The angles with measures x and (4x) are complementary angles.

Which is the value of x?

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.

Answer:

P = 3.6 + 6 + 3.6 + 6 = 19.2 units

Step-by-step explanation:

distance between (-3,-2) and (-5,-5) =

Sqrt[(-5-3)^2+(-5 - -2)^2]

Sqrt (4+9) = 3.6

d = (-5,-5) and (1,-5) =

Sqrt[(1 - - 5)^2 + (-5 - - 5)^2]

= sqrt (36 + 0) = 6

d = (1,5) and (3,-2)

Sqrt[(1 - - 3)^2 + (-5 - - 2)^2]

Sqrt(4+9) = 3.6

d = (3,-2) and (-3,-2)

Sqrt[(-3-3)^2 + (-2 - - 2)^2]

Sqrt (36+0) = 6

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.

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.

what a difficult question !!! Do not ask such difficult questions ..lol

Answer:

see explanation

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°

Answer:

[tex]8k + 10 + 9k + 1 = k(8 + 9) + (10 + 1) \\ = 17k + 11[/tex]

The options that are true include:

A. One pound of pistachios plus 1 pound of almonds cost $20.

C. Reducing the number of pounds of almonds by 1 results in a total cost of $40.

E. The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.

Cost of almond = a

Cost of pistachios = a + 4

Therefore, based on the information given, the equation to solve the question will be:

2(a + 4) + 3a = 48

Collect like terms

2a + 8 + 3a = 48

5a = 48 - 8

5a = 40

a = 40/5

a = 8

Almonds cost $8

Pistachios cost $12

In conclusion, the correct options are A, C, and E.

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

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]

Step-by-step explanation:

1. 1/4 × 2/2 = 2/8 (denominator is 8)

2. 5/8 × 1 = 5/8 (denominator is 8)

Therefore, the common denominator is 8.

it would probably be 7, since 1 hour and 30 minutes would be 90 minutes, and she read 10 pages in that long, it would most likely be one page every 10 minutes, but since she read 10 in 90 minutes and not 9, I believe we would add 1 extra page to the amount she read in one hour, and since one hour is 60 minutes, it would probably be 6 + 1, which is 7.

hopefully Im right and this was helpful.
