[tex]4\leq 4[/tex] True or false

Answer:

The top two pairs

Step-by-step explanation:

A similar polygon is when two pairs of a shape share the same scale factor, or when you multiply the sides by the same number, like a common denominator of a fraction. For example, for the first one, 18/4.5 is 4 and 6/1.5 is also 4. This means that this pair has a scale factor of 4, meaning it is a similar polygon.  Same for the top right. 40/8 = 5, and 15/3 = 5, making this also a correct answer. One the other hand, 1225/3.5 is 350, whereas 144/1.2 is 120, making this not a similar polygon. Finally, the last one. 13/2 = 2.5, whereas 5/2.5 is equivalent to 2, making this not a similar polygon.

Answer:

Time taken to cool your room (in hours) = (volume of your room* density of air* change in temperature you want * specific heat of air)/ (latent heat of fusion * ton capacity of your AC*1000 / 24).

Answer:

28

Step-by-step explanation:

So 1% of 350 would be 3.5 because 350 divided by 100 is 3.5. You then get 3.5 and multiply it 8 times, which would be 28. (You multiply it 8 times because 8% is 8 times 1%.) I hope this helps:)

Answer:

[tex]a_n=19+(n-1)(-5)[/tex]

Step-by-step explanation:

The explicit formula for an arithmetic sequence is [tex]a_n=a_1+(n-1)d[/tex] where [tex]a_n[/tex] is the [tex]n[/tex]th term and [tex]d[/tex] is the common difference.

In this problem, we can see that the first term of the sequence is [tex]a_1=19[/tex] and the common difference is [tex]d=-5[/tex] since 5 is being subtracted each consecutive term.

Therefore, the explicit formula that describes the given arithmetic sequence is [tex]a_n=19+(n-1)(-5)[/tex]

Answer:

option 2

Step-by-step explanation:

Let { a1, a2, a3, a4, ... } be the sequence.

now the 1st term (a1) will have a value when n = 1.

similarly, all the other terms will have the values given when we substitute their respective n values into the explicit formula or fibonacci sequence.

thus, check if the 1st term is 19 by using option 2

an = 19 + (n-1)(-5)

an = 19 + (n-1)(-5) ....n = 1

an = 19 + (n-1)(-5) ....n = 1 a1 = 19 + (1-1)(-5) = 19 + 0 = 19. so it's accurate so far.

next, check a2 where n = 2.

a2 = 19 + (2-1)(-5) = 19 - 5 = 14. ....

n = 3

a3 = 19 + (3-1)(-5) = 19 - 10 = 9.

hence the conclusion from this pattern.

Ocean Currents via their interaction with the Atmosphere and the Hydrosphere influence climatic behavior.

This is a continuous directional movement of seawater driven by gravity, wind, and water density.

This movement is predictable and can move vertically and horizontally.

Horizontal movements are called currents while vertical movements are called upwellings and downwelling.

Answer:

A) 7

Step-by-step explanation:

Because the triangles are congruent to each other, then their corresponding angles are also congruent to each other. Thus, angles Z and V are congruent to each other:

[tex]\angle Z=\angle V\\\\40^\circ=(5n+5)^\circ\\\\35=5n\\\\7=n[/tex]

Therefore, your answer is A.

Answer:

if you solve the equation it is 8 but the equation is 5-(-3) or 5+3 because two negatives equal a plus

Answer:

8

Step-by-step explanation:

The -3 is just substituting for the x. So if x=-3 you plug in -3 for x in the formula.

So when you plug it in you will have 5- -3. The two negative signs will make a positive. So you will have 5+3 and 5+3=8.

So f(-3)=8

Answer:

Step-by-step explanation:

We assume you want to evaluate the equation ...

  T = 32 +1.8t

for t = -8 2/3 and t = 8 2/3

The evaluation involves addition and multiplication, both of which are closed for all real numbers, which includes all rational numbers. The equation works for any rational numbers.

Your examples:

  T = 32 +1.8(-8 2/3) = 32 -15.6 = 16.4 . . . . the equation works

  T = 32 +1.8(8 2/3) = 32 +15.6 = 47.6 . . . . the equation works

Additional comment

Some calculators play nicely with decimals and mixed numbers.

The product 1.8(8 2/3) can be found as ...

  (1.8)(8 2/3) = 1.8(26/3) = 0.6(26) = 15.6

the sum of all interior angles in a polygon is

180(n-2)

n = number of sides

now, this one is a Heptagon, 7 sides, so the total of interior angles is 180(7-2) = 900.

add the two numbers and you get 407.1212. Subtract that from the solution and you get 85!!

Step-by-step explanation:

The equation for this problem would be 0.65x+1.75

Now, we just plug in the x (miles) in the equation until we get y less or equal to 10. I'm going to start at 5 as an estimate.

0.65(5) + 1.75 = $5

0.65(10) + 1.75 = $8.25

0.65(12) + 1.75 = $9.55

Step-by-step explanation:

The additional operation which needed to make the expression equivalent to given expression is [tex]-\dfrac{3}{4} x[/tex]. Thus the option 3 is the correct option.

Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.

Given information-

The equation given in the problem is,

[tex]\dfrac{5}{4} x+6[/tex]

Let the equation is equation number 1.

This expression is to convert in the expression, which is,

[tex]\dfrac{1}{2}x+6[/tex]

Let the above equation is equation number 2.

Let the additional operation which needed to make the expression equivalent to given expression is [tex]f(x)[/tex].

As the addition of [tex]f(x)[/tex] and equation 1 is equal to the equation 2. Therefore,

[tex]f(x)+\dfrac{5}{4} x+6=\dfrac{1}{2}x+6[/tex]

Solve the equation as,

[tex]f(x)=\dfrac{1}{2}x+6-\dfrac{5}{4} x-6\\f(x)=\dfrac{1}{2}x-\dfrac{5}{4} x\\f(x)=\dfrac{2-5}{4} x\\f(x)=\dfrac{-3}{4} x[/tex]

Hence, the additional operation which needed to make the expression equivalent to given expression is [tex]-\dfrac{3}{4} x[/tex]. Thus the option 3 is the correct option.
