A middle-school art teacher, Ms. Velez, and her students are turning the school’s gymnasium into a student art museum for the day.
Ms. Velez types a program for the event and writes: "The most popular art museum in the world, the Louvre, has approximately 9,300,000 visitors each year. About 1,900,000 of those visitors are young people age 18 to 25."
1) How would you write the two numbers above in scientific notation? (2 points)
2) BONUS: Approximately what percent of visitors to the Louvre are young people?

Answer: 3a - 7

Step-by-step explanation:

(-4a - 3) + (7a - 4)

Combine like terms

-4a + 7a - 3 - 4

3a - 7

Answer: {(0, 1), (2, 3), (4, 5), (7, 8)}

Step-by-step explanation:

For the function:  y = x - 1    (y is one less than x)

If x =1 , y= 0

if x= 3 . y= 2

If x = 5 , y= 4

If x= 8 , y= 7

So it is same as

x y

1 0

3 2

5 4

8 7

But different from {(0, 1), (2, 3), (4, 5), (7, 8)} [here x is 1 less than y]

So,  the complete statement would be : All of the following represent the same function except {(0, 1), (2, 3), (4, 5), (7, 8)} .

Step-by-step explanation:

Remark

This is an incredibly beautiful problem! It is solved mostly by algebra. r = 1 and the height will therefore be 2

Equations

l^2 + r^2 = l^2

l is the slant height.

Solution

SA = π * l * r + π r² = π(1 + √5)          Divide both sides by π

Find l

l * r + r^2 = 1 + √5

l^2 = r^2  + h^2

l^2 = r^2 + (2r)^2

l^2 = 5r^2

l = √5 * r

Now go back to this equation to find r

l * r + r^2 = 1 + √5                               Substitute the value for l

√5 r * r + r^2 = 1 + √5                         On the left pull out r^2

r^2 (1 + √5) = 1 + √5                            Divide by 1 + √5

r^2 = 1                                                  Take the square root on both sides

sqrt(r^2) = sqrt(1)

r =1

Therefore h = 2

Volume of the cone.

V = 1/3 * π r² h

V = 1/3 * π 1² 2

V = 2/3 * pi

D

Answer:

The answer is ;

9x/2y^2

Step-by-step explanation:

Here, we want to simplify as far as possible

Let us take all the numbers one after the other

All numbers on numerator and denominator;

(4 * 9)/(2 * 4) = 9/2

All x

(x^2 * x^2)/(x^2 * x) = x

All y

(y^4 * y^4)/(y * y^9) = y^8/y^10 = 1/y^2

So the complete answer is;

9/2 * x * 1/y^2

= 9x/2y^2

Check batteries=20

Battreies do not have charge=14

Out of the next batteries that you check=70

Expect to not have charge=30

Answer is 30.

Step-by-step explanation:

Number of batteries do not have charge from 20 batteries is 49 batteries

What information do we have?

Number of batteries do not have charge from 20 batteries = 14 batteries

Using ration of total batteries to do not have charge batteries

Number of batteries do not have charge from 70 batteries = 70[14/20]

Number of batteries do not have charge from 70 batteries = 7[7]

Number of batteries do not have charge from 20 batteries = 49 batteries

I got this answer right on my test

Table 1 and table 3 are represent linear functions of x.

A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra.

Given are four tables, we need to find that which of them shows linear functions of x,

Linear functions will have the ratios of x and y coordinates, constant.

In table 1 :-

x/y = -1/2

-2/4 = -1/2

-3/6 = -1/2

Since the x and y coordinates are constant, therefore, the function is linear.

In table 2 :-

x/y = 1/1 = 1

2/4 = 1/2

3/9 = 1/3

Since the x and y coordinates are not constant, therefore, the function is not linear.

In table 3 :-

x/y = 1/5

2/10 = 1/5

3/15 = 1/5

Since the x and y coordinates are constant, therefore, the function is linear.

In table 4 :-

x/y = 1/1 = 1

2/8 = 1/4

3/27 = 1/9

Since the x and y coordinates are not constant, therefore, the function is not linear.

Hence, table 1 and table 3 are represent linear functions of x.

Answer:

I'm sure you mean miles, but the car will travel 135 mites.

Step-by-step explanation:

(180/4)3 = 135 miles. The car will be traveling at 45 miles per hour since 180 miles divided by four hours is 45, then you can multiply that by three to get the distance the car will travel in the next three hours. A function that models this equation is f(x)=45x.

Answer:

x is 10

Step-by-step explanation:

Form the diagram, you can see that UV is parallel to TS, this means that <UVS  = < UTS

Given

<UVS = 5x + 38

<UTS = 12x - 28

Since the sum of opposite angle of a quadrilateral is 180 degrees, hence;

5x + 38 + 12x - 28 = 180

Collect like terms

5x + 12x - 28 + 38 = 180

17x + 10 = 180

17x = 180-1-

17x = 170

x = 170/17

x = 10

hence the value of x is 10
