if i have 1000 dollars and lose 1000 dollars how much do i have left 100 points

Answer:

20 shirts

Step-by-step explanation:

We are told she paid 80 dollars for general supplies. It costs her 2 dollars to make each t shirt.

Total cost of production is;

80 + 2t

Where t is number of t-shirts.

We are told that She charges 6 dollars per shirt.

This means that total revenue from sales is; 6t

Now,in economics or business, break even point is the point where revenue and total cost are equal.

Thus, break even point will be at;

80 + 2t = 6t

6t - 2t = 80

4t = 80

t = 80/4

t = 20 shirts

8-4=4

if every 2 years, 4 gallons disappear

then every 1 year, 2 gallons disappear

meaning that by 5 years there will be no substance left.

Answer:

V = 2000 km/h

Step-by-step explanation:

Recall that you need to follow proportionality here, and the ratio involved is: 10 km / 1 cm

then if the vector is 2 m long, then it is 200 cm long (converting it from meters to the same units as our scale which is in cm)

then we have to solve the following proportion to obtain the velocity "V":

10 km/h / 1 cm = V / 200 cm

multiply both sides by 200 to solve for V:

V = 2000 km/h

Answer: He will need  8.4 liters to conver 7 m².

Step-by-step explanation:

1. You have that 1 m² is convered with 1.2 liters of paint.  

2. Therefore, to solve this problem, you can calculate the liters needed to cover 7 m² by multiplying this area by 1.2 liters and dividing this by 1 m².

Step-by-step explanation:

The question is not complete, the complete question is:

A rectangle is constructed with its base on the x-axis and two of its vertices on the parabola y 81-x², what are the dimensions of the rectangle with the maximum area? what is the area?

Solution:

Given the parabola:

y = 81 - x²

Let the points (a,0) and (-a, 0) be points on the axis, this points touch the parabola at (a, 81 - a²) and (-a, 81 - a²).

Points (a,0), (-a, 0), (a, 81 - a²), (-a, 81 - a²) form the rectangle.

The length of rectangle = distance between (a,0) and (-a, 0) or between (a, 81 - a²) and (-a, 81 - a²) = 2a

The breadth of rectangle = distance between (a,0) and (a, 81 - a²) or between (-a, 0) and (-a, 81 - a²) = 81 - a²

Area of rectangle (A) = length × breadth = 2a × (81 - a²) = 162a - 2a³

A = 162a - 2a³

The maximum area is at dA / da = 0

dA / da = 162 - 8a² = 0

162 - 6a² = 0

6a² = 162

a² = 27

a = 5.2 units

Length = 2a = 2(5.2) =  10.4 units

Breadth = 81 - a² = 81 - 5.2² = 54 unit

Area = length × breadth = 54 × 10.4 = 561 unit²

18. -3

19. 11/-6

20. 0

Step-by-step explanation:

Im not explaining for each cause that would take too long, just know you plug in the y and x into the formula y1-y2/x1-x2. So for the first one, you would have -1--1 / 4--2 but when there are two subtractions signs it turns into a plus so -1+1 / 4+2

Answer:

Recursive formula is: [tex]a_1=-1 ; \ \ a_n=a_{n-1}+7[/tex]

Explicit formula is: [tex]a_n=7n-8[/tex]

Step-by-step explanation:

We need to find recursive formula and explicit formula for arithmetic sequence -1,6,13,20,27

In the given sequence First term a₁= -1

Common difference d = 7

Finding Recursive Formula

The recursive formula is of type:[tex]a_1= First \ term[/tex] and [tex]a_n=a_{n-1}+d[/tex]

Since the First term a₁ is -1 and common difference d is 7 so, the recursive formula  for given arithmetic sequence will be:

[tex]a_1=-1 ; \ \ a_n=a_{n-1}+7[/tex]

Finding Explicit Formula

The explicit formula is of type: [tex]a_n=a_1+(n-1)d[/tex]

We have

First term a₁= -1

Common difference d = 7

So, explicit formula will be:

[tex]a_n=-1+(n-1)7\\a_n=-1+7n-7\\a_n=7n-8[/tex]

So, explicit formula is: [tex]a_n=7n-8[/tex]

Answer:

2.5

Step-by-step explanation:

The length of Priya’s run was 2.5 times Tyler’s run.

Given

Priya ran 1 1/2 miles today, and Tyler ran 3 3/4 miles.

To determine how many times the length of Priya’s run was Tyler’s run following all the steps given below.

Let, the distance covered by Priya be x and Tyler be y.

Priya ran 1 1/2 miles today.

Then,

[tex]\rm = 1 \dfrac{1}{2}\times x\\\\= \dfrac{2\times 1+1}{2}\times x\\\\= \dfrac{2+1}{2}\times x\\\\=\dfrac{3x}{2}[/tex]

Tyler ran 3 3/4 miles.

[tex]\rm = 3 \dfrac{3}{4}\times y\\\\= \dfrac{4\times 3+3}{4} \times y\\\\= \dfrac{12+3}{4} \times y\\\\= \dfrac{15y}{4}[/tex]

On comparing both the distance

[tex]\rm \dfrac{3}{2} \times x= \dfrac{15}{4}\times y\\\\x = \dfrac{5y}{2} \\\\x = 2.5y[/tex]

Hence, the length of Priya’s run was 2.5 times Tyler’s run.

Answer:

RIP to all those kings!!

Step-by-step explanation:

Answer:

28

Step-by-step explanation:

let the missing number be x

x÷2+49=2¼x

49=9/4x-x/2

lcm=4

9x-2x/4

49=7x/4

49×4=7x

196=7x

divide both sides by 7

196/7=x

therefore 28=x
