Maurice receives $3 per week for allowance and earns an additional $1.75 for each chore he completes. Write an equation to find t, the total amount earned for c chores in one week.

There are 18 minutes John must have used during the month.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

A cell phone company has a basic monthly plan of 40$ plus $0.45 for any minutes uses over 700.

Before receiving this statement, John saw he was charged a total of $48.10.

Let the time he must have used during the month = x

So, We can formulate the equation as;

⇒ $48.10 = $40 + $0.45 x

Solve for x as;

⇒ 48.10 - 40 = 0.45x

⇒ 8.10 = 0.45x

⇒ x = 8.10 / 0.45

⇒ x = 18

[tex]\boxed{x=3\sqrt{3}}[/tex]

A right triangle is the one that has a 90° degree side. The hypotenuse is the largest side while the legs are the other two sides. The sketch for this problem is shown in the Figure below. To compute the other side, that is x, we must use the Pythagorean Theorem as follows:

[tex]H=\sqrt{Leg_{1}^2+Leg_{2}^2} \\ \\ \therefore H^2=Leg_{1}^2+Leg_{2}^2 \\ \\ Leg_{2}=\sqrt{H^2-Leg_{1}^2} \\ \\ x=\sqrt{14^2-13^2} \\ \\ \therefore \boxed{x=3\sqrt{3}}[/tex]

Answer:

Option D.,50 miles per hour

Step-by-step explanation:

The graph shows the distance covered by motor boat at  = y, ( in miles )

The certain amount of time on = x ( in hours )

The slope of the given line will represent the speed of the motorboat.

The given line passes through two points ( 0, 25 ) and ( 4, 225 )

Therefore, slope of the line = [tex]\frac{y-y'}{x-x'}[/tex]

                                              =  [tex]\frac{225-25}{4-0}[/tex]

                                              =   [tex]\frac{200}{4}[/tex]

                                              = 50

The speed of the motorboat is 50 miles per hour.

Final answer:

The cost of one pound of sausage is $5.69 per pound.

Explanation:

To solve the problem of finding the cost of one pound of sausage when 9 pounds cost $51.21, we use the concept of unit price. The unit price is the cost for one unit of an item when given the total cost for multiple units.

To find the unit price of the sausage, you divide the total cost by the number of pounds.

This gives you the cost per one pound of sausage, which is what we are looking for.

Here is the step by step calculation:

Therefore, one pound of the special sausage costs $5.69.

Final answer:

The correct equation to represent the total number of books Jarrod packed is B. y = 12(x - 8) + 128, which acknowledges he packed 8 boxes of science books and the remaining boxes were for math books.

Explanation:

Jarrod packed 8 boxes of science textbooks with 16 books per box, which totals to 8 × 16 = 128 books.

For the math textbooks, if x represents the total number of boxes packed, then Jarrod would have packed (x - 8) boxes of math textbooks since he already packed 8 boxes of science textbooks.

Each math textbook box contains 12 books, so the number of math books packed is 12 × (x - 8). The total number of books that Jarrod packed is the sum of both science and math books, which is given by 128 + 12 × (x - 8).

The correct equation that represents this word problem is B. y = 12(x - 8) + 128, where y is the total number of books packed and x is the total number of boxes packed.

To make 13/4 to 4 you must have to add 3/4 in the given equation.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the information given in the question,

Let the number is x.

So,

13/4 - x = 4

x = 13/4 - 4

x = (13 - 16)/4

x = -3/4

The problem statement is about the estimation of error in computation, here we will be presented with two values, the actual and the estimated value.

The present error in Irene’s measurement is 11.1%

Given data

Actual value = 40 inch

Estimate value = 45 inch

The formula for calculating the percent error is given as

Percent error = (Actual - Estimated/Estimated) *100

Percent error = (40 - 45/45) *100

Percent error = (-5/45) *100

Percent error = (-0.111) *100

Percent error = 11.1 %

Hence the percent error is 11.1%

The curve has an equation containing the variables. The rate of change of any independent variable concerning the dependent variable is entitled as the slope of the tangent to the curve. Thus, the line does not describe the slope.

Slope can be defined as the ratio of the change in the value of the dependent variable to the change in the value of an independent variable.

Let us consider the equation of a line that is y=mx+c.

Here, m is the slope of the line and the value of m is y/x.

Following are the points that may describe the slope.

A line can never be a slope because the slope is always a numeric value and a line can always be an equation that contains variables.

Answer:

b,c,e,f just did it trust me

Step-by-step explanation:

we know that

if two lines are perpendicular

then

the product of their slopes is equal to minus one

so

[tex]m1*m2=-1\\m2=-1/m1[/tex]

in this problem the slope of the given line is

[tex]m1=-0.3=-\frac{3}{10}[/tex]

the value of m2 is

[tex]m2=-1/(-3/10)=\frac{10}{3}[/tex]

with the point [tex](3,-8)[/tex] and the slope m2 find the equation of the line

the equation of the line in the form point-slope is

[tex]y-y1=m*(x-x1)[/tex]

substitute the values

[tex]y+8=\frac{10}{3}*(x-3)[/tex]

[tex]y=\frac{10}{3}x-10-8[/tex]

[tex]y=\frac{10}{3}x-18[/tex]

therefore

the answer is

[tex]y=\frac{10}{3}x-18[/tex]

The answer for this problem is 2/3

The hours of jazz are on Ivan's MP3 player, if Ivan has 4 hours of Music on his MP3 player is 2/3 or 0.7 hours.

Only verbal descriptions of a portion of the whole were used to write fractions in ancient Rome. The numerator and denominator of fractions are first written in India with one number above the other but without a line. The line used to divide the numerator and the denominator were only added by Arabs.

Given:

Ivan has 4 hours of Music on his MP3 player,

jazz makes up 1/6 of the total time,

Calculate the hours of jazz on Ivan's MP3 player as shown below,

The hours of jazz are on Ivan's MP3 player = 1 / 6 of the total time

The hours of jazz are on Ivan's MP3 player =  1 / 6 × 4 hours

The hours of jazz are on Ivan's MP3 player = 4 / 6

The hours of jazz are on Ivan's MP3 player = 2 / 3

Thus, the time of jazz is 2 / 3 or 0.7 hours.

In mathematics, the principle of rounding instructs us to look at the decimal part . If it's .5 or higher, we round up; if it's less than .5, we round down. Hence, 312.501 rounded to the nearest whole number is 313.

The question pertains to the concept of rounding numbers. In mathematics, rounding means replacing a number with an approximate value that has a shorter, simpler, or more explicit representation. To round 312.501 to the nearest whole number, we look at the decimal part of the number. If the decimal is .5 or greater, we round up; if it's less than .5, we round down. In this case, the decimal part is .501, so we round up to the next whole number.

So, 312.501 rounded to the nearest whole number is D. 313.
