What is the sum of 2/ 10 +6/100​

Answer:

(18 miles/inch)(14 inches) = 252 miles

The distance between Nashville and Memphis is 252 miles.

Using the map scale of 1 inch to 18 miles, the distance between Nashville and Memphis, given as 14 inches apart on the map, is calculated to be 252 miles.

The question involves calculating the actual distance between two cities using a map scale. In order to find the distance between Nashville and Memphis, we'll use the scale given on the map to convert inches into miles.

The map scale is 1 inch:18 miles. Since the cities are 14 inches apart on the map, we can set up a simple multiplication to find the distance:

Therefore, the actual distance between Nashville and Memphis is 252 miles.

OPTION C - Distributive Property

Step-by-step explanation:

Given: [tex]$ \frac{6x + 9}{3} $[/tex]

This is equal to: [tex]$ \frac{6x}{3} + \frac{9}{3} $[/tex]

⇒ [tex]$ 2x + 3 $[/tex]

Here, [tex]$ 3 $[/tex] is distributed over each term. Hence, distributive property is used.

Answer:

C. Distributive property

Step-by-step explanation:

From the question,

      [tex]\frac{6x+ 9}{3}[/tex] =  [tex]\frac{6x}{3} + \frac{9}{3}[/tex]     (distributive property of the denominator)

             = 2x + 3

The denominator in the question is distributive over the two terms in the numerator.

Answer:

1/5

Step-by-step explanation:

First, put the equation into slope-intercept form: y=mx+b, where m is the slope and b is the y-intercept.

5y=x+10, then divide both sides by 5;

y=1/5x+2

The slope is m, and m=1/5.

Answer:

y=-2x+7

Step-by-step explanation:

Memorize the formula y=mx+b where m=slope and b=y-intercept.

y=-2x+b passes through the point (1, 5)

5=-2(1)+b

5=-2+b

b=5-(-2)=5+2=7

Which is obviously not true.

Without Table 14, a specific answer can't be provided. But generally you would find the y value when x is 3 for f(3), or find the x value when y is 1 for f(x)=1.

This question pertains to the evaluation of f(3) and solving for f(x)=1 within the given function f that's represented in Table 14. Unfortunately, as the Table 14 isn't provided, I can't give a specific answer. However, generally, to evaluate f(3), find the pair where the x value is 3; the corresponding y (or f(x)) value is the result of f(3). To solve f(x)=1, look for the pair in the table where the f(x) (or y) value is 1; the corresponding x value is the solution for f(x)=1.

Answer:

Step-by-step explanation:

20%=0.2

0.2*30=6

Answer:

We need to use the compound interest formula where the future amount is determined by

A = P(1 + r/n)nt

A = future or present amount = 5,000,000

P = initial amount invested = 8,000

r = interest rate as a decimal (to be determined)

n = # times compounded in a year = 1

t = # years = 200

5000000 = 8000(1+r/1)1(200)= 8000(1+r)200

(1+r)200 = 5,000,000/8,000

(1+r)200 = 625

1+r = 200√625

1 + r = 6251/200

r = 6251/200 - 1 = 0.0327

r ≅ 3.27%

Step-by-step explanation:

3.27% is interest rate compounded annually would this growth occur.

What exactly does "interest rate" mean?

The formula is -

A = P(1 + r/n)nt

given,

A = 5,000,000

P = 8,000

r = ?

n =  1

t =  200

put all the value in formula

5000000 = 8000(1+r/1)1(200)

5000000 = 8000(1+r)200

(1+r)200 = 5,000,000/8,000

(1+r)200 = 625

(1+r) = 200√625

(1 + r) = 6251/200

r = 6251/200 - 1

r = 0.0327

Answer:600

Step-by-step explanation:

The 6 is in the hundreds place, so you in order to round it you would look at the 4. Since 4 is a a number less than 5 you round down. That would mean 600 instead of 700.

Answer: 600

Step-by-step explanation: To round 649 to the nearest hundred, we first find the digit in the rounding place which in this case is the 6 in the hundreds place.

To decide whether to round up or down, we look at the digit to the right of the 6 which is 4.

According to the rules of rounding, if the digit to the right of the rounding place is less than 5, we round down.

So in this problem, since 4 is less than 5, we round down.

This means that the 6 in the hundreds place stays the same and all digits to the right if 6 become 0.

So 649 rounded to the nearest hundred is 600.

Find the circumference of the road roller

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

we have

[tex]r=77\ cm[/tex]

Convert to meters

[tex]r=77\ cm=77/100=0.77\ m[/tex]

assume

[tex]\pi =3.14[/tex]

substitute

[tex]C=2(3.14)(0.77)[/tex]

[tex]C=4.8356\ m[/tex]

step 2

Calculate the number of revolutions that the roller will take to cover an area of 96.8 meter square

Remember that

The circumference of complete circle subtends one revolution

The circumference multiplied by the wide of road roller is equal to the area cover for the roller in one revolution

[tex]wide=80\ cm[/tex] ----> [tex]wide=0.80\ m[/tex]

[tex]4.8356(0.80)=3.86848\ m^2[/tex]

so

using proportion

Find out the number of revolutions for an area of 96.8 meter square

[tex]\frac{3.86848}{1}\ \frac{m^2}{rev}=\frac{96.8}{x}\ \frac{m^2}{rev} \\\\x=96.8/3.86848\\\\x=25\ rev[/tex]

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Sum the given angles and equate to 360

x + 2x + 114 + x - 10 = 360, that is

4x + 104 = 360 ( subtract 104 from both sides )

4x = 256 ( divide both sides by 4 )

well, if we open the fixed sides, we'll end up with a 3rd side of 2.5 + 8 = 10.5, however if "x" is ever 10.5, the figure will become a flat-line and we'd be losing the triangle.

and if we close the fixed sizes, the longest "x" could be is 8 - 2.5 = 5.5, but the same, it can't be 5.5 exactly otherwise the figure will turn to a flat-line.

GCF of 38 and 48

First find the prime factorization of 38 and 48.

38=2*19

48=2*2*2*2*3

The two number share the factor 2 and only 2. The GCF = 2.

Final answer:

The greatest common factor (GCF) of the number 38 is technically 38 itself. However, in the context of two or more numbers, it's the largest factor they share in common. For the single number 38, its factors are 1, 2, 19, and 38.

Explanation:

Finding the Greatest Common Factor (GCF) of 38

The greatest common factor of a number is the largest number that divides it, other than the number itself. Since 38 is a composite number and not a prime number, its factors are 1 and 38. The number 38 can also be divided evenly by 2 and 19, because 38 = 2 × 19. So, the factors of 38 are 1, 2, 19, and 38 itself. However, when we refer to the greatest common factor, it is usually in the context of finding the GCF between two or more numbers. For the single number 38, the GCF can be considered as the largest factor, which is 38 itself. But typically, the term 'greatest common factor' is more relevant when comparing it with another number to see the largest factor they have in common.

Final answer:

To express (x + 4)(x - 2) + 3x as a trinomial, expand the product, combine like terms, and then add the additional term which results in the trinomial x² + 5x - 8.

Explanation:

To perform the indicated operations and express as a trinomial, we need to expand the binomial product and combine like terms with the additional term.

First, we expand the product: (x + 4)(x - 2) = x² - 2x + 4x - 8

Next, we combine the terms within the product: x² + (4x - 2x) - 8 = x² + 2x - 8

Now, we add the additional term: (x² + 2x - 8) + 3x

Lastly, we combine like terms: x² + (2x + 3x) - 8 = x² + 5x - 8

Step-by-step explanation:

If x is the number of t-shirts, and y is the number of sweatshirts:

10x + 15y ≥ 500

x + y ≤ 50

y ≥ x/2

And since x and y can't be negative:

x ≥ 0

y ≥ 0

Graph:

desmos.com/calculator/mw6dsei6jm

The boundaries of the feasible region are:

(0, 50), (0, 33.3), (28.6, 14.3), and (33.3, 16.7)

Since x and y must be integers, any non-integer solutions are not viable.

The maximum profit will be when the most product is sold.  Since sweatshirts are more profitable, we want to sell as much of that as we can.  

So they should sell 0 t-shirts and 50 sweatshirts for a maximum profit of $750.
