Geometry B: fill in the blank

Mathematics
1 answer:
olga_2 [115]2 years ago
3 0

Answer:

The circumference of a circle is the distance around the entire circle, while arc length, s, is the distance <u>between</u> two points on the circle.

C = 2πr = 2π( <u>5</u><u> </u>) = 10π ≈ 31.4 units

3.14 is an approximation for π.

s = θ/360° (C)

mAB = 60°/360° ( 31.4)

= <u>1</u><u>/</u><u>6</u>(31.4) ≈5.2 units

Jessica is a custodian at Oracle Arena. She waxes 20 \text{ m}^220 m 2 20, space, m, start superscript, 2, end superscript of th
Evgesh-ka [11]

Given that Jessica is a custodian at Oracle Arena.

She waxes 20 square meters space of the floor in 5/3 of an hour. Jessica waxes the floor at a constant rate means rate will remain fixed for any hour.

Now we have to find about how many square meters can she wax per hour.

To find that we just need to divide 20 squaer meters by 5/3 hours

\frac{20}{\left(\frac{5}{3}\right)}

=20\cdot\frac{3}{5}

=\frac{60}{5}

=12

Hence final answer is 12 square meters can she wax per hour.

Which can also be written as 12m^2 per hour.

How can you use a right angle to decide how to name another angle
blondinia [14]
You can see if the other angles add up to 180 or 360 degrees (depending on shape) then add them to make it the number, for example, if a triangle has a right angle, then the other 2 angles are 45 degrees, knowing that EVERY triangle's angles add up to 180 degrees.

the solutions to the inequality y &gt; −3x 2 are shaded on the graph. which point is a solution? a). (0, 2) b). (2, 0) c). (1, −
PolarNik [594]

we have

y> -3x+2

The solution is the shaded area above the dotted line

we know that

If a point is a solution of the inequality, then the coordinates of the point must satisfy the inequality

We will verify all cases to determine the solution of the problem

<u>Case A)</u> Point (0,2)

x=0\\y=2

Substitute the value of x and y in the inequality and verify

2> -3*0+2

2>2 -------> is not true

therefore

the point (0,2) is not a solution of the inequality

<u>Case B)</u> Point (2,0)

x=2\\y=0

Substitute the value of x and y in the inequality and verify

0> -3*2+2

0>-4 -------> is true

therefore

the point (2,0) is a solution of the inequality

<u>Case C)</u> Point (1,-2)

x=1\\y=-2

Substitute the value of x and y in the inequality and verify

-2> -3*1+2

-2>-1 -------> is not true

therefore

the point  (1,-2) is not a solution of the inequality

<u>Case D)</u> Point (-2,1)

x=-2\\y=1

Substitute the value of x and y in the inequality and verify

1> -3*(-2)+2

1>8 -------> is not true

therefore

the point (-2,1) is not a solution of the inequality

therefore

<u>the answer is the Point B</u>

(2,0)
