50 POINTS PLUS BRAINLIEST!

Mathematics
1 answer:
OLga [1]3 years ago
3 0

Answer:

2500 meals in 20 hours.

Step-by-step explanation:

The easiest point to see is (2,250). The other point (since you need 2) is the origin. This is a graph. It does not require any greater accuracy than looking at the point that is chosen.

x = 2

y = 250

k = ?

y = k*x                                                     equation

250 total meals packed = k * 2 hours  Substitute values

k = 250 /2

k = 125 meals / hour

Let x = 20 hours

k = 125 meals / hour

y = ?

y = 125 * 20

y = 2500 meals

How do i divide fractions ΓΓΓ
Free_Kalibri [48]

Dividing fractions is basically the same thing as multiplying but by the reciprocal. I will give an example.

1/2 divided by 1/3

To solve this you do 1/2 multiplied by 3/1 so you switch the numerator and denominator.

A blackjack is a 10-point card and an ace for a value of 21. Use your answers to parts (a), (b), and (c) to determine the probab
kondor19780726 [428]

Answer:

Results:

0.1432

0.0045

0.0905

0.0483

Step-by-step explanation:

Step a:

P(A or 10, A or 10) = 20/52 * 19/51 = 5/13 / 19/51 = 95/663 = 0.1432

Step b:

P(A A) = 4/52 * 3/51 = 1/13 * 1/17 = 1/221 = 0.0045

Step c:

P(10 10) = 16/52 * 15/51 = 4/13 * 5/17 = 20/221 = 0.0905

Step d:

P(A 10 or 10 A) = 2 * 4/52 * 16/51 = 2/13 * 16/51 = 32/663 = 0.0483

As well we get the probability by subtracting a,  b and c:  

P(blackjack): 0.1432 - 0.0905 - 0.0045 = 0.0482

In the straightedge and compass construction of the parallel line below, which of the following reasons can you use to prove tha
Eva8 [605]

Answer:

D.

Step-by-step explanation:

Lines EG and CD are cut by transversal CF.

By construction, ∠FEG=∠FCD. These two angles are corresponding angles.

Since two corresponding angles are congruent, then lines EG and CD are parallel (by  converse of the corresponding angles postulate).

Converse of the Corresponding Angles Postulate: If the corresponding angles formed by two lines and a transversal are congruent, then lines are parallel.

Mathematical connection A lighthouse casts a revolving beam of light as far as the pier
Alexandra [31]

The light's coverage area is given mathematically as i.e. Area=\pi d^{2}

Given that a lighthouse casts a revolving beam of light as far as they peir and asked the area is covered.

The revolving beam of light covers the whole space i.e entirely 360°

I.e. it forms a circle-like region

Area of circle = \pi r^{2}{ where r is the radius of circle}

Let's assume the distance traveled by light as "d"

as it forms a circular region, it forms a circle of radius "d"

Mathematical connection i.e. area of the region

⇒area of circular region=\pi d^{2} {where d is the radius of region}
