PLEASE HELP WITH GEOMETRY QUESTION!! WILL GIVE BRAIN SHOW WORK!!!

Answers

Answer:

140.6 ft³

Step-by-step explanation:

The volume remaining is calculated as

V = volume of block - volume of cylinder

   = s³ - πr²h ( s is side of block, r is radius, h is height )

Here s = 6, r = 4 ÷ 2 = 2, h = 6 , then

V = 6³ - (π × 2² × 6)

   = 216 - (π × 4 × 6)

   = 216 - 24π

   ≈ 140.6 ft² ( to the nearest tenth )

Which of the following correctly gives the center and radius of the circle defined by (2 -
- 7) + (y - 2)2 = 10?
O Center: (7, 2); Radius = 100
O Center: (7, 2); Radius - V10
O Center:(-7, - 2); Radius = 100
O Center:(-7, -2); Radius = 10

Answers

Answer:

Center = (7, 2); Radius = [tex]\sqrt{10}[/tex]

Step-by-step explanation:

(x  - 7)^2 + (y - 2)^2 = 10

center = (7, 2)

Radius = [tex]\sqrt{10}[/tex]

Answer:

(x - 7)^2 + (y - 2)^2 = 10

center = (7, 2)

Radius = √10

Angles: Arcs & Angles need help thank you!!

Answers

Answer:

See answers below

Step-by-step explanation:

1) The typr of triangle in a semicircle is a right angle. Hence the measure of  m<ABC  is 90degrees

2) m<DEF = 1/2(144)

m<DEF = 144/2

m<DEF = 72degrees

3) From the trinagle

4x+3 + x+7 +90 ==180

5x + 100 = 180

5x = 180-100

5x = 80

x = 80/5

x = 16

<QRD =  x+7

m<QRD = 16 + 7

m<QRD = 23degrees

4)  Angle in the same segment are equal

5x-37= 3x+1

5x - 3x = 1+37

2x = 38

x = 38/2

x =19

arc NM = 2m<P

Mark said, “in the data set,4 5, 5, 8, the mean and mode the same.” Is he correct? Explain why or why not

Answers

Answer:

Mark is wrong.

Step-by-step explanation:

The mean of the data set is 5.5 because 4 + 5 + 5 + 8= 22. 22 divided by 4= 5.5. The mode is the number which shows up the most. 5 shows up the most in the data set, however 5 is not equal to 5.5. Therefore, Mark is incorrect.

Separation of variables

[Division Property of Equality] Isolate y terms together:                             [tex]\displaystyle \frac{1}{y}\frac{dy}{dx} = sec^2(x)[/tex][Multiplication Property of Equality] Isolate x terms together:                   [tex]\displaystyle \frac{1}{y}dy = sec^2(x)dx[/tex]

Solve the equation. Then check your solution. – two-fifths + a = One-fifth a. Three-fifths c. StartFraction 3 Over 10 EndFraction b. Negative one-fifth d. Negative three-fifths

Answers

Answer:

a = Negative one-fifth

Step-by-step explanation:

The given equation is :

[tex]\dfrac{2}{5}+a=\dfrac{1}{5}[/tex]

We need to find the value of a.

Subtract 2/5 from both sides.

[tex]\dfrac{2}{5}+a-\dfrac{2}{5}=\dfrac{1}{5}-\dfrac{2}{5}\\\\a=\frac{1}{5}-\frac{2}{5}\\\\a=\dfrac{-1}{5}[/tex]

So, the correct answer is Negative one-fifth. Hence, the correct option is (b).
