Some people can roll their tongue into a tube shape, while other cannot. Practicing is not likely to help because tongue-rolling is an inherited trait. The allele for rolling the tongue (R) is dominant to the allele for not being able to roll the tongue (r). Look at the Punnett square. It shows a cross between two parents with at least one R allele. Complete the Punnett square above by identifying the correct locations (letter) for each allele and genotype (pair of alleles).

              = 353.25 + 380.55

              = 733.80

∴The restaurant manager's profit in dollars is $733.80.

Answer:

[tex]\Huge\boxed{x=42}[/tex]

Step-by-step explanation:

Hello There!

The shown angles are supplementary angles.

We know this because a straight line is split into two angles

A straight line creates a 180 degree angle so the sum of the two angles is 180

So we can use this equation to solve for x

180 = 3x + 12 + x

3x + x = 4x

180=4x+12

step 1 subtract 12 from each side

180-12=168

12-12 cancels out

now we have

168=4x

step 2 divide each side by 4

4x/4=x

168/4=42

we're left with x = 42

Simplify −3√27−2√2−3√45−√18 Work Needed

Answers

Answer:

Step-by-step explanation:

27 = 3 * 3 * 3

-3√27 = -3*3√3 = -9√3

Index of the radical is 2. So, after prime factoring, for each two of same number, pull one outside.

-3√45= -3√3*3*5 = -3*3√5 = -9√5

-√18 = -√2*3*3 = -3√2

-3√27 - 2√2 - 3√45 - √18 = -9√3 - 2√2 -9√5 -3√2

Now combine like terms

         = -9√3 - 9√5 -2√2 - 3√2

        = -9√3 - 9√5 - 5√2

Answer:

-9√3 - 5√2 - 9√5

Step-by-step explanation:

-3√27 = -3√9x3 = -3x3√3 = -9√3

2√2 = 2√2

3√45 = 3√9x5 = 3x3√5 = 9√5

√18 = √9x2 = 3√2

-9√3 - 2√2 - 9√5 - 3√2 = -9√3 - 5√2 - 9√5
