triangle DEF is formed by connecting the midpoints of the sides triangle ABC. The lengths of the sides of DEF are shown. what is the length of AB​

Answers

The same length of DE

The requried length of the AB is given as AB = 16.

What is the triangle?

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Here,
Since triangle DEF is formed by connecting the midpoints of the sides of triangle ABC, the length of the sides of triangle DEF is half the length of the corresponding sides of triangle ABC. That is:

DE = 1/2 AB

EF = 1/2 BC

FD = 1/2 AC

We can use the information about the lengths of the sides of triangle DEF to find the length of AB.

Since DE = 8 and EF = 10, we can use the triangle inequality to find FD:

FD + DE > EF

FD + 8 > 10

FD > 2

Similarly, since EF = 10 and FD = 12, we can use the triangle inequality to find DE:

DE + EF > FD

DE + 10 > 12

DE > 2

Finally, since DE = 8 and FD = 12, we can use the triangle inequality to find EF:

EF + FD > DE

EF + 12 > 8

EF > -4

Since all sides of a triangle must have positive lengths, EF cannot be negative. Therefore, the inequalities we have found imply that:

2 < FD < 12

2 < DE < 8

0 < EF < 10

Since DE = 1/2 AB and EF = 1/2 BC, we can write:

AB = 2DE = 2(8) = 16

BC = 2EF = 2(10) = 20

Therefore, the length of AB is 16.

CosB = 13/33 for which of the following
triangles?

Answers

Answer:

A

Step-by-step explanation:

they tell me what came out

The triangle for which Cos B = 13/33 is triangle D.

The given triangle is a right triangle. In order to use Cos B, the value of the adjacent side and the hypotenuse has to be known. The adjacent side is the side that is adjacent to angle B. The hypotenuse is the longest side of the triangle.

Triangle A: cos b = adjacent / hypotenuse

hypotenuse = √13² + 33² = 35.5

Cos B = 13 / 35.5

Triangle B: cos b = adjacent / hypotenuse

hypotenuse = √13² + 33² = 35.5

Cos B = 33 / 35.5

Triangle C: cos b = adjacent / hypotenuse

Adjacent = √33² - 13²  = 30.3

Cos B = 30.3 / 33

Triangle D: cos b = adjacent / hypotenuse = 13/33

From the figure which is greater between a and Q​

Answers

Answer:

a

Step-by-step explanation:

the horizontal distance is shorter so the angle will be greater.

added:

tan a = AD/2a

tan Q - AD/3a

Just looking at the fractions AD/2a and AD/3a, the denominator of AD/2a is smaller so the resulting calculation will be greater, hence a is the larger angle.

Arsenic is an element that occurs naturally in groundwater, but a mean greater than 8.0 parts per billion indicates that the groundwater has been contaminated. Local officials are concerned about a well in an area of the city near a factory. On 50 consecutive days, water was randomly sampled from the well. Assume the water in the well has a mean arsenic level greater than 8.0 ppb. Based on the data, if we find moderate/strong evidence against the null hypothesis and conclude the mean arsenic level of the water is greater than 8.0 ppb, we have made ____________.

Answers

Answer:

Based on the data, if we find moderate/strong evidence against the null hypothesis and conclude the mean arsenic level of the water is greater than 8.0 ppb, we have made ____________.

a correct decision.

Step-by-step explanation:

Since there is enough evidence to conclude that the mean level of arsenic is greater than 8.0 ppb, the correct decision has been made.  There is no type I or type II error.   The type I error (called a false positive) occurs if we reject the null hypothesis when it is true.   Since we have simply rejected the null hypothesis when the alternate hypothesis is true, and the null hypothesis should be rejected, a correct decision has been made.

Answer:

If 5 shirts and 5 sweaters cost $205, and 6 shirts and 9 sweaters cost $294, what is the cost of one shirt and what is the
cost of one sweater?

Answers

Answer:

one shirt 25.00 one sweater 16.00

Step-by-step explanation:

$\text{one shirt: }\$25,\text{ one sweater: }\$16$

Let x be the cost of one shirt and y be the cost of one sweater; then

5x+5y6x+9y=205=294

The augmented matrix for this system of equations is

[5659205294]

Using Gaussian elimination, divide row one by 5 to get

[161941294]

Multiply row one by −6 and add the result to row two to get

[10134148]

Divide row two by 3 to get

[10114116]

After back substitution, y=16 and x=25.

The cost of one shirt is $25 and cost of sweater is $16.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let x be the cost of one shirt and y be the cost of sweater.

5 shirts and 5 sweaters cost $205

5x+5y=205...(1)

6 shirts and 9 sweaters cost $294

6x+9y=294...(2)

Multiply equation (1) with 6 and equation (2) with 5.

30x+30y=1230..(3)

30x+45y=1470...(4)

Subtract 3 and 4

30y-45y=1230-1470

-15y =  -240

Divide both sides by 15

y=240/15

y=16

Now plug in y value in any of the equation

5x+16(5)=205

5x + 80 = 205

5x = 125

Divide both sides by 5

x=25

Hence, the cost of one shirt is $25 and cost of sweater is $16.

A line is perpendicular to y = - x - 2 and intersects the point (-5, 10)

Answers

Answer:

y = x + 15

Step-by-step explanation:

If two lines are perpendicular to each other, they have opposite slopes.

The first line is y = - x - 2. Its slope is -1. A line perpendicular to this will have a slope of 1.

Plug this value (1) into your standard point-slope equation of y = mx + b.

y = 1x + b or y = x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (-5, 10). Plug in the x and y values into the x and y of the standard equation.

10 = (-5) + b

Simplify.

10 = -5 + b

Now, add 5 to both sides to isolate b.

15 = b

Plug this into your standard equation.

y = x + 15

This equation is perpendicular to your given equation (y = -x - 2) and contains point (-5, 10)

A submarine travels 5.5 km due East from its base and then turns and travels due North for 3.4 km.
How far away is the submarine from its base?
Give your answer rounded to 1 DP.​

Answers

Answer:

6.5km

Step-by-step explanation:

If you make a diagram, you'll see the submarine forms a right angle triangle with the base, where the hypotenuse is the length from the submarine to its base, and 5.5 and 3.4 are the side lengths. To find the hypotenuse, use the formula a^2+b^2=c^2.

5.5^2+3.4^=c^2

41.81=c^2

6.466=c

Round it to one decimal point and you get 6.5km.

To solve this problem, you could use a graphing calculator to graph the given equation. Then, determine when this line crosses 100. It crosses when x = 15.539. Therefore, we would have to round up to 16 so it is at least 100.

You could use the quadratic equation to solve: 100 = x^2 -12x + 45

Either you will get 16. If you use the quadratic formula, make sure to only use the positive answer.
