What is the value of the expression shown when n = 6?

“8 less than the quotient of 42 and a number”

Answers

Answer:

8 less then the quotient of 42 and a number

a " quotient " is the result of division

(42 / n ) - 8.....when n = 6

(42/6) - 8 =

Step-by-step explanation:

Kevin has $4.85 in nickels and dimes. If he has 34 fewer dimes than nickels, how many coins (nickels and dimes) does he have altogether?

A. 74 coins

B. 75 coins

C. 76 coins

D. 77 coins

Answers

Answer:

if   x = the number of nickles   and     x-34 = the number of dimes                    then .05x + .10(x-34) = 4.85               or          .15x = 8.25               x = 55

So, nickles = x = 55

dimes = (x-34) = 21

55+ 21 = 76 So, that means your answer is C. 76 coins

Step-by-step explanation:

Answer:

the correct answer is C

Step-by-step explanation:

Set the 34 more nickels aside.

--> pairs of 1 nickel & 1 dime each worth 15 cents & a total of $3.15 ($4.85 - $1.70)

315/15 = 21 pairs

--> 21 dimes and 55 nickels

Mrs. Irvin's kids would like some sandwiches! They can choose from 3 kinds of bread, 2 types of meat, and 4 types of cheeses. How many different sandwich combinations could she make? (Hint: Draw a tree diagram to help figure out the combinations. You could label bread as B1, B2, B3; meat as M1, M2; cheese as C1, C2, C3, C4, etc)
9 sandwich combinations
10 sandwich combinations
24 sandwich combinations
None. They will all end up wanting peanut butter instead and then just feed it to the dog. ;)

Answers

Answer:

I don't knoooooooooow

Answer:

24 sandwich combinations

Step-by-step explanation:

To solve this problem, you can do 3x2x4, and you would get 24.

Or, you can do something like this:

1st kind of bread with 1st type of meat and 4 options of cheese = 4 possible combinations

1st kind of bread with 2nd type of meat and 4 options = another 4 possible combinations

Those combinations added together equals 8 combinations. If you multiply this by 3 (3 types of bread), then you would get 24 sandwich combinations, which is the answer.

Hope this helps! :)

Find the area of the trapezoid.

Answers

Answer:

A = 108 m^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2)h  where b1 and b2 are the lengths of the bases

A = 1/2(10+14) (9)

A = 1/2 (24)*9

A = 108 m^2

Answer:

108 meters squared

Step-by-step explanation:

Area = (1/2)(base 1 + base 2)*height

Area= (1/2)(14+10)*9

Area= (1/2)(24)(9)

Area= 12*9

Area= 108 meters squared

An employee works for $45 hours each week. He is paid $4 per hour for 40 hours per week and $6 per hour for overtime, what is his gross weekly wage?

Answers

Answer: $190

Step-by-step explanation:

Normal pay $4 * 40 hours = $160

Overtime $6 * 5 = $30

Answer:

Step-by-step explanation:

Gross wage = Regular wage + overtime wage

Employee works for 45 hours = 40 hours + 5 hour overtime

Gross wage = 4*40 + 6*5

                   = 160 + 30

                  = $ 190

Answers

Answer:

31.4 cm

62.8 cm

Step-by-step explanation:

The radius of the inner circle is 5 cm.  The line from the edge of the outer circle to the edge of the inner circle is 5 cm.  Assuming that the center of the outer center is the same as the center of the inner circle, the radius of the outer should be 10 cm.

Use the formula for circumference since you have the radius.

Inner circle

C = 2πr

C = 2π(5)

C = 10π

C = 31.4 cm

Outer Circle

C = 2πr

C = 2π(10)

C = 20π

C = 62.8 cm

How many minutes does it take 121212 people to paint 121212 walls?
minutes

Answers

Answer:

323232÷121212

answer=2.66

Answer:

32 minutes

Step-by-step explanation:

Imagine that each person is assigned one wall, and all 8 people begin painting at the same time.

Since everyone will finish painting their assigned wall after 32 minutes, it takes one person 32 minutes to paint one wall.

If we have 12 people and 12 walls, we can again assign one wall to each person.

Everyone will take 32 minutes to paint their assigned wall.

In other words, it takes 32 minutes for 12 people to paint 12 walls.

Answers

Answer:

see explanation

Step-by-step explanation:

13 (a)

Given

x + 2y = 3 ( subtract x from both sides )

2y = - x + 3 ( divide all terms by 2 )

y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

(b)

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2

(c)

The partial equation of the perpendicular line is

y = 2x + b

To find b substitute (1, 4) into the partial equation

4 = 2 + b ⇒ b = 4 - 2 = 2

y = 2x + 2 ← equation of perpendicular line

4a ) Difference ⇒ $ 63.24,

4b ) 4 children

Step-by-step explanation:

4a ) If the number of children is represented by the value of x, let us substitute a family of 2 children as value of x into this equation we are given;

y = 21.08 * ( 2 ) + 85.15 ⇒ Multiply 21.08 by 2,

y = 42.16 + 85.15 ⇒ Combine like terms,

y = 127.31

If y ⇒ amount spent on grocery's, let us solve for the amount spent on 5 children, and subtract from this amount;

y = 21.08 * ( 5 ) + 85.15 ⇒ Multiply 21.08 by 5,

y = 105.4 + 85.15 ⇒ Combine like terms,

y = 190.55

Difference; 190.55 - 127.31 = 63.24,

Solution; Difference ⇒ $ 63.24

4b ) If the amount is $ 169.47, let us plug it into our given equation provided amount spent on groceries ⇒ y;

169.47 = 21.08x + 85.15 ⇒ Subtract 85.15 from either side of equation,

21.08x = 84.32 ⇒ Divide either side 21.08,

x = 4 children

Solution; 4 children

Both lines have a negative slope and The slope of the line in the graph is -2

The equation of a straight line is given by:

y = mx + b;

where m is the slope of the line, b is the y intercept, y,x are variables.

Given that a line goes through (-2, 1) and (0, -3), the equation of this line is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-1=\frac{-3-1}{0-(-2)} (x-(-2))\\\\y-1=-2(x+2)\\\\y-1=-2x-4\\\\y=-2x-3[/tex]

Therefore the slope of the line in the graph is -2

The second line is given by:

[tex]y=-\frac{2}{9} x+2[/tex]

This line has a slope of -2/9

a) Both lines have a negative slope

b) The graph has a steeper slope

c) The slope of the line in the graph is -2

d) The graph and equation do not express an equivalent function because they have different equations
