To carry Triangle A onto Triangle A', one can use a sequence of geometric transformations such as translation, rotation, and reflection. An example sequence could include translating the triangle, rotating it, and then reflecting it across an axis.

To answer the question on how to carry Triangle A onto Triangle A', we need to consider a sequence of geometric transformations. Without the specific diagram, we can only provide a general solution. Typically, transformations to carry one triangle onto another include translations, rotations, reflections, or a combination of these. For example, we may translate Triangle A horizontally or vertically, followed by a rotation around a point at a certain angle, and possibly apply a reflection across a line if the orientation of Triangle A' is opposite that of Triangle A. Example of a Sequence of Transformations:  This sequence would successfully carry Triangle A onto Triangle A' given the right conditions.

Final answer:

By establishing an equation G = k(B/T), where G is the number of girls, B is the number of boys, and T is the number of teachers, we determine the constant of proportionality (k) from the given values. Using this constant, we deduce that there are 10 boys when there are 10 girls and 100 teachers.

Explanation:

The number of girls varies directly as the number of boys (B) and inversely as the number of teachers (T). This can be written as an equation, G = k(B/T), where G is the number of girls, and k is a constant of proportionality. From the given information, when there were 50 girls, there were 20 teachers and 10 boys. Plugging these values into the equation gives us 50 = k(10/20), which simplifies to 50 = k/2. Solving for k gives us k = 100.

Now, to find out how many boys are there when there are 10 girls and 100 teachers, we use the equation with our value for k. We get 10 = 100(B/100). Simplifying this equation gives us 10 = B. Therefore, there are 10 boys when there are 10 girls and 100 teachers.

Step-by-step explanation:

We have proven that:

[tex]\[\frac{a + bz}{a + b} = \frac{c + dz}{d + c}\][/tex]

given that bc = ad.

To prove that

[tex]\[\frac{a + bz}{a + b} = \frac{c + dz}{d + c}\][/tex]

given that bc = ad, we'll start by manipulating one side of the equation to look like the other side.

Let's start with the left-hand side:

[tex]\[\frac{a + bz}{a + b}\][/tex]

To make it look like the right-hand side, we need to somehow introduce c and d into the expression.

From the given condition bc = ad, we can rearrange it to solve for d:

[tex]\[d = \frac{bc}{a}\]Now, let's substitute \( d \) into the expression:\[\frac{a + bz}{a + b} = \frac{c + \frac{bc}{a}z}{\frac{bc}{a} + c}\][/tex]

Now, to make it look like [tex]\( \frac{c + dz}{d + c} \), we need to factor \( c \)[/tex] out of the numerator:

[tex]\[= \frac{c\left(1 + \frac{bz}{a}\right)}{c\left(\frac{b}{a} + 1\right)}\]Notice that \( c \) cancels out in the fraction:\[= \frac{1 + \frac{bz}{a}}{\frac{b}{a} + 1}\]Now, we notice that \( \frac{b}{a} = \frac{c}{d} \), because \( bc = ad \). So, we can rewrite this as:\[= \frac{1 + \frac{bz}{a}}{\frac{c}{d} + 1}\][/tex]

This is now the same form as [tex]\( \frac{c + dz}{d + c} \), where \( d = \frac{bc}{a} \).[/tex]

So, we have proven that:

[tex]\[\frac{a + bz}{a + b} = \frac{c + dz}{d + c}\][/tex]

given that bc = ad.

Complete question:

Prove that (a+bz)/(a+b)=(c+dz)/(d+c) if bc=ad

We have proven that:

[tex]\[(a + bz)/(a + b) = (c + dz)/(d + c)\][/tex]

given that bc = ad.

To prove that

[tex]\[(a + bz)/(a + b) = (c + dz)/(d + c)\][/tex]

given that bc = ad, we'll start by manipulating one side of the equation to look like the other side.

Let's start with the left-hand side:

[tex]\[(a + bz)/(a + b)\][/tex]

To make it look like the right-hand side, we need to somehow introduce c and d into the expression.

From the given condition bc = ad, we can rearrange it to solve for d:

[tex]\[d = (bc)/(a)\]Now, let's substitute \( d \) into the expression:\[(a + bz)/(a + b) = (c + (bc)/(a)z)/((bc)/(a) + c)\][/tex]

Now, to make it look like [tex]\( (c + dz)/(d + c) \)[/tex], we need to factor \( c \) out of the numerator:

[tex]\[= (c\left(1 + (bz)/(a)\right))/(c\left((b)/(a) + 1\right))\]\\Notice that \( c \) cancels out in the fraction:\[= (1 + (bz)/(a))/((b)/(a) + 1)\][/tex]

Now, we notice that [tex]\( (b)/(a) = (c)/(d) \)[/tex], because [tex]\( bc = ad \)[/tex]. So, we can rewrite this as:[tex]\[= (1 + (bz)/(a))/((c)/(d) + 1)\][/tex]

This is now the same form as [tex]\( (c + dz)/(d + c) \), where \( d = (bc)/(a) \)[/tex].

So, we have proven that:

[tex]\[(a + bz)/(a + b) = (c + dz)/(d + c)\][/tex]

given that bc = ad.

Prove that (a+bz)/(a+b)=(c+dz)/(d+c) if bc=ad.

The power of the girl is 24.5 Watts.

Given data:

The mass M = 25 kg, where the height of each step is 0.25m and the number of steps is 8.

To calculate the power of the girl:

Power = Work / Time

The work done is equal to the force applied multiplied by the distance covered.

Work = Force * Distance

The force applied is equal to the weight of the girl, which is given by:

Force = Mass * Gravity

Where gravity is approximately 9.8 m/s².

Force = 25 kg * 9.8 m/s² = 245 N

The distance covered is equal to the height of each step multiplied by the number of steps climbed.

Distance = Height * Number of Steps

Distance = 0.25 m/step * 8 steps = 2 m

Now, calculate the work:

Work = 245 N * 2 m = 490 J

Next, calculate the power by dividing the work by the time:

Power = 490 J / 20 s = 24.5 W

Hence, the power is 24.5 Watts.

Answer:

Step-by-step explanation:

If the jacket was discounted at 25%, that means that you get 25% off, right?  What it also means is that you are still paying 75%.  To get to the price of the jacket on sale, multiply the price of the jacket by 75% (as a decimal):

290(.75) = 217.50

That's the price of the jacket when it is 25% off the original price.  If Arianna got an additional 10% off that price, that means she got 10% off but is still paying 90%.  To get to the final price that she paid, multiply the sale price of the jacket by 90% (as a decimal):

217.50(.90) = 195.75

That's what she paid in the end for the jacket (i guess not counting tax...?)

To find the price Arianna paid for the ski jacket, multiply the original price by the discount and coupon percentages.

To find the price Arianna paid for the ski jacket, we need to calculate the discounts. First, we find the sale price by multiplying the original price by the discount percentage: $290 * 0.75 (100% - 25%) = $217.50. Then, we apply the coupon discount by multiplying the sale price by the coupon percentage: $217.50 * 0.90 (100% - 10%) = $195.75. Therefore, Arianna paid $195.75 for the ski jacket.

Two 1 kg blocks sliding down frictionless inclined planes will take the same amount of time.

The correct statement is that both blocks will take the same amount of time to slide down the inclined planes.

When the blocks slide down the inclined planes, their acceleration is determined by the force of gravity acting on them. Since the mass of both blocks is the same and the force of gravity is the same for both, their acceleration will be the same.

Additionally, the height of the inclined planes is the same for both blocks, so they will cover the same vertical distance. As a result, the time taken for both blocks to slide down will be the same.

Answer:

s=p*.2

Step-by-step explanation:

.2 is 20 percent in decimal form

Final answer:

The equation that relates the sale price (s) to the original price (p) during a 20% off sale is s = 0.80p, showcasing the discounted price is 80% of the original price.

Explanation:

When a book is on sale for 20% off, the sale price, s, can be calculated from the original price, p, using the equation:

s = p - (0.20 × p)

This equation relies on the concept that a 20% discount reduces the original price by a factor of 20%. To express this as a mathematical operation, we multiply the original price by 20% (or 0.20) and subtract that value from the original price to obtain the sale price.

You can also simplify the equation:

s = p - 0.20p

s = (1 - 0.20)p

s = 0.80p

So the equation that relates the sale price to the original price is:

s = 0.80p

We can see that the y-value does not change on the interval C, so the correct option is "linear constant".

A linear equation is of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

A horizontal line, also called a constant line, is of the form:

y = b

Where the slope is 0.
