Answer:

L = 24,873.6 miles

Step-by-step explanation:

Length of the Circumference

Given a circle of radius r, the length of the circumference, or line surrounding the shape is:

The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:

r=7,917.5/2=3,958.75 miles

Assuming a plane flies around the equator at ground level, the distance it would travel is:

L = 24,873.6 miles

Answer:

30

Step-by-step explanation:

mode is the number that occurs most of the time

since 30 appears twice in the data set

while the other numbers only appear once,

30 is the mode

▪︎Mode is the most frequently occurring element in a given data set.

The given data set :

[tex] =\tt 30,28,30,45,40,37,35[/tex]

Let us first arrange these numbers in ascending order :

[tex] =\tt 28,30,30,35,37,40,45[/tex]

As we can clearly observe, the number 30 occurs the most frequently.

Thus, the mode of this data set = 30

Therefore, the correct option is (b) 30

Answer: The answer is most likely 0.3

Step-by-step explanation:

The difference between the theoretical and experimental probabilities of getting heads is 0.3.

This question is solved using the concepts of theoretical and experimental probabilities.

----------------------------

Theoretical probability:

A fair coin means that it is equally as likely to be heads or tails, so 0.5 theoretical probability of getting heads.

----------------------------

Experimental probability:

Out of 10 trials, 2 resulted in heads, so 2/10 = 0.2 experimental probability of  getting heads.

----------------------------

Difference:

0.5 - 0.2 = 0.3

The difference between the theoretical and experimental probabilities of getting heads is 0.3.

Answer:

T is equal to I divided by pr. [tex]t=\frac{I}{pr}[/tex]

Step-by-step explanation:

This is the equation for interest.

I is interest.

P is the principal

r is the interest rate

t is the time in years

you have to isolate for t.

Because multiply p times r times t, divide both sides by pr due to the fact that division is the inverse operation of multiplication

Then you are left with t= i divided by pr.

Answer:

x>-3

Step-by-step explanation:

I used a calculator

Answer:

x = 18 cm

Step-by-step explanation:

(4x)^2 = 3(4x)(x+6)

16x^2=3(4x)(x+6)

divide both sides by 4x

4x = 3(x+6)

4x=3x+18

x = 18

Answer:

£469

Step-by-step explanation:

So 6 years mean it has depretiatied to 5.5*6 = 33% meaning the car is worth 67% of what it was originally worth

First do 700 / 100 to find what the car is equal to when it's 1% which is 7, after than multiply its new value of 67%,

so 7*67 = £469

Answer:

$469

Step-by-step explanation:

To find the amount of money that the car loses in value every year, multiply the price of the car by the rate its value depreciates at in decimal form.

The car depreciates at a rate of 5.5% per year. To find 5.5% in decimal form, move the decimal point to left twice. So, 5.5% in decimal form is 0.055.

700 * 0.055 = 38.5

The car loses $38.50 in value every year, so the car's value will depreciate by 6 times that amount in 6 years.

$38.50 * 6 = $231, so the car will lose $231 in value after 6 years.

700 - 231 = 469

The car will be worth $469 in 6 years.

Answer:

The answer is 986.55 kg.

Step-by-step explanation:

When asked to find 137% of 720.11 kg, we can take the percentage, 137%, and convert it into a decimal by moving the decimal point over to the left twice.

137% = 1.37

After converting the percentage to a decimal point, we can multiply the original given value by the decimal.

720.11 kg x 1.37 = 986.5507 kg

And then we round to the nearest hundredths place, which will give us 986.55 kg.

The required evaluation of 137% of 720.11 kg would be 986.55 kg.

The percentage is defined as a ratio expressed as a fraction of 100.

We have to determine the evaluation of 137% of 720.11 kg.

⇒ 137% of 720.11

137%  is expressed as 15/100 in fractional form

⇒ (137/100)(720.11 )

137/100  is expressed as 0.95 in decimal form

⇒ (1.37)(720.11 )

Apply the multiplication operation, and we get

⇒ 986.55

Therefore, 137% of 720.11 kg would be 986.55 kg.

#SPJ2

Answer:

first sub in (0,-2) to get

-2 = ab^0, but b^0 = 1

so a=-2

so far we have

y = -2b^x

now use the other point (2,-50)

-50 = -2(b^2)

b^2 = 25

b= ±5

however in exponentional equations the base is usually positve, so now you have

y = -2(5^x)

sub in x=-2 and you got it.

Answer:

49.92

Step-by-step explanation:

Square = 30

5 x 6 = 30

Half Circle = 9.42

6 x 3.14 = 18.84 divided 2 since it’s a half circle equals 9.42

Triangle = 7.5

3 x 5 = 15 divided by 2 = 7.5

So, 30+ 9.42 + 7.5 = 49.42

Answers + Explanation:

1. x + 7 =10

if you know some number + 7 is 10, you know that number must be 3.

so, x = 3

the other way you can solve this would be:

x + 7 = 10

subtract 7 from both sides of the equation

x + 7 - 7 = 10 - 7

x = 3

2. Use the same strategy:

x - 8 = -5

add 8 to both sides of the equation

x - 8 + 8 = -5 + 8

x = 3

3. x + 3 = 6

subtract 3 from both sides of the equation

x + 3 - 3 = 6 - 3

x = 3

4. x + 6 = 3

subtract 6 from both sides of the equation

x + 6 - 6 = 3 - 6

x = -3
