Answer:

10

Step-by-step explanation:

With this question you must find the LCM for 2 and 5.

Multiples of 2= 2,4,6,8,10

Multiples of 5= 5,10

10 is the least common multiple making it the first number that the boxes can be at the same height with.

Answer:

a = 6 and b = -1.

Step-by-step explanation:

To find the maximum value of y = -x²+ ax + b we differentiate it with respect to x to find the value of x at which it is maximum.

So dy/dx = d(-x²+ ax + b)/dx = -2x + a

we equate it to zero.

-2x + a = 0

-2x = -a

a = 2x

Now, given that x = 3 at the maximum value,

a = 2x = 2(3) = 6

Also, substituting y = 8 and x = 3 into y, we have

y = -x²+ ax + b

8 = -(3)²+ a(3) + b

8 = -9 + 3a + b

3a + b = 8 + 9

3a + b = 17

So, b = 17 - 3a

substituting a = 6, we have

b = 17 - 3(6)

b = 17 - 18

b = -1

So, a = 6 and b = -1.

Answer:

6^2 = 36

Step-by-step explanation:

The number that best approximates the square of 6 is 36, its actual value. The point so labelled is the appropriate point on the number line.

7.7 is the point on the number line is the best approximation for √59

A number system is defined as a system of writing to express numbers.

A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

Approximation or approximate numbers can be defined as a value that is similar to the other value but not exactly equal to it.

We need to find the approximation of √59

We have given √59

We need to remove the radical

=7.681=7.7=8

We can place the dot on 7.7 of the number line.

Hence 7.7 is the point on the number line is the best approximation for √59

Area = 8,100 square feet

area of a square = a²

8,100 square feet = a²

√8,100 square feet = √a²

90 feet = a

total length each row of bookshelf is 4/5 of the length of the storage space.

90 feet * 4/5 = (90*4)/5 = 360/5 = 72 feet.

Area = (72 ft)²

Answer:

Approximately 0.51

Step-by-step explanation:

If events A and B are independent, then P(A and B) = P(A)*P(B) is a true equation.

We're given the following

     P(A) = 0.65

     P(A and B) = 0.33

So,

P(A and B) = P(A)*P(B)

0.33 = 0.65*P(B)

P(B) = 0.33/0.65

P(B) = 0.5076923076923

which is approximate. When we round to 2 decimal places, we get 0.51

Answer:

A, $151.36

Step-by-step explanation:

Step #1: Change 5.3% to a decimal.

To do that just move the decimal point 2 places to the left (same thing as dividing by 100). Also remember that every number has invisible zeros in front of it that don't change the number at all.

So basically to change 5.3% to a decimal just move the decimal point in front of 5 (that's one time), then in front of the invisible zero (that's 2 times) so you have .053

Step #2: Then multiply .053 times $143.74

The answer should be $7.61822 if you did it right.

Step #3: Add #143.74 and $7.61822 to find the total with the sales tax.

The answer should be $151.35822.

But we don't do that in money so round the total to the nearest cent. Look at the third decimal space to see if you're rounding up or down. If the decimal space is 0-4, then round down (so in this case if the 8 was a 2, you would keep the 5 like it is and the answer would be $151.35). But if the third decimal space is 5-9, then round up.

In this case since the third decimal space is a 8, we are rounding up and changing the 5 to a 6.

So your final answer should be $151.36.

Given:

In a right angle triangle,

Hypotenuse = x

Other two sides are (x-2) and 8.

To find:

The value of x.

Solution:

According to the Pythagoras theorem,

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

Putting the given values, we get

[tex]x^2=(x-2)^2+(8)^2[/tex]

[tex]x^2=x^2-4x+4+64[/tex]

[tex]x^2-x^2+4x=68[/tex]

[tex]4x=68[/tex]

Divide both sides by 4.

[tex]x=\dfrac{68}{4}[/tex]

[tex]x=17[/tex]

Therefore, the value of x is 17.

Answer:

219.375

Step-by-step explanation:

Speed = distance / time

67.5 = distance / 3.25 hours

Multiply both sides by 3.25

67.5 x 3.25 = 219.375

Answer:

The Train Could travel 219.375 MPH

Step-by-step explanation:

67.5 × .25 = 16.87567.5 × 3 = 202.516.875 + 202.5 = 219.375

Answer:

Step-by-step explanation:

Using h and b to represent the prices of hockey and basketball tickets, respectively, the two purchases are ...

  2h +b = 173.01

  h +2b = 162.99

Subtracting the second equation from twice the first gives ...

  2(2h +b) -(h +2b) = 2(173.01) -(162.99)

  3h = 183.03

  h = 61.01

Substituting that into the first equation, we can solve for b:

  b = 173.01 -2h = 173.01 -2(61.01)

  b = 50.99

The average cost of an NHL ticket was $61.01.

The average cost of an NBA ticket was $50.99.

Since the values on both sides are different, hence the  the system of inequalities have NO solutions

Inequalities are equation that does not include only the equal sign.

Given the following inequalities

y > - 1/3x+5 and y< - 1/3 x -1

In order to determine whether the equations have a solution, we need to equate both expressions and solve

Equate

-1/3x + 5 = -1/3x - 1

-1/3x + 1/3x  = -1 - 5

0x = -6

Since the values on both sides are different, hence the  the system of inequalities have NO solutions
