Step-by-step explanation:

Answer:

I believe the answer is 5.8 miles

Step-by-step explanation:

I believe this is the correct answer, although it is possible I am wrong.

This is how I solved this problem:

I divided 10,560 feet by 2, which equals 5280 feet in a mile

Then I divided 30,375 feet by 5280 feet to get 5.7528409

Since there is no way this is the correct simplification, you need to round to the nearest tenth.

5.7528409 is about 5.8 miles

Answer:

12 hours.

Step-by-step explanation:

A motorist takes 5 hours to travel 300km

This means that his velocity, in km per hour, is given by:

v = 300/5 = 60 km/h

How long will it take to travel 720 km at same average speed?

720 km, 60 an hour. So

720/60 = 12

It will take 12 hours.

Answer:

Step-by-step explanation:

2 opposite semicircle are same

diameter = 9m

radius = 4.5m --- (diameter = 1/2radius)

area of semicircle = 1/2 × π × radius²

= 1/2 × 3.14 × 4.5×4.5

= 31.79m²

2 semicircles area = 31.79 × 2

= 63.8m²

______________________________

______________________________

other 2 opposite semicircle are same

diameter = 20m

radius = 10m --- (diameter = 1/2radius)

area of semicircle = 1/2 × π × radius²

= 1/2 × 3.14 × 10×10

= 157m²

2 semicircles area = 157 × 2

= 314m²

______________________________

______________________________

length = 20m ----- ( given )

breadth = 9m ----- ( given )

area = length × breadth

= 20 × 9

= 180m²

______________________________

______________________________

AREA of whole figure = 63.8 + 314 + 180

= 557.8m²

Step-by-step explanation:

All interior angles of any triangle add up to 180°

? = 180° - 43° - 84°

? = 53°

Answer:

Its B. 53

Step-by-step explanation:

To find the unknown angel you need to add the number you already have AKA 43 and 84 you need to add up to 180 so 43+84+53= 180

Answer: 4 and 1/4

Step-by-step explanation:

1st question is 4-- count the points that fall above the line

2nd question is 2 out of 8, or 1 out of 4

there are only 2 players who played at least 17 matches AND scored about 5000. There are 8 players who played at LEAST 17 matches

Answers:

1. 4

2. ¼

Explanations:

1. the question is asking how many players were awarded more points than the prediction of the line of best fit (trend line), which can be translated to how many dots are above the line on the graph. 4 dots can be counted above the line

2. 8 players played at least 17 tournaments. of these 8 players, only 2 scored more than 5000 ranking points.

thus, to find the probability, we take 2 ÷ 8 = ¼

i hope this helps! :D

Answer: 3 7/15

Step-by-step explanation: You first do 1 /5 plus 2/3.But they don't have the same denominator so you make it the same which you can make it to 15 so you make both denominator of   1/5 and 2/3. So 1 /5 change to 3/15 and 2/3 change to 10/15.Now add 3/15 to 10/15 which is 13/5.After that you do 4 times 13/5.But change 4 to a fraction to make it easy which is 4/1.Now multiply 4/1 by 13/5 which gives you 52/15 .Finally change 52/15 to a mixed number which is 3 7/15.

Hope it helps and look at pic below to see the steps :)

Answer:

(x+2)^2+(y-3)^2=100

Step-by-step explanation:

so the equation is (x-h)^2+(y-k)^2=r^2

(h,k)=center

r^2=radius

in this case (h,k)=(-2,3)

r^2=r^2

10^2=100

(x-(-2))^2+(y-3)^2=100

Hope fully that helps :)

Answer:

the cost of each is  £10 and  £8 respectively

Step-by-step explanation:

Let us assume the cost of per DVD be x

And the cost of per CD be y

Now as per the question

The following equations should be made

3x + 4y = £62.00

4x + 3y = £64.00

Now multiply by 4 in equation 1 and 3 in equation 2

12x + 16y = £248

12x + 9y = £192

7y =  £56

y =  £8

Now put the value of y in any of the above equation

3x + 4( £8) =  £62

3x +  £32 =  £62

3x = 30

x =  £10

Hence, the cost of each is  £10 and  £8 respectively

Answer:

A.) f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1

Step-by-step explanation:

The first four terms of a sequence are shown below.

Let

f(1) = 9

f(2) = 5

f(3) = 1

f(4) = -3

Therefore we know that

f(2) - f(1) = 5 - 9

f(2) - f(1) = - 4

f(2) = f(1) - 4

f(3) - f(2) = 1 - 5

f(3) - f(2) = - 4

f(3) = f(2) - 4

f(4) - f(3) = -3 - 1

f(4) - f(3) = - 4

f(4) = f(3) - 4

Hence the answer is A.) f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:

3 miles

Step-by-step explanation:

1 hour = 3,600 seconds (3,600 ÷ 10 = 360)

360 x 44 = 15,840 Feet

1 mile = 5,280 feet

15,840 feet ÷ 5,280 feet = 3 miles

Answer:

90 cubes.

Step-by-step explanation:

First we find volume of the cuboid.

Volume = l x b x h = 20 x 18 x 16 = 5760 cm³

Now,

Volume of a single cube = l³ = 4³ = 64

No of cubes that can be cut out from the cuboid is

= Volume of cuboid/ volume of cube

= 5760/ 64

= 90 cubes

Every fifth pretzels is tested for weight.

Collect all the multiples of 5 till 25.

So, pretzels that are tested for weight are: 5, 10, 15, 20, 25.

Every third pretzel is tested for size

Collect all the multiples of 3 till 25.

So, pretzels that are tested for size are: 3, 6, 9, 12, 15, 18, 21, 24.

Now, pretzels that are not checked or tested are: 1, 2, 4, 7, 8, 11, 13, 14, 16, 17, 19, 22, 23.

They are 13 in number.
