Answer: Ben can only rent the boat for 5 hours.

Step-by-step explanation:

You have to set up an equation. It would be 20 + 12h = 80

20+12x=80

12x=80-20

Then divide both sides 12x=60

And you get 5

Answer:

x = -4

Step-by-step explanation:

let x equal the number

so

1/4(-x)+2=1/2(-x)+4

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

+1/2x          +1/2x

1/2x + 2 = 4

        -2    -2

1/2x = 2

x = -4

Answer: x=-8

Step-by-step explanation:

1/4x+2=2x+16

Multiply by four to get rid of the fractions

X+8=2x+16

Combine like terms

-x=8

x=-8

Answer:

2?

Step-by-step explanation:

i think its 2 because 1 is an odd number and it goes 1,1 ( two odd numbers) then __ 3,5 ( two more odd numbers then 8,13,21( even number then two more odd numbers) the 34( even number). i'm thinking the pattern is odd, odd, even, odd, odd, even, odd odd, even.

Answer:

Step-by-step explanation:

Answer:

FOR THE FIRST ONE : 36.4

FOR THE SECOND : 18.9

FOR THE THIRD : X*(0.30)

Step-by-step explanation:

IN THE FIRST EXAMPLE I MULTIPLIED THE NUMBER BY 0.30 AND THEN ADDED THE NUMBER TO THE MAIN NUMBER

IN THE SECOND I MADE THE SAME BUT I SUBTRACTED INSTAID

IN THE THIRD I WILL MULTIPLY X BY 0.30 AND THEN SUBTRACT THE NUMBER FROM THE VALUE OF X

Answer:

length 4.96 cm(4 24/25) Width 1.80 cm( 1 8/10 cm)

Step-by-step explanation:

If the perimeter is 15 1/3 cm and the length is 3 1/6 cm longer than the width. Then first you have to take away 6 1/8. How did I get that? Because since a rectangle has 2 sides of length and 2 sides of width, I added 3 1/6+3 1/6. When we subtract the whole number you get 7. And when you subtract the fractions you get 5/24. I got that by doing 1/3x8  and 1/8x3. So i get a deminitor of 24. Then you have to divide 7 5/24 into 4 parts, since there is four sides. Which then you get ~1.80. That means the width is abut 1.80. And if you add the 3 1/6 back on the length it will be about 4.96.

Answer:

option 3 , 12

Step-by-step explanation:

Answer:

Step-by-step explanation:

f(n)=30n

domain all real numbers

range all real numbers

I think.

Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.

A relation is a function if it has only One y-value for each x-value.

The function that relates the total number of minutes practiced, p, to the number of practice days, n, is given by:

p = 30n

where 30 is the number of minutes Elena practices each day.

Since we cannot have negative practice days, the domain of the function is the set of non-negative integers:

Domain: {0, 1, 2, 3, ...}

The range of this function is the set of all possible values of p that can be obtained by plugging in values of n from the domain.

In this case, since the function only outputs non-negative values, the range is the set of non-negative integers:

Range: {0, 30, 60, 90, ...}

Hence, Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.

Answer:

C.)

Step-by-step explanation:

Add the area if the rectangle, to the area of the two semi-circles.

Area of Rectangle: L: 6[tex]\frac{5}{8}[/tex] in times W: 8 in = 53 in

Area of Semi-circle: [tex]\frac{1}{2}[/tex](πr2): [tex]\frac{1}{2}[/tex](π(4)2) = 25.13  

(r is always half of diameter (d) so r=4)

53 + 25.13 + 25.13 = 103.26
