The percent did monthly rent increase from last year to this year is 17.6%

Last year Justine paid $680 in rent while this year she paid $800 in rent

The increase in rent = $800 - $680 = $120

The percentage increase in rent = ($120/$680) * 100% = 17.6%

The percent did monthly rent increase from last year to this year is 17.6%

Answer: 600 - 12w

Step-by-step explanation:

From the question, we are informed that a fish tank contains 600 gallons of water when full and that the tank

contains a permanent hole, which causes the tank to leak at a constant rate of 12 gallons each week.

If the number of weeks is represented by w, then the expression that describe the number of gallons left in the tank after any given number of weeks will be:

= 600 - 12w

For example let's say the number of weeks is 5 weeks. Using the expression,

600 - 12w

= 600 - 12(5)

= 600 - 60

= 540 gallons

There'll be 540 gallons after 5 weeks.

Answer:

r=v + [tex]\frac{s}{2}[/tex]

Step-by-step explanation:

v=r-[tex]\frac{s}{2}[/tex]

v+[tex]\frac{s}{2}[/tex]=r

On solving for r, we get -

[tex]$r=v+\frac{s}{2}[/tex]

We have the following expression -

[tex]$v=r-\frac{s}{2}[/tex]

We have to solve for r.

log ( [tex]\frac{\pi }{x}[/tex] ) = k

On solving -

log(π) - log(x) = k

log(x) = k - log(π)

log(x) = 2 - log(π)

log(x) = 2 - 0.497

log(x) = 1.503

x = 31.84

According to the question, we have -

[tex]$v=r-\frac{s}{2}[/tex]

On solving for r, we get -

[tex]$r=v+\frac{s}{2}[/tex]

Hence, we get - [tex]$r=v+\frac{s}{2}[/tex].

Answer:

B. Second

Step-by-step explanation:

Levers are defined as the simple machine, which consists of a rod fixed at a pivot, load, and fulcrum. The levers are classified into first class, second, and third class.

A lever is a simple machine made of a rigid beam and a fulcrum. The effort (input force) and load (output force) are applied to either end of the beam. The fulcrum is the point on which the beam pivots. When an effort is applied to one end of the lever, a load is applied at the other end of the lever.

here, we have,

The difference between different types of levers are:

1. In the first-class levers, the fulcrum is present between the load and effort. The mechanical advantage can be greater, less, or equal to 1.

2. The second class levers, the load is present between the fulcrum and effort. The mechanical advantage is always greater than the 1.  

3. The third class levers, the effort is present between the fulcrum and load. The mechanical advantage is always less than 1.  

Thus, the correct answer is Option 1.

Answer: If half a gallon is 15 then just multiply 15 with 2.

Step-by-step explanation:

Answer:

He drove 27[tex]\frac{13}{31}[/tex] miles per gallon.

Step-by-step explanation:

15[tex]\frac{1}{2}[/tex] gas = 425 miles

[tex]\frac{31}{2}[/tex] gas = 425 miles

31 gas = 425 × 2

          = 850 miles

1 gallon = 850 miles ÷ 31

1 gallon = 27[tex]\frac{13}{31}[/tex] miles

Answer:

B. x = -8

Step-by-step explanation:

-4(2x + 3) = 2x + 6 - (8x + 2)

-8x -12 = 2x + 6 - 8x -2

(now, "-8" in both terms is cancelled):

-12 = 2x + 6 - 2

(leave 2x alone in second term):

-12 -6 +2 = 2x

-16 = 2x

-16/2 = x

-8 = x

Answer:

Distance between home plate and second base = 127.3 ft (Approx)

Step-by-step explanation:

Given:

Base distance = 90 ft

Find:

Distance between home plate and second base

Computation:

Distance between home plate and second base = √90²+90²

Distance between home plate and second base = √8100 + 8100

Distance between home plate and second base = √16200

Distance between home plate and second base = 127.3 ft (Approx)

Answer:

The value of x that makes both functions. y = 4·x + 6 and y = 5·x + 3 equal is;

x = 3

Step-by-step explanation:

The given functions are;

y = 4·x + 6 and y = 5·x + 3

For the functions to be equal, we have that the y values are equal, therefore;

y = y and 4·x + 6 = 5·x + 3, which gives;

4·x + 6 = 5·x + 3

5·x - 4·x = 6 - 3

∴ x = 3

Therefore, the value of x that makes both functions. y = 4·x + 6 and y = 5·x + 3 equal is x = 3.

Answer:

b = -12

Step-by-step explanation:

In order to find the slope intercept you must first find the slope of the given points.

[tex]-4,2 = 12,6[/tex]

[tex]S=\frac{y2-y1}{x2-x1}[/tex]

Substitute:

[tex]\frac{12--4}{6-2}[/tex]

[tex]12--4=12+4=16[/tex]

[tex]6-2=4[/tex]

[tex]S=\frac{16}{4}[/tex]

Now find the slope intercept

[tex]16\div4=4[/tex]

[tex]SI=y=mx+b[/tex]

Substitute:

[tex]12=4\times6+b[/tex]

Solve:

[tex]4\times6=24[/tex]

[tex]12=24+b[/tex]

Subtract 24 on both sides:

[tex]12-24=-12[/tex]

[tex]x=-12[/tex]

[tex]y=-12[/tex]

Hope this helps.
