In the diagram of DGF below, HE||GF, DH=6, DE=4, and EF=16. What is the
length of DG?

Answers

Step-by-step explanation:

[tex] \frac{de}{df} = \frac{dh}{dg} \\ \frac{4}{16} = \frac{6}{dg} \\ dg = \frac{6 \times 16}{4} \\ dg = 24[/tex]

the ratio of the sides of the smaller triangle vs the larger triangle is 1:5 because when the smaller triangles side is 4, the larger one is 20. We could use this information to multiply the hypotenuse of the smaller triangle by 5 to get the hypotenuse of DFG, which is 30.

if there are jelly beans in a jar: 4 green, 2 white, and 5 purple. what is the probability of choosing a white jelly bean and then a purple if you put the white jelly bean back in the jar?

Answers

Answer:

Probability of choosing a white jelly bean: 18.18181818%

Probability of choosing a purple jelly bean: 45.45454545%

Step-by-step explanation:

Part #1:

4 (green) + 2 (white) + 5 (purple) = 11 jelly beans

2 white / 11 total

probability percentage (of choosing a white jelly bean) over 100% (100% = all 11 jelly beans) is equal to 2 (white jelly beans) over 11 (11 = 100% of the jelly beans)

[in other words, 11 jelly beans is 100%]

#1: unknown/100% = 2/11

#2: divide 2 by 11 (2/11 = 0.1818181818)

#3: multiply both sides by 100 (0.1818181818 * 100 = 18.18181818%)

Probability of choosing a white jelly bean: 18.18181818%

Part #2:

4 (green) + 2 (white) + 5 (purple) = 11 jelly beans

5 purple / 11 total

probability percentage (of choosing a purple jelly bean) over 100% (100% = all 11 jelly beans) is equal to 5 (purple jelly beans) over 11 (11 = 100% of the jelly beans)

[in other words, 11 jelly beans is 100%]

#1: unknown/100% = 5/11

#2: divide 5 by 11 (5/11 = 0.4545454545)

#3: mulitply both sides by 100 (0.4545454545 * 100 = 45.45454545%)

Probability of choosing a purple jelly bean: 45.45454545%

y^2 − 20x − 6y − 51 = 0

Answers

answer:

Simplifying Y2 + -20X + -6y + -51 = 0

Reorder the terms: -51 + -20X + Y2 + -6y = 0

Solving -51 + -20X + Y2 + -6y = 0

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '51' to each side of the equation. -51 + -20X + Y2 + 51 + -6y = 0 + 51

Reorder the terms: -51 + 51 + -20X + Y2 + -6y = 0 + 51 Combine like terms: -51 + 51 = 0 0 + -20X + Y2 + -6y = 0 + 51 -20X + Y2 + -6y = 0 + 51

Combine like terms: 0 + 51 = 51 -20X + Y2 + -6y = 51

Add '-1Y2' to each side of the equation. -20X + Y2 + -1Y2 + -6y = 51 + -1Y2

Combine like terms: Y2 + -1Y2 = 0 -20X + 0 + -6y = 51 + -1Y2 -20X + -6y = 51 + -1Y2 Add '6y' to each side of the equation. -20X + -6y + 6y = 51 + -1Y2 + 6y Combine like terms: -6y + 6y = 0 -20X + 0 = 51 + -1Y2 + 6y -20X = 51 + -1Y2 + 6y Divide each side by '-20'. X = -2.55 + 0.05Y2 + -0.3y Simplifying X = -2.55 + 0.05Y2 + -0.3y

Which of the following is the graph of the equation y = −2x^2 − 3x + 4?

Answers

The graph that opens down and crosses (0,4) matches the equation.
The negative two in front of the x^2 means the graph will open downwards, eliminating the option that opens upward. The +4 at the end of the equations means the graph will cross the y axis at y=4 (it has a y intercept of 4). Only 1 graph opens downward and has a y intercept of 4.

The sum of three numbers is 301. The second number is 3 less than twelve times the first number. The third number is 4 more than seven times the first number. Find the three numbers.​

Answers

Answer:

Smallest number = 15

Second number = 177

Third number =     109

Step-by-step explanation:

Givens

Let the first number = x

Let the second number = 12x - 3

Let the third number = 7x + 4

Equation

x + 12x - 3 + 7x +4 = 301                 Combine like terms

Solution

20x + 1 = 301                                  Subtract 1 from both sides

20x = 301 - 1                                  Combine

20x = 300                                      Divide by 20

x = 300/20

x = 15

What is the distance between points (6,-9) and (-3,4)

Answers

Answer:

18

Step-by-step explanation:

Distance between points (6, -9) and (-3, 4) is 15.81 units.

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

We have to given that;

Two points are (6, -9) and (-3, 4).

We know that;

Distance between two points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

Hence, Distance between two points (6, -9) and (-3, 4) is,

⇒ d = √ (- 3 - 6)² + (4 - (-9))²

      = √ (-9)² + 13²

      = √ 81 + 169

      = √250

      = 15.81
