Answer:

10 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (5, 2) and (x₂, y₂ ) = (- 3, - 4)

d = [tex]\sqrt{(-3-5)^2+(-4-2)^2}[/tex]

  = [tex]\sqrt{(-8)^2+(-6)^2}[/tex]

  = [tex]\sqrt{64+36}[/tex]

   = [tex]\sqrt{100}[/tex]

    = 10

Answer:

12 years

Step-by-step explanation:

Represent the mother's age by m and the son's by 4.  Currently m = 36 years old.

In x years the mother will be three times as old as her son:

mother:  36 + x years old

son:  4 + x years old

The pertinent equation to solve is:

36 + x = 3(4 + x)

Performing the multiplication, we get:

36 + x = 12 + 3x, or

24 = 2x.  Then x = 12.

Check:  In 12 years, will the mother's age be 3 times the son's age?

Does 36 + 12 = 3(4 + 12)?

Does    48      = 48?  YES

The mother will be 3 times as old as her son in 12 years from now.

Answer:

isosceles right triangle

Step-by-step explanation:

In this question it is given that the two sides of easel are same.

A triangle formed has three sides - two of easel and one of the table itself.

The angle formed in 90 degrees (right angle)

Hence the triangle is a isosceles right triangle

Answer:

(5y - 1)(5y + 1)

Step-by-step explanation:

Assuming you require the expression to be factorised.

25y² - 1 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

25y² - 1

= (5y)² - 1²

= (5y - 1)(5y + 1)

Answer:

Below.

Step-by-step explanation:

25y²-1

This is the difference of 2 squares and it factors to (5y - 1)(5y + 1).

Answer:  C. 3

-6v<   x       v>-.5

divide by -6  flips the inequality

v> x/-6

so x/-6 = -.5

multiply by -6 on each side

x = -.5 * -6

x=3

Answer:

1) Sam makes 48 pizzas in 8 hours. Sam makes 6 pizzas per hour.

2) The machine makes 1.8 copies per second.

3) 10 pens cost $9.00

4) $0.28

Step-by-step explanation:

1)

[tex]\frac{15}{2.5} =\frac{x}{8} \\\\2.5x=120\\x=48[/tex]

[tex]\frac{15}{2.5} =\frac{x}{1} \\\\2.5x=15\\x=6[/tex]

2)

[tex]\frac{45}{25} =\frac{x}{1} \\\\25x=45\\x=1.8[/tex]

3)

[tex]\frac{3}{2.7} =\frac{10}{x} \\\\3x=27\\x=9[/tex]

4)

2.8/10 = 0.28

Answer:

30

Step-by-step explanation:

Let the amount of money Taylor spent = x

The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans.

Hence

1/5 × x = 6 jeans

x/5 = 6 jeans

Cross Multiply

x = 5 × 6 jeans

x = 30

The amount of money Taylor spent = 30

Answer: 6/4x

Then  John ended up with  v/4  magnets  and  gave away  (3/4)x

Liam   gave  away  2 ( 3/4)x = 6/4x  magnets  and  was  left  with  x/4  magnets

Notice that they have the same number now so  John  has 100%  of Liam's  magnets

Answer:

(x + 4)^2 + (y – 9)^2 = 25

Step-by-step explanation:

The standard form for a circle is

[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex]     where (h, k) is the center and r is the radius

In your case, h = -4 and k = 9 and r = 5

So, (x + 4)^2 + (y – 9)^2 = 25

The equation for this circle is given as

[tex](x+4)^2 + (y-9)^2 = 25[/tex]

Data

The equation of circle is given by

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

Let's substitute our values and get our equation

[tex](x--4)^2 + (y-9)^2 = 5^2\\(x+4)^2 + (y-9)^2 = 25[/tex]

we substituted the values of h and k and made sure it's in the standard form of equation of a circle.

The equation for this circle is given as

[tex](x+4)^2 + (y-9)^2 = 25[/tex]

This looks exactly like

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

Answer:

The 3rd one 2.15

Step-by-step explanation:

12.35 in whole

1.25 x 3 = 3.75

12.35-3.75= 8.60

[tex]\sqrt[4]{8.60}[/tex] = 2.15

pls give brainlist <33

Answer:

$2.15

Step-by-step explanation:

Start off by multiplying $1.25 by 3 to find out how much the burgers are all together. This would be $3.75 for all three of the burgers. Then subtract $3.75 from the total amount spent ($12.35). This would give you $8.60. To find how much he spend on each corndog, you do $8.60 divided by 4. This would give you the answer of $2.15.
