Answer:

1:2:3

Step-by-step explanation:

The ratio 20:40:60 is simplified by dividing each number by the greatest common divisor (GCD), which is 20, giving us the simplest form of the ratio as 1:2:3.

To write a ratio in simplest form, you have to find the greatest common divisor (GCD) of the numbers and then divide all numbers by the GCD. In the ratio 20:40:60, the GCD is 20. Therefore, when you divide each number of the ratio by the GCD you get 1:2:3. So, the ratio 20:40:60 in its simplest form is 1:2:3.

The solution to the equation 3y + 6 + 4y - 7 = -8 is y = -1.

We have,

To solve the equation 3y + 6 + 4y - 7 = -8 for y, we can combine like terms and isolate the variable.

Combining like terms on the left side of the equation, we have:

3y + 4y + 6 - 7 = -8

Simplifying further:

7y - 1 = -8

Next, let's isolate the y-term by moving the constant term to the other side of the equation:

7y = -8 + 1

Simplifying:

7y = -7

Finally, divide both sides of the equation by 7 to solve for y:

y = -7/7

Simplifying the fraction:

y = -1

Therefore,

The solution to the equation 3y + 6 + 4y - 7 = -8 is y = -1.

Given:

Given that the height of the pyramid is 12 units.

The base of the triangle is 8 units.

The height of the triangle is 6 units.

We need to determine the volume of the pyramid.

Area of the triangle:

The area of the triangle can be determined using the formula,

[tex]A=\frac{1}{2} bh[/tex]

where b is the base of the triangle and h is the height of the triangle.

Substituting the values, we get;

[tex]A=\frac{1}{2}(8)(6)[/tex]

[tex]A=\frac{1}{2}(48)[/tex]

[tex]A=24[/tex]

Thus, the area of the triangle is 24 square units.

Volume of the pyramid:

The volume of the pyramid can be determined using the formula,

[tex]V=\frac{1}{3}AH[/tex]

where A is the area of the triangle and H is the height of the pyramid.

Substituting the values, we get;

[tex]V=\frac{1}{3}(24)(12)[/tex]

[tex]V=\frac{1}{3}(288)[/tex]

[tex]V=96[/tex]

Thus, the volume of the pyramid is 96 cubic units.

Step-by-step explanation:

Given a parallelogram with points

X(4, 0)

W(0, -1)

Y(3, -2)

Z(-1, -3)

We want to find the perimeter, perimeter is the total sum of the lengths

So, we need to find the length of the sides using distance between two points

D = √(x2-x1)² + (y2-y1)²

So, applying this

WX = √(0-4)²+(-1-0)² = √(16 + 1) = √17

XY = √(4-3)² + (0--2)² = √(1+4) = √5

Since the opposite sides of a parallelogram are equal, we don't need to find the other length

Then,

Perimeter = 2(WX + XY)

Perimeter = 2(√17 + √5)

Perimeter = 2√17 + 2√5

The correct answer is B.

In a right triangle with one leg of length 3, the other leg of length 4, and the hypotenuse of length x, the Pythagorean theorem formula (3² + 4² = x²) gives the length of x as √25, or 5 units.

In Mathematics, a right triangle has one angle that is a right angle (90 degrees). In these triangles, the Pythagorean theorem applies, which says that the square of the length of the longest side (hypotenuse) is equal to the sum of squares of the other two sides (legs).

If x is a leg of the triangle, then its length can be found by rearranging the Pythagorean theorem formula. If the length of one leg is 3, the other is 4, and the length of the hypotenuse is x, then the equation is: 3² + 4² = x².

That simplifies to 9 + 16 = x², and further to x² = 25. Taking the square root of both sides gives us the length of x as 5 units.

Let w represent width of the pathway.

We have been given that a rectangular garden measuring 13 meters by 15 meters is to have a gravel pathway of constant width built all around it.

Since pathway will be on all sides, so new length and width of garden with pathway would be [tex]13+2w[/tex] by [tex]15+2w[/tex].

We are also told that there is enough gravel to cover 80 square meters. This means that area f pathway should be equal to 80 square meters.

The area of the pathway will be equal to area of garden with new dimensions minus area of garden with original dimensions.

We know that area of rectangle is width times length.

[tex]\text{Area of pathway}=(15+2w)(13+2w)-15(13)[/tex]

Since we are asked to write an inequality that represents all possible widths(w), in meters, of the pathway, so area of pathway should be less than or equal to 80 square meters.

[tex](15+2w)(13+2w)-15(13)\leq 80[/tex]

Therefore, our required inequality would be [tex](15+2w)(13+2w)-15(13)\leq 80[/tex].

Answer:

Step-by-step explanation:

We would apply the formula,

y = ab^t

Where

a represents the initial amount of substance.

t represents the decay time.

From the information given

a = 100

t = 12 hours

Since after 12 hours, the amount of substance reduces by 0.1, then

y = 0.1 × 100 = 10

Therefore

10 = 100 × b^12

Dividing through by 100, it becomes

0.1 = b^12

Raising both sides of the equation by 1/12, it becomes

0.1^(1/12) = b^12/12

b = 0.8

The equation becomes

y = 100(0.8)^t

Where t = n, the expression becomes

y = 100(0.8)^n

Final answer:

The correct expression representing the amount of a radioactive substance left after n days, with a 10% decrease every 12 hours, is 100(0.81)^n. The decay process is exponential, and we square the 12-hour decay factor to get the daily decay factor of 0.81.

Explanation:

To determine which expression represents the grams of a radioactive substance left n days from now, given that the substance decreases by 10% every 12 hours, we'll have to work with the concept of exponential decay in our calculations. Since the decay happens every 12 hours (which is half a day), we'll count the number of half-days there are in n days, which is 2n 12-hour periods.

Since the substance decreases by 10%, it retains 90% of its previous amount every 12 hours. In decimal form, this is a 0.9 multiplier. Thus, after each 12-hour period, we multiply the current amount by 0.9. To get the amount after n days, we raise 0.9 to the power of 2n, because there are 2n 12-hour periods in n days.

In mathematical terms, the amount left after n days can be represented as 100(0.9)^(2n). However, this option is not present in the given choices, so we have to look for an equivalent expression by simplifying or altering the base if needed. We can square 0.9 to get 0.81, which corresponds to the amount of substance left after a full day (24 hours). The correct expression representing the amount after n days is 100(0.81)^n, which is choice A.

Answer:

Step-by-step explanation:

The name of the chart is "Participants PER race"

That means they tall you how many people did the race now all you gotta do is, Count up the numbers more than 61- So look at the 6 in the "stem" portion

it has 67, 67 they are both more than 61

Then look at the next "stem" number- 7

that has 74 which is more than 61 but less than 85

Then we look at the 8 in the "stem" it has three numbers- 84, 86, 89

but 86 and 89 are more than 85 so 84 is the only one which will go through

So the numbers are: 67, 67, 74, and 84

Thus 4 participants
