Answer:

4000 gm

Step-by-step explanation:

We can use ratios to solve

Change 8 m to cm

8m * 100cm/1m = 800 cm

6 cm             800 cm

-------------  = ------------

30 grams      x gm

Using cross products

6 * x = 800 * 30

6x = 24000

Divide by 6

6x/6 = 24000/6

x = 4000 gm

Answer:

f(-5) = 19

Step-by-step explanation:

f(t) = -3t+4

Let f(t) = 19

19 =  -3t+4

Subtract 4 from each side

19 - 4 =-3t+4-4

15 = -3t

Divide each side by -3

15/-3 = -3t/-3

-5 = t

Answer:

the answer is -5

Step-by-step explanation:

F(t)=-3(t)+4

it told you that F(t) is equal to 19

so -3*-5=15+4=19

Answer:

see explanation

Step-by-step explanation:

For the triangle to be isosceles it must have 2 equal sides.

Calculate the length of the sides using the distance formula

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

with (x₁, y₁ ) = A (- 1, 2) and (x₂, y₂ ) = B (3, 5)

AB = [tex]\sqrt{(3-(-1))^2+(5-2)^2}[/tex]

     = [tex]\sqrt{(3+1)^2+3^2}[/tex]

     = [tex]\sqrt{4^2+9}[/tex]

     = [tex]\sqrt{16+9}[/tex] = [tex]\sqrt{25}[/tex] = 5

Repeat with (x₁, y₁ ) = A (- 1, 2) and (x₂, y₂ ) = C (3, - 1)

AC = [tex]\sqrt{(3+1)^2+(-1-2)^2}[/tex]

      = [tex]\sqrt{4^2+(-3)^2}[/tex]

      = [tex]\sqrt{16+9}[/tex] = [tex]\sqrt{25}[/tex] = 5

Consider B (3, 5) and C (3, - 1)

Since both x- coordinates are 3, this is a vertical line and its length is the difference of the y- coordinates, that is

BC = | - 1 - 5 | = | - 6 | = 6

Then

AB = AC = 5 , BC = 6

Since AB = AC = 5 then the triangle is isosceles

Answer:

FALSE

Step-by-step explanation:

Use the Pythagorean theorem to check.

4²+3²=6² ?

16+9=36?

The coordinates of the image of J (−5, −1) after the translation (x, y) → (x − 2, y) will be (−7, −1). Then the correct option is D.

A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.

The rule of the translation is given below.

(x, y) → (x − 2, y)

The coordinates of the image of J (−5, −1). Then the location of the point J after the translation will be

(x, y) → (x − 2, y)

(−5, −1) → (−5 −2, −1)

(−5, −1) → (−7, −1)

The coordinates of the image of J (−5, −1) after the translation (x, y) → (x − 2, y) will be (−7, −1). Then the correct option is D.

Answer:

265x{2} + 40x

Step-by-step explanation:

Squared mean to multiply the number times itself. So 15x times 15x.

[tex]15x^{2} = 225x[/tex]{2}

Then the problem says to add, but because one is squared and th other is not, they cannot be combined. So the answer is:

[tex]225x{2} + 40x

Answer:

see below

Step-by-step explanation:

15x^2 + 40x

These are not like terms so they cannot be combined.

If you mean

(15x) ^2 + 40x

(15x * 15x) + 40x

225x^2 + 40x

They are still not like terms so they cannot be combined.

Answer: 2 -(-6) = 2 + 6 = 8

* (+) - (-) = (+)

If helpful, brainliest please !

Answer and Step-by-step explanation:

If you're confused by what this expression means by looking at it, then try writing or saying out loud the expression.

Two minus negative 6. (2 - (-6))

We know from math that when two negative numbers multiply together, they result in a positive.

We have here the negative 1 (represented as just -, because it isn't necessary to include 1 in the expression) multiply the negative 6.

-1 * -6 = +6.

Now we have the expression 2 + 6.

Add them together.

2 + 6 =

8

8 is the answer.

Answer:

  15 sodas will give a maximum profit of 83

Step-by-step explanation:

For quadratic ax^2 +bx +c, the maximum occurs at x = -b/(2a). Here, we have ...

  a = -1/3, b = 10

  x = -b/(2a) = -10/(2(-1/3)) = 15

The profit for sale of 15 sodas is ...

  P(15) = (-1/3s +10)s +8 = (-1/3(15) +10)(15) +8 = 5(15) +8 = 83

The company would earn a maximum of 83 from sale of 15 sodas.

LOVE and CARING for each other

Step-by-step explanation:

Answer:

[tex] \frac{ay}{x} - dx = wx [/tex]

multiply x through out:

[tex]ay - {dx}^{2} = w {x}^{2} \\ {wx}^{2} + {dx}^{2} = ay[/tex]

factorise out x²:

[tex] {x}^{2} (w + d) = ay \\ {x}^{2} = \frac{ay}{w + d} [/tex]

take square root on both sides:

[tex] \sqrt{ {x}^{2} } = \sqrt{ \frac{ay}{w + d} } \\ \\ x = \sqrt{ \frac{ay}{w + d} } [/tex]

Step-by-step explanation:

the biggest obstacle is usually a division by x.

so, let's get rid of it by multiplying both sides of the equation by x

ay - dx² = wx²

then

ay = wx² + dx² = (w+d)x²

y = (w+d)x²/a = x² × (w+d)/a
