4. Emily ate dinner at Geisha. Her total was $17.50. A 8% sales tax was
added to her bill. After, Emily added a 20% tip on the total after tax. What
was Emily's final total?
*

Answers

Answer: $22.68

Step-by-step explanation:

17.50 times 0.08 = 1.40

17.50 + 1.40 = 18.90

Now the tip:

18.90 times .2 = 3.78

18.90 + 3.78 = 22.68

The product of
two integers is – 24. The difference
between the two integers is 14. The sum of
the two integers is 10. What are the two
integers?

Answers

Answer:

a= 12

b=-2

Step-by-step explanation:

12 x -2 = -24

12 - (-2) = 14

12 + (-2) = 10

The two integers are 12 and -2.

What are simultaneous equation?

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Let x and y be the two integers.

So it is given that,

Product of two integers =  – 24

⇒ xy = - 24   ....(i)

The difference between the two integers =  14

⇒ x - y = 14  ...(ii)

The sum of the two integers = 10

⇒ x + y = 10     ....(iii)

Now adding equation (ii) and (iii) we get,

2x = 24

⇒ x = 12

Putting the value of x in equation (i) we get,

12y = - 24

⇒ y = - 2

So the required integers are 12 and - 2.

Find the geometric mean between 4 and 20.

Answers

Answer:

4[tex]\sqrt{5}[/tex]  

Step-by-step explanation:

Geometric mean is when you multiply the two numbers 4 and 20 and then take the square root of the product.

So 4 x 20 = 80, and the [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex]

However-- that's if you meant finding the geometric mean of 4 and 20 when you said "between"

Answer

4√5

Explanation

4 x 20 = 80

This is proportional relationship

The function is:

f(x) = 6.5xTable B

The slope is:

(10 - 7)/(4 - 3) = 3

The ABC Book Club charges a $40 monthly fee, plus $2 per book read in that month. The Easy Book Club charges a 35$ monthly fee, plus 3$ per book read in that month. For each club, how many books must be read in 1 month for the total charges from each club to be equal.

Answers

The expression for the cost of the ABC Book Club is 2x + 40. The expression for the cost of the Easy Book Club is 3x + 35. To find when the total charge for both book clubs is equal, the two expressions must equal each other. (x = the number of books read)

2x + 40 = 3x + 35

Subtract 35 from both sides.

2x + 5 = 3x

Subtract 2x from both sides.

5 = x

So, the total charge for each club is equal when 5 books are read.

What is the value of the x ? x + x + x = 56

Answers

x = 56 divided by 3 = 18.6

Hey there!

ORIGINAL EQUATION

x + x + x = 56

CONVERT/COMBINE the LIKE TERMS

1x + 1x + 1x = 56
2x + 1x = 56

NEW EQUATION

3x = 56

DIVIDE 3 to BOTH SIDES

3x/3 = 56/3


SIMPLIFY IT by canceling out 3/3 because it give you 1 & KEEP 56/3 because help solve for the x-value (it also give you the x-value result)


x = 56/3

x = 18.666667

x = 18 2/3


EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE ALL EQUIVALENT TO EACH OTHER

Fiber one bran cereal boasts that it contains 57% of the Daily Value of fiber you need. If 1 serving contains 15 gram of fiber, how much fiber do you need in one day

Answers

Answer:

26.3 grams

Step-by-step explanation:

57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)

What’s the value of a?

Answers

Answer:

a = 69

Step-by-step explanation:

The linear pair equals 180 degrees.

a + 90 + 21 = 180

a + 111 = 180

a = 69

nice!

Answer:

A= 69 degrees

Step-by-step explanation:

if all those angles equal a total of 180 degrees then all you need to do is add the angles your given which in this case is 21 and a 90 degree angle which would equal 111 degrees, then subtract 111 from 180 and that would be the answer to the missing angle, which is 69 degrees.

21 + 90 = 111

180- 111 = 69

Two streets form an intersection. C and D are supplementary
angles. If the measure of C is 140° and the measure of D is
two times the value of x, what is the value of x?

Answers

Answer:

20degrees

Step-by-step explanation:

The sum of angle C and D is 180 degrees since they are supplementary

Given

m<C = 140 degrees

m<D = 2x

Taking the sum and equating to 180

140 + 2x = 180

2x = 180-140

2x = 40

x = 40/2

x = 20 degrees

Hence the value of x is 20degrees
