Answer:

$303 0cents

Step-by-step explanation:

237 + 128 -62 = 303

The amount Julie has to spend after buying the chair is $303.

The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.

As per the given data:

We are given the details of the transactions that Julie did.

We have to find out the remaining amount of money that is left with Julie after the transactions.

Initial amount that Julie had to spend (A) = $237

Amount received as a refund after returning that calculator (B) = $128

Price that had to be paid to buy a chair (C) = $62

For finding out money in dollars and cents did Julie have to spend after buying the chair:

= A + B - C

= 237 + 128 - 62

= 365 - 62

= 303

The amount Julie has to spend after buying the chair is $303.

Hence, The amount Julie has to spend after buying the chair is $303.

Answer:

3a + (5b + 7c)

Step-by-step explanation:

The answer cannot be 3a(5b +7c) because when the number is immediately before the brackets, it signifies multiplication. therefore the 3a(5b+7c) would be equivalent to 15ab+21ac

the answer cant be 7c(5b+3a) because of the same explanation as the one above, therefore 7c(5b+3a) would be equivalent to 35cb+21ca

the answer finally cant be 8ab+7c because it means that one added 3a and 5b giving you 8 but it cannot be ab because ab is equivalent to a×b, hence, one cant put a multiplied algebraic expression with an added number

The equation equivalent to the the expression (3a + 5b) + 7c is 3a + (5b+7c). Hence, the first option is the correct one.

In mathematics, expressions are assertions that must contain at least two words with variables or terms with numbers in them, or both, and connect them with an operator. It is possible for the mathematical operators to be addition, subtraction, multiplication, or division.

For instance, the equation x + y has the terms x and y with an addition operator in between. Numerical expressions, which just contain numbers, and algebraic expressions, which also include variables, are the two types of expressions used in mathematics.

The first option is correct because it does not affect the main equation rest are not the same as the equation.

For example, let's take the second equation :

3a (5b + 7C)

After solving this option we get 15ab + 21 ac so it is incorrect because it changed the main expression.

The volume of cylinder V as a function of the height h is: V = 50.24h

In this question, we have been given the radius of the cylinder which is 4 centimeters.

We need to write the volume V of the can as a function of the height h.

We know that, the formula of volume of the cylinder of radius r and height h is, V = π × r² × h

In this question, r = 4 centimeters

Substitute r = 4 in above formula of volume of cylinder.

⇒ V = π × r² × h

⇒ V = π × 4² × h

⇒ V = 3.14 × 16 × h

⇒ V = 50.24 × h

⇒ V = 50.24h

Therefore, the volume of cylinder V as a function of the height h is:

V = 50.24h

Distance ran by Jake in a day is  17.33 miles.

It is given in the question that Jake ran 121.3 miles in a week. Also, Jake ran an equal number of miles each day.

We have to find the distance ran by him in a day.

Let the distance ran by him in a day be x miles.

We know that there are 7 days in a week.

Hence, according to the data given in the question, we can write,

Number of days in a week * distance ran in a day = total distance

Hence,

7*x = 121.3 miles

Where:

x = Number of bracelets sold or sales = 77

Total obtain the revenue, substitute x = 77 into equation (1), we have:

Revenue = f(77) = 5 * 77

Revenue = $385

Since profit is $50 less than 80% of the revenue, we have:

The value of x from the given diagram is 64 degrees

A line is defined as the shortest distance between two points. From the given diagram, we have that the line AB bisects FAB, hence;

<FAB = <CAB = 58 degrees

Also since the sum of angles on a straight line is 180 degrees, hence;

58 + 58 + x = 180

116 + x = 180

x = 180 - 116

x = 64 degrees

The coordinates of ABC are respectively (-1/3,1), (4/3,2/3), and  (0/3,5/3) .

Given a point P(x,y), its dilation about the origin by a scale factor of k maps the point to a point P'(kx,ky).

If we are given the dilated point, then we can find the original point by dividing by the scale factor.

Triangle ABC was dilated by a scale factor of 3 about the origin mapping it to triangle A'B'C' with vertices A'(-1/3), B'(4/,2), and C(0/-5).

The coordinates of triangle ABC are:

A=(-1/3,3/3) = (-1/3)

B=(4/3,2/3) = (4/3,2/3)

C=(0/3,-5/3) = (0/3,-5/3)

coordinates are formed by two components that are a latitude , giving the north-south position, and a longitude, giving the east-west position.
