Step-by-step explanation:

Given

[tex]Distance = 402\ miles[/tex]

[tex]Gasoline = 23/2\ gallons[/tex]

Required

Determine boats with better rates

This question requires options which are missing. However, I'll give an explanation on how to determine the right answers.

First, determine the rate of the given boat by dividing distance by amount of gasoline.

[tex]Rate = Distance/Gasoline[/tex]

[tex]Rate = 402\ miles / \frac{23}{2}\ gallons[/tex]

[tex]Rate = 402\ miles * \frac{2}{23\ gallons}[/tex]

[tex]Rate = \frac{402\ miles * 2}{23\ gallons}[/tex]

[tex]Rate = \frac{804\ miles}{23\ gallons}[/tex]

[tex]Rate = 34.96\ miles/gallon[/tex]

For the list of mission options, calculate the rate using the same formula used above... then compare the results.

Take for instance, we have a boat with:

[tex]Distance = 500\ miles[/tex]

[tex]Gasoline = 10\ gallons[/tex]

Rate would be:

[tex]Rate = 500\ miles/10\ gallons[/tex]

[tex]Rate = 50\ miles/gallons[/tex]

By comparing these rates, we have that:

[tex]50 > 34.96[/tex]

So, this new boat has a better rate than the given boat.

Apply this on the missing options

Answer:

Percentage = 91.67%

Step-by-step explanation:

Number of eligible voters = 240,000,000

Number of voters so far = 70,000,000

Number of estimated voters = 150,000,000

Total number of participants (voters) = 70,000,000 + 150,000,000 = 220,000,000

To find the percentage;

[tex] Percentage = \frac {220,000,000}{240,000,000} * 100 [/tex]

[tex] Percentage = \frac {11}{12} * 100 [/tex]

[tex] Percentage = 0.9167 * 100 [/tex]

Percentage = 91.67%

Therefore, the percentage of eligible voters that will participate in this year's election is 91.67%

The trapezoid is isosceles and NK is its height, therefore

Since ∠KDN = 45°, the triangle NKD is isosceles and so

MF  = ND as trapezoid is isosceles and therefore diagonals are equal

Answer:

420

Step-by-step explanation:

Answer: 2.6

​​

Step-by-step explanation:

1: Split the number into its whole number component and it fractional component.

      2 3/5=2+3/5.

2: For the denominator, recognize that 5x20=100.

      Multiple=20.

3: Multiply both the numerator and denominator by the multiple 20.

      3x20, 5x20.

4: Simplify.

      60/100.

5: Simplify.

      0.6

6: Combine the whole number component with the decimal.

      2.6✅

Answer:

3.6/12, or 0.3

Step-by-step explanation:

To determine a slope on a graph, it's always the "rise over run", or "fall over run" if it's a negative slope.

In this case, the rise of 3.6 meters would represent the top number, and 12 meters would be 12 meters, so it's 3.6/12.

Answer: Well the answer would be the second one cause it more the paragraph is more telling us about it rather than pursuing us they are giving examples and stories not persuading the reader

Answer:

Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:

to switch into y=mx+b form do this:

3x-y=5

-y=5-3x

y=-5+3x

y=3x+(-5)

2y-15x=8

2y=8+15x

y=4+7 1/2x

y=7 1/2x+4

THe slope of any line in y=mx+b form is m. Therefore in this equation:

y=3x+(-5)     3 is the slope

The y intercept of any line is the +b:

y=7 1/2x+4 -therefore 4 in this equation is our y intercept.

Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)

since 3 is our slope and 4 is our y intercept the equatuon is :

y=3x+4

NOw all we need to do is move this into standard form:

y=3x+4

-3x+y=4

-3x+y=4 is your final answer

The answer is

✔ 36.6

Since Yuna ran three times as many kilometers so here expression should be 3k and the answer is 36.6

Expressions are considered to be mathematical statements that have at least of two terms comprised of numbers or variables that should be linked. It could be of addition, subtraction, multiplication, or division.

First, write the expression as  3k

Second, substitute 12.2 in for the variable, k.

Third,  simplify by ✔ multiplying 3 and 12.2.

And, finally, The answer is 36.6

Answer:

Step-by-step explanation:

Step one:

the first day

distance= 650miles

time taken= 10 hours

speed= distance/time

speed= 650/10

speed= 65miles per hour

Step two:

the second day

distance= 540mile

time taken= 8 hours

speed= distance/time

speed= 540/8

speed= 67.5miles per hour

Step three:

the difference between the two speeds is =67.5-65= 2.5

therefore on the second day, the speed is 2.5 miles per hour faster

Answer:

Students at canyon middle school = 350

Step-by-step explanation:

Students at canyon middle school = x

Band = 1/2x + 30

Athletics = 3/5x - 5

athletics.If the number of students who are in band is equal to the number of students in athletics

1/2x + 30 = 3/5x - 5

1/2x - 3/5x = -5 - 30

5x-6x/10 = -35

-x/10 = -35

= -x(1/10)= -35

x = -35 ÷ -1/10

= -35 × -10/1

= 350

x = 350

Students at canyon middle school = 350
