Answer:

I don't know what you want to know so I assume you want to find out his miles in minutes:

Divide 40 with 60

Which is 2/3

So Max rode 2/3 miles in a minute

Step-by-step explanation:

Answer:

4 hours if going ten mph and 2 hours if going 20 mph

Answer:

180

Step-by-step explanation:

Answer:

2nd option

Step-by-step explanation:

The ratios on both sides must be equal

[tex]\frac{15}{6}[/tex] ( divide numerator/ denominator by 3 )

= [tex]\frac{5}{2}[/tex] ≠ [tex]\frac{3}{2}[/tex] , then not a proportion

[tex]\frac{4}{5}[/tex] ( multiply numerator/ denominator by 3 )

= [tex]\frac{12}{15}[/tex] , this is a proportion

[tex]\frac{9}{21}[/tex] ( divide numerator/ denominator by 3 )

= [tex]\frac{3}{7}[/tex] ≠ [tex]\frac{6}{7}[/tex] , then not a proportion

[tex]\frac{10}{16}[/tex] ( divide numerator/ denominator by 2 )

= [tex]\frac{5}{8}[/tex] ≠ [tex]\frac{2}{8}[/tex] , then not a proportion

Answer:

1. 18/8

2. 16/20

3. 15/28

4. 12/24

Answer:

The odds for are 50% and the odds against are 50%.

Step-by-step explanation:

On a die, there is 6 possibilities 2, 3, and 5, are 3 of them.

This means there is a 3/6 chance that it will land on one of those numbers, and there is also a 3/6 chance it will land on 1, 4, or 6.

3/6 is equivalent to 50% and 1/2.

Answer:

3 3/4 = 15/4

Step-by-step explanation:

To turn a mixed number into an improper fraction, multiply the whole number with the denominator of the proper fraction. Add the numerator of the proper fraction to this product to obtain the numerator of the improper fraction.

Answer:

x=27/2

Step-by-step explanation:

1/2-1/3x=-4

subtract 1/2 from both sides

1/2+-1/3x -1/2=-4 -1/2

Group like terms

-1/3 ⋅ x +1/2+(-1/2)=-4 -1/2

Combine the fractions

-1/3 ⋅ x+0=-4 -1/2

Convert the integer into a fraction

-1/3 ⋅ x=-8/2 -1/2

Combine.

-1/3 ⋅ x= -9/2

Isolate the x:

-1/3x ⋅ 3/-1= -9/2 ⋅ 3/-1

1x=-9/2 ⋅ 3/-1

x= -9 ⋅ -3/2

x=27/2 as your answer

Answer:

12

Step-by-step explanation:

The Constant (K) is equal to 8/2 aka 0.25 making the formula now y = 0.25 × x

We have y as 3 so

3 = 0.25 × x we take the 0.25 to the other side by dividing on both sides.. this makes it cancel out on the right.

x is now equal to 3/0.25 which is 12. X = 12

Answer:

Is the answer 9 for the last x

Answer: No association

Step-by-step explanation:

There is absolutely no pattern going on. This means that the miles ran per week are not really affecting the standing heartbeat. Therefore, I'd say there is no association.

Answer: the slope 4

Step-by-step explanation:

the slop is y^2 - y^1 / x^2 - x^1 = 0 -8 / -1 - - 3 = 8/2 = 4

Answer:

3d+4

Step-by-step explanation:

(5d+6)–(2d+2)

To find the opposite of 2d+2, find the opposite of each term.

5d+6−2d−2

Combine 5d and −2d to get 3d.

3d+6−2

Subtract 2 from 6 to get 4.

3d+4

Answer:140 because you have to divided by 1

Step-by-step explanation:

Answer:

A≈653.45

Step-by-step explanation:

Solution

A=2πrh+2πr2=2·π·8·5+2·π·82≈653.45127

Answer:

tan x = 3/4

Step-by-step explanation:

The hypotenuse of the triangle is 10 ft.

For angle x, the opposite leg is 6 ft, and the adjacent leg is 8 ft.

tan A = opp/adj

tan x = 6 ft / 8 ft

tan x = 3/4

Answer:

[tex]\frac{9x}{y^3}[/tex]

Step-by-step explanation:

[tex]\frac{\left(3x^2y^4\right)^3}{3x^5y^{15}}[/tex]

[tex](3x^2y^4)^3 : 3^3x^6y^1^2[/tex]

= [tex]\frac{3^3x^6y^{12}}{3x^5y^{15}}[/tex]

[tex]\frac{3^{3} }{2} = 3^{2}[/tex]

= [tex]\frac{3^2x^6y^{12}}{x^5y^{15}}[/tex]

= [tex]\frac{x^{6} }{x^{5} } : x[/tex]

= [tex]\frac{3^2xy^{12}}{y^{15}}[/tex]

=  [tex]\frac{y^{12} }{y^{15} } : \frac{1}{3{y} }[/tex]

= [tex]\frac{3^2x}{y^3}[/tex]

[tex]3^2=9[/tex]

= [tex]\frac{9x}{y^3}[/tex]

Answer: 7+3/4x >= 31

Answer:

50,000

Step-by-step explanation:

The little 5 is called an exponent, so it would be 0.5*10^5.

Ten to the fifth power. you can take the ten and do this. 10x10x10x10x10. The answer would be fifty thousand

Answer:

$140

Step-by-step explanation:

100/116×$162.40=$140

Answer:

Before the increase it was $136.416.

Step-by-step explanation:

16% of $162.40 is 25.984.

We need to do $162.40 - 25.984 which equals to $136.416.
