Answer:

because a=b and c=d so bisect

Step-by-step explanation:

2s + b = 23.6

s + 4 = b

s = b - 4

2b - 8 + b = 23.6

3b = 31.6

b = 31.6 / 3 = 10.53333333(etc.) which is approx. 10.53

s = 6.53

Answer:

The correct answer is C. 6x = 500.

Step-by-step explanation:

In this expression, the "x" represents how many dollars he needs to save every month. Or in other words, the amount of money he earns a month multiplied by the amount of months should equal 500 in order for Parvinder to be able to go on his trip.

Therefore, the correct answer is C. 6x = 500.

Answer:

IM A HUGE TRAVIS SCOTT FAN I SNUCK IN ONE OF HIS CONCERTS

Step-by-step explanation:

The answer is A: Town

Given:

The graph of an inequality.

To find:

The inequality for the given graph.

Solution:

From the given graph it is clear that the related line is a vertical line parallel to the y-axis at a distance of 7 units from the left of y-axis. It intersect the x-axis at x=-7.

So, the related equation for boundary line is

[tex]x=-7[/tex]

The shaded region is on the left side of the boundary line. it means, the value of x which are less than -7 are included in the solution set.

The boundary line is a solid line. It means -7 is also included in the solution set.

The value of x is less than or equal to -7. So, the inequality for shaded region is

[tex]x\leq -7[/tex]

Therefore, the correct option is B.

Answer: 4.5 hours

Step-by-step explanation: i used cross multiplication.

2.5/x=60,000/108,000

60,000x=270,000

divide 270,000 by 60,000

x=4.5

An equation is formed when two equal expressions. The time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that the amount of time it takes a water pump to empty a tank varies directly with the capacity of the tank. Therefore, the relationship can be written as,

V ∝ T

V = kT

Substituting the volume and time in the equation,

60,000 gallons = 2.5 hours × k

Solving the equation for k,

k = 60,000 gallons / 2.5 hours

k = 24,000 gallons per hour

Now, the equation for the relationship can be written as,

V = 24,000 gallons per hour × T

Now, the time the same pump will take to empty a tank containing 108,000 gallons of water is,

V = 24,000 gallons per hour × T

108,000 gallons = 24,000 gallons per hour × T

108,000 gallons / 24,000 gallons per hour = T

T = 4.5 hours

Hence, the time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.

Answer:

Her electric toothbrush makes 210,000 rotations in one week

Step-by-step explanation:

Note that:

∵ Gerry brushes her teeth for two minutes, twice a day

→ Twice means times 2

∴ Gerry brushes her teeth for 2 × 2 = 4 minutes a day

∵ Gerry's electric toothbrush rotates the brush 125 times per second

∵ 1 minute = 60 seconds

→ Multiply 125 by 60 to find the number of rotating in 1 minute

∴ Gerry's electric toothbrush rotates 125 × 60 = 7,500 in 1 minute

∵ Gerry brushes her teeth for 4 minutes a day

→ Multiply it by 4 to find the number of rotation in 1 day

∴ Gerry's electric toothbrush rotates 7,500 × 4 = 30,000 in 1 day

∵ 1 week = 7 days

→ Multiply the number of rotation in 1 day by 7 to find it in 1 week

∴ Gerry's electric toothbrush rotates 30,000 × 7 = 210,000 in 1 week

∴ Her electric toothbrush makes 210,000 rotations in one week

55 + 65 = 120

120\2 = 60

Answer:

Please check the explanation.

Step-by-step explanation:

We know the equation

y = kx

k = y/x

where k is the proportionality constant

so,

First ratio can be calculated as

Miles = 45

Hours = 3/4

The ratio = 45 / (3/4)

                = (45 × 4) / 3

                = 180/3

                = 60

Thus, the proportionality constant = 60

Thus, the remaining ratios can be calculated as:

The Pair (135, Hours)

135/Hours = 60

Hours = 135 / 60

           = 27/12

           = 9/4

           = 2.25

Thus, the pair is (135, 2.25)

The Pair (Miles, 3)

Miles/3 = 60

Miles = 60×3

         = 180

The Pair (90, Hours)

90/Hours = 60

Hours = 90 / 60

          = 3/2

          = 1.5

Thus, the complete table:

Miles           45           135           180             90

Hours           3/4          9/4           3                 3/2

Verification:

Miles / Hour =  45/(3/4) = 60

Miles / Hour = 135 / 2.25 =  60

Miles / Hour = 180 / 3 = 60

Miles / Hour  = 90 / 1.5 =  60      

Answer:

A -> (0,-4)

B -> (3, -8)

C -> (4, 0)

Step-by-step explanation:

Hiya! When it came to this, the goal of shifting a figure across the x-axis is to get it flipped across the horizontal line. By doing this, which I may potentially be incorrect on, I assumed that you would have to take the negatives of the y values in order to make that shift downwards. I left the x-values be, as I believe they remain stable when you're only doing a reflection across the x-axis. C also remained the same, as a negative of a zero is still a zero. If you would like to see this change graphed out, I would recommend plugging the coordinates into Desmos to see the shapes. I hope this at least helped a little!

Limit x---> 3 of  f(x) = -1.

the 4 ordered pairs for the given proportional relation are (1, 7), (2, 14), (3, 21), (4, 28).

Here we know that the sloth travels about 7 feet every minute, then we can define the speed as:

S = 7 ft/min

Now remember the relation:

distance = speed*time

Then the proportional relation is:

D = 7*t

The ordered pairs are of the form (t, D)

if t = 1.

D = 7*1 = 7

if t = 2

D = 7*2 = 14

if t = 3

D = 7*3 = 21

if t = 4

D = 7*4 = 28

Then the 4 ordered pairs are (1, 7), (2, 14), (3, 21), (4, 28).

One of the solutions of the given equation y = 5x is (2,10)

The solution of an equation means if we substitute the value of this solution into the equation, it will produce the correct equality from the left side to the right side.

If the solution has 2 variables, for example x and y, and the solution is (a,b) means that if we replace x with a and y with b, the equality is correct.

The given equation is: y = 5x

For option (-2,10), substitute x = -2 and y = 10 into the equation:

10 = 5 . (-2)

10 = -10 (False)

Hence (-2,10) is not a solution.

For option (-5, 25), substitute x = -5 and y = 25 into the equation:

25 = 5 . (-5)

25 = -25 (False)

Hence (-5, 25) is not a solution.

For option (-3, 15), substitute x = -3 and y = 15 into the equation:

15 = 5 . (-3)

15 = -15 (False)

Hence (-3, 15) is not a solution.

There is no options in the problem that gives the correct equality. Looks like there is a typo.

Example of a solution of the given equation is (2,10), since if we substitute x = 2 and y = 10 into the equation:

10 = 5 . (2)

10 = 10 (True)

Hence (2, 10) is a solution.

Answer:

-6.3

Step-by-step explanation:

You can do it on calculator.

cot(θ) = cos(θ)/sin(θ)

So if both cot(θ) and cos(θ) are negative, that means sin(θ) must be positive.

Recall that

cot²(θ) + 1 = csc²(θ) = 1/sin²(θ)

so that

sin²(θ) = 1/(cot²(θ) + 1)

sin(θ) = 1 / √(cot²(θ) + 1)

Plug in cot(θ) = -2 and solve for sin(θ) :

sin(θ) = 1 / √((-2)² + 1)

sin(θ) = 1/√(5)
