Judy's class: 76, 78, 85, 87, 89, 92, 98

Answers

Answer:

Ken class has a median of 84 while Judy class a median of 87

Step-by-step explanation:

Ken class has a median of 84 while Judy class a median of 87

Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.

what does this mean 4x + 6y=9
12x + 18y=27

Answers

Answer: Infinite solutions

Step-by-step explanation:

Solve4x+6y=9for x:

4x+6y=9

4x+6y+−6y=9+−6y(Add -6y to both sides)

4x=−6y+9

4x /4 = −6y+9 /4

(Divide both sides by 4)

x= −3 /2 y+ 9 /4

Substitute

−3 /2 y+ 9 /4

for x in 12x+18y=27:

12x+18y=27

12( −3 /2 y+ 9 /4 )+18y=27

27=27(Simplify both sides of the equation)

27+−27=27+−27(Add -27 to both sides)

A ladder that is 13 feet long leans against a building .The bottom of the ladder is 5 feeet away from the base of the building .how far up the side of the building does the ladder reach?​

Answers

Length of the ladder = 13 m

Foot of the ladder from the wall = 5 m.

The upper end of the ladder is (13^2–5^2)^0.5 = 12 m above the ground.

In 1 second the foot of the ladder is 7 m from the wall, while the top end is (13^2–7^2)^0.5 = (169–49)^0.5 = 120^0.5 = 10.95 m. Then the top moves 1.05 m downwards.

In 2 seconds, the foot of the ladder is 9 m from the wall, while the top end is (13^2–9^2)^0.5 = (169–81)^0.5 = 88^0.5 = 9.38 m. Then the top moves 3.62 m downwards.

In 3 seconds, the foot of the ladder is 11 m from the wall, while the top end is (13^2–11^2)^0.5 = (169–121)^0.5 = 48^0.5 or 6.93 m. Then the top moves 6.07 m downwards.

So, if the foot of the ladder moves at a constant rate of 2 m/s the top end of the ladder moves downwards which varies from second to second.Answer: The lader will form the hypotenuse. Length of hypotenuse = 13m.

Let us take the horizontal distance between the wall and the ladder as ‘ground’. This g = 5m

wall ^ 2 + ground ^ 2 = 13^2 = 169

w^2 + g^2 = 169

w^2 + 25 = 169. Thus, w^2 = 144. Thus, w = 12

Rate of change of ground distance = dg / dt = 2m/s (given).

In the equation w^2 + g^2 = 169, differentiate the equation with respect to time.

2 w dw/dt + 2 g dg/dt = 0

2 (12) (dw/dt) + 2 (5) (2) = 0. So, 24 dw/dt + 20 = 0

dw/dt = -20 / 24 = -5 / 6

Thus, the height of the wall is decreasing at a rate of -5/6 m / s (that is, -0.833m/s)

The minus sign denotes that the height of the ladder is falling.

A. Tanisha is 3, and Bess is 6.
B. Tanisha is 3, and Bess is 9.
c. Tanisha is 6, and Bess is 9.
D. Tanisha is 6, and Bess is 12.

Answers

Answer: a

Step-by-step explanation: because bess it says she has 6 and is 3 it says have of 6 is 3 so it is 3

The age of Tanisha is 6 years and the age of Bess is 12 years. Therefore, option D is the correct answer.

We need to find the age of Tanisha and Bess.

What is an equation?

A statement that the values of two mathematical expressions are equal (indicated by the sign =).

Let the age of Tanisha be x.

Bess is 6 years older than Tanisha.

Now, Bess=x+6

Tanisha is half as old as Bess.

Now, Tanisha=1/2×Bess

⇒x=1/2×(x+6)

⇒x=6

So, Tanisha's age=6 years and Bess's age=12 years.

Solve the two-step equation. 14=31.7-3x

Answers

Answer:

x=5.9

Step-by-step explanation:

First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.

Nicholas has a pepper shaker in the shape of a cylinder. It has a radius of 9 mm and height of 32 mm. How much pepper will for in the shaker

Answers

By using the fοrmula fοr the vοlume οf a cylinder, the pepper shaker can hοld apprοximately 8,159.15 cubic millimetres οf pepper.

What is the vοlume οf a cylinder ?

The fοrmula tο calculate the vοlume οf a cylinder:

V = πr²h

where:

V = vοlume

r = radius

h = height

Tο calculate the vοlume οf the pepper shaker, we need tο use the fοrmula fοr the vοlume οf a cylinder.

In this case, we have:

r = 9 mm

h = 32 mm

Sο the fοrmula becοmes:

V = π(9 mm)²(32 mm)

V = π(81 mm²)(32 mm)

V = 81π(32) mm³

V ≈ 8,159.15 mm³

Therefοre, the pepper shaker can hοld apprοximately 8,159.15 cubic millimeters (οr milliliters) οf pepper.
