Answer:

No Possible Triangles

Step-by-step explanation:

sinA/a =  sinB/b

 From the reference sheet (reciprocal version).

sinR/640 =  sin30/310  

Plug in values.

sinR=   (640 (sin30))/ 310≈1.0322581

Evaluate.

R=sin  −1  (1.0322581)=ERROR

Sine cannot be greater than 1.

Distance» [tex] \frac{490}{2} [/tex]

Distance» 245

Answer:

245 units

Step-by-step explanation:

Anna drives her car at a speed of = 70 kmph

To Find:

How much distance will she cover in 3 hours 30 minutes.

Solution:

We'll use here the formula of Speed,then plug the values which are given.

Speed = Distance/Time

70 = D/7/2

7/2*70 = Distance

7*35 = Distance

Distance = 245

We can conclude that Anna can cover 245 units in 3 hrs 30 mins.

Answer:

3 for the left one, and 5 on the right one.

Step-by-step explanation:

The scale factor is 2 because they are scaled from each other, meaning they have proportional side lengths. (The angles are also the same <hint for the next question>)

If the top side is 2.5, and the bottom is 5, then you divide to find the scaled factor since they correlate to each other.

If the side lengths on A is multiplied by 2, you can do that to the missing sides to find the answers.

Answer:

y= 80/9

Step-by-step explanation:

Given

" y varies directly as x" and "as the square of z" so y = x* z²* some number

if y =25/9 when x= 5, z= 1 and y = x*z²* some number

then 25/9  = 5 * 1² * some number

      5*(5/9) = 5 * some number

therefore y = x* z²* (5/9)

y= ? when x=1 , z= 4

y = x * z² * (5/9)

y = 1 * 4² * (5/9)

y = 16*5 / 9

y = 80/9

Answer:

y = (5/2)x + 13/2

y = 3

y = -2x + 6

Step-by-step explanation:

The left part of the function which is a line sloping up to the right contains points (-3, -1) and (-1, 4) which can be read off the graph.

Since we have two points, we can find the equation.

You can use the slope formula given two points, but I will read it off the graph with rise and run.

Go from point (-3, -1) to point (-1, 4) by going up 5 (the rise) and going right 2 (the run).

slope = rise/run = 5/2

y = mx + b

y = (5/2)x + b

Use point (-1, 4) for x and y and solve for b.

4 = (5/2)(-1) + b

8/2 + 5/2 = b

b = 13/2

y = (5/2)x + 13/2

This is the first answer.

The middle part is a horizontal line in which every point has y-coordinate 3.

The equation is:

y = 3

This is the second answer.

The right part is the line that slopes down to the right. We can read two points easily. Use points (3, 0) and (2, 2).

Start at (3, 0). Go left 1 (run of -1) and up 2 (rise of 2). Now you are at point (2, 2).

slope = rise/run = 2/(-1) = -2

Now we find the y-intercept on the graph. After you get to (2, 2), keep moving with the same run and rise of the slope. Go left 1 and up 2 to point (1, 4). Go again left 1 and up 2 to (0, 6). Point (0, 6) is on the y-axis, so it is the y-intercept.

b = 6

y = mx + b

y = -2x + 6

This is the third answer.

Step-by-step explanation:

Probabilities are used to determine the chances of an event.

The probability that the two bags are selected for extra screening is 0.02

The given parameters are:

[tex]n = 2[/tex] --- number of bags

[tex]p = 14\%[/tex] --- the probability that a bag is selected for extra screening

The probability that the two bags are selected for extra screening is:

[tex]P(2) = p^n[/tex]

So, we have:

[tex]P(2) = (14\%)^2[/tex]

Express percentage as decimal

[tex]P(2) = (0.14)^2[/tex]

[tex]P(2) = 0.0196[/tex]

Approximate

[tex]P(2) = 0.02[/tex]

Hence, the required probability is 0.02

Using the uniform distribution, it is found that there is a 0.25 = 25% probability that the next fracture will occur in the last half mile of the two mile interval.

The uniform distribution has two bounds, a and b.  

The probability of finding a value above x is:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

In this problem, the distribution is uniform over 2 miles, thus [tex]a = 0, b = 2[/tex].

The probability of a failure on the last half-mile is P(X > 1.5), thus:

[tex]P(X > 1.5) = \frac{2 - 1.5}{2 - 0} = 0.25[/tex]

0.25 = 25% probability that the next fracture will occur in the last half mile of the two mile interval.

Step-by-step explanation:

72÷9= 8, so the boat was only doing 8mph going upstream (against the current) the return trip downstream only took 4 hours. 72÷18=4 meaning the boat was traveling at 18mph downstream (no current) there is a 10mph difference between upstream and downstream therefore the current had to be running at 10 mph. so the speed of the tug boat is 8mph without a current and the current is running at 10mph.

If 1 share had an initial cost of $0.000007, then 3,000,000 shares would be worth

(3,000,000 shares) × ($0.000007/share) = $21

If the price increases to $0.01 per share, then the same number of shares would have a value of

(3,000,000 shares) × ($0.01/share) = $30,000

So you've gained a net profit of $30,000 - $21 = $29,979, which corresponds to a

$29,979 / $21 = 1,427.57 = 142,757%

increase in value.

Answer:

Step-by-step explanation:

∠ A and ∠ FCE are corresponding angles and are congruent , then

∠ A = 150°

∠ FCE and ∠ C are vertically opposite angles and are congruent , then

∠ C = 150°

∠ FCE and ∠ ECB are adjacent angles on a straight line and sum to 180°

∠ ECB = 180° - ∠FCE = 180° - 150° = 30°

∠ E = 180° - (30 + 45)° ← sum of angles in a triangle

∠ E = 180° - 75° = 105°

∠ CBE and ∠ D are same- side interior angles and sum to 180° , then

∠ D = 180° - 45° = 135°
