The sum of a number times 2 and 29 is at least −25

Number of seconds in a year riddle will be 31,536,000 seconds in a year ((24 x 60 x 60) x 365).

To calculate number of seconds in year riddle, we need to calculate the no. of seconds in each month.

There are a total 12 months and each month consists of 31, 30 and 28 days respectively.

Now, calculating the number of seconds in each month multiplying the count of months with respect to the number of days in that month.

In January, March, May, July, August, October, December : 31x24x60x60=26,78,400x7=1,87,48,800

In Feb: 28X24x60x60=24,19,200

In April, June, September, November: 30x24x60x60=25,92,000x4=1,03,68,000

Now add all the values: No of Seconds in year riddle = 1,87,48,800+24,19,200+1,03,68,000

Totally the value will be equal to 3,15,36,000 seconds.

Answer: y = 6x

Step-by-step explanation:

Answer:

y = 6x

In real-world terms
x = number of sandwiches

y = total cost of x sandwiches in dollar amounts

Step-by-step explanation:

The first piece of advice I have for you is to have confidence in yourself that you will succeed. That is what learners and tutors here at brainly are for. To help out.

Now to explanation of the problem and solution
The linear equation of a graph can be written in a couple of ways. On ios the standard form which is of the form
Ax + By = C where A, B and C are constants

The other is in slope-intercept form which is written as
y = mx + b

Here m is the slope which is also referred to as rise/run. I will explain these terms as we solve the problem

b is the y-intercept. This is the y-value at which the line crosses the y-axis. It corresponds to the value of y when x = 0

Sometimes the graph will not show the complete line so we cannot determine where the line crosses the y-axis. In this case this determination is a cinch

Looking at the graph, we see the line crosses the y-axis at (0,0) which is the origin

Therefore the y-intercept is 0 and hence b=0

Hence we get the line equation as

y = mx + b
==> y = mx + 0
==> y = mx

Let's find m, the slope:
Take any two points on the line. Here two points have been identified as (1, 6) and (4, 24)

The difference in y-values for these two points is 24 - 6 = 18.
This difference in y-values is known as the rise since it is measured vertically

The corresponding difference in x values is 4  - 1 = 3
This is referred to as run because it is measured horizontally

The slope m = rise/run
Here m = 18/3 = 6

Therefore plugging in m = 6 the equation in slope-intercept form is
y = 6x

Slope has another meaning. It signifies the rate of change
In this particular case in real-world terms it means that the cost of sandwiches is proportional to the number of sandwiches

Every sandwich you purchase will cost you $6 more

So the cost per sandwich is $6

For 1 sandwich -→ $6,

For 2 sandwiches → $12

For 7 sandwiches → $42

and all this is clearly evident in the graph

Hope that helps you and good luck on all your subjects

Answer:

If you are asking if y = 4x is proportional, the answer is yes.  It is linear and it goes through the origin.

Step-by-step explanation:

Note that the cost of wax that is required to cover the floor is given as = $1.677.39

To arrive at the correct answer, we had to deconstruct the complex shape in regular shapes comprising two rectangles and one right-angled triangle.

When disassembled, a composite form (or complex figure), also known as a compound shape, is made up of several separate regular shapes.

Note that the arrive at the correct answer, we need to deconstruct the complex shape in regular shapes comprising two rectangles and one right-angled triangle.

The objective is to add the area of all the shapes which comprise the irregular floor and multiply by the cost of wax per square foot. (See attached Image for Deconstructed Compound Shape.)

Step 1 - Find the area of the Right-Angled Triangle

Recall that the rea of a Right Angled Triangle = 1/2 B*H;

B = 15ft

H = 35ft

Area of Δ = 1/2 * 15 *35

Area of Triangle = 262.5ft

Step 2 - Find the area of the Two Rectangles
Dimensions of Rectangle a are: L = 30ft; B = 15ft

Area = L*B

Area = 30*15

Area of (a) = 450ft

Dimensions of Rectangle b are: L = 25ft: B= 20ft
Area (b) = 25* 20

Area (b) = 500ft


Step 3 - Find the area of the compound shape
Area of the compound shape = Sum of the area of the individual shapes  =

262.5ft + 450ft + 500ft
= 1212.5 ft

Step 4 - Find the cost of waxing the floor (compound shape)
This is given as:

$1.38 * Area of Compound Shape

⇒ 1.38 * 1212.5
= $1.677.39

Answer: 1/2(10+x)

Step-by-step explanation:

"Half the sum of 10 and a number" means 1/2(10+x), where x is the unknown number.

The probability of rolling a 9 or higher on the 3rd roll is 4/27, or approximately 14.8%.

Probability is a branch of mathematics that deals with determining the likelihood or chance of an event occurring. It is often expressed as a fraction or a percentage.

Conditional probability is the probability of an event happening given that another event has already happened.

The probability of not rolling a 9 or higher on the first roll is 8/12 or 2/3, as there are 8 numbers on the cube that are less than 9.

The same is true for the second roll, so the probability of not rolling a 9 or higher on the first two rolls is (2/3) * (2/3) = 4/9.

The probability of rolling a 9 or higher on the third roll is 4/12 or 1/3, as there are 4 numbers on the cube that are 9 or higher.

So, the probability of rolling a 9 or higher on the third roll given that the previous two rolls did not result in a 9 or higher is

=> (4/9) * (1/3) = 4/27

To find the volume of a triangular prism, you will need to use the formula V = (1/2)bhL, where V is the volume, b is the base of the triangular prism, h is the height of the triangular prism, and L is the length of the triangular prism.

Here is a step-by-step explanation on how to find the volume of a triangular prism:

Step 1: Find the base of the triangular prism. This will be one of the sides of the triangular base.

Step 2: Find the height of the triangular prism. This will be the distance from the base to the opposite vertex.

Step 3: Find the length of the triangular prism. This will be the distance between the two triangular bases.

Step 4: Plug in the values for the base, height, and length into the formula V = (1/2)bhL.

Step 5: Simplify the equation to find the volume of the triangular prism.

For example, if the base of the triangular prism is 4, the height is 3, and the length is 6, the volume would be:

V = (1/2)bhL

V = (1/2)(4)(3)(6)

V = 36

Hi, to answer this question we have to write an equation with the information given:

Tip amount: $2.0

Percentage: 25% = 0.25 (decimal form, 25/100=0.25)

So, if we multiply the taco's price (x) by the percentage (0.25) we will obtain the amount of the tip (2).

Mathematically speaking:

x (0.25) = 2

Solving for x

x = 2/0.25

x = 8

The price of Andrea's tacos is $8.

The required proportional relationship used to evaluate the measure of segment LM is 9/LM = 6/4.5. Option D is correct.

Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.

Here,
Since Triangle HJK is similar to triangle LMN.
The property of similar triangle states that the sides of both the triangle will be proportional to each other.
So,

With the sequence having sum of four consecutive integers as 198 , the fourth integer in the sequence is calculated to be 51.

Let's call the first integer in the sequence "x". Since the integers are consecutive, the next three integers in the sequence would be "x + 1", "x + 2", and "x + 3". The sum of these four integers can be represented as:

x + (x + 1) + (x + 2) + (x + 3) = 198

Expanding and simplifying the left side of the equation, we get:

4x + 6 = 198

Subtracting 6 from both sides of the equation, we get:

4x = 192

Dividing both sides of the equation by 4, we get:

Answer: The empirical rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

In this case, the mean of Xochitl's finishing times is 84 seconds and the standard deviation is 2.5 seconds, so the interval that represents the middle 68% of her finishing times is:

[84 - 2.5, 84 + 2.5] = [81.5, 86.5]

The value of x is 8 units by using Pythagorean theorem.

If x and 6 are the lengths of the legs of a right triangle and the length of the hypotenuse is 10, then we can use the Pythagorean theorem to find the value of x.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.

So in this case:

x^2 + 6^2 = 10^2

Expanding the squares and solving for x:

x² + 36 = 100

x² = 100 - 36

x² = 64

x = [tex]\sqrt{64}[/tex]
