If a dart were thrown randomly at the dart board shown below, what is the
probability that it would land in the area between the circle with radius 2 mm
and the circle with radius 8 mm?
A. 31%
B. 48%
C. 33%
D. 45%

Answer:

8800km

Step-by-step explanation:

If 1cm = 400km

then you have to substitute in 22cm instead of 1cm making it..

22x400=8800.

Hope this helps.

Answer:

12

Step-by-step explanation:

Since this is simple interest the equation will be P*T*R=I  T=time which is 1 year. P=money invested or borrowed  (aka princable) which is 400$. R=Annual rate is 3% per year and I= Interest after the number of years (aka answer) Hope this helps :)

Answer:

I = 400 x 0.03 x 1

Step-by-step explanation:

$400 is the principal, 0.03 is the decimal value for the annual rate, and the time is 1 year.

Answer:

C

Step-by-step explanation:

Point B is at -0.5, -1 is not greater than -0.5.

Point A is at -1 and is not greater than Point B, because Point B is at -0.5.

Therefore, it is none of the above.

Answer:

C

Therefore, it is none of the above.

Answer: C.) 4/27

Step-by-step explanation:

Given that:

One out of three cards is a winner :

P(winning) = 1 / 3

Therefore, P(not winning) = P(losing) :

1 - P(winning) = 1 - 1/3 = 2/3

Probability that shenice will first win on her third try can be interpreted as:

1st try = lose, 2nd try: lose, 3rd try : win

P(losing) × p(losing) × p(winning)

(2/3) × (2/3) × (1/3)

4 / 27

Probability of first winning on third try = 4/27

Answer:

volume of water in the tank when it its half full

The capacity of the water tank = (5.04) /2 = 2.52 m³

2,520 litres

Step-by-step explanation:

Dimensions of a water tank:

Length (l) = 2.0 m,

wide (w) = 1.4 m,

Depth (h)= 1.8 m,

Volume of the tank (V)

LWH

2.0m × 1.4m × 1.8 m

= 5.04 m³

= 5.04 × 1000 litres

/* 1m³ = 1000 litres */

5,040 litres

Therefore,

The capacity of the water tank = 5.04 m³

5,040 litres

The cargo plane's speed was 500 mph.

Answer: 84 3/8 or 84.375 inches cubed

Step-by-step explanation:

4 1/2 * 5 = 22 1/2

22 1/2 * 3 3/4 = 45/2 * 15/4 = 675/8

675/8 = 84 3/8 or 84.375

Answer:

v = -23/4 = -5 3/4

Step-by-step explanation:

4= - 3/(v+5)

Multiply each side by (v+5)

4 (v+5) = -3

Distribute

4v+20 = -3

Subtract 20 from each side

4v +20-20 = -3-20

4v = -23

Divide by 4

4v/4 = -23/4

v = -23/4

Step-by-step explanation:

f is not a function because you can see that two of the points are (2,5) and (2,2). A function can only have one corresponding y-coordinate for every x-coordinate and since this is not the case here, f is not a function.

Answer:

One half of X are employees.

One third of X are employee's spouses.

We add one half PLUS one third:

1/2 + 1/3 = 3/6 + 2/6 = 5/6

Then we subtract that fraction from one whole, or 1,

to see what fraction is left.  That is, we say

1 minus 5/6

which is

1 - 5/6

Now write 1 as 6/6

6/6 - 5/6

We get 1/6

So 1/6 is left.  Now we need to make that into

a percent by multiplying it by 100 and tacking on a "%"

1/6 � 100

1/6 � 100/1

100/6

50/3

16 2/3 %

So 16 2/3 % of the people in

attendance are neither employees

nor employee's spouses.

Now let's check:

1/2 are employees.  That's 50%

1/3 are wmployee's spouses. That's 33 1/3%

15 2/3 % are neither employees nor employee's spouses.

Add them up

50     %

33 1/3 %

16 2/3 %

--------

99 3/3 %

And 99 3/3% = 100%

Answer:

The yellow trapezoid equals to 6.

Step-by-step explanation:

Assuming that two green items equals to two purple items and one yellow trapezoid, we can make the equation 5+5=2+2+x. Simplifying both sides, we get 10=4+x. If we subtract 4 from both sides and isolate x, we get that x=6.

Answer:

yellow trapezoid = 6

Step-by-step explanation:

since the green crescent equals 5, and there are two on the left side, that would equal 10, so the right side also should equal 10 too. The purple teardrops equal two, and there are two on the right side, so the total of teardrops on the right side is equal to 4. Since both sides need to equal to 10, and we only have 4, we need to find the amount of the yellow trapezoid. To do that you need to subtract 4 from 10, to get 6, which is the amount of the yellow trapezoid.

Answer:

x=35

Step-by-step explanation:

Since a quadrilateral's interior angles add up to 360°, we get this:

360-85-20=360-4x+x

340-85=360-3x

255=360-3x

-105= -3x

Multiply both sides by -1

105=3x

3x=105

Divide both sides by 3

x=35

Answer:

495 students

Step-by-step explanation:

The 4 part of the ratio is the number of boys.

Divide the number of boys by 4 to find the value of one part of the ratio.

220 ÷ 4 = 55 ← value of 1 part of the ratio, thus

5 parts = 5 × 55 = 275 ← number of girls

Number of students = 220 + 275 = 495

Answer:

Step-by-step explanation:

[tex]220 \: boys \\ 4:5 = 4 + 5 \\ boys \: = \frac{4}{9} \times x = 220 \\ = \frac{4x}{9} = \frac{220}{1} [/tex]

[tex]4x = 1980 \\ \frac{4x}{4} = \frac{1980}{4} \\ x = 495 \\ total \: no \: of \: students \: = 495 \\ [/tex]

Answer:

b. y=-x+2

Step-by-step explanation:

hi!

the slope intercept form is y=mx+b where m is the slope, and b is the y intercept.

since the y intercept is postive 2, we can first eliminate choices A and C since they show a y intercept of negative 2, not positive 2.

next, we can eliminate d since the line of the graph is going downwards, meaning that the slope or m is negative.

Therefore, the correct answer is b.

u can also use a graphing calculator if youre unsure and plug in each equation and see if it matches with the graph.

Answer:

4.68 in

Step-by-step explanation:

4.825-0.145=4.68 in

The inside diameter of the pipe is 4.68 inches.

A straight line that runs through the sideways of a body or figure, particularly a circle or sphere, is called as a diameter of a circle or sphere.

Given:

The outside diameter of a pipe is 4.825 inches.

If the pipe wall is 0.145 inches thick,

the inside diameter of the pipe,

= 4.825 - 0.145

= 4.68

Therefore, the diameter is 4.68 inches.

Answer: The radius and the cord must be perpendicular to each other.

Step-by-step explanation:

A cord is a line from a point of circumference of a circle to another point of the circumference of the circle without passing through the centre.

A radius is a line from the centre of a circle to the circumference of the circle.

When the radius line intersect and bisects a cord of a circle, the radius and the cord must be perpendicular to each other.

Answer:

if in a circle a radius bisects a chord then the radius is perpendicular to the chord,

C). y = ln x + 4

Step-by-step explanation:

First off, we can cancel out the [tex]e^{x}[/tex] graphs.

Now looking at the graph, one can see that when x = 1, y = 4.

So for each [tex]ln[/tex] function, plug in 1 for x.

In doing this, one will find that y = ln x + 4 is the only [tex]ln[/tex] graph that produces 4 when x = 1.

Answer: $500

Step-by-step explanation:

Hi, since both credit options accumulate the same amount of interest:

1000+125x=1300+110x

Solving for x(number of months)  

125x-110x =1300-1000

15x = 300

x =300/15

x= 20 months

Replacing x =25 in one equation:

1000+125x =

1000+125(20)=

1000+2500= $3500

Finally, we have to subtract the amount of the purchase (3000) to the result obtained:

3500-3000=$500

Answer:

Option D. 91/4950

Step-by-step explanation:

The following data were obtained from the question:

Barcelona (B) = 23

Real Madrid (R) = 23

Liverpool (L) = 22

Manchester City (M) = 18

Juventus (J) = 14

Total (T) = 100

Next, we shall determine the probability of the first pick i.e probability of Juventus. This is illustrated below:

P(J1) = n(J) /n(T)

P(J1) = 14/100

Now, the picking is done without replacement. The next pick being Juventus will reduce in number and likewise the total number will also reduce i.e

Juventus = 13

Total = 99

Therefore, the probability that the 2nd pick is Juventus is given below:

P(J2) = 13/99

Now, we can obtain the probability that the 1st and 2nd student prefer Juventus as follow:

P(J1 and J2) = P(J1) x P(J2)

P(J1) = 14/100

P(J2) = 13/99

P(J1 and J2) = P(J1) x P(J2)

P(J1 and J2) = 14/100 x 13/99

P(J1 and J2) = 7/50 x 13/99

P(J1 and J2) = 91/4950

Therefore, the probability that the 1st and 2nd student prefer Juventus is 91/4950
