Answer 2

answer:

c.962.51 in^3

step-by-step explanation:

so first we have to find the radius

in order to find the radius we divide 12 1/4÷2

which equals 6.125, now we have our radius

now we need to set up the formula

v=4/3πr^3

v=4/3π6.125^3

v=962.51

to check your work you can goo-gle volume of a sphere **you should get the same answer**

good luck :)

hopefully, this helps

have a nice day !!

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

Answer:

244 and 43

Step-by-step explanation:

hope this helps n please mark brainliest

Answer:

$733.80

Step-by-step explanation:

To calculate the profit, you use 7.85m + 8.85d

Since m = 45 and d = 43,

his profit = (7.85 × 45) + (8.85 × 43)

              = 353.25 + 380.55

              = 733.80

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

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).

Find the distance between each pair of points

Answers

Answer:

4: (0, 4)

5: (0, 8.8)

6: (0, 6)

7: (10, 0)

Step-by-step explanation:

6-2=4

5.5-(-3.3)=8.8

-7/12-(-1/2)

31/4-(-9/4)=10

The distances between the points are:

4) 45) 8.86) 67) 10How to find the distances between the points?

The distance between two points (a, b) and (c, d) is given by:

[tex]distance = \sqrt{(a - c)^2 + (b - d)^2}[/tex]

4) Here the points are (-5, 2) and (-5, 6) so the distance is:

[tex]distance =\sqrt{(-5 - (-5))^2 + (6 - 2)^2} = 4[/tex]

5) Here the points are (4.5, -3.3) and (4.5, 5.5), so the distance is:

[tex]distance = \sqrt{(4.5 - 4.5)^2 + (-3.3 - 5.5)^2 } = 8.8[/tex]

6) Here the points are (5 + 1/2, -7 - 1/2) and (5 + 1/2, -1 - 1/2), so the distance is:

[tex]distance = \sqrt{(5.5 - 5.5)^2 + (-7.5 - (-1.5)^2)} = 6[/tex]

7) Here the points are (-2.25, -8) and (7.75, -8), so the distance is:

[tex]distance = \sqrt{(-2.25 - 7.75)^2 + (-8 + 8)^2} = 10[/tex]
