Answer:

Mel fills his gas tank up with 6 gallons of premium unleaded gas for a cost of $26.58. How much would it cost to full an 18 gallon tank?

or

Jacob ran 10 miles in 80 minutes. At that rate how far would he run in 2.5 hours?

Answer:

Width = 2w , Length = w+5 , perimeter = 40

Perimeter of rectangle = 2 (Length + Width)

P= 2 (L + w)

40 = 2 [ (w+5) + (2w) ]

40 = 2 ( 3w+5)

40= 6w +10

6w= 40 – 10

6w= 30

w = 30/6

w = 5

Width = 2w = 2(5) = 10

Length = w + 5 = 5+5 = 10

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 .

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:

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

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:

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:

A. P/2 - L = W

B. 9/5C + 32 = F

Step-by-step explanation:

A. P = 2L + 2W

P = 2(L+W)

P/2 = L + W

(P/2)-L = W

B. C = 5/9(F - 32)

9/5C = F - 32

9/5C + 32 = F

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

The value of tan A in triangle ABC is 12/5

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

In other words, it is the ratio of sine and cosine function of an acute angle such that the value of cosine function should not equal to zero.

Given is a right triangle ABC, with sides AB = 26, BC = 24, AC = 10

We are asked to find the value of tangent of angle A,

We know that, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

Therefore,

Tan A = BC / AC = 24/10 = 12/5

Hence, the value of tan A in triangle ABC is 12/5
