Answer:

x = 29°

Step-by-step explanation:

the Δ on the right has 3 angles whose measures are 30°, 74°, and 76° (you get 76° because it forms a linear pair with an angle that is 104°; you get 74° by adding 30 and 76 and subtracting the sum from 180°.

the Δ on the left has 3 angles whose measures are 45°, 29°, and 106° (you get 106° because it forms a linear pair with an angle that is 74°; you get 29° by adding 45 and 106 and subtracting the sum from 180°.

∡x is a vertical angle with the angle that measures 29° and vertical angles are congruent

Type the missing numbers in this sequence:<br> -99, -97,<br> -93,<br> -89,<br> -87

iragen [17]

Answer:

Hope I helped ꒰⁎˃ ॢꇴ ॢ˂⁎꒱

Step-by-step explanation:

-99, -97, -93, -89, - 87

Lets look at the differences

+2, +4, +4, +2

Doesn't really seem like a specific pattern, but I can assume it goes like +2, +4, +4, +2, +4, +4, +2, +4, +4,

We are on +4 then, so the answer would be (-87)+4, which is -83

This sequence follows no pattern though, so if there is an option that there is not enough info to solve the sequence, pick that.

a forest ranger in a 140-foot observation tower sees a fire moving in a direct path toward a lake. the angle of depression to th

Setler79 [48]

Answer:

1675 ft

Step-by-step explanation:

For us to calculate how close the windmill is to the fire, if we imagine it as a triangle, the distance from watch tower to the fire will be:

tan θ= opposite/adjacent

opposite=140 ft

adjacent = x

θ=3°

Thus;

tan 3 = 140/x

x=140/tan 3

x = 2,671.359 ft

Now, the distance from watch tower to windmill will be:

tan θ=opposite/ adjacent

θ=8°

opposite=140 ft

adjacent=y

thus

tan 8 = 140/y

y = 140/tan8

y=996.15 ft

Now, the distance between fire and wind mill will be:

x - y = 2671.359 - 996.15

x - y = 1675.209 ≈ 1675 ft

If the average volume flow of blood through the aorta is 8.5 × 10-5 m 3/s and the cross-sectional area of the aorta is 3.0 × 10

valkas [14]

The average speed of blood in the aorta is 0.2833 m/s

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

From the question, to calculate the average speed:

Average speed = Volume rate / cross sectional area

Average speed = 8.5 * 10⁻⁵ / (3 * 10⁻⁴) = 0.2833 m/s

The average speed of blood in the aorta is 0.2833 m/s

What is the median. I have 3 more questions that have to deal with the median.

Rom4ik [11]

Answer:

Step-by-step explanation:

Median - The middle number in a list of numbers starting from least to greatest.

Knowing this, we can start.

The first step is to rewrite all the numbers from least to greatest

15, 19, 28, 32, 43, 52, 66, 72, 72, 81

Now cross off a number from the least and greatest until there is 1 or 2 numbers left

19, 28, 32, 43, 52, 66, 72, 72

28, 32, 43, 52, 66, 72

32, 43, 52, 66

43, 52

If you are left we 1 number, that is your answer. If you are left with 2 numbers, there is an extra step

In the case that you have 2 numbers, you need to add them together, and divide by 2

43 + 52 = 95

95 ÷ 2 = 47.5

Thus 47.5 is our answer

The pressure applied on any object can be calculated by using the following equation.

lapo4ka [179]

The pressure applied inside a container having an inner area of 16 square meters over which a force of 1,306 newtons is applied is 82Pa

<h3>What is pressure?</h3>

Pressure is defined as the ratio of the force to the cross sectional area of an object. Mathematically;

Pressure = Force/Area

Given the following parameters

Force = 1306 Newton

Area = 16 square. meters

Substitute the given parameters into the formula

Presssure = 1306N/16m²

Pressure = 81.625N/m²

<u>Convert N/m² to pascal</u>

Pressure = 82Pa

Hence the pressure applied inside a container having an inner area of 16 square meters over which a force of 1,306 newtons is applied is 82Pa
