Triangle ABC has vertices A (1,1) B (7,1) C (4,9) (A)Find the perimeter of triangle ABC. (B) Find the area of triangle ABC

Answer:

perimeter = 6+2√73 ≈ 23.09 units
area = 24 units²

Step-by-step explanation:

It can help to draw a figure.

The altitude of this isosceles triangle is 8 units, and it splits the base into equal lengths of 3 units. Using the Pythagorean theorem, we find the length of a side to be ...

BC = AC = √(3² +8²) = √73

The perimeter is the sum of the lengths of those two sides and the base:

P = 2(√73) +6 ≈ 23.088 . . . units

The area is given by the formula ...

A = 1/2bh

A = (1/2)(6 units)(8 untis) = 24 units²

The perimeter is 6+2√73 ≈ 23.09 units.

The area is 24 units².

A data set consists of the data given below plus one more data point. When the additional point is included in the data set the

belka [17]

Answer:

Value of additional data point is 31.

Step-by-step explanation:

We are given the following data set:

34, 18, 18, 40, 11, 22, 30, 25, 19, 21, 45 34, 18, 18, 40, 11, 22, 30, 25, 19, 21, 45

Formula:

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{487}{20} = 24.35$

The old mean is 24.35

A new data was added in the data. The new mean is 24.667

We have to find the value of additional point.

Let x be the added point in the data set.

Thus, we can write:

$24.667 = \displaystyle\frac{487+x}{21}\\\\x = 21(24.667)-487 = 31.007 \approx 31$

Thus, value of additional data point is 31

In a paint factory, an old conveyer line has filled 10 barrels of paint, and is filling more at a rate of 2 barrels per minute.

Leviafan [203]

Answer:

see below

Step-by-step explanation:

First line:

y = mx+b where m is the slope and b is the y intercept

y = 2x + 10

Second line

y = mx+b

y = 3x+0 since there are no barrels filled on this line when they flip the switch

Setting the two equations equal

2x+10 = 3x

Subtract 2x from each side

2x+10-2x= 3x-2x

10 = x

Each line will have filled 10 barrels when they numbers are equal.

Answer

(4x-5) = -20 (2x+8) = 2

Step-by-step explanation:

2 x − 8 = 2 2x-8=2 2x−8=2. Add 8 to both sides. Simplify 2 + 8 2+8 2+8 to 10. Divide both sides by 2. If its wrong then I’m very sorry but I’m sure this is correct.
