twenty three less than sum of forty nine and thirty seven what is the answer?

Answer:

No

Step-by-step explanation:

An irrational number cannot be represented in the form a/b while a and b are integers and b isn't zero. We can write this number in this form:

6618/1000.

Since we can, it isn't irrational, it is actually rational

Hope this helps!

Answer:

Rational

Step-by-step explanation:

A rational number is any integer, fraction, terminating decimal, or repeating decimal.

So, the answer to this question would be no. This number is not irrational.

Answer:

The area of the square is 2.25cm

Step-by-step explanation:

Here's what we know:

-Each letter represent a side

-A square is made up of 4 congruent sides

-To find the area of a square you need 2 sides

-We have 2 sides (A and B)

Now we can solve:

If 3cm is the length of A and B together, then we can determine that separately The sides are 1.5cm. We can then multiply 1.5 by itself to get 2.25cm.

Answer:

D'(-4, 1)

Step-by-step explanation:

Polygon ABCDEF is transformed by number of steps given in the question.

We have to find the coordinates of point D'.

Coordinates of point D → (2, -2)

Step - 1,

Polygon rotated 90° counterclockwise about the origin,

Rule for this rotation,

(x, y) → (-y, x)

Coordinates of image E after rotation,

D(2, -2) → E(2, 2)

Step - 2,

Point E then reflected across the line y = -x,

Rule for the reflection,

(x, y) → (-y, -x)

Image of E after reflection will be,

E(2, 2) → F(-2, -2)

Step -3,

Then point F was translated up by 3 units and 2 units left,

Rule for the translation,

(x, y) → (x -2, y + 3)

Image of F will be point D',

F(-2, -2) → D'(-4, 1)

Answer:

So, the first five terms of the sequence defined by the given recursive function are shown below.

F(1) 0.75 f(2) 1.1 F(3) 1.45 F(4) 1.8 f(5) 2.15

Answer:

Inverse of cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction)

Step-by-step explanation:

According to trigonometry identity;

Cos 30° = √3/2

To get the expression equivalent to 30°, we will take the inverse of both sides as shown;

Cos^-1(cos 30°) = cos^-1(√3/2)

The arccos will cancel out the cos on the left hand side of the equation to have;

30° = cos^-1(√3/2)

Hence 30° is equivalent to inverse of cosine of √3/2 or Inverse of cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction)

Answer:

28 hours

Step-by-step explanation:

Divide the total cost of the new smartphone by how much Stacey earns per hour.

220 / 8 = 27.5

Round the quotient up to the nearest whole number to get your answer. We do this because Stacey would not get paid for only working part of an hour.

Answer:

D. Zn(NO3)2 + Cu

Step-by-step explanation:

The correct chemical equation for the replacement reaction of Cu(NO3)2 and Zn is:

Zn + Cu(NO3)2 → Zn(NO3)2 + Cu

A replacement reaction is a chemical reaction in which an element displaces or replaces another element in a compound. In other words, one element takes the place of another element in a compound.

The general equation for a replacement reaction is:

A + BC → AC + B

We have,

The reaction between copper nitrate (Cu(NO3)2) and zinc (Zn) is an example of a single replacement or displacement reaction, which involves the replacement of one element in a compound by another element.

In this reaction,

Zinc (Zn) reacts with copper nitrate (Cu(NO3)2) to form zinc nitrate (Zn(NO3)2) and solid copper (Cu).

The reaction is driven by the relative reactivity of the metals involved.

Zinc is more reactive than copper, which means that it has a greater tendency to lose electrons and form positive ions.

Copper, on the other hand, is less reactive and has a greater tendency to stay in its elemental form.

When zinc is added to copper nitrate solution, the zinc atoms lose electrons and become positively charged ions, while the copper ions in the solution gain electrons and become solid copper.

The zinc ions then combine with nitrate ions (NO3-) from the copper nitrate solution to form zinc nitrate, which remains in the solution.

The balanced chemical equation for the reaction shows that one molecule of zinc (Zn) reacts with one molecule of copper nitrate (Cu(NO3)2) to form one molecule of zinc nitrate (Zn(NO3)2) and one molecule of solid copper (Cu).

Thus,

The correct chemical equation for the replacement reaction of Cu(NO3)2 and Zn is:

Zn + Cu(NO3)2 → Zn(NO3)2 + Cu

Answer:

i have that same Question

Step-by-step explanation:

Answer:

Of course it doesn't work, 3 x 24 = 72, not 32 (3 tens and 2 ones)

Step-by-step explanation:

This method is similar to decomposition, but it doesn't work. The problem is that she is mixing multiplication, division and addition all together without any sense at all. The way decomposition works is as follows.

Examples of decomposition:

first you can multiply 3 x 4 = 12

then 3 x 20 = 60

add them and you get 72

for example: 6 x 122

6 x 2 = 12

6 x 20 = 120

6 x 100 = 600

add them together = 732

another example: 9 x 356

9 x 6 = 54

9 x 50 = 450

9 x 300 = 2700

add them to get 3,204

Step-by-step explanation:

If Kristens dog weighs 2.5 pounds less, then you just have to subrtact 2.5 from 18.25

The answer is B. 15.75 pounds. Kristen's dog weighs 2.5 pounds less than Milo's dog which is 18.25. So, all you have to do is subtract 2.5 from 18.25. 18.25 - 2.5 = 15.75.
