Nina likes to tip restaurant staff 18% when she enjoys the meal and has good service. Which expression represents the amount of tip, in dollars, that Nina will give when she has a positive experience eating a meal that cost n dollars? 0.18n 18n StartFraction n over 18 EndFraction n + 0.18

Answer:

8%

Step-by-step explanation:

new length = 110% x 30 = 33cm

new width = 105% x 20 = 21cm

new perimeter = 2(33 + 21) = 108cm

old perimeter = 2(30 + 20) = 100cm

percentage increase = 8/100 x 100% = 8%

C) 2x - 1

Step-by-step explanation:

12x² - 4x - 1 =  12x² - 6x + 2x - 1

                   = 6x(2x - 1) + (2x - 1)

                   = (2x - 1) (6x + 1)

Answer:

f(x) = 3x^2 - 15x + 12

Step-by-step explanation:

All of the second degree polynomials listed have a leading coefficient of 3.

Since we are asked which has roots 4 and 1, we know we need to find the polynomial where x is a negative number, then solve for x.

f(x) = 3x^2 - 15x + 12

= 3(x^2 - 5x + 4)  --- Here, I factored out the 3.

= 3((x-4)(x-1)) --- solve for the quadratic.

Therefore, solving for x, we have

x - 4 = 0    and  x - 1 = 0

x = 4                  x = 1

Thus, this polynomial has a lead coefficient of 3 and its roots are 4 and 1.

f(x) = 3x^2 - 15x + 12

This question is incomplete, the complete question is;

You have two strains of mice, one is inbred and the other is genetically heterogeneous. You examine weight differences for the mice when they are raised in the same environment. If the total variance for the inbred strain is 0.5 square ounces and total variance for the heterogeneous strain is 0.7 square ounces, what is the relative amount of variance due to genetic variation ?

Multiple Choice

A. 0.2 square ounces

B. 0.5 square ounces

C. 0.7 square ounces

D. 1.2 square ounces

Answer:

Option  A) 0.2 square ounces  is the correct answer

Step-by-step explanation:

Given that;

two strains of mice where raised in the environment and while one is inbred, the other is genetically heterogeneous.

The total variance for the inbred strain =  0.5 square ounces

total variance for the heterogeneous strain = 0.7 square ounces

relative amount of variance due to genetic variation = ?

The relative amount of variance due to genetic variation can be gotten by taking the difference of the total variance of both mice

so;

relative amount of variance due to genetic variation = variance for the heterogeneous strain - total variance for the inbred strain

we substitute our values

relative amount of variance due to genetic variation = 0.7 - 0.5

relative amount of variance due to genetic variation = 0.2 square ounces.

Therefore Option  A) 0.2 square ounces  is the correct answer

Answer:

g(2) = 12

Step-by-step explanation:

g(x) = 2x³ – 4; g(2)

g(2) = 2(2)³ – 4

= 2 × 8 – 4

= 16 – 4

g(2) = 12

Thus, The answer is g(2) = 12

Answer:

The measure of ∠A = 58.0°

Step-by-step explanation:

we will use the trigonometry function "tan" to solve the question

∵ BC is the opposite side of ∠A

∵ AC is the adjacent side of ∠A

∵ tan A = [tex]\frac{opposite}{adjacent}[/tex]

∴ tan A = [tex]\frac{BC}{AC}[/tex]

∵ BC = 8 units

∵ AC = 5 units

∴ tan A = [tex]\frac{8}{5}[/tex]

→ Use the inverse function of tan to find the measure of angle A

∵ m∠A = [tex]tan^{-1}(\frac{8}{5})[/tex]

∴ m∠A = 57.99461679°

→ Round it to the nearest tenth

∴ m∠A = 58.0°

∴ The measure of ∠A = 58.0°

Answer:

4

Step-by-step explanation:

First you need to figure out how many numbers can create a 0 at the end. Of course 10, and 20 can. Next, 2*5 and 12*15 can also do that. This means you will have 4 zeros at the end. Or you can simply use a calculator!

N = 1 × 2 × 3 × 4 × ... × 20  will give four terminal zeros.

To do such question there are 2 methods, conventional and non-conventional approach.

Conventional Approach;

N = 1 × 2 × 3 × 4 × ... × 20

Non-conventional approach;

To form a zero at the end of a number, we need to multiply it with a multiple of such 10, 20, 30, etc.

Also, a multiplication of 5 and 2 gives as zero.

Therefore, numbers (5 x 2), 10, (12 x 15), and 20, will give us four terminal zeros.

hence, N = 1 × 2 × 3 × 4 × ... × 20  will give four terminal zeros.

So first, b is the y intercept, where the line intercepts the y axis. So, put a dot at -3. After that, do the slope. Rise over run. So, go down 3 (because negative) and to the right 2. Then, put a line through the dots and you'll have your graph. If you need me to graph just ask.
