Ramona is asked to draw a tree using a scale of 1 inch:3 meters.She draws a 4-inch tree.How tall is the tree?

Kade has 1/6 cup of salad dressing left after using some on a salad. We found this by converting 2/3 cup to 4/6 cup and then subtracting it from the 5/6 cup he initially had.

To find out how much salad dressing Kade has left after using some on a salad, we need to subtract the amount used from the total amount he made. Kade made 5/6 cup of salad dressing and used 2/3 cup on a salad. To perform the subtraction, both fractions need a common denominator. The smallest common denominator for 6 and 3 is 6. The fraction 2/3 can be converted to 4/6 so that both fractions have the same denominator. Now we can subtract:

Hence, Kade has 1/6 cup of salad dressing left after using it on the salad.

Listen, we all feel like we could use a bit of memory training. Let’s start with a small thought experiment. Take a minute to think back to your science classes in high school and see how much you can recall.

Can you explain the elements that make up an atom, or the basic principles of plant biology? How about physics, or simple chemistry? Do facts and procedures come rushing back, or do you remember your teacher’s face, or the way the room smelled after an experiment?

Everyone will have different memories, and they may have very little to do with what you were taught in class. You might not remember anything at all. It’s extraordinary how quickly we manage to forget what we crammed during all those long hours of study. Algebra. Long division. Verbs, adverbs and relative clauses. The causes of World War I. Where did it all go, we muse, years later?

It is extraordinary that so many of the world’s education systems, which are usually based on testing how well a student can recall and apply information, are designed without any real thought of how our memories work. Memory is perhaps the most fundamental factor in how human beings learn. Memory training should inform all aspects of education; instead, it’s an afterthought.

Advances in cognitive science have huge implications for how we learn and remember things. It’s time for policymakers, educators, and anyone who wants to learn something — in other words, all of us — to start listening.

Solution:

we are given that

For every pound a company spends on advertising it spends £0.64 on its websites.

we have been asked to express the amount spent on advertising to the amount on its website it's website as a ratio it's in its simplest form.

We can find the required ratio as below

[tex]Ratio=\frac{1}{0.64} \\ \\ Ratio=\frac{100}{64} \\ \\ Ratio=\frac{25}{16} \\[/tex]

Hence the required ratio is 25:16.

Answer:

Perimeter of given triangle is ( 9.8x + 1.1y + 9.9z ) centimeters.

Step-by-step explanation:

Given : A triangle has a side lengths of (5.5x + 6.2y) centimeters, (4.3x+8.3z) centimeters and (1.6z -5.1y) centimeters  

We have to find the expression  that represents the perimeter (in centimeters)

of the triangle.

Perimeter of a figure is defined as the sum of all the sides.

Since given figure is triangle so perimeter of triangle is the sum of all the sides.

Given side lengths are

(5.5x + 6.2y) , (4.3x + 8.3z) and (1.6z -5.1y)

Thus, perimeter = (5.5x + 6.2y)  + (4.3x + 8.3z) + (1.6z - 5.1y)

Perimeter = 5.5x + 6.2y + 4.3x + 8.3z + 1.6z - 5.1y

LIKE TERMS are term with same variables.

Rearrange, we get

Perimeter = 5.5x + 4.3x + 6.2y - 5.1y + 8.3z + 1.6z

Adding like terms, we get,

Perimeter = (5.5 + 4.3)x + (6.2 - 5.1)y + (8.3 + 1.6)z

Perimeter = (9.8)x + (1.1)y + (9.9)z

Thus, Perimeter of given triangle is 9.8x + 1.1y + 9.9z centimeters.

To simplify the expression (3x^4y^-5)^3, apply the power rule to each term, calculate the result, and combine them. The simplified form is 27x^12y^-15.

How to Simplify the Expression (3x^4y^-5)^3:

Let's simplify the given expression step by step:

(a^m * b^n)^p = a^(m*p) * b^(n*p)

So, (3x^4y^-5)^3 becomes:

(3^3) * (x^(4*3)) * (y^(-5*3))

Putting it all together, we get:

27x^12y^-15

In conclusion, the simplified form of (3x^4y^-5)^3 is 27x^12.y^-15.

To solve this problem, we can use a system of equations to find the number of people who paid $14 for reserved seats and the number of people who paid $5 for general admission.

To solve this problem, we can use a system of equations. Let's say the number of people who paid $14 for reserved seats is 'x', and the number of people who paid $5 for general admission is 'y'.

We know that the total number of people who attended the ballgame is 31,000, so we can write the equation:

x + y = 31,000

We also know that the total receipts from the day were $200,000, so we can write another equation:

14x + 5y = 200,000

Now we can solve this system of equations to find the values of 'x' and 'y'.

Multiplying the first equation by 5, we can eliminate 'y' by subtracting the second equation from it:

5x + 5y = 155,000

-(14x + 5y = 200,000)

Simplifying, we get:

-9x = -45,000

Dividing both sides of the equation by -9, we find that 'x' = 5,000.

Substituting this value back into the first equation, we can solve for 'y':

5,000 + y = 31,000

Simplifying, we get 'y' = 26,000.

Therefore, 5,000 people paid $14 for reserved seats and 26,000 people paid $5 for general admission.

The best estimate of the total cast, in dollars, of the laundry items is $885.

A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.

Given that, the owner purchases 6 cases of laundry soap, 8 cases of fabric softener, and 3 cases of bleach for the laundromat.

Each case of laundry soap costs $68.45

So, the cost of 6 cases of laundry soap

= 6×68.45

= $410.7

Each case of fabric softener costs $39.71

So, the cost of 8 cases of fabric softener

= 8×39.71

= $317.68

Each case of bleach costs $52.25

So, the cost of 3 cases of bleach for the laundromat

= 3×52.25

= $156.75

Total =410.7+317.68+156.75

= $885.13

≈ $885

Therefore, the best estimate of the total cast, in dollars, of the laundry items is $885.

Percent” means “out of 100” so the decimal point moves when you rewrite a percent as a decimal and when you rewrite a decimal as a percent.

percentage, a relative value indicating hundredth parts of any quantity.

It’s not that we “move” the decimal point. It’s just that in converting a numeral to percent notation results in the decimal point being in a different place by 2 places.

What we are really doing when we convert a numeral to decimal notation can be thought of as multiplying by 1 — which doesn’t change a numbers value — but multiplying by 1 written in a special way.

You see, “percent” means “out of 100”. So the number 1 is how many parts out of 100? If you break a single thing into 100 pieces, you have 100 pieces.

1 = 100%

Hence, percent” means “out of 100” so the decimal point moves when you rewrite a percent as a decimal and when you rewrite a decimal as a percent.

B, {2.5, 3, 3.5}

Step-by-step explanation:

Some people said it was D but I put that and got 0 points for that question.

Anyways it's B, Choose me for brainliest pleaseeeee.

The set of numbers satisfying the inequality is {2.5, 3, 3.5}. The correct option is B.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Given that sets show all the numbers from the set {0.5, 1, 2.5, 3, 3.5} that make the inequality 4a + 2 ≥ 12 true.

The set of numbers is {2.5, 3, 3.5}.

4a + 2 ≥ 12

4 x 2.5 + 2 ≥ 12

`12 ≥ 12 True

4a + 2 ≥ 12

4 x3  + 2 ≥ 12

14 ≥ 12 True

4a + 2 ≥ 12

4 x 3.5 + 2 ≥ 12

The parabola will become narrower, the correct option is B.

For a function f(x), we define a vertical stretch of scale factor k as:

g(x) = k*f(x).

If k > 1, we have a stretch, if 0 < k < 1, we have a contraction.

In this case, we have:

So we have a vertical stretch of scale factor 2, this means that we are stretching our function vertically, so it will become narrower, meaning that the correct option is B.
