Answer:

16 [tex]\frac{1}{2}[/tex] miles

Step-by-step explanation:

2 [tex]\frac{2}{4}[/tex] + 2 [tex]\frac{3}{4}[/tex] = 4 [tex]\frac{5}{4}[/tex] which equals 4 + 1 [tex]\frac{1}{4}[/tex] or 5 [tex]\frac{1}{4}[/tex]

5 [tex]\frac{1}{4}[/tex] + 3 = 8 [tex]\frac{1}{4}[/tex]

she ran 8 and one-quarter miles in the first week and if she ran the same amount the second week then we can add to get the answer:

8 [tex]\frac{1}{4}[/tex] +  8 [tex]\frac{1}{4}[/tex] = 16 [tex]\frac{2}{4}[/tex] or 16 [tex]\frac{1}{2}[/tex]

Answer:

-38 is an integer

Step-by-step explanation:

An integer is a whole-valued positive or negative number or 0. They are generated from the set of counting numbers 1, 2, 3,… and the operation of subtraction. So -38 is an integer.

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 :))

Answer:

See below.

Step-by-step explanation:

a.  Choose any 3 non-collinear points on the plane.  For example, plane R can be described as plane OSQ.

b.  "Collinear" means points that lie on the same line. Example: M, N, P (note that the line these points are on does not lie in plane R)

c.  [tex]\overrightarrow{NM}[/tex] and [tex]\overrightarrow{NP}[/tex]

d.  There are many. Examples: O, N, Q, S.  Not M. Not P.

Answer:

$5,400. 20% of 6,000 = 1,200. 1,200 * 4 1/2 (4.5) = $5,400 (bonus: 6,000 + 5,400 = $11,400) hope this helps

Answer:

102(5x+2y)+3x+6y−10

Step-by-step explanation:

Terms is each part of an algebraic expression separated by a plus or minus sign.

As 2(5x +2y ) , 3x , 6y2(5x+2y),3x,6y and 1010 .

Factor is a product of two or more numbers, algebraic variables or algebraic expressions . 2(5x +2y )2(5x+2y) has two factors 22 and (5x +2y )(5x+2y) .

3x3x has two factors 33 and xx .

6y6y has two factors 66 and yy .

-10−10 has one factors

Coefficient is the numerical factor of a term that contains a variable.

2(5x +2y ) the factor is 22 .

3x3x the factor is 33 .

6x6x the factor is 66 .

-10−10 the factor is -10−10 .

Variable is a symbol, usually a letter, used to represent a number.

As xx and yy

Constant is a term without a variable.

As -10−10 .

Answer:

The average value of the function over its domain

Answer:

{2 , 4} is the answer of this question.

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

x = -1

Answer:

27, 28, 29

Step-by-step explanation:

If you divide 84 by 3, the quotient will be in the middle of the three integers. We get 28 from dividing 84 by 3, therefore our string of numbers are 27, 28, and 29.

Answer:

x = 11

Step-by-step explanation:

From the diagram, we find,

(2x - 16) + (x - 8) = 9

=> 2x - 16 + x - 8 = 9

=> 2x + x - 16 - 8 = 9

=> 3x - 24 = 9

=> 3x = 9 + 24

=> 3x = 33

=> x = 33/3

=> x = 11

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
