Answer:

The length of the line segment: 5.8 units

Step-by-step explanation:

To find the length of a line segment, you must us the formula:

D=[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

1. well, you must first identify your coordinates

Point A is (-2, -4) which is ([tex]x_1[/tex], [tex]y_1[/tex])

Point B is (1, 1) which is ([tex]x_2[/tex], [tex]y_2[/tex])

2. Now you put these coordinates into your equation

D=[tex]\sqrt{(1--2)^2+(1--4)^2}[/tex]

Ofc, you gotta keep in mind of any double negatives

D=[tex]\sqrt{(1+2)^2+(1+4)^2}[/tex]

3. simplify

D=[tex]\sqrt{(3)^2+(5)^2}[/tex]

D=[tex]\sqrt{9+25}[/tex]

D=[tex]\sqrt{34}[/tex]

The square root of 34 is 5.83095189.... in decimal form

4. Round it to the nearest tenth

5.83 and since 3 is lower than five, it does nothing

5.8= The length of your line segment!

Answer:

125/343

Step-by-step explanation:

Answer:Jacob could compare the unit rates of cost per ounce. The unit rate that is less per ounce is the better deal. Not He can look at the cost per ounces!

Im late but hope this helps anyone doing makeup work!

Brand A costs $0.37 or 37 cents per ounce and Brand B costs $0.31 or 31 cents per ounce.

We need to find the unit rate for each brand. Round to the nearest cent (hundredth).

The definition of an ounce is 1/16 of a pound or a very small amount of something.

According to column 1, 8 ounces of tomatoes would cost 2 dollars and 99 cents. So, the cost of one ounce of tomatoes can be calculated as follows.

When the cost of one ounce of tomatoes is rounded off to the nearest cent, it can be written as $0.37.

According to column 2, 16 ounces of tomatoes would cost 4 dollars and 99 cents. So, the cost of one ounce of tomatoes can be calculated as follows.

When the cost of one ounce of tomatoes is rounded off to the nearest cent, it can be written as $0.31.

Therefore, Brand A costs $0.37 or 37 cents per ounce and Brand B costs $0.31 or 31 cents per ounce.

Answer:

[tex]C(x,y) = (\frac{10}{4},\frac{-1}{4})[/tex]

Step-by-step explanation:

Given

[tex]A(x_1,y_1) = (2,-1)[/tex]

[tex]B(x_2,y_2) = (4,2)[/tex]

Required

Partition = 1:3

Here, we'll make use of the following formula:

[tex]C(x,y) = (\frac{nx_1 + mx_2}{m + n},\frac{ny_1 + my_2}{m + n})[/tex]

Where

[tex]m:n = 1:3[/tex]

Substitute values for m,n,x1,x2,y1 and y2

[tex]C(x,y) = (\frac{3 * 2 + 1 * 4}{1 + 3},\frac{3 * -1 + 1 * 2}{1 + 3})[/tex]

[tex]C(x,y) = (\frac{10}{4},\frac{-1}{4})[/tex]

Area = side squared

625 = side squared

side = sqrt 625

side = 25 m

perimeter = 4 x side

perimeter = 100 m

Answer:

100 meters

Step-by-step explanation:

In order to calculate the perimeter, we must have the side length.

The area of a square can be found using the following formula.

[tex]a=s^2[/tex]

We know the area is 625 square meters. We can substitute 625 m² in for a.

[tex]625 m^2=s^2[/tex]

We want to find the side length, s. Therefore, we must isolate s. s is being squared. The inverse of a square is a square root. Take the square root of both sides of the equation.

[tex]\sqrt{625m^2}=\sqrt{s^2}[/tex]

[tex]\sqrt{625m^2}=s[/tex]

[tex]25 m=s[/tex]

The perimeter of the square can be found using the following formula.

[tex]p=4s[/tex]

We know the side length is 25 meters. We can substitute 25 m in for s.

[tex]p =4*25m[/tex]

Multiply.

[tex]p=100m[/tex]

The perimeter of the field is 100 meters.

Answer:

18 gallons

Step-by-step explanation:

From the information given, first you  have to find the amount of cans that were bought and the total amount of fluid ounces:

8 cases of soda*24 cans= 192 cans

 1 can      →   12 fluid ounces

192 cans  →                x

x= 2,304 fluid ounces

Now, you have to find the amount of gallons that you purchased considering that there are 128 fluid ounces in 1 gallon:

1 gallon  →  128 fluid ounces

     x       ←  2,304 fluid ounces      

x=(2,304*1)/128= 18 gallons

According to this, the answer is that you purchased 18 gallons.

Answer:

678

Step-by-step explanation:

250 + 23 (20 - 1 )

Replace the n with 20 Bc n is the number of bikes

250 + 23 (20 - 1 )

Do the parentheses

250 + 23 (19)

Multiply the 23 by 19

250 + 437

Add both numbers

The required weight of the 20 bikes in the container is 687 pounds.

An expression regarding relative weight between the bike-containing container is given 250+23(n−1), where n represents the number of bikes and the whole equation gives the cumulative weight of the bikes.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The given expression is 250+23(n−1),
Now, put n  = 20 According to the question,
Wight  = 250 + 23 (20 - 1)
Weight = 250 + 23 * 19
Weight = 687.

Thus, the required weight of the 20 bikes in the container is 687 pounds.

Answer:

$5.25

Step-by-step explanation:

To find the percentage of something, we can simply multiply it by its decimal equivalent. 15% means that it is 15/100 of the bill, because percent is out of 100, and 100% of it, is just the original ($35). To convert to a decimal we divide 15 by 100, which gives u: 0.15

It is still 15%, it is just now out of 1.

1 is 100%, which makes sense because 35x1=35

So, to find %15, we can do 35x0.15=5.25

Sue left a tip of $5.25

Alternatively, (but ultimately the same method), you can start by dividing 35 by 100 to get 1%. 35/100=0.35, 0.35 is 1% of 0.35

And then just multiply that 1% by 15 to get 15%

0.35 (the 1%) x 15 = 5.25 (15%)

Answer:

Step-by-step explanation:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d=\sqrt{(6+8)^2+(-1+2)^2}=\sqrt{14^2+1^2}=\sqrt{197}=14.035668...\approx14.04[/tex]

The distance is 14.03.

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. To derive the formula, let us consider two points in 2D plane A(x1,y1), and B(x2,y2).

Assume that 'd' is the distance between A and B.

d= √(x2 - x1)² + ( y2 - y1)²

Given coordinates:

(-8,-2)  and (6,-1)

Using distance formula,

=√(6+8)² + ( -1 +2)²

=√14²+1²

=√196+1

=√197

= 14.0356

≈14.03

Answer:

Answer: [tex]x=3/5[/tex]

Simplify both sides of the equation

[tex](2x+4x)=x+3[/tex] (Combine Like Terms)

[tex]6x=x+3[/tex]

Subtract x from both sides

Answer:

x = - 9, x = 2

Step-by-step explanation:

Given

(x + 9)(x + 2) = 4(x + 9) ← expand factors on left using FOIL

x² + 11x + 18 = 4x + 36 ( subtract 4x + 36 from both sides )

x² + 7x - 18 = 0 ← in standard form

(x + 9)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x - 2 = 0 ⇒ x = 2

Answer:

0.5%

Step-by-step explanation:

The prevalence rate shows the proportion of people that have a disease in a population and to be able to calculate it, you have to divide the number of people that have a disease by the population:

Prevalence rate=(5/1,000)*100

Prevalence rate=0.005*100

Prevalence rate=0.5%

According to this, the answer is that if there are five cases of H1N1 in the community of 1,000 people, the prevalence rate is 0.5%.
