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.

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.

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: 132

X = 180 - 47 +1

x=132

Answer:

x = 67, 133 degrees

Step-by-step explanation:

2x - 1 + 47= 180

2x + 46 = 180

2x (+ 46 - 46) = 180 - 46

2x = 134

2x/2 = 134/2

x = 67

2x - 1

2(67) - 1

134 - 1

133 degrees

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!

or, x=23

Then,

x+115°

= 23+115°

Hey there again! :)

This function is a piecewise function and it's different from previous question.

As you may notice, the graphs are separated and some of coordinate points are not a part of domain and range. That's why we have separate domain and range.

First, let's consider that line graph. The one that contains (-2,0) and (0,-2).

Our domain is the set of all x-values. Only (-2,0) is a closed dot. We use [ ] for closed dot and ( ) for opened dot.

Hence, the first domain is [-2,0)

Next, we find the range of line graph or line segment.

Range is the set of all y-values. Hence, the first range is (-2,0]

We are not done yet! We have to find the second domain and range, which is a curve graph.

From the curve graph, our first point starts from (0,4) and ends at (5,4)

Since (0,4) is an opened dot and (5,4) is a closed dot.

Therefore, the second domain is (0,5]

For the range, the minimum point is (3,2) and maximum point is (0,4) and (5,4). Use the y-coordinate to find range.

Hence, the second range is [2,4}

Gathering Both Domain and Range

Combine both domains and ranges.

Hence, the domain is [-2,0] U (0,5] and the range is (-2,0] U [2,4] or The First Choice

Let me know if you have any questions!

Answer:

-1

Step-by-step explanation:

-2(2x + 4) + 10 = 8x + 14

-4x - 8 + 10 = 8x + 14

-4x + 2 = 8x + 14

-4x - 8x = 14 - 2

-12x = 12

x = -12/12
