Answer:

Diameter of the circle is 8.4 units

Step-by-step explanation:

To find the diameter of a circle with area of 56 square units, we will follow the steps below:

write the formula for calculating the area of a circle

area of a circle = πr²

from the question area= 56 units .

π is a constant which is ≈ 3.14

we can now proceed to substitute the values into the formula and solve for r

area of a circle = πr²

56 = 3.14×r²

divide both-side of the equation by 3.14

17.83 = r²

take the square root of both-side

√17.83 = √r²

4.2 =r

r= 4.2 units

but diameter = 2 r

diameter = 2×4.2

diameter = 8.4 units

Diameter of the circle is 8.4 units

Answer:

92 ft  

Step-by-step explanation:

Assume the garden has the shape shown below.

The length of fencing equals the distance around three sides of the rectangle plus that around the semicircle.

1. Around the rectangle

Distance = 28 ft + 14 ft + 28 ft = 70 ft

2. Around the semicircle

For a circle.

C = 2πr

For the semicircle,

½C =½(2πr) = πr  

D = 14 ft, so

r =    7 ft

[tex]\text{Distance} = \dfrac{22}{7} \times \text{7 ft} = \text{22 ft}[/tex]

3. Total distance

Distance = 70 ft + 22 ft = 92 ft

Jordan will need 92 ft of fencing.

Answer:

1.88 = ?

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adjacent / hypotenuse

cos 20 = ?/ 2

Multiply each side by 2

2 cos 20 = ?

1.879385242 = ?

To the nearest hundredth

1.88 = ?

Given Information:

Volume of candle = V = 75 in³

Height of candle = h = 6 in

Required Information:

Radius of candle = r = ?

Answer:

Radius of candle = r = 2 in

Step-by-step explanation:

Recall that the volume of a cylindrical shape is given by

[tex]V = \pi \times r^{2} \times h[/tex]

Where V is the volume, r is the radius and h is the height

Re-arrange the above equation for radius

[tex]r^{2} = \frac{V}{\pi \times h} \\\\r = \sqrt{\frac{V}{\pi \times h}}[/tex]

Now substitute the given values into the above equation

[tex]r = \sqrt{\frac{75}{\pi \times 6}}\\\\r = 1.99 \: in[/tex]

Rounding to the nearest inch

[tex]r = 2 \: in[/tex]

Therefore, the radius of this candle is 2 inches.

You can compute the slope of a line by using the slope formula. This is given by:

slope,m=(change in y-axis)/(change in x-axis)

           =(Δ y-axis)/(Δ x-axis)

Given the points (x1,y1) and (x,y) from a linear graph, then:

slope m will be:

          m=(y-y1)/(x-x1)

You can compute the slope of a line by using the slope formula.

Answer:

AE = 43.2 units

Step-by-step explanation:

As per the given question image, it can be seen that in the [tex]\triangle ADC \text { and }\triangle AEB :[/tex]

1. [tex]\angle B = \angle C = 90^\circ[/tex]

2. [tex]\angle A[/tex] is common to both the triangles.

3. Two angles are common, so the third angle [tex]\angle E[/tex] is also equal to [tex]\angle D[/tex].

All the three angles in the [tex]\triangle ADC \text { and }\triangle AEB[/tex] are equal to each other, hence the triangles are similar.

As per the property of similar triangles, the ratio of their sides will be equal.

AB : AC = AE : AD

AC = 88 units

BC = 55 units

AB = AC - AB = 33 units

Let side AE = [tex]x[/tex] units

Side AD = AE + ED

So, AD = [tex]x + 72[/tex]

Using the ratio:

[tex]\dfrac{AB}{AC} = \dfrac{AE}{AD}\\\Rightarrow \dfrac{33}{55} = \dfrac{x}{x+72}\\\Rightarrow 55x = 33 \times 72\\\Rightarrow x = \dfrac{3\times 72}{5}\\\Rightarrow x = 43.2\ units[/tex]

So, AE = 43.2 units

Answer:

0

Step-by-step explanation:

Given a polynomial p(x) divided by (x + h), then the remainder is

p(- h)

Here divisor is (x + 1), so evaluate p(- 1) for remainder

p(- 1) = [tex](-1)^{5}[/tex] + [tex](-1)^{4}[/tex] + (- 1)³ + (- 1)² + 2(- 1) + 2

        = - 1 + 1 - 1 + 1 - 2 + 2

        = 0

This means that (x + 1) is a factor of p(x)

Step-by-step explanation:

i just did the test on edge 2020 and got it right

you have two walls that are  10 by 7.5 so 75 feet ^2 in area each

you have another two walls that are 14 by 7.5  so 105 feet^ 2 each

so all of that together is 360 feet^2 to cover for one coating, so you have 720 feet^2 to cover for 2 coats on the walls. so take that and divide it by the area that one gallon would cover, then round up giving you how many gallons you would have to buy

for the ceiling you do the same, the area is 140 and you only need one coat

Step-by-step explanation:

In this graph, the x value represents the count of the terms, while the y represents the value of each term. This means that the value of the first one is 2, the value of the second one is -2, the third one -6, and the fourth one -10. Hope this helps!

Answer:

(16)^3 = (7 + 9)^3 = 7^3 + 9^3 + 3 x 7^2 x 9 + 3 x 9^2 x 7

=>(16)^3 + (-7)^3 + (-9)^3 = (-7)^3 + (-9)^3 + 7^3 + 9^3 + 3 x 7^2 x 9 + 3 x 9^2 x 7

                                    =  [(-7)^3 + 7^3] + [9^3 + (-9)^3] + 3 x 7^2 x 9 + 3x9^2x7

                                    =  0 + 0 + 3 x 7^2 x 9 + 3 x 9^2 x 7

                                    = 3 x 7^2 x 9 + 3 x 9^2 x 7

                                    = 3 x 9 x 7 x (7 + 9)

                                    = 3 x 7 x 9 x 16

                                    = 3 x 7 x 9 x 8 x 2

                                    = 6 x 7 x 8 x 9

                                    = 3024

Answer:

The building is 13.91 m tall

Step-by-step explanation:

The parameters given are;

Angle of elevation to the top of the building = 71°

Angle of depression to the bottom of the building = 26°

Height of the man = 2  m

Therefore, the sight of the man, the man's height, and the distance of the man from the building forms a triangle where:

The hypotenuse side = The sight of the man to the bottom of the building

Hence;

In ΔABC, A being at the eye level or head level of the man, B at the foot and C at the bottom of the building

∴ ∠A + Angle of depression to the bottom of the building = 90°

∠A = 90° - 26° = 64°

∠B = 90° and ∠C = 26° (Sum of angles in a triangle)

[tex]Tan(C) = \frac{AB}{BC}[/tex]

Distance of the man from the building = BC

[tex]Tan(26) = \frac{2}{BC}[/tex]

[tex]BC= \frac{2}{ Tan(26) } = 4.1 \, m[/tex]

Given that the angle of elevation to the top of the building = 71°, we have;

ΔAET

Where:

A is at the head level of the man,

E is the point on the building directing facing the man and

T is the top of the building

Hence AE = BC and ∡TAE = 71°

TE + AB= The height of the building

[tex]Tan(TAE) = \dfrac{TE}{AE}\\\\Tan(71) = \dfrac{TE}{4.1}[/tex]

∴ TE = tan(71°) × 4.1 = 11.91 m

Hence the height of the building = 11.91 + 2 = 13.91 m.

Answer:

D. d^2 - πd^2/4.

Step-by-step explanation:

The sides of the square are equal to the diameter of the circles so the area of the square = d^2.

The shaded area = area of the square -  4 * the area of a quarter circle

= area of the square - area of 1 circle

= d^2 - π r^2

r = d/2 so

Area of the shaded part = d^2 -  π (d/2)^2

= d^2 -  π (d^2/4)

Answer: 9

Step-by-step explanation:

The reason for this answer, is because when you decide 18 by 6 it gives you 3. Which means that when you devide 27 by 3 it will give you your answer. 9. You can make sure it’s correct when you do the math. 27/9=3. 18/6=3.

This way, your answers are equivalent to each other.
