What is the area of the real store in square inches? What is the area of the real store in square feet? What are the dimensions (length and width) of the store in feet? Is it a big store or a small one? PLEASE HELPP!!

Answers

Answer 1

Answer:

The dimensions of the real store are 80 times bigger as per scale:

1.875 in * 80 = 150 in = 150/12 ft = 12.5 ft2.25 in * 80 = 180 in = 180/12 ft = 15 ft

The area of the real store:

150 in * 180 in = 27000 in²12.5 ft * 15 ft = 187.5 ft²

Which expression represents all the solutions to the inequality
3(2x - 8) > 4x + 26?

Answers

Answer:

x > 25

Step-by-step explanation:

3(2x−8)>4x+26

Step 1: Simplify both sides of the inequality.

6x−24>4x+26

Step 2: Subtract 4x from both sides.

6x−24−4x>4x+26−4x

2x−24>26

Step 3: Add 24 to both sides.

2x−24+24>26+24

2x>50

Step 4: Divide both sides by 2.

x>25

vamsi is X years old.his brother is 3 years elder to him. his uncle is 4 times his age and his aunt is 5 years younger than his uncle.what are the ages of vamis brother, uncle and aunt? what will be the age of his uncle 6 years from now

pls send the ans fast

Answers

Step-by-step explanation:

Vamsi is X years old

Vamsi = X

his brother is 3 years elder to him

Brother = X + 3

his uncle is 4 times his age

Uncle = 4X

his aunt is 5 years younger than his uncle

Aunt = Uncle - 5

what will be the age of his uncle 6 years from now

= 4X + 6

what are the ages of vamis brother, uncle and aunt?

Assume Vamis = 15 years

Brother = X + 3 = 15 + 3 = 18

Uncle = 4X = 4 * 15 = 60

Aunt = Uncle - 5 = 60 - 5 = 55

what will be the age of his uncle 6 years from now

Uncle = 4X + 6 = 60 + 6 = 66

An isotope of cesium-137 has a half-life of 30 years. If 5.5 grams of cesium-137 disintigrates over a period of 105 years, how many grams of cesium-137 would remain? Round your answer to the thousandths place.

Answers

Answer:

0.484 g

Step-by-step explanation:

N/No = (1/2)^t/t1/2

No = mass of cesium-137 originally present

N= mass of cesium-137 at time t

t1/2= half life of cesium-137

t = time taken

N/5.5=(1/2)^105/30

N/5.5=(1/2)^3.5

N/5.5= 0.088

N = 5.5 * 0.088

N= 0.484 g

Answer:

x = 7x = 4x = 5x = 2

Step-by-step explanation:

The general steps are ...

look at what you haverewrite the equation so the variable terms are on one side and the constant terms are on the other side of the equal sign; collect termsdivide by the coefficient of the variable

It is generally convenient to put the variable terms on the side of the equation having the largest (most positive) variable term. You do the rearranging by subtracting the terms you don't want. Any operation is performed on both sides of the equation.

1) 3x + 7 = 4x

We observe the largest x-term is on the right, and the only constant term is on the left. We can subtract the x-term 3x to eliminate it from the left side

3x +7 -3x = 4x -3x

Combining like terms gives ...

7 = x . . . . . this is the solution

2) x +2 +2x = x + 10

We observe x-terms and constants on both sides of the equation. First of all, we will combine like terms.

3x +2 = x +10

The largest x-term is on the left, so we choose to subtract x (the x-term on the right)

3x -x +2 = x -x +10

2x +2 = 10

We don't want the constant on the left, so we subtract 2.

2x +2 -2 = 10 -2

2x = 8 . . . . . . . . . . combine like terms

Now, we divide by the coefficient of x.

2x/2 = 8/2

x = 4 . . . . . . the solution

3) x +3x = x + x + 10

4x = 2x +10 . . . . . . . combine like terms

2x = 10 . . . . . . . . . . . subtract 2x

x = 5 . . . . . . . . . . . . . divide by 2

4) 2x +3 + 3x = x + 11

5x +3 = x +11 . . . . . . . . combine like terms

4x +3 = 11 . . . . . . . . . . . subtract x

4x = 8 . . . . . . . . . . . . . . subtract 3

x = 2 . . . . . . . . . . . . . . .divide by 4

_____

Learn to identify and combine like terms. Use addition or subtraction to eliminate terms you don't want. Use multiplication or division to eliminate coefficients you don't want. Whatever you do to one side of the equation must also be done to the other side of the equation. (In the above, we use "subtract ..." to mean "subtract ... from both sides of the equation," for example.)

Serenity has a toy car collection. She keeps some in a display case and the rest on the
wall.
104
of her toy cars are on the wall, and 74% of her toy cars are in the display
case. What is the total number of toy cars in Serenity's collection?

Answers

If 74% are in the display, then 100% - 74% = 26% are hung on the wall.

This means 104 cars is 26% of her collection.

To find the total collection divide the number on the wall by the percentage of the collection:

104/0.26 = 400

The total number of her collection is 400 cars.

Why am i wrong? Trigonometric Ratios. Real answers only!

Answers

Answer:

You may have gotten the opposite and adjacent mixed up.

[tex]\frac{24}{7}[/tex]

Step-by-step explanation:

An easy way to remember these trigonometric ratios is by using SOHCAHTOA, where:

SOH stands for-

[tex]Sine=\frac{Opposite}{Hypotenuse}[/tex]

CAH stands for-

[tex]Cosine=\frac{Adjacent}{Hypotenuse}[/tex]

TOA stands for-

[tex]Tangent=\frac{Opposite}{Adjacent}[/tex]

We are asked to find tan 74° given the right triangle. To find this, we must find the lengths of the opposite side and the adjacent side of the 74° angle. From looking at the triangle, we can see that the side opposite from the 74° angle is 24, and the adjacent is 7. So plugging it into the trigonometric ratio that we found using SOHCAHTOA, we find that:

[tex]tan74=\frac{24}{7}[/tex]

So the answer would be [tex]\frac{24}{7}[/tex]

Seeing as how you picked [tex]\frac{7}{24}[/tex] as your answer, it seems that you may have gotten the opposite and the adjacent mixed up or used [tex]tangent=\frac{adjacent}{opposite}[/tex] as your trigonometric ratio.

I hope you find my answer and explanation to be helpful. Happy studying.
