and  (x2, 0) respectively.

OS =  x1 and OT = x2

ST = OT – OS = x2 – x1 = PR

Similarly,

PS =  RT

QR = QT – RT = QT – PS = y2 – y1

By Pythagoras theorem,

PQ2 = PR2 + QR2

PQ = √[(x2– x1)2+ (y2– y1)2]

Therefore,

Distance between two points (x1,y1) and (x2,y2) is given by:

[tex]\sqrt{{(y2-y1)^{2} } +(x2-x1)^{2}][/tex]

distance between (-1/2, -1) , (5/8, -1)

We need to multiply each coordinate by 3/2.

Considering the definition of an equation and the way to solve it, the number is -3/7.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

The solution of a equation means determining the value that satisfies it. This is, by changing the unknown to the solution, the equality must be true. To solve an equation, keep in mind:

Being "x" a number, and knowing that eight more than six times a number is the same as two less than 8 times the numbe, the equation in this case is:

8 + 6x= 2 - 8x

Solving:

6x + 8x= 2-8

14x= -6

x= (-6) ÷ 14

x= -3/7

Finally, the number is -3/7.

By using basic arithematic operations we concluded that the temperature at 6 pm was - 9.8°F.

Arithmetic operation is the study of numbers and the operations on numbers that are used in all other branches of mathematics. It primarily consists of basic operations like addition, subtraction, multiplication, and division.

The temperature at 09:00 am = -6.9°F.

The tempertaure increased by 5.4°F till noon

So, the final tempertaure at noon = - 6.9°F + 5.4°F

                                                        = - 1.5°F

Then, again the temperature increased by 7.2°F from noon till 3 pm.

So, the final tempertaure at 3 pm = - 1.5°F + 7.2°F

                                                        =  5.7°F

Then, again the temperature by dropped 15.5°F from 3 pm to 6 pm.

So, the final tempertaure at 6 pm = 5.7°F - 15.5°F

                                                        = - 9.8°F

The no. of sales made by the agent if he calls 20 clients is 43.

The basic equation used to represent and solve for an unknown quantity is a linear equation in one variable. It is always a straight line and can be represented graphically. A linear equation is a straightforward way of representing a mathematical statement. Unknown quantities can be represented by any variable or symbol, but in most cases, in a linear equation with one variable, a variable 'x' is used to represent the unknown quantity.

No. of sales =18.9476+1.1842x

Here x = no. of phone calls

The agent calls 20 client.

So, x = 20

Put x = 20 in the given no. of sales. equation

No. of sales = 18.9476 + (1.1842)(20)

No. of sales = 18.9476+23.684

No. of sales = 42.6316

Since the number of sales can't be in decimal numbers, so we will round off the given no. of sales.
