Answer:

So, we know that the speed of the aircraft is 600 miles /per hour/. The question is, how many miles does it travel over 6 hours?

Since “per hour” means it travels that far in 1 hour, we need to take that speed (600mph) and multiply it by 6, since we were asked about the distance in 6 hours.

So:

600*6=3600

And we get a total of 3600 miles traveled in 6 hours, as opposed to 600 miles in 1 hour.

The answers are:

6,871,000

and

18,333,000

Answer:

6871000

18333000

Step-by-step explanation:

all the numbers before thousands will be zeros and the number that decide whether thousands will be added one or remains the same is the number before the thousands which is hundreds, if it's 0-4 that means the thousands remain the same at it was before and all the numbers before it become zeros, but if it's 5-9 that means thousands will be added one and all the numbers before it become zeros.

so the answer is:

6871000

18333000

Answer:

8.38 m^3

Step-by-step explanation:

The volumes are in proportion to the cubes of their radii.

Compare volumes in the form  big cone / small cone.

[tex]\frac{131}{V_\text{small}}=\frac{5^3}{2^3}\\\frac{131}{V_\text{small}}=\frac{125}{8}[/tex]

"Cross multiply."

[tex]125V_\text{small}=8\cdot131\\125V_\text{small}=1048\\V_\text{small}=\frac{1048}{125}\approx 8.34\text{ cm}^3[/tex]

Answer:

Volume of cone = 90 ft³

Step-by-step explanation:

diameter of cone = 6ft

radius of cone = 3ft

height = 10ft

Volume of cone = [tex]\frac{\pi r^2h}{3}[/tex]

V = (3 × 3 × 3 × 10)/3

V = 270/3

V = 90 ft³

Answer:

208m²

Step-by-step explanation:

Okay, so you can split this abomination into a rectangle, another rectangle, and a square, so we're going to start with the rectangle to the far left:

The formula for the area of a rectangle or square is length x width, so we just have to plug:

4 x 8 = 32

Now we do the next rectangle, but we have to figure out the length first, so:

4 + 4 = 8

Now we plug:

8 x 4 = 32 (I now realize that the rectangles are even and we could've just multiplied the first one by two, but it's always good to check)

Now we do the square:

12 x 12 = 144

Now we add it all together:

32 + 32 + 144 = 208

So the area of the figure is 208m²

if this is wrong, let me know so I can fix it

Answer:

the number of miles did he drive the truck is 276 miles

Step-by-step explanation:

The computation of the number of miles did he drive the truck is as follows

Let us assume the mileage be m

Now according to the question

0.8m + 18.99 = 239.79

0.8m = 239.79 - 18.99

0.8m = 220.8

m = 276

Hence, the number of miles did he drive the truck is 276 miles

The above represent the linear equation

Answer:

596

Step-by-step explanation:

Each term of the arithmetic sequence is 9 greater than the previous term.

Since the first term is 29, then 29+9 = 38, the second term in the sequence.  Likewise, the third term, 47, is 9 greater than the previous term, 38.  47 is also 2(9) greater than the first term, 29.

Therefore, finding the 64th term in the sequence would be the same thing as adding 9 to the first term (29) a total of n-1, or 64-1 times. Instead of adding, one can simply multiply 29 by 63, since 64-1 = 63.

29 + 63(9)

= 29 + 567

= 596

So, the 64th term of the arithmetic sequence is 596.

Answer:

b=3/4

Step-by-step explanation:

((3/4)x)/2=9/32

The length of the base will be 3/4. The length of the base from formula of area of triangle.

The area of the triangle is half of the length and base of the triangle.Area of triangle is found as;

[tex]\rm A= \frac{1}{2} \times L \times B\\\\ A=\frac{9}{32} \\\\ \frac{9}{32} =\frac{1}{2} \times \frac{3}{4} \times B \\\\ B=\frac{3}{4}[/tex]

Hence,the length of the base will be 3/4.

Answer:

12 and 53

Step-by-step explanation:

let 'x' = one number

let 'y' = other number

System of Equations:

x + y = 65

x - y = 41

Substitution Method:

x = 41 + y

41 + y + y = 65

2y = 24

y = 12

x + 12 = 65

Answer:

The sum of the first ten terms is -35.

Step-by-step explanation:

The first term of an arithmetic sequence is 10, and its common difference is -3.

We want to find the sum of the first 10 terms of this sequence.

Remember that the sum for an arithmetic sequence is given by:

[tex]\displaystyle S=\frac{k}{2}\left(a+x_k\right)[/tex]

Where k is the number of terms, a is the initial/first term, and x_k is the last term.

Since our initial term is 10, a = 10.

And since we want to find the sum of the first ten terms, k = 10.

So, we will need to find the last or tenth term. We can write an explicit formula. The standard explicit formula for an arithmetic sequence is:

[tex]x_n=a+d(n-1)[/tex]

Where a is the initial term and d is the common difference.

So, by substituting, we acquire:

[tex]x_n=10-3(n-1)[/tex]

Then the tenth or last term is:

[tex]x_{10}=10-3(10-1)=10-3(9)=10-27= -17[/tex]

Then the sum of the first ten terms will be:  

[tex]\displaystyle S_{10}=\frac{10}{2}(10+(-17))=5(-7)=-35[/tex]

Answer:

-35

Step-by-step explanation:

[tex]a_{1}[/tex] = 10+(-3)(0) = 10

[tex]a_{10}[/tex] = 10+(-3)(9) = -17

[tex]S_{10}[/tex] = 10[(10 -17)/2] = 10(-7/2) = -70/2
