Answer:

640/20 is 32

hope it's helpful

When the number 640 is divided by the number 20, the result is 32.

To divide 640 by 20, we perform long division or use the concept of division as the inverse of multiplication. By dividing 640 by 20, we are essentially finding how many times 20 can be evenly divided into 640.

On Dividing 640 by 20 yields a quotient of 32. This means that 20 can be divided into 640 exactly 32 times, without any remainder.

Thus, 640 divided by 20 is equal to 32. In simpler terms, if we distribute 640 items into 20 groups, each group will contain 32 items.

Answer: 19 macaroons

Step-by-step explanation:

Let's create an equation to represent this situation. Let x represent the number of macaroons that Em made.

33=x+x+5

33=2x+5

33-5=2x+5-5

28=2x

28/2=2x/2

14=x

This means that Em made 14 macaroons.

14+5=19

Therefore, Jim baked 19 macaroons.

or, 115=6x - x

or, 115=5x

or, 115/5 =x

Work Shown:

(distance)/(gallons used) = (distance)/(gallons used)

(333 miles)/(37 gallons) = (486 miles)/(x gallons)

333/37 = 486/x

333x = 37*486 .... cross multiplication

333x = 17,982

x = (17,982)/333

x = 54 gallons

You need 54 gallons to travel 486 miles.

[tex]f(x)=2x^2-44x+185\\\\=2(x^2-2*11*x)+185\\\\=2(x^2-2*11*x+11^2)+185-2*121\\\\\boxed{f(x)=2(x-11)^2-57}\\\\vertex\ is\ (11,-57)[/tex]

Answer:

f(x) = 2(x - 11)² - 57

Step-by-step explanation:

Given

f(x) = 2x² - 44x + 185 ( factor out 2 from the first two terms )

f(x) = 2(x² - 22x) + 185

To complete the square

add/ subtract ( half the coefficient of the x- term )² to x² - 22x

f(x) = 2(x² + 2(- 11)x + 121 - 121 ) + 185

     = 2(x - 11)² + 2(- 121) + 185

    = 2(x - 11)² - 242 + 185

f(x) = 2(x - 11)² - 57 ← in vertex form

The absolute value of 7 is positive 7 because the distance from zero to 7 on the number line is seven units.

The absolute value of -9 on the number line will be 9 units from zero.

Explanation:

Given :

1) Four statements describing absolute value.

2) The absolute value of -9 on a number line.

To find:

1) The true statement.

2) The absolute value of -9 on the number line.

Solution:

1)

The absolute value of a number can also be thought of as the distance from zero along the number line of a real number.

|7|=7

The absolute value of '7' is 7.

This is because the distance from zero to 7 on the number line is seven units.

The statement B is true.

2)

The absolute value of -9:

|-9|=9

The absolute value of -9 on the number line will be 9 units from zero.

Domain and range are the possible values a function can take as input and output, respectively.

Given that:

[tex](b,M) \to[/tex] The ordered pair

Where:

[tex]b \to[/tex] Number of bags of mandarins

[tex]M \to[/tex] Number of mandarins

To determine the domain and range, we consider the following:

The shelf can hold a maximum of 20 bags implies that the domain of the relation is from 0 to 20. i.e. [tex]0 \le b \le 20[/tex]

When there is no bag on the shelf, the number of mandarin is:

[tex]M = 12 \times 0 = 0[/tex]

When the shelf has the maximum (i.e. 20 bags), the number of mandarin is:

[tex]M = 12 \times 9 = 108[/tex]

This implies that the range of the relation is: [tex]0 \le M \le 108[/tex]

Answer: 9

Concept:

The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half.

In other words, the median of a set of data is the middlemost number or center value in the set.

Solve:

STEP ONE: Line up the terms in the set from least to most

Given = 2, 7, 10, 8, 9, 10, 15

Line up = 2, 7, 8, 9, 10, 10, 15

STEP TWO: Find the middlemost number

Given = 2, 7, 8, 9, 10, 10, 15

Since it is an odd set, therefore there should be the equal number of terms in the lower and higher half.

There are in total seven terms, therefore, the 4th term would be the middlemost, which is [tex]\boxed{9}[/tex].

Answer:

first triangle (to left) b=8, second one c=17

Step-by-step explanation:

for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.

A^2   +  B^2  = C^2

^              ^          ^

^              ^         Hypotenuse

^        second side

first side

Substitute:

5^2 + b^2 = 9^2

SImplify:

25+b^2 = 81

Reduce:

b^2 = 64

Simplify:

b=8

In the second triangle, we are given 2 sides.

Let's do the same thing we did in the first one.

Givens:

A = 8

B = 15

Find:

C

Substitute:

8^2 + 15^2 = c^2

Simplify

64 + 225 = c^2

Reduce:

289 = c^2

Let's now square root both sides

square root of 289 is 17

so we are left with this:

c=17

Phew, you did it!

Hope this helped :))
