B.If M ZACB = 180, And MZACD = 55, ThenmZDCB = [?]Enter

Answers

Answer 1

Answer:

125

Step-by-step explanation:

/_ ACB = 180

/_ ACD = 55

/_ ACB is made up of /_ACD and

/_ DCB

Hence, /_ ACB = /_ ACD + /_ DCB

*We then plug in the known values*

180 = 55 + /_ DCB

We now solve for the missing angle

Subtract 55 from both sides

125 = /_ DCB

What is the equation of a circle with center (7, 2) and radius 2?

Answers

Answer:

(x - 7)² + (y - 2)² = 4

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (7, 2 ) and r = 2 , then

(x - 7)² + (y - 2)² = 2² , that is

(x - 7)² + (y - 2)² = 4 ← equation of circle

Do the side lengths 7, 20 and 21 form a right triangle?

Answers

Answer: No, the side lengths do not form a right triangle.

==============================================

Work Shown:

a^2+b^2 = c^2

7^2+20^2 = 21^2

49+400 = 441

449 = 441

We end up with a false equation, so the original equation is false for those a,b,c values.

By the pythagorean theorem converse, we do not have a right triangle.

Because a^2+b^2 > c^2, this triangle is acute.

To get 3/4 miles to 1 mile we must take the reciprocal of the number and multiply it.

[tex]\frac{3}{4}[/tex]×[tex]\frac{4}{3} =1[/tex]

We need to multiply the 4 1/2 ounces by 4/3 too

[tex]4\frac{1}{2}[/tex]×[tex]\frac{4}{3} =6[/tex]

4 1/2 ounces per 3/4 miles

6 ounces per 1 mile

Answer:

6 ounces

Step-by-step explanation:

Let the unknown number be x

[tex]4 \frac{1}{2} \: \: ounces = \frac{3}{4} \: \: miles \\ x = 1 \: \: mile[/tex]

Now simply use cross multiplication to solve it

[tex]4 \frac{1}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} = \frac{3x}{4} \\ [/tex]

Now make x as the Subject

[tex] \frac{9}{2} = \frac{3x}{4} \\ \frac{9 \times 4}{2 \times 3} = x \\ \frac{36}{6} = x \\ 6 = x[/tex]

So the answer is
