I need help with #3

Answers

Answer 1

Answer: Unit rate = 3/8 : 1/6

We can also write this as:

3/8 / 1/6

Flip the 2nd fraction and multiply:

3/8 * 6/1

Multiply the numerators and denominators together:

18/8

Simplify by dividing the numerator and denominaotr by 2:

18 / 2 = 9
8 / 2 = 4

So we have:

9/4

Is a trapezoid always a polyhedron

Answers

No, a trapezoid is at least one pair of parallel sides.
A Polyhedron is a 3 dimensional shape with flat faces - Not all are parallel, therefore it is not always a trapezoid. :-)

Estimate the radius of a circle with a circumference of 92 ft. Round your answer to the nearest tenth. 29.3 ft
10.8 ft
14.6 ft
5.4 ft

Answers

Answer:

14.6 ft

Step-by-step explanation:

Hello,

thanks for leaving your query here in brainly, I think I can help you with this

te circumference of a circle is given by

$Circumference=2*\pi *radius$

Step one

solve for radius

$Circumference=2*\pi *radius\n(Circumference)/(2*\pi ) =radius\nradius=(Circumference)/(2*\pi )$

Step 2

replace

Let

Circumference=92 ft

$radius=(Circumference)/(2*\pi )\nradius=(92\ ft)/(2*\pi )\nradius=14.64\ ft\n\to\ the\ nearest\ tenth\nradius=14.6\ ft\n$

radius=14.6 ft

I hope it helps, have a fantastic day

circumference of circle = 2*pi*r=92
2*(22/7)*r=92
solving r = 92*7/44 = 14.6 ft

6 times a number is 27 less than the square of that number. Find the positive solution.

Answers

The positive solution will be "x = 3, -9". To understand the calculation check below.

Factorization

According to the question,

Let,

The number be "x".

6x = x² - 27

Now,

x² - 6x - 27 = 0

By applying factorization, we get

→ x² - 3x + 9x - 27 = 0

By taking common,

x (x - 3) + 9 (x - 3) = 0

(x + 9) (x - 3) = 0

(x + 9) = 0

x = -9

or,

(x - 3) = 0

x = 3

Thus the answer above is correct.

Find out more about factorization here:

brainly.com/question/25829061

Let x = your number.

6x = x^2 - 27. Subtract 6x from each side.

0 = x^2 - 6x - 27. Factor

0 = (x-9) (x+3). Set each term equal to zero

(x+3) = 0. Subtract 3 from each side.

x = -3. This is the negative solution.

(x-9) = 0. Add 9 to each side.

x = 9. This is the positive solution.
