Answer:

0.15 km/min

Step-by-step explanation:

V=S/T

=50/360

≈0.15km/min

Answer:

a run of 6

Explanation:

AB=4 , AC=3

If you create a rise of 8 you doubled the rise of AB [4x2], so you would double the run of AC as well [3x2] = 6

Step-by-step explanation:

Answer:

14.52 seconds

Step-by-step explanation:

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.

Answer:

a) 21 √m inches

b) 13√2/2 m

Step-by-step explanation:

a) we want to find the perimeter of an equilateral triangle

An equilateral triangle is one which sides has the same equal length

The perimeter of this triangle is the sum of the lengths of the three sides

Mathematically, we have this as:

7 √m + 7 √m + 7 √m

= 21 √m inches

b) we want to calculate the perimeter of the given rectangle

Mathematically, we can calculate the perimeter of a rectangle using the formula below;

P = 2(l + b)

where l represents the length of the rectangle and b represents the breadth of the rectangle

From the given shape;

l = √50 m, b = 1/2 √32

So, we have the perimeter follows;

2( √32/2 + √50)

= √32 + √50/2

√32 = 4√2

√50 = 5√2

Thus, we have;

4 √2 + 5 √2/2

= (8 √2 + 5 √2)/2 = 13√2/2

Answer:

60

Step-by-step explanation:

[tex]180 - 2(60) = 60[/tex]

Answer:

60°

Step-by-step explanation:

A triangle with two 60° angles has another 60° because 180-(60+60)=180-120=60°.

Also, this is an equilateral triangle.

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.

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.

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.

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.
