Answer:

height: 16 inch

length of base: 10 inch

width of base: 50 feet

Step-by-step explanation:

128*(1/8)=16 inch

80*(1/8)=10 inch

x*1/8=6.25

x=6.25*8=50 feet

The height and length of the model will be 16 in and 10 in respectively, and  the width of the building will be 50 feet.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

Given that, the scale factor of the building and a model of it is 1/8.

Height of the model = 128/8 = 16 in

Length of the model = 80/8 = 10 in

Width of the model = 6.25*8 = 50

Hence, The height and length of the model will be 16 in and 10 in respectively, and  the width of the building will be 50 feet.

Step-by-step explanation:

The value of 524 divided by 24 is 22.

Divide the leftmost digit of the dividend (528) by the divisor (24).

Since 5 is less than 24, we consider the next digit as well, resulting in 52.

Now, divide 52 by 24. The quotient is 2, and the remainder is 4. Write down the quotient above the line.

Multiply the quotient (2) by the divisor (24), which gives us 48.

Subtract the product (48) from the previous step from the 52. The result is 4.

Bring down the next digit of the dividend (8) next to the remainder (4), resulting in 48.

Divide 48 by 24.

The quotient is 2, and there is no remainder.

Write down the quotient (2) above the line.

Therefore, the result of 528 ÷ 24 using partial products is 22.

Step-by-step explanation:

The effect because of which 15 subjects stated that they had less irritation after having cream with no active ingredient is placebo effect.

The placebo effect occurs when a person's physical or mental health appears to improve after receiving a placebo or "dummy" treatment. injections, or even sham surgery.

The placebo effect is caused by an individual's belief in the benefits of the treatment and the expectation that it will make them feel better, rather than by the properties of the placebo.  

Given,

50 subjects were assigned to the cream with no active ingredient, 15 stated they had less irritation.

The cream with no active ingredient is placebo, and this effect is called placebo effect.

Hence, 15 subjects stated that they had less irritation is a result of placebo effect.

For every 3 lemons Chrissy buys at a farm stand, the total cost increases by $1.80.

cost or 1 lemon = 1.8/3 = $0.6

It means the constant of proportionality is 0.6

If there are x no of lemons, then the total cost will be given by :

y = 0.6x

Hence, this is the required solution.

A- Verify corresponding pairs of ANGLES are congruent by TRANSLATION.

Step-by-step explanation:

You find the congruent pairs by the angles, not the sides. Because the sides can be the same size but the angles can possibly not be congruent so you check by the angles. And Translation because you don't change the size of the object to see if it's congruent.

Similar triangles may or may not have congruent side lengths.

The true statement is: (a) verify corresponding pairs of angles are congruent by translation.

For the two triangles to be similar, the side lengths of both triangles may or may not be equal.

This means that: options (b) and (d) are not true

Translation does not alter side lengths and angles, while dilation alters measure of angles.

This means that:

The pair of corresponding angles should be checked by translating the triangles.

Hence, the true statement is: (a)

Answer:

Step-by-step explanation:

If we consider a triangle with the length of the hypotenuse being equal to 1 and the length of the opposite side = 3x.

However, recall that in a right-angle triangle;

SIne = opposite/hypothenuse

Thus; let the angle facing the opposite be y

Then;

SIn y = 3x/1

Sin y = 3x

Thus, y = arcsin (3x)

Now; to find cos(arcsin 3x)

Recall that:

Cosine = adjacent/hypotenuse

Now, using Pythagoras rule;

[tex]\mathsf{Adjacent \ side = \sqrt{(hypotenuse)^2 -(opposite^2)}}[/tex]

[tex]\mathsf{Adjacent \ side = \sqrt{(1)^2 -(3x^2)}}[/tex]

[tex]\mathsf{Adjacent \ side = \sqrt{1 -9x^2}}[/tex]

cos(arcsin 3x) = cos y = adjacent side/hypotenuse = [tex]\dfrac{\sqrt{1 -9x^2}}{1}[/tex]

cos(arcsin 3x) = [tex]\dfrac{\sqrt{1 -9x^2}}{1}[/tex]
