Answer:

in step by step

Step-by-step explanation:

so in this chart we have red, blue, green nad white

so red is 4 times more often than blue, and blue is 2 times more often than green and green is as often as white so

so red would be the most oftenblue would be second most oftengreen and white are tied for third

lets say it landed on red 16 timesif we do the math of 16/2 we get 8it landed on blue 8 timeshalve that again which is 4it landed on green 4 times and blue 4 timeswhich means out of 32 rolls we got red 16 times, blue 8 times, and green 4 times ad white 4 times

THE FORMULAE OF HEMISPHERE : V = 2/3 * π * r³

Step-by-step explanation:

Put the formulae of hemisphere,

V = 2/3 * π * r³

Put the values in the formulae,

= 2/3 × 3.14 × 9³

= 0.6666 × 3.14 × 729

= 2.09312× 729

= 1525.8m³ ans

→ value of π (pie) is 3.14

→ formulae of radius is d/2 = 18/2 = 9 in

someone pls help me with this

Answers

Answer:

Step-by-step explanation:

The volume can be found by adding the volumes of a cylinder (the upper part of the figure) and a cone (the lower part of the figure).

Volume of Cylinder: [tex]V=\pi r^2 h=\pi(3^2)(3)=27\pi\approx 84.823 \text{ cubic feet}[/tex]

Volume of Cone: The height of the cone is 3 feet (the whole figure is 6 feet tall and the cylinder uses up 3 feet of that -- 6 - 3 = 3).

[tex]V=\frac{1}{3}\pi r^2 h=\frac{1}{3}\pi(3^2)(3)=9\pi\approx 28.274[/tex]

The total volume is 84.823 + 28.274, about 113.1 cubic feet

Diameter of the bowl is 10 inches.how many cups of water this bowl can hold? One cup is equivalent to proximatly 12.5 cubic inches

Answers

Answer:

Number of cup used for fill bowl = 20 cups (Approx.)

Step-by-step explanation:

Given:

Diameter of hemisphere bowl = 10 inches

Volume of each cup = 12.5 cubic inches

Find:

Number of cup used for fill bowl

Computation:

Radius of hemisphere bowl = Diameter of hemisphere bowl / 2

Radius of hemisphere bowl = 10 / 2

Radius of hemisphere bowl = 5 inches

Volume of hemisphere bowl = (2/3)(π)(r³)

Volume of hemisphere bowl = (2/3)(22/7)(5³)

Volume of hemisphere bowl = (2)(125)

Volume of hemisphere bowl = 250

Number of cup used for fill bowl = Volume of hemisphere bowl / Volume of each cup

Number of cup used for fill bowl = 250 / 12.5

Number of cup used for fill bowl = 20 cups (Approx.)

Θ is in Quadrant III and cos^2 Θ= 1/4

In two or more sentences, explain how to find the value of cotθ.

Answers

Answer:

Step-by-step explanation:

since cos ^2 = 1/4 then cos = 1/2

b/c cot is tan inverted, then cot = cos / sin

so we also know that [tex]\sqrt{3}[/tex]/2 will be sin for this same Ф

then

cot = (1/2) / ( [tex]\sqrt{3}[/tex]/2 )

cot = 1 / [tex]\sqrt{3}[/tex]

since Ф is in quad III

we know both parts of the fraction will be negative

cot = -1 / -[tex]\sqrt{3}[/tex]

but we would normally write that as a positive

Inscribed angles math lib
Need help with 9 and 10 thank you!!

Answers

Answer:

54° and 110°

Step-by-step explanation:

The opposite angles of a cyclic quadrilateral are supplementary, sum to 180°

(9)

19x - 26 + 7x - 2 = 180

26x - 28 = 180 ( add 28 to both sides )

26x = 208 ( divide both sides by 26 )

x = 8

Then

∠ EFG = 7x - 2 = 7(8) - 2 = 56 - 2 = 54°

(10)

21x - 33 + 14x + 3 = 180

35x - 30 = 180 ( add 30 to both sides )

35x = 210 ( divide both sides by 35 )

x = 6

Then

∠ YVW = 14x + 3 = 14(6) + 3 = 84 + 3 = 87°

The inscribed angle YVW is half the measure of its intercepted arc YW, so

arc YW = 2 × 87° = 174°, then

arc XW = 174° - 64° = 110°

Cyclic quadrilateral is drawn inside a circle. The measure of the ∠EFG is 54°. The measure of the angle made by the arc XW is 110°.

What is a Cyclic quadrilateral?

A cyclic quadrilateral is a quadrilateral that is drawn inside a circle. The sum of the opposite angle of the cyclic quadrilateral is always equal to 180°.

9.) As we know that the sum of the opposite angles of a cyclic quadrilateral is supplementary, therefore, their sum is 180°. Thus, we can write for

[tex]\angle GDE + \angle EFG = 180^o\\\\19x - 26 + 7x - 2 = 180\\\\26x - 28 = 180\\\\26x = 208\\\\x = 8[/tex]

Now, substitute the value of x, in order to get the measure of the ∠EFG,

[tex]\angle EFG = 7x - 2\\\\\angle EFG = 7(8) - 2\\\\\angle EFG = 56 - 2\\\\\angle EFG = 54^o[/tex]

The measure of the ∠EFG is 54°.

10.) As we know that the sum of the opposite angles of a cyclic quadrilateral is supplementary, therefore, their sum is 180°. Thus, we can write for

[tex]\angle YXW + \angle YVW = 180^o\\\\21x - 33 + 14x + 3 = 180\\\\35x - 30 = 180\\\\35x = 210\\\\x = 6[/tex]

Now, substitute the value of x, in order to get the measure of the ∠YVW,

[tex]\angle YVW = 14x + 3\\\\\angle YVW = 14(6) + 3 \\\\\angle YVW= 84 + 3 \\\\\angle YVW = 87^o[/tex]

As we know that in the inscribed∠YVW, the ∠YVW is half the measure of its intercepted arc YW, therefore, We can write it as,

arc YW = 2 × 87° = 174°, and

arc XW = 174° - 64° = 110°

The measure of the angle made by the arc XW is 110°.
