Answer:

39.63

Step-by-step explanation:

If the number after the place you are rounding to is 4 or lower, then you round down. If it is 5 or higher round up.

Answer:

the answer is: 39.63 and that is the answer

Answer:

I think 3 3/4 (A)

Step-by-step explanation:

Each gallon is 20 percent, while 3/4 is 75 percent. Divide 20 by 4, which is the denominator. The answer is 5. Every time you get a 5, that's a 1/4. For example:

25: 1 1/4

30: 1 2/4 (1/2)

35: 1 3/4

40: 2

Now, 75 is between 3 and 4 gallons, but it is lower than 4, so B and C are wrong. Let's do the math again.

65: 3 1/4

70: 3 2/4 (1/2)

75: 3 3/4

Remember, 3/4 is about 75%. which means, A is the answer!

Answer:

1- 42

2- 90

3- 45

Step-by-step explanation:

lxw=area

Answer:

Formula Length *width

You multiple the length by the width to get the answer

Rectangle 1. = 6*7 = 42

Rectangle 2. =9*10 = 90

Rectangle 3. =5*9 = 45

Answer:

1=88, 2=33, 3=88, 4=59

Step-by-step explanation:

59+33=92 and then you do 189-92 because angles on a straight line add to 180. this gives you 88.

then you can work out what angle 2 is because angles that are opposite are the same and thats the same for the other angles

The distance between Earth and the moon is 3.8 x 10^3 Kilometers. The time taken to travel this distance was 2.1 x 10^3 Minutes.

The formula to calculate speed is Speed = distance/time.

So, the speed of Luna I was 3.6 x 10^3 / 2.1 x 10^3 Kilometers/Mintues.

Answer:

Correct order: 17x^5+5x^3+4x-7

Degree: 5th-degree polynomial

Step-by-step explanation:

Descending order means from the highest degree to the lowest degree

This means the correct order is 17x^5+5x^3+4x-7 making the degree of the polynomial a 5th-degree polynomial.

Answer:

x = -20

Step-by-step explanation:

2.5(x - 4) = -60

~Distribute left side

2.5x - 10 = -60

~Add 10 to both sides

2.5x = -50

~Divide 2.5 to both sides

x = -20

Answer:

24 miles per gallon

Step-by-step explanation:

Step one:

given data

total distance covered= 480miles

The total amount of gallons used is = 20

The miles per gallon

= 480/20

=24 miles per gallon

Step two:

hence the equation that we used in solving the problem is stated as

miles per gallon= total distance/total gallon sused

Answer:

area = 2x² + 6x

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = length × width

   = 2x(x + 3) ← distribute parenthesis by 2x

    = 2x² + 6x

Answer:

3,552

Step-by-step explanation:

The possible scores are

259, 295,529, 592, 952, 925

These are all the possibilities from his selection. Hence the sum of all possible scores may be computed as

= 259 +295 + 529 + 592 + 952 + 925

= 3,552

the sum of all possible scores is 3,552

The solution to the equation m/(m+4) + 4/(4-m) = m²/ (m²- 16) is m= -4.

For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.

Given:

Quadratic equation,

m/(m+4) + 4/(4-m) = m²/ (m²- 16)

Simplifying,

{m(4-m) + 4(4+m)}/(4²-m²) =  m²/ (m²- 16)

4m - m² + 16 + m² =  m²/ (m²- 16) x (-(m²- 16))

-m² + 4m+16 = -m²

4m + 16 = 0

4m = -16

m = -4

Therefore, the value of m is -4.

Answer:

4 181 067.1 cm3

Step-by-step explanation:

Volume = height x pi x 2r

Volume = 315 x pi x 65 x 65 = 4181067.123

4181067.123 = 4 181 067.1 cm3

Answer:

v=pi×r^2×h (315cm=3.15m and 65cm=0.65m)

=3.14×0.65^2×3.15

=4.181 m

sorry if its wrong...

Answer :

x = -1.43

Explanation :

As given ,

The first box has a height (x+5) has a square base with side x

So, the Length and Breadth of the box are x and x respectively.

Now,

The volume of first box = Length×Breadth×Height

                                       = (x).(x).(x+5)

                                       = x²(x+5)

⇒The volume of first box = x²(x+5)

Now,

Given that , the second box with height (x+2) has a square base with side (x+5).

So, the Length and Breadth of the box are (x+5) and (x+5) respectively.

Now,

The volume of second box = Length×Breadth×Height

                                             =  (x+5). (x+5).(x+2)

                                              = (x+5)²(x+2)

⇒The volume of second box =  (x+5)²(x+2)

Now,

Given that,  the two boxes have the same volume

⇒x²(x+5) =  (x+5)²(x+2)

⇒x² =  (x+5)(x+2)

⇒x² =  x² + 2x + 5x + 10

⇒x² - x² =  7x + 10

⇒0 =  7x + 10

⇒ 7x = -10

⇒ x = -[tex]\frac{10}{7}[/tex] = -1.43

⇒ x = -1.43

As volume of first box = x²(x+5) = (-1.43)²(-1.43+5) = 7.30 ≈ 7

As volume of second box =  (x+5)²(x+2) = (-1.43+5)²(-1.43+2) = 7.26 ≈ 7

At x = -1.43, Volume of both the boxes are same.
