What is the diameter if the radius is 6ft?

Answer:

width=x, length = y

(in ft)

3x + 2y = 6y>x

y = 1.5 , x= 1

1ft = 12 in 1.5ft = 18in

Answer:

6.32 cm

Step-by-step explanation:

Area of a circle = [tex]\pi r^2[/tex]   (where r is the radius)

Given area = [tex]10\pi[/tex] cm²

⇒ [tex]10\pi=\pi r^2[/tex]

[tex]\implies 10=r^2[/tex]

[tex]\implies r=\sqrt{10}[/tex]

Diameter = 2r    (where r is the radius)

[tex]\implies d=2r=2\sqrt{10}=6.32[/tex] cm (nearest hundredth)

Area of a circle = [tex]πr²[/tex]

Given area = [tex]10π cm²[/tex]

[tex]\bold\red{ ⇒} 10π = πr²[/tex]

[tex]\bold\red{⇒ } 10 = r²[/tex]

[tex]\bold\red{⇒ } r = \sqrt{10}[/tex]

Diameter = [tex]2r[/tex]

[tex]\bold\red{⇒}2\sqrt{10} =\bold\pink{6.32 cm} [/tex] [tex]\bold\green{ [nearest \: hundredth]}[/tex]

Answer:

If youre asking how long it will take for Yoshi to catch up look below

Step-by-step explanation:

Yoshi walk 80 feet per minute faster than Trisha

If Trisha walks for 5 minutes she would have walked 2250 feet

If Yoshi also walks for 5 minutes he would have walked 2150 feet

Now this is already pretty close so lets check for 7 minutes

If Trisha walks 7 minutes she would have walked 2950 feet

if Yoshi walks 7 minutes he would have walked he would have walked 3010 feet

Now this is really close but now yoshi is ahead.. so lets go down to 6.85 feet

If Yoshi walks 6.85 minutes he would have walked 2945.5 feet

this is still a LITTLE to low so lets do 6.86

If yoshi walks 6.86 minutes he would have walked 2949.8

Rounding up he would have caught up by now

so it would take Yoshi 6.86 minutes to catch up

The value of the numerator of the calculation of the variance is 258, the correct option is D.

Given

The test scores of a geometry class are given below. 90, 75, 72, 88, 85.

Variance is the expected value of the squared variation of a random variable from its mean value, in probability and statistics.

The mean of the test scores of a geometry class is;

[tex]\rm Mean = \dfrac{90+75+72+88+85}{5}\\\\ Mean =\dfrac{ 410}{5}\\\\Mean =82[/tex]

The variance is given by;

[tex]\rm Variance =\dfrac{(90 - 82)^2 + (75 - 82)^2 + (72 - 82)^2 + (88 - 82)^2 + (85 - 82)^2}{5}\\\\Variance = \dfrac{8^2+7^2+(-10)^2+6^2+3^2}{5}\\\\Variance=\dfrac{64+49+100+36+9}{5}\\\\Variance = \dfrac{258}{5}[/tex]

Hence, the value of the numerator of the calculation of the variance is 258.

Answer:

26.7

Step-by-step explanation:

This is the answer because 26.7/20 = (16+26.7)/32

When two triangles are similar, it means their sides are also proportional. The reason why it is not ten is because you need to add 10 to 16 to the large triangle as well, which no longer makes it proportional.

To solve, you create a formula.

(16+x)/32=x/20

Multiply both sides by 32 to get rid of the 32 in the left side.

16+x=32x/20

Multiply both sides by 20 to get rid of the 20 right side.

320+20x=32x

-20x on both sides to get all the variables on one side and all the nukbers on the other.

320=12x

Divide both sides by 12 to get x by itself

x=26.66667

Answer:

Step-by-step explanation:

rise / run is another way of expressing the tangent.

So when you are told that the rise over run is 35% you mean the rise is 35% of the run.

Another way of expressing this is by saying Tan(theta) = 0.35

theta = tan-1(0.35)

theta = 19.29 degrees.

The answer is A. You can reason this out. 19 degrees is the smallest answer. If it was any larger, do you think an 18 wheeler would be able to make the grade? Likely not.

Answer:

4

Step-by-step explanation:

We can use the y-y/x-x formula.

We need to find two points that are a whole number.

(0,10) -- 0 is the x coordinate, 10 is the y coordinate.

(20,90) -- 20 is the x coordinate, 90 is the y coordinate.

10-90 = -80

0-20 = -20

-80/-20 as a whole number is 4.

The slope is 4.

The arc is the product of the angle and radius of the circle. Then the arc length is 7.065 cm.

It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The central angle of π/2 radians in a circle with a radius of 4.5 cm.

The arc is given as the product of the angle and radius of the circle.

[tex]\rm Arc \ length = Angle * Radius\\\\\\Arc \ length = \dfrac{\pi}{2} * 4.5\\\\\\Arc \ length = \dfrac{3.14}{2} * 4.5\\\\\\Arc \ length = 7.065[/tex]

The arc length is 7.065 cm.

Answer:

When rotating any polygon 90 degrees, each vertice/point of the polygon should be changed from (x, y) to (y, -x). Because of this, E(-7, -4) should be E'(-4, 7), F(-2, -1) should be F'(-1, 2), and G(-5, -8) should be G'(-8, 5) after the rotation.

Step-by-step explanation:

Like I explained above, when rotating a shape 90 degrees clockwise on a plane, the points change from (x, y) to (y, -x). The student changed each point from (x, y) to (-y, x), which is a 90 degree counterclockwise rotation. That is why the student is incorrect.

I hoped this helped! Sorry, I am terrible at explaining things. :)
