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

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%

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.

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

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

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.

The fastest elevators in the Burj Khalifa can travel 330 feet in just 10 seconds. How far does the
elevator travel in 11 seconds? Explain your reasoning.

Answers

Answer:

363 feet = 11 seconds

Step-by-step explanation:

330 feet = 10 seconds

=> 330/10 feet = 10/10 seconds

=> 33 feet = 1 second

=> 33 × 11 feet = 11 × 1 second

=> 363 feet = 11 seconds.

Therefore, the Burj Khalifa can travel 363 feet in 11 seconds.

Answer:

[tex]363ft[/tex]

Step-by-step explanation:

First we know that the elevator can travel 330 feet  in just 10 seconds. That's can be interpret as:

[tex]\frac{330ft}{10s} = \frac{33ft}{1s}[/tex]

How you can see each second the elevator travel 33 feet so if you want to know how many travel in 11 second you only have to multiply by 11 the 33ft.

[tex]33ft \cdot 11s = 363ft[/tex]

Points C open parentheses negative 5 comma 8 close parentheses and D open parentheses 2 comma 5 close parentheses lie on line C D. If points C apostrophe and D apostrophe are created by translating points C and D left 6 units, what is the slope of line C apostrophe D apostrophe ?

Answers

We want to find the slope of the line that connects points C' and D'. We will find that the slope is -3/7.

First, we start with the points:

C = (-5, 8)D = (2, 5)

Now we create points C' and D' by translating points C and D to the left by 6 units, this means that we need to subtract 6 in the x-value of each point, so we will have:

C' = (-5, 8) + (-6, 0) = (-5 - 6, 8) = (-11, 8)D' = (2, 5) + (-6, 0) = (2 - 6, 5) = (-4, 5)

And we know that if a line passes through points (x₁, y₁) and (x₂, y₂) the slope is given by:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Then the slope that connects points C' and D' is:

[tex]a = \frac{5 - 8}{2 - (-5)} = \frac{-3}{7}[/tex]
