TRAY A tray in a school cafeteria has the dimensions shown. Find the area of the tray.

**Answer:**

This is your answer

Please help me with this

2)

Okay so because the right side is two times the length and width of the left side, we need to divide 20 and 14 by 2 which gives us 10 and 7. That means x+2 = 10 so we need to subtract 2 from each side which gives you 8. Therefore, x = 8.

20/2 = 10

10 - 2 = 8

x = 8

An urn contains 8 green and 9 white balls. Six balls are randomly drawn from the urn in succession, with replacement. That is, after each draw, the selected ball is returned to the urn. What is the probability that all 6 balls drawn from the urn are white? Round your answer to three decimal places.

Answer:

The probability is 0.022

Step-by-step explanation:

Firstly, we need to get the total number of balls in the urn

mathematically, we have this as ;

8 + 9 = 17

now, the probability of selecting a white ball will be the number of white balls divided by the total number of balls

Mathematically, we have this as 9/17

Now, since the event is carried out with replacement, the probability for the six times is the same

So, we have the probability as;

(9/17)^6 = 0.022

Mario walked 250 ft south then 430 ft west. How far is he from the starting point? Round off answers to the nearest hundredths place.

Answer:

497.39 FEET

Step-by-step explanation:

Please check the attached image for a diagram of the bearings

This question can be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

we want to determine the value of c

250² + 430² = 247400

c = √247400 = 497.39 feet

Practice Triangle Ratios (Sides) Find the value of c. Round to the nearest tenth!

**Answer:**

30.6688

**Step-by-step explanation:**

We usually use the formula SOHCAHTOA meaning Sine = opposite side/hypotenuse Cosine = opposite side /hypotenuse then Tangent = Opposite side/Adjacent side. We then say Tan61°= x/17 to get the height as 30.6688 PS/ Hypotenuse is the slanting side of the triangle

what is the rate of change of y=0.5•x-2

**Answer:**

0.5

**Step-by-step explanation:**

rate of change is just a synonym for slope and the equation for slope is y=mx +b where m is the slope so 0.5=m and if m= slope then 0.5=slope=rate of change :)

Ana participated in a charity walk. She

raised $0.25 for each 1/2

mile that she

walked. The first day, Ana walked 11 miles.

The second day, she walked 14 miles.

How much money did Ana raise?

**Answer:**

if $0.25 for each mile, then $1.00 =1 mile.

so the first day would be = $1=1mile

$n=11 miles

= 1n= 11×1=$ 11

**Step-by-step explanation:**

and the 2nd day is = 14×1= $14.

So the answer is 14+11=$25.00

The proportional relationship between the distance driven and the amount of time driving is shown in the

following graph.

Which statements about the graph are true ?

A. The y- coordinate of point A represents the distance driven in 4 hours.

B. The distance driven in 1 hour is 80 km

C. None of the above

The **distance** driven in **1 hour** is **80 km**. Therefore, **option B **is the **correct answer**.

The given time graph shows the proportional relationship between the distance driven and the amount of time driving.

What is a distance-time graph?If an **object** moves along a **straight line**, the **distance** travelled can be represented by a **distance-time graph**. In a distance-time graph, the **gradient** of the line is equal to the **speed** of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

From the **graph**, we can see that **object A **moved **400 km** in** 5 hours** time.

So, in 1 hour the **distance** travelled by object =400/5=**80 km**

Therefore, **option B **is the **correct answer**.

A central angle of a circle of diameter 6 cm measures 86°. What is the length of the intercepted arc?

A)

2.8 cm

B)

4.5 cm

C)

5.1 cm

D)

9 cm

Answer:

B)

4.5 cm

Step-by-step explanation:

The formula for arc length when our central angle is in degrees =

2πr(θ/360)

θ = 86°

Diameter = 6cm Radius = Diameter /2

Radius = 6cm/2 = 3cm

Hence,

Intercepted arc length = 2 × π × 3 (86/360)

= 2 × π × 3 × 0.2388888889

= 4.5029494701 cm

Approximately = 4.5 cm

Option B is the correct answer

A zoologist studies a population of 800 rabbits. He tags 160 rabbits at random, of which 37 have blue eyes. Based on this data, about how many rabbits in the population have blue eyes?

Answer:

185

Step-by-step explanation:

Population size = 800

Sample size = 160

Number of blue-eyed rabbit in sample = 37

The proportion of blue-eyed rabbit in the sample is :

p = number of blue eyed rabbit / sample size

p = 37 / 160 = 0.23125

Estimated number of blue eyed rabbit in population :

p * population size

0.23125 * 800

= 185

In a lottery, the top cash prize was $642 million, going to three lucky winners. Players pick five different numbers from 1 to 53 and one number from 1 to 46. A player wins a minimum award of $400 by correctly matching two numbers drawn from the white balls (1 through 53) and matching the number on the gold ball (1 through 46). What is the probability of winning the minimum award?

**Answer:**

[tex] \frac{10}{53 \times 46 \times 26} [/tex]

**Step-by-step explanation:**

The probability of matching the number drawn on the gold ball is

[tex] \frac{1}{46} [/tex]

The number of possible pairs of numbers from 1 to 53 is

[tex] \binom{53}{2} = \frac{53 \times 52}{2} = 53 \times 26[/tex]

Choosing 5 numbers, you are choosing 10 different pairs:

[tex] \binom{5}{2} = \frac{5 \times 4}{2} = 10[/tex]

Therefore the probability of correctly matching the drawn pair is

[tex] \frac{10}{53 \times 26} [/tex]

Thus, the probability of winning (matching the pair AND the gold ball) is

[tex] \frac{10}{53 \times 46 \times 26} [/tex]

Of course it needs information too, but the kind of information it needs can be generated only by vigorous popular debate. We do not know what we need to know until we ask the right questions, and we can identify the right questions only by subjecting our ideas about the world to the test of public controversy. Information, usually seen as the precondition of debate, is beter understood as its by product.
