Two rectangles are similar. If the height of the first rectangle is 3 inches, and the height of the second rectangle is 9 inches, how much longer is the second rectangle's perimeter? 3 times as long 6 times as long 9 times as long 6 inches longer

Answers

3 times as long .....hope this helps

Answer:

Option a.

Step-by-step explanation:

Two rectangles are similar. Height of one rectangle is 3 inches and height of second rectangle is 9 inches.

Let width of rectangles are x inches and y inches.

Then width of the second rectangle will be in the same ratio as of their heights.

[tex]\frac{x}{y} =\frac{3}{9}[/tex]

[tex]\frac{x}{y} =\frac{1}{3}[/tex] ⇒ x = [tex]\frac{y}{3}[/tex]

Now perimeter of first rectangle P₁ = 3 + 3 + x + x = 2x + 6

Perimeter of second rectangle P₂ = 9 + 9 + y + y = 18 + 2y

Ratio of P₁ and P₂ = [tex]\frac{2x+6}{18+2y}[/tex]

= [tex]\frac{2(\frac{y}{3})+6}{18+2y}[/tex] [as [tex]x=\frac{y}{3}[/tex]]

= [tex]\frac{\frac{(2y+18)}{3} }{(18+2y)}[/tex]

= [tex]\frac{2y+18}{3(18+2y)}[/tex]

Ratio of P₁ and P₂ = ([tex]\frac{1}{3}[/tex]) ⇒ P₂ = 3P₁

Therefore, Option a is the answer.

There are 20 children at a library. Six of the children have an average age of 5 years. The remaining children have an average age of 8 years. What is the average age of the children at the library? Enter your answer in the box. WILL GIVE BARINLIYEST

Answers

Answer: The average age is 7.1 years.

This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.

To start, lets multiply the total number of children by their individual ages.

6 x 5 = 30 years
14 x 8 = 112 years

There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.

If c=3k+4 and d=7+9k^2, what is d in terms of c?

Answers

Answer:

d = (c -4)² +7 = c² -8c +23

Step-by-step explanation:

Both 'c' and 'd' are expressed in terms of the variable k. In general, that variable is eliminated by writing k in terms of 'c' or 'd', then substituting for k in the other equation.

Eliminating k

We recognize that the 9k² term in the expression for 'd' is the square of the 3k term in the expression for 'c'. That means we don't have to solve for k; we only need to solve for 3k. The equation for 'c' gives an easy way to do that.

c = 3k +4

c -4 = 3k . . . . . . . subtract 4 to get an expression for 3k

Substituting into the equation for 'd', we have ...

d =7 +9k²

d = 7 +(3k)² . . . . . writing 9k² in terms of 3k

d = 7 +(c -4)² . . . . substituting for 3k. This is d in terms of c.

This can be simplified to ...

d = c² -8c +23 . . . . another form of d in terms of c.

Final answer:

To express 'd' in terms of 'c', solve the first equation for 'k' and substitute this value into the second equation. This yields: d=7+((c-4)^2)/3.

Explanation:

To express d in terms of c, we first need to make k the subject of c=3k+4. We do this by subtracting 4 from both sides, getting c-4=3k, and then dividing both sides by 3, which gives us k=(c-4)/3. Next, we substitute this value of k into the second equation: d=7+9k^2. Substituting, we get d=7+9*((c-4)/3)^2, which, when simplified, gives the result d=7+((c-4)^2)/3. This is the expression for d in terms of c.

Answers

Answer: Perfect squares are the middle two. Difference of squares are t^2 -4 and x^2 - 169

First, to be a perfect square the last term must be a perfect square number. Only 169, 49 and 16 are perfect squares. Second, the middle term must be twice the square root of the last term.

You can check this by using foil on the following expression:
(x + 13)(x + 13) You will get x^2 + 26x + 169 which is one of the perfect square trinomials.

For the difference of squares, you must be using subtraction and have two perfect squares.

t^2 - 4 and x^2 - 169 are the right answers, just took the test.

Suppose two fractions are both less than 1. Can their sum be greater than 1? greater than 2?

Answers

Their sum can be greater than 1 but it would be less than 2.

The biggest fraction which is less than 1 is 0.99

Sum of 0.99 + 0.99 = 1.98, which is greater than 1 but less than 2.

The sum can be greater than 1, but not two. For example say the fractions are, 3/4 and 5/6, the total is , 1 7/12. Which is greater than 1 but not two. It cannot be greater than 2 because fractions are a part of 1.UNLESS, it is a mixed number fractions, than they can be infinitely great. Such as 123 3/4 + 45 2/4 is definitely greater than 2.

Answers

Hello,

When you are looking for a ratio, it is simply a fraction.

In the numerator, we will put the amount of the increase which is 10.4 - 7.80 = 2.6.
In the denominator, we will put the original price of $7.80.

This gives us the ration of 2.6/7.8 or just 0.33 if we divide.
We can say there was a 33% increase (or one-third).

what formulas could be used to determine the surface area of a cylinder sandwiched between one cone and half of a sphere?

Answers

To find the surface area of a cylinder sandwiched between one cone and half of a sphere, use the sum of the cylinder's lateral surface area, the cone's lateral surface area, and half the sphere's surface area. The formula is 2πrh + πrl + 2πr², excluding the base areas where the shapes intersect.

To determine the surface area of a cylinder sandwiched between one cone and half of a sphere, you should first consider the formulas for the surface area of these individual shapes. The shapes consist of simple geometrical forms: a cylinder, a cone, and a sphere. The surface area of these shapes can be described with established formulas within the geometry:

Cylinder: The surface area of a cylinder (excluding the ends) is calculated by multiplying the perimeter of the base circle (which is 2πr, where r is the radius) by the height h of the cylinder plus the area of the two circles (2πr²). This gives: 2πrh + 2πr².Cone: The surface area of a cone is the sum of the area of its base (πr²) and the lateral surface area, which is πr times the slant height. However, if the cone is placed on one end of the cylinder and they share a base, you do not need to calculate the area of the base since it is covered by the cylinder. You would just need the lateral surface area of the cone (πrl, where l is the slant height).Sphere: Half of the surface area of a sphere is 2πr² since the full surface area is 4πr².

Therefore, the final formula to calculate the total surface area of the described complex shape is the sum of the surface area of the lateral side of the cylinder, the lateral surface area of the cone, and half of the surface area of the sphere. This could be written as:
Total Surface Area = 2πrh + πrl + 2πr².

Note that you would omit the area of the circle that is common between the cylinder and the cone, as well as the area that is common between the cylinder and the half-sphere, since they are internall and not part of the external surface area.

Answers

see attached picture for solution and graph

f(x)=x^2−12x+27
find Vertex (h, k)
x = h= -b/2a = -(-12)/2(1) = 6
k = f(h) = 36 - 12(6) + 27
k = -9

so vertex (6,-9)

y = a(x - h)^2 + k

so
y = (x - 6)^2 - 9
x intercept when y = 0
x^2−12x+27 = 0
(x - 9)(x - 3) = 0
x - 9 = 0; x = 9
x - 3 = 0; x = 3
so x-intercept (9,0); (3,0)

y intercept when x = 0 so y = 27 (0, 27)

OK now you can use these to graph the function

The first and fourth terms of a geometric sequence are shown.

−2,___ , ___, 128

What are the second and third terms of this geometric sequence?

Answers

geometric sequence nth term:
tₙ = t₁ · (r)ⁿ⁻¹

t₁ = -2
t₄ = 128 (4th term)

formula for 4th term:

t₄ = -2 · (r)⁴⁻¹ = -2· (r)³

since t₄ = 128

128 = -2(r)³
(r)³ = -64
r = ∛-64
r = -4

so second term is
t₂ = -2· (-4)²⁻¹ = 8

third term is
t₃ = -2 · (-4)³⁻¹ = -32

rectangle abcd is similar to rectangle pqrs. given ab=14 cm, BC=8cm and pq=21cm, calculate the length of QR

Answers

QR =12 because you set up a proportion 21/14=x/8 then cross multiply and get 14x=168 then you divide and get 12

The length of QR in rectangle PQRS is 12 cm, found by setting up the proportional relationship 14/21 = 8/QR, where 14 cm and 8 cm are the lengths of sides AB and BC of rectangle ABCD, respectively, and 21 cm is the length of side PQ of rectangle PQRS.

Since rectangle ABCD is similar to rectangle PQRS, their corresponding sides are proportional. To find the length of QR, we will set up a proportion using the given lengths:

AB/PQ = BC/QR

Substituting the given lengths:

14/21 = 8/QR

Now, solve for QR:

QR = (21 * 8) / 14

QR = 168 / 14

QR = 12 cm

So, the length of QR in rectangle PQRS is 12 cm.

This is a system of equations, and I am assuming that you are being asked to solve it.

This is finding the point where these two lines intersect.

The key to solving these algebraically is finding one part in terms of another part and substituting.

We can solve this system by Gaussian elimination, first by multiplying the second equation in its entirety by 2, so that the x-terms will cancel.

We have
[tex]16x-10y=10[/tex]
and
[tex]2(-8x-6y=6)[/tex].

The last equation is rewritten as [tex]-16x-12y=12[/tex].

Now, we cancel the x-terms.

[tex]16x-10y=10[/tex]
[tex]-16x-12y=12[/tex]

[tex]-22y=22 \\ y = -1[/tex]

We have our value for y, so we just plug this back into any of the original equations to get x.

[tex]16x-10(-1)=10\\16x=0\\x=0[/tex]

Thus, the solution to the system of equations is the point [tex](0,-1)[/tex].
