You would simply divide 14 by 6 which gives you 2.3 repeating and 0.3 repeating is the fraction 1/3.

Answer:

6.15 miles

Step-by-step explanation:

Step one:

given data

Nicole ran 3 2/5 miles and

Ana ran 2 3/4 miles on Saturday

Required:

The total distance covered by both friends

Step two:

total distance= 3 2/5 + 2 3/4

let us convert the mixed fraction to a simple fraction

=17/5+11/4

=68+55/20

=123/20 miles

or

=6.15 miles

Answer:

Choice C. quarts

Step-by-step explanation:

In one gallon there is 8 pints, 16 cups, and 4 quarts. So if the proportion was set up like this [tex]\frac{1gallon}{4quarts}*\frac{3gallons}{xquarts}[/tex] it's likely that they are looking for how many quarts are in 3 gallons, and since we now know that 4 quarts is one gallon we can multiply 3 and 4 to get 12. So in 3 gallons there's 12 quarts.

-70

Step-by-step explanation:

just use a calculator my g

Answer-70

Step-by-step explanation:

-100 plus 50 = -50 then you add -20 making it -70

Answer:

Step-by-step explanation:

First, start out with the parent function:

[tex]y = b^{x}[/tex]

Now, we look at the transformations, and make the equation.

We see that the graph shifted down 4 units, since the graph's horizontal asymptote is at y = -4.

[tex]y = b^{x} - 4[/tex]

We see point (0, -3) to point (1, -1). The value of b would be 3. The reason is that when you plug 0 in, you get 1, then 1 - 4 equals 3. (0, -3),

Then, when you plug in 1, you get 3, then 3 - 4 equals -1. This matches up with the graph.

This is the answer:

[tex]y = 3^{x}-4[/tex]

Answer:

So x can have values from zero to 449

Step-by-step explanation:

0.40 X plus 20 < 200

0.4x +20 < 200

Putting the values of x for 0,1,2,

0.4x +20 < 200

0.4(0) +20 < 200

20< 200

0.4x +20 < 200

0.4(1) +20 < 200

20.4 <200

0.4(2) +20 < 200

20.8 <200

The maximum value which x can have is less than 450 because 450 would give a number equal to 200 and we have the inequality of a number being less than 200

0.4x +20 < 200

0.4(450) +20 < 200

180+20<  200

200 <20  which is wrong.

So x can have values from zero to 449

0.4x +20 < 200

0.4(449) +20 < 200

179.6+20<  200

199.6 <200  

X  can have the values fom 0 to 449.

Answer:

- 4 3/20 The other person is correct

Step-by-step explanation:

The water is 399 feet fell.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Two years ago, the water level in a local reservoir fell 834 feet.

Last year, the water level rose 435 feet.

So, the water level of the reservoir change overall during these two years

= -834 + 435

= -399

Hence, the water is 399 feet fell.

I believe the first one but I'm not 100% sure.

Answer:

X=10, Y=4

Step-by-step explanation:

Along the y-axis, x = 0.

2(0) + 5y = 20

5y = 20

y = 4

Your y-intercept is at (0,4).

Along the x-axis, y = 0

2x + 5(0) = 20

2x = 20

x = 10

Your x-intercept is at (10,0).

Answer:

-2x-5y=20 (if x= 2 )

[tex] - 2 \times 5 - 5 \times y = 20 [/tex]

[tex] - 20 - 5 \times y = 20[/tex]

[tex] - 5 \times y = 40[/tex]

Answer: 4 workers

==============================================

Explanation:

We have 9 workers painting walls in a house. Let's say the total square feet needed to be painted is 9000 square feet. I picked some arbitrary large multiple of 9, so that it leads to 9000/9 = 1000 square feet per worker.

In other words, each worker paints 1000 square feet.

They can do the job in 48 hours, which means their rate is 1000/48 = 125/6 square feet per hour approximately.

After 8 hours, each worker paints 8*(125/6) = 500/3 square feet. So all 9 workers painted 9*(500/3) = 1500 square feet

Put another way: they got 8/48 = 1/6 of the job done after 8 hours, so (1/6)*9000 = 1500 sq feet of wall has been painted so far. This leaves 9000-1500 = 7500 sq ft unpainted.

------------------------------------------------

Let x be the number of workers that leave.

There are 9-x people still on the job.

The 7500 sq ft of left over wall is divided among the 9-x people. Each worker gets 7500/(9-x) sq feet of wall to paint.

Earlier we found each worker's rate was 125/6 sq ft per hour. If they complete the remaining job in 72 hours, then,

(rate)*(time) = (amount of job done)

(125/6)*(72) = 7500/(9-x)

1500 = 7500/(9-x)

1500(9-x) = 7500

9-x = 7500/1500

9-x = 5

-x = 5-9

-x = -4

x = 4

4 workers went home.

If 4 workers went home, then 9-4 = 5 workers remain

They each have 7500/5 = 1500 sq ft of wall to paint, which helps confirm the answer.
