find the missing dimension. base: 27 cm and area: 256.5 cm sq

Answers

What is the figure? A square a triangle ect?
You are trying to find height. I am assuming this is a rectangle you are computing, so I will use

Base • Height = Area

(27) • Height = 256.5 // Plugging in what we know

As per Algebra, you have to be able to manipulate terms in an equation in order to find an answer. In reality, it’s right there, just not in a visible form. To do that, go ahead and divide both sides of the equation by 27; this gets rid of the 27, leaving Height, what we want, alone.

(27/27) • Height = 256.5/27 // Division Property of equality
Height = 9.5 cm

Factor the expression. d^2-14d+49

Answers

Answer: (d - 7)^2

Procedure to factor:

The expression to factor is a trinomial.

Steps:

1) Probe whether this is a perfect square trinomial, i.e a trinomial that can be factored as (a + b)^2 or (a - b)^2.:

2) Determine if the first and the third terms of the trinomial (once it is ordered, which it is) have exact square roots:

√ (d^2) = d

√49 = 7

3) Since they have exact square roots, test wether the second term of the trinomial equals twice the product of the two square roots determined:

=> 2 * (d) * (7) = 14d which is exactly the second term of the trinomial

4) Now you can write the binomial squared using the sign of the second term. This is:

(d - 7)^2.

You can prove that that is the answer by expanding the binomial squared, which must drive back to the original expression: d^2 - 2(7)(d) + 7^2 = d^2 - 14d + 49.

Given a circle with measures of (C, d, and r) and a circle with measures of (C', d', and r'), what is r if C C' = 5 and d' = 20?

Answers

Answer:

r = 50

Step-by-step explanation:

We know that:

[tex]\frac{C}{C'}=5[/tex][tex]d'=20[/tex]

So, the ratio between the circumferences is 4 and the diameter of the second circle is 20. In this case, we have to use the ratio between those two circumferences, because that's what is our given data.

[tex]\frac{C}{C'}=\frac{d}{d'}\\5=\frac{d}{20}\\ 100=d[/tex]

From this proportion, we deduct that the diameter of the initial circle is 100. Now, we know that the radius in a circumference is have the diameter. Therefore, the radius is:

A study found that 9% of dog owners brush their dogs teeth. Of 578 dog owners, about how many would be expected to brush their dogs teeth? Explain. Please help I am confused

Answers

9 percent of 578 is 52.02.
578/x=100/9
(578/x)*x=(100/9)*x       - we multiply both sides of the equation by x
578=11.111111111111*x       - we divide both sides of the equation by (11.111111111111) to get x
578/11.111111111111=x 
52.02=x 
x=52.02

Final answer:

About 52 dog owners would be expected to brush their dog's teeth.

Explanation:

The question is asking to estimate the number of dog owners who brush their dogs' teeth based on the given percentage from a study. To calculate this, you would take the total number of dog owners and multiply it by the percentage that brush their dogs' teeth. In this case, there are 578 dog owners and 9% of them are expected to brush their dogs' teeth.

Here is the calculation:

Number of dog owners who brush their dogs' teeth = Total number of dog owners × Percentage of owners who brush teethNumber of dog owners who brush their dogs' teeth = 578 × 0.09Number of dog owners who brush their dogs' teeth ≈ 52

Therefore, about 52 dog owners out of 578 are expected to brush their dogs' teeth.

The length of a rectangle is 3 inches more that its width. The perimeter of the rectangle is at least 30 inches. Which inequality shows the possible range of widths of the rectangle?

A. w ≥ 16.5 inches
B. w ≥ 13.5 inches
C. w ≥ 9 inches
D. w ≥ 6 inches

Answers

Perimeter of a rectangle: 2(l + w)

2(l + w) ≥ 30 in


Simplify- divide both sides by 2.

l + w ≥ 15 in


Substitute (w + 3) into l so only 1 variable is used.

(w + 3) + w ≥ 15 in


Simplify further- add variables and subtract 3 from both sides.

2w ≥ 12 in


Divide both sides by 2.

w ≥ 6 in

The perimeter is simple enough, just add all the lengths.
10+5+2+2+2+3+8+7+2+3= 44 inches = Perimeter

Now let's solve the area:
Step 1 let's get the area of the 10-inch square and deduct the missing square and rectangle.
10²=A = 100 in²
Now let's solve the 2-inch square a= 2²= A 4²
Now the rectangle is given l=7 w=2 = A = 14 in²

now subtract 100-4-14= 82 in² is the Area if the Figure

Thus: Area = 82 in² & Perimeter = 44 inches

triangle ABC undergoes a series of transformations to result in Triangle DF is triangle DEF congruent to triangle ABC

Answers

Answer :

Triangle ABC is translated 3 units up and 5 units right , and then rotated 90° clockwise to form traingle DEF.

Since, translation and rotation both are rigid transformations which maps only congruent images. They do not change the size and shape of pre-image.

Thus, here ΔABC is congruent to ΔDEF.

Triangle ABC is reflected over x axis ,and then translated 6 units down to form triangle DEF.

Since, translation and reflection both are rigid transformations which maps only congruent images. They do not change the size and shape of pre-image.

Thus, here ΔABC is congruent to ΔDEF.

Triangle ABC is rotated 180°, and then dilated by a scale factor of 3 to form triangle DEF.

Here rotation is a rigid transformation which maps only congruent images but dilation is not a rigid transformation because it produces similar images for scale factor other than 1 (with scale factor 1 it also produce congruent images) .

Thus, here ΔABC is not congruent to ΔDEF.

Final answer:

The determination of congruency between Triangle DEF and Triangle ABC depends on the nature of the transformations applied to Triangle ABC. If these transformations are rigid motions, then Triangle DEF will be congruent to Triangle ABC.

Explanation:

The question concerns whether Triangle DEF is congruent to Triangle ABC after undergoing a series of transformations. Congruent triangles are those that are identical in terms of size and shape, meaning their corresponding sides and angles are equal.

According to the given information, to determine congruency, we must consider the properties of the transformations involved. If the transformations applied to Triangle ABC are rigid motions (such as rotation, reflection, or translation), which do not alter the shape or size of figures, then Triangle DEF will be congruent to Triangle ABC. If however, the transformations include dilation or other non-rigid transformations that change the size but not the shape, Triangle DEF would not be congruent, although it could be similar to Triangle ABC.

Since the question provided involves linear transformations that transform lines into lines and take parallel lines to parallel lines, it is likely referring to rigid motions. Therefore, it suggests that Triangle DEF should be congruent to Triangle ABC, assuming that the series of transformations includes only those that preserve lengths and angles.

They would advise you to do something with your money that will get you more money in return
Final answer:

Financial consultants argue against keeping cash at home and suggest opening a savings account or investing in a certificate of deposit (CD) for safer and more effective saving methods.

Explanation:

Financial consultants argue against the old-fashioned method of saving money by stuffing it in a mattress or hiding it in a cookie jar because it is not a safe or effective way to save. Keeping cash in your home puts it at risk of theft or loss, and it does not provide any potential for growth or earning interest. Instead, a financial consultant may suggest opening a savings account at a bank or credit union. This allows your money to be securely stored and can also earn interest over time. Another option they may recommend is investing in a certificate of deposit (CD), which offers a higher interest rate but requires depositing the money for a specific period of time.

Answers

The answer is (3,2)

To get this answer we either...
A) Multiply both coordinates by 1/3
or
B) Divide each coordinate by 3

9*(1/3) = 9/3 = 3
6*(1/3) = 6/3 = 2
Final answer:

To dilate the point (9, 6) using a scale factor of 1/3, multiply the x-coordinate and y-coordinate by the scale factor to find the new coordinates which are (3, 2).

Explanation:

To dilate the point (9, 6) using a scale factor of 1/3, we can multiply the x-coordinate and y-coordinate of the point by the scale factor to find the new coordinates.

For the x-coordinate, we have (9) * (1/3) = 3.

For the y-coordinate, we have (6) * (1/3) = 2.

So the dilated point is (3, 2).
