The larger of two numbers is 12 more than twice the smaller. The larger number is 36. What is the smaller number?

Answers

Answer 1

Answer:

The smaller number must be 12

Step-by-step explanation:

Ignoring the second sentence we can make an expression from the question :

x is larger number

y is the smaller number

x = 2y + 12

Now we substitute 36 for x and solve for y :

36 = 2y + 12

Subtract 12 from both sides :

24 = 2y

Divide both sides by 2 :

12 = y

y = 12

The smaller number must be 12.

But let's check :

12 × 2 = 24

24 + 12 = 36

✅

Hope this helped and have a good day

The turning point of the parabola is the point (2, - 9).

What is the turning point of a quadratic equation?

Quadratic equations represents parabolae and the vertex of the parabola represents the turning point as the slope of the curve changes its sign, from positive to negative or viceversa. The vertex can be derived by the vertex form of the equation of the parabola:

y - k = C · (x - h)²

Where:

(h, k) - Coordinates of the vertex.C - Vertex constant

Since the quadratic equation has two real coefficients, we need the location of two points on Cartesian plane to find one solution. First, create the system of linear equations:

b = - 5 (1)

5 · a + b = - 25 (2)

Second, substitute b in (2) and clear a:

5 · a - 5 = - 25

5 · a = - 20

a = - 4

Third, write the quadratic equation:

y = x² - 4 · x - 5

Fourth, transform the equation into vertex form by completing the square:

y + 9 = x² - 4 · x + 4

y + 9 = (x - 2)²

Fifth, write the vertex of the parabola:

(h, k) = (2, - 9)

The point (2, - 9) represents the turning point of the parabola.

How to find the equation of a line?

The equation of a line can be represented in different form such as standard form, general form, slope intercept form and point slope form. Therefore, let's represent the line in slope intercept form.

The equation of a line in slope intercept form is as follows:

y = mx + b

where

m = slopeb = y-intercept

Parallel line shave the same slope.

Hence,

( 7,-3) , 3y = 12x + 5

y = 4x + 5 / 3

slope is 4

The equation of the line is y = 4x + b. let's find the y-intercept using (7, -3).

-3 = 4(7) + b

b = -3 - 28

b = - 31

Hence, y = 4x - 31

(-5, -2), y + 3x = 10

y = -3x + 10

slope = -3

Therefore, let's find y-intercept using (-5, -2)

-2 = -3(-5) + b

-2 = 15 + b

b = -2 -15

b = - 17

Therefore, y = -3x - 17.

total balance = $367.50

interest = $67.50

A= $367.50

I = A - P = $67.50

Equation:
A = P(1 + rt)

Calculation:
First, converting R percent to r a decimal
r = R/100 = 2.5%/100 = 0.025 per year.

Solving our equation:
A = 300(1 + (0.025 × 9)) = 367.5
A = $367.50

The total amount accrued, principal plus interest, from simple interest on a principal of $300.00 at a rate of 2.5% per year for 9 years is $367.50.

1. Is the game fair? We are flipping a coin twice. The first player wins if we get 2 tails, and the second player wins if we get 1 head and 1 tail. 2. Is the game fair? we are tossing two dice and the first player wins if the sum on the dice is 9 and the second player wins if the sum on the dice is 5.

Answers

Answer: 1) The game is not fair, 2) The game is fair

Step-by-step explanation:
1) In the case of the coin, we will assume that it is a fair coin and there is an equal probability that the coin will land either heads or tails on each flip. In other words, we are assuming that flipping the coin is a completely random process.

When flipping a coin twice, there are 4 distinct possibilities, where H means the coin lands head side up and T means it lands tails side up. The first letter represents the first flip of the coin and the second represents the second flip. The possible outcomes are:

HH, HT, TH, TT

As you can see, there is only 1 possible outcome where the coin will land tails up twice, while there are 2 possible outcomes where the coin will land heads up once and tails up once. Since the game doesn't specify the order in which the coin needs to land on either side for player 2 to win, both of these possibilities are fair game.

Now, according to our earlier assumption that the process of flipping the coin is truly random, we can say that there is a 50/50, chance of the coin landing on either side before we flip it. There is also a 100% chance that, in 2 flips, the coin behaves according to one of the possibilities stated above. This means that each possibility has an equal 25% chance of happening. We determined there are 2 possible outcomes where the coin lands on both a head and a tail, opposed to the 1 possible outcome where the coin lands tails up on both flips. Adding the probabilities, this means that the second player has a 50% chance of winning the game while the first player only has a 25% chance of winning the game, and thus - it is not fair.

2) In the second game, we will also assume that the process of rolling the dice is completely random and there is an equal chance that it lands on each side. The possible outcomes for both dice combining to sum to 5 are:

1,4; 4,1; 2,3 and 3;2

and the possible outcomes for both dice combining to sum to 9 are:

4,5; 5,4; 2,6 and 6,2

Assuming the dice are normal, 6-sided dice, there is a 1/6 or a 16.67% chance of the dice landing on each side. The outcomes on these rolls are dependent on one another and represent compound probabilities. in other words, the probability of rolling a 2 on a single dice is 16.67%, and the probability of rolling a 6 on a single dice is also 16.67%, but the probability of rolling a 2 on one dice and (key word here being and) a 6 on the other dice is the product of the two individual probabilities;

1/6 * 1/6 = 1/36 (2.78%)

This means that it is less likely to roll the correct combination than it is to roll each of the numbers individually, which should intuitively make sense.

However, because there are an equal number of outcomes in which each player wins, this game is fair to both players. It is no more likely that the sum of the dice will be 9 than it is that it will be 9, even though both of these outcomes have relatively low probabilities. In most rolls, neither player will win - but the game is still fair to both players.

How to find Piecewise function?

Determine which of the following intervals (or inequalities) the input belongs to before evaluating a piecewise function at any given input. The function specification for that specific interval can then simply be updated to reflect the new input.

[tex]f(x)=\left \{ {{3x, if x\leq -1} \atop {-2x+3, if 0 < x < 4}}\atop {2, if x\geq 4}\right.[/tex]

lets take 3x as Interval A

-2x+3 as interval B

and 2 as interval C

Now lets calculate the interval A

f(x)=3x

as x≤-1

∴f(-1) = 3(-1)

=(-3)

∴ point is (-1,-3)

∴f(-2) = 3(-2)

=(-6)

∴ point is (-2,-6)

Now lets calculate the interval B

f(x)=-2x+3

as 0<x<4

∴f(1) = -2(1)+3

=-2+3

∴ point is (1,1)

∴f(2) = -2(2)+3

=-4+3

Without calculating, order the quotients smallest to largest.

Answers

The order of the quotient from smallest to largest is given as follows:

42.6/70, 426/70, 42.6/0.07, 42.6/0.07.

What is a quotient?

A quotient is given by the division of two terms a and b, that is:

a / b.

From this, we have that the dividend a and divisor b are inverse proportional, that is:

A large quotient is achieved when a is large and b is small.A small quotient is achieved when a is small and b is large.

There are three divisions with the same term a, hence they are ordered, from smallest to largest, as follows:

42.6/70, 42.6/0.07, 42.6/0.07.

(the smallest the value of b, the largest the quotient).

The final quotient is:

426/70.

Dividing by 10 to have an equivalent value of a, we have that:

426/70 = 42.6/7.

Which is the second largest value of b, hence the second smallest quotient.

The chance of the spinner landing on blue = 1/4

The chance of the number cube landing on 2 = 1/6

1/4 * 1/6 = the probability of the spinner landing on blue and the cube landing on 2 (Remember that the probability of both happening is smaller, so it cannot be addition.)

Ans = 5/12

The chance of the spinner landing on something that isn’t blue = 3/4

The chance of the number cube landing on 5 = 1/6

3/4 * 1/6 = the total probability

Ans = 1/8

The chance of the spinner landing on red = 1/4

The chance of the number cube landing on an even number = 3/6, 1/2.

1/4 * 1/2 = the total probability

Ans = 1/8

The chance of the spinner landing on yellow = 1/4

The chance of the number cube landing on something that’s not 4 = 5/6

1/4 * 5/6 = the total probability

Ans = 5/24

Answer:-2/5

Answer:

-3/8

Step-by-step explanation:

1) Work out the options you are given

-2/5 = -0.4-3/8 = -0.375

2) Find which one is greater

As the numbers are decimal the 'seemingly greater number' might actually be the smaller one.

To find out which decimal is greater you can easily plot them into a number line.

The number that is further to the left is smaller and the number closer to the right is higher!

If we were to plot the numbers one a number line the -0.375 would be closer to the right meaning it is greater.

HINTS:

To make it easier to divide minus numbers, at first completely forget about the minus (you can plug it back in at the end).

For example, if you were given -2/5 get rid of the minus to get 2/5 and from this we can easily figure out 2 ÷ 5 which would give us 0.4.

At the point where you have your final number you can add the - back in making it -0.4
