Given s = 2.4 b = -7.2 t = 4.8 n = -9.6, evaluate this mathematical expression (s - b)(n + t).
These are the answer options:
23.04

-23.04

46.08

-46.08

Answers

Answer 1

Answer: Fourth Choice. -46.08

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Given information

s = 2.4

b=-7.2

t=4.8

n=-9.6

Given expression

(s - b) (n + t)

Substitute values into the expression

= (2.4 - (-7.2)) (-9.6 + 4.8)

Simplify values in the parentheses

= (2.4 + 7.2) (-4.8)

=(9.6) (-4.8)

Simplify by multiplication

= [tex]\boxed{-46.08}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

Answer 2

Answer:

- 46.08

Step-by-step explanation:

Given Values :-

s = 2.4

b = - 7.2

t = 4.8

n = - 9.6

Substituting the given values in the equation :-

= > ( s - b ) ( n + t )

= > ( 2.4 - ( - 7.2 ) ) ( - 9.6 + 4.8 )

= > ( 2.4 + 7.2 ) ( -4.8 )

= > ( 9.6 ) ( - 4.8 )

= > - 46.8

Hope it helps you ツ

There are 2 answers because it is absolute value.

It can't be 10, so the only other option is -6.

Jonathon has a collection of coins worth a total of $10.75. If he has one-fourth as many dimes as pennies, and two-thirds as many dimes as nickels, how many of each coin does Jonathon have?

Answers

The number of dimes, pennies and nickels are required.

The number of dimes is 50, pennies is 200 and nickels is 75.

Let the number of dimes be [tex]x[/tex]

From the question the number of dimes is one-fourth the number of pennies and two-thirds the number of nickels.

So,

The number of pennies is [tex]4x[/tex]

and number of nickels is [tex]\dfrac{3}{2}x[/tex]

1 nickel = 0.05$

1 penny = 0.01$

1 dime = 0.01$

Total value of the coins is $10.75

[tex]0.1x+0.05\times \dfrac{3}{2}x+0.01\times 4x=10.75\\\Rightarrow 0.215x=10.75\\\Rightarrow x=\dfrac{10.75}{0.215}\\\Rightarrow x=50[/tex]

The number of dimes is 50.

The number of pennies is [tex]4x=4\times50=200[/tex]

The number of nickels is [tex]\dfrac{3}{2}x=\dfrac{3}{2}\times50=75[/tex].

The sum of four consecutive integers is 390. Find the integers (Please show your work)

Answers

Answer:

The integers are 96, 97, 98, and 99

Step-by-step explanation:

first integer = x

second integer = x+1

third integer = x+2

fourth integer = x+3

(that what consecutive means, like 4, 5, 6, 7 are just adding 1 more each time

The sum (add them all up) is (=) 390 so

x+(x+1)+(x+2)+(x+3) = 390

4x+6=390

4x+6-6=390-6

4x=384

4x/4=384/4

x=96

x+1=97

x+2=98

x+3=99

The integers are 96, 97, 98, and 99

Damon skateboards from his house to school 4 miles away. It takes him 20 minutes to get to school.


How many minutes will it take Damon to skateboard to his friend Stefan's house, which is 2 1/2 miles from school, if he travels at the same rate that he did from his house to school.

Answers

Answer:

about 12 1/2 minutes

each mile he went to school took him 5 minutes and if his friend's house is 2 1/2 miles away then 2.5x5= 12.5

Answer:  12.5 minutes

======================================================

Work Shown:

20 min = 20/60 = 1/3 of an hour

distance = rate*time

d = r*t

4 mi = (x mph)*(1/3 hr)

4 = x*(1/3)

4*3 = x

x = 12 mph

Damon's speed is 12 mph

--------------

Now calculate the time it takes go travel to his friends house.

d = r*t

2.5 = 12*t

t = (2.5)/12

t = 25/120

t = (5*5)/(5*24)

t = 5/24

He takes 5/24 of an hour to go from school to Stefan's house.

Multiply by 60 to convert to minutes

(5/24)*60 = 12.5 minutes

Q1.) 5929 students are sitting in an auditorium in such a manner that there as are many students in a row as there are rows in the auditorium. How many rowsare there in the auditorium?​

Answers

Answer:

77 rows

Explanation:

As per the provided information in the given question, we have :

Total number of students sitting in the auditorium = 5929 studentsThere are as many students in a row as there are rows in the auditorium.

We've been asked to calculate the number of rows in the auditorium.

Let us suppose the the number of rows be x. Then, the number of number of students in each row becomes x as there are as many students in a row as there are rows in the auditorium.

Now, we have to simply frame a linear equation to tackle this question. Total number of the students will be equal to the product of number of students in each row and the number of rows.

Writing it in the form of a linear equation,

[tex] \longrightarrow \sf{\quad {5929 = x \times x}} \\ [/tex]

As there are 5929 students sitting in the auditorium.

[tex] \longrightarrow \sf{\quad {5929 = x^2}} \\ [/tex]

Now, put the square root symbol on both sides.

[tex] \longrightarrow \sf{\quad {\sqrt{5929} = \sqrt{x^2}}} \\ [/tex]

Square root of x² is x since x × x is x².

[tex] \longrightarrow \sf{\quad {\sqrt{5929} = x }} \\ [/tex]

Now, we have to find the value of √5929. By prime factorisation, 5929 = 7 × 7 × 11 × 11, make the pairs of the common factors and their product will be the square root of 5929 that is √5929 = 7 × 11 = 77.

[tex] \longrightarrow \quad\underline{\boxed{ \pmb{\frak{77 = x}} }} \\ [/tex]

Therefore, there are 77 rows in the auditorium.

Answers

Answer:

x = 10

Step-by-step explanation:

1. Because this is a right angle (an angle with 90°), 54 + 3x + 6 = 90.

2. (Solving equation above)

Step 1: Simplify both sides of the equation.

[tex](3x)+(54+6)=90[/tex] [tex]3x + 60 = 90[/tex]

Step 2: Subtract 60 from both sides.

[tex]3x + 60 - 60 = 90 - 60[/tex] [tex]3x = 30[/tex]

Step 3: Divide both sides by 3.

[tex]\frac{3x}{3} =\frac{30}{3}[/tex] [tex]x = 10[/tex]

Step 4: Check if solution is correct.

[tex]54 + 3(10)+6=90[/tex] [tex]54+30+6=90[/tex] [tex]84+6=90[/tex] [tex]90=90[/tex]

Therefore, x = 10.

Write the equation of a line perpendicular to the line 2x + 3y = 12 and passes through (9, -2). (fractions go in one box - use lower case letters)

Answers

Answer:

Step-by-step explanation:

Write the equation of the line perpendicular to 2x-3y=12 that passes through the point (16,-7)

 

Rewrite the equation as  y = (2/3)x - 4  This has slope 2/3

 

A perpendicular line will have slope -3/2 so the equation of a perpendicuar line is y = -(3/2)x + c where c is a constant found from the fact that the line must go through point (16, -7).

 

-7 = -(3/2).16 + c

c = 24 - 7  

c = 17

 

Hence perpendicular line has equation  y = -(3/2)x + 17
