Answer:

3450 miles

Step-by-step explanation:

Multiply the number 17.25 by 200 since the boat is traveling for 200 hours and each hour is 17.25 miles to get 3450 miles which is your answer.

Answer:

[tex]\boxed {\boxed {\sf 3,450 \ miles}}[/tex]

Step-by-step explanation:

Distance can be found by multiply the speed by the time.

[tex]d=st[/tex]

Where d is the distance, s is the speed, and t is the time.

1. Define Variables

The speed is 17.25 miles per hour and the time is 200 hours.

[tex]s= 17.25 \ mi/hr[/tex]

[tex]t= 200 \ hr[/tex]

2. Calculate Speed

Substitute the values into the formula.

[tex]d=17.25 \ mi/hr * 200 \ hr[/tex]

Multiply. The hours (hr) will cancel each other out and leave miles as the units.

[tex]d=17.25 \ mi *200\\[/tex]

[tex]d=3450 \ mi[/tex]

The voyage was 3,450 miles

Answer:

a₁₃ = 4096

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 1 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{2}{1}[/tex] = 2 , then

a₁₃ = 1 × [tex]2^{12}[/tex] = 4096

Answer:

B- Negative

Step-by-step explanation:

Since both numbers are on the left side of zero, they are both negative, and in your situation, A= -4.5 and B= -9. By trying to do -4.5+(-9), it will become -4.5-9, thus being negative

Answer:

The original number is (i)

The whole amount is (ii)

Step-by-step explanation:

So when finding a number in a percent you wanna see how much that percent will go into that number. So like if I said how many times does 60% go into 200 you would have to see how many times the number 200 would go into 60%. does this make sense? If so this is how you can find your answer.

Sorry if I'm wrong I hope you get this right!! Stay beautiful ❤️

Answer:

90 i think im sorry if its wrong

Step-by-step explanation:

Answer:

We know that the distributive property says this:

a(b+c) = ab + ac

If we apply this to our case, we can put

3a(2b+c) = 3a * 2b + 3a * c

When we multiply numbers and letters, we should multiply both of them:

3a * 2b + 3a * c = 3*2*a*b + 3*a*c = 6ab +3ac

We can use this when we find a number multiplied by a parenthesis..

Answer:

6ab + 3ac

Step-by-step explanation:

3a(2b) + 3a(c)

6ab + 3ac

Answer:

9 inches

Step-by-step explanation:

Here, we want to know the greatest length of the third side

We apply the triangle inequality theorem here

To get the third side, then the sum of the lengths of the two must be greater than the measure of the third side

let us call the third side x

Then;

5 + 5 > x

10 > x

The highest whole number before 10 is 9: so it is the greatest possible whole number the base of the isosceles triangle can have

Step-by-step explanation:

42+4n<50, so n<4

Answer:

42+4n ≥ 50, so n ≥ 2

Answer:

1. The value 40÷40.01 is close to 1.

2. The value 4÷40.01 is much less than 1.

3. The value 4000÷40.01 is greater than 1.

Step by step explanation:

The given numbers are 4, 40 and 4000.

Divide each number 4, 40 and 4000 by 40.01

 The value __40___÷40.01 is close to 1.

The value __4___÷40.01 is much less than 1

The value __4000___÷40.01 is greater than 1.

Answer:

1/5 times 24 is 24 1's, so we will divided 24 by 5, but since were estimating it will be 25/5 and we will get 5. That means 1/5 times 24 as an estimate will be 5. Hoped I helped!

Answer:

128

Step-by-step explanation:

Answer:

Verticle     x=128°

Step-by-step explanation:

A vertical angle is each of the pairs of opposite angles made by two intersecting lines.

And vertical angles are congruent so x = 128° as well!

Let as consider, we need to find the fixed fee.

Given:

Cost of each ticket = $18

Number of tickets = 5

Total cost = $93

To find:

The fixed fee.

Solution:

Let x be the fixed fee..

Cost of 1 ticket = $18

Cost of 5 ticket = $(5 × 18)

                         = $90

Total cost 5 tickets = Fixed fee + Cost of 5 tickets

[tex]93=x+90[/tex]

[tex]93-90=x[/tex]

[tex]3=x[/tex]

Therefore, the fixed fee is $3.

Answer: if your asking to simplify then the answer is

3x+5

Step-by-step explanation:

Answer:

Solution is invalid

Step-by-step explanation:

Let the time when they will have the same water content be x hours

At x hours;

For the first tank, the content will be;

50 + 10x

For the second;

29 + 3x

Equating both, will give us x

29 + 3x = 50 + 10x

We will get x as a negative number here

Since number of hours can not be negative, the solution is invalid

Answer:

56

Step-by-step explanation:

80 x (7 / 10) = 56

Answer:

x=2/3, y=0

Step-by-step explanation:

3x + 7y = 2,

6x - 5y = 4

Make the x coefficient the same in both equations.

3x + 7y = 2

(whole thing multiplied by 2)

6x + 14y = 4

Now subtract the equations to eliminate the x variable.

 6x + 14y = 4

-(6x - 5y   = 4)

        19y  = 0

           y = 0

Substitute 0 for y in one of the equations.

3x + 7(0) = 2

         3x = 2

           x = 2/3

Answer:

well your equation has 2 equal signs in it but imma take a guess and say the first one is supposed to be a plus sign so

Answer:

60

Step-by-step explanation

Okay, uh... this is gonna be confusing to explain.

So a hexagon's angles add up to 720. This means, we can find each angle's supplementary angle by subtracting each value we know away from the total.

So, we know the inside angle of angle 6 is 90.

So: 720-90=630

Now, typically, you would divide by the remaining angles, but we have basically 2 angles of different values since 1, 2, and 3 are equal, and 4 and 5 are equal.

However, we know that 1, 2, and 3 are 10 degrees less than 4 and 5. So if we "add" 10 degrees to each of those angles we get:

10*3=30

630-30=600

Now we made it as though each angle (1-5) is equal. So now we divide by 5.

600/5=120

This means the supplementary of angles 4 and 5 is 120, so we subtract that value from 180 since a straight angle is 180.

180-120=60

Now, to check this we reverse it.

(120*2)+(120*3)+(10*3)+(90)=

240+360+30+90=

600+30+90=

600+120=

720.

Um... I think this is it?? Your school is scary :o

Answer:

Not a function. The inverse is

[tex]y = \sqrt{ \frac{x + 5}{2} } [/tex]

and

[tex]y = - \sqrt{ \frac{x + 5}{2} } [/tex]

Step-by-step explanation:

Any even-degree polynomial functions that are inverted will not be a function.

[tex]f(x) = 2 {x}^{2} - 5[/tex]

Let y = f(x)

[tex] y = 2 {x}^{2} - 5[/tex]

To proceed the inverse, swap the x-term and y-term.

[tex]x = 2 {y}^{2} - 5[/tex]

Convert into function form.

[tex]x + 5 = 2 {y}^{2} \\ 2 {y}^{2} = x + 5 \\ {y}^{2} = \frac{x +5 }{2} [/tex]

The reason why inverted even-degree polynomial function cannot be a function because the inverse graph doesn't pass line test.

Thus the answer is

[tex]y = \sqrt{ \frac{x + 5}{2} } \\ y = - \sqrt{ \frac{x + 5}{2} } [/tex]

Answer:

8

Step-by-step explanation:

First, you add the 7 to both sides. Then you divide both sides by 9. This gets you left with x by its self on one side. x = 8

Answer:

x=8

Step-by-step explanation:

x=8 because if you add 65 and 7 you get 72 and when you divide it by 9 you get 8.
